Abstract
A gas-insulated switchgear apparatus is disclosed, in which a bus bar-dividing unit is interposed through main bus bars between feeder units connected to a transmission line or a transformer. The main bus bars are arranged in substantially the same axis. A circuit breaker of vertical type making up the bus bar-dividing unit includes an upper electric path and a lower electric path. The lower electric path is connected to one of the main bus bars while the upper electric path is connected to the other main bus bar at a position displaced axially of the main bus bar opposed to the circuit breaker of vertical type. This construction with the circuit breakers of vertical type arranged on the same axis facilitates maintenance and inspection.
