Hybrid Circuit breaker with superconducting fault current limiter

摘要

A circuit breaker (10) comprising a superconducting fault current limiter (15) and a circuit breaker module (17) is described. The superconducting fault current limiter (15) and the circuit breaker module (17) are connected in series. The circuit breaker module (17) includes a disconnector, a first semiconductor switch unit, and a second semiconductor switch unit. The circuit breaker (10) can quickly and securely interrupt a circuit when an overcurrent fault occurs on the circuit.
