Abstract
The utility model relates to a dry type transformer with an annular iron core. The utility model is formed by combining the iron core, a framework and a coil. The iron core is composed of at least two O-shaped encircled frame bodies, and each O-shaped encircled frame body is formed by continuously encircling magnetism conducting belt material with different widths according to the order that wide belt material is encircled after encircling narrow belt material or the narrow belt material is encircled after encircling the wide belt material, and the magnetism conducting belt material is equal or unequal in length. After the two O-shaped encircled frame bodies with the same size are tightly attached by a frame body, a single-phase shell type encircled iron core can be combined; after the other large O-shaped encircled frame body is sheathed on the outside of the single-phase shell type encircled iron core, a three-core column three-phase encircled iron core is combined.
Description
The utility model relates to a kind of transformer, relates to a kind of ring structure iron core dry-type transformer or rather.
Dry-type transformer mainly is made up of iron core and coil, and the iron core of existing dry-type transformer is a lamination, promptly adopts the lamination mode that the stem stem silicon steel sheet of plurality of specifications or the iron yoke silicon steel sheet stack of plurality of specifications are constituted.By the iron core of stack moulding, all there is inevitable slit in the edge joint place of every lamination and causes the increase of magnetic resistance and iron loss.In addition, the magnetization capacity of seam causes the increase of transformer magnetizing current again, has reduced power factor, has increased reactive power consumption, has had a strong impact on the power supply quality of electrical network.Noise when the existence of transformer seam has also caused operation, index cause serious environmental to pollute up to the 45-70 decibel, and particularly at the dry-type transformer of indoor operation, its noise also has a strong impact on people health.
The purpose of this utility model is a kind of ring structure iron core dry-type transformer of design, with the seam problem of thorough solution laminated core structure dry-type transformer.
Ring structure iron core dry-type transformer of the present utility model by iron core, be set in the skeleton on the iron core stem stem and the coil that is wrapped on the skeleton constitutes, is characterized in that:
Described iron core is constituted around framework by at least two O types; Described O type is to be made of by the wide or earlier wide narrow order continued circling in back in earlier narrow back magnetic conducting band material isometric or not isometric and that width is different around framework, and the O type becomes the stepped profile semicircle around the cross section of framework stem stem.
Described iron core is around framework by two onesize O types, fit tightly the single-phase shell-type wound core of composition with an edge, outer edge stem stem cross section becomes the stepped profile semicircle, and edge SMIS cross section is the stepped profile circle that is formed by two identical stepped profile semicircle butt joints of diameter in the sticking part.
Described iron core is nested with the single-phase core type ring formed on around framework at a little O type around iron core by a big O type around the framework driving fit, and edge stem stem cross section is two stepped profile circles that the identical stepped profile semicircles butt joint of diameter forms.
Described skeleton is the cylinder that is made of two semicircle cylindrical shell butt joints.
Described iron core does not have the seam slit, and iron core column is opening not.
The O type new with this practicality is basic building block around framework, after combination and special process processing, again with electromagnetic wire respectively around last transformer required elementary, secondary coil, just can produce three-phase three stem stem wound core dry-type transformers.
Further specify technology of the present utility model below in conjunction with example and accompanying drawing.

Referring to Fig. 3, Fig. 4, the thick 0.5mm-0.22mm of becoming permeability magnetic material (comprising silicon steel sheet) with whole volume, on its slitter line, be processed into the band material (the wide variation of band material is more little, and ladder is crossed and getted over slyness, and the O type is got over approximate half-circular or circle around the framework cross section) that width did not wait and became stepped variation.Become O type around framework by the first wide order in narrow back with the continuous lap wound of annular solid with the magnetic conducting band material that processes, shown among Fig. 32, its A-A to cross-section structure as shown in Figure 4, edge stem stem cross section is two interior convex ladder semicircles.In the ladder semicircle each is near false to be that band material lap wound by a kind of width constitutes like rectangle.
Referring to Fig. 3, Fig. 6, two onesize O type frameworks 2 are closely combined two O type wound cores with an edge, as shown in Figure 5, its A-A to cross-section structure as shown in Figure 5, edge SMIS post cross section is a Step Circular in the sticking part, be made of the semicircle butt joint of two ladders, outer edge stem stem cross section is still two interior convex ladder semicircles.In like manner, among the figure each in Step Circular or the ladder semicircle approximate rectangular all be that band material lap wound by a kind of width constitutes.
Referring to Fig. 7,8, outside Fig. 5, two O type wound cores of 6, form a big O type around framework 3 with the magnetic conducting band material that processes by the narrow continuous lap wound of order in earlier wide back again, as shown in Figure 5, the big O type of formation closely is nested with the core structure of the little O type of two identical sizes around framework 2 around framework, its A-A to cross-section structure as shown in Figure 8, its outer edge stem stem cross section and in edge SMIS post cross section be Step Circular, constitute by the semicircle butt joint of two ladders.In like manner, among the figure each in the Step Circular approximate rectangular also all be that band material lap wound by a kind of width constitutes.
Among Fig. 11 is with the ring structure iron core dry-type transformer coil of electromagnetic wire on the ring structure iron core post.
Ring iron core dry type transformer is compared with traditional laminated core structure dry-type transformer has following advantage:
1, the energy-conservation 30-40% of own loss, no-load current decline 80-90%;
2, noise objective is lower than 40 decibels;
3, iron core does not have seam magnetization capacity, has improved the power factor of transformer, has reduced reactive loss, has improved
The power supply quality of electrical network;
4, raw material have descended about 20%, have reduced manufacturing cost;
5, the volume of transformer and weight have significantly decline;
6, wound core machine-shaping machineryization, production efficiency improve 5-8 doubly;
7, iron core adopts and need not clamping device around mode, has avoided the loss that brings because of the clamping force of iron core;
8, the ring-like coiling of iron core, the ultrathin permeability magnetic material manufacturing of very suitable employing can be given full play to ultrathin permeability magnetic material
Good characteristic of magnetization, improve the performance level of transformer, laminated core structure then can't utilize this characteristic.
