GIS屏蔽罩松动状态特性仿真及试验分析

Gaoya dianqi
机械类缺陷是GIS设备运行阶段的常见缺陷之一。针对机械缺陷导致GIS异常振动问题开展机理研究，能够有效排查现场设备故障隐患。文中首先通过有限元建模，对某126 kV三相共体式GIS运行时可能出现的屏蔽罩松动缺陷进行仿真，探究设备在缺陷状态下的异常振动机理及特征。其次，分别对建立的GIS正常模型和屏蔽罩松动模型进行磁固耦合仿真，通过后处理获得了筒体上的振动结果。最后，搭建了同一型号的GIS试验平台进行了缺陷模拟试验，对相同缺陷状态下GIS运行振动信号进行了检测分析。结果表明，文中所分析的126 kV ...

基于振动信号的油浸式铁心电抗器典型缺陷诊断方法研究

Gaoya dianqi
油浸式铁心电抗器正常运行期间其振动由绕组受力、铁心磁致伸缩效应以及铁心饼间的麦克斯韦力导致。通过构建电抗器磁—固耦合三维模型，对电抗器在3种载荷作用下的轴向及径向振动响应分布进行分析。在此基础上搭建电抗器振动试验平台获取了电抗器箱体振动信号，通过调整铁心轴向压紧力，对箱体振动信号进行采集，通过提取各机械状态下的振动频谱特征可知，随着电抗器铁心轴向压紧力降低，箱体振动信号频谱发生变化，采用3种贝叶斯优化的网络分类器模型，对不同压紧力下的机械状态进行识别，准确率分别达到了94.5%、94.2%与95.0 ...
