典型吸附剂对GIS固体绝缘介质放电特征气体变化规律影响
|
摘要
为降低化学诊断法进行气体绝缘组合电器(GIS)内固体有机绝缘介质放电诊断时吸附剂的影响,通过设置沿面放电缺陷模型进行模拟试验,重点关注了活性Al_2O_3、KDHF-03等五种吸附剂对固体绝缘介质放电特征的影响。结果表明:典型吸附剂对含碳特征气体的整体吸附率均明显小于含硫特征气体,除对COS有一定吸附作用外(吸附率不超过40%),其他三种含碳特征气体(CF_4、CS_2和CO)基本不受吸附剂影响或影响较弱;利用特征气体CF_4含量的增长规律进行GIS有机绝缘介质绝缘缺陷诊断可忽略吸附剂影响,吸附剂存在条件下CS_2仍可有效判断放电是否与有机绝缘介质相关,COS的产生标志着有机绝缘介质放电程度进一步严重,且吸附剂的作用在一定程度上降低了COS反映放电程度的灵敏性;利用诊断特征量C(COS+CS_2)/C(SO_2F_2)呈现的与放电程度的正相关性判断GIS内固体有机绝缘介质放电缺陷严重程度可有效降低吸附剂的干扰。
In order to reduce the influence of adsorbents on the chemical diagnostic method used for the insulation status estimate of solid organic dielectric in gas insulated switchgear(GIS), creeping discharge model was set up on a small apparatus, to study the variation of characteristic gases in different conditions, including adding five different kinds of adsorbents(activated alumina, KDHF-03, etc) separately, The results show that the adsorption rate by different adsorbents on the carbon-containing gases is obviously smaller than that of the sulfur-containing gases. In addition to the adsorption rate on COS is not more than 40%, and the other three kinds of carbon-containing gases(CF_4, CS_2 and CO) are not affected by adsorbents or are weakly affected; and the influence of adsorbents can be neglected to diagnose insulation defects related to organic dielectric, according to the growth of characteristic gas CF4 in GIS. In the presence of adsorbent, CS_2 can also be applied to judge whether the discharge is related to solid organic dielectric. The generation of COS indicates that the discharge level on the organic dielectric deepens, whereas the sensitivity of COS reflecting on creeping discharge level is decreased to some extent because of the influence of adsorbents. C(COS + CS_2)/C(SO_2 F_2), as a new diagnostic characteristic is proposed, shows a positive correlation with the degree of discharge, which can effectively reduce the interference of adsorbents to determine the seriousness of the discharge defects involving solid organic dielectric in GIS.
