变压器重瓦斯动作后的分析诊断及处理

Treatment and Analysis After a Transformer Heavy Gas Operation

通过对发生重瓦斯动作的一台35kV变压器采用电气性能试验和油中溶解气体色谱分析法检测试验,阐述了如何进行故障诊断和识别,以及如何分析产生故障的原因和性质,并就制定故障处理方案,提出预防该类变压器损坏的反事故措施。

This paper uses the method of electrical performance test and resolved gas in-oil chromatography analysis to diagnose equipment fault through detection test to a 35 kV transformer which happened heavy gas operation,identify whether inside exist fault and fault property, examinations are made to diagnose whether result corre,~ct, reasons that cause fault are analyzed,fault handling scheme is work out,and counter accident measures are proposed to prevent this type of transformer damage.
