Abstract

In order to improve the performance of circuit breakers（CBs）

the influence of permeable property of material on permanent magnetic actuators’（PMA）dynamic characteristic are researched

and the finite element method（FEM）is used to establish the electromagnetic-mechanical coupled model.The electromagnetic equation

electric circuit equation and mechanic equation are solved to study operating process of PMA.The yoke iron of PMA is made of cold-rolled silicon steel sheet and electrical pure iron respectively

the curves of the PMA parameters changing with time are obtained.The results show that the PMA with cold-rolled silicon steel sheet has better speed performance and less eddy current loss.A vacuum circuit breaker with cold-rolled silicon steel sheet PMA is carried out

and in the corresponding experiments the operating characteristics are measured and the exciting current curves are also obtained.It is confirmed that the simulation results are accurate and have certain actual significance.
