测量变频牵引电机定子局部放电的新方法

New Method to Measure the Stators Partial Discharge of Frequency-control Traction Motor

介绍了一种测量牵引电机定子绕组脉冲局部放电的新方法,简要说明了它的特点、原理和方法,为变频电机定子绕组绝缘测试准确度的提高和制造缺陷的诊断提供了思路。

New method to measure partial pulse discharge of the stator windings of the traction motor was introduced. The features, principle and method were demonstrated briefly, providing a thinking way to increase the testing accuracy on the stator winding insulation of the traction motor and to diagnose the failure during manufacture. 0
