Механизм Инициирования Процесса Коммутации Короткого Вакуумного Промежутка Вспомогательным Искровым Разрядом

Abstract

The results and analysis of experiments are presented, the purpose of which is to study the mechanism of ignition of a high-voltage arc discharge in a vacuum gap. The results indicate that the development of an arc discharge under the presented conditions is occurs mainly due to the ionization of the residual gas by a flow of overheated electrons with an energy of 100−500 eV from an auxiliary spark discharge.
