摘　　要：分析了目前国内普遍应用的本质安全型矿灯技术水平以及存在的问题,虽然矿灯锂电池电源输出都具备三级保护电路(ia),但是在锂电池电源内部电极直接短路的罕见故障发生时,任何外部保护都是无能为力的,而且破坏力极大。介绍了在锂电池电源内部发生电极直接短路故障时,一种能够抵御其出现热失控严重后果的电源盒的设计与制造。Analyzes and discusses the technical level and existing issues and problems of intrinsically safe miner′ s lamps currently widely used in China. Even though the output of lithium battery power supply of miner′s lamp has three-level protection circuit(ia), any external protection is useless when the rare fault of direct short circuit of internal electrodes in lithium battery happens. This is destructive.Introduces the design and manufacture of a power box which is capable of resisting the severe consequence of thermal runaway, when fault of direct short circuit of internal electrodes in lithium battery occurs.
