According to the Coal Mine Safety Regulations requirements leakage current shall not exceed 30mA ? s, so for the underground leakage protection requirements with enough reliability and the corresponding sensitivity to maintain the safety and stability of power supply system of coal mine. With the development trend of the digital mine, leakage protection device also by the traditional simulator towards the development of integrated system by microcomputer monitoring and processing of information leakage of protection. This paper briefly introduces the current leakage protection technology at present With the development of the coal mine. Only to leakage protection for the coal mine production safety escort.
