Study of recovery phenomena in a high-current pulse-triggered vacuum switch

The recovery capacities of a triggered vacuum switch after the crossing of a 25- mu s high-current pulse were investigated. The recovery time is less than 100 mu s. An experiment was conducted with several electrodes with different gaps, and the influence of an axial magnetic field on the switch was studied. A diffuse arc mode was achieved, making possible a commutation power as high as 10/sup 9/ VA.<
