特高压换流变压器阀侧套管缩比模型典型缺陷下电场分布特性仿真研究

Gaoya dianqi
换流变压器阀侧套管内部混入金属颗粒、电容芯体产生裂纹是目前常见的故障，研究套管在不同电压下的电场分布规律以及缺陷对电场分布的影响对于套管的优化设计及故障分析具有重要意义。文中以±800 kV特高压换流变压器套管为原型，建立了±72.5 kV环氧浸纸电容式套管仿真模型，计算套管在交直流电压下的电位分布和电场分布，并研究了两种缺陷对于套管电场的影响。结果表明套管含金属颗粒或裂纹缺陷时，对于电场的畸变影响较大。研究结果为后续缩比套管模型不同缺陷局部放电试验的分析提供了基础 ...

基于迭代计算的介电功能梯度绝缘子电场优化研究

Dianci bileiqi
介电功能梯度绝缘子可以在不改变几何结构基础上，优化整体电场分布，提高沿面闪络电压。依据经典电磁场理论，得到梯度绝缘子电场分布特性及优化理论。针对盆式绝缘子，以降低沿面最大场强为优化目标，提出一种基于迭代计算的盆式绝缘子电场优化设计方案。结合电场优化理论及迭代算法流程，通过分析叠层数、介电常数上限及表层厚度等影响因素，对设计方案的电场优化效果进行对比研究。计算结果表明，对比匀质盆式绝缘子，体/表层梯度盆式绝缘子沿面最大场强降幅明显，最高可达34.37%、39.08%，优化效果显著，电场分布均匀性大大提升。
