This paper presents a DC hybrid current-limiting breaker based on repulsion switch and rapid fuse, which can cover the shortages of the two kinds of exiting hybrid current-limiting device, the repulsion switch open the contact rapidly after short circuit, then the fault current is commutated onto the rapid fuse, the rapid fuse breaks the fault current and absorbs the energy. A 600A/640V DC hybrid current-limiting switch has been designed, an experiment with prospective peak current 100kA and time constant 7ms show that the repulsion switch open the contact after the fault current beyond the set value within 200us, the fault current is commutated onto the rapid fuse after 100us, then the fuse blows out after 1.1ms. The peak value of short-circuit current is 15.4kA and the switch recloses after the recovery within 50ms. The theoretical analysis and design of parameters has been proved by experimental results. These characteristics are useful for designing the Current-Limiting Switch in DC power systems.
