VACUUM VALVE

摘要

A vacuum valve, wherein a shunt part is disposed in a vacuum container between a movable electrode and an insulated operation rod extending airtight through the vacuum container so that the shunt part as a high-tension live part can be completely insulatedly protected and multiple units of the vacuum valves can be disposed compactly and collectively, the vacuum container together with fixed side and movable side terminals are buried in a generally rectangular mold resin insulation body, the outside profile of a switching operation device is formed in the generally same projected shape as the axially projected shape of the mold resin insulation body of the vacuum valve so as to form a generally rectangular vacuum valve assembly as a whole, and three units of the vacuum valve assemblies may be installed parallel with each other so as to form a three-phase collective type assembly, and the mold resin insulation body may be molded individually or collectively.
