摘　　要：设计和研究了煤矿低压馈电开关智能保护系统,能提升低压供电系统的可靠度。首先研究了矿井低压馈电开关保护和判别机理、短路现象、负序电流保护和漏电保护机理。并设计了系统硬件,完成整体和逻辑结构设计,给出采样、信号处理,报警、驱动模块。进而完成系统软件设计,实现主控流程、模数转换、显示和漏电监测的设计。Designs and studies the intelligent protection system of coal mine low voltage feed switch,which can improve the reliability of low voltage power supply system. Firstly, the protection and discrimination mechanism, short circuit, negative sequence current protection and leakage protection mechanism of mine low voltage feed switch were studied. And the design of the system hardware to complete the overall and logical structure design, given sampling, signal processing, alarm, driver module. And then complete the system software design, to achieve the master control process, digital-analog conversion, display and leakage monitoring design.
