The present invention is installed on-board the circuit breaker, sets forth execution mode with reference to accompanying drawing 1 ~ 8: in accompanying drawing 1, the left side is combined floodgate modular unit 91, and the right is separating brake modular unit 81; Wherein, breaker closing institute energy requirement is compressed by energy storage Compress Spring 10 energy storage to be provided, and the energy storage of energy storage Compress Spring 10 both can be completed by external power source drive motors, and energy accumulation handle also can be used manually to complete.
Stored energy operation: carry out energy storage by the energy storage motor 16 be fixed on side plate, or energy accumulation handle to be inserted in manual energy storage hole shake counterclockwise and carry out.Time electric energy-stored: by energy storage motor 16 output shaft band movable sprocket 14; Movable sprocket 14 transmission is with by worm gear 11 and worm screw 13 during manual energy storage.When energy storing drive sprocket wheel 6 rotates, promote slide block by pin, energy storage axle 7 is followed and rotates and carry out energy storage by connecting lever 5 compressed energy-storage Compress Spring 10; When arriving energy storage position, gag lever post pressure slide block on framework makes energy storage axle 7 and sprocket wheel 14 throw off transmission, energy storage keeps pallet 9 to withstand roller and keeps energy storage position, simultaneously energy storage axle 7 upper plate 24 drives energy storage direction board 25 flip displays " energy storage " to mark and switches the energy storage switching sensitive switch 1 that puts in place and cuts off energy storage motor 16 power supply, and now circuit breaker is in combined floodgate standby condition.
Closing operation, no matter press " combined floodgate " button with hand or remote operation makes making electromagnet 12 action, energy storage all can be made to keep trip shaft 19 to rotate, pallet is made to unclamp roller, switching-in spring release makes the cam 22 on energy storage axle 7 and axle rotate by connecting lever simultaneously, cam 22 again on driver framework spindle bar-linkage mechanism drive insulated tension pole and moving contact to enter closing position, and compression contacts spring, keeps contact needed for contact.
After feed motion completes, close a floodgate and keep pallet and separating brake semiaxis 30 to keep closing position, the direction board of energy storage simultaneously 25, energy storage auxiliary switch reset energy storage motor 16 current supply circuit are connected.If external power supply is also connected, again enter energy storage state, connecting plate drawing separating brake direction board 33, demonstrates the mark of " conjunction ", and transmission connecting plate pulls and realizes master subswitch switching.
When sub-switching operation, both can pressing " separating brake " button, and also having made separating brake release electromagnet or the action of overcurrent tripping electromagnet make combined floodgate keep pallet and separating brake semiaxis 30 to unlock and realize sub-switching operation by connecting external power source; The energy stored by touch spring and sluice separating spring makes arc control device dynamic/static contact be separated.At separating brake process back segment, absorb separating brake process dump energy by hydraulic bjuffer and limit separation point position; Pull on/off switch direction board 33 to demonstrate " dividing " mark by connecting plate, pull counter simultaneously, realize rolling counters forward, pull master subswitch to switch by transmission connecting plate; Modular mechanism can provide perfect anti-misoperation function, easy to use.
After modular mechanism closing operation completes, the interlocking bent plate 27 that closes a floodgate moves downward and fastens combined floodgate, combined floodgate bent plate 26 state in retainer shaft, can not again close a floodgate when the non-separating brake of circuit breaker.
Due to accidental cause separating brake after breaker switching-on operation, if reclosing command keeps always, the anti-jump control loop of circuit breaker internal will cut off closing circuit, prevent multiple shot reclosing.
Handcart type breaker is not when arriving test position or service position, and moved upward by interlocking bent plate 27 and fasten combined floodgate, combined floodgate bent plate 26 position in retainer shaft, cuts off closing circuit simultaneously, prevents circuit breaker to be in "on" position and enters loading zone.
Handcart type breaker is after closing a floodgate in service position or test position, and press propulsive mechanism jam plate by the roller on framework main shaft, handcart cannot move, and prevents from advancing or pull-out loading zone in "on" position.
When selecting electric closing locking function, do not make to stop closing operation in locking device unblock situation.
On Modular spring operating mechanism, the secondary line of each Quadratic Finite Element device is connected on binding post plug 36 according to its function in advance, is fixed in advance in circuit breaker frame by connecting terminal socket 40, and its secondary line is connected on corresponding binding post plug 36 and connects; When modular mechanism be installed to circuit breaker frame get on time, its binding post plug 36 automatic butt, on connecting terminal socket 40, removes its secondary line of grafting again without the need to manual, easy to operate, thus realizes object of the present invention.
The simple change of those ordinary skill in the art and replacement are all within protection scope of the present invention.
