为了满足直流断路器的快速操作需求，由斥力执行器驱动的高速真空机械开关（VMS）受到关注。为了提高执行器的驱动速度和能量转换效率（ECE），研究了双面线圈斥力执行器的动态特性，并开发了两种针对驱动线圈的长宽比（定义为ARF）和电气参数（定义为EF）的广义优化设计方法。通过有限元仿真模型对VMS样机进行仿真和测试，验证了优化方法。结果表明，ARF方法可以将VMS的ECE从1.05%提高到7.55%，EF方法可以将同一VMS的ECE从1.05%提高到6.61%，ARF和EF的结合可以将VMS的ECE值提高到10.50%，从而证明了优化方法的有效性和准确性。
In order to meet the fast operation demands of DC circuit breakers, a high-speed vacuum mechanical switch (VMS) driven by a repulsive force actuator is focused. To improve the drive speed and energy conversion efficiency (ECE) of the actuators, the dynamic characteristics of the double sided coil repulsive force actuators are investigated, and two generalized optimization design methods focusing on the aspect ratio of the driving coils (defined as ARF) and the electrical parameters (defined as EF) are developed. FEM simulation models' simulation and tests of VMS prototypes are conducted to verify the optimization methods. Results prove that the ARF method could improve the ECE of a VMS from 1.05% to 7.55%, and EF method could improve ECE of the same VMS from 1.05% to 6.61%, the combination of ARF and EF could improve the value of VMS's ECE to 10.50%, thus proving the validity and accuracy of the optimization methods.
