摘要
随着变频器的广泛应用,使其成为工厂自动化领域最大的电磁污染源,对自动化测控系统产生较大的干扰,会导致系统监测失准、控制失灵,严重的会导致系统出现停车或安全事故。介绍变频器干扰的来源、传播方式以及在实际应用中遇到不同情况的干扰问题时的处理方法。
Frequency converter widely used in plant automation field becomes the biggest electromagnetic pollution source,which may bring larger interference to automatic control system,cause the misalignment and control failure in system monitoring,and even lead to plant shutdown or safety accident.This paper is to talk specifically about the source of the inverter interference,its spread pattern,and some practical application in case of interference.
