Embodiment
Fig. 1 is the front view of the circuit breaking apparatus of embodiments of the present invention 1, and Fig. 2 is the stereoscopic figure that Fig. 1 is resolved into each unit.In addition, Fig. 3 be only the detection of electrical leakage unit in the presentation graphs 1, particularly dot the front view of its inner distribution state.In addition, Fig. 4 and Fig. 5 are the housings separately that unloads circuit-breaker and externally positioned type appendicle, the internal structural map that the A direction is observed from the figure of Fig. 1, in addition, Fig. 6 is a part that cuts detection of electrical leakage unit housing 33, the internal structural map that the B direction is observed from Fig. 1 figure.In addition, (a) among Fig. 4～Fig. 6 and (b) is respectively (electric leakage) tripped condition, on-state.
As shown in Figure 1, circuit-breaker 101 constitutes as follows, stacked a plurality of (under this situation being 4) one pole with the device of circuit-breaker 1 (below, be referred to as circuit-breaker 1) figure in right flank, be configured as the externally positioned type appendicle 2 of warning contact, in addition, the right flank in the figure of this externally positioned type appendicle 2, configuration has the detection of electrical leakage unit 3 of detection of electrical leakage function.The handle 11 of circuit-breaker 1 and the handle 21 of externally positioned type appendicle 2 are connected by not shown pin etc., and handle 21 links with the operation of connection (among the figure, from the downside to the upside) that utilizes handle 11 manually to carry out and disconnection (among the figure, from the upside to the downside).On the other hand, the handle 31 of detection of electrical leakage unit 3 utilizes the holding section 31a that possesses on this handle 31, engages with upside among the figure of handle 21.That is, with handle 31 when disconnecting the direction operation, handle 11 (and handle 21) is interlock with it also, but in the opening operation of handle 11, handle 31 is interlock with it, keeps being still on the on-position.Yet in the state of this Fig. 1, expression is operated and is resolved evolution to (being equivalent to simulate leakage, breaking) owing to leakage, breaking or handle 31.In addition, from this structure as can be known, among outside terminal 14a, the 14b of circuit- breaker 1,14a becomes power supply one side, and 14b becomes load one side.In addition, 33a is well-known leakage tests button, and it confirms whether the detection of electrical leakage function can operate as normal.
Below, the assembling sequence of circuit breaking apparatus 101 is described.As shown in Figure 2, circuit-breaker 1 and externally positioned type appendicle 2, the claw 22b that utilization is arranged on the matrix 22 of the framework that constitutes externally positioned type appendicle 2 fixes, as mentioned above, by not shown pin etc., will link between the handle 11,21, but this moment, for the action with the switching mechanism described later portion of circuit-breaker 1 passes to externally positioned type appendicle 2, among the connect apertures 22a on being arranged at matrix 22, embed tripping operation cam 41.So, since relative with connect apertures 22a to the position on, be provided with the housing 13 of circuit-breaker 1 not shown connect apertures (with the connect apertures 12a of matrix 12 (still, because this connect apertures 12a does not use in the present embodiment, so with it stifled on) identical hole also is provided with in housing 13 1 sides), so tripping operation cam 41 engages with the switching mechanism portion of circuit-breaker 1 via this connect apertures.Thus, when circuit-breaker 1 tripping operation, can utilize externally positioned type appendicle 2 output alarms.
On the parts of having fixed circuit-breaker 1 and externally positioned type appendicle 2, utilization is arranged on the claw 32b on the matrix 32 of detection of electrical leakage unit 3, also fixed this detection of electrical leakage unit 3, but this detection of electrical leakage unit 3 is different with externally positioned type appendicle 2, also needs to be connected with main circuit.That is,, be fastened on by terminal screw 41 (with reference to Fig. 4) on the outside terminal 14b of circuit-breaker 1 utilizing the end 36a that covers its conductor that exposes 36 from the matrix 32 extended terminal covering part 32c of detection of electrical leakage unit 3.As shown in Figure 3, for the phase fault that prevents to cause by its contact, on this conductor 36 except the 36a of end, all covered by for example insulated tube, and 4 are inserted from the side of matrix 32 simultaneously, and the direction bending roughly behind 90 degree, makes it curve U-shaped in figure, after the well-known zero sequence converter 37 that runs through the leakage current that detects this circuit, be connected with outside terminal 34.As shown in Figure 2, on matrix 32, be uniformly set connect apertures 32a with externally positioned type appendicle 2,, the action of the aftermentioned switching mechanism portion of detection of electrical leakage unit 3, i.e. electric leakage action be delivered to the switching mechanism portion of externally positioned type appendicle 2 by be embedded in tripping operation cam 42 at this connect apertures 32a.This transmission be by relative with connect apertures 32a to the position on, be provided with that the not shown connect apertures (hole identical with the connect apertures 22a of matrix 22 also is provided with in housing 23 1 sides) of the housing 23 of externally positioned type appendicle 2 carries out, identical with above-mentioned circuit-breaker 1 with the transmission between the externally positioned type appendicle 2.
Yet when using this circuit breaking apparatus 101, the user connects for example power supply side line rod on the outside terminal 14a of circuit-breaker 1, connects flexible load side electric wire on the outside terminal 34 of detection of electrical leakage unit 3, and beginning is to for example bulb even load power supply.In this power supply state, under overcurrent that causes because of certain reason or the situation about flowing through by the fault current that short circuit causes, cut off circuit by circuit-breaker 1, simultaneously this cut-out is delivered to externally positioned type appendicle 2, switching mechanism portion by this externally positioned type appendicle 2 moves, carry out corresponding actions with outside terminal 24 not shown buzzer or bulbs that be connected, that for example be provided with in the place away from this circuit breaking apparatus 101, thus, the user can grasp the unusual of this circuit.In addition, in this circuit, take place under the situation of electric leakage, the switching mechanism portion of detection of electrical leakage unit 3 moves, and this action is passed to externally positioned type appendicle 2 and then passes to circuit-breaker 1, when overcurrent takes place with in the same manner, cut off circuit by circuit-breaker 1, simultaneously from the 2 output alarms of externally positioned type appendicle.In addition, in present embodiment 1, with circuit breaking apparatus 101 be called RCBOs (
rEsidual
cUrrent operated circuit-
bReakers withintegral
oThe abbreviation of vercurrent protection promptly possesses the residual current circuit breaker of overcurrent element), with externally positioned type appendicle 2 be called AL (
AlThe abbreviation of arm switch).In addition, " first, second links parts " mentioned in the claim is respectively tripping operation cam 41,42.
Because " transmission " between above-mentioned each unit is main points of the present invention, so further it is elaborated based on Fig. 4～Fig. 6.In Fig. 4 (a), as everyone knows, by making it cross the line of force along clockwise direction turning handle 11 among the figure, constitute the chain shot 151 of switching mechanism portion 15 and arm 152 with chain shot pin 153 as center of rotation, along with in figure, counterclockwise rotating, shown in Fig. 4 (b), movable contact 161 contacts with fixture 162, can power to the load.If under this closure state overcurrent takes place, though then do not describe in detail, bimetal piece 17 or electromagnet apparatus 18 move, and switching mechanism portion 15 and movable contact 161 become the position shown in Fig. 4 (a).Thereby, be embedded into the end 41a of circuit-breaker 1 one sides of the cam 41 that trips, shown in (a) is different with the position of (b), move connecting between the tripping operation.In addition, be on-state with handle 11 from Fig. 4 (b), the off-state after in figure, counterclockwise rotating, also identical with Fig. 4 (a), but on the translational speed of above-mentioned end 41a, present difference.
Utilize and should move, the end 41b that embeds externally positioned type appendicle 2 one sides is also as Fig. 5 (a) and Fig. 5 (b) shown in, and is similarly mobile at the chain shot 251 and 252 on the arm of the formation switching mechanism portion 25 of this externally positioned type appendicle 2.Its result, the movable contact 261 that is built in the formation switch 26 in this externally positioned type appendicle 2 rotates, promptly, from before with the conducting of fixture 262 to switching with the conducting of fixture 263, thus, become lighting mode change load, for example bulb of the outside terminal 24 that is connected with these fixtures 262,263.In addition, in this embodiment, because constitute so-called 1c contact, so outside terminal 24 possesses 3, but being not limited to these 3, also can be to become 1a contact or 1b contact 2.In addition, switch 27 be with the so-called auxiliary contact of the on off state of circuit-breaker 1 interlock (be called as AX (
au
xThe abbreviation of iliary switch)), no matter it be opening operation or tripping operation action, all connecing with movable contact 161 from switching.As mentioned above, only pass through the position of the handle 11 of circuit-breaker 1, can not know that this circuit-breaker 1 is disconnected operation, still has overcurrent to take place in circuit, but AL and AX are installed by on externally positioned type appendicle 2, mixing like this, can more correctly obtain the state of circuit-breaker 1, and then obtain the situation of circuit.But, about this AX, because do not have direct relation with the present invention, thus the same with the difference of the translational speed of aforesaid end 41a, all omit its detailed explanation.
On the other hand, in Fig. 6 (b), taking place under the situation of leakage current, detecting the imbalance of the electric current that flows through conductor 36 that causes by this leakage current, and this signal is being delivered to circuit part 38 by zero sequence converter 37.In circuit part 38, this signal is amplified, and its height, width and reference level are compared, if judge it is the level that has detected electric leakage, then make breaking coil 39 excitations.By this excitation, the moving iron core 39a of breaking coil 39 is attracted right in figure, switching mechanism 35 from the closure state of Fig. 6 (b) (though detection of electrical leakage unit 3 itself does not have contact, but because it makes up with circuit-breaker 1 and externally positioned type appendicle 2, so for convenience, it is called off-state or closure state) change to the off-state of (a).So the end 42b that embeds the tripping operation cam 42 of this switching mechanism portion 35 follows this conversion.
This tripping operation cam 42 is owing to have the end 42a that embeds externally positioned type appendicle 2 one sides, so follow moving of above-mentioned tripping operation cam 42, externally positioned type appendicle 2 also moves in the same manner with the tripping operation that is produced by above-mentioned overcurrent, be transformed into off-state (Fig. 5 (a)) from closure state (Fig. 5 (b)), thereby switch 26 (and 27) switches.Meanwhile, the tripping operation of the switching mechanism portion 25 of this externally positioned type appendicle 2 action is delivered to circuit-breaker 1 one sides via tripping operation cam 41, thereby circuit-breaker 1 can trip, promptly carry out leakage, breaking.
Like this, by the tripping operation action that the circuit-breaker 1 that overcurrent causes takes place, make 2 actions of externally positioned type appendicle via tripping operation cam 41, in addition, the tripping operation action of the detection of electrical leakage unit 3 that causes by taking place to leak electricity makes 2 actions of externally positioned type appendicle via tripping operation cam 42, and then make circuit-breaker 1 action via tripping operation cam 41, thus, when overcurrent and when electric leakage, can carry out circuit breaker simultaneously and the output of reporting to the police.This mainly is because each switching mechanism portion (15,25,35) utilizes tripping operation cam 41,42 to connect, and makes the structure proximate of each switching mechanism portion simultaneously, so that should tripping operation cam 41,42 shapes uncomplicated, and can easily embed.Further describe, according to the switching mechanism portion 25 with externally positioned type appendicle 2 is the center, with the switching mechanism portion 35 of the switching mechanism portion 15 of circuit-breaker 1 and detection of electrical leakage unit 3 respectively about on the mode of configuration equally spaced roughly, on the structure of each unit, particularly detection of electrical leakage unit 3, try every possible means, obtain above-mentioned effect.Thus, even the residual current circuit breaker of household small-size also can obtain the warning output of being opened circuit and being produced by it, can need monitor from afar, for example during the selection of important circuit, reduce restriction.
Circuit breaking apparatus described in the execution mode 1, under situation about for example opening circuit because of electric leakage, if user's trend possesses the scene of this circuit breaking apparatus, then be in open position (with reference to Fig. 1) by each handle (11,21,31), can learn that circuit breaking apparatus moves because of electric leakage.On the other hand, only utilize and be connected action on the profile appendicle 2, for example buzzer, can not distinguish that opening circuit of this circuit caused by overcurrent, still cause by electric leakage, but as long as special at least output is reported to the police for the leakage, breaking of foregoing circuit, in this case, can be by on above-mentioned " transmission " method, trying every possible means to make its possibility that becomes.Be illustrated as execution mode 2 with this.In addition, Fig. 7 illustrates this execution mode 2 in order to understand ground easily, and with the figure that the engaging between the chain shot of tripping operation cam and each switching mechanism portion schematically illustrates, (a) expression is used for the above-mentioned execution mode 1 of comparison, (b) expression present embodiment 2, (c) and (d) expression execution mode 3 described later.
Shown in Fig. 7 (a), at execution mode 1, be that overcurrent and electric leakage all obtain reporting to the police in the situation of output, one in the parts of the formation switching mechanism portion 25 of externally positioned type appendicle 2 is on the chain shot 251, needs the first effector 251a, the second effector 251b and transfer part 251c.On the other hand, in present embodiment 2, shown in Fig. 7 (b), remove the first effector 251a.Thus, when electric leakage, action with the tripping operation cam 42 of chain shot 351 interlock of detection of electrical leakage unit 3, be passed to the second effector 251b and chain shot 251 moves, because of the action of this chain shot 251 makes tripping operation cam 41 produce interlock via transfer part 251c, thus, circuit is cut off in chain shot 151 actions of circuit-breaker 1.On the contrary, when overcurrent, though cut off circuit by chain shot 151 actions, the action interlock of only trip cam 41 and this chain shot 151, the chain shot 251 of externally positioned type appendicle 2 keeps static.
That is, in the circuit breaker that produces by electric leakage, by the chain shot 251 actions output of reporting to the police, but in the circuit breaker that produces by overcurrent, owing to chain shot 251 is failure to actuate, so the output of not reporting to the police.Thus, because the user can be very fast determines that the corresponding actions of for example buzzer that is connected with externally positioned type appendicle 2 is a leakage, breaking, so can check efficiently or repair.With respect to the AL of explanation in the execution mode 1, the externally positioned type appendicle 2 that this and leakage, breaking are linked be called EAL (
eArth
AlThe abbreviation of arm switch), the user can make suitable selection to these AL or EAL according to situation of this circuit etc.The pin that does not need to make the handle 21 of the handle 11 of circuit-breaker 1 and externally positioned type appendicle 2 to be connected in addition, is being installed under the situation of EAL.
Below, describe as execution mode 3 with Fig. 7 (c) with (d).The characteristics of present embodiment 3 are not make circuit breaker when electric leakage takes place.At first, in Fig. 7 (c), remove transfer part 251c.Thus, in when electric leakage, though be delivered to the second effector 251b with the action of the tripping operation cam 42 of chain shot 351 interlocks of detection of electrical leakage unit 3, make chain shot 251 actions, owing to there is not transfer part 251c, the action of this chain shot 251 is not delivered to tripping operation cam 41.That is,,, do not carry out circuitry cuts only by externally positioned type appendicle 2 output of reporting to the police even leak electricity yet.In addition, owing to possess the first effector 251a of chain shot 251, so by the overcurrent output of also reporting to the police of opening circuit.
That is, this Fig. 7 (c) and execution mode 1 similarly, be can not determine to report to the police output be cause by overcurrent (opening circuit) still by (non-opening circuit) circuit breaking apparatus that cause, that carried so-called AL that leaks electricity.On the other hand, in Fig. 7 (d), though possess each parts of explanation before this on chain shot 251, promptly the first effector 251a, the second effector 251b and transfer part 251c do not have tripping operation cam 41.Thus, because the action transmission of opening circuit of circuit-breaker 1 is less than on the externally positioned type appendicle 2, so it becomes can only judge immediately that the output of reporting to the police has only been caused, carried the circuit breaking apparatus of so-called EAL by electric leakage (non-opening circuit).In a word, as mentioned above,, do not carry out opening circuit of circuit in the electric leakage output of the time only reporting to the police, therefore, this execution mode 3, be Fig. 7 (c) and circuit breaking apparatus (d) 101 be called as MCBs (
mIniature circuit
bThe abbreviation of reakers).This MCBs for following situation etc. effectively, that is, even for example leak electricity, also confirm load particularly mechanical device etc. be positioned at home, the handle 11 to circuit-breaker 1 carries out opening operation afterwards, carries out the inspection of this circuit etc., that is, be unsuitable for the situation of carrying out as soon as possible leakage, breaking etc.
More than, in the execution mode 1～3 of explanation before this, each component function of the chain shot 251 of externally positioned type appendicle 2 is as follows.
The first effector 251a: the overcurrent of accepting circuit-breaker 1 opens circuit
The second effector 251b: accept the electric leakage action of detection of electrical leakage unit 3
In addition, can utilize having or not of above-mentioned each parts or tripping operation cam 41, make up following product group.
The RCBOs of band AL: be equivalent to Fig. 7 (a) (execution mode 1)
