| 摘 要： | SF6电气设备在电网中的应用越来越广泛,这些设备运行状态的好坏直接关系着电网的安全。根据SF6的化学性质与分解机理,利用SF6气体分解产物可以判断设备故障、推测可能存在缺陷。通过对SF6电气设备的日常监督,统计分析了SF6气体分解产物中特征组分(二氧化硫SO2、氟化亚硫酰SOF2以及硫化氢H2S)的生成情况,并以此为基础总结出了SF6电气设备放电故障诊断标准,提出了不同电压等级SF6电气设备分解产物检测周期。

| Abstract: | SF6 electric equipment is an important part of grid and has a closer relationship with the grid safety.Based on the chemical properties and decomposition mechanism of SF6,its decomposition products can be used for judging the fault of equipment.The yields of SF6 decomposition products were analyzed and summarized based on the routine supervision for SF6 electric equipment.The standard of fault diagnosis and the detection period for SF6 electric equipment were suggested. |
