摘要

近年来

因变压器油中的腐蚀性硫与铜绕组反应生成硫化亚铜而导致多起高压设备发生故障

如何应对该问题已成为当前电力部门主要关注的热点之一。笔者详细介绍了目前国内外关于变压器油中腐蚀性硫已有的检测标准

总结了已被报道的对变压器油中腐蚀性硫可进行定量分析的不同测量方法

并对上述检测标准及测量方法进行了综合比较及相关验证

主要得出以下结论:对变压器油中的腐蚀性硫进行定性检测时

油中氧气会影响检测结果

用纸包铜线作实验材料比用裸铜线得出结果更准确;利用高效液相色谱（HPLC）技术可以有效测量变压器油中腐蚀性硫—二卞基二硫（DBDS）的浓度。以上结论为完善当前电力部门及相关制造企业对投运前变压器油所进行的腐蚀性硫检验工作提供了辅助及参考依据。

Abstract

Recently

many faults of high voltage electric equipments happened due to the copper sulfide

which was formed by corrosive sulfur in transformer oil reacting with copper windings.Solving this problem has become the main concern for electric departments at present.In this paper

the existing standard test methods and measuring techniques are compared

and some related experiments are performed to verify these methods and techniques.The conclusion can be drawn as follows: when conduct a qualitative analysis of corrosive sulfur in transformer oil

the oxygen content in oil will influence the test results

and paper-wrapped copper wire can help to achieve more accurate results than bare copper wire.HPLC is an effective technique to measure the concentration of dibenzyl disulfide（DBDS） in transformer oil.This study may favor the measurement of corrosive sulfur in transformer oils by electric power enterprises and related manufacturers before putting transformers into operation.
