摘　　要：为了研究快速暂态过电压(VFTO)在气体绝缘金属封闭式组合电器(GIS)电压互感器上的传递特性,根据《GB20840.1-2010互感器通用技术要求》中对安装在GIS中的互感器的传递过电压限值及试验要求,研制了一套集B类冲击波的产生、控制及测量为一体的试验装置;基于该试验装置对110kV GIS用电压互感器进行了传递过电压试验,试验结果表明该B类冲击波测控装置能够满足IEC及国家标准要求,并得出GIS电压互感器的传递过电压具有线性传递特性的结论。In order to research the transfer characteristics of very fast transient overvoltage （VFTO） in gas insulatedswitch-gear （GiS） voltage transformer, a Class B wave monitoring device combining the generation, control andmeasurement of Class B to the shock wave into one has been developed in this paper base on the limits on GIStransformer＇s over-voltage and testing requirements in ＂GB20840.1-2010 Transformer General TechnicalRequirements＂. The transfer overvoltage experiment has been performed using this device to test the transmittedovervoltage of 110kV GIS voltage transformer, the result of which show that the device will meet the requirements ofIEC and the national standards. Moreover, the conclusion of the transfer overvohage of GIS voltage transformerpossesses a linear transferring characteristic has been obtained.
