针对电力变压器绝缘状态评估的不确定性，提出一种新的基于区间层次分析法的电力变压器绝缘状态评估方法。建立了电力变压器绝缘状态评估指标体系，提出绝缘度的概念并划分了绝缘状态等级，根据区间层次分析法确定电力变压器绝缘状态评估指标的区间数权重，建立了基于区间层次分析法的电力变压器绝缘状态评估模型，结合区间数理论实现对电力变压器绝缘状态的评估。实例分析的结果表明，所建立的电力变压器绝缘状态评估模型是合理有效的。
針對電力變壓器絕緣狀態評估的不確定性，提齣一種新的基于區間層次分析法的電力變壓器絕緣狀態評估方法。建立瞭電力變壓器絕緣狀態評估指標體繫，提齣絕緣度的概唸併劃分瞭絕緣狀態等級，根據區間層次分析法確定電力變壓器絕緣狀態評估指標的區間數權重，建立瞭基于區間層次分析法的電力變壓器絕緣狀態評估模型，結閤區間數理論實現對電力變壓器絕緣狀態的評估。實例分析的結果錶明，所建立的電力變壓器絕緣狀態評估模型是閤理有效的。

For the assessment uncertainty of power transformer insulation condition,a new assessment method of power transformer insulation condition based on interval?based analytic hierarchy process (IAHP) is proposed. The assessment index system of the power transformer insulation condition was established. The insulativity concept is presented,and the grades of in?sulation condition are divided. According to IAHP the interval number weight of the assessment index was determined,and the assessment model of the power transformer insulation condition was established. The assessment of power transformer insulation condition is realized in combination with the interval number theory. The instance analysis results show that the established as?sessment model of power transformer insulation condition is reasonable and effective.
