description A short circuit current protection circuit is mainly used for the circuit damage caused by an overcurrent when the circuit is in short circuit, and a short circuit current is mainly and possibly a large current formed by the short circuit of the circuit. The protection circuit comprises the current limiting and protecting units, and each current limiting and protecting unit is composed of a circuit breaker switch and some series-wound current limiting elements. Different from the conventional short circuit protection device, the protection circuit can limit the intensity of the short circuit current, and also can cut off the power supply of the circuit generating a short circuit fault timely. The short circuit current protection circuit provided by the utility model can protect the overcurrent of a power transmission line caused by short circuit.
