摘　　要：对2起110 kV变压器套管介损异常案例进行分析。采用油色谱、绝缘电阻、10 kV常规介损、高电压介损与FDS试验结合,分析套管可能存在的缺陷,并对其中1起套管案例进行解体检查,找出缺陷的原因。所开展的案例分析可为发现变压器套管缺陷隐患提供思路与参考。In this paper,two cases of abnormal dielectric loss of 110 kV transformer bushing are analyzed.The possible defects of bushing are analyzed by combining oil chromatography,insulation resistance,10 kV conventional dielectric loss,high voltage dielectric loss and FDS test.One case of bushing is disassembled and checked to find out the cause of the defect.This paper can provide ideas and references for finding hidden defects of transformer bushing.

关 键 词：变压器套管 FDS试验 高电压介损
