摘　　要：为更准确反映隔离开关操作过程中的特快速暂态过电压(VFTO)的全波形,建立了包含击穿电压、燃弧电阻、断口电容等动态因素模块的特高压GIS隔离开关多次重燃模型,为仿真隔离开关多次重燃下的VFTO提供了研究思路。To accurately reflect the entire waveform of very fast transient over-voltage （VFTO） during opera-tion of disconnect switches, a multiple-restrike model of UHV GIS disconnecting switches including several dynamic factors such as breakdown voltage, arcing resistance and fracture capacitance is built, providing ideas for investigating VFTO with multiple restrikes of simulated disconnecting switches.

关 键 词：隔离开关 多次重燃 击穿电压
