Abstract

Abstract

This paper presents the design of a repetitive frequency gas spark switch. The switch adopts a three-electrode field-distortion structure, which has the advantages of small size and compactness, and it can work at voltage 100 kV, current 10 kA. Experimental study of the trigger characteristics of this field distortion spark gap switch were carried out with the changes in frequency, gas composition, working pressure and work coefficient. The breakdown time delay and jitter of the switch are calculated, and the main factors influencing the breakdown characteristics of the switch are analyzed. The experimental results show that the time jitter of the switch increases with the repetitive frequency. The switch has better performance when filled with gas mixture of SF₆ and N₂ of volumetric ratio of 1 ∶1, the working coefficient mainly affects the time jitter of the second discharge spark gap (gap 2).
