ABSTRACT:
Gas-insulated switchgear equipment includes a plurality of vertical-type circuit breakers electrically connected in series, and outside led-out devices connected to connected portions of a series connection of the circuit breakers and at least one main bus bar connected to two of the plurality of circuit breakers located at both ends of the series connection. In the equipment, the circuit breakers are a vertical type circuit breaker and are arranged on a substantial straight line and led-out portions for leading out terminals formed in the circuit breakers in a direction perpendicular to a direction of the arrangement of the circuit breakers, and connecting bus bars interconnecting the circuit breakers in series and the outside led-out devices are disposed on one side of the circuit breakers and the at least one main bus bar is disposed on the other side of the circuit breakers. Therefore, the fixing area can be reduced and the connection between the at least one main bus bar and the circuit breakers and between the circuit breakers and the outside led-out devices can be easily established.
