气相色谱分析在变压器故障诊断中的应用

Application of gas chromatographic analysis in fault diagnosis for transformers

气相色谱分析就是通过分析变压器油中溶解气体的成分和含量，对变压器运行的情况进行诊断，根据气相色谱分析结果判断电力设备故障。介绍了气相色谱分析的机理和分析判断方法，并给出了应用实例。

Gas chromatographic analysis for trouble shooting is to carry out analysis of contents and compositions of gases dissolved in transformer oil to determine the operation conditions of the transformer. It is also possible to determine and identify the trouble that the power transmission equipment is suffering from. The article introduces the mechanism of the gas chromatographic analysis and ways for trouble identification and determination. The article also gives actual cases of the application of this technology.
