在交流接触器的优化设计中,动态特性分析是非常重要的。此外,活动触头和铁心回弹对接触器的寿命有显著影响。针对一种带反馈机制的智能接触器,建立了两组不同的周期传递方程。这些方程描述了考虑摩擦影响的电路、电磁场和机械系统的耦合。并利用虚拟样机技术,获得接触器的动态特性。本文引入接触电阻来研究触头的回弹。
In the optimum design of AC contactors, it is important to analyze the dynamic behavior. Moreover, movable contact and core bounces have remarkable effect on the lifetime of contactors. According to a kind of intelligent contactor with feedback mechanism, this paper builds two different sets of periodically inter-transferred equations. The equations describe the coupling of the electric circuit, electromagnetic field and mechanical system taking account of the influence of friction. And with virtual prototyping technology, the dynamic behavior of the contactor can be obtained. The paper introduces the contact resistance to investigate the bounce of the contact.
