Research of chaotic characteristics of low-voltage air arc
In order to explore the principle of low-voltage air arc, to find out ways of arc control, and use experimental platform of 220 V air arc generator, the resistive, inductive and resistive loads are taken as the research objects. The research combined with experiments and computer simulation analysis, based on the chaotic phase space reconstruction theory, the C-C method, the Wolf algorithms and the Cao method, the dynamic chaotic behaviour of the low-voltage air arc current is identified quantitatively. Through the processing of the experimental and emulational data, the chaotic phase diagrams which describe chaotic attractors clearly are drawn. The LEmax of low-voltage air arc current are obtained, and the essential characteristic that the chaotic behaviour exists in low-voltage air arc is revealed and described.
