Abstract
The magnetic repulsive force which arises between a secondary short circuit ring and a primary coil through which short circuit current flows was used for a new magnetic puffer gas circuit breaker. A floating piston type magnetic puffer circuit breaker showed much success in experiments and the examples of theoretically calculated results together with a fixed piston type magnetic puffer circuit breaker are shown by the authors for the first time. It is proved that the interrupting performance of SF6 gas circuit breakers is much improved with the addition of a simple magnetic drive mechanism as shown in the following.Keywords
