Embodiment
For technological means, creation characteristic that the present invention is realized, reach object and effect is easy to understand, below in conjunction with embodiment, further set forth the present invention.
With reference to Fig. 1-8, this embodiment is by the following technical solutions: a kind of side-installed vacuum circuit breaker, comprise operating mechanism 1 and a major loop 2, a major loop 2 is installed on the framework rear side of miniaturization operating mechanism 1, a major loop 2 side direction installation side by side, arranges before and after operating mechanism 1 body; Described operating mechanism 1 comprises cabinet 3, energy storage and holding member, on/off switch parts, drive disk assembly, and described energy storage and holding member, on/off switch parts are main actuating parts, is arranged on operating mechanism 1 front side, and drive disk assembly is arranged on operating mechanism 1 rear side; A described major loop 2 can be pole, also can be arranged in insulating cylinder.
The vacuum circuit-breaker of this embodiment is realized the electric current that cuts off primary circuit under high-tension circuit, mainly contains three operations: 1, stored energy operation; 2, closing operation; 3, sub-switching operation, embodiment is as follows:
1. stored energy operation: energy storage motor 4 electric after, its output gear 4-1 rotate, output gear 4-1 rotate drive successively clutch gear 5-1, axle key gear 5-2, energy storage gear wheel 6 rotate; Thereby energy storage gear wheel 6 rotates stretching energy-stored spring 8; In the time that energy-stored spring 8 arrives peak and moves forward to certain position, roller 6-3 contacts with closing pawl 7, thereby will limit energy storage gear wheel 6 and continue motion, energy-stored spring 8 is remained on to extended state, top on the gear wheel of energy storage simultaneously 6 emits 6-1 promotion clutch gear 5-1 to make clutch gear 5-1 depart from axle key gear 5-2, and now the power supply of energy storage motor is cut off, and energy storage is complete, circuit breaker remains on energy storage position.
2. closing operation: after breaker energy storage, circuit breaker, in the time of open position, is given the combined floodgate release 11 combined floodgate signals of telecommunication, combined floodgate release 11 energized actions also promote closing pawl 7 and make itself and roller 6-3 disengaging; Now, energy-stored spring 8 is released, and energy storage gear wheel 6 rotates rapidly under the pulling force of energy-stored spring 8, thereby once drives energy storage axle 10, cam 17 to rotate; After cam 17 turns an angle, contact with output roller 18, and driver output roller 18 moves downward, output roller 18 moves downward and drives successively output clamping plate 16, a pin 15, link arm 20 to move downward; Link arm 20 drives input connecting lever 21, main shaft 25 to rotate; Main shaft 25 rotates and drives successively that transmission crank arm 27, transmission win 28 in succession, connecting plate connecting lever 29, input are won in succession 30, interlock is won in succession 31 travels forward; Win in succession 31 drives the tripping spring 34 that stretches of interlock drives three-phase connecting plate 32 to rotate simultaneously, and the moving block 33 that makes to be arranged on three-phase connecting plate 32 moves upward, thereby drives a major loop 2 to close a floodgate.When pin 15 moves downward after certain position, the sincere sub-portion of separating brake fills 12 the sincere sub-12-1 of separating brake and under a point position torsion spring 23 effects, will prop up pin 15 and remain on its draw-in groove internal limitations it moves upward, and makes circuit breaker remain on "on" position.
3. sub-switching operation: after breaker closing, give the separating brake release 13 separating brake signals of telecommunication, separating brake release 13 energized actions, and promote the sincere sub-portion of separating brake and fill 12 rotations, make it depart from a pin 15, now export that clamping plate 16, link arm 20, connecting lever 21, main shaft 25, transmission crank arm 27, transmission win 28 in succession, connecting plate connecting lever 29, input win 30 in succession, interlock is won in succession 31, three-phase connecting plate 32 is released, interlock is won in succession and 31 under tripping spring 34 effect, is driven each link counter motion, makes major loop 2 separating brakes one time; After certain position, cushion idler 37 contacts buffer, and each parts easy motion under the cushioning effect of buffer finally remains on open position.
More than show and described general principle of the present invention and principal character and advantage of the present invention.The technical staff of the industry should understand; the present invention is not restricted to the described embodiments; that in above-described embodiment and specification, describes just illustrates principle of the present invention; without departing from the spirit and scope of the present invention; the present invention also has various changes and modifications, and these changes and improvements all fall in the claimed scope of the invention.The claimed scope of the present invention is defined by appending claims and equivalent thereof.
