摘要

对一起35 kV系统铁磁谐振引发站用变爆炸事故进行了分析

提出造成该起事故的原因是电压互感器发生铁磁谐振引起的母线电压的升高造成了站用变系统绝缘破坏

进而了引发后续的短路故障。为了避免类似事故的发生

在35 kV母线电压互感器一次中性点安装了非线性消谐装置

投切35 kV母线和电容器组正常

抑制铁磁谐振效果良好。

Abstract

A 35 kV transformer explosion accident caused by ferromagnetic resonance was analysed. It was found that the increase of the bus voltage due to ferromagnetic resonance of the potential transformer（PT）destroyed the 35 kV transformer’s insulation system

resulting in subsequent short-circuit fault and the following accident. In order to avoid this kind of accident

a nonlinear harmonic elimination device was installed at the 35 kV PT neutral point

thus the 35 kV bus and capacitor operate normally

and the ferromagnetic resonance is suppressed perfectly.
