A ring-shaped power supply system comprises: a plurality of relays (RL) provided at intervals from each other along a ring-shaped power source wire (ML); a plurality of detection units (5), each provided between ones of the relays (RL), for detecting an electrical change caused by a disconnect occurring in the ring-shaped power source wire (ML) when such a disconnect has occurred; and an arithmetic processing unit that identifies a location of the disconnect in the ring-shaped power source wire (ML) on the basis of the electrical change detected by the plurality of detection units (5) and cuts off the relays (RL) located on both sides of the location of the disconnect.
环形供电系统包括多个继电器(RL)、多个检测部(5)、以及运算处理部,多个继电器(RL)相互分离地设置在环形电源线(ML)上,多个检测部(5)分别设置在各继电器(RL)之间,并且用于在环形电源线(ML)发生断线时检测由断线引起的电气变化,运算处理部根据由多个检测部(5)检测出的电气变化,确定环形电源线(ML)的断线部位,使位于该断线部位两侧的继电器(RL)断开。
