Abstract
A high-voltage circuit breaker and an actuator mechanism thereof. Moving contact insulation pull rods of high-voltage circuit breaker units are driven into action by a crankshaft. A main journal of the crankshaft is transmissively connected at an output end of a power apparatus, thus causing the power apparatus to input a rotary torque to the entire crankshaft. The moving contact insulation pull rods are rotatively fitted onto a rod journal of the crankshaft, thus allowing, when the crankshaft is rotating, for the moving contact insulation pull rods to make reciprocal movements within the high-voltage circuit breaker units under the push-pull effects of the rod journal of the crankshaft. The moving contact insulation pull rods of three high-voltage circuit breaker units are pulled into action simultaneously, thus the high-voltage circuit breaker units are driven by the rotation of the crankshaft to make contact-opening/closing movements. Therefore, when the contacts of the high-voltage circuit breaker are opening/closing, the power apparatus and the crankshaft always rotate in one rotary direction. This is different from the form that a rotary motor and a lever need to rotate in the forward/reverse directions, thus solving for the high-voltage circuit breaker the problem of shortened service life and poor operational reliability.
