弱电测量信号干扰案例与分析

Cases and Analysis of Signal Interference in Weak Current Measurement

核电站堆外核测系统是一个弱电测量系统,其脉冲信号极易受到干扰,影响系统的稳定运行,对系统可用性造成影响。为此,介绍了田湾核电站堆外核测系统常见信号干扰情况,对干扰现象进行分析,提出了抗干扰解决方案。

The ex-core nuclear instrumentation system of nuclear power plants is a weak current measurement system,whose pulse signal is easily interfered,resulting in negative impact on stable operation and availability of the system.This paper describes the common signal interference of the ex-core nuclear instrumentation system of Tianwan Nuclear Power Plant,analyzes the interference phenomenon,and puts forward some anti-interference solutions.
