Claims

[Claim for Utility Model Registration] A power supply and demand meter consisting of a power receiving element consisting of components of a switching circuit connected to a line housed in a container filled with insulating gas, and an external terminal consisting of an air bushing. A transformer element equipped with a transformer, and a transformer primary element, which consists of components of the switching circuit connected to the primary side of the transformer, housed in a container filled with insulating gas, in this order. Gas-insulated switchgear, which is arranged side by side and connected via aerial wiring between the power receiving element and the transformer element and between the transformer element and the primary side element of the transformer, is connected to the service line and the backup line. The primary side disconnector element of the transformer of the gas insulated switchgear for the regular line and the primary side element of the transformer of the gas insulated switchgear for the standby line are interconnected via a gas pipeline. In the gas-insulated switchgear, the power receiving element of the gas-insulated switchgear for the regular line and the power-receiving element of the gas-insulated switchgear for the backup line are integrated into a unit to constitute a power receiving unit, and the gas-insulated switchgear for the regular line is transformed. The transformer element and the transformer element of the gas-insulated switchgear for the service line are combined into a unit to form a transformer unit, and the transformer primary side disconnector element of the gas-insulated switchgear for the service line and the gas-insulated switchgear for the backup line are combined into a unit. The transformer primary side element of the switchgear is connected to the transformer primary side element through the gas pipe line to form a unit, and the power receiving unit, the transformer unit, and the transformer 1 are connected to each other.
Gas insulated switchgear equipment characterized in that it is supported on separate unit bases that can be separated from the next unit, and that the units are configured to be separable.
