Abstract
The invention relates to a fuse system for a switchgear assembly, especially for a medium voltage switchgear assembly. The fuse system comprises a plurality of fuses which correspond to the number of phases, every fuse having a tripping bar that projects from the face of the fuse under the effect of the force of a spring when the fuse comes into action. A sealing body, with a spring arrangement interposed, pushes a sealing head into the interior of a receptacle receiving the fuse. A two-armed lever is received on the sealing head, one arm covering a tripping mechanism which actuates a power switch.
Claims4
A fuse arrangement for a switchgear assembly, in particular for a medium-voltage switchgear assembly, having a number of fuses which corresponds to the number of phases, each of which fuses has a tripping bar, which moves out of the front face of the fuse under the force of a spring when the fuse responds, having a sealing head, with which, with a spring arrangement interposed, a sealing body is pressed into the interior of a container accommodating the fuse, wherein a twin-armed lever is mounted on the sealing head, one arm of said twin-armed lever covering the tripping bar of the fuse and its other arm unlatching a tripping mechanism, with which a circuit breaker can be driven.
