| 摘 要： | 本文在假定电弧截面温度分布的基础上,通过对电弧内部能量平衡的研究,提出了一个横向磁场中动态电弧的近似计算模型。本文简略介绍了这一近似计算模型的推导过程和参数选择,并对横向磁场中的0.1MPa空气里的电弧进行了数值计算,计算的结果与实验结果较为接近。

Approximate Calculation of Dynamic Arcs in Transverse Magnetic Field |
| |
| Abstract: | Based on the assuming of the arc temperature distribution and the investigation of the energy balance in the arc,a simplified model of the dynamic arc in transverse magnetic field is proposed.The derivation process and the parameter selection of the simplified model have been described in this paper.The numerical calculation of arcs in transverse magnetic fields in air at atmospheric pressure has been made.The results of the calculation are approximately similar to that of the experiments. |
