基于Savitzky-Golay滤波器的有载分接开关振动信号包络线提取方法研究

Gaoya dianqi
分接开关切换过程中各触头依次分合碰撞产生振动信号，信号特征反映了碰撞能量和触头刚度。为进一步研究触头碰撞动力学特性，文中首先建立M型分接开关四触头的碰撞动力学模型，计算了静触头刚度对模型响应特性的影响规律；其次模拟了静触头弹簧松弛故障，获得了弹簧0.6 mm线径和1.0 mm线径对应的振动信号；然后提出基于Savitzky-Golay滤波器的包络线计算方法，提取奇—偶切换和偶—奇切换时振动信号的平均包络线；最后计算了2种线径静弹簧对应的平均包络线的相关系数 ...

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 ...
