Document Type and Number:
Japanese Patent JP6990293
Kind Code:
B2
Abstract:
The invention refers to a disconnector pole (214) for a gas insulated switchgear and a disconnector unit comprising at least two of the aforementioned disconnector poles (214). Moreover, the invention refers to a gas insulated switchgear comprising at least one aforementioned disconnector pole (214) or at least one aforementioned disconnector unit and/or a circuit breaker. The disconnector pole (214) is movable between two contact positions. Moreover, the disconnector pole (214) comprises a metallic contact device (218, 220A, 220B, 221A, 221B, 222A, 222B) to be connected to contacts in the two contact positions. The metallic contact device (218, 220A, 220B, 221A, 221B, 222A, 222B) comprises an outer surface (256). The disconnector pole (214) also comprises at least one metallic housing (219), wherein at least 50% of the entire outer surface (256) of the metallic contact device (218, 220A, 220B, 221A, 221B, 222A, 222B) is arranged in the metallic housing (219).
