Claims

[Scope of utility model registration request]

Consists of multiple power transmission line lines into which power transmission lines are drawn for transmitting and receiving power, two main bus line lines to which these power line lines are connected, and a bus line communication line that connects these main bus line lines. A gas-insulated switchgear with a double busbar interconnection system, in which two busbar interconnection shield disconnectors are used as the equipment constituting the busbar interconnection line, and each busbar interconnection disconnector is connected in series. The busbar configuration consists of two earthing switches and one
In the case where the two busbar communication disconnectors constituting the busbar communication circuit are installed on one side of each of the main busbar circuits that are arranged close to each other in parallel, A gas insulated switchgear characterized in that a communication busbar which is arranged in a straight line in a perpendicular direction and connects each of the busbar communication switches and disconnectors is arranged in a direction perpendicular to the main bus line.
