Permanent magnet material properties change will inevitably affect the performance of contactor operation

Magnet contactor by conventional electromagnetic contactor evolved a new contactor, it uses the new works, to overcome the traditional electromagnetic contactor energy consumption, operating noise, by the impact of the grid voltage and large shortcomings. However, the performance of permanent magnetic materials susceptible to temperature effects and changes in material properties of permanent magnet contactor operation will inevitably affect the performance. Traditional  Circuit breaker  contactor development for a long time, the theory and dynamic characteristics of more mature. But now on permanent contact with the dynamic characteristic simulation research literature is relatively small, and did not consider at different  Voltage stabilizer  impact of changes in material properties. Therefore, this paper developed for the laboratory's permanent nominal current 63A contactors, considering different temperature changes in performance permanent magnetic materials, the establishment of the finite element model and the simulation model, at different temperatures Magnet contactor operating characteristic simulation analysis work, get action performance curve.
