摘要
针对典型750 kV变电站GIS接线进行了多种出线和操作方式的计算研究,给出了隔离开关有合分闸电阻时的较大过电压幅值和频率,得出了不同厂家结构尺寸参数、GIS结构及内外部设备对750 kV变电站GIS中VFTO幅值和频率的影响。
Calculation and study are conducted for different outlets and operation modes in the light of GIS wiring in typical 750kV substation. The great overvohage amplitude and frequency are given when disconnected switchgear has switching resistor. The effect of different manufacturer＇s GIS dimension and parameter, GIS structure, internal ＆ external equipment upon VFTO amplitude and frequency in 750kV substation GIS are presented as well.
