摘    要:本文采用多柱自动切换气相色谱仪和真空全脱气装置对变压器和互感器用油中的气体进行了系统的分析,除可测定油中的氢、甲烷、乙炔、乙烯、乙烷、二氧化碳和一氧化碳等气体外,还可根据不同需要测定氮、氧以及C3和C4烃的含量。本方法已用于诊断变压器和互感器内部变化及故障。

关 键 词:脱气 气相色谱 变压器油 气体

Abstract:Over the years the analysis of gas in oil used intransformer has been developed into a valuable tech-nilque in transformer diagnostic.The compositions ofthe gas dissolved in the oil are determined by means ofgas chromatography. On the basis of the concentrationof the gases and the kind of oil it can be establishedwhether the phenomenon should be classified as anelectrical or a thermal defect.The gas-extraction apparatus, multi-columns au-tomatic switching of chtomatogtaphy,sample injectingunit and analysis system have been described.H_2,CH_4,C_2H_2,C_2H_4,C_2H_6,C_3H_8,C_3H_8,CO,CO_2,N_2,andC_3,C_4 gas dissolved in the oil can be analysed.
Keywords:Gas analysis  transformer oil  chro-matography
