徴とするバイパス工法用電源切替装置。 Connection between a low-voltage distribution line that is connected to a high-voltage distribution line in a healthy section via a transformer and a low-voltage distribution line that is connected to a high-voltage distribution line in a section scheduled for construction via another transformer. In the power supply switching device for the bypass construction method, the power supply switching device has a power supply side connection terminal for connecting to the low voltage distribution line in the healthy section, and a load side connection terminal for connecting to the low voltage distribution line in the planned construction section. A non-contact switch is interposed between the connecting terminals, and the non-contact switch is connected instantaneously upon receiving a command signal, and a relay contact is connected in parallel to the non-contact switch. Furthermore, a detection circuit is connected to the load-side connection terminal, which applies a conduction command signal to the non-contact switch and relay contact, respectively, when it detects that the load-side connection terminal becomes non-voltage. Features: Power switching device for bypass construction method.
