摘　　要：对SF6气体内的氮气、水分、氧气和四氟化碳4种气体杂质在放电情况下对SF6气体分解产物的影响进行了详细的试验研究。结果表明,在低能量放电情况下,氮气和四氟化碳含量变化对SF6气体分解产物影响较小,水分和氧气杂质能促进SF6气体分解产物的生成。研究结果为通过SF6分解产物判断设备故障提供参考。The influence of gas impurity including N2, H2O, O2 and CF4 on SFs gas decomposed products was studied by de- tailed experiment. The results show that the content of Nz or CF4 has limited influence on the formation of SF6 decomposed products, but H2O or O2 has great influence on making SF6 decomposed products, in the case of low-energy discharge. The re- sults will provide reference for fault diagnosis of GIS equipments through SF6 decomposed products.
