Embodiment 1
[0024] Embodiment 1 of the operating mechanism of the circuit breaker of the present invention includes a locking system for energy storage tripping. The structure of the locking system is as follows Figure 1-2 As shown, the main crank arm 18 and the electromagnet are included, and a latch structure is arranged between the main crank arm 18 and the electromagnet. The main crank arm 18 is fixedly connected to the switch pull rod 20 and can rotate with the switch pull rod 20 . The detent 15 is hinged on the main crank arm 18 through the hinge shaft 16 , and the main crank arm 18 is also provided with a torsion spring 17 for providing the detent 15 to rotate clockwise. Wherein the detent 15 is provided with a waist-shaped hole 14 , and the main crank arm 18 is also provided with a limiting pin 19 extending into the waist-shaped hole 14 to limit the rotation angle of the detent 15 . When the switch pull rod 20 rotates counterclockwise under the action of the drive motor, the en...
