Design of Electromagnetic Mechanism with Finite Element Method

Abstract:

A closing electromagnetic mechanism for rail transit direct-current circuit breaker is designed. But it is found that the temperature is too high when the mechanism kept closing for a long time because of the coils high power. Based on the theory of electromagnetic field and electromagnet design, the distribution of magnetic field and the electromagnetic force of electromagnetic mechanism are simulated by finite element analysis software ANSYS. An improved mechanism is manufactured according to the simulation results. The experiments show that the improved scheme can effectively reduce the electromagnetic mechanisms closing maintenance power, and the accuracy of simulation results is validated.
