| 摘 要： | 建立了GIS（Gas Insulator Switchgear气体绝缘体全封闭组合电器）局部放电模型，通过在GIS腔体盘式绝缘子上制作人工气泡模型，运用脉冲电流和气相色谱分析检测两种方法对GIS内局放进行了检测。获得了绝缘缺陷局部放电的分布图谱和局部放电时SF6气体分解组分。最后，通过曲线拟合研究了绝缘气泡缺陷下SF6放电各分解组分的变化规律。

| Abstract: | This paper established the GIS partial discharge model, made artificial bubble model on GIS cavity disk insulator, and tested GIS partial discharge by pulse current and gas chromatography. The distribution spectrum of insulation defect partial discharge and SF6 dissociation component during partial discharge were acquired. Finally, by curve fitting, this paper researched the change rule of SF6 discharge dissociation component under insulation bubble defect. |
