More Information
Summary:The present invention provides a gas-insulation switch device wherein insulation performance is improved by efficiently eliminating residual hot gas, and capable of readily achieving the shut-off requirements demanded of a high-voltage switch. In this invention, formed inside a mobile shield (23) are a compression chamber (30) on a mobile contactor base (22) side and an aspiration chamber (31) ona mobile contactor (21) side with a piston (25a) of an operating rod (25) serving as a partitioning wall. The compression chamber (30) blows dielectric gas through a communicating hole (25c), a hollowsection (25b), and an aeration hole (21a), toward an arc (40) generated between a fixed arc contactor (11) and a mobile contactor (21) by the compression of the dielectric gas within the compressionchamber due to the movement of the piston (25a) when opening the poles. The aspiration chamber (31) draws in a high-temperature gas caused by the arc (40) from a gap (31a) between the mobile contactor(21) and a mobile shield (2
