The direct current system feeder line air switch of the transformer substation is an air automatic switch with single function, and mainly has the functions of switching on and switching off branch loads, and timely switching off and isolating fault electricity when the feeder line has overcurrent or short circuit so as to avoid override tripping and total station direct current load voltage loss. However, the dc feeder line is not allowed to be disconnected once the dc feeder line is closed, because once the power supply is disconnected, the protection of the primary equipment is lost, and even an accident or an expansion of the accident is caused. Therefore, the branch power supply is not allowed to be disconnected at any time except when the equipment is subjected to power failure maintenance once. The grounding of a certain feeder line branch may occur during operation, and the direct current grounding may cause a serious consequence of protection misoperation or refusal, so we must search the grounding point as soon as possible and eliminate the direct current grounding fault, but the fact is that the direct current grounding fault searching and processing time is long in most cases, so that the direct current system has a long operation time with a fault, and potential safety hazards exist.
