Abstract
The utility model relates to a novel control mechanism for an indoor high voltage vacuum circuit breaker, which is composed of an energy storage motor in a power part, an energy storage spring, an assembling framework, a transmission mechanism for a double-pole four connecting rod, and an interlocking mechanism, wherein the transmission mechanism part is composed of a worm gear and worm screw transmission mechanism, a chain wheel speed reducing mechanism, an energy storage mechanism mainly driven by a cam, an energy storage keeping mechanism and a switching-on tripping mechanism. In addition, the energy of the worm gear and worm screw transmission mechanism is mutually stored by a motor speed reducing mechanism. The utility model makes a unilateral bearing meet the performance requirements and reduce the noise. The utility model is combined the main body of the circuit breaker into a whole body, so the match performance of the whole body is easily guaranteed, and the utility model has the advantages of high reliability, and reasonable, novel and simple integral structure.
Description
The utility model relates to a kind of indoor high-voltage vacuum circuit breaker operating mechanism.
Domestic existing operating mechanism is being to adopt two body ways of connecting with cooperating of breaker body, it is difficult to guarantee its overall performance, the adjustment difficulty is very big, the online part of the mechanism five bar linkage structure forms that adopt more, but increased unreliable factor, also there is a pair of above click of use in existing mechanism as transmission mechanism, and this kind mechanism noise is bigger.
The purpose of this utility model is the defective at above-mentioned existence, proposes a kind of new indoor high-voltage vacuum circuit breaker operating mechanism.
Technical solution of the present utility model:
Energy storage motor 1, energy-stored spring 2, assembling skeleton and secondary four jointed gear units 21,23 and the latching device 9 that comprise power section are formed, transmission mechanism partly is the worm gear by the manual energy storage of motor decelerating mechanism---worm gearing, sprocket wheel reducing gear, based on the stored energy mechanism of cam drive, energy storage maintaining body and combined floodgate tripping mechanism are partly formed.
Manually the energy storage worm gear---the worm gear 6 in the worm gearing is to be installed on the sprocket wheel 3 by unilateral bearing 4, can only the unidirectional delivery moment of torsion between worm gear 6 and the sprocket wheel 3.
Stored energy mechanism comprises that mainly sprocket wheel 3, chain 8, sprocket wheel 12, wheel 13, energy storage keep sincere sub 9, cam 20 and energy-stored spring 2 to form, its middle sprocket 3 is to be installed on the motor output shaft by a unilateral bearing 5, can only the unidirectional delivery moment of torsion between motor shaft and the sprocket wheel 3; Sprocket wheel 12 is installed on the energy storage axle by single-row radial ball bearing, and it dallies with respect to the energy storage axle.
On along the circumferential direction equally distributed two backing pins 15, the wheel 13 slide block 14 is installed on the sprocket wheel 12, sprocket wheel 12 is by backing pin 15, slide block 14 fifth wheels 13).
Middle locking mechanism in the stored energy mechanism is by sincere sub 9, backing pin 10, and travel switch 17 is formed.
Switching-on mechanism is made up of sincere sub 9, cam drive and the two poles of the earth four jointed gear units 21,23.
Advantage of the present utility model:
Most of part all adopts sheet stamping member, and machine components are easy to processing, and material is not had specific (special) requirements; Cabinet is separated into four assembly spaces by three central dividing plates, and all parts of operating mechanism are installed in the cabinet; Adopted worm gear---worm gearing, sprocket wheel reducing gear, cam drive, four jointed gear units; Adopt unilateral bearing unidirectional delivery moment of torsion, reduced energy consumption and noise, make this circuit breaker actuating mechanical structure novelty, reasonable, stable performance, Mechanical Reliability height.
Accompanying drawing 1 is the assembling schematic diagram of drive connection.Among the figure 7 is worm screws.
Accompanying drawing 2 is assembling schematic diagrames of steering position relation.
Provide operation principle of the present utility model below in conjunction with accompanying drawing: during energy storage, at first start energy storage motor 1, through sprocket wheel 3, chain 8, the sprocket wheel reducing gear of sprocket wheel 12, its middle sprocket 3 is installed on energy storage motor and the output shaft by unilateral bearing 5, makes 3 on motor output shaft and the sprocket wheel can only the unidirectional delivery moment of torsion; Sprocket wheel 12 is installed on the energy storage axle by a single-row radial ball bearing 11, makes it to dally on the energy storage axle, again by the slide block 14 on the backing pin 15 on the sprocket wheel 12, the wheel 13, promotes the energy storage axle and rotates, thereby make spring energy-storage.When spring energy-storage was about to put in place, pin 16 drove bent plate 17 rotations by bent plate 19 on the cam 20, presses travel switch 18 to cut off the power supply of energy storage motor 1; Backing pin 16 is pressed into slide block 14 in the wheel 13 simultaneously, makes clutch between sprocket wheel 8 and the wheel 13; When energy storage put in place, the machinery of energy storage kept blocking the backing pin 10 on the wheel 13 by sincere sub 9, and the energy of energy-stored spring is maintained.
Keep balance in case broken when energy storage, promptly work as sincere sub 9 and be open, the energy storage axle will rotate under the effect of spring energy, by cam drive, the two poles of the earth quadric chain 21,23, finally make breaker closing.After combined floodgate put in place, closing position was maintained it by tripping mechanism 22.When needing separating brake, only need clockwise rotate latching device, can make closes a floodgate keeps losing support, and at this moment circuit breaker will be finished the separating brake action under the effect of tripping spring 24 and contact pressure spring.
