摘　　要：针对某电网公司22台变压器油中金属钝化剂不足的问题,采用自主研发的金属钝化剂添加装置添加金属钝化剂,并通过定期取样检测金属钝化剂含量和腐蚀性硫含量对添加效果进行验证。结果表明:添加金属钝化剂可以有效缓解腐蚀性硫对变压器的腐蚀,并指出了添加金属钝化剂过程中防止漏油、防止空气混入、控制注入流量及防止污染物进入等关键性问题。Aiming at the lack of metal passivator in oil for 22 transformers in a power grid company, a self-developed metal passivator adding device was used to add metal passivator, and the adding effect of metal passivator was verified by sampling and detecting the metal passivator content and corrosive sulfur regularly. The results show that adding metal passivator can alleviate the corrosion of corrosive sulfur to transformer effectively, and the key problems during the adding process of metal passivator are pointed out, which are preventing oil leakage, preventing air mixing in, controlling injection flow, and preventing pollutants mixing in.
