The beneficial effects of the utility model:
This Monostable permanent magnetic mechanism only needs one just can realize grasping empty circuit breaker ABC three-phase combination separating brake simultaneously, the transform linear motion of permanent magnet mechanism moved end is the rotation of output toggle arm by the mode adopting plane tangent mechanism, rotated by drive rod and crank handle turns breaker main shaft, connecting lever on main shaft drives insulated tension pole motion, insulated tension pole drives the connecting lever motion on terminal post enclosed in arc extinguish chamber, and then drive breaker vacuum arc control device contact to carry out on/off switch motion, abandon the structure that traditional ABC three-phase separate is vertical, eliminate the otherness that three mechanisms move simultaneously, only need during assembling to regulate the length of insulated tension pole just can obtain desirable mechanical property parameter, substantially increase production efficiency, improve properties of product.
Further, this mechanism is also provided with manual brake separating link, and by the optimization of gearratio, the operating physical force that mechanism manual is threaded off reduces greatly, and tripping spring in turn ensure that enough opening velocities simultaneously, achieves manual brake separating truly.This patent product construction output characteristic and vacuum switch no-float, be applicable to 12kV vacuum switchgear and use very much.
Further, when repeatedly closing a floodgate can there is flexible deformation in output shaft, described organization establishes moved end guidance system 3 and quiet end guidance system 11, the load stress of balanced output shaft and ensure that set life-span of output shaft, reduce load stress to affect the flexible deformation of output shaft, ensure that the life-span of mechanism.
Accompanying drawing explanation
Structural representation when Fig. 1 is the utility model preferred embodiment separating brake.
Embodiment
Below in conjunction with accompanying drawing, the utility model is described further:
With reference to Fig. 1, described mechanism comprises connecting rod 2, output shaft 4, output toggle arm 5, drive rod 6, permanent magnet mechanism moved end 10 and the quiet end 8 of permanent magnet mechanism, the quiet end 8 of described permanent magnet mechanism is built with divide-shut brake coil and permanent magnet, described permanent magnet mechanism moved end 10 is rigidly connected by the screw thread on mandrel and output shaft 4 one end, described output shaft 4 is connected by mandrel thread with permanent magnet mechanism moved end 10, described output shaft 4 one end and output toggle arm 5 one end hinged, described connecting rod 2 is provided with chute, described output toggle arm 5 is hinged with drive rod 6 after passing the chute on connecting rod 2 by slide bar, output toggle arm 5 can move in chute, described permanent magnet mechanism is provided with a manual brake separating axle 1, connecting lever on described connecting rod 2 other end and manual brake separating axle 1 is hinged, described drive rod 6 other end and crank 9 hinged, breaker main shaft 12 is provided with in described crank 9.Described mechanism is also provided with moved end guidance system 11 and quiet end guidance system 3.Described guidance system 11 and 3 is all rigidly connected by guideway, the clamping plate of fixed guide axle sleeve and the column of strap and forms.The other end of described output shaft 4 is arranged in the guideway of quiet end guidance system 3, output shaft 4 can in axial motion, described permanent magnet mechanism moved end 10 is rigidly connected with guide rod, described permanent magnet mechanism moved end 10 guide rod is arranged in the guideway of moved end guidance system 11, permanent magnet mechanism moved end 10 can in axial motion, on described breaker main shaft 12, cover has three main shaft connecting levers 13 to drive the insulated tension pole 14 of ABC three-phase and connecting lever 17 to move respectively, realizes circuit breaker three-phase and moves simultaneously.
The motion mode of mechanism:
Close a floodgate and move: during combined floodgate, pass to forward current to mechanism's divide-shut brake coil, current induced magnetic field, permanent magnet mechanism moved end 10 is close to permanent magnet mechanism quiet end 8 with certain speed under the influence of a magnetic field, drive output shaft 4 to left movement, permanent magnet mechanism moved end 10 driver output axle 4 drives output toggle arm 5 to turn clockwise simultaneously, under the effect of drive rod 6 and crank 9, breaker main shaft 12 is rotated counterclockwise, three connecting levers 13 on breaker main shaft 12 drive insulated tension pole 14 and connecting lever 17 to move, connecting lever 17 is connected with arc control device moving contact by bearing pin, realize the combined floodgate of three arc control device.After combined floodgate puts in place, under the effect of magnetic field of permanent magnet, permanent magnet mechanism moved end 10 and the firmly adhesive of the quiet end 8 of permanent magnet mechanism, remain on closing position.The process of closing a floodgate is electromagnetic force combined floodgate, permanent magnetic keeps, and gives tripping spring 16 energy storage when mechanism closes a floodgate by the connecting lever 7 on breaker main shaft 12.
Separating brake moves: pass to electric current in the other direction to actuator coil during separating brake, the magnetic field that the field weakening permanent magnet that electric current produces produces, make the confining force of mechanism's permanent magnet be not enough to resist the pulling force of tripping spring 16, under the pulling force effect of tripping spring 16 permanent magnet mechanism moved end 10 with certain speed away from the separating brake action until separating brake has put in place of the quiet end 8 of permanent magnet mechanism.Separating brake process removes snap close by electromagnetic force, drives separating brake completely, therefore have good speed characteristics by tripping spring 16.
This permanent magnet mechanism further provided with manual breaking function.Under "on" position, owing to there is the pulling force of contact counter-force and tripping spring 16, mechanism is ready at all times separating brake, but the confining force due to permanent magnet generation overcomes system counter-force and makes again mechanism firmly remain on closing position, can make mechanism's separating brake as long as therefore reduce confining force or add Iarge-scale system counter-force.Manual brake separating axle 1 is driven to rotate counterclockwise by the connecting lever on rotation manual separating brake axle 1 during manual brake separating, under the transmission of connecting rod 2, output toggle arm 5 and output shaft 4, system counter-force continues to increase, until system counter-force is greater than the closing retention force of permanent magnet mechanism and removes switch-on latching, under the drive of tripping spring 16 permanent magnet mechanism moved end 10 with certain speed away from the quiet end 8 of permanent magnet mechanism, the separating brake action until separating brake has put in place.Because manual brake separating link gearratio is higher, manual brake separating operating physical force is very little, and meanwhile, tripping spring 16 drives separating brake in turn ensure that opening velocity, makes manual breaking function be able to real realization.
When considering that mechanism closes a floodgate, comparatively large and mechanism's output shaft 4 stress point of load is away from the strong point, when repeatedly closing a floodgate can there is flexible deformation in output shaft, for the load stress of balanced output shaft 4 and the set life-span of guarantee output shaft 4, be provided with quiet end guidance system 3 and moved end guidance system 11 respectively at mechanism two ends.What play the guiding role is middle brass axle sleeve, axle sleeve limits the motion of output shaft 4 and permanent magnet mechanism moved end 10, make permanent magnet mechanism moved end 10 and output shaft 4 remain at axial motion, reducing load stress affects the flexible deformation of output shaft 4, ensure that the life-span of mechanism.
More than that better enforcement of the present utility model is illustrated, but the utility model is created and is not limited to described embodiment, those of ordinary skill in the art also can make all equivalent modifications or replacement under the prerequisite without prejudice to the utility model spirit, and these equivalent modification or replacement are all included in the application's claim limited range.
