ABSTRACT:
A high-speed current limiting circuit breaker comprises a self-recovery type current limiting element for limiting a fault current, a parallel resistance connected in parallel with the self-recovery type current limiting element and a circuit breaker connected in series with the self-recovery type current limiting element, a fault voltage detector for detecting the voltage generated on the parallel resistance and thereby driving an electromagnetic repulsion coil for breaking the circuit breaker.
