。By the way, in substations and the like, for example, the size of the building is reduced by installing transformers on the first floor and circuit breakers on the second floor. In this case, it is necessary to connect the output side of the transformer and the terminal 9 on the input side of the circuit breaker with a conductor. Therefore, when using a circuit breaker as shown in FIG. 2, a bushing is passed through the floor of the second floor and the circuits are connected to each other via a conductor passing through this bushing.

Note that parts given the same reference numerals as in FIG. 2 indicate the same or corresponding parts. According to the present invention, one branch pipe, that is, a branch pipe 3 having an input terminal 9 at its tip, is installed on the lower surface of the tank 1 and extends downward from the tank 1. A flange 12 may be provided on the branch pipe 3 so that it can be divided using this flange.
