摘　　要：通过仿真技术研究了空气开关电器中空气电弧。建立了电弧磁流体动力学(MHD)模型,并求解模型控制方程,分析了电弧运动、触头打开、电弧转移等过程。该项研究可为开关电器产品的优化设计提供理论参考。The electric arc in air switch was researched by simulation technique. The arc model based on mag- netohydrodynamic theory was built and the model control equation was solved, then the courses of arc motion, con- tact breaking and arc transfer were analyzed. This research ean provide theory reference for optimization design of switch apparatus product.
