摘　　要：“滤芯”对有载分解开关滤油装置非常重要,然而2020年11月在完成某220kV两个主变的开展有载分解开关吊芯检修、有载分解开关绝缘油滤油及其有载分解开关滤油装置滤芯更换工作后,2021年3月该站后台先后出现2个主变轻瓦斯告警事件,为此本文考虑“滤芯”工作的影响,提出了5个可能性原因,为后续深入分析提供了方向性指导。The“filter element”is very important for the oil filter device of the on-load decomposition switch.However,in November 2020,the maintenance of the hanging core of the on-load decomposition switch of a 220kV two main transformers,the insulation oil filter of the on-load decomposition switch and its on-load decomposition were completed.After the replacement of the filter element of the switch oil filter device,two main transformer light gas alarms occurred in the background of the station in March 2021.For this reason,this article considers the impact of the“filter element”work and puts forward 5 possible reasons for subsequent in-depth analysis Provides directional guidance.
