Problems solved by technology

However, the disadvantage of this known fixing device is that the fixing device is made of non-conductive plastics, so that a strong electric field or a high leakage current is generated at the top or corner region of the switching tube to which a high voltage potential is applied.

Embodiment Construction

[0022] figure 1 A first exemplary embodiment of a switching pole 1 according to the invention is shown in perspective. The switching pole 1 has a mechanically fixed support frame 2 , to which the pole head part 3 b of the input 3 is fixedly screwed. To this end, a transversely extending fastening beam 4 with fastening holes is used for screwing the pole head part 3b. Furthermore, the fastening beam 4 has a through-opening 5 through which fastening screws of a vacuum interrupter 6 as an interrupter at the input 5 can pass. The vacuum interrupter 6 consists of a hollow cylindrical ceramic housing 7 which consists of two parts which are connected to one another in the center of the ceramic housing forming an intermediate flange in the middle. On the end side the ceramic housing 7 consists of the figure 1 It is closed with a metal cover that cannot be seen in the middle, thus forming a vacuum-tight enclosure. exist figure 1 A fixed contact pin on the upper side of the medium ...

Abstract

In order to provide a holding apparatus (9) for holding an interrupter (6) in a supporting frame (2) of a switch pole (1) with a holding section (20), which has a through-opening (22) and is designed to bear against a front face of the interrupter (6), a flange section (21), which is fixedly connected to the holding section (20) and at least partially surrounds the outer contour of the front face, and a supporting frame fixing (10) for fitting the holding apparatus to the supporting frame (2), with which holding apparatus a more compact design of a switch can be brought about given the same operating voltage or an increased operating voltage can be brought about given the same design, the invention proposes a field control element (20, 24) for limiting an electrical field, which element, during operation of the interrupter (6), can be conductively connected to a constituent part of the interrupter (6) which is at a high-voltage potential during operation of the interrupter (6).

Description

technical field [0001] The invention relates to a fixing device for fixing a switch tube in a support frame of a switch pole, the fixing device has a fixing part with a through hole, a flange part fixedly connected with the fixing part and a The fixing device is a support frame fixing device mounted on the support frame, the fixing part is used to abut against the end face of the switch tube, and the flange part at least partially surrounds the outer contour of the end face. Background technique [0002] Such a fastening device is known from US 2001 / 0025829 A1. The known fastening device is intended to fasten a vacuum interrupter and has a disk-shaped fastening part which bears against the end face of the vacuum interrupter during operation, through which a longitudinally movable actuating rod extends. The fastening part is connected to a substantially perpendicular fastening part which, in the installed state, extends around the outer contour of the inserted vacuum interru...
