| 摘 要： | 对GIS(SF6气体绝缘全封闭组合电器)变电站中产生的高频暂态过电压，即陡波前过电压的产生原因、分类及危害性进行了介绍，以2个典型变电站为实例，采用EMTP计算和现场测试相结合的方法对GIS内部陡波前过电压及外部陡波前过电压进行研究，总结出一种新的确定GIS中陡波前过电压水平的方法，并提出合理化保护措施和建议。

| Abstract: | This paper describes the reason, classification and harmfulness of high frequency transient overvoltage that is named as very fast front overvoltage (VFFO) generated in gas insulated switchgear (GIS). Taking two typical substations as example, internal and external VFFO of GIS have been studied by using the combination of EMTP calculation and site measurement. A new method to determine VFFO level has been summed up and reasonable protection measure and suggestion are provided. |
