摘要
建立了矿井电器三相交流电对测控信号线的电容性干扰模型,用复数运算法计算了稳态情况下的干扰电压,分析了布线位置对干扰的影响,并将结果推广到尖峰脉冲群下的供电线路。
A capacitance interference model of three pulse alternating current power supply on signal wire is established.Using complex number algorithm,the interference voltage in stable state is calculated and the influence on the voltage due to the arrangement of the wire is analyzed.At last this result is extended to the power supply incorporated with peak pulse group.The conclusion about the relation between the arrangement of the signal wire and the interference voltage has provided a base for the design of microcomputer for monitoring and control.
