Abstract

An electric switching section within a metal encapsulation containing an insulating gas, for instance SF.sub.6 is disclosed. The metal encapsulation encloses at least one transformer and a vacuum switching tube for each phase. The switching tube is enclosed in part by the transformer device and has a stationary terminal. The transformer includes a cup-shaped electrode which constitutes the inner electrode of a capacitive voltage transformer. The bottom of the cup-shaped electrode is detachably connected to the stationary terminal of the switching tube and to an extension of a cable termination. The bottom of the electrode is further detachably fastened to a feedthrough plate, through which the extension passes. This arrangement in cooperation with a conventional outer electrode permits the voltage present at the vacuum switching tube to be measured in a simple manner.
