Gas discharge switch - comprising two main electrodes in switching chamber, cathode having opening for igniting discharge

摘要

Gas discharge switch comprises at least two main electrodes, arranged at a distance d from each other, for low pressure gas discharge and assembled in a switching chamber, and a cathode and anode form a discharge path for the low pressure gas discharge ignited by raising the electron density in the cathode rebound chamber. The cathode has an opening for igniting the discharge. The novelty is that the openings (4,5) each have separate inserts (21) made of a material of higher electrical resistance than that of the electrode material. USE - Switches high currents and voltages with high pulse repeating frequency.
