摘 要: 根据故障时变压器内部油气量和电气量特征,按照相关标准和试验规程要求,以色谱分析和继电保护动作特性为主线,结合一台35 kV 变压器开关接触不良和一台220 kV 主变重瓦斯动作两个实例,对联合诊断方法的准确可靠性进行验证。实践结果表明:联合诊断可以准确地进行故障诊断和定位,具有良好的可行性和适用性。

Abstract: According to characteristics of oil-gas and electrical signals inside transformers when transformers faults take place and following the relevant standards and testing procedures requirements, the transformer fault combination diagnosis method was proposed based on taking the chromatographic analysis and relay performance as the main line. The combination diagnosis method has been verified by two examples of a 35 kV transformer switch poor contact fault and a 220 kV transformer heavy gas protection action. Practical results show that the combination diagnosis method could diagnosis faults and faults location accurately with good feasibility and applicability.
Key words: transformer; oil chromatogram; electrical test; fault location
