摘要
阐述了煤矿高、低压供电系统,并从高压线路、高压开关、继电器三个方面分析了系统所产生的问题,并提出相应的预防和改进措施。分析认为只有做好煤矿井下供电系统运行维护工作,及时解决所存在的问题,才能保证煤炭井下作业的安全性和可靠性。
Coal mine high and low voltage power supply system is expounded, and from three aspects of the high voltage lines, high voltage switch, the problems are introduced, and corresponding prevention and improvement measures are put forward.Only do a good job in the coal mine power supply system operation maintenance work, timely solve the problems, the safety and reliability of coal mine can be guaranteed.
