摘 要
变压器油中气体组分含量是检测变压器油品质量的重要指标。然而由于取样容器不规范,导致氢气和烷烃类含量测量出现偏差。研究发现与针筒样比较，瓶装样在室温条件下，7d内损失率达到100%。此外，瓶装样变压器油中的氢气和烃类气体在初始浓度不同时,室温下存放7d,作者发现不同浓度的氢气和乙炔气体损失率均达到95%以上,不同浓度的甲烷损失率达到80%以上,不同浓度的乙烷和乙烯损失率达到60%以上。

Abstract
The gas component content in transformer oil is an important indicator for detecting the quality of transformer oil. However, due to the non-standard sampling containers, there were deviations in the content of hydrogen and alkanes. Research had found that compared to syringe samples, bottled samples had a 100% loss rate within 7 days at room temperature. In addition, this article examined the residual gas content dissolved in transformer oil samples stored at room temperature for 7 days under different initial concentrations of hydrogen and hydrocarbon gases. It was found that the loss rate of hydrogen and acetylene gases at different concentrations reached over 95%, methane at different concentrations reached over 80%, and ethane and ethylene at different concentrations reached over 60%.
