摘要
Predictions of the temperatures of the anode of free burning arcs are made using a theory that treats an are and its electrodes as a unified system. The theory predicts the temperature distributions of the are column, the cathode and the anode as a function of the are operating conditions. Temperature profiles on the surface of copper anodes for arcs in argon are calculated for various are operating conditions. Theoretical predictions of the threshold current for melting a water-cooled copper anode range from 1260 to 480 A for anode thicknesses ranging from 2 to 10 mm and are in good agreement with experimental results.
