Abstract

A closing electromagnetic mechanism for rail transit direct-current circuit breaker is designed.But it is found that the temperature-rise is too high when the mechanism kept closing for a long time because of the coil’s 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.A improved mechanism is manufactured according to the simulation results.The experiments show that the improved scheme can effectively reduce the electromagnetic mechanism’s closing maintenance power

and the accuracy of simulation results is validated.
