A kind of vacuum circuit-breaker operating mechanism running-in machine, include the circuit breaker cradle base plate, described circuit breaker cradle base plate is provided with the double threaded screw of plural number, the double threaded screw upper end is provided with cover plate, the cover plate middle part is provided with perforation, central spindle of the spring passes cover plate, spring, spring base successively, and last central spindle of the spring passes the circuit breaker cradle base plate.
Further: described plural double threaded screw becomes circumferential arrangement, and cover plate is circular, and double threaded screw is fixed on its two ends with circuit breaker cradle base plate, cover plate respectively by nut, is provided with spring between cover plate and the circuit breaker cradle base plate.
Further: be provided with pad between described nut and circuit breaker cradle base plate, the cover plate, unclamp nut can on the cover board descend the two sides double-screw bolt place plus-minus pad.
Further: described central spindle of the spring near and the end that passes cover plate be connected with locking cap, central spindle of the spring near and the end that passes the circuit breaker cradle base plate be provided with pin-and-hole.
Further: the two ends of described spring respectively are provided with spring cup, near connecting spring base under the spring cup of circuit breaker cradle base plate.
Advantage of the present utility model is:
Stressing conditions when this vacuum circuit-breaker operating mechanism running-in machine utilization is simulated the work of vacuum breaker operation mechanism through the compression spring device that calculates, and make loading and unloading and adjust spring pressure simple and convenient, reach the purpose that replaces vacuum interrupter and pull bar.Long service life, simple in structure, loading and unloading easily, regulating spring pressure is realized the adjustment of pressure as required.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
