The utility model is installed on the circuit breaker, and set forth execution mode with reference to accompanying drawing 1～8: the left side is a combined floodgate modular unit 91 in the accompanying drawing 1, and the right is a separating brake modular unit 81; Wherein, breaker closing institute energy requirement is provided by energy storage compression spring 10 energy storage compression, and the energy storage of energy storage compression spring 10 both can be accomplished by the external power source drive motors, also can use the energy storage handle manually to accomplish.
Stored energy operation: the energy storage motor 16 by being fixed on the side plate carries out energy storage, perhaps the energy storage handle is inserted to shake counterclockwise in the manual energy storage hole and carries out.When electric energy-stored: drive sprocket wheel 14 by energy storage motor 16 output shafts; Manually drive sprocket wheels 14 transmissions through worm gear 11 and worm screw 13 during energy storage.When energy storage drive sprocket 6 rotates, promote slide block, energy storage axle 7 is followed rotate and carry out energy storage through connecting lever 5 compressed energy-storages compression spring 10 through pin; When arriving the energy storage position; Gag lever post on the framework is depressed slide block makes energy storage axle 7 and sprocket wheel 14 throw off transmission; Energy storage keeps pallet 9 to withstand roller and keeps the energy storage position; The axle of energy storage simultaneously 7 upper plates 24 drive energy storage direction board 25 flip displays " energy storage " mark and switch energy storage and put switching in place with sensitive switch 1 cut-out energy storage motor 16 power supplies, and this moment, circuit breaker was in the combined floodgate SBR.
Closing operation; Make making electromagnet 12 actions no matter press " combined floodgate " button or remote operation, all can make energy storage keep trip shaft 19 to rotate, make pallet unclamp roller with hand; Switching-in spring discharges simultaneously and through connecting lever the cam 22 on energy storage axle 7 and the axle is rotated; Cam 22 drives main shaft linkage drive insulated tension pole and moving contact entering closing position on the framework again, and the compression contacts spring, keeps the required contact pressure of contact.
After feed motion was accomplished, closing a floodgate kept pallet and separating brake semiaxis 30 to keep closing positions, the energy storage motor 16 current supply circuits connection that resets of the direction board of energy storage simultaneously 25, energy storage auxiliary switch.If external power supply also connects the energy storage state that then gets into once more, connecting plate drawing separating brake direction board 33 demonstrates the mark of " closing ", and the pulling of transmission connecting plate realizes that master subswitch switches.
In the time of sub-switching operation, both can also can make separating brake release electromagnet or the action of overcurrent release electromagnet make combined floodgate keep pallet and 30 releases of separating brake semiaxis to realize sub-switching operation by " separating brake " button through connecting external power source; By touch spring and sluice separating spring energy stored the arc control device dynamic/static contact is separated.At separating brake process back segment, absorb separating brake process dump energy and limit the separation point position hydraulic bjuffer; Demonstrate " branch " mark by connecting plate pulling on/off switch direction board 33, spur counter simultaneously, realize rolling counters forward, switch by transmission connecting plate pulling master subswitch; Modular mechanism can provide perfect anti-misoperation function, and is easy to use.
After the modular mechanism closing operation was accomplished, the interlocking bent plate 27 that closes a floodgate moved downward and fastens combined floodgate, and combined floodgate bent plate 26 states on the retainer shaft can not close a floodgate during separating brake at circuit breaker once more.
Owing to the accidental cause separating brake, if reclosing command keeps always, the inner anti-jump control loop of circuit breaker will cut off closing circuit, prevent multiple shot reclosing after breaker switching-on operation.
Handcart type breaker is moved upward and is fastened combined floodgate by interlocking bent plate 27 when not arriving test position or service position, and combined floodgate bent plate 26 positions on the retainer shaft cut off closing circuit simultaneously, prevents that circuit breaker is in "on" position and gets into loading zone.
Handcart type breaker is pressed the propulsive mechanism jam plate by the roller on the framework main shaft behind service position or test position combined floodgate, handcart can't move, and prevent to advance or pull out loading zone in "on" position.
When selecting electric closing locking function for use, do not stop closing operation making under the locking device release situation.
The secondary line of each Quadratic Finite Element device is connected on the binding post plug 36 according to its function in advance on the modular springs operating mechanism, and on circuit breaker frame, its secondary line is connected on the corresponding binding post plug 36 and connects with binding post socket 40 predetermined fixed; When modular mechanism is installed to circuit breaker frame when getting on, its binding post plug 36 automatic butt need not to remove its secondary line of pegging graft again by hand to binding post socket 40, and are easy to operate, thereby realize the purpose of the utility model.
Those skilled in the art's simple change and replacement in this area all are within the protection range of the utility model.
