PROBLEM TO BE SOLVED: To provide a DC power supply reclosing detector which detects a reclosing of a DC power supply. SOLUTION: A DC power supply reclosing detector has a logic device 31 and a recorder and indicator. The logic device 31 has a reset input terminal R to which a system clear signal generated at the time of rise of supply voltage is input, a set input terminals to which a flag set signal generated after the rise of supply voltage is input, and an output terminal Q which outputs a signal which is in a reset state or in a reverse set state based on the input of the system clear signal or flag set signal. The recorder and indicator records or indicates the data about the reversal of the logic device 31 from a set state to a reset state. |
