| 摘 要： | 考虑端部母排的集肤效应和触头片间磁场的影响,采用三维瞬态非线性计算方法,对分片式触头系统的电动力进行了计算。计算结果显示,各分片触头片上的电流和电动力分布不均衡,靠外的触头片上的电流和电动力较大,靠内的触头片上的电流和电动力较小。

| Abstract: | With 3D transient nonlinear analysis,the electro-dynamic forces of sliced contact were calculated,in consideration of the skin effect and the influence of magnetic field.The calculated result shows that the current and electro-dynamic force are imbalanced in the slices,the current and force are bigger on the outside slices than that on the inside slices. |
