Plasmatron

摘要

A plasmatron comprises a casing wherein a water-cooled cylindrical hollow electrode is placed so that its bottom faces the power lead-in and the butt contacts an annular insulating vortex generator which contacts a water-cooled nozzle. The casing also houses a lead-in coil enveloping the cylindrical hollow electrode and positioned with a certain clearance between the electrode and the lead-in coil. One end of the coil is connected to the power lead-in and the other to the butt of the cylindrical hollow electrode.
