| 摘要 |
The invention relates to a two or three position switch which is arranged in an encapsulating module (1) accommodating three phase conductors (1) in a gas-insulated high-voltage switching installation. In order to facilitate assembly and simplify the design of the drive path for the switching elements (32) which are embodied in the form of cylindrical contact pieces, an insulating bar is used as a common actuating shaft, whereby one-armed levers (61, 62, 63) are secured to said bar to enable axial displacement of the switching elements. The actuating shaft is guided into case-like parts (21, 31, 41) of the phase conductors by means of bearing bushes (52, 53, 54). Said shaft can consist of two partial sections (55, 56) which are detachably connected in the area of an external phase conductor. |
