摘要

Problem to be solved: to provide an arc detecting apparatus capable of accurately detecting an arc failure occurring in a transmission path.DC power supply 31 for generating DC power andAn arc detector 10 for detecting an arc fault occurring in a transmission path L1 connecting a power converter 50 that converts DC power to AC power isA first determination section 11 for judging whether or not there is a possibility of occurrence of an arc fault according to the current flowing through the transmission line L1 andIf there is a possibility of an arc fault,A stop 12 temporarily stops the current flowing through the transmission lineA second determination section 13 determines whether or not an arc fault has occurred in accordance with the input voltage of the power converter 50 supplied from the DC power supply 31 after the temporary stop of the current flowing through the transmission line L1 is released;.Diagram
