摘要
结合目前井下低压电网过流保护的现状,探讨了井下过流保护出现误动与拒动的诸多原因,以便给采用新原理的过流保护的研究者和改进现有过流保护的使用者提供一些具体的论据。
Combined with present situation on overcurrent protection of low voltage electrified wire netting in mine,analysed several reasons on appeared mis-start or refuse-start of overcurrent protection in mine,thus provided some concrete arguments for research workers and users of overcurrent protection.
