摘要
GIS中隔离开关操作时产生的特快速暂态过电压对电力系统及其设备的绝缘具有巨大的破坏力,本文提出了采用铁氧体来抑制GIS中隔离开关操作时产生VFTO的方法,分析铁氧体抑制VFTO的优点,对VFTO的抑制效果进行了实验研究和仿真分析,探讨了具有理想抑制效果的铁氧体参数的具体要求和对理想抑制参数的铁氧体尺寸的估算方法。
The insulation of apparatus in the power system is often broken by the very fast transient overvoltage （VFTO） which is caused by the operation of disconnector in gas insulate substation （GIS） In this paper, a new idea for the suppressing VFTO by ferrite is put forward, and the characteristic of ferrite is analyzed. The effect of suppressing VFTO by the ferrite is tested and simulated. The particular request of the ferrite parameters is discussed. A method for the estimating the size of ferrite is advanced.
