Bullet operated circuit breaker mechanism

Structure and working principle: mainly composed of energy storage motor, closing spring, opening spring, connecting rod, crank arm, buffer and other components. After receiving the energy storage command, the motor is powered on to rotate, and through gear reduction and chain transmission, the closing spring stores energy. After the energy storage is in place, the closing mechanism locks the relevant components to maintain the energy storage state. When closing, the closing spring releases energy to drive the cam to rotate, completing the closing operation. At the same time, the opening spring is driven by the three-phase operating link to store energy. When the circuit breaker is opened, the opening spring releases energy to drive the separation of the moving and stationary contacts of the circuit breaker. When the circuit breaker is about to close, the oil buffer acts to absorb the remaining energy, and the bottom rubber buffer pad acts as a limit.
