摘要
在真空断路器开断交流电流真空间隙介质恢复物理过程的基础上,建立了灭弧室介质强度恢复的数学模型.采用Saber软件的MAST语言编程,以真空断路器开断空载变压器的一个完整过程为例进行了仿真计算.根据计算结果,分析了暂态过程、过电压的特点以及变压器、真空断路器参数对过电压的影响.
Chamber medium strength math model is established in this paper, according to vacuum circuit breaker interrupting characteristics based on the physic process of interrupter with ac current. Taking the interruper with no load transformer as an example, vacuum circuit breaker is simulated with MAST language of Saber software. Then , transient process,overvoltage charactersitics and transformer, vacuum circuit breaker parameter are analyzed.
