摘 要：基于电磁斥力原理的操动机构始动时间短，可由增加电流的简单方式提高动作速度，非常适合于快速开关的应用场合。采用有限元方法仿真分析了金属盘厚度、线圈盘盖板和底板材质对斥力驱动机构特性的影响，并研制了一台基于斥力驱动装置和永磁保持装置的12 kV直动式快速真空开关。经测试和优化，该开关分闸始动时间达到0.5 ms以内，满行程时间达到5 ms以内，提高了分闸速度并增加了可靠性。

Abstract: The actuator which is based on electromagnetic repulsion has a very short opening time, and can increase the opening speed by improving the coil current directly, so it is very suitable for the high-speed switch application area. The paper analyzed the effects of the drivingplate’s thickness, the material of the covering plate and the base plate on the characteristics of the electromagnetic repulsion driving unit using the FEM software, and designed a 12 kV vertical-type high-speed switch vacuum switch which consists of an electromagnetic repulsion driving unit and a permanent magnet force holding unit. After test and optimization, the opening time and the full-stoke time are less than 0.5 ms and 5 ms respectively, and the opening speed and the reliability are improved.
Key words: repulsion actuator; permanent magnet force holding; high-speed vacuum switch
