Design of high-voltage hold-off radial insulator stack with grading rings

摘要: 以形成线储能结合脉冲压缩方式产生数 MV高压输出,是脉冲功率系统中常见的技术途径,其中绝缘堆是该类装置工程成败的关键。分析了几种径向均压绝缘堆的均压机制,基于静电场分析程序对径向均压绝缘堆结构进行了优化设计,给出了径向电阻的设计方法。研究表明：采用均压环且均压环与径向电阻电气接触的绝缘堆结构可以获得较均匀的径向电场分布,而径向电阻是绝缘堆设计的关键。在有效作用时间100 ns的4.5 MV加载电压下,优化设计的绝缘堆阴极三相点电场控制在25 kV/cm,Martin电场约120 kV/cm,低于理论击穿值。
