气相色谱分析法在油浸式变压器故障诊断中的应用

Application of Gas Chromatography Method in the Fault Diagnosis of Oil- immersed Transformer

介绍了气相色谱分析法的基本原理,重点讲解各故障类型对应的气体特征,并运用气相色谱分析法及三比值判断法预判现场变压器故障,通过变压器吊芯验证了故障判断的正确性,避免了设备故障的扩大,确保各变压器稳定顺行。

This paper introduces the basic principle of gas chromatography method,focuses on the gas characteristics corresponding to various fault types. By using the gas chromatography method and three ratio judgment method,the transformer faults were predicted,and the accuracy of fault diagnosis was verified through transformer core,thus the expansion of equipment faults was avoided,and the stability of transformer was ensured.
