Abstract

A multi-pole vacuum switch has an insulation assembly for each pole, which is composed of shell-like insulating elements. In addition to a space provided for receiving the vacuum interrupter, chambers are formed by wall sections, which are provided for receiving mechanical and electrical components of a pole unit. In particular, these electrical components are a loop-shaped, flexible strip conductor, a lever arrangement, contact springs and current transformers. Tensioning bolts which penetrate all the pole units connect the pole units to a pole block. The invention is suitable for use in vacuum power switches, in particular for low operating voltages.
