摘　　要：我国关于电机绝缘泄漏电流的标准是针对普通绕组制定的,而近年来出现一种新的可以被称为绕组端部表面全覆盖防晕结构的电机,其绕组的泄漏电流一般远远大于普通绕组的泄漏电流。本文通过实例分析,认为现行标准并不适合绕组端部表面全覆盖结构的电机。Current national standard for leakage current of electric machine was intended for usual windings. However, a new type of winding so called full corona protected winding arose in recent years, and it＇s leakage current is much larger than that of usual winding. Based on case studies, this paper pointed out that current standard are not suitable for full corona protected machines.
