Although in recent years, the electromagnetic repulsion mechanism based on the eddy current repulsive force quickly become a hotspot, the mechanism can't apply to circuit breaker of long clearance between open contacts and high voltage. So it's vital to find a new one used for circuit breaker of long clearance between open contacts. In this dissertation, a new fast repulsion mechanism of double-coil-structure...
Multi-stage reconnection electromagnetic launcher is not a simple addition of some single-stage launching systems, there is a stage coupling between each driving coils. In this paper, the mathematical models of single and multi-stage reconnection electromagnetic launchers are described in detail, and the interstage coupling at different velocities is discussed respectively. The inter-stage coupling...
