One end from newel post 1 is fixed in newel post 2 14, and newel post 2 14 is fixed on insulating base 1.
It is fixedly installed bearing block 15 on insulating base 1, regulation handle 16, regulation handle are movably set in bearing block 15
16 can rotate in bearing block 15, and division drawstring 17 and detent drawstring 18 have been respectively fixedly connected in regulation handle 16, and division is drawn
17 one end far from regulation handle 16 of rope are fixed on trussed shore 19, and trussed shore 19 is fixed at the center of handsetting gear 6, detent
Drawstring 18 is fixed on sliding block 21 far from one end of regulation handle 16, and sliding block 21 is movably arranged on sliding rail 22, and sliding block 21 can edge
Sliding rail 22 it is mobile, sliding rail 22 is fixed on insulating base 1, is fixedly installed shaft 23 on sliding block 21, living in shaft 23
Dynamic to be provided with pawl 24, sliding block 21 is fixedly installed push rod 25 close to the side of pawl 24, compression is fixedly installed on push rod 25
Spring 26, compressed spring 26 are fixed in the groove of concave block 27 far from one end of push rod 25, and concave block 27 is fixed on cunning
On rail 22.
Preferably as one, driven gear 5 is equal with the radius size of sector gear 9, therefore driven gear 5 and sector
Wheel 9 can be engaged with 10 activity of partial gear.
Preferably as one, multiple guide posts 20 are fixedly installed on insulating base 1,18 activity of detent drawstring is around guiding
Column 20, the effect of guide post 20 are that the wire rope handling direction of detent drawstring 18 is guided and limited.
Working principle: the present apparatus can carry out separating brake and closing operation automatically, specifically, when breaker needs separating brake,
Motor 2 starts and driving worm gear 3 is driven to operate, and driving worm gear 3 drives driving gear 4 to rotate, and it is passive that driving gear 4 drives simultaneously
Gear 5 and handsetting gear 6 rotate, on the one hand, driven gear 5 drives sector gear 9 to rotate by fixing axle 8, although sector
Wheel 9 is movably arranged in fixing axle 8, but because the effect of frictional resistance, sector gear 9 can rotate with, and drive
Partial gear 10 rotates, and on the other hand, handsetting gear 6 drives driving lever 7 to rotate, and realizes sub-switching operation；After separating brake, due to
Partial gear 10 has driven newel post 1 to rotate, so that the plane scroll spring 13 in newel post 2 14 is stretched, therefore
After separating brake, plane scroll spring 13 can restore automatically, so that newel post 1 drives partial gear 10 to reversely rotate, so that
Sector gear 9 also overcomes resistance under the impetus of partial gear 10, rotates around fixing axle 8, restores to original state,
Realize automatic closing, Operation of Electric Systems experience have shown that, the most of failure of overhead transmission line is all " instantaneity ", permanently
Failure be typically less than 10%.Therefore, switch is overlapped automatically, not only increases the safety and reliability of power supply, reduces
Loss of outage, and the transient state for also improving electric system is horizontal, increases the power transmission capacity of high-tension line, can also correct due to
Mistrip caused by switch or protective relaying device.
When carrying out repair and maintenance or electrical component to breaker and damaging, the present apparatus can also manually into
Row divide-shut brake specifically if needing manual brake separating, can rotate clockwise regulation handle 16, on the one hand, regulation handle 16 can pass through
Division drawstring 17 drives trussed shore 19 to rotate, and trussed shore 19 drives handsetting gear 6 to rotate, so that driving lever 7 rotates with it, realization point
Lock, on the other hand, regulation handle 16 can loosen the detent drawstring 18 of winding on it, under the action of compressed spring 26, push away
Bar 25 can be moved inward by sliding block 21 with pawl 24, and ratchet 12 is defined, at this point, since ratchet 12 cannot operate,
So that partial gear 10 can not operate, driven gear 5 and handsetting gear 6 cannot all rotate, and gate-dividing state is locked, can be with
Prevent the automatic closing in repair and maintenance from causing the security risk got an electric shock, if needing closing by hand, reverse operating.
It although an embodiment of the present invention has been shown and described, for the ordinary skill in the art, can be with
A variety of variations, modification, replacement can be carried out to these embodiments without departing from the principles and spirit of the present invention by understanding
