ABB同步电机降压起动投全压动作异常分析及处理

Analysis and Treatment of Abnormal Action of ABB Synchronous Motor Starting with Reduced Voltage then Put into Full Voltage

某同步电机的启动方式为异步自耦变降压启动。针对一起电机非正常启动故障,结合现场情况分析了该同步电机启动动作异常的原因,并给出具体处理措施,排除了该电机启动故障,保证生产正常运行。

The starting mode of a synchronous motor is asynchronous autotransformer step-down starting.Aiming at an abnormal starting fault of the motor and combined with the field situation,this paper analyzes the cause of the abnormal starting action of the synchronous motor,and gives the specific treatment measures,so as to eliminate the starting fault of the motor and ensure normal operation of production.
