Vacuum circuit interrupter

摘要

A vacuum circuit interrupter for use in a switchgear connectable to a three-phase ac power system and having for each phase a vacuum valve including a pair of separable electrodes supported within a hermetic vessel by an electrode. Axes of the vacuum valves for three phases are arranged in parallel and at apexes of a triangle. Electrically insulating barriers are disposed for supporting and electrically insulating the vacuum valve from another vacuum valve in another phase and from the hermetic vessel. <IMAGE>
