【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 addition of metal passivating agent in transformer insulation oil can effectively alleviate the corrosion of transformer caused by corrosive sulfur, so as to understand the variation of metal passivant content in insulation oil of main transformer (main transformer) in Guangdong power grid. The mass fraction of metal passivator in 208 insulating oils of main transformer was investigated by high performance liquid chromatography (HPLC) with metal passivator in Guangdong power grid. There are 60 main transformers whose mass fraction of metal passivator is obviously reduced, of which 19 are lower than others, referring to the international standards. The operation supervision measures after adding metal passivator to transformer insulating oil are put forward. The general survey results can provide a reference for drawing up the standard of metal passivating agent addition and operation of transformer insulating oil in China.
