摘要
针对目前矿井低压电网漏电保护系统存在的不足,设计了基于直流电流传感器检测和单片机控制的新型直流检测式选择性漏电保护系统。模拟试验表明,该系统各项性能指标均达到了设计要求,效果良好。
Base on the shortage existed in the electric leakage protection system of the present mine low voltage electric power network, a new DC measurement type selective electric leakage protective system with DC sensor inspection and micro processor control was designed. After the simulation test, the results showed that each performance index of the system could reach the design requirements with good results.
