| 摘 要： | 环烷基油是生产高性能变压器油的优质原料,以此为基础油生产的变压器油其凝点一般都小于-40℃,而变压器油在使用过程中对凝点(即低温流动性)有着非常高的要求,凝点的高低直接影响着油品的物理化学性能及电器性能。而油品的低温流动性与其组成中的正构烃(蜡)含量密切相关,据有关

| Abstract: | The micro content and the C-distribution of micro normal paraffin hydrocarbon in naphthenic base transformer oil are analyzed and determined by GC-MS.The repeatability of the Quantitative analysis by mass chromatogram and internal standard method is high,and the recovery is 95%-105%.Normal paraffin hydrocarbons from C13-C23 were affirmed in naphthenic base transformer oil and their content is less than 1%. |
