Fig. 9 is that the spring mechanism movement of external certain company is not intended to.
Embodiment as shown in Figure 1, circuit breaker is installed on the pedestal 52 by three poles 51, control cubicle 53 is lifted on above the pedestal between two parties, and spring operating mechanism and electric control unit are housed in the cabinet.
As shown in Figure 2, operating mechanism comprises gear train assembly, is made up of motor gear 1, gear 2, shaft gear 3, gear 4, shaft gear 5, gear 6; The energy storage clutch keeps pallet 12, switching-in spring 25 to form by energy storage axle 7, cam 8, roller 9, driving ratchet 10, baffle plate 11, energy storage; Close a floodgate to keep the connecting lever interconnected system, by combined floodgate semiaxis 13, closing by hand handwheel 14, closing coil 15, output pull bar 16, separating brake semiaxis 17, manual brake separating handwheel 18, switching winding 19, close a floodgate keep pallet 20, little axle 21, fastener 22, oil bumper 23, tripping spring 24, roller 26, output shaft 27, closing a floodgate keeps connecting lever 28, roller 29 and output toggle arm 30 etc. to form.This operating mechanism drives 7 rotations of energy storage axle by motor by the tertiary gear transmission and makes switching-in spring 25 energy storage.
As shown in Figure 3, three of gear train assembly pairs of gears (motor gear 1, gears 2; Shaft gear 3, gear 4; Shaft gear 5, gear 6) unilateral bearing 31 is installed on the power transmission shaft, make motor in the process of energy storage, gear can only rotate toward the direction, and can not turn round, make switching-in spring when the distortion compression, gear drive can not make the reaction force of switching-in spring cause the gear counter-rotating because of the motor outage.
As Fig. 4, shown in Figure 5, the energy storage clutch comprises energy storage axle 7, drives ratchet 10, baffle plate 11.When gear wheel 6 rotates (because gear wheel 6 is connected with energy storage pawl base 42 usefulness screws 44, energy storage pawl base 42 is connected with pivot pin 43 with driving between the ratchet 10), drive ratchet 10 and drive eccentric wheels 41 (owing to being connected with spline between eccentric wheel 41 and the energy storage axle 7), eccentric wheel 41 drives energy storage axle 7 and rotates and energy storage, when driving ratchet 10 is run into plate washer 11, drive ratchet 10 long-armed lifting, break away from eccentric wheel 41, gear 6, energy storage pawl base 42 and 10 idle running of driving ratchet, and eccentric wheel 41 and energy storage axle 7 stop operating.State as shown in Figure 4.
It as shown in Figure 6, (c)-(a)-(b)-(d) is cam link operating principle schematic diagram.
Wherein (a) figure is a separating brake energy storage state; (b) be the not energy storage state that closes a floodgate; (c) be combined floodgate energy storage state; (d) be not energy storage state of separating brake.
Closing operation: after the switching-in spring energy storage of mechanism finishes, mechanism is in state shown in Fig. 6 (a), simultaneously referring to Fig. 2 movement cutaway view, switching-in spring 25 remains on the energy storage position because of energy storage keeps the effect of pallet 12, energy storage keeps the trend of the pallet 12 oriented direction of triping (counterclockwise) motion under the effect of roller 9, this moment is if operation closing by hand handwheel 14 makes it by counterclockwise rotating, or be subjected to electronic work by closing coil 15, make combined floodgate semiaxis 13 rotate counterclockwise an angle, thereby cause energy storage to keep pallet 12 to thread off, switching-in spring 25 releases energy and drives cam 8 and rotate counterclockwise, ordering about closes a floodgate keeps connecting lever 28 and output toggle arm 30 to clockwise rotate simultaneously, output pull bar 16 moves upward and drives the rotation of circuit breaker connecting lever axle, when keeping pallet 20 to be pinned when closing a floodgate by the little axle 21 of fastener 22, combined floodgate is finished, meanwhile, roller B26 restriction energy storage keeps pallet 12 to rotate, can not close a floodgate once more, (prevent sky from closing and mechanism is damaged), output shaft 27 is by the switch on it simultaneously, switch auxiliary switch, cut off the closing circuit power supply, the divide-shut brake indicating device points to closing position.
When combined floodgate was finished, travel switch was connected, and thermal energy storage process promptly begins, and in the time of combined floodgate, tripping spring 24 is compressed, and the energy that stops that closes a floodgate is absorbed by tripping spring 24 and oil bumper 23, for separating brake is got ready.
Sub-switching operation: Fig. 6 (b) after mechanism closes a floodgate, simultaneously referring to Fig. 2 movement cutaway view, close a floodgate and keep pallet 20 under the effect of circuit breaker load force, contacting piece 22 has a counterclockwise torque, it keeps balance because of the reaction force of separating brake semiaxis 17, if this moment is operation manual brake separating handwheel 18, make it to rotate counterclockwise, or switching winding 19 is subjected to, promote separating brake semiaxis 17 and rotate counterclockwise an angle, fastener 22 makes thereupon rotating counterclockwise to close a floodgate and keeps pallet 20 to thread off, and output toggle arm 30 and close a floodgate and keep connecting lever 28 to rotate counterclockwise under the effect of tripping spring 24 makes breaker open operation such as Fig. 6 (d), meanwhile output shaft 27 rotates, auxiliary switch switches, and cuts off the sub-gate circuit power supply, and drives indicating device in the separating brake position.
Automatic reclosing: mechanism provides the separating brake instruction when combined floodgate energy storage state such as Fig. 6 (c), and tripping spring orders about breaker open operation, and after 0.3 second, the switching-in spring of energy storage orders about breaker closing.After combined floodgate was finished, tripping spring was compressed energy storage simultaneously, provided the separating brake instruction once more, and circuit breaker is separating brake immediately, and whole automatic reclosing is finished.
As shown in Figure 7 and Figure 8, simultaneously referring to Fig. 2 movement cutaway view, closing a floodgate keeps the function of connecting lever 28: this connecting lever plays the function aspect four in entire mechanism, maximally utilise this part, makes the number of spare parts of whole mechanism reduce, and volume is reduced.
C, angle are installed to close a floodgate and are kept pallet 20, and when mechanism was in "on" position, closing a floodgate kept contacting and make it remain on "on" position between pallet 20 and the fastener 22.
D, while are equipped with oil bumper 23 thereon, the effect of play branch, closing a floodgate and cushioning.
The function of fastener: separating brake fastener 22 mainly plays the effect that subtracts power when separating brake, and this mechanism adopts one-level to subtract power, has only adopted a fastener, has simple, effect reliably.Other mechanisms generally adopt two-stage to subtract power when separating brake subtracts power at least both at home and abroad at present.The original structure part is many, and it is unreliable to subtract power.
