摘要
在建立的喷口电弧二维磁流体动力学数学模型的基础上,开发了SF_6断路器的CAD软件。通过灭弧室与操动机构的联合模拟计算,详尽分析了电弧能量扩散的过程与规律,为膨胀式断路器的开发与研究提供了理论依据。
Based on two dimensional MHD mathematical model of nozzle arc, a CAD program is developed for SF6 circuit breaker design. Through the analog calculation of arc extinguish chamber and mechanism, the process and the regularity of are energy expansion are analyzed. The result can be refered in the design of thermal expansion circuit breaker.
