摘要： 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).

摘要： The invention refers to a circuit breaker (300A) comprising a vacuum interrupter (301) for a gas insulated switchgear. Moreover, the invention refers to a gas insulated switchgear comprising at least one circuit breaker (300A) and/or a disconnector pole. The circuit breaker (300A) has a vacuum interrupter (301) comprising a first movable contact (302), a second stationary contact (303) and a first center axis (304). Moreover, the circuit breaker (300A) comprises a first insulator (305), a contact unit (306) arranged at the first insulator (305), wherein the first movable contact (302) can be moved towards the contact unit (306) so as to be connected to the contact unit (306), an electrical conducting unit (307) comprising a first side (308) and a second side (309), wherein the first side (308) and the second side (309) are opposite to each other, wherein the vacuum interrupter (301) is arranged at the first side (308) of the electrical conducting unit (307), and a second insulator (310) wherein the second insulator (310) is arranged at the second side (309) of the electrical conducting unit (307), wherein the second insulator (310) is connected to the second stationary contact (303), wherein the second insulator (310) has a second center axis (311), and wherein the second center axis (311) of the second insulator (310) is parallel to or collinear with the first center axis (304) of the vacuum interrupter (301).
