- This transmission transmits the force introduced by the drive into the first contact piece to the second contact piece or, conversely, the force introduced by the drive into the second contact piece onto the first contact piece.
- the force occurring here is considerable.
- the attachment of the nozzle to the first contact piece is relatively simple, since the contact piece has a centrally guided arcing contact and a coaxial surrounding hollow rated current contact, in which the nozzle can be secured with a first of its two ends in a dielectrically safe manner. Since the nozzle is arranged displaceably relative to the second switching piece, the coupling of the deflecting gear on the extinguishing gas serving second end of the nozzle is more expensive, especially in this case, the gas tightness and the control of the electric field in the coupling point are observed.
- a switch of the type mentioned is described in EP 0 809 268 A2 and US 6,271,494 B1 ,

- a drive element of the deflection gear can be coupled.
- he or the end of the nozzle In order to enable the engagement of the first clamping ring, he or the end of the nozzle must be elastically deformable. However, this generally requires along the switch axis guided, affecting the gas tightness and the dielectric strength slots in the nozzle end or in the first clamping ring. Therefore, additional means, such as a field electrode controlling the electric field in the region of the coupling, are required.
- the force of the switch drive is introduced into the second contact piece and transmitted via a deflection gear and an insulating nozzle on the nozzle-carrying, counter-driven to the second contact piece first contact piece.
- an annular body 80 is arranged, which carries a drive element 51 of the deflection gear and is fastened by means of a screw connection to an outer bead of the nozzle.
- the object is to provide a switch of the type mentioned, which can be made easily and inexpensively and is also characterized by good mechanical and electrical properties.

- an annular outer groove and in an on the outer surface of the intermediate ring almost free resting resting inner surface of the support ring may be formed around the axis, an annular inner groove, wherein the two grooves are arranged and formed that at a taking place during the manufacture of the switch relative displacement of the support ring and intermediate ring along the axis arranged in the outer or in the inner groove snap ring to form a secured against axial displacement connection of support and intermediate ring in the inner or in the outer groove spreads.
- the inner surface of the support ring can run out at its end facing the first contact piece in a conically widening insertion, which reduces the diameter of the snap ring prior to its spreading in the relative displacement due to elastic deformation.
- a radially inwardly extending annular step may be formed, which is seated with an annular surface forming the step height on an end face of the insulating body provided at the discharge end of the nozzle.
- the Annular step may form a portion of the diffuser and have an inner surface flaring towards the discharge end of the nozzle.
- the intermediate ring may be formed slotted and have a predominantly axially aligned, in the manufacture of the switch spreading of the intermediate ring enabling longitudinal joint.
- the intermediate ring may be formed in several parts and have at least two by predominantly axially extending longitudinal joints separate ring parts.
- the outer profile of the insulating body may have at least one annular led around the axis increase or depression, in which a largely congruent recess or increase of the intermediate ring is fitted.
- the at least one annular led around the axis increase of the insulating body may extend along the axis over at least half of the axial extent of the intermediate ring.
- the intermediate ring can also be formed free of joints and screwed to the insulating body, wherein the screw has a molded into the inner surface of the intermediate ring internal thread and an outer thread formed in the lateral surface of the insulating body.
- the screw has a molded into the inner surface of the intermediate ring internal thread and an outer thread formed in the lateral surface of the insulating body.
- an adjoining the external thread portion of the lateral surface of the insulating body may be formed an annular guided around the axis bead which is snapped into an inner groove formed in the inner surface of the intermediate ring.
- a gap-free field electrode comprising the intermediate ring can be molded into the support ring or attached to the support ring.
- a comprehensive seal the support ring may be attached to protect the rated current contacts of the two contact pieces before the action of arc gases.
- high-voltage switch is designed as a circuit breaker and includes a filled with a compressed insulating gas, such as based on sulfur hexafluoride or a sulfur hexafluoride gas filled and largely tubular shaped housing 10 and a housing 10 received, largely axially symmetric shaped contact arrangement with two along an axis A relative mutually displaceable switching pieces 20 and 30th
- the contactor 20 has in coaxial arrangement a hollow arcing contact 21 and a hollow arcing contact surrounding the hollow rated current contact 22, whereas the contact piece 30 in a coaxial arrangement includes a designed as a pencil arcing contact 31 and a surrounding the arcing contact 31 hollow rated current contact 32.
- the contact piece 20 is guided in a gas-tight manner along the axis A in a fixed, metal hollow body 40 and is connected via a hollow contact carrier 23 of the arcing contact 21 with an insulator, not shown, located at ground potential drive D of the switch.
- the hollow body 40 includes an axially aligned, the rated current contact 22 coaxially comprehensive, fixed hollow cylinder 41 which is bounded by a fixed cylinder base 42 along the axis A to the left.
- a fixed cylinder base 42 along the axis A to the left.
- an opening is provided, in which the hollow contact carrier 23 of the arcing contact 21 is mounted gas-tight while maintaining its axial displaceability.
- a sleeve 24 is fixed, which at its the switching piece 30 end facing an insulating material, such as PTFE, containing and the arc contact 21 surrounding auxiliary nozzle 52 carries.
- an insulating material such as PTFE
- a radially outwardly guided wall 25 At its end facing the drive D is a radially outwardly guided wall 25, on the outer edge of the rated current contact 22 is fixed.
- the switch piece 30 facing the end of the rated current contact 22 carries on its inside a hollow, typically containing PTFE insulator 51, which has a constriction 53 and at least one adjoining the constriction portion of a diffuser 54 of a nozzle 50.
- the sleeve 24, the wall 25, the rated current contact 22 and held in the rated current contact 22 end of the insulating body 51 define a heating volume 60 for receiving hot, ionized gas, which is formed by a switching arc resulting from the opening of the switch.
- the heating volume 60 communicates via a limited by the insulating body 51 and the auxiliary nozzle 52 heating channel 61 with one of the bottleneck and the diffuser of the nozzle 50 radially and the two open arcing contacts 21 and 31 axially limited, the switching arc receiving arc zone 62.
- a metal annular body 70 is arranged, which is positively connected to the outer profile 55 having an insulating body 51.
- the hollow cylinder 41, the cylinder bottom 42, the contact carrier 23 and the wall 25 of the sleeve 24 define a compression space 43 of a piston-cylinder compression device with a formed by the parts 23, 41 and 42 fixed hollow cylinder and one of the wall 25 and formed by the Drive D moving piston.
- the compression space 43 communicates via a arranged in the wall 25 check valve 26 with the heating volume 60, if the pressure in the compression chamber 43 is less than in the heating volume 60. If the pressure in the compression chamber 43 when closing the switch is less than the filling pressure of the insulating gas in the switch housing 10, fresh insulating gas is conducted from the switch housing 10 into the compression space 43 via a non-illustrated, arranged in the cylinder bottom 42 check valve.
- Gas stored in the heating volume 60 and in the compression space 43 is guided into the arc zone 62 when the switch is opened by the heating channel 61 and inflates the switching arc so that, as the current to be cut approaches a zero crossing, ionized arc gas passes through the discharge opening of the nozzle 50 and through the hollow space Contact carrier 23 is removed from the arc zone 62.
- the reference numeral 80 denotes a stationary mounted deflection of the switch.
- This gear includes two fixedly mounted gears 81, which engage on the one hand in one of two racks 82.
- the racks 82 are each integrated on one of two oppositely arranged surfaces in a trained as a rod 83 and rigidly connected to the arcing contact 31 output member of the deflection gear 80.
- the gears 81 each but also in one of two racks 84, which are arranged axially displaceable opposite to the rod 83.
- the racks 84 are rigidly connected to the ring body 70.
- the annular body 70 is positively connected to the insulating body 51, and since the drive D of the switch via the contact piece 20, the insulating body 51 and the annular body 70 transmits power to the racks 84, they act as a drive element of the reversing gear 80th
- the deflection gear can also be designed as a lever mechanism.
- the force deflection is then by a fixed, two-armed Reached lever on which one arm is typically articulated as a drive element and on the other arm typically acting as a driven element of the deflecting rod.
- the switching piece 20 driving force can also be introduced via the reversing gear 80 in the contact arrangement of the switch.
- the reversing gear 80 for example, designed as a rack and pinion
- the rod 83 of a in Fig.1 Accordingly, the racks 84 then act not as an on, but as an output element of the deflection gear 80 and transmit driving force through the nozzle 50 to the contact piece 20.
- the drive D resp. D apply the force for accelerating the switching pieces 20, 30, the nozzles 50 and 52 and the deflection gear 80 and for compression of the insulating gas located in the compression space 43. Since considerable forces are transmitted via the nozzle 50, the positive connection of the insulating body 51 with the annular body 70 should be extremely stable.
- the off Fig. 2 apparent ring body 70 formed in several parts and has - with respect to the axis A - in concentric arrangement a positive connection to the insulator 51 producing intermediate ring 90 and a pushed onto the intermediate ring 90 and the form-fitting locking support ring 100 for attaching the attached as or output element of the Deflection gear 80 acting racks 84.
- the intermediate ring 90 is made of a hard and elastically well deformable material, typically a steel, such as a spring steel.
- the positive connection to the insulating body 51 is achieved by a molded into the inside of the intermediate ring 90 inner profile 91, which engages in the outer profile 55 and so by positive locking a secured against axial displacement connection of insulating body 51 and intermediate ring 90 allows.
- the rigid ring, preferably made of steel, support ring 100 is pushed onto the intermediate ring 90.
- the support ring 100 can be connected much easier with the intermediate ring 90 as the intermediate ring with the insulating body 51 and can, while maintaining a good power transmission in the axial direction and about the axis A pivotally mounted on the intermediate ring 90th be stored.
- this pivotal mounting switch parts can be easily adjusted in the manufacture of the switch and easier to interconnect.
- the side facing away from the racks 84 surface of the support ring 100 can be designed as a joint-free field electrode which shields the triple formed by insulator 51, ring body 70 and insulating triple point electrically particularly effective and prevents unwanted elevations of the electric field on the surface of the insulator 51.
- the support ring 100 supports the intermediate ring 90 radially outward and thus prevents widening of the intermediate ring 90 and thus also a reduction or cancellation of the positive connection.
- annular outer groove 92 is formed in the outer surface of the intermediate ring 90 guided around the axis A. This groove is used to receive a snap ring 110. The snap ring spreads after insertion into the groove 92 and is then fixed in the axial direction in the groove 92. In a resting on the outer surface of the intermediate ring 90 inner surface of the support ring 100 is guided around the axis A, annular inner groove 101 is formed.
- the support ring 100 When manufacturing the switch, the support ring 100 is pushed with its end remote from the discharge end of the nozzle 50 on the already arranged on the insulating body 51 intermediate ring 90.
- the inner surface of the support ring 100 extends at the end to be pushed into a conically expanding insertion profile 102.
- the diameter of the snap ring 110 is therefore reduced when pushed by elastic deformation. As soon as the snap ring lies over the inner groove 101, it snaps into its groove while enlarging its diameter, thereby securing the support ring 100 against axial displacement.
- the snap ring 110 can first be spread in the inner groove 101 and then the support ring 100 are pushed with the spread in the groove 101 snap ring 110 on the already arranged on the insulating body 51 intermediate ring 90, wherein the axially fixed in the inner groove 101 snap ring 110 in the Outer groove 92 snaps and thereby secures the tag ring against axial displacement.
- a radially inwardly extending annular step 103 is formed, which has a height of this stage defining annular surface 104.
- This stage is arranged so that an end face 56 of the insulating body 51 provided at the discharge end of the nozzle 50 is seated on the annular surface 104 of the annular step 103 when the snap ring 110 snaps into the internal groove 101.
- annular step 103 advantageously forms at the same time a section of the diffuser 54 and has an inner surface 105 flared toward the discharge end of the nozzle 50.
- the intermediate ring 90 is formed slotted and has a predominantly axially aligned, from Fig.2 apparent longitudinal joint 93.
- the intermediate ring is spread open transversely to the longitudinal joint 93 and subsequently spread in the outer profile 55. The spreading process can be omitted if the intermediate ring 90 is formed in two or more parts and has one of the number of ring parts corresponding to the number of longitudinal joints, which allow a direct insertion of the ring parts in the outer profile 55.
- the outer profile 55 of the insulating body 51 at least one annularly guided around the axis A increase 57 or recess 58, in which a largely congruently formed recess 94 or increase 95 of the intermediate ring 90 is fitted.
- the outer profile 55 by a plurality of elevations 57th and recesses 58 caused comb-like structure. Because of this structure, the force to be transmitted is uniformly introduced via the outer profile 55 into the insulating body 51.
- the intermediate ring 90 may also be formed without joints. As Figure 4 can be removed, the intermediate ring is then bolted to the insulating body 51.
- the screwing in this case has a the inner profile 91 corresponding and also molded into the inner surface of the intermediate ring 90 internal thread 91 'on.
- an external thread 55 ' is screwed, which is formed according to the outer profile 55 in the lateral surface of the insulating body 51.
- An otherwise according to the embodiments of the Figures 2 and 3 trained support ring 100 can then be axially fixed as described above with the aid of the snap ring 110 which is inserted into the grooves 92 and 101.
- the support ring 100 comprises the intermediate ring 90, the support ring is formed without joints and is also provided with a surface electrode acting as a smooth surface.
- the support ring 100 therefore prevents expansion of the slotted formed intermediate ring and therefore holds the multi-part intermediate ring firmly together. At the same time it covers all longitudinal joints of the intermediate ring, whereby an influence of the intermediate ring 90 is suppressed on the control of the electric field acting in the switch.
- the field control is - as in the FIGS. 2 to 4 shown - achieved by a molded directly into the support ring field electrode 106, but can also by a Figure 5 apparent, attached to the support ring 100 hollow field electrode 106 'can be achieved.
- the use of such a field electrode reduces the moving mass in a switching operation and accordingly reduces the size of the drive D respectively. D '.
