摘要/Abstract

摘要： 变压器绝缘油中添加金属钝化剂可有效缓解腐蚀性硫对变压器的腐蚀。为掌握广东电网主变压器（主变）绝缘油中金属钝化剂含量变化情况,采用高效液相色谱法对广东电网添加金属钝化剂的208台主变绝缘油中金属钝化剂质量分数进行了普查。结果表明,金属钝化剂质量分数明显降低的主变有60台,其中降低幅度较大的有19台。参考国际相关标准,提出了变压器绝缘油中添加金属钝化剂后运行监督的措施。普查结果可为制定我国变压器绝缘油金属钝化剂添加和运行标准提供参考。

Abstract: The metal passivators added in the transformer insulation oil can effectively relieve the corrosion caused by corrosive sulfur. In order to fully understand the changes of the metal passivator content in the mineral insulating oils of transformers in Guangdong power grid, the content of metal passivators in 208 transformers was traced quantitatively by virtue of the High Performance Liquid Chromatographic (HPLC) method. The census results show that the metal passivator content in 60 transformers decreases substantially. In particular, 19 of them exhibit significant changes. Based on the relevant international standard, the operational supervision treatment of the transformer insulating oil with metal passivator additive is proposed. The census results can provide references for the establishment of standards on metal passivator additions and corresponding operations in our country.

Key words: transformer insulating oil, metal passivator, high performance liquid chromatographic (HPLC), Irgamet 39
