Formation of asperities on electrode surfaces of high-voltage vacuum insulation systems by striking microparticles

Abstract

The authors analyzed the ability to produce asperities on the surface of discharge electrodes vacuum insulation systems by hitting the electrode surface small clumps of material − microparticles. Insulation systems with electrodes made of copper, aluminum and titanium were analyzed. The dependence on the distance between the electrodes and the minimum voltage value at the terminals of the insulation system was determined, under the influence of which accelerated spherical microparticles with different radii cause deformations of the electrode surface.
