为研究特高压气体绝缘开关设备（gas insulatedswitchgear,GIS）中的特快速瞬态过电压（very fast transientovervoltage,VFTO）规律,需要建立全尺寸的真型模拟试验回路。计算了1000kV GIS变电站和模拟试验回路在不同接线方式下的VFTO,指出1000kV GIS的VFTO模拟试验回路宜带有分支母线,比国家标准和IEC标准规定的无分支母线的简单试验回路更严格,从而提出新的VFTO试验回路,并推荐了测点布置方案和试验隔离开关型式。对所建成的VFTO试验回路进行试验,结果表明：无论是从VFTO实测波形还是从统计规律上看,试验回路均达到了设计的预期,对研究VFTO的特性发挥了重要作用。

For fully understanding the characteristics of very fast transient overvoltage（VFTO） in ultra high voltage（UHV） gas insulated switchgear（GIS）,it is necessary to set up full-scale 1 000 kV GIS Test circuit.Based on the computer simulation of the VFTO and comparison between different circuit schemes of UHV GIS substation and planned 1 000 kV GIS test circuit,it is suggested that the 1 000 kV GIS test circuit should be equipped with a branch bus which could cause more severe VFTO than that tested without the branch bus.A new 1 000 kV GIS test circuit with a branch bus,different from the one presented in national or IEC standards,is put forward.Investigation and designing were made for the test circuit with the arrangement of measurement points and the selection of the disconnectors with different switching speeds.The test results obtained with the constructed GIS test circuit show that the influence of branch bus on VFTO is in accordance with the anticipation of design,either in waveforms or in statistical regularity.The test circuit showed an excellent performance in the research on 1 000 kV GIS VFTO.
