Abstract: The results and analysis of experiments are presented, the purpose of which is to search and study the possibilities of reducing the erosion of the triggered vacuum switch ignition system. The results indicate that the introduction of a compact limiting resistance into the ignition system of the triggered vacuum switch, which separates the cathode into two galvanically connected parts, makes it possible to spatially separate the area of operation of a high-current arc discharge from the ignition system. Thus, it is possible to significantly weaken the destructive effect of the arc discharge on the ignition system.

Keywords: vacuum arc, spark discharge, switcher, erosion.
