摘　　要：运用三维有限元分析的方法,以MCCB瞬时脱扣器为研究对象,采用ANSYS分析软件计算衔铁运动的静特性,接着以静态特性的分析为基础,利用多体动力学仿真软件ADAMS对断路器进行建模并对其动态特性进行仿真分析,计算脱扣器最小脱扣电流和不同短路电流下的脱扣时间。Based on the 3D finite element method, taking MCCB＇ s releaser as example, the static characteristics of the magnet releaser was obtained via ANSYS. Then based on the analysis of the static characteristics, the MCCB＇ s model was built and the dynamic characteristics were simulated by using ADAMS. The minimum tripping current and the tripping time under different short-circuit current were calculated.
