本文介绍了永磁操动机构在真空接触器上的一种新应用。提出了一种用于驱动本安型低压真空接触器的新型永磁操动机构。永磁体安装在接触器的静电铁上,以增强其保持力和可靠性。真空接触器采用一个线圈分断,两个线圈串联,产生很大的磁动势,实现闭合动作。在仿真过程中,将电路方程、力学方程和磁场耦合起来。样机制造和测试,以验证和展示的接触器,这是配备了拟议的PM致动器的性能。
This paper reports a new application of permanent magnet actuator for vacuum contactors. A novel permanent magnet (PM) actuator to drive a vacuum contactor with intrinsically safe and low supply voltage is proposed. PM is mounted on the static iron of the contactor to enhance its holding force and reliability. While only one coil is used to break the vacuum contactor, two series coils are deployed to yield a high magnetomotive force to realize the making operation. The electrical circuit equation, mechanical equation and magnetic field are all coupled in the simulation. A prototype is manufactured and tested to validate and showcase the performance of the contactor which is equipped with the proposed PM actuator.
