本标准代替GB/T 7601-1987《运行变压器油水分测定法(气相色谱法)》。
本标准规定了变压器油、汽轮机油和氢冷发电机组用密封油中水分含量的气相色谱测定法。
本标准适用于变压器油、汽轮机油和氢冷发电机组用密封油中水分的测定。
其他油中水分含量的测定也可参照本标准。
本标准与GB/T 7601-1987比较,有以下主要变化:
———将适用范围由变压器油扩展到汽轮机油、密封油;
———保留了原方法原理;
———规定了气相色谱仪需专用或具有汽液分离和收集残油的功能;
———推荐了常用色谱气路流程和固定相及色谱操作参考条件;
———推荐了分析用标准油样,去掉了原标准推荐的用饱和正庚烷作标准工作曲线和换算结果的步骤;
———规定了操作步骤;
———给出了结果计算方法;
———提出了方法的精密度。
Scope
This standard specifies the gas chromatographic method for the determination of moisture content in transformer oil, steam turbine oil and seal oil for hydrogen-cooled generator sets. This standard applies to the determination of moisture in transformer oil, steam turbine oil and seal oil for hydrogen-cooled generator sets. The determination of water content in other oils can also refer to this standard.
