摘要:

介绍了江都三站电机定子绕组匝间短路的故障过程,分析了故障发生的原因。提出采用“丢线圈法”应急处理方法,实现了电机短期内的应急运行。并采用ANSOFT有限元软件分析了丢线圈后电机内部磁场的变化。实践证明:该方法在线圈损坏不多、轻负载运行的情况下,作为应急处理是可行的。

This paper introduces the treatment of interturn short circuit of the main motor in Jiangdu third station and analyzes the cause of the malfunction. Fault analysis and treatment of interturn short circuit of the main motor in Jiangdu third station is introduced in this paper. The method of the “lost coil method” is proposed to realize the motor run during the short term. The motor’s inner magnetic field is analyzed using ANSOFT. The results show that the “lost coil method” as an emer-gency treatment is feasible when coil is not damaged too much and the motor is under the case of light load operation.
