| 摘 要： | 为了探讨GIS内不同绝缘缺陷与对应SF6气体分解组份之间的联系,在自建的SF6气体分解试验平台上,构建了两种常见的局部放电缺陷模型,并借助气相色谱仪,对气体组份进行96h的放电跟踪监测。结果显示,两种绝缘缺陷在局部放电发生时,都伴随有SF6气体的分解,检测到的主要分解产物均有SOF2,且其体积分数都随时间的延续而呈现出饱和增长的趋势,但两种缺陷下SOF2的产气特性存在明显差异,使SF6气体分解组份具有不同特征,可以对此两种缺陷进行辨别。

| Abstract: | In order to determine the relationship between different insulation defects and their decomposed components of SF6, two typical defect models of partial discharges were constructed and the decomposed components were detected for 96 hours with the gas chromatography. The results show that two types of insulation defects can generate decomposed components whose main component is SOF2 and the volume of SOF2 increases with the time. However, the characteristic of generating SOF2 of the two types of experiments ... |
