Abstract: In a one-and-a-half circuit breaker system gas-insulated switchgear assembly for three-phase AC transmission, the circuit breakers are located on a common horizontal floor directed in Y direction. First main bus bars extending in X direction are located above the first circuit breakers. The positions of the first main bus bars in different phases are different from one another only in height. Similarly, the second main bus bars extending in X direction are located above the third circuit breakers. Each phase of the main bus bars and disconnecting switches is located in a common horizontal plane. The heights are different for different phases. Relative locations of the disconnecting switches are substantially common for every phase horizontally, but are shifted in the X direction.
