浅谈三大保护在资源整合矿井低压供电系统的应用

Application of the three major protection in low voltage power supply system of resource integration mine

供电系统在矿井安全生产中占有非常重要的地位,合理利用三大保护是保证矿井低压供电系统安全运行的屏障。保障供电系统安全运行,保证电能质量,防止故障扩大和事故发生,是三大保护重要性在矿井低压供电系统中的重要体现。

The power supply system occupies a very important position in the mine safety production; the reasonable utilization of three major protection is a barrier to ensure the safe operation of the mine low voltage power supply system. To guarantee safe operation of power supply system, ensure the quality of electric energy, and prevent the occurrence of expansion of the fault and accident, is an important manifestation of the importance of three major protection in low voltage power supply system in the mine.
