  • Short circuit fault current limiter
    Patent number: 10756537
    Abstract: A short circuit fault current limiter includes a circuit breaker, a transfer current limiting unit and a current detection unit. The current detection unit is connected to the circuit breaker in series, and the circuit breaker and the transfer current limiting unit are connected in parallel into the power system line. An output terminal of the current detection unit is connected to a control terminal of the transfer current limiting unit. The current detection unit is configured to detect a fault current flowing through a branch of the circuit breaker under a short circuit fault operating condition and trigger the corresponding trigger switch of the transfer current limiting unit to be switched on, so that the circuit breaker is disconnected and the secondary side winding of the coupling reactor is connected to the system line in series, which is capable of rapidly limiting the amplitude of the fault current and reducing impact of the fault current on the system.
