Claims

[Claims for Utility Model Registration] First and second transformers, an electric power supply and demand instrument transformer, a power receiving side switching circuit provided between a line and the electric power supply and demand instrument transformer, 1 of the electric power supply and demand instrument transformer and the first and second transformers;
Two sets of power receiving units each having a transformer primary side switching circuit provided between the two sets of power receiving units are installed in parallel, and the transformer primary switching circuits of the two sets of power receiving units are connected via a bus bar. In the regular standby two-circuit gas-insulated power receiving equipment, the transformer primary side switching circuit includes a bus-side disconnect switch provided between the power supply and demand instrument transformer and the bus, and a bus-side disconnect switch installed between the bus and the first and second circuits. The transformer is equipped with at least first and second transformer primary side disconnectors that respectively open and close between the primary side of the transformer, and the busbar side disconnector is housed in an independent busbar side element container and is gas insulated. A first transformer connecting cable connector and a busbar cable connector are attached to the side wall of the busbar side element container, and a second transformer connecting cable connector is attached to the upper part of the busbar side element container. is installed, and the first and second transformer primary side disconnectors are housed in first and second cases supported by the tanks of the first and second transformers, respectively, and are gas insulated. and the cable connectors attached to the first and second cases and the first and second transformer connecting cable connectors are connected by a cable to connect the first and second transformers. A regular standby two-circuit gas-insulated power receiving facility characterized in that a primary side disconnector and the bus bar are electrically connected.
