Abstract (en)
[origin: EP3229257A1] A circuit breaker locking device comprises an executing lever and a pressing plate, wherein a hole shaft of the executing lever is rotatably mounted in a base of a circuit breaker. An elastic piece is arranged between one end of the executing lever and the base, and the other end of the executing lever is provided with a locking end which can be connected with a locking portion at one side of the pressing plate in a locking manner. The pressing plate is mounted in the base and can rotatably oscillate relative to the base. The locking portion at one side of the pressing plate comprises an unlocking surface and a locking surface which correspond to the locking end respectively and are adjacent to each other, and a sliding step is arranged between the unlocking surface and the locking surface. A contact portion which is in contact connection with a circuit breaker operating mechanism is arranged at the other side of the pressing plate. A magnetic flux which can drive the pressing plate to oscillate is also arranged above the pressing plate correspondingly. The circuit breaker locking device provided by the utility model is firm in locking structure, stable in action process and simple in mechanical structure.
