摘要:为了研究VFTO在GIS电压互感器上的传递特性,本文根据《GB20840.1-2010互感器通用技术要求》对于安装在气体绝缘金属封闭式组合电器(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;通过该试验装置对110kV GIS用电压互感器进行了传递过电压试验,试验结果分析表明该B类冲击波测控装置能够满足IEC及国家标准要求,并初步得出GIS用电压互感器的传递过电压具有线性传递特性。

Abstract:In order to research the transfer characteristics of VFTO in GIS voltage transformer, this paper developed a Class B wave monitoring device which combined the generation of Class B to the shock wave、control and measurement into one, base on the limits on GIS transformer’s over-voltage and testing requirements in 《GB20840.1-2010 transformer General technical requirements》.Using this device to test the transmitted overvoltage of 110kV GIS Voltage transformer, the result showed that the device not only can meet the requirements of IEC and national standards, but also come to a conclusion that over-voltage transmission of GIS voltage transformer have a transfer characteristic.
