Abstract
In a gas insulated switchgear equipment device, at least one gas insulated main bus bar is arranged on an attachment surface and a plurality of feeder units each having one end connected to the gas insulated main bus bar and the other end connected to an insulating terminal are arranged along a longitudinal direction of the gas insulated main bus bar, thereby constituting a substation equipment device. A gas insulated bus-section-unit is arranged on a portion of the gas insulated main bus bar and has at least a circuit breaker and disconnecting switches connected to both ends of the circuit breaker, and one end of the bus-section-unit is connected to the corresponding gas insulated main bus bar and the other end of the bus-section-unit is provided with at least one external lead-out device connectable to an external connecting device. With this arrangement, by the use of the bus-section-unit arranged on the portion of the gas insulated main bus bar, the substation equipment separated or increased can be easily interconnected or renewed.
