摘要
结合煤矿电气保护的现状,对煤矿电气保护中漏电保护、过电流保护、断路保护的选择性进行分析,选择性电器保护是实现保护智能化、高效化、安全化的前提,可使整个电气系统在发生故障时能够自动隔离故障。
Combined with the present situation of coal mine electr ical protection, selectivity of coal mine electric protection are analyzed, so as to ensure the normal operation of the power supply safety and equipment in mine, but also to protect the entire electrical system of automatic fault isolation when fault occurs, the fault range control, reduce the fundamental measure of fault hazards.
