摘要
Experimental investigations of the dynamic behaviour of a nitrogen arc in DC and AC plasma torch has been performed. We have observed that the dynamic behaviour due to the displacement of the anodic root of the AC arc is similar to that of the DC arc but occurs only for the half-wave of the alternating voltage for which the movement of anodic root is possible. The influence of pressure on the dynamic behaviour of the DC arc was studied and discussed. We have experimentally verified that the frequency of voltage fluctuations depended on the pressure by a power law with the adiabatic coefficient. The influence of different supply circuits on the fluctuations of the electric parameters of the arc was described.
