摘要
目前变频器与长电缆联接的应用已遍及油田、水电等领域 ,同时电机的高压绝缘破损失效现象也越发引起相关行业的关注 ,文章在对电机失效现象的机理进行分析的同时 ,给出几种在实际中切实可行的方法来防止电机进一步的失效。
The application of new generation variable frequency drives in the inverter section with motors connected by long leads has been a source for concern and expense. Motors controlled by VFD's installed some distance away often fail due to high voltage-induced insulation breakdown. This paper will offer a concise analysis of this phenomenon. It will also recommend some practical solutions for correcting existing problems and for protecting against future failure.
