Claims

[Scope of utility model registration request]

In a gas-insulated switchgear with a phase-separated double-bus system, in which devices such as circuit breakers are connected to two sets of gas-insulated main buses for each phase via two sets of bus-switching disconnectors that are also phase-separated. , the disconnection parts of the two sets of busbar switching and disconnecting switches are housed in a metal container that is one pressure vessel, and the negative electrodes of the movable side and fixed side electrodes of the two sets of busbar switching and disconnecting switches are arranged in the middle. A gas insulated switchgear characterized in that the other electrode is arranged on both sides, and the electrode arranged in the middle is shared by two sets of disconnectors.
