Claims

[Claims for Utility Model Registration] Components of a line-to-bus switching circuit that connects a railway line and a busbar, a transformer primary-side disconnector provided between the busbar and a transformer connection part, and the disconnector. Two switchgear units are provided, each equipped with a transformer primary side grounding switch that grounds the terminal on the transformer connection side of the transformer, and the busbars of the two switchgear units are connected to each other. In the line power receiving gas insulated switchgear, the transformer primary side disconnector and the transformer primary side grounding switch are housed together with the components of the line busbar switching circuit in a cubicle-shaped container filled with SF ₆ gas. , the transformer connection part is arranged in a cylindrical container gas-separated from the cubicle-shaped container, and the cylindrical container has a nozzle stand for attaching a test voltage application bushing and a transformer connection bushing. A two-line power-receiving gas-insulated switchgear characterized by being provided with a mounting portion.
