高压防爆电机线圈匝间绝缘耐压试验中线圈位置的影响及其消除方法

Influence of Winding Position to Withstand Voltage Test on Interturn Insulation of High-voltage Ex Motor and Its Elimination Measure

在用RZJ型匝间仪做匝间耐压试验时,用常规方法经常会出现误判,文章介绍匝间仪的测试原理,并对出现误判的现象工作了详细分析,最后,通过理论分析和试验验证,探索出了匝间仪用于匝间耐压试验测试时的正确方法。

A misjudgment is often made during withstand voltage test with conventional method and RZJ turn - to - turn instrument. In this article, test principle of turn - to - turn instrument is introduced firstly. It analyses the cause of misjudgement when do the withstand voltage test with the turn - to - turn instrument. In the end, it searches out the correct method of withstand voltage test with the turn - to - turn instrument by theoretical analysis and experimental verification.
