More Information
Summary:The invention discloses a circuit breaker and an operating mechanism thereof, the operating mechanism comprises a mounting rack and an execution shaft rotatably mounted on the mounting rack, and an elastic piece is arranged between the mounting rack and the execution shaft; the operating mechanism further comprises a driving piece and a connecting rod assembly, the driving piece is used for driving the connecting rod assembly to act so as to drive the execution shaft to rotate to a closing position, and the elastic piece can store energy in the process that the execution shaft rotates to the closing position. The connecting rod assembly can act under the action of external thrust and the elastic piece so as to drive the execution shaft to rotate from the switching-on position to the switching-off position. The operating mechanism adopts a non-energy-storage pure mechanical structure, so that the structure of the operating mechanism of the circuit breaker is effectively simplified, process requirements and ass
