摘 要:企业的重要设备如微特电机、精密仪器等对供电质量要求很高,由于故障等原因引起的瞬间电压低落或者停电会严重影响产品的合格率。传统的高效UPS供电中,采用大功率电力电子器件存在着价格昂贵、运行损耗大等问题。本文提出一种采用斥力机构与永磁机构混合使用的高速接触器,动作迅速可靠,通流量大。采用Ansys对其进行了有限元仿真,对仿真结果进行了相关分析,并在此基础上制作了样机。通过机械实验表明,新型高速接触器能很好地完成工作。Enterprise's important devices such as micro motor, precision instrument and so on, demand high quality power transmission. Instant voltage-downcast due to line-fault or power failure will reduce the yield of production. In traditional high-efficiency UPS supply, the price of power electronic devices is expensive and running losses is high whose loss-heat can damage to components because of semiconductor's long-time working. So a high-speed contactor consists of repulsion actuator and permanent magnet actuator is presented in this paper, which can act re- liably by high speed and has big current-transit capacity. When the power faults occur, the high-speed contactor will break quickly, and a power electronic device which is parallel with it will finish the remaining task. Ansys soft- ware is used for finite element simulation, and the results are analyzed, based on which the model machine is man- ufactured. Finally, test shows that the novel contactor can move fast, and the energizing time is very short which can ensure the compensation system work successfully.
