摘要为提高化学诊断法用于气体绝缘组合电器(GIS)绝缘状态判断的准确度,需评估吸附剂对GIS内局部放电产生的特征气体的吸附特性影响。在小型模拟试验平台上设置针-板电极放电模型,研究了不放置吸附剂、分别放置5A、F-03和KDHF-03吸附剂时GIS局部放电特征气体的变化规律。试验结果表明:加入吸附剂后,SO₂、SOF₂、SO₂F₂、HF四种主要特征气体的含量有不同程度下降;5A型吸附剂对SOF₂、SO₂F₂的吸附能力明显弱于F-03和KDHF-03;3种吸附剂对SO₂、HF的变化规律影响基本一致,吸附剂存在时SO₂的含量处于定量限范围,且对HF的吸附率均超过96%。诊断特征量C(SOF₂)/C(SO₂F₂)可有效降低利用化学诊断法进行GIS绝缘状态评估时吸附剂类型带来的干扰。

Abstract：To improve the accuracy of the chemical diagnosis method used for estimating the insulation status in the gas insulated switchgear (GIS),it is important to assess effects of adsorbents on the evolving law of target gases under partial discharges in GIS.Different conditions,including without adsorbent and adding three different kinds of adsorbents (5A,F-03 and KDHF-03) separately,are taken into consideration to study the variation of target gases under partial discharges in GIS based on a needle-plate model on a small simulation test platform.The result shows that the contents of the four major target gases,i.e. SO₂,SOF₂,SO₂F₂ and HF,will decrease at different levels after adding adsorbents.The adsorption amount of SOF₂,SO₂F₂ by 5A is eminently less than that by F-03 and KDHF-03.Effects of different adsorbents on SO₂ and HF are almost the same.The adsorption rates on HF are all more than 96%,while the amount of SO₂ is with in the limit of quantification of gas analysis system after adding three different adsorbents.The factor C(SOF₂)/C(SO₂F₂) is proposed as a new diagnostic characteristic for partial discharges,which could reduce the influence of different adsorbents on assessing insulation condition by chemical diagnosis method in GIS.
