浅谈煤矿35 kV变电站微机监测监控与保护回路

煤矿35 kV供电系统正常运行过程中,每小时都要记录电气设备运行状态、线路电压、电流、功率等参数。当供电系统发生故障时,系统中电流和电压参数会有变化。要求值班人员除了能及时迅速做出判断外,还必须正确选择合理的供电参数,加强对电气设备的维护。随着微机技术应用的迅速发展,采用微机适时监测监控,以确保电气设备的安全运行。对煤矿35 kV变电站微机监测监控与保护回路进行了探讨。

Discussion on Microcomputer Monitoring and Protection Circuit of 35 kV Substation inCoal Mine

During the normal operation of the 35 kV power supply system in the coal mine,the operating status,line voltage,current,power and other parameters of electrical equipment are recorded every hour.When the power supply system fails,the current and voltage parameters in the system will change.In addition to timely and rapid judgment,the duty personnel must also correctly select reasonable power supply parameters to strengthen the maintenance of electrical equipment.With the rapid development of the application of microcomputer technology,the microcomputers are used for timely monitoring to ensure the safe operation of electrical equipment.This paper discussed the microcomputer monitoring and protection circuit of the 35 kV substation in the coal mine.
