| 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。

Development of 12kV Vertical-Type High-Speed Vacuum Switch |

| 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 driving-plate’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 12kV 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 0.5ms and 5ms respectively, and the opening speed and the reliability are improved. |
