GENERATING ELECTRIC ARC, WHICH DIRECTLY AREALLY THERMALLY AND MECHANICALLY ACTS ON MATERIAL, AND DEVICE FOR GENERATING ELECTRIC ARC

摘要

Generating electric arc, which thermally and mechanically acts on material in such manner that the electrical arc is shaped and guided by the action of magnetic field and hydro-mechanical forces on the electrical arc, wherein: —the substantial part of the electric arc acts directly and areally on conductive and/or non-conductive material to be disrupted, —the substantial part of the electric arc's heat flow is directed into the material to be disrupted, —wherein both electric arc roots move on the electrodes of the generator and the electric arc has preferably a shape of a spiral. A device for generating an electric arc with thermal and mechanic action on material containing axially symmetrical electrodes, i.e. an anode (4) and a cathode (6), a spark gap (7), nozzles (5) for the working medium flow, cooling media inlet and outlet (12), electric power supply (14), ring-shaped magnets (9) whose section has the shape of a triangle and the anode (4) has the shape of the diffuser with an angular span from 5 0 to 130°.

1. Generating electric arc with thermal and mechanic action on material, being formed between electrodes in a spark gap characterized in that the electrical arc is shaped and guided by the action of magnetic field, composed of external magnetic field and of electric field of the arc itself, and hydro-mechanical forces, which are created by the interaction of smoothly expanding working medium with the electric arc, on the electrical arc generated between the electrodes forming an axially symmetrical electrode assembly, in such manner that:
the substantial part of the electric arc acts directly and areally on conductive and/or non-conductive material to be disrupted, the substantial part of the electric arc's heat flow is directed into the material to be disrupted, at least part of the electric arc is formed into the shape of a spiral,wherein both electric arc roots are moved on the electrodes of the generating device.
