Plasma burning device for electrothermal and electrothermal/chemical gun systems

摘要

A plasma burning device for an electrothermal/chemical gun system includes a case hating a bottom and an interior; plasma material accommodated in the interior; and a high-voltage electrode passing through the case bottom into the case interior. The high-voltage electrode is adapted to cooperate with a gun tube acting as a counter electrode for generating an arc to combust the plasma material. The high-voltage electrode includes a conductor bar adapted to be coupled to a high-voltage source; an insulation surrounding the conductor bar; a conductor sleeve electrically connected to an end of the conductor bar and extending towards the case bottom along a length portion of the conductor bar. The conductor sleeve surrounds the insulation and the conductor bar and has a non-insulated outer surface. Further, an insulating cap is provided which covers the end of the conductor bar.
