Abstract
The invention discloses an anode of a supersonic plasma torch, and the supersonic plasma torch. Mainly, the conventional laval-type anode is divided into two parts, wherein one part near a cathode body is called as a basic anode; the other part far away from the cathode body is called an auxiliary anode; and the two parts are isolated by a high-temperature-resistant insulation ceramic chip. The cathode body is fixed on a conductive torch core and is sequentially connected with the basic anode and the auxiliary anode in an axial direction. When the anode works, an arc root is transferred from the basic anode to the auxiliary anode, so that a nozzle of the laval-type basic anode with a complicated structure is protected while an electric arc is lengthened. Therefore, the voltage is increased under the condition that the working current is unchanged. As a result, the energy utilization rate is improved.
