| 摘要: |
| GIS运行状态评估是指导GIS状态检修的重要手段。将可拓分析理论引入GIS状态评估中，以SF6气体组分指标为主，并结合SF6气体的纯度、湿度和气体中空气含量指标来构建关联函数。结合关联函数值与规程中规定的注意值和警示值的关系确定GIS状态等级关系及相应的检修策略。运用熵值法理论解决了GIS状态评估中各指标的权重问题。实例分析表明，该评估方法可以准确地评估GIS的各个气室状态，有利于监测预警和制定综合检修策略。 |

| Abstract: |
| Condition evaluation of GIS is an important approach to providing decision-making for condition maintenance. Extension analysis is introduced into condition evaluation of GIS. With the basis of indexes of SF6 gas components, combining with the purity, air humidity and air content of SF6 indexes to construct correlation functions according to SF6 gas components are widely used to the operation of GIS. Determine the relationship between the condition level and the corresponding maintenance strategies based on relations of correlation function values and note values and warning values specified by procedures. Entropy method is used to solve the weight problems of each index for GIS condition assessment. The results of an example analysis indicate that the method in this paper is capable of assessing the state of GIS in each chamber and it is conducive to the monitoring and early warning and developing comprehensive maintenance strategy. |
