摘要
从过电压、热效应以及局部放电三个方面叙述了变频电机绝缘所承受的电动力、热应力等和普通电机的不同,分析了变频电机绝缘损坏的原因。
Frequency withstanding electrodynamic effect and partial motor insulation a conversion motor insulation force and thermal stress. differs from general motor insulation in The differences in overvoltage, thermal discharge are described. The damage causes of the frequency conversion analyzed.
