Abstract

A switchgear driving arrangement includes a transmission element which penetrates a wall of a housing. The transmission element is guided in a linearly movable manner in such a way as to be supported on the wall. A first guide bearing is located inside the housing. A second guide bearing is located outside the housing. An electrical switchgear is also provided.

First claim

The invention claimed is:

1. A switchgear drive arrangement, comprising:
a housing having a wall, said wall having a reversibly deformable section;
a guide bearing having a bearing sleeve, said bearing sleeve engaging around said reversibly deformable section;
a transmission element for transmitting a movement through said wall of said housing, said transmission element being guided and supported for linear displacement on said wall of said housing and said transmission element being displaceable in sliding contact with said bearing sleeve and being supported for linear movement by said bearing sleeve;
said bearing sleeve protecting said reversibly deformable section and said transmission element against external mechanical influences; and
a spacer disposed between said bearing sleeve and said reversibly deformable section along at least part of a length of said reversibly deformable section.

2. The switchgear drive arrangement according to claim 1 , wherein said transmission element is guided and supported within said housing for linear displacement.

3. The switchgear drive arrangement according to claim 1 , wherein said transmission element is guided and supported outside said housing for linear displacement.

4. The switchgear drive arrangement according to claim 1 , which further comprises a phase conductor of a switchgear, and a first guide bearing disposed on said phase conductor.

5. The switchgear drive arrangement according to claim 4 , which further comprises a fluid-tight section for closing an opening in said wall, and a second guide bearing guiding said fluid-tight section.

6. The switchgear drive arrangement according to claim 5 , wherein said first guide bearing and said second guide bearing stabilize a linear movement of said transmission element in alignment with one another.

7. The switchgear drive arrangement according to claim 5 , wherein said first guide bearing and said second guide bearing are electrically insulated from one another.

8. The switchgear drive arrangement according to claim 4 , wherein said guide bearing having a said bearing sleeve is a second guide bearing.

9. The switchgear drive arrangement according to claim 1 , wherein said spacer is displaceable relative to said bearing sleeve.

10. The switchgear drive arrangement according to claim 1 , wherein said housing is a pressure vessel.

11. The switchgear drive arrangement according to claim 1 , which further comprises a switching point of a switchgear being disposed within said housing.

12. The switchgear drive arrangement according to claim 11 , wherein said switching point is at least partially supported against said housing.

13. An electrical switchgear, comprising:
switching contact pieces configured to be driven relative to one another; and
a switchgear drive arrangement according to claim 1 for driving one of said switching contact pieces.
