摘要
基于变压器老化机理,引入"基于电网状态评估的风险防范管理体系",讨论了如何采用油气分析数据对变压器的运行工况进行评估,以及能够反映电力变压器运行工况的健康指数、故障发生概率及剩余使用寿命的计算方法。运用该方法对广州供电局的电力变压器进行了状态评价,事实证明变压器实际运行情况与评价结果基本一致。
Base on the fatigue mechanism of transformer, the essay introduces Condition Based Risk Management （CBRM） methodology and puts an emphasis on the discussion of how to assess the condition of transformer using the analysis data of oil and the mixture gas of oil, and the caculation of indexs, including health index, probability of failure and end of life, which could directly reflect the overall condition of power transformer. Conduct a assessment of power transformer using the way in the essay for GuangZhou Power Supply Bureau, the output proves that the methodology in this essay could assess the condition of power transformer precisely.
