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] FIG. 1 shows a perspective view of a first exemplary embodiment of a switching pole 1 according to the invention. 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. The ceramic housing 7 is closed at the end by a metal cover, which cannot be seen in FIG. 1 , so that a vacuum-tight housing is formed. On the upper side of the vacuum switching tube 6 in FIG. 1 a fixed contact pin protrudes from the upp...

Abstract

In order to provide a fixing device (9) for fixing the switch tube (6) in the support frame (2) of the switch pole (1), the fixing device has a fixing part (20) with a through hole (22) ), a flange part (21) fixedly connected with the fixing part (20) and a support frame fixing device (10) for installing the fixing device on the support frame (2), the fixing part is used for abutting against On the end face of the switching tube (6), the flange part at least partially surrounds the outer contour of the end face, with this fastening device, a compact structural form of the switch can be achieved while maintaining the same operating voltage in the structural form. Higher operating voltages can be achieved under the same conditions. The invention proposes a field control element (20, 24) for controlling the electric field, which is electrically connected to the switch tube (6) during operation. A component of (6) is connected, and this component is at a high voltage potential during the operation of the switch tube (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...
