Disclosed are a communication function-based synchronization detection method and device for a circuit breaker. A circuit breaker samples a voltage signal on one side and sends voltage information to a synchronization device in a communication mode (including a wired communication mode and a wireless communication mode), and the synchronization device only needs to sample a voltage signal on the other side and determines whether voltages on the two sides meet a synchronization condition so as to achieve a grid connection function. A data acquisition and processing circuit is omitted in a whole process, costs are reduced, and wiring is convenient.

Disclosed is a directional overcurrent protection method of a circuit breaker, comprising fault direction determination, fault arbitration, and execution of a trip action. The directional overcurrent protection method of the circuit breaker can achieve the overcurrent directional protection only by means of an algorithm on the basis of the acquisition of voltage and current at an output side of the circuit breaker. Hardware costs are not increased because only the voltage and current at the output side of the circuit breaker need to be acquired.
