摘要
通过对发生跳闸事故的一台110kV变压器检测、试验,采用溶解气体色谱分析法分析该变压器油中溶解气体的成份、特征气体含量、变化趋势及三比值,进行故障识别、故障类型和状况诊断、故障部位估算,诊断其内部是否存在故障及故障的性质和严重程度。
According to DGA(Dissolved Gas Analysis),this paper analyze elements、content of typical gas、varying trend and three of the dissolved ges which comes from a 110kV transformer when tripped,so as to distinguish the hitch,diagnose hitch's types and conditions,estimate the positions,judge possible inner hitch,charecteristics and seriousness of the hich.
