In order to realize the ground management center of high and low voltage equipments in the normal operation,fast judgment and handling fault, developed a kind of coal mine underground power monitoring system. The system consists of underground flameproof power distribution switch and computer monitoring system formed. Inoue underground flameproof switch to TMS320F2812 digital signal processor (DSP) series as control core inoue> computer monitoring system can monitor underground power grid, display and alarm parameters over voltage, leakage,overload,short circuit fault,etc. At present the system has already been used to coal,actual effect is remarkable.%为了实现地面管理中心对井下高低压设备的正常操作、快速判断和处理故障,研制了一种煤矿井下电力监控系统.该系统由井下防爆配电开关和井上计算机监控系统构成.井下防爆开关以TMS320F2812系列DSP芯片为控制核心,井上计算机监控系统可实时监测井下电网参数、显示和报警过欠压、漏电、过载、短路等故障.目前该系统已应用到煤矿,实际运行效果显著.
