ABSTRACT

In this paper, we study the application of Maxwell 3D and ADAMS software for simulation and analysis of electromagnetic system, with UG software for AC contactor and main contact system of electromagnetic system. We then study the influence of harmonic on type CJX2-40 AC contactor main contact system and operation characteristics. To establish a three-dimensional finite element model of electromagnetic mechanism of AC contactor, we take Maxwell 3D software, on the model of finite element mesh, the calculation of different closing sine excitation and containing under harmonic excitation angle electromagnetic system. For the static and dynamic characteristics of AC contactor, static magnetic field distribution and the suction characteristic curve drawing, we do a comparative study of the results of the simulation, analysis of the influence of harmonics on the AC contactor motion characteristics.
