摘要
对110 kV川口变电所2#主变,在2004年8月19日发生的一起由35 kV输电线路短路故障造成对2#主变冲击,使2#主变严重受损事故,并结合2#主变事故前、后的电气试验以及吊罩解体检查等情况的综合分析,阐述了该主变冲击受损的原因,提出了在变压器制造工艺等方面的预控措施。
Aiming at the 35kV trammission line short-circuit accident of ll0kV Chuankou substation on Aug. 19 Of 2004 which induced the impact on 2# main transformer and made it seriously damaged, the paper expounds the damage reason combining with the comprehensive analysis of the electric test of the 2 # main transformer before and after the accident, and the disaggregation check of the suspending cover, as well as proposes some relevant preventing control measures on the manufacturing technique of the transformer.
