High-voltage power switch has electrical contact assembly for generating a stream of quenching gas and compression device with piston and cylinder moving in relation to each other

摘要

A high-voltage power switch has an electrical contact assembly and a compression device (9) for generating a stream of quenching gas. The compression device has a piston (10) and a cylinder (11) that can be moved in relation to each other. The electrical contact assembly has one or more movable contact pieces, whose movement is uncoupled mechanically by the compression device in relation to the movement capability of the piston and/or the cylinder.
