气压对SF_6正极性直流局部放电分解特性的影响及作用机制
|
摘要
为了研究不同GIS内部气压对SF_6正极性直流PD分解组分的影响,本文对SF_6正极性直流局部放电分解组分的影响机制进行了分析,搭建了正极性直流PD实验平台,研究不同气压下SF_6正极性直流PD分解组分的含量及生成速率。结果表明:在不同的气压条件下,4种特征分解组分(CF_4、SO_2F_2、SOF_2和SO_2)的生成量和生成速率存在明显的差异,其中SO_2F_2和SOF_2的含量最大,SO_2含量较少,CF_4含量最少。在保持气室体积和外部温度不变的情况下,SF_6初级分解产物SF_5、SF_4、SF_2等的生成量与气压大小成反比,使得在5组实验气压下,气压值越大,4种特征分解组分的生成量越少。
In order to study the influence of different pressure on the SF_6 decomposition components under positive DC partial discharge(PD) in GIS, the influence mechanism of SF_6 decomposition components under positive DC partial discharge was analyzed, and a test platform was set to research the content of SF_6 decomposition components and their generating rate under positive DC partial discharge at different pressure. The results show that under different pressure, there are obvious difference among the generating amount and generating rate of the characteristic components CF_4, SO_2 F_2, SOF_2, and SO_2. The content of SO_2 F_2 and SOF_2 is the highest, the content of SO_2 is followed by, and the content of CF_4 is the lowest. Under the same chamber volume and external temperature, the generating amount of the primary decomposition products of SF_6, including SF_5, SF_4, SF_2, is inverse proportion to the pressure, make the content of CF_4, SO_2 F_2, SOF_2, and SO_2 decrease with the increase of pressure.
