摘要
本文中作者介绍了一起特高压直流换流站低端YD-A相换流变油色谱异常故障,通过油色谱数据、超声定位、现场进箱、返厂解体及仿真计算,确认了油色谱异常的原因,并提出了相应的建议及措施。
In this article,the author introduced an abnormal fault in the low-end YD-A phase rheological oil chromatogram of the UHV DC converter station.The oil chromatographic abnormality is confirmed through oil chromatographic data,ultrasonic positioning,field loading,disassembly and simulation calculation reasons,and put forward corresponding suggestions and measures.
