METHOD FOR FORMING OF ARC DISCHARDE IN A PLASMATRON

摘要

The invention relates to electronics, in particular to method for forming and stabilization of arc discharge in an indirect action plasmatron. A method for formation of arc discharge in the plasmatron consists in following: optimal quantity of neutrods depending on no-load voltage. Length of a first neutrode is set in the limits of a laminar arc section. Length of the next neutrode is taken 1,3-2,2 times more than length of the previous neutrode. According a preset threshold level, ratio of no-load voltage and radius of neutrodes it is determined radii of neutrodes for acceptable no-load voltage. The technical result is provision of necessary monitoring of plasmatron operation in a metal melt of a melting furnace at increased working pressure in a reaction zone.
