摘　　要：针对目前煤矿井下低压电网在漏电后备保护和选择性漏电保护方面的运行现状,从人身安全、供电可靠性等方面考虑,通过应用山东科技大学专利理论"零序基波时序鉴别"和低压漏电故障监测理论,设计了一种DJLXJ-1矿用隔爆兼本质安全型时序鉴别集中选漏保护装置方案。试验和运行结果表明,该保护装置能及时、准确地断开漏电回路,能够满足煤矿井下电网的漏电保护要求。In view of the current operation status of the underground low-voltage power grid in coal mine in terms of leakage back-up protection and selective leakage protection, considering personal safety and power supply reliability, a DJLXJ-1 mine flameproof and intrinsic safety time sequence identification centralized leakage protection device is designed by applying the patent theory of Shandong university of science and technology "zero sequence basic wave time sequence identification" and lowvoltage leakage fault monitoring theory scheme. The test and operation results show that the protection device can disconnect the leakage circuit timely and accurately, and can meet the requirements of the leakage protection of the underground power grid.
