摘要
建立了三维的低压断路器开断过程中,空气电弧运动及栅片切割数学模型,通过仿真研究栅片的切割过程并模拟了电弧的运动,获得了烧蚀情况下的电弧电压曲线;同时,经过切割过程相应的试验研究,利用简化装置观察了电弧的动态影像。
A three-dimensional mathematical model of air arc movement and gate slice cutting was built.Arc voltage curve under the condition of ablation was obtained by simulating the process of splitter plates cutting and the arc movement.At the same time,the experiment of the cutting process was performed.Arc dynamic image was observed by the simplified device.
