煤矿电缆短路故障限流控制技术研究

Study on Current-Limit Control of Short-circuit Fault in Mine Cable

煤矿电缆短路故障是威胁煤矿安全生产的重大电气隐患,其应对策略应着力于从控制其短路故障时的大电流入手,本文从分析电缆短路故障对井工煤矿的危害入手,总结了我国煤矿限流控制技术的发展成果,重点研究了典型故障限流器FCL的作用机理,并对其在煤矿电缆短路故障中的实效性进行了研究。

By analysis of the hazards of cable short-circuit fault to safety production in coal mines,the paper studies on the mechanism of typical fault current limiter,which can control the short circuit faults effectively.
