煤矿供电故障预警系统的设计及选型实现

Design and Selection of Early Warning System for Coal Mine Power Supply Faults

煤矿的自动化开采对于供电系统的安全稳定运行提出了较高的要求,由于供电系统自身的复杂性及井下作业的恶劣条件,使得采用人工检修的方式无法满足自动化开采的需求。设计一种煤矿供电故障预警系统,依据供电系统的故障类型,对供电设备进行运行参数的监测及处理,及时的发出预警信号,避免造成供电系统的故障,保障煤矿供电系统的安全稳定运行,并对系统的选型实现进行了论述。

The automatic mining of coal mines puts forward higher requirements for the safe and stable operation of the power supply system.Due to the complexity of the power supply system itself and the harsh conditions of underground operations,manual maintenance cannot meet the requirements of automatic mining.Therefore,an early warning system for coal mine power supply faults is designed.According to the fault types of the power supply system,the operating parameters of the power supply equipment are monitored and processed,and early warning signals are sent out in time,so as to avoid causing faults in the power supply system and ensure the safe and stable operation of the coal mine power supply system,and the selection and implementation of the system are discussed.
