摘要
研究了低压开关电器稳态电弧特性仿真。在磁流体动力学基础上,针对低压断路器简化灭弧室建立了稳态空气电弧等离子体模型,并引入了P1辐射模型进行仿真分析,分析了低压稳态空气电弧等离子体内各项参数的分布。该成果为电弧等离子体动态特性研究提供了帮助。
The simulation of low-voltage steady-state arc characteristic of air switch was studied.Based on the magnetohy drodynamic theory,a three dimensional air arc model in a simplified low-voltage quenching chamber was set up,and P1 radiation model to implement the simulation of electric arc plasma was introduced.The distribution of steady-state arc parameters was analyzed.It can help study of arc plasma dynamic characteristic.
