| 摘 要： | 对应用在Tesla型强流加速器中的电子束二极管绝缘子进行了仿真,发现电场增强区域与实际发生击穿区域基本一致。从绝缘子沿面电场分布、电力线和绝缘子表面所成角度分布以及材料缺陷等方面分析了击穿发生的原因。认为材料中存在缺陷是导致绝缘子发生击穿的主要原因,局部场增强和非最优化结构设计促成了击穿的发生。对影响绝缘子沿面电场分布的同轴线关键位置进行了设计,得出了阳极倒角半径和阴极屏蔽环半径两个参量的最佳取值范围。

| Abstract: | The diode insulator applied in the Tesla-type pulsed power generator has been simulated.It is found that the field-enhancement regions are generally the breakdown regions.The reasons responsible for breakdown are explored from the aspects of electric-field distribution,angle distribution of electrical lines relative to insulator surfaces,and the imperfections in the insulator,etc.It is believed that the imperfections are the main factor responsible for breakdown,and the local field enhancement and improper ... |
