摘　　要：针对目前煤矿高压电网多级供电方式的缺点,提出了一种高可靠简约型井下6 kV供电结构,优化后的电网结构为3级干线式供电,解决了多级纵向干线过流、漏电保护设置困难的技术难题,彻底消除煤矿高压电网长期存在的越级跳闸问题。For the disadvantages of coal mine high voltage grid multi - level power supply way, the paper proposed a reliable simple power supply structure for mine 6 kV power structure. The optimized grid structure is three level main type power supply. This method can solve technical problems of multi -level longitudinal grid over- cmTent and leakage protection setting difficult, eliminate the long - standing problems of override trip for coal mine high - voltage power grid
