Example Embodiment

[0022] FIG. 1 shows a first exemplary embodiment of a switching pole 1 according to the invention in a perspective view. The switching pole 1 has a mechanically fixed support frame 2 on which the pole head portion 3b of the input end 3 is fixedly connected by means of bolts. For this purpose, a transversely extending fixing beam 4 with fixing holes is used for screwing the pole part 3b. In addition, the fixing beam 4 has a through hole 5 through which the fixing bolt of the vacuum switching tube 6 , which is the switching tube at the input end 5 , can pass. The vacuum switching tube 6 consists of a hollow-cylindrical ceramic housing 7, which consists of two parts, which are connected to each other in the center of the ceramic housing with an intermediate flange formed in the middle. The ceramic housing 7 on the end side is closed by a metal cover, which cannot be seen in FIG. 1 , so that a vacuum-tight housing is formed. In FIG. 1 a fixed contact pin on the upper side of the...

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...
