摘要

本文讨论了在真空电器件实际条件下自由大粒子的产生方式和粒子与电极相互作用时发生的物理过程。本文提出了真空击穿起始模型,包括松散结合粒子在电场作用下的释放、它们向相反电极的加速、对电极的冲击以及潜在电子发射中心的形成。一些已发表的观测和数据表明,在长时间延迟(几十微秒)的厘米间隙中击穿,间接表明在击穿之前立即存在短期的发射中心,因此它们支持该模型。讨论了电场作用下冲击区材料塑性变形形成发射中心的机理。击穿起始的最后阶段涉及发射电流与阳极的相互作用,导致阳极热不稳定

Clump Hypothesis and Mechanisms of Breakdown Initiation in Centimeter Vacuum Gaps
This paper discusses ways of free macroparticle generation in real conditions of vacuum electric devices and physical processes occurring at the particle interaction with an electrode. As a result, a model of vacuum breakdown initiation was suggested, including release of loosely bonded particles by electric field, their acceleration to an opposite electrode, impacts onto the electrode and formation of potentially electron emitting centers. Some published observations and data on breakdowns in centimeter gaps with long delays (tens of microseconds) indirectly indicate short-term existence of emission centers immediately prior breakdown, and thus they support the model. Mechanism of the emission center formation by plastic deformation of material in the impact zone in presence of electric field is discussed. A final stage of breakdown initiation involves emission current interaction with the anode, leading to the anode thermal instability
