摘要
针对某110kV变压器发生的跳闸故障,采用频率响应分析、油色谱分析、绝缘电阻检测等手段进行原因分析,并通过吊罩解体检查验证,认为该故障的主要原因是套管顶部接线座松动、胶垫密封不良导致变压器进水,造成变压器内部短路,提出相应的改进措施及建议。
For the trip of a 110 kV transformer failure occurred, Frequency Response Analysis Technology, Oil Chromato graphic Analysis, Detection means such as insulation resistance, Cause analysis, By hanging out transformer core, Disintegration and check, Think the main reason for the failure is loose sleeve top Terminal Block, Sealing pad transformer caused by bad water, Cause an internal short circuit transformer, And proposed improvements corresponding preventive measures.
