摘要 建立了金属氧化物避雷器(MOA)内部微正压有限元三维仿真模型,采用热流固耦合对其防爆板结构进行优化设计,研究温差、气压与防爆板应力分布的数据关联关系;采用金属应变片采集内部气压变化时防爆板形变数据,运用K-means聚类提取防爆板形变特征进行数据分类,从而实现异常检测与特征分析,达到在线监测及故障诊断目的。 In this paper,a three-dimensional finite element simulation model of micro positive pressure in MOA is established,and the optimized design of its explosion-proof plate structure is carried out by the method of thermal-fluid-solid coupling.The data association between temperature difference,air pressure and stress distribution of explosion-proof plate is studied.After using metal strain gauge to collect the deformation data of theexplosion-proof plate when the internal pressure of MOA changes,K-means clusteringis used to extract the deformation characteristics of theexplosion-proof plate for data classification,so as to realize anomaly detection and feature analysis and achieve the purpose of online monitoring and fault diagnosis.
