Claims

[Scope of utility model registration request]

The first to third power receiving cable heads or bushings connected to the ABC three-phase lines, respectively, and the first to third
equipment constituting first to third power receiving switching circuits that connect the busbars and the first to third cable heads or bushings to the first to third busbars, respectively.
a first power receiving unit branched from the busbar;
A transformer unit comprising branch conductors and equipment constituting the first to third transformer connection switching circuits for connecting the branch conductors to the transformer is connected to a common unit filled with insulating gas. In the gas-insulated switchgear housed in the container, the devices constituting the first to third power receiving switching circuits and the devices constituting the first to third transformer connection switching circuits are parallel to each other. The first to third busbars are arranged substantially along the first to third planes, and the first to third power receiving opening/closing lines are arranged at right angles to the first to third planes. The first to third branch conductors are connected to a circuit, and each of the first to third branch conductors is disposed along the first to third plane, and each of the at least two branch conductors is internal to the first to third branch conductor. A gas-insulated switchgear, characterized in that the power receiving circuit is connected to a bus bar connected to a switching circuit, and the power receiving circuit is arranged along a plane different from the plane in which the power receiving circuit is arranged.
