A drive mechanism for vacuum interrupter is exported to circuit breaker

The utility model provides a technical scheme is that a drive mechanism for vacuum interrupter is exported to circuit breaker, technical problem that the mechanical efficiency of solve circuit breaker transmission link is low adopts including the install bin box in drive mechanism's the structure, mechanism's output shaft of circuit breaker is located one side of box along the horizontal direction, and vacuum interrupter's insulated tension pole is located the top of box along vertical direction, also include in drive mechanism's the structure: both ends are fixed respectively and are connected with the help of the pivot at middle transmission axle and mechanism's epaxial upper and lower turning arm of output with the help of the middle transmission axle of revolute pair horizontal spacing in the box, pass the spacing insulated tension pole bottom of spacing slide opening at box top and realize the floating connection with the help of the locating pin subassembly that floats with the middle transmission axle. The utility model discloses the motion of middle transmission axle is more nimble, has reduced the frictional dissipation of circuit breaker in the transmission link like this, has improved the conversion efficiency of energy, has improved the running life of circuit breaker.
