摘　　要：主要讲述三相异步电动机定子绕组局部烧坏的原因和表现形式,对绕组局部绝缘老化损伤造成的接地匝间;轴承故障、机械卡阻、过载运行造成的绕组内部线圈烧毁现象进行分析。说明绕组绝缘防护的重要性和设备运行检测需要注意的事项。This paper mainly describes the causes and manifestations of local burning fault of three-phase induction motor stator windings,and analyzes the grounding interturn of windings caused by the aging damage of local insulation and the burning out phenomenon of inner coils caused by the bearing fault,mechanical jamming and overload operation.This paper explains the importance of insulation protection of windings and the matters that should be paid attention for the equipment during operation and inspection.
