초록

In this paper, a new design of permanent magnetic actuator (PMA) for vacuum circuit breaker (VCB) with one coil is proposed. Electromagnetic characteristic analysis is performed numerically using finite element method (FEM) considering the nonlinearity of magnetic core and permanent magnet. The characteristics of proposed PMA with one coil is similar with that of the conventional PMA with two coils. The proposed PMA can simplify the control circuit because of the usage of one coil. Therefore, the reliability of VCB can be improved with the proposed model.
