【摘要】 借助三维矢量场分析软件包VECTORFIELDS对瞬时脱扣器建立了三维有限元模型 ,并对其磁场分布及静态吸力特性进行了计算 ,同时也采用了磁路的方法计算了静态特性并将计算结果同前者进行了比较。还对短路电流到来后 ,瞬时脱扣器的动态特性进行了计算和分析更多还原

【Abstract】 The attractive behaviors of instantaneous release are calculated by two methods:magnetic field computation and magnetic circuit computation. Software VECTOR FIELDS was used to set up 3D finite element model, and a magnetic circuit model was built specially for instantaneous release. The dynamic behaviors were computed combined with the electric circuit equation.更多还原
