摘　　要：分析了矿用低压漏电保护装置的现状,针对已存在的漏电电阻检测问题,如"漏电电阻检测原理"、"零序电压法",提出了改正措施,其中ZBL-L型矿用隔爆型低压漏电保护装置很好地解决矿用低压漏电问题。该装置通过实际运行表明,能达到准确动作、安全可靠。Analyzes the current situation of mining low voltage leakage protection devices. On account of the leakage resistance testing problem, such as ＇leakage resistance testing principle＇, ＇zero sequence voltage method＇ , proposes the improved verification measures. It concludes that the ZBL-L mining flame-proof low voltage leakage protection devices well solves the low voltage leakage problems. This device can act correctly, safe and reliable by practical operation.
