Definitions
- the invention relates to a circuit breaker, in particular a high current switch, with a pole unit with a pole head and a pole base and an interposed contact system as well as a drive unit for initiating a shift movement clock system in a moving contact of the con- least, each pole head and each pole supports the pole ⁇ unit are each attached to a support wall of the circuit breaker by means of a supporting device with two ne ⁇ by side arranged support elements.
- Such a circuit breaker is known, for example, from the Siemens publication "Siemens HG 11.11, 1999.”
- the high-current switch disclosed there as a circuit breaker comprises three pole units each having a pole head and a pole carrier, and a drive unit for initiating a switching movement into a moving contact of a contact system of the respective ones pole unit.
- each pole head and each pole supports with the interposed contact system are mounted on a retaining wall of the circuit breaker by means of two juxtaposed support members.
- two adjacent support elements are provided for pole piece and pole carrier, a ranging from ⁇ stability at by the high currents auftre ⁇ border large transverse forces on the polar units to be guaranteed ⁇ th.
- Object of the present invention is to develop a circuit breaker of the type mentioned, which in a structurally simple structure on improved egg properties in terms of stability and insulation.
- the object is achieved in a circuit breaker of the type mentioned above in that the support means comprise a single integrally formed insulating body instead of the two support elements.
- the stability of the entire assembly is also improved because can be taken up by the einstü ⁇ ckigen insulating body with its cross-section with comparatively large dimensions as ⁇ by the massive structure of the one-piece Isolierkör- pers in shear stresses higher forces.
- the support means comprises a metal retaining plate, which ei ⁇ neterrorism wall on the insulating member and on the other hand on the holding ⁇ is attached.
- a metal retaining plate is a simple way of securing the insulating Body realized on the retaining wall of the circuit breaker under distribution ⁇ ment of the mechanical stress.
- Figure 1 is a cross-sectional view of a power switch according to the invention.
- Figure 2 is a cross-sectional view of a support element of the circuit breaker of the invention of Figure 1;
- FIG. 3 is a perspective view of the support element of FIG. 2.
- FIG. 1 shows a high current switch as a circuit breaker for high current applications in a cross-sectional view.
- the circuit breaker 1 comprises three pole units for the three phases of an alternating current to be switched, of which only one polar unit is shown in FIG. 2.
- the pole unit 2 comprises a pole head 3 and a Polträ ⁇ ger 4, between which a contact system 5 in the form of a vacuum interrupter 5 for switching a current between a first terminal 6 of the pole head 3 and a second terminal 7 of the Pollusts 4 is arranged.
- a moving contact 8 the vacuum interrupter 5 is coupled via a drive linkage 9 to a drive unit 10 of the circuit breaker, wherein the drive unit 10 is designed to initiate a Wegbewe ⁇ tion in the moving contact 8 of the contact system 5.
- the pole unit 2 is secured by means of support means 11 and 12 and holding devices 13 and 14, respectively, to a retaining wall 15 of the circuit breaker.
- the support means 11 and 12 are used for electrical insulation of the pole unit 2 with respect to the retaining wall 15 and the drive unit 10 of the circuit breaker and for the mechanical stabilization of the entire arrangement.
- FIG. 2 shows a cross-sectional view of the support device 11 from FIG. 1, wherein the support device 12 has the same design.
- the support device 11 comprises a one-piece insulating body 16 with an oval formation made of cast resin, which is fastened by means of two juxtaposed screw 17, 18 on the pole unit 2 of Figure 1, and two adjacent juxtaposed screwings 19 and 20 on a metallic support plate 21st is attached, which in turn is in turn screwed by means of a fastening ⁇ supply means 22 in the form of a screw with the holding device 13 of the circuit breaker.
- the insulating body 16 has an oval cross-section with an approximately twice as long longitudinal extent as compared to its transverse extent and is also provided with on its outside circumferential ribs 23 provided, which serve to increase the tracking resistance of the insulator.
- Figure 3 shows a perspective view of the insulating body and the support means 11 of Figure 2, in which in particular the circumferential ribs 23 can be seen, as well as the attachment of the metallic support plate 21 through the screw connections 19 and 20 of the insulator. From the metal retaining plate out the screw 22 extends to attach the support means to the retaining wall of the circuit breaker.
