摘要
对几台变压器油介损值超标原因及铜含量成因进行分析,指出油中铜含量异常是引起油介损值增大、绝缘电阻下降的主要原因。通过试验室各种净化处理试验,寻找处理变压器油铜金属异常的最佳方案,并应用于实际,取得明显效果。
The cause of Cu content abnormity and dielectric loss in several transformers oil were analyzed, The increasement of transformer oil dielectric loss and the reduction of insulation resistance were the main reason. Various purify tests were used to find the best treatment scheme for abnormal Cu content in transformer oil and had an obvious performance when applied in practice.
