The concentrations of CO2, CF4, thionyl sulfide (SOF2), sulfuryl fluoride (SO2F2), disulfuryl decafluoride (S2OF10), sulfur dioxide (SO2) and sulfureted hydrogen (H2S) were in partial normal distribution. The concentrations of CO2, CF4, SOF2, SO2F2, S2OF10 were all below 0.1%; the concentrations of SO2 were below 3μL/L; the concentrations of H2S were below 1μL/L. The SF6 byproducts concentrations in 500kV GIS were lower than those in 220kV GIS. The SF6 byproducts concentrations were lower in GIS that have been operating longer. The SF6 byproducts concentrations were significantly different in equipment from different manufacturers.

结果显 示：SF6 GIS 中CO2、CF4、氟化亚硫酰（SOF2）、氟化硫酰（SO2F2）、十氟化二硫酰（S2OF10）、二氧化硫（SO2）和硫化氢（H2S）都成偏正态分布，其中，CO2、CF4、SOF2、 SO2F2、S2OF10 的含量均小于0.1％，SO2 的含量均低于3μL/L，H2S 的含量均低于1μL/L.500kV GIS 设备中SF6 分解产物含量低于220kV GIS 设备；运行时间越长，设备中SF6 分解产物的含量越高；不同设备厂商的GIS 中 SF6 分解产物含量有显著性区别。

The concentrations of CO2, CF4, thionyl sulfide (SOF2), sulfuryl fluoride (SO2F2), disulfuryl decafluoride (S2OF10), sulfur dioxide (SO2) and sulfureted hydrogen (H2S) were in partial normal distribution.
