【摘要】 以塑壳式断路器用电磁铁为研究对象 ,在磁场计算的基础上 ,推导出更精确的气隙磁导和漏磁导公式。新的等效磁路计算的电磁铁特性 ,经实验验证具有很高的精度。本文建立的电磁铁等效磁路除了保持传统磁路方法的优点外 ,还能达到很高的计算精度
【Abstract】 In this paper, based on experiment verification, more precise formulae, air gap magnetic conductance and leakage magnetic conductance, can be obtained using the results of magnetic field. Based on these two formulae, not only can the established equivalent magnetic circuit maintain the advantage of the original circuit method, but also improve the calculating precision.
