电压互感器烧毁的原因分析与解决方案研究

Cause Analysis and Solution Study of Voltage Transformer Burning

在中性点不接地系统中,电压互感器的烧毁事故常因铁磁谐振所引发,为有效预防电压互感器的烧毁,基于对铁磁谐振的现象、分析了铁磁谐振的形成条件以及谐振种类,对各种防范铁磁谐振产生措施进行了研究,并提出了一些防范电压互感器烧毁的方案,通过综合应用这些防范电压互感器烧毁的方案,可更好的预防电压互感器发生烧毁事故。

In the ungrounded system of neutral point,the burning accident of voltage transformer is often caused by ferromagnetic resonance.In order to effectively prevent the burning of voltage transformer,the author analyzed the formation of ferromagnetic resonance based on the phenomenon of ferromagnetic resonance.Conditions and types of resonance,research on various measures to prevent ferromagnetic resonance,and put forward some solutions to prevent voltage transformer burnout.By comprehensively applying these solutions to prevent voltage transformer burnout,voltage transformers can be better prevented.
