交流电机绕组短路故障检查

Short-circuit Failure of AC Motor Windings

绕组短路后,定子的磁场分布不均匀,三相电流不平衡,会使电机运行时的振动和噪声加剧,严重时电机不能起动。而在短路的线圈中会有很大的短路电流,导致线圈迅速发热和烧毁。

Short-circuit failure of motor windings will result in uneven distribution of the magnetic field, unbalanced current of three-phase, great noise vibration during operation and even failing to start up of the motors. There will be large short-circuit current in the short-circuit winding, causing the windings being heated, smoked and burned out.
