摘    要:采用高效液相色谱法对宁夏电网110 kV以上百余台在役电力变压器和互感器设备油样中的糠醛含量进行普查检测。根据糠醛普查含量检测结果,确定了变压器运行年限、绝缘纸老化速度与糠醛含量呈直线的关系。通过试验提出某主变压器不明杂峰出现与变压器故障具有紧密关系的观点,为今后研究变压器老化故障的判断提供了第一手资料。

关 键 词:变压器    糠醛    检测

Abstract:Using high effective liquid chromatography make census and detection on furfural con?tent in hundreds of transformer mutual inductor equipments oil for aabove 110 kV Ningxia PowerGrid, Based on the detection results of furfural content, determins the service life of transformer opera?tion and ageing speed of insulated paper show straight-line relationship with furfural content. The testshows that unnamed pear appearing in a main transformer has close relationship with transformer fail?ure, which provides the first hand material for old ageing failure diagnosis of the transformer.
