| Abstract: | The article introduces the method to really settle the high and low-pressure power supply wire net electric leakage current in coal mine well, emphasizing specially the influence factor of the distributed electric capacity of the long pull power supply electric cable to make sure electric leakage electric current, putting forward the intellectualized technique way of compensating the distributed electric capacity electric current in time. The paper expatiates the technical merit and shortcoming of the leakage electric current protection in domestic and international at the same time, analyzes that technical development trend. |
