ILX56-MM

匝间短路和局部放电是目前变频电机绝缘类型故障中较为常见的形式，其中匝间短路一般表现为电机当中的某一个线圈出现大面积的损坏，局部放电则集中表现在电机线圈外观较好，但是绝缘电阻已经呈现为零的状态。此时，电机绝缘系统受到的损坏影响，并不只是某一单一因素的影响，而是局部放电、局部介质发热等因素造成的。

　　局部放电：目前在中小容量变频器运行过程中，普遍都是选择利用 IGBT功率器件脉宽调制技术，该元件相互构成的 PWM调速装置可以提供高耸的尖峰，波峰具有陡峭的前沿特征，同时其调制频率较高，所以对绝缘带来的危害影响较为严重。

　　局部介质发热：如果在电机当中的电场强度 E已经明显的超过绝缘临界值时，那么其介质的损耗程度也会越来越严重。尤其是在频率不断上升的形势下，局部放电也会有所增加，进而产生热量，这些热量势必会带来更加严重的漏电流等问题 ［1］。久而久之，不仅会导致单位体积的损耗有所增加，而且电机的温升也会不断上升，无形中导致绝缘老化速度越来越快。

　　循环交变应力：通过 PWM变频电源供电方式，变频电机在投入正式使用时，可以直接通过变频器提供的各种方式进行制动，电机绝缘在循环变应力的影响下，其整个绝缘老化速度会越来越快。由于在前期设计环节并没有综合考量电气以及机械整体性等，所以电机的老化进程速度会不断提升。
