Abstract

The invention relates to a switching arrangement for use in gas-insulated or vacuum-insulated switchgear assemblies, comprising a drive module (6) that closes or opens electrical contacts and a base carrier module (1, 1') on which individual contact modules (2) are arranged. In view of the aim to provide a compact electromechanical switching arrangement that can be scaled and configured unproblematically using as few components as possible such that said switching arrangement is suitable for a plurality of applications, the invention is characterized in that the individual contact modules (2) are identical in construction.

Description

technical field [0001] The invention relates to a switching device for use in gas-insulated or vacuum-insulated switchboards according to the general concept of claim 1 . Background technique [0002] A typical electromechanical switchgear operates the contact system of an electrical power switch, a circuit breaker, an earthing switch or a combined circuit breaking and earthing switch in the distribution instrumentation of the switchboard. It is used in particular in the medium and high pressure ranges. [0003] High demands are placed on such a power distribution device, especially in the aforementioned areas. It must be extremely reliable and demonstrate stability against vibrations and overloads. [0004] Power distribution units must operate stably over a wide temperature range and ensure safe automatic and manual operation. The operating mode or switching state must be reliably visualized and short reaction or response times must be provided during mechanical as well...
