Abstract
A drive mechanism for an energy accumulator of a stored energy circuit breaker includes a toothed ratchet wheel intermittently coupled to a shaft connected to an energy accumulating spring through a crank arm. A pair of drive levers are rotatably mounted upon the shaft and support a U-shaped drive claw and a pawl. The toothed periphery of the ratchet includes a gap wherein teeth are not formed. A drive spring biases the drive claw and pawl into engagement with the periphery of the ratchet, with the ratchet being positioned in the gap when the energy accumulating spring is fully charged. The drive levers are connected to one end of a connecting rod, the other end of which is connected to a motor assembly which causes reciprocating motion of the connecting rod when the motor assembly is energized. A lock means selectively prevents the shaft from rotating when the energy accumulating spring is fully charged. Activation of the lock means allows rotation of the shaft and discharge of the spring to operate on associated circuit breaker. The motor assembly is then automatically energized to rotate the ratchet via the connecting rod, friction lever and the drive claw to recharge the energy accumulating spring.
