Gaoya dianqi, 1999 [问]SF6气体中的水分会带来那些危害?[答]水分的危害最主要的是在电弧作用下SF6气体产生的反应.在电弧或电晕的作用下,SF6气体将被分解为SF4,SO2F2（氟化硫酰）,SOF2（氟化亚硫酰）,HF（氢氟酸）和SO2等有害物质.生成物HF是所有酸中腐蚀性最强的.SO2遇水会生成亚硫酸H2SO2,它也是一种腐蚀件物质.由此看来如果SF6气体中含有水分,不仅会降低设备的绝缘强度而且危害人体健康.另外SF6气体中混杂的水分通常以水蒸汽形式存在,在较低温度下,水蒸汽可能凝结成露附着在零件表面 ...

Gaoya dianqi深度挖掘SF6分解产物携带电热腐蚀信息有助于提升GIS设备潜伏故障诊断精确度。研究六氟化硫—环氧树脂体系（SF6-epoxy）热分解反应，阐明碳基特征分解产物与绝缘材料降解对应关系，可有效解决特征组分单一性与来源多样性之间矛盾。文中采用同步热重/差示扫描量技术系统测量了SF6-epoxy热分解过程，表征了3个特征热解阶段的温度范围与放热量。在线气相色谱指认了9种碳基、硫氧分解产物。根据SF6-epoxy体系热解的全景反应历程，CO2可作为判定环氧树脂高温（>500 ℃）热腐蚀劣化的特征分解组分 ...
