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.
