Claims (1)

[Scope of Claim for Utility Model Registration] (1) A first power receiving unit configured by gas-insulating the components of the switching circuit for receiving power from the regular line, and the components of the switching circuit for receiving power from the protection line. a second power receiving unit configured with gas insulation; a power supply and demand instrument transformer connected to the first and second power receiving units; and a power supply and demand instrument transformer connected to the first and second power receiving units; first and second transformers 1 respectively disposed between the transformer bank;
In the regular standby two-line power receiving equipment equipped with a secondary side disconnector, the first and second transformer primary side disconnectors are disposed within the first and second power receiving units, respectively. A second power receiving unit is arranged with an interval left and right, and the first and second power receiving units are configured symmetrically so that the power supply and demand instrument transformer is connected to the power supply and demand instrument transformer from opposite side walls of the containers of both units. Five bushing terminals with terminals to be connected are led out into the air, and the power supply and demand instrument transformer is disposed between the first and second power receiving units and connected to the first and second power receiving units. A regular standby two-line power receiving facility characterized in that it is connected via an air conductor to five bushing terminals each led out from a power receiving unit. (2) A first power receiving unit configured with gas-insulated switching circuit components for receiving power from the regular line, and a second power receiving unit configured with gas-insulated switching circuit components for receiving power from the protection line. a power receiving unit, a power supply and demand instrument transformer connected to the first and second power receiving units, the power supply and demand instrument transformer, first and second transformer banks;
between the first and second transformer primary side disconnectors respectively arranged between the power supply and demand instrument transformer and the primary side of the third transformer bank for expansion. In the regular standby two-line power receiving equipment, the first and second transformer primary side disconnectors are arranged on the first and second power receiving circuits, respectively. The first and second power receiving units are arranged within the unit and are spaced apart from each other in the left and right directions, and the first and second power receiving units are configured symmetrically so that they are separated from opposite side walls of the containers of both units. Five bushing terminals each having a terminal to be connected to the electric power supply and demand instrument transformer are led out into the air, and the third transformer primary side disconnector is an independent container filled with insulating gas. A transformer expansion disconnector unit is configured by being housed in the transformer, and the electric power supply and demand instrument transformer is disposed between the first and second power receiving units together with the transformer expansion disconnector unit. Regular standby two-line power receiving equipment, characterized in that the five bushing terminals respectively derived from the first and second power receiving units are connected to the transformer expansion disconnector unit via an air conductor. .
