According to remote control unit 20 of the present invention advantageously is a kind of scheme of general-purpose formula; Thereby be applicable to any modular of protection system 1; And only difference is the length of connector parts 6, and said connector parts 6 are to be used for its handle 50 is fixed to related with it module 2,12.Under extreme case, the drive link of remote control unit 20 70 need opposing with the inertia force of realizing motion positions by on the right monitoring means 12 ₁With four utmost points 2 _i, and/or four control/monitoring modulars 12 of on the left side _iProduce.And switch element 2 itself, circuit breaker, switch or decoupler can comprise from 0.5 or the scope of 10A to 125A, and comprise for example differential switch of difference in functionality that said difference in functionality has hinted the different steering forces that applied by handle 50.

Structure according to protection system 1; Obviously; The mechanical force and the stress that act on the drive link 70 are far from it; Yet enough accuracy need be kept in the position to drive link 70, need not change order (power and moment of torsion) and information (speed, stroke, gap etc.) so that guarantee the reliability of system 1.Particularly, drive link 70 can not cause any dysfunction because of its functional insertion between auxiliary member 12 and circuit breaker 2.Thereby, according to the present invention, when masterpiece is used second end 72 of drive link 70; Drive link 70 is kept less than 0.15mm in the transversely deforming of first end 71; Preferably less than 0.1mm, and said power usually thinks and equals every utmost point 3N, and when second end 72 receives the vibration at end of travel place; Particularly when handle 50 is in closure or open position, run in the situation that the card that is made up of front panel 26 ends, said vibration can have the semisinusoidal intensity of the regularization of about 15g/11ms.

According to the present invention, the drive link 70 of remote control unit 20 is by the material of aluminium or magnesium alloy type or preferably processed by the Zamak to humidity and/or temperature-insensitive, for example processes through the injection molding of metal.The length of drive link 70 between its two

ends

71,72 is by unit L ₂₀Size confirm, i.e. preferably approximately 60mm or 80mm, the thickness of drive link 70 is chosen to make bar 70 under the effect of actuating force and resistance, can perhaps can not be out of shape hardly.Particularly, big body thickness is about 0.7mm, and at the critical component place reinforcement is arranged, particularly in

end piece

73,74 with at the height place of pivot pin 77.Because not circuitous, thus realized the information between switch element 2 and the auxiliary member 12 and/or ordered optimization transmission via remote control unit 20, or even in the harshest climatic environment.

According to preferred embodiment, particularly magnet of magnetic devices 80 processed and is equipped with by bar 70 by nonmagnetic substance, thereby can provide the information about the position feature of the position of bar 70 and switch element 2.For this reason, shown in Fig. 5 A, at least one transducer 82, preferred hall effect sensor, even MEMS or other transducer also can, be assembled into towards magnet 80, so that directly detect in the remote control unit 20 information about the angle position of drive link 70.Be passed to printed circuit board (PCB) 23 for analysis by transducer 82 detected signals, so that provide the ON/OFF signal.Therefore, with the information that is obtained near the trip(ping) bar 7 of switch element 2 as far as possible, promptly more reliably and to common auxiliary member module 12 _iThe information of the less sensitivity of the magnetic dispersion that distance of living in causes (dispersion) can need not attachment device and directly supplied with via one of connection 25 that is provided with by electronic commutator.According to preferred embodiment, magnet 80 is embedded into, and particularly is embedded in the suitable layout 78 of drive link 70 by force, and said magnet 80 is processed by neodymium/iron/boron alloy and is the cylinder that for example has the 5mm diameter.

Magnet 80 preferred fit become to make its edge-perpendicular in transducer 82; Promptly; Shown in Fig. 5 A, hall effect sensor 82 roughly is orthogonal to the axis at the two poles of the earth of the magnet that moves along magnetic field line B, the sense of enhancing detection thus; So in the stroke α of hall effect sensor 82, the difference of deviation less (less than 1.5mm) between the position of drive link 70.When magnet movement exceeds the INTRM intermediate point on surface of hall effect sensor 82; Transfer between the magnetic field line B is completely; And transducer 82 can detect magnet 80 and whether be positioned at its right or the left side, and the inner a large amount of electrical interaction of pipe shell 21 not.By means of this optional way, thereby transducer 82 can be arranged near magnet 80, and leaves drive link 70 particularly less than 2mm, and does not influence mensuration resolution.

Position transducer 84 also can be assemblied in the height place of the base portion 53 of handle 50, to detect the position (also seeing Fig. 1) of handle.This association thereby can give the information of signal/fault type, thus have and aforementioned identical advantage.The measurement in the time interval between the switching of the switching of drive link 70 and handle 50, tripping operation in the time of in fact can distinguishing electric fault and hand trip(ping).People's interference makes

handle

5,50 about 20 μ s setting in motions before trip(ping) bar 7 rotates, so drive link 70 makes bar 70,7 about 4ms of motion before handle 5,50 motions in view of hot type, magnetic-type or differential type tripping operation.

According to the advantageous embodiment shown in Fig. 5 B; Two

transducer

84A, 84B are arranged to have the angular deflection β ' less than the motion β of handle 50 particularly, for example about the movement angle β of handle 50 to the separated time symmetry so that measure the detection of more reliable, as to make handle 50 extreme position and the open position of contact 4 and the detection of make position and carry out with reliable mode.This optional way also may be used on the

magnetic devices

80,82 of trip(ping) bar 70, though its motion is less.Use a plurality of

transducer

82,84, particularly in the situation of three or more a plurality of transducers; In order to make power consumption minimum; First sensor 82; A transducer that particularly relates to the make position of drive link 70 can be supplied with the electric current of pulse or non-pulse, and other transducer is only just supplied power when microprocessor detects the variation of state of first sensor 82.

In a preferred embodiment, as the trip(ping) bar 7 of switch element 2, the drive link of remote control unit 20 70 rotates around pivot pin 77, with the disconnection of the contact 3 of occupying circuit breaker 2 or two remarkable positions of closure state, crosses over the angular travel α of about 20 degree.In order to limit the power that is applied on the drive link 70, drive link 70 is carried out balance, make the center of gravity of drive link 70 roughly be positioned on its pivot center 77.Therefore the influence of the mechanism of 70 pairs of auxiliary members 12 of drive link and the mechanism of circuit breaker 2 is zero, and additional mechanical stress is minimum, and said additional mechanical stress possibly posted the information transmission that invests between auxiliary member 12 or the switch element 2.According to preferred embodiment, preferably with the mode of integral body, bar 70 be furnished with in order to shift center of gravity, fly piece 79 towards an end 74 of bar 70.Whether this structure can be adjusted according to the existence of size, free space and magnetic devices 80, so that when keeping center of gravity near pivot pin 77, be magnetic devices 80 vacating spaces 78.

For reasons of safety, indispensablely be, when carrying out the assembling of remote control unit 20, switch element 2 is in off-state, i.e. the aligned position of drive link 70, and this presets spring by means of assembling usually and realizes.According to an advantageous embodiment of the present invention; In order to limit the power that hinders drive link 70 motions; Drive link 70 be mounted to lazy formula, do not have spring and bar 70 to realize by means of locking accessory 60 in the biasing of its rigging position, said locking accessory 60 offers remote control unit 20 so that its operation is ended.Particularly, be assemblied in bias operation bar on the pivot pin 77 of drive link 70 as the calibration device.Attachment component 65 cooperations of it and locking accessory 60 are driven the formula that rotates and are moved.

Therefore remote control unit 20 provides locking accessory 60 for example in outstanding (protruding) position.In case remote control unit 20 engages with switch element 2 and auxiliary member module 12; Locking accessory 60 can be forced down; Make attachment component 65 discharge the bias operation bar of drive link 70; This bias operation bar and switch element 2 and auxiliary member module mechanical connection then, thus can realization information from circuit breaker 2 to auxiliary member 12 and reverse bi-directional.

Parallel with the information transmission of optimizing, remote control unit 20 according to the present invention also has the reaction time of optimization, particularly has high actuation speed, thereby can make handle 50 with 1200 ° of s ^-1Speeds.Particularly, between the closed effective action in trip signal and contact 4, through less than half second and time of 300ms preferably approximately.The handle 50 of remote control unit 20 is therefore by means of electromagnetic actuators 100 motions; Rather than by means of the electric rotary machine motion with about closing time of 1 to 1.2s, said electromagnetic actuators 100 is actuators that a kind of very fast, acceleration can be modulated by means of the stepping power supply.

(also seeing Fig. 3) as shown in Figure 6 substantially comprises according to the actuator 100 of remote control unit 20 of the present invention: at the coil 102 that on the sheath 104 of axis AA, twines; Be fixed to the housing 110 of the shell 21 of remote control unit 20; With the magnetic piston core 120 that can move according to the axis AA of the electric current Figure 102 along the line that flows in the coil 102.The motion of core 120 is controlled by pulse signal.When stopping, do not have electric current to flow in the coil 102, and the air-gap e between the base portion 121 of the bottom 111 of housing 110 and core 120 is in maximum, and core 120 is given prominence to and is left housings 110 at Outboard Sections 122.Signal causes that electric current flows in the coil 102, and at least a portion of the Outboard Sections 122 of core 120 moves to housing 110 inside.The Outboard Sections 122 that still is retained in the core 120 of housing 110 outsides is provided with the fixture 123 of the driving mechanism 150 that is used for fixing handle 50; Particularly; Said fixture 123 is a kind of breech locks 123; This breech lock 123 is designed to the rotary type action bars is biased to indirectly the base portion 53 of handle 50, rotatablely moves so that the linear movement of movable core 120 is transformed into the part.Yet term " pulse " should be by the broad understanding of speech: shown in further, control rule advantageous applications so that optimize the operation of remote control unit 20, particularly reduces the wearing and tearing of contact 4 to actuator 100.

According to the present invention, the electromagnetic actuators 100 of remote control unit 20 can be used for high power, and must be able to instruct four single-pole circuit breakers 2 _iWith whole auxiliary members 12 as shown in Figure 1 _i, or the closed and disconnected of the moving switch of four extreme differences of 125A.Therefore, the actuating force of required generation is big, and with regard to preferred embodiment, can reach 100daN and stroke 5mm.Yet, the volume of distributing to actuator 100 just laterally with the depth direction space with regard to maintenance limited (about 40 * 35 * 50mm).According to the present invention, therefore select to use a kind of electromagnet 100, but so that utilize the surface of magnetized substantially with rectangular core 120.Housing 110 also has general rectangular formula parallelepiped shape, in addition, the axis AA of actuator 100 with respect to the panel deflection of shell 21 so that utilize available space, for example with respect to the angle γ of 4 ° of vertical directions.

In addition, consider suffered strong jarring under each attraction, selected the core 120 processed by agglomerated material, make performance can not weaken and optimize durability in time.Such material provides other advantage, and the fact is that such material can produce the fixture 123 that is used for fixing core 120 with integral way when carrying out sintering operation.Further advantageously, the edge 124 of core 120 has carried out passivation preventing any infringement, and according to preferred embodiment, the edge 124 of the AA that parallels to the axis has matrix.

Because the stress that electromagnetic actuators 100 absorbs is big, housing 110 also plays a part fixed coil 102.Housing 110 comprises particularly: be parallel to bottom 111 and roughly be orthogonal to second end wall 112 of the axis of movement AA of core 120; Second end wall 112 is provided with porose 113; The size in this hole 113 can let core 110 pass but less than the occupied area of coil 102, make coil 102 be blocked between the diapire 111 and said wall 112 of housing.Advantageously, the outward flange 114 of second end wall 112 of housing 110 is cut, thus the amount of limiting material and be the passage vacating space (see figure 3) of the driving mechanism 150 of handle 50.The assembling of the different parts of actuator 100; With self shape of housing 110 than complicated; According to the present invention; Housing 110 is preferably formed by two symmetrical parts 110A, 110B, said two symmetrical parts 110A, 110B process by agglomerated material and by means of the height place pinching of diapire 111 on the extension 106 of the plasticity sleeve 104 of coil 102 hard spot (hard-point) and be fixed to each other.Except the simplification of making, it is cheap that this solution is proved to be, and the work of the housing that has prevented to be processed by the folding sheet metal caused performance of hardening is cut down.

In order to optimize the fixing of coil 102, the sheath 104 that coil 102 is installed the place also stops coil 102 on the face perpendicular to the axis AA of coil 102.Sheath 104 also longitudinally 108 extends to be assemblied in the access opening 113 at the height place of second wall 112 of housing 110.Fixing between two part 110A of housing, 110B, this optional way has guaranteed that minimal distance of separation between housing 110 and the core 120 is to be used for the Optimizing operation of actuator.Advantageously, sheath 104 is processed by having certain thickness rigid thermoplastic material, and this thickness just in time is enough to core 120 is separated with housing 110 so that core 120 can slide, the power that while sheath 104 has maximum magnetic flux and is used to make the maximum of core setting in motion.

By chance, more than technical selection cause the performance relevant with institute's generation power of core 120 to go wrong with speed, for example the fatigue of the diapire 111 of housing 110 possibly arrive the degree of breaking.At end of travel, the air gap distance e between housing 110 and the core 120 levels off to zero, and this causes the acceleration of core 120, and this acceleration can cause fierce jarring.According to the preferred embodiment of the present invention, except that the adjustment of control rule, vibration absorber 115 is assemblied on the diapire 111 of housing 110 towards core 120, and said vibration absorber 115 is for example processed by nitrile (nitrile).Except that shown in other optional way also passable, particularly, the assembling vibration absorber forms the wall of housing, and can be by means of driving core at end of travel and with respect to all the other housings motions.Various replacement schemes shown in the French patent application number FR 0807163 can be conceived.

In addition, the base portion 121 of core 120 self is a hollow, so that air is added in the magnetic flux circuit, reduces the magnetic force at end of travel thus.Advantageously; Lateral recess 125 is a hollow in core 120; End so that keep direct core 120/ housing 110 cards of end of travel, thereby restriction is applied to the power on the vibration absorber 115, this vibration absorber 115 is contained in the recess 125 fully; Be in final compression position, so that can in surpassing 40000 operations, bring into play function.Recess 125 is preferably processed the direction that is orthogonal to breech lock 123, and this makes and utilizes agglomerated material and single shaft easier to the manufacture process of pressurization.Particularly, recess 125 is an essentially rectangular, has surperficial S ₁₂₅And degree of depth h ₁₂₅, said concave depth is no more than the still length h in housing 110 of core 120 along the axis AA of core 120 ₁₂₀-h ₁₀₈-h ₁₂₂.

Consider the surperficial S of core 120 ₁₂₀, therefore, the power F of the maximum of actuator 100 _MaxModulated in the motion process of core 120, thus the acceleration of core 120 reduced.In this way, when not having recess 125, the theoretical velocity of core 120 is tending towards infinitely great when air-gap e goes to zero, yet recess 125 is by means of producing S ₁₂₅* h ₁₂₅The air-gap of volume and this action is slowed down.Deceleration parameter Δ F can be calculated by formula:

(1), ΔF = \frac{\frac{S_{125}}{e^{2}} - \frac{S_{125}}{{(e + h_{125})}^{2}}}{\frac{S_{120}}{e^{2}}}

It may be noted that thus as volume S than air-gap ₁₂₀* e is because the little value S of the air volume that increases ₁₂₅* h ₁₂₅, when air-gap e is big, be insignificant to the influence of actuation force F.Therefore actuator 100 applied forces can not be cut down when motion initial.On the other hand, when air-gap went to zero, said volume was about no longer can ignoring each other, and when activating the end, said power possibly reduce about 15% to 20%.Said recess 125 can have another shape except that above-mentioned; This solution of recess 125 provides the two-fold advantage that increases air-gap e and produce saturation effect in the periphery of core 120; Slow down thus speed when activating the end is particularly after the resistance of the switching mechanism 3 of circuit breaker 2 has begun to descend (Fig. 2), promptly particularly; In a preferred embodiment for about 12 millimeters total kilometres when air-gap e is less than or equal to 1mm, this determines preferred air volume.In fact advantageously, when the expectation speed-down action, the volume of recess 125 is roughly corresponding to air-gap e * S ₁₂₀Volume.

More accurately, if the expectation from corresponding to air-gap e less than threshold value e _s(e for example _s=1mm) moment slows down to the predetermined stroke of core 120, and the additional volume of the air that is provided by recess 125 must become significantly, i.e. S ₁₂₅* h ₁₂₅>=1/2 e _s* S ₁₂₀, and e preferably approximately _s* S ₁₂₀Such volume.More generally, the volume that has of recess 125 half the more than or equal at the volume of the half trip of core 120 or 3/4ths air-gap e of stroke place.The volume of recess 125 is preferably greater than or equals 3/4ths or the volume of five/four-stroke place air-gap.

The height h of recess 125 ₁₂₅And the surperficial S of the relation between the width with regard to itself depending on that vibration absorber 115 is required ₁₂₅With make simple and easy.Especially, importantly have enough metal qualities and suitable solidity for core 120.Regardless of the position (promptly comprise yet and be in initial position) of housing 110 SMIS 120, recess 125 does not pass core 120 along axis AA.Advantageously, concave depth h ₁₂₅Length h less than core ₁₂₀-h ₁₂₂Half the, and the cross section of the AA that parallels to the axis of preferred recess 125 is that the ratio of the length of side was less than 1: 2 general square shape or rectangle.

Particularly, according to the present invention, pass through e=11mm to 12mm (11.7mm) and section S by core 120 motions that 0.45% iron/phosphorus is processed ₁₂₀Be 270mm ²To 300mm ², said cross section is approximately 280mm particularly ²(20.6 * 13.6).4.8mm the housing of thickness can be processed by the steel with identical sintering property.Coil preferably includes the 640 circles coiling of pitch 2 * 18mm, diameter 355 μ m.When the stroke of electromagnet 120 residue 1mm, promptly roughly its amount of movement 4/5 after, the effect of recess 125 is desired especially, so the size of recess 125 is 2 * 123.6mm ², or 1.5＜h more generally ₁₂₅＜3mm, 62mm ²＜S ₁₂₅＜S ₁₂₀, and vibration absorber 115 has the height of 4mm.

In addition; When protecting device and auxiliary member to pass through their energy point of release; The Outboard Sections 122 of core 120 is arranged in standing finish 123 belows to this mechanism and is in active position at housing 110, and also attenuation is to reduce actuator 120 in the terminal performance of movement travel.Particularly, form double inclined plane 126.

Electromagnetic actuators 100 is used to make handle 50 to turn to open position from make position.For this reason, meaning property as shown in Figure 6 illustrates with shown in Figure 7, and the base portion 53 of handle 50 is connected to the arm on the fixture 123 that is hinged on piston core 120 by means of driving mechanism 150.Particularly, the breech lock 123 with about 12 millimeters strokes joins the first arm 151 or action bars to, and the pivot 152 that makes it center on the shell 21 that is fixed firmly to unit 20 rotates.The pivot 152 of action bars 151 is preferably placed at an end, and the fixing point 153 that is fixed to breech lock 123 roughly is positioned at the center of the first arm 151.Particularly, sketched the contours of by pivot 152 two sections, fixing point 153 and the other end 154 residing ratios are greater than 4/5.In a preferred embodiment, action bars 151 is processed by the sheet metal of folding cutting and is comprised: supply hole that the sintered type breech lock 123 of core 120 passes through and for example through forcing to embed the fixation kit fixed with bar 153.Action bars 151 joins bar 160 at its free end 154, though the axis of movement AA of bar 160 and core 120 has angular deflection, bar 160 is roughly parallel to the axis of movement AA motion of core 120.The stroke of bar 160 is 16.6mm preferably approximately.In order to realize regulating (literary composition of also seeing after), bar 160 is bonded into rotation relatively freely on one section limited distance, for example ends a segment distance of restriction by means of card.Here again, fixing by means of advantageously realizing with engaging of steel pole 155.

Because electromagnetism 100 is unidirectional pulse actuators, at position of rest (seeing Fig. 7 A), promptly when electric current in coil 102, do not flow and core 120 be in " on " during the position, handle 50 remains on the position that is driven and arrive.Connecting between handle 50 and the driving mechanism with two arms 150 is preferably separable, and bar 160 only engages and is used in the stroke of motion process at it of electromagnet 100, handle 50 being activated.Particularly, bar 160 is via layout 55 cooperations of an end pieces 161 with the base portion 53 of handle 50.Because handle 50 is provided with base portion 53 (see figure 4)s that are two parts of skew along pivot center 52; The end pieces 161 of drive rod 160 preferably is the form of cross bar (cross-piece), saidly sets the form that is rendered as the guiding groove 55 on the annex 56 that is integrated into base portion 53 and roughly at axis 52 middle parts.When actuator 100 was got back to its initial position of rest, therefore handle 50 kept putting in place.Action bars 151 preferably is provided with the device that it is biased to its initial position, and for example at its torsionspring 156 at height place of pivot center 152, so that the driving mechanism 150 of handle 50 is monostable, handle 50 just itself has two stable positions.

Be assemblied on the switch element 2 for resetting and working as remote control unit 20, the position of handle 50 is corresponding to the open position of contact 4, and core 120 is outstanding from housing 110.According to the present invention, but this replacement position is the initial position of second end 161 of contact lever, and is not pressed on the groove 55 of handle, sees Fig. 7 A.Said pulse signal produces advancing by leaps and bounds of core 120, follows the corresponding sports of the free-ended cross bar 161 of bar 160 simultaneously, and the advancing by leaps and bounds of said core 120 applies pressure to the groove 55 of handle 50 so that handle 50 turns to the make position of contact 4, sees Fig. 7 C.Advantageously, driving the end, handle 50 runs into the card that is formed by shell 21 to be ended to ensure the closure of contact 4.Yet, the power that will provide in order to reduce, the end of travel of core 120 is also put corresponding to the card stop bit between core 120 and the housing 110, i.e. zero air-gap e.A kind of so hyperstatic situation implements very complicated, and it is very unreliable to become in time on earth, and makes that the joint that electromagnetic actuators 100 moves very soon and their opposing card ends is therefore very fierce.

In order to alleviate this problem, there is the different alternative way.Provable, do not considering the particularly differential auxiliary member 12 of other auxiliary member 12 ₁This fact of case of control susceptible under, in circuit breaker 2 through after the stop of handle 5 through slowing down and/or the stroke of restriction core 120 stops the driving of handle 5, this is very insecure after the operation of number of times necessarily.Stop that handle 50 is in the position, a place that compresses shell 21 and produces stress and power, this situation has the tendency of the operation of infringement actuator 100.According to the present invention, actuating mechanism 100,150 is formed device 162 by the driving mechanism 150 of handle 50 via the spring that can absorb dynamic and/or static stress in the terminal indeterminate position of the closing stroke of contact and eliminates.Device 162 preferably is positioned on second arm 160 of driving mechanism 150, and said second arm 160 comprises relative to each other movable two part 160A, 160B.Its length reduces in case stress takes place, and for example from 1.5 to 2mm, but the device 162 of types of springs is biased to extended position with bar 160, up to threshold value.

Particularly, if the rigidity of spring 162 is less than the required power of driving handle 50 when activating beginning, spring 162 is setovered by means of the motion of core 120 and the free end 161 of bar 162 and handle 50 do not move (Fig. 7 B).The biasing of spring 162 make it rigidity greater than actuating force after a while, bar 160 just move and apply pressure to handle 50 so that handle 50 rotate around its pivot 52.At the end of travel place of core 120, be stored in energy in the spring 162 and can be used to desirably the card stop bit that stroke with handle 50 extends to it and put (Fig. 7 C).Perhaps; If forming device 162, spring has the rigidity bigger than the actuating force of handle 50; Bar 160 just direct motion from core 120 beginning driving handle 50 formula that rotates is moved; And at the end of travel place of handle 50, spring forms device 162 and is designed to store the energy that end of travel disposed until core 120.

According to the structure of protection system 1, even handle 50 motion and make the closed power in contact 4, actuating mechanism 150 in fact is in a kind of situation or the another kind of situation in the above-mentioned situation, or even is in the combination of two kinds of situation.And; Because the stroke that reduces relative to the earth between two part 160A of bar, the 160B (approximately 1.5mm) and a spot of free space; Apply prestressing force so preferably spring is formed device 162; So that ensure to be used for the enough power of this little motion in the closing stroke end, thus produce dual contact and on the front panel 26 of housing 110 or shell 21 no any stress.

Said actuating force does not preferably directly act on spring from action bars 151 and forms on the device 162.The 160A of first of bar comprises the chamber body 163 that is used for telescopic second portion 160B, and telescopic second portion 160B receives chamber body 163 guiding translations, and can slide with respect to chamber body 163 in the two ends of telescopic second portion 160B.

Therefore this solution of slip pole 160 means in remote control unit 20 according to the present invention; The structure of the structure of circuit breaker 2 and remote control unit 20 does not receive owing to the indeterminate any static state that causes and dynamic strain, has reduced the wearing and tearing that the mechanism of mechanism and the switch element 2 of remote control unit 20 causes because of fatigue thus considerably.Therefore the operating reliability of unit 20 can extend to 20000 operations of as many as.This optional way can also make whole kinematics stroke be able to use, and can realize thus the multiple structure of protection system 1 is activated, particularly the described all that structure of preamble.

Advantageously, select spring to form a kind of middle rigidity of device 162, this centre rigidity is included in protection system 1 (the single circuit breakers pole 2 of minimal construction _i) mesopodium is with the power of actuation handle 50 and in the protection system 1 of maximum structure between the required power of actuation handle 50.Particularly, recommend the prestressing force of about 50N.Consider the remote control unit shell 21 of small size, preferred bar 160 comprises at least two

springs

162 ₁, 162 ₂For assemble simple and easy with in order to optimize their size, in the preferred embodiment of the present invention, two identical springs are assemblied on the parallel fork body 164.The direction of the power of transmitting in order to optimize; Y-bend body 164 every end advantageously by they chamber body 163 the guiding of two holes and engage at one end; Engage by means of the free-ended cross bar 161 of bar 160 particularly, said cross bar 161 is designed to the cooperation that sets with the form that is groove of handle 50.

Advantageously, the 160A of rigidity first of bar comprises two parallel chambers bodies 163 that are used for respectively pitching body/spring assembly, for example is bonded on form Wall board height place, that be two rectangular parallelepiped protrusion part chambers.The outer side panel of the 160A of first of bar preferably extends beyond bottom panel, and the supporting of spring 162 fork body 164 upwards exposes to supporting bar from bottom panel.Also the heavier-duty protection can be set around the fork body of said slip.In the preferred embodiment that illustrates, one of side panel 165 of the first of bar also extends beyond supporting bar 161, so that the assembly of protecting sheathing 21 inside.This structure makes assembling easily, has optimized the available diameter and the length of spring 162 simultaneously, and the diameter of their distribution.Yet other replacement scheme also is possible, particularly relates to shape and its shape of each parts of the rigid element 160A of bar.Rigid element in order to ensure bar is got back to initial position with respect to the first arm 151 of driving mechanism 150, and further advantageously, at the device that the position assembling of fixing with action bars 151 is fit to, for example torsionspring 166.

As previously mentioned, activating the end, core 120 is returned to its initial position, and handle 50 keeps putting in place, and driving mechanism 150 gets back to upper (up position), and driving mechanism 150 no longer is fixed to the base portion 53 of handle 50 at said upper place, sees Fig. 7 D.In the situation of remote control unit 20, only carry out this sequence as the running of replacement device.The closure of Fig. 7 C is reproduced in the actuating that tripping operation is reset to handle 50 position and the core 120 of Fig. 7 A.Realize also in the situation of disconnection of circuit breaker 2 that in Long-distance Control the actuating of core 120 also needs handle 50 is rotated along other direction, promptly apply traction or at the opposite side applied thrust of the pivot pin 52 of handle 50 in the end of the base portion 53 of handle 50.Thereby, prove that additional device is necessary.

According to the present invention, assembling guidance system 170 can act on a side or the opposite side of its pivot pin 52 to guarantee bar 160, according to the position of handle 50, to carry out the closure of contact 4.Particularly, guide portion 171 is one of end cross bar 161 guide path of bar 160 or another, and bar 160 is with respect to this change of the relative degree of freedom feasible direction of action bars 151, and said guide portion 171 preferably is etched on the side panel 10 of shell 21.For with bar 161 guide path 171A, 171B one or another, rotary type V-shape portion spare 172 shown in the preferred embodiment of Fig. 9, preferably is integrated in the shell 21 of remote control unit 20.Particularly; Parts 172; For example be made of plastics, rotate and follow the motion of handle 50 around pivot 173, the base portion 53 of handle 50 comprise parts 57 can with the first arm 174 associated working of the V-shape portion spare that is in the close position 172; Make second arm 175 of V-shape portion spare " close " close passage 171A (Fig. 7 D, 9B).In this way, activating the end, the end of bar 161 is pressed on the handle 50, thereby V-shape portion spare 172 is rotated.When bar 160 was got back to initial position, handle 50 was held in place with V-shape portion spare 172.In the stroke end, because actuating mechanism 150 applied forces and second arm 175 is flexible relatively, bar 160 can be with guidance system 170 tonings (overshoot).In case guide portion 171 toning, V-shape portion spare 172 returns to its position, and the rigidity of the power of handle 50 and its first arm 175 is greater than the bias force of the spring 166 that bar is joined to action bars.Therefore bar 160 turns to second path of etched guide portion 171 slightly.

When piston core 120 activated, shown in Fig. 7 E, impel action bars 151 rotation and bar 160 translations, but etched guide portion 171 is positioned at another parts of bar 160 caster assembly therefors 50 in the pressor areas 58 of opposite side of its pivot 52 particularly on shell 21.Because the rectilinear motion of bar 160 and the combination of angular movement, therefore can in narrow passage, realize the Motion Transmission of electromagnetism 120 of a side or the opposite side of handle 50.Pressor areas 58 can be similar in appearance to above-mentioned groove 55, yet, because the required little a lot of (see figure 2)s of force rate replacement power of the disconnection of contact 4, so engaging lever 160 and handle 50 more not powerfully.Particularly, the part 161 of bar 160 can be enough to when motion begins with the cooperation on the surface that is used as cam 58 of the base portion 53 of handle, and after the energy point of release and before the utmost point position of welding, driving handle and contact are to open position.In this tripping operation action,, possibly need the spring formation device 162 of bar 160 to cause, but tripping operation is realized usually by direct rotation according to external form and required power.

In case handle is in open position, V-shape portion spare 172 just can rotate freely: Fig. 7 F (with Fig. 7 A).In one embodiment, V-shape portion spare V172 is mounted to lazy formula.When bar 160 when end-of-pulsing is got back to position of rest, the bias force of driving mechanism 150 is enough to drive the unlatching (Fig. 9 A and Fig. 7 F) of second arm 175 of V-shape portion spare 172 to closed path.Yet, preferably at the height place of V-shape portion spare 172 assembling prestressed spring 176, in the guide portion 171A of " disconnection ", the power of repulsion bar 160 is calibrated.

It should be noted that when circuit breaker 2 failover tripping operations and break off, thereby when being in outside the trip unit 20, action bars 151 non-confrontational any preventions of handle 50 being got back to the returning place force of open position of remote control unit 20.Guidance system 170 is mounted to lazy formula, and therefore handle 50 does not stress, rubs or blocks in the centre position.Therefore this solution is reliably, has small size, simple and comprise only few parts, and unlike the solution shown in document FR 2840449 or the FR 2535520.

Actuating mechanism can realize that the high speed twocouese of handle 50 drives, and does not receive stress at settling position by means of simple parts thus according to the preferred embodiment of the invention.Also advantageously, optimize the control rule of electromagnetic actuators 100, the force curve figure of the handle 5 of circuit breaker 2 as shown in Figure 2 for example impacts to protect the latter through restriction is closed with as much as possible near the closing of contact time and when breaking off in the contact accessorily.
