Control mechanism for outdoor high voltage circuit breaker

The utility model relates to an outdoor high voltage breaker operation structure connected with 10KV supplying electricity lateral circuitry acting as control and protection function, comprising ratchet wheel drive structure, cam, principal axis connecting link structure, sector plate, half-axes structure and composite brake spring eccentricity seat. The sector plate and the active sub-rod of the principal axis connecting ink are respectively connected with two terminals of the arc plate. As the replacement drive part, the cam stores energy process acting on the replacement of the reamer link terminal drive sector between the sector plate and arc plate. The revolving axes and the principal connection ink provided with ''connect, separate'' character display plate is driving with the principal axis gear of the principal axis connecting link. This technology project has advantages of reliable in action and performance, safe in using.
