The present invention relates to an electromagnetic repulsion actuator for a circuit breaker. The present invention comprises: a housing (10); a first fixed electrode (20) formed inside the housing (10) and having therein an operating space (21) opened to both sides; a pair of moving electrodes (50) installed on both sides of the operating space (21) of the first fixed electrode (20) to enable reciprocating motion, and conducted with the first fixed electrode (20); second fixed electrodes (60) spaced apart from the first fixed electrode (20) and installed on each of both ends inside the housing (10), and by being selectively in contact with the pair of moving electrodes (50) and being conducted with the pair of moving electrodes (50), thereby transmitting power supplied from one side to the other side. The operating coils (30, 40) generate magnetic force by means of an induced current and move the moving electrode (50) in the direction of being separated from the second fixed electrode (60). The present invention as above moves the moving electrode (50) by using an induced current generated by the close coil (30) and the open coil (40) to perform an open operation, and accordingly, the structure of a circuit breaker can be simple and the moving speed of the moving electrode (50) is increased. |
