Abstract
A plasma burner has contact protection means for protecting the operator against impermissibly high voltage and the burner head itself against destruction. The burner comprises a nozzle 1 attached to a nozzle holder 2 and surrounded by a nozzle cap 3, with cooling water flowing between the nozzle 1 and cap 3. Disposed over the nozzle cap 3 and insulated therefrom by an air gap 9 is an electrically conductive protective cap 8 which is mounted on the burner shaft by means of two contact pieces 7 constructed as half rings. Each of the two contact pieces 7 is connected via a cable to a fault current protective circuit. The operating conditions are monitored by means of voltage indicators which effect switching functions, and resistors, capacitors and diodes connected in correspondence thereto, and if malfunctions occur, switching operations are triggered which protect the plasma burner and the installation. <IMAGE>
