摘要
电器开关电弧的燃弧时间非常短,为了观察和分析燃弧的整个过程,提出一种基于电弧图像的可视化仿真方法。电弧弧柱的特征点从电弧图像中被提取出来,基于磁收缩效应、非均匀B样条理论和电弧特征点,建立一种弧柱的可视化模型。仿真结果显示,提出的可视化仿真方法对于低压电器开关电弧是有效的。
Research on switching arc motion for the improvement of low voltage electrical 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 was presented. The feature points of arc column were extracted from arc image. Arc column visual model was constructed based on magne- tic 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 electrical apparatus.
