摘要
针对一起220 k V变压器投运过程中有载分接开关烧损事故进行了分析,经现场检查与返厂解体,确认事故原因为变压器油含有杂质导致放电击穿,避免了事故的进一步发展,为今后220 k V变压器安全运行和技术监督积累了经验。
A 220 k V transformer＇ s on- load decomposition switch burn- out accident is analyzed,through on- site inspection and returned disintegration,the cause of the accident is identified as transformer internal discharge and breakdown caused by impurities in oil,the accident further development is avoided. The experience for the safe operation and technical supervision of the 220 k V transformer is accumulated.
