Gaoya dianqi为提升干式空心电抗器支撑体系的稳定性，保证支柱绝缘子尽可能多地承受抗压载荷、减少受弯载荷，文中提出了一种基于力矩平衡原理的支柱绝缘子安装节径设计方法。首先将主体线圈沿中轴线进行对半切割，以对半切割后的主体线圈为研究对象，将线圈各包封铺平展开，然后利用力矩平衡原理计算安装节径值。通过比较三维建模软件质心特性与力矩平衡原理计算节径值的差异，分析了气道撑条结构对安装节径值的影响。以某型号特高压干式空心电抗器为例，采用有限元仿真计算方法，分别计算了自重作用与地震作用下支柱绝缘子的弯矩，验证该理论预测方法的有效性。

基于RBF神经网络和有限元技术的高压支柱绝缘子机电模拟及均压结构优化研究
Dianci bileiqi, 2019 高压支柱绝缘子在电力系统中应用广泛,支柱绝缘子电气、机械性能与电力系统运行稳定性关系密切,本文基于有限元技术对高压支柱绝缘子机电性能进行精细化建模分析。计算结果表明:支柱绝缘子电气方面最大电场强度位于高压侧均压环表面,且机械方面第一主应力最大值150MPa主要集中在法兰支撑片位置。进一步提出PSO-RBF混合算法对支柱绝缘子均压结构参数进行优化设计,运行结果表明:PSO-RBF神经网络对原始有限元计算数据点非线性拟合映射效果良好,在原本数据点基础上进行了高精度延拓,且算法具有较好收敛性 ...
