Embodiment Construction

[0021] 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 fastened. To this end, a transversely extending fastening beam 4 with fastening holes is used for screwing the pole head part 3b. In addition, the fastening beam 4 has through-openings 5 ​​through which fastening screws for vacuum switching tubes 6 as switching tubes on the pole part 3 b of the input 3 can pass. The vacuum interrupter tube 6 is composed of a hollow cylindrical ceramic housing 7, which is composed of two parts, which are connected to each other in the center and form an intermediate flange in the middle. On the end side ceramic housing 7 through 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 v...

Abstract

In order to provide a switch pole (1) for interrupting an alternating electrical current with a supporting frame (2), which is manufactured from an insulating material, and an interrupter (6), which extends in a longitudinal direction within the supporting frame (2) between an input connection (3) and an output connection (8) and is designed to interrupt the alternating current between the input connection (3) and the output connection (8), the input connection (3), the output connection (8) and the interrupter (6) being held by the supporting frame (2), which switch pole has a supporting frame whose insulating capacity can be matched in a simple manner to the requirements placed respectively on the switch pole (1), the invention proposes that the supporting frame (2) has latching means (17, 26) for accommodating additional insulating parts (18, 19),; with which the insulating capacity of the supporting frame (2) is increased.

Description

technical field [0001] The invention relates to a switching pole for interrupting an alternating current, which has a support frame made of insulating material and a switching tube extending longitudinally inside the support frame between an input and an output for interrupting the input The AC current between the terminal and the output terminal, wherein the input terminal, output terminal and switch tube are fixed by the support frame. Background technique [0002] Such a switching pole is known from US 2001 / 0025829 A1. The switching pole disclosed there has a support frame made of insulating material for holding a vacuum interrupter extending in the longitudinal direction between the input and the output. The support frame is used for insulatingly holding the connector and the vacuum interrupter which are at high voltage potential during operation of the interrupter. The known switching pole has the disadvantage that during operation the support frame has only limited i...
