为验证我国特高压交流试验示范工程金属封闭开关设备（gas insulated switchgear,GIS）中隔离开关带电操作的安全性,在长治、南阳和荆门变电站对所有特高压GIS隔离开关进行了带电操作试验。在前期特高压GIS和复合型气体绝缘金属封闭开关设备（hypid gas insulated switchgear,HGIS）中特快速瞬态过电压（very fast transi-ent overvoltage,VFTO）实测研究基础上,开展现场典型运行方式下隔离开关带电操作,监测产生的VFTO和暂态壳体电位（transient enclosure voltage,TEV）。试验初步得出了特高压变电站实际VFTO和TEV水平及分布,结果表明：特高压GIS隔离开关的带电操作是安全的,但应注意产生的TEV对二次设备的影响,阻尼电阻能够有效抑制VFTO和TEV。带电操作试验的开展为今后特高压GIS隔离开关的带电操作提供了依据。

In order to verify the safety of switching of gas insulated switchgear （GIS） disconnectors energized in ultra high voltage（UHV） AC Pilot Demonstration Project, we experimentally investigated switching of all GIS disconnectors energized in Changzhi, Nanyang, and Jingmen substations, and monitored very fast transient overvoltage （VFTO） and transient enclosure voltage （TEV） generated . The tests results show that switching of UHV GIS disconnectors energized is safe, the effect of TEV on secondary equipment should be paid attention to, and damping resistor in disconnector can mitigate VFTO and TEV significantly, The tests provide technical support for the future switching of GIS disconnector energized in UHV substations.
