摘　　要：为分析影响低压成型绕组电机定子绝缘介质损耗因数的工艺因素,研究了铁心不齐、油渍污染、绝缘受潮和绝缘漆流失4种因素对电机定子绝缘介质损耗因数的影响规律和相应的处置措施。结果表明:铁心不齐、油渍污染以及绝缘漆流失会造成电机绝缘介质损耗因数增量的增大,绝缘受潮后电机的介质损耗因数显著增大;其中绝缘漆流失造成介质损耗因数的增大可以通过二次浸漆使其减小。In order to analyze the technological factors affecting the dielectric loss factor of low-voltage forming winding motor stator,the influence rules of four factors including uneven core,oil contamination,insulation moisture,and insulation paint loss on the dielectric loss factor of stator and the corresponding disposal measures were studied.The results show that uneven core,oil contamination,and insulation paint loss lead to the increase of dielectric loss factor of the stator insulation,and the dielectric loss factor of the motor insulation increases significantly when the insulation gets damp.The rise of dielectric loss factor caused by insulation paint loss can be decreased by secondary impregnation.
