摘　　要：统计了2015—2019年内蒙古西部地区入网变压器油界面张力数据,不合格率分别为32.3%、34.0%、43.7%、65.5%、39.5%,均高于30%并呈逐年增长的趋势,认为新油精炼程度不够、添加剂超标和运行油在使用过程中老化产生醛类、酮类以及羧酸类物质是界面张力不合格的主要原因,提出采用吸附再生法对老化变压器油进行处理。According to statistics on the interfacial tension of transformer oil in western Inner Mongolia from 2015 to 2019,the unqualified rates are 32.3%,34.0%,43.7%,65.5%,39.5%,which are all higher than 30%and are increasing year by year.Insufficient oil refining,excessive additives,and aldehydes,ketones and carboxylic acids produced by the aging of the operating oil during using are the main reasons for the unqualified interfacial tension.Adsorption regeneration method is proposed to treat the aged transformer oil.
