摘　　要：论文对两起110kV变压器进水受潮故障进行了详细的诊断分析，通过应用“频率响应分析技术”、油色谱分析、直流电阻等检测手段对变乐器进行了令面检查，分析认为两起故障都是由于套管顶部胶垫密封不良导致变压器进水，造成变压器内部短路故障，高压绕组局部严重烧损。吊罩解体证实了分析的正确性，同时提出了对应的防范改进措施。In this paper, two water wet l l0kV transformer failure to perform detailed diagnostic analysis, through the application of ＂frequency response analysis technology＂, oil chromatographic analysis, the DC resistance of the transformer and other detection means to conduct a comprehensive inspection, analysts believe that the two failures are due to top of the casing seal pad transformer caused by bad water, causing the transformer internal short circuit fault, voltage winding local severe burning.Hanging hood disintegration confirmed correctness of the analysis, and proposed the corresponding preventive improvement measures.
