Description
Technical field
The utility model belongs to the technical field of electric appliances that is applied to the outdoor high-voltage vacuum switch fitting, particularly relates to the operating mechanism of switch.
Background technology
The outdoor high-voltage vacuum switch is a vitals on the high-tension line, for it the working stability situation especially the operating mechanism unfailing performance of these parts become insider's question of common concern.In the last few years; This novel operating mechanism that is applied to the high-pressure vacuum switch field of permanent-magnet manipulating mechanism, high with its dependable performance stability, breaking speed is quick; Advantage such as non-maintaining has caused insider's common concern during application; And obtained development rapidly, especially indoors application is quite wide in the vacuum circuit-breaker, and the synchronism in the outdoor permanent magnetism vacuum circuit-breaker is the problem that a lot of manufacturers can't resolve always.
Synchronism in the prior art in the outdoor permanent magnetism vacuum circuit-breaker, the uncontrollable problem of the synchronism of various degrees always.Switch main body needs locker to remain on closing position reliably, and parts are many, complex structure, and security reliability is low.Needing badly in the prior art will provide a kind of actuating performance and outdoor vacuum switch to cut-off required characteristic to coincide, and breaking speed is fast, a kind of external sluice separating spring Monostable permanent magnetism operating mechanism of safety and reliability.
Summary of the invention
The utility model purpose is to provide a kind of actuating performance and outdoor vacuum switch to cut-off required characteristic to coincide, and breaking speed is fast, a kind of external sluice separating spring Monostable permanent magnetism operating mechanism of safety and reliability.In order to realize above purpose; The utility model has adopted following technical scheme: a kind of external sluice separating spring Monostable permanent magnetism operating mechanism; It is characterized in that: comprise outer yoke cover, coil, permanent magnetic material, inner yoke, Aluminum cover, upper magnet yoke cover plate, moving armature, moving armature pull bar, lower yoke cover plate, sluice separating spring; Described coil is positioned at the inside of outer yoke cover, between upper magnet yoke cover plate and the lower yoke cover plate; Described permanent magnetic material is between inner yoke and outer yoke cover and strong bond; The following adhesive plane that described upper magnet yoke cover plate lower surface is a toroidal cooperates with the last adhesive flat shape of moving armature, and the position is corresponding; Described moving armature, moving armature pull bar connect through threaded engagement, and install with one heart, and moving armature axial motion between Aluminum cover and upper magnet yoke cover plate; Described sluice separating spring be positioned at the lower yoke cover plate the bottom and with the coaxial installation of moving armature pull bar.
Described moving armature is shaped as cylinder, and between the inner headed face of moving armature and inner yoke the magnetic flux air gap is set.
Through above-mentioned design; The utility model can bring following beneficial effect: this programme is mainly used in the workplace (being that three Switch main bodies need three operating mechanisms) of an operating mechanism of individual event Switch main body adapted; Because its sluice separating spring is external, can adjust mechanism's branch, closing time.Based on this characteristic, can split close close, the separating brake control same period.The external uncontrollable problem of synchronism that solved of sluice separating spring, three individual drive have been saved 95% power drive mechanism spare simultaneously.Reliability has had the lifting of bigger meaning.The moving armature pull bar is taked non-magnet material.Can make mechanism obtain just to have divided faster and firm sum velocity.Aluminum cover adopts non-magnet material to make, and is concentric with the outer yoke cover, circle in cylindrical interference fit and the outer yoke cover.The center is provided with through hole and moving armature pull bar matched in clearance.Its actuating performance of operating mechanism of design and outdoor high-voltage vacuum switch desirable characteristics coincide like this, and simple in structure, parts are few, and are safe and reliable, and its monostable structure can make Switch main body need not locker and remain on closing position reliably.
Description of drawings
Below in conjunction with accompanying drawing and embodiment the utility model is further described:
Fig. 1 is the structural representation of the utility model.
Wherein 1 is that outer yoke cover, 2 is that coil, 3 is that permanent magnetic material, 4 is that inner yoke, 5 is that Aluminum cover, 6 is that upper magnet yoke cover plate, 7 is that moving armature, 8 is that moving armature pull bar, 9 is that lower yoke cover plate, 10 is a sluice separating spring.
Embodiment
As shown in Figure 1; A kind of external sluice separating spring Monostable permanent magnetism operating mechanism; By permanent magnetic material (neodymium iron boron) 3 the permanent-magnetic field source is provided, produces transient electromagnetic field and permanent magnetic field stack, follow the compression and the recovery of sluice separating spring 10 simultaneously by external circuit control magnet exciting coil 2; The vector of magnetic field force and spring force and effect under, drive the moving armature motion and accomplish close, the work conversion of separating brake position; It is characterized in that: permanent magnetic material (neodymium iron boron) 3 is also bonding firm between inner yoke 4 and outer yoke cover 1; It is concentric also through threaded engagement with moving armature pull bar 8 positions to be shaped as cylindrical moving armature 7, moves between Aluminum cover 5 and upper magnet yoke cover plate 6; Below the upper magnet yoke cover plate 6 toroidals with circular above the moving armature 7 be the adhesive plane; Wherein, below the said upper magnet yoke cover plate 6 toroidals axially with moving armature 7 on the position shape on adhesive plane corresponding; Magnetic flux air gap Lg is set between the inner headed face of moving armature 7 and inner yoke 4; When moving armature 7 is in the combined floodgate terminal location, main flux is through permanent magnetic material (neodymium iron boron) 3, inner yoke 4, magnetic flux air gap, moving armature 7, upper magnet yoke cover plate 6, outer yoke cover 1 and the closed combined floodgate stable state that constitutes this mechanism keeps the permanent magnetism road; When moving armature 7 was in the separating brake position, moving armature 7 closed with Aluminum cover 5 tight bats under the effect of sluice separating spring 10.And remain on the separating brake terminal location.The separating brake of this mechanism keeps only depending on sluice separating spring 10 independent completion.
The sluice separating spring 10 external uncontrollable problems of synchronism that solved, three individual drive have been saved 95% power drive mechanism spare simultaneously.Reliability has had the lifting of bigger meaning.Moving armature 7 pull bars are taked non-magnet material.Can make mechanism obtain just to have divided faster and firm sum velocity.Aluminum cover 5 adopts non-magnet materials to make, with outer yoke overlap 1 concentric, round in cylindrical interference fit and the outer yoke cover 1.The center is provided with through hole and moving armature pull bar 8 matched in clearance.
