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
