ELECTRIC-ARC PLASMATRON FOR TREATMENT OF FLAT SURFACES OF PARTS Russian patent published in 2020 - IPC H05H1/26 

FIELD: electrical engineering.

SUBSTANCE: invention relates to electrothermal equipment, namely to devices producing plasma. Electric arc plasmatron comprises horizontally tubular housing made of nonconducting current of refractory material, inner cavity of which forms longitudinal slit chamber, in the tubular body perpendicular to the slit chamber axis there are two opposed holes, in one of which an anode electrode is installed, and in the other – cathode electrode, which are connected to power supply unit with level and constant sign by voltage, as well as to arc ignition unit. One end of the tubular case is connected to the working plasma-forming gas supply unit. Tubular magnet core movable with reciprocation drive is installed coaxially with tubular housing, which inner diameter is larger than outer diameter of tubular housing, in cavity of tubular magnetic conductor between its inner surface and outer surface of housing there are two poles with windings connected to another source of controlled DC voltage, wherein pole axis is located perpendicular to electrode position axis, pipeline for cooling electrode passage is made in the form of channels in wall of tubular housing, tubular housing is fixed on moving platform, having reciprocating drives up-down, right-left.

EFFECT: simplification of design, control of speed of movement, temperature and volume of plasma at outlet of tubular housing.
