Claims

[Scope of utility model registration request]

(1) Phase-separated gas-insulated switchgear with a double busbar system, in which the high-voltage charging parts of each phase are insulated and supported with insulating spacers, and are individually housed together with insulating gas in a roughly cylindrical grounded metal container. In a gas-insulated switchgear that is connected to a plurality of external circuits, and in which the central axes of two sets of 6-phase main busbars are arranged in parallel on a first horizontal plane, the first An electric circuit extends vertically upward from each phase main bus bar of the set and the second set, and after its central axis reaches a second horizontal plane spaced apart above the first horizontal plane, it extends on this second horizontal plane. The electric circuits extending from the same phase of the two sets of main busbars are electrically coupled to each other by an intermediate conductor, and the electric circuit further has a branch electric circuit leading to the breaker by the intermediate conductor extending substantially within the second horizontal plane. An electric circuit extends vertically downward from the first external connection unit and each phase main bus bar of the first and second sets, and its central axis extends to a third horizontal plane spaced below the first horizontal plane. After reaching the third horizontal plane, the electric circuits extending from the same phase of the two sets of main busbars are electrically coupled to each other by the intermediate conductor extending on the third horizontal plane, and the electric circuits further extend substantially within the third horizontal plane. A gas-insulated switchgear characterized by comprising: a second external connection unit having a branch circuit connected to a circuit breaker by a conductor.
- (2) The gas insulated switchgear according to claim 1, wherein a part of the branch circuit is constituted by a disconnector.
