Switchgear with switching devices arranged in housings

摘要

The invention relates to switchgear assemblies having switching devices arranged in housings whose contact bolts can be deflected in a straight line and can be controlled by a magnetic drive device and are guided axially and radially by means of concentrically arranged slotted guides. The housings are formed by mutually opposite pole shells, and the slotted guides are each provided by rotating guides mounted at one end. The rotating guides each have a trapezoidal lever contour and are equipped with guide pins which extend outward and are mounted such that they can rotate in guide recesses in the mutually opposite pole shells. The rotating guides are each provided with a U-shaped bolt bearing in which a guide bolt is mounted. Switchgear assemblies such as this are used in the field of electrical power supply and distribution.
