<P>PROBLEM TO BE SOLVED: To provide a DC distributing system which can inform a user of abnormality of a DC distributing electric circuit. <P>SOLUTION: The DC distributing system is equipped with a plurality of DC apparatuses 3, which has a functional section 30 that is branched and connected to a DC distributing electric circuit 2 and is supplied with DC power by the DC distributing electric circuit 2, and a branch breaker 1, which has a transmitter 15 that transmits an inspection signal via the DC distributing electric circuit 2 to each of the plurality of DC apparatuses 3, a current detector 16 that detects a currents flowing in the DC distributing electric circuit 2, and an abnormality detector 17 that judges whether abnormality is occurring in the DC distributing electric circuit 2 or not. The DC apparatus 3 is equipped with a receiver 31, which receives an inspection signal, a controller 33, which takes an inspecting action for stopping the feed from the DC distributing electric circuit 2 to the functional section 30 when it receives the inspection signal, and an informing device 34, which performs information at occurrence of abnormality. The abnormality judger 17 judges it to be abnormal if a current value detected by the current detector 16 is over a threshold for abnormality judgement, when inspecting actions are performed in all of the plurality of DC apparatuses 3. <P>COPYRIGHT: (C)2009,JPO&INPIT |
