えて閉路状態とし逆送を行うものである。 Generally, two or more ground-mounted transformer devices of this type are installed. The low-voltage side of the ground-mounted transformer device is connected to the low-voltage side of an adjacent ground-mounted transformer device by a connecting line 9. In normal operating conditions, this ferry uses a short circuit plate 13 to open the circuit, but if an adjacent transformer device fails, the short circuit plate 13 is switched to close the circuit and perform reverse transport.

での危険性があつた。``Problem to be solved by the invention'' When transferring power back to an adjacent transformer device, open the high voltage switch 11 of the transformer device to be sent back, temporarily put the transformer device in a rest state, and then connect the low voltage side shorting plate 13. It was necessary to switch to line 9 and reverse feed. Furthermore, in order to avoid shutting down the transformer device, it is necessary to switch the low-voltage side shorting plate 13 while the line is live, which poses a safety risk.

になつている。"Function" With the above configuration, the low voltage current limiting fuse 7 attached to the main branch conductor 8 can be replaced without any problem, and the contact line switch 4 can be opened and closed using a dedicated auxiliary handle. . That is, the dedicated auxiliary handle is designed to pass between the main branch conductors with the low voltage door of the low voltage branch panel open and to operate the opening/closing part of the contact line switch located at the rear up and down.

It is connected to the connection line switch 4 through the connection line conductor 5, and is led out by the connection line conductor 5. On the other hand, the main line 9 has a structure in which it is led out from the conductor 3 via a low voltage current limiting fuse 7 and a main line branch conductor 8.
