摘要
针对接触器吸合时动静铁心碰撞以及动静触头的振动会降低接触器的机械寿命和电寿命的问题,从接触器电磁系统的结构型式考虑,采用正交试验的方法来优化电磁系统的结构。首先,利用电磁场仿真软件建立电磁系统的模型。然后,通过正交试验的方法,研究动静铁心的不同部位尺寸对动静触头闭合速度、动静铁心闭合速度、动铁心动能的影响,并对仿真的结果进行极差分析和追加试验。最后,通过优化减轻了触头的振动,减小了动静铁心的吸合速度和动静铁心吸合时动铁心能量,提高了接触器的机械寿命和电寿命,为交流接触器电磁系统的优化提供了可靠的方法。
In view of the problem that the mechanical life and electrical life of the contactor are reduced by the collision of the moving core and the static core and the vibration of the moving contacts and the static contacts when the contactor is closed,the orthogonal test method was adopted to optimize the structure of the electromagnetic system considering the structural type of the electromagnetic system of the contactor.Firstly,the model of electromagnetic system was established by electromagnetic field simulation software.Then,through the method of orthogonal test,the influence of different parts of the moving core and the static core on the closing speed of the moving contacts and the static contacts,the closing speed of the moving core and the static core and the kinetic energy of the moving core were studied,and the range analysis and additional test were carried out for the simulation results.Finally,the vibration of the contacts was reduced by optimization,the speed of the moving core and the static core and the energy of the moving core were reduced,the mechanical life and electrical life of the contactor were increased,and a reliable method is provided for the optimization of the electromagnetic system of AC contactor.
