Abstract :
A triggered vacuum switch (TVS) is an important component in pulsed power systems due to its quick switch, rapid dielectric recovery, small volume, convenient trigger system, simple structure, etc. A sample of field-breakdown TVS is fabricated, and its turning-on process is described in this paper. The initial plasmas play an important role in the process of TVS operation; its development includes two parts: (1) generation and (2) expansion. Based on the field breakdown principle, an electron emission model is chosen to describe the generation of initial plasmas. A heat conduction model is set up to deduce the expansion of initial plasmas. The model calculated result is accordant with the delay experiment.
