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。

基于超声导波的盆式绝缘子缺陷检测衰减率变化规律研究

Dianci bileiqi
盆式绝缘子是GIS设备的关键设备，盆式绝缘子的健康状况对GIS以及电网安全运行具有重要影响。文章对超声导波检测盆式绝缘子缺陷进行有限元仿真，并搭建基于超声导波的盆式绝缘子缺陷检测平台，对不同偏移角度的裂纹缺陷和不同排列方向、数量的孔洞缺陷进行检测，来探究在不同角度缺陷和不同数量缺陷下，超声导波检测盆式绝缘子缺陷时的衰减率变化规律，发现裂纹偏移角度（较水平方向）越大，导波幅值衰减率越大，孔洞数量越多，导波信号幅值衰减率逐渐增大，并且，纵向排列的孔洞信号幅值衰减率要比横向排列方向要快。
