孝感电网主变变压器硫腐蚀普查试验研究

摘要

文中通过对孝感电网主变普查,找出了孝感电网220 kV主变油中铜含量与主变负荷、油中钝化剂、腐蚀性硫含量和总硫含量的关系,分析了五者之间的规律.通过普查,对孝感电网油中硫腐蚀风险提出了建议.%In this paper, the main transformers of Xiaogan power grid are surveyed to find out the Copper content in oil, the load of main trans formers, the passivator and corrosive sulfur content and high total sulfur content of the transformer oil, and to analyze the law among the five.Based on the investigation, some suggestions are put forward for the sulfur corrosion risk in Xiaogan power grid.
