Abstract

Abstract

When a MV triggered gas switch (TGS) is triggered by an electric pulse, a good electrical connection between the trigger generator and the TGS is required to ensure the trigger effect. Besides, a protective method is also necessary to avoid the damage to the trigger generator which feeds back from the MV main pulse after the TGS is closed. In this paper, a novel trigger pulse feed and protection method is introduced. The trigger pulse is introduced via a protective resistor, which is mounted between the inner and outer cylindrical electrodes of the pulse transmission line. The MV pulse is attenuated because the voltage is resistively divided by the resistor and trigger cable arrangement. Both the complex breakdown processes of the switch and its insulation issues are experimentally studied. The function and the beneficial effects of the protective resistor, installed together with an additional inductor, are discussed. Finally, the structure and parameters of these two protective components are set to 500 Ω and 2 μH, in which conditions the switch is demonstrated to successfully work at 2.6 MV.
