基于振动超声复合信号的变压器套管及升高座故障监测方法

Dianci bileiqi
套管是变压器的关键部件之一，保障套管的安全正常工作对变压器乃至整个供电系统的稳定运行都有重要意义。近年来，随着在线监测技术的不断发展成熟，基于振动分析法和超声法的状态监测技术在不同电力设备上都得到了广泛运用，但在变压器套管上的应用还有待进一步研究。套管的常见故障可分为放电性故障、机械故障、过热性故障及油位异常几类，本文提出了通过监测套管上的振动超声复合信号对变压器套管的机械故障与局部放电故障的监测，给出了基于振动超声复合信号传感器的故障检测装置及信号处理电路。振动超声复合信号包括较低频率的振动信号 ...

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 ...
