PURPOSE:To prevent electric shock accident and to perform various works safely by providing a pair of supporting members, adjacent to a metering transformer, with connecting members and removing the connecting members when a bus is extended, inspected or repaired. CONSTITUTION:Connecting members 11 are provided between a pair of supporting sections 2, 4 disposed in adjacent to a metering transformer 8 located at a predetermined position in bus systems A, B. The connecting member 11 can be removed when power supply to one bus is interrupted while keeping power supply to the other bus. Consequently, when the bus 1 facility is extended, the bus facility 1 can be connected with the buses 1 at the adjacent supporting sections 2, 4 by removing the connecting members while keeping power supply to the bus system 1 including the metering transformer 8. Consequently, electric shock accident can be prevented and extension work can be carried out without totally interrupting power supply to the bus 1 facility. |
