摘　　要：结合目前国内外高压断路器的状态监测及评估现状,将模糊数学理论应用到高压断路器的状态评估中。采用模糊层次分析法代替层次分析法对评价因素集进行权重分配,改进了以往模糊综合评估中的判断矩阵一致性问题,确定了各评判因素对象及其计算方法和隶属函数,建立了模糊综合评估模型,利用多种评价因素对高压断路器的工作状态进行了评估。Based on the status monitoring and evaluating of high voltage circuit breaker in domestic and international, fuzzy theory was applied in assessing condition of the HVCB. Firstly, the fuzzy analytical hierarchy was adopted instead of analytical hierarchy which made the judgment more consistent. Then, the paper discussed the main factors of HVCB＇s condition and evaluated the importance of them. Finally, the multi-layer fuzzy comprehensive evaluation model for HVCB was presented, and an example was analyzed.
