Simulation Analysis and Experimental Verification on Static Characteristics of AC Contactor
The calculation of static characteristics of AC contactor is the core of electromagnetic system design.Taking a type of three-phase AC contactor as an example,the finite element software COMSOL Multiphysics is applied to simulate the coil current,the flux linkage and the electromagnetic attraction under the condition of fixed magnetic gap,and the energy conversion relationship is studied through the extracted active power and reactive power.The influence of coil voltage and magnetic gap on electromagnetic attraction is analyzed.The experimental results are in good agreement with the simulation results.
