DEVICE FOR INITIATING DISCHARGE IN HIGH-FREQUENCY INDUCTANCE PLASMATRON Russian patent published in 1998 - IPC

FIELD: plasma engineering; plasmatrons used for heating gases. SUBSTANCE: device has high-melting metal electrodes and inductance turn secured in insulator. Turn ends are connected to electrodes arranged along longitudinal center line of turn. Inductance turn is made of material affording elastic strain. Device may incorporate annular nonretentive core placed inside inductance turn. EFFECT: improved reliability, reduced power and plasma-forming gas requirement due to reduced discharge-initiating time and dispensing with external power supply, facilitated discharge initiation procedure. 2 cl, 2 dwg
