Abstract

PROBLEM TO BE SOLVED: To reduce cost with a connection part arranged rationally, reduce its installation space, and minimize the length of a bus by a method wherein, in the connection part of a device body to a plurality of external devices, an in-phase device which constitutes the connection part and the bus are arranged on the same vertical plane. SOLUTION: In a connection part, in one phase, in which a device body is connected to an external device, a cable connection part (a cable head) 1a, cable heads 1b, 1c whose performance is equal to that of the cable head, a disconnector 3, a current transformer 4 and a circuit breaker 5 are arranged on the same straight line. Regarding two other phases, a cable head and a device are arranged similarly on the same straight line. By such an arrangement, a size in a direction perpendicular to an axis, which connects the circuit breaker 5 to the cable head 1a is shortened, and a gas-insulated bus (a bus) in an ordinary device is not required. In addition, since the installation space of the device body is reduced, the length of a bus is made minimum in total, so that the cost of the device body can be reduced.
