摘　　要：针对腐蚀性硫测试所采用定性方法的片面性和主观性,提出采用铜粉腐蚀法对变压器油中腐蚀性硫的质量浓度进行定量分析,具体操作是:将过量铜粉与尼纳斯新油、尼纳斯运行油、三菱油和无腐蚀性的克拉玛依4种试验油混合后加热到一定的温度,通过不同的试验时间,测试反应前后油中总硫的质量浓度,其差值为与铜粉发生反应的腐蚀性硫的质量浓度,由此确定定量分析方法的最佳反应温度和反应时间。Aiming at one-sidedness and subjectivity of quantitative method adopted for corrosive sulphur test, the paper proposes to quantitatively analyze mass concentration of corrosive sulphur in transformer oil with copper powder corroding technique. The specific steps are： to mix excess copper powder with four kinds of test oil, such as clean Nynas oil, Nynas run- ning oil, MITSUBISHI oil and corrosion-free Karamay oil, and heat them up; test gross mass concentration of sulphur in transformer oil before and after the reaction through different test time, and the difference value is the mass concentration of corrosive sulphur that reacts with copper powder. Therefore, the optimum reaction temperature and reaction time of quantitative analysis are determined.
