| 摘 要： | 雷电波沿着输电线路侵入变电所,会对变电所GIS设备造成很大威胁.在平班水电站的基础上,建立了以架空线为GIS出线的模型,通过雷击塔顶的雷击方式,利用ATP-DRAW程序计算了当雷电波侵入平班水电站GIS系统后,在各电气元件中引起的雷电过电压,验证了平班水电站的避雷器配置方案是合理的.文中还讨论了感应电压及杆塔冲击接地电阻对过电压的影响.

| Abstract: | Lightning surge intrudes substation along transmission line,which is the threat to the GIS equipments within substation.Based on the Pingban Hydropower Station,this paper makes a model which takes overhead line as the ingoing line of GIS.Through lightning stroke on the top of a tower,the lightning overvoltages of the equipments within the station are calculated,which proves that the Hydropower Station's scheme of mental oxide arrestor is correct.This paper also discusses the induction voltage and the impulse ground resistance's affection to the lightning overvoltages. |
