矿井直流架线电机车杂散电流的危害与防治

Hazard and prevention of stray current in electric locomotive with mine direct current

针对杂散电流对井下安全生产带来的危害,分析了矿井架空牵引网络产生杂散电流的原因,对杂散电流可能造成的严重危害作了说明,采用回流与不回流钢轨人为绝缘、增大回流钢轨的截面积等方法来治理杂散电流,减少其带来的各种危害,从而保证矿井的安全高效运行。

Based on harms of stray current to underground safety production, its reasons produced by overhead mine traction network was analyzed. At the same time, the possible serious harm was described in detail. Therefore, reflux and non-reflux steel rail were used to insulate and the cross-sectional area of backflow rail was applied to eontrol stray current, which reduced harms it brought and ensured safe and efficient operation of the mine.
