摘　　要：取气是将溶解气体从油中分离出来,是变压器油中溶解气体分析的关键步骤之一。通过对取气原理的分析研究,提出二次取气法可以应用于测定试验方法的回收率和变压器油样品的二次分析,分别从理论和样品检测实例两方面分析验证了该方法的可靠性。Degassing is separation of dissolved gas from the oil,which is one of the key steps in dissolved gas analysis in transformer oil.Through the analysis and research on the principle of degassing,it is proposed that secondary degassing method can be used to determine the recovery rate of the test method and the secondary analysis of transformer oil samples.The reliability of the method is verified from theoretical analysis and sample detection.

关 键 词：油中溶解气体分析 二次取气 回收率 二次分析
