Visual simulation of low voltage apparatus switching arc
Jiaomin Liu, Xinfu Li · 2005
Research on switching arc motion for the improvement of low voltage apparatus is important. But arcing time is very short in the operation of switchgear under the real situation. In order to observe and analyze the whole process of arcing, a kind of visual simulation method based on arc image is presented. The feature points of arc column are extracted from arc image. Arc column visual model is constructed based on magnetic pinch effect, no-uniform rational B-spline technique and the arc feature points. Simulation results show that the proposed approach is an effective visual method for switching arc of low voltage apparatus.
