摘要
针对田湾核电站主泵电机定子铁芯和线圈温度在电机启动时的电磁干扰问题,通过对电磁干扰三要素的分析,验证比较了几个解决措施,实践证明利用温度变送器优良的电磁兼容性能,在测量回路中增加温度变送器,能够较好地解决电机启动时强交变磁场对温度测量的影响。本文分析、解决电磁干扰问题的思路和方法,对同行电站的类似应用具有一定的参考意义。
About the electromagnetic interference problem in the measurement of the motor stator core and winding temperature of reactor coolant pump when motor starts,based on the analysis of EMI three factors,we compared several solutions,it was proved that the interference of the alternating magnetic field to the temperature measurement was solved by adding temperature transducers in the measurement circuits,which take advantage of the excellent electromagnetic compatibilityperformance of temperature transducers.The approach to analyze and solve electromagnetic interference problem in this paper has definite reference value on similar application for peer stations.
