Abstract: Study was carried out on the design of overcurrent protection of the relay protection device of the underground power
supply system. Based on the design of the overcurrent protection circuit of the relay protection device, this paper carried out a
comprehensive summary of the design of the overcurrent protection program and the debugging of the overcurrent protection device,
hoping to provide help for better application of the relay protection device in mine production.

Key words: mine; power supply system; relay protection device; overcurrent protection; circuit design
