高效液相色谱法测定变压器油中糠醛含量的试验研究

电力系统中许多变压器在运行多年，其绝缘纸经过热的长期作用往往会出现失去弹性、机械强度下降等老化现象，油中糠醛分析是诊断变压器纸绝缘老化的有效方法。文章结合油中糠醛检测的原理，对利用高效液相色谱法分析变压器油中糠醛的方法，如分离操作条件选择、定性定量分析、从油中提取糠醛的方法等做了系统研究，同时对青海省电力公司系统在役运行的330kV主变、电抗器糠醛含量进行了普查、分析和评价。

Study of High performance Liquid Chromatography Detecting Furfural Content in Transformer Oil

After years operating and heating effect,the transformer of electric power system sometimes occurs aging problems of losing elasticity and mechanical strength decline,and then the furfural content in oils analysis is an effective method to diagnose transformer insulating aging.The paper makes a systematical study on detecting method of furfural content in transformer oils through using high performance liquid chromatography,including condition select of separation,qualitative and quantitative analysis,and f...
