Circuit breaker tanks(10a,10b,10c), and disconnector-bus tanks(20a,20b,20c) filled with an insulating gas are vertically coupled and arranged to be partitioned by an insulator. Cable connection units(30a,30b,30c) are installed on lower parts of the circuit breaker tanks and connected to power cables(31a,31b,31c). The circuit breaker tanks receive circuit breakers(40a,40b,40c) which are coupled to upper parts of the cable connection units and artificially block load current in generation of abnormal current or voltage. The disconnector-bus tanks receive disconnectors(50a,50b,50c) and buses(60a,60b,60c). The disconnectors are electrically connected to upper parts of the circuit breakers. The buses are electrically connected to upper parts of the disconnectors. A panel(70) is installed on one sides of the circuit breaker tank and the disconnector-bus tank and receives a circuit breaker controller(71) and a disconnector controller(73).
