金属氧化物避雷器结构参数对雷电防护影响的有限元分析

open access: yesDianci bileiqi, 2018
为了有效利用金属氧化物避雷器(metal oxide surge arrester,简称MOA)进行线路雷电防护,需要准确分析避雷器结构参数对雷击能量与电场的影响。本文利用COMSOL软件建立110kV MOA模型,介绍其材料参数设置及求解方法,对MOA模型进行仿真冲击,并与试验数据进行对比。最后分析避雷器电阻芯直径和高度、绝缘层介电常数和厚度对避雷器吸收能量和电场强度的影响。分析结果表明:COMSOL中建立的MOA模型仿真数据与试验结果较为一致,能较好反映其在雷电流冲击下的响应特性。电阻芯直径越大 ...

基于自适应神经模糊推理系统的避雷器有效运行寿命估计方法

open access: yesGaoya dianqi
估算金属氧化物避雷器的使用寿命一直是一项挑战,它决定着输电系统的安全稳定运行。基于此,文中提出了一种基于自适应神经模糊推理系统(adaptive neuro-fuzzy inference system,ANFIS)和支持向量机回归(support vector machine for regression,SVR)组成的组合时间序列预测模型,用于估算金属氧化物避雷器(metal oxide surge arrester,MOSA)的使用寿命。首先,文中进行了现场测量 ...
