Study of the New Generation of Thyratrons with Average Switching Power up to 0.5 MW: Experience of Application in Electrophysical Equipment

摘要

An analysis of competitiveness of thyratrons in relation to up-to-date solid-state devices has been carried out. The design features and parameters of a number of new TGI thyratrons with a hot combined impregnated cathode for operating voltages of 30, 50, and 75 kV, average switching power from 150 to 500 kW and pulsed power to 250 MW, are presented. Thyratrons have a tetrode design with air cooling in the metal ceramic version. The main field of application is high-power electrophysical equipment. In particular, we present the examples of using thyratrons in accelerators as modulators, as well as pulse corona power supplies for air purification systems from hydrogen sulfide, ammonia, and other harmful gases in the streamer corona discharge.
