Abstract
The utility model is a tying structural iron core for iron core reactor, consisting of an upper yoke (1), a lower yoke (6), a core column (3), a discus of core column (4), and an air gap insulation, etc. The core column (3) is provided between the end of the upper yoke and the end of the lower yoke; the discus of core column and the air gap insulation are provided in the core column (3); the air gap insulation is also provided between the core column (3) and the discus of core column (5); the air gap insulation is provided between discuses of core column. The upper yoke (2), the lower yoke (6), the core column (3), and a discus of core column (4) adopts the bundle structure that each lamination are bundled via a bundle belt (2), replacing the original structural form that adopts lamination jetting connected via penetrated screw skewer. As a result, the utility model has features of improved local deformed distribution of the magnetic field of the iron core, improved generation of the suspending electric potential, decreased eddy current loss and diffraction loss, increased stacking coefficient of the lamination, improved area of section of the iron core, reduced workload of production, simplified production process, increased material utilization and lowered production cost, etc.
Description
One, technical field
The utility model is the iron core of the binding-type structure used of a kind of iron-core reactor.
Two, background technology
The important feature unshakable in one's determination of iron-core reactor is that iron core is divided into plurality of sections, makes the air gap that forms unshakable in one's determination, produce the diffraction magnetic flux, and the diffraction magnetic flux has comprised very big cross stream component, and it will cause great supplementary load loss in unshakable in one's determination and coil.In order to reduce the diffraction magnetic flux, need total air gap is divided into several small air gaps with discus (stack of lamination).The height of discus is generally 50～100mm, decides on the amount of capacity of reactor.The height of the core limb up and down that links with the iron yoke should be not less than the height of discus.
The air gap of core limb forms by insulation board, becomes discus one by one in order to make lamination, adopts the lamination punching usually, penetrate the core through screw rod structure, the subject matter of this structure exists: after 1, punching unshakable in one's determination adds core through screw rod, having insulation to separate, ten million the core through screw rod floating potential.2, in order to reserve the firm position that the stem discus compresses steel plate and core through screw rod, reduced by 2～3 grades of limit unshakable in one's determination level laminations, reduce space availability ratio, the stack coefficient of lamination reduces, and the close increase of magnetic makes the coil copper material increase, and material cost increases.3, increased core loss after the punching unshakable in one's determination.The stem discus compresses steel plate has increased eddy current loss.4, discus quantity is many, and each of composition discus is opened on silicon steel sheet and all needed punching, and the punching amount is very big, has increased workload.After the silicon steel sheet punching, the location dimension in hole is poor, cause closed assembly unshakable in one's determination after, end face is uneven, presentation quality is poor, diffraction produces loss to be increased.5, because the discus specification is little, cause after its punching, difficult location, positioning accuracy is poor, and technological operation is very dangerous.6, the easy loss of insulation between core through screw rod and the cake unshakable in one's determination produces eddy current.If 7 tiltedly cut after the production line punching with silicon steel sheet and to shear, stock utilization can only reach 50%, causes a large amount of wastes of material.
Three, summary of the invention
For overcoming above-mentioned shortcoming, the purpose of this utility model provides a kind of iron-core reactor binding-type structure iron core, and it can improve the local deformity in magnetic field unshakable in one's determination and distribute, improve the generation of floating potential, can reduce core loss and eddy current loss, improve the stack coefficient of lamination, improve the sectional area of iron core; Reduce the workload when making, production technology is simplified; Improve stock utilization, reduce characteristics such as manufacturing cost.Can satisfy the electric property and the machine-made requirement of iron-core reactor.
The technical scheme that the utility model is taked: on the basis of former iron core, improve core construction, not punching of lamination unshakable in one's determination without core through screw rod, is adopted the colligation form.Be that the utility model is made up of upper yoke, lower yoke, stem, stem discus, air-gap insulation etc.Between the two ends of upper and lower iron yoke stem is housed, is provided with a plurality of stem discuses in the stem, form square shape.Between stem and the stem discus, be provided with air-gap insulation between stem discus and the stem discus; It is characterized in that upper yoke, lower yoke, stem, stem discus are the binding-type structure of its lamination separately by the binding strap colligation, do not need to be the binding-type structure of its lamination separately by the binding strap colligation, do not need on lamination punching and connect by core through screw rod at lower yoke unshakable in one's determination, stem, stem discus.
Because upper yoke of the present utility model, lower yoke, stem, stem discus all adopt the binding-type structure, no longer need punching on lamination, avoided the scale error of punching and reduced layer by layer lamination because the axial uneven degree that the punching position deviation increases, improved the gap precision of stem and stem discus, stem discus and stem discus, improve space availability ratio, reduced eddy current loss and diffraction loss; Saved a large amount of punch work amounts, improved the utilance of material, saved core through screw rod, avoided the floating potential that causes because of core through screw rod, therefore the utlity model has the local deformity that can improve magnetic field unshakable in one's determination distributes, improve the generation of floating potential, reduced eddy current loss and diffraction loss; Improve the stack coefficient of lamination, improved the sectional area of iron core; Reduced the making workload, production technology is simplified, and improves stock utilization, reduces characteristics such as manufacturing cost.
Four, description of drawings
Accompanying drawing is the utility model schematic diagram.
Five, specific implementation method
As shown in drawings, the utility model is made up of upper yoke (1), lower yoke (6), stem (3), stem discus (4), air-gap insulation (5) etc., stem (3) is housed between the two ends of last lower yoke (1), (6), be provided with stem discus (4) in the stem (3), form square shape, be provided with air-gap insulation (5) between stem (3) and stem discus (4), stem discus (4) and stem discus (4), upper yoke (1), lower yoke (6), stem (3), stem discus (4) are the binding-type structure of its lamination separately by binding strap (2) colligation.
Because binding-type structure of the present utility model has replaced former punching on lamination, has used the version of the fastening connection of core through screw rod then, need punching on lamination.Therefore the utlity model has the local deformity that can improve magnetic field unshakable in one's determination distributes, improve the generation of floating potential, eddy current loss and diffraction loss have been reduced, improved the stack coefficient of lamination, improved the sectional area of iron core, reduced the making workload, production technology is simplified, improve stock utilization, reduced characteristics such as production cost.
