气相色谱分析法在油浸式变压器预知诊断中的应用

Application of gas chromatography in maintenance of oil-immersed transformer

气相色谱分析法是供配电系统中常用的一种检测技术,通过采集少量变压器油样进行气体组分和含量分析来判断变压器的内部是否存在故障或者隐患。油浸变压器线圈和铁心全部安装在变压器箱内、浸没在变压器油中,无法直观观察线圈及铁心运行状态,运用气相色谱检测技术较好地解决了上述矛盾。本文采用这一方法针对具体案例开展跟踪分析很快发现设备隐患,为最终彻底处理设备隐患保障设备稳定运行提供了有效手段。

Gas chromatographic analysis is a common technique to detect oil-immersed transformers in operation.By collecting a small amount of transformer oil samples to analyze the gas composition and content in the oil,it can be judged whether there are faults or hidden dangers in the transformer.The coils and cores of oil-immersed transformers are all installed in transformer boxes and immersed in transformer oils,so it is impossible to observe the hidden trouble of transformer directly.The application of gas chromatography to transformer detection can fully solve this problem.In this paper,the gas chromatography was used in practice,and quickly discovered the hidden trouble of the equipment,which provided an effective means to deal with the hidden trouble of the equipment thoroughly and guarantee the stable operation of the equipment.
