Abstract

According to the requirements of three phase permanent magnetic actuator circuit breaker

its supporting permanent magnetic actuator needs to be miniaturization and low voltage

low current

big retentiveness and other special requirements

designing and developing a new permanent magnetic actuator.The main research in this article is that the relationship between the displacement

speed and other mechanical parameters of permanent magnetic actuator dynamic iron core in switching process to the time in low voltage of points

and the determination of parameters optimization such as the coil current and static keep force etc.Based on the finite element method

the analysis of permanent magnet actuator is researched; the permanent magnetic actuator simulation model in Maxwell 2D is established

and according to the simulation results combined with prototype data of three-phase discrete permanent magnetic actuator optimization design is made.Test results show that the various technical parameters of the optimized permanent magnetic actuator meet the design requirements.
