Description
Technical field
The utility model relates to the operating mechanism technical field, specifically a kind ofly is applied on the HVAC vacuum circuit breaker, for the divide-shut brake of circuit breaker and cut-off fault current and provide the double suction of power to close face unicoil Monostable permanent magnetic mechanism.
Background technology
Operating mechanism in middle pressure power transmission and distribution product by its working method branch, has spring energy agency, and electromagnetic mechanism also has permanent magnet mechanism.Permanent magnet mechanism is simple in structure because of it, and part is few, and high reliability features has obtained increasing application in middle pressure power transmission and distribution product, presses one of main flow mechanism of power transmission and distribution product in becoming.The version of permanent magnet mechanism has: bistable state two coil configuration, monostable two coil configuration, monostable single coil structure.The monostable permanent magnet mechanism of unicoil is planted structure with the first two and is compared, and it is little and compact to have size, and action stability is higher, the advantage that cost is lower; But it also has action stability mechanical property relatively poor, that follow vacuum circuit-breaker to mate reasonable inadequately and the shortcoming that branch refuses to close phenomenon occurs refusing.And the first two is planted structure and the situation that mechanism is parked in intermediateness can occur, cause refusing branch or refuse to close, and leakage field is more, and the permanent magnet magnetic force utilization ratio is low.
Summary of the invention
The purpose of the utility model is the deficiency that overcomes prior art; The unicoil Monostable permanent magnetic mechanism that provides a kind of double suction to close face; Promoted the action stability of permanent magnet mechanism, made its mechanical property of following vacuum circuit-breaker coupling more reasonable, and effectively stop to refuse the appearance that branch refuses to close phenomenon.
In order to achieve the above object; The utility model has designed a kind of double suction and has closed face unicoil Monostable permanent magnetic mechanism, comprises separating brake end cap, magnetism isolating spacer piece, moving iron core, magnetic guiding loop, permanent magnet, coil, shell, quiet end cap and drive rod, and it is characterized in that: the two ends of said shell are assembled separating brake end cap, quiet end cap respectively; Said quiet end cap is the notch cuttype structure; Coil is assemblied in the outer ring of notch cuttype structure flange, coil top assembling permanent magnet, the inner ring assembling magnetic guiding loop of permanent magnet; Said magnetism isolating spacer is packaged to be fitted between permanent magnet, magnetic guiding loop and the separating brake end cap; Said moving iron core is assemblied in the top of notch cuttype structure flange, and the section of moving iron core be the structure of falling the T-shape, the assembling that matches with shell, coil, magnetic guiding loop, magnetism isolating spacer piece of this structure of falling the T-shape, and form two adhesive faces; Pilot hole and activity that said drive rod passes quiet end cap, moving iron core and separating brake end cap center respectively are assemblied between separating brake end cap and the quiet end cap.
Described two adhesive faces are respectively the first adhesive face of moving iron core and magnetic guiding loop adhesive formation, and the second adhesive face of moving iron core and quiet end cap adhesive formation.
The utility model is compared with prior art, has following advantage:
1. accomplish separating brake, closing operation by single coil, compact conformation, size is little, and cost is low, has also avoided the moving iron core of two coil configuration to be parked in the centre position simultaneously and has caused occurring refusing to close the fault of refusing branch;
2. have two adhesive faces, guaranteed leakage field still less, the permanent magnet magnetic force utilization ratio is high, and it is bigger that combined floodgate is managed power, can satisfy the requirement of big capacity switch;
3. double suction closes face when separating brake, and two adhesive faces separate simultaneously, thereby the opening velocity when making manual brake separating is faster, the switch interrupting performance when having guaranteed manual brake separating.
Description of drawings
Combine accompanying drawing that the utility model is described further at present.
Fig. 1 is the structural representation of the utility model.
Referring to Fig. 1,1 is the separating brake end cap; 2 is the magnetism isolating spacer piece; 3 are moving iron core; 4 is magnetic guiding loop; 5 is permanent magnet; 6 is coil; 7 is shell; 8 is quiet end cap; 9 is drive rod.
