Dianci bileiqi电容式套管的电容芯子设计方法主要有“等电容”、“等厚度”、“等裕度”、“不等电容、分段等厚度”、“大小极板”5种方法，5种方法均是要求轴向场强尽量均匀，也即是尽量保持轴向场强相等。文中通过理论计算，分析电容屏极板台阶长度与局放起始电压的内在关系，提出了一种新的电容芯子轴向场强的设计方法。首先提出“等厚度、不等轴向场强”设计方法，说明了通过对轴向场强的控制能够实现套管的每层绝缘裕度相等，为满足轴向场强在许用场强以下，提出了“等厚度、部分不等轴向场强”设计方法，该方法优化了“等厚度、不等轴向场强 ...

, 1979 电磁离心分离装置利用外加电磁场驱动混合气体,产生有利于分离效应的高速旋转流场。这种原理可应用于气态核反应堆、气态核火箭的燃料约束,以及同位素(特别是重同位素)的分离。过去的分析都限于二元轴对称流动,流动进出口的条件未很好处理。本文分析三元流场,用小磁雷诺数展开得到了渐近解,求出了零阶量的分布。本文计算了分离系数 ...

Gaoya dianqi高功率Tesla变压器在脉冲功率技术领域应用广泛，但其次级线圈处于非均匀电场中，线圈匝间电压分布不均，容易导致匝间绝缘击穿。文中设计了一台双磁心Tesla变压器，利用有限元法建立次级线圈的电场仿真模型，分析其匝间的电场分布情况。针对匝间电压分布不均问题，提出次级线圈首尾两端双线并绕及增加屏蔽环来改善电场分布的措施，使最大场强小于微小油间隙的击穿场强，确保变压器次级线圈的绝缘安全。通过仿真分析发现首尾两端并绕可改善电场分布，但并绕匝数不宜过多。高压端增加屏蔽环后，场强分布更加均匀，最大场强下降62.9 ...
