摘要
在10kV、35kV的中性点非有效接地系统中,由于变压器、电压互感器、消弧线圈等设备铁心电感的磁路饱和作用,激发产生持续的较高幅值的铁磁谐振过电压。通过对配电系统电压互感器频繁损坏的现象,简要阐述铁磁谐振的现象、危害,产生的条件及防范措施,总结了针对此类故障采取防范措施的一些运行经验。
Based on the phenomena of frequent damage about power transformer in electric power supply system, the phenomenon, hazards reasons and prevention neasures of ferroresonance were briefly illustrated. Some operation experiences of adoptiong prevention measures aiming at such failure were concluded.
