Description
Technical field
The utility model relates to power equipment, particularly relates to a kind of permanent-magnet operating mechanism.
Background technology
Along with science and technology development and society progress, to the stability of electric power system and the requirement of automaticity more and more higher, circuit breaker, as electric equipment very important in electric power system, receives much concern always.Vacuum circuit-breaker, because of its high reliability, high stability, non-maintaining, life-span long feature, remains leading status in field of switches for many years all the time.Due to the basic function of circuit breaker be embodied in contact point, close in action, and point, close action be realized by the permanent-magnet operating mechanism in circuit breaker, therefore the service behaviour of permanent-magnet operating mechanism and the quality of quality, plays an important role to the service behaviour of vacuum circuit-breaker and reliability.Spring permanent-magnet operating mechanism parts are many, make action loaded down with trivial details thus cause reliability well to be ensured, the safe and stable operation tool of operating mechanism to electric power system therefore studying high reliability is of great significance.
Summary of the invention
In order to overcome the deficiency of above-mentioned existing equipment, the utility model provides that a kind of moving component is few, structure is simple, transmission is simple, and reliability is greatly enhanced and achieves the permanent-magnet operating mechanism of non-maintaining requirement.
To achieve these goals, the technical solution adopted in the utility model is:
A kind of permanent-magnet operating mechanism, comprise permanent magnet, described permanent magnet upper end devises afterbody tripping spring, the left fixed head that described permanent magnet is arranged by the left and right sides and right fixed head are fixed, described left fixed head and right fixed head are connected by supporting linkage and fix, described permanent magnet lower end is connected with kinematic link, and two ends, described kinematic link left and right are each hinged with one end of 2 length of a film short axial links, and the other end and the transmission main shaft of described major and minor axis connecting rod are hinged.
As the further improvement of such scheme, described permanent magnet lower end is provided with axle connected device, and described axle connected device is connected with kinematic link.
As the further improvement of such scheme, it is spacing that described permanent magnet is provided with tripping spring catch at afterbody separating brake spring end.
As the further improvement of such scheme, described left fixed head and right fixed head lower end are equipped with two draw-in grooves, and it is outer and be fastened in draw-in groove that left fixed head and right fixed head are stretched out in described kinematic link and transmission main shaft two ends.
As the further improvement of such scheme, described supporting linkage is provided with divide-shut brake direction board.
The beneficial effects of the utility model:
A kind of permanent-magnet operating mechanism of the utility model, structurally have simplification greatly, the amount of parts used is only 35% ~ 40% of spring operating mechanism, so weight is lighter, more convenient operation, reliable in action.At closing position, dynamic iron core is remained on closing position by the low magnetoimpedance passage that the permanent magnet of operating mechanism utilizes dynamic and static iron core to provide; At open position, kept by tripping spring, therefore machine driving is simple in the extreme, vacuum arc-extinguishing chamber contact stable movement during divide-shut brake, without refusing to close, refuse point and close, miss point phenomenon by mistake, substantially increases the reliability of vacuum circuit-breaker.
Accompanying drawing explanation
Fig. 1 is the utility model preferred embodiment structural representation.
Fig. 2 is that the utility model preferred embodiment permanent magnet and left and right fixed head assemble schematic diagram.
Fig. 3 is the utility model preferred embodiment transmission component assembling schematic diagram.
Fig. 4 is the utility model preferred embodiment permanent magnet assembling schematic diagram.
Embodiment
Below in conjunction with accompanying drawing and preferred embodiment of the present utility model, the utility model is described further:
Referring to figs. 1 through Fig. 4, a kind of permanent-magnet operating mechanism, comprises permanent magnet, and described permanent magnet 3 upper end devises afterbody tripping spring 2, and it is spacing that described permanent magnet 3 is provided with tripping spring catch 1 at afterbody tripping spring 2 end.
The left fixed head 41 that described permanent magnet 3 is arranged by the left and right sides and right fixed head 42 are fixed, described left fixed head 41 and right fixed head 42 are connected by supporting linkage 11 and fix, described supporting linkage 11 is provided with divide-shut brake direction board 9, plays the function of the state of instruction permanent magnet mechanism action on/off switch.
Described permanent magnet 3 lower end is provided with axle connected device 5, and described axle connected device 5 is connected with kinematic link 6, and described kinematic link about 6 two ends are each hinged with one end of 2 length of a film short axial links 7, and the other end and the transmission main shaft 8 of described major and minor axis connecting rod 7 are hinged.Described left fixed head 41 and right fixed head 42 lower end are equipped with two draw-in grooves, described kinematic link 6 and transmission main shaft 8 two ends stretch out left fixed head 41 and right fixed head 42 outer and be fastened in draw-in groove.
During combined floodgate, when the permanent magnetism axle in permanent magnet 3 moves downward, the axle connected device 5 be attached thereto moves down, drives kinematic link 6 to rotate, and major and minor axis connecting rod 7 is subject to a downward thrust and also moves thereupon, and transmission main shaft advance the puck is closed a floodgate.During separating brake, when the permanent magnetism in permanent magnet 3 axially moves, the axle connected device 5 be attached thereto moves upward, and drive kinematic link 6 to rotate, major and minor axis connecting rod 7 is subject to a pulling force upwards and also moves upward, and transmission main shaft is moved backwards and carries out separating brake.The amount of parts that this product uses reduces many than spring operating mechanism structure, and designs simplification is many, and machine driving is simple, improves the reliability of motion.
More than that preferred embodiment 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.
