Leakage protection is one of the three major protections in coal mines and is a crucial safeguard for the safety of underground workers. Based on an analysis of the current state of selective leakage protection systems in coal mine load centers, this paper designs a leakage fault protection system for coal mine load centers using a combination of an additional DC power supply method and zero-crossing triggering method, thereby improving the reliability of leakage protection in coal mine load centers.
