The front of housing is provided with the toggle switch 34 for starting or turn off central control circuit；The upper end of housing is provided with signal terminal 35, and central control circuit is connected with signal terminal 35.
In the present embodiment, two leaf switch are fixedly installed on the same wall of circuit board, and live apart the both sides of circuit board in the cam linkage portion 53 of two leaf switch and linkage turbine.
In the present embodiment, the portion perimeter wall of linkage gear 6 being just provided with linkage tooth 61, the present embodiment selects to arrange linkage tooth on the wall body of 1st/to three/6th of linkage gear periphery wall, can be preferably further one of four parts.
The work process of the present embodiment is as follows: first passes through holding wire and connects signal terminal 35 and external intelligent electric meter, and the toggle switch 34 on automatic divide-shut brake driving device housing front is dialed to ON position so that central control circuit normal operation.
When being in expense normal operating condition, each chopper is in "on" position, and the separating brake dropout gangbar 251 in each chopper is in quasi-dropout position；The driving contact face 821 of now dropout STATEMENT OF FEDERALLY SPONSORED 8 is connected on the transition part 533 of linkage turbine 5 cam linkage portion 53, in dropout STATEMENT OF FEDERALLY SPONSORED 8, the spacing angle 831 in driving lever portion 83 is not to separating brake dropout gangbar 251 applied thrust, the driving tooth 521 of linkage turbine middle gear drive division 52 is now not exposed to linkage gear, linkage gear is substantially in clutch state with linkage turbine, the now positive and negative rotation of linkage gear all will not be subject to the obstruction of linkage turbine, therefore under this kind of state, automatic divide-shut brake driving device will not hinder the rotation of divide-shut brake handle in breaker body, divide-shut brake handle now is free to carry out electronic breaking-closing operating, namely can freely carry out manual breaking-closing operating.
When, after subscriber arrearage, external intelligent electric meter sends signal to the central control circuit on circuit board；Drive motor rotates, by driving turbine 41 to drive linkage turbine rotation；Described linkage turbine rotates along clockwise direction, protuberance 534 in cam linkage portion also rotates clockwise therewith, owing to the radius in sideline, protuberance periphery is more than the radius in sideline, transition part 533 periphery, therefore protuberance is when replacing recess to be connected on driving contact face, the drive link portion of dropout STATEMENT OF FEDERALLY SPONSORED is played a driving role, and dropout STATEMENT OF FEDERALLY SPONSORED rotates around it centre bore 81 and rotates clockwise；When the turbine that links is rotated further until when the driving tooth 521 of the turbine middle gear drive division 52 that link will touch the linkage tooth of linkage gear, in now dropout STATEMENT OF FEDERALLY SPONSORED, separating brake dropout gangbar has been stirred in driving lever portion, make it from quasi-dropout bit jitter to raw bits, each chopper is made to transfer tripped condition to from gate-dividing state moment, it is achieved arrearage fast trip action；When separating brake dropout STATEMENT OF FEDERALLY SPONSORED moves to raw bits, dropout STATEMENT OF FEDERALLY SPONSORED locks separating brake dropout gangbar spacing in raw bits also by its spacing angle；If now being pulled divide-shut brake handle to closing position by external force, once remove external force, divide-shut brake handle will automatically return to sub-gate position, therefore can not realize feed motion；If now turning off toggle switch, due to electric motor circuit breaking akinesia, separating brake dropout gangbar is still in lock-out state, and user still can not carry out closing by hand action；The power transmission therefore the present embodiment can close a floodgate after effectively preventing subscriber arrearage privately.
When user's paying no longer arrearage, owing to locking spacing firmly separating brake dropout gangbar before this, want to close a floodgate, gangbar of separating brake have to being threaded off is unlocked action: drive motor rotates, linkage turbine rotation is driven by its turbine, under the combined effect of reseting groove 531 and reset breach, one jiao of the protuberance adjacent with reseting groove 531 can embed in the reset breach of dropout STATEMENT OF FEDERALLY SPONSORED, so that the driving contact face 821 of dropout STATEMENT OF FEDERALLY SPONSORED can be connected on the periphery wall of recess 532 in cam linkage portion；Now, driving lever portion is because of rotary space, it is impossible to be enough further continued for locking separating brake dropout gangbar, thus realizing filling expense combined floodgate released state, ensure that chopper does not have dropout phenomenon in making process, namely ensure that chopper does not have the phenomenon closing not brake application in making process；Additionally, now if owing to reason is put in the position of chopper self, such as storing reverse with normal mounting state described above, when causing this unblock moment, the driving contact face 821 of dropout STATEMENT OF FEDERALLY SPONSORED fails to be connected on the periphery wall of the recess 532 in cam linkage portion, also it is do not affect unblock effect, because when next step carries out filling expense feed motion, separating brake dropout gangbar to move to quasi-dropout position from raw bits, separating brake release lever will promote the spacing angle of dropout STATEMENT OF FEDERALLY SPONSORED, the driving contact face 821 making dropout STATEMENT OF FEDERALLY SPONSORED is connected on the periphery wall of recess 532 in cam linkage portion.
Owing to relieving the locking to separating brake dropout gangbar before this, and the driving tooth of the gear drive division 52 of linkage turbine starts the linkage tooth with linkage gear and engages, linkage turbine begins through gear drive division and drives linkage gear to rotate, and drives the divide-shut brake handle in each chopper to carry out feed motion thereby through output main shaft；Hereafter, drive motor is rotated further, and drives linkage turbine rotation to original position.
When subscribers' line is overhauled by needs, chopper is needed to be in gate-dividing state, now preferably toggle switch is dialed to "Off" position, such benefit is to turn off central control circuit, the ability of drive motor out of hand operating, preventing in maintenance process, the control because being subject to remote signal makes chopper carry out feed motion, causes electric shock accidents.
The present invention has following technical effect that (1) is by changing linkage gear as sector gear into from traditional full-depth tooth gear, it is to avoid full-depth tooth gear is under switch "on" position, and linkage turbine is misrouted the dynamic linkage gear that may result in and kowtowed that conjunction is locked, damages.(2) induction mode is changed into use leaf switch by traditional Hall element, effectively reduces electromagnetic interference, and improves contact repetitive positioning accuracy.
