Dynamic Analysis of the PM-type Magnetic Circuit Breaker Using Magnetic Euivalent Circuit

This paper describes the operating characteristic analysis of PM-type magnetic circuit breaker for electromagnetic field, electric circuit and mechanical motion problems. Transient calculations are based upon the magnetic equivalent circuit analysis including non-linearity of materials and using iteration routines. The analysis results of this magnetic equivalent circuit are compared with those of FEM.
