摘　　要：变压器油中溶解气体分析是一种诊断变压器故障的有效方法。就5种不同的变压器油(环烷基和非环烷基)经不同温度和不同时间老化处理后的产气特性进行了比较,以便为变压器的安全运行提供数据支撑。5种变压器油产生氢气,一氧化碳,甲烷,乙烯及二氧化碳的趋势均随着老化温度的升高而增加。加氢精制深度较低的环烷基变压器油的产气趋势变化相对较快。变压器油的产气趋势与基础油精制深度有关,与基础油组成无关。Dissolved gas analysis in transformer oil is an effective method to diagnose transformer faults.The gas production characteristics of five kinds of transformer oils(naphthenic and non-naphthenic)after aging treatment at different temperatures and for different times are compared to provide data support for the safe operation of transformers.The production of hydrogen,carbon monoxide,methane,ethylene and carbon dioxide by the five transformer oils increased with the increase of aging temperature.The gas production trend of naphthenic transformer oil with low hydrofining depth changed relatively quickly.The gas production trend of transformer oil is related to the refining depth of base oil and has nothing to do with the composition of base oil.

关 键 词：基础油组成 溶解气体 老化温度 老化时间
