PLC高压电机控制常见故障的处理

Treatment of Common Faults in PLC High Voltage Motor Control

在轧钢产线因PLC高压电机的启停以及保护控制发生故障,造成保护动作不安全,PLC的保护得不到有效执行,造成不必要的设备和生产事故。文章分析了高压电动机PLC控制常见故障及解决措施。

In the steel rolling line,because the control of high voltage switch cabinet of high voltage motor start and stop and protection application can cause some problems,resulting in protection action is not safe.The protection of PLC cannot be effectively implemented,resulting in unnecessary equipment and production accidents.This paper analyzes the common faults and solutions of PLC control of high voltage motors.
