摘要

10 kV异步电动机在运行过程中

机械振动会对绕组端部主绝缘造成横向撕裂

产生相间放电

大大降低其绝缘性能。针对这一问题

笔者对高压电动机真机定子绕组端部进行分析

设计制作了绕组相间放电模型

研究了10 kV异步电动机真机定子绕组在不同电压等级下放电指纹的分布规律。在屏蔽室环境下对其施加电压诱发相间放电

提取表征放电特性的特征量

观察并记录相间放电热点分布。该研究为10 kV异步电动机主绝缘在线监测及故障诊断提供理论依据。

Abstract

During the operation of 10 kV asynchronous motor

bar-to-bar discharge will be generated because of transverse tear of end-winding

which can generally reduce the insulating properties. In order to solve this problem

a real bar-to-bar discharge model is designed by abrading the junction region between the low resistance layer and the high resistance layer of a real stator winding. The experiment is performed in the electromagnetic shielding room and the distribution patterns of bar-to-bar discharge under different voltages are analyzed. Hot pot distribution in the discharge region is observed and recorded through infrared camera. The research will provide a judging basis for the on-line monitoring and fault diagnosis of the 10 kV three phase asynchronous motors.
