摘要

真空中沿面闪络现象是制约真空设备耐压强度的一个重要因素

采用多层高梯度绝缘技术

比传统绝缘结构能显著提高击穿场强。介绍了该技术的研究现状

并从真空沿面闪络的二次电子崩理论入手

分析该结构对闪络过程的影响。同时

从小间隙串联的模型以及对外加电场的影响两方面

解释了多层高梯度绝缘结构可以提高绝缘性能的原因

它与公开的实验现象和结论也比较符合。

Abstract

The electrical strength of vacuum insulation system is usually limited by the flashover phenomenon across the surface of insulator in vacuum.Multilayer high gradient insulator technology

a new insulator structure

is reported to perform higher breakdown electric field strength than conventional insulators.An investigation of this technology is presented

and an analysis from SEEA is explained.On the other hand

a model of small gap series and a simulation analysis are provided to account for the performance of improving insulator surface dielectric strength.
