Abstract

An electrical, medium voltage, switching mechanism which includes a casing having an insulating material filling. In the casing, between a cable connection and a bus bar, a change-over switch, which can alternately switch between a phase contact and a ground contact, follows a load disconnector which is in the form of a vacuum switching tube. An axially displaceable shaft is provided which is displaceable relative to the load disconnector and is rotatable relative to the change-over switch. The bus bar passes through an insulator at right angles thereto. The associated through passage in the insulator is widened into a slot, the length of which permits the switching movements of the load disconnector. The insulator is divided into an insulator core and an insulator casing which is rotatably mounted on the insulator core. In the region of the insulator casing, the through passage is further widened into two sector windows which have an angular aperture which permits the switching movements of the rotary contact of the change-over switch. As a result, the switching mechanism has a structural form which at high operational reliability requires little space, is economical to manufacture, and can be serviced in a time saving manner.
