Surface flashover across the insulators in vacuum is the major limitation of the performance of the high power system, such as high power microwave tube, pulse power switch, high - energy linear accelerator, etc. flashover studies are of considerable importance in many applications. alumina ceramics are used widely in vacuum insulation system. the flashover and charging performance have been systematically investigated on alumina ceramics in vacuum under pulse voltage ( 0. 7 / 4 ^ 8 )
真空中絕緣子沿面閃絡現象是制約高功率微波管、脈沖功率開關、高能粒子加速器等系統性能的主要原因,這是因為真空中絕緣子在一個比自身及相同真空間隙擊穿電場低得多的電場下就發生了表面閃絡的緣故,研究真空中絕緣子沿面閃絡現象及其形成機理對于改善和提高系統性能有重要意義。A corporation is a listed corporation which deals in broadcasting and communication transmitting tube, vacuum interrupter, and the likes of electro - vacuum device. copper is one of the most important materials which a corporation uses
