摘　　要：主要针对△接电机在进行Y-△自动时电机无法启动的现象进行分析,重点对电机接线错误引起的无法启动进行剖析。通过出厂测时的△-Y-△模拟运行电路测试,可有效检测出存在这种隐蔽故障电机的错线故障,从而改正接线,恢复电机Y-△启动线路的正常运行。This paper mainly analyxes the phenomenon that the delta-connected motor canmot be started during Y-△starting,focus on the failure to start caused by the wiring error of motor.?Through testing the △-Y-△simulation operation ciruit at factory test,the fault of the wiring eror of the motor with the hidden fault can be electively detected,thus the wiring enor can be omected and the normal opernation of Y-△starting circuit of the motor is restred.
