摘　　要：本文阐述了电气设备内SF6气体在异常放电和过热情况下分解产物生成的机理,通过几起典型的故障实例分析,初步探讨了气体分解产物的组分和含量在现场SF6电气设备故障诊断和定位中的应用情况,为今后发现运行中的SF6电气设备的潜在故障提供了参考依据。The decomposing principle of SF6 in the abnormal conditions including discharging and o- ver-heating is described in this paper. Through fault analysis of some typical examples, the components and contents of the gaseous decomposition products in fault diagnosis and location of SF6 electrical equipments are discussed preliminarily, which can provide reference basis for finding potential fault of the operating SF6 electrical equipment in the future.
