Description
Technical field
The present invention relates to transformer technology field, be specifically related to the manufacture method of a kind of transformer core and transformator.
Background technology
Transformator be the principle utilizing electromagnetic induction to change the device of alternating voltage, main member includes coil and ferrum
Core, iron core includes iron core body and the assembly of clamping iron core body.Iron core body is formed by stacked before and after lamination, intermediate portion
Demultiplexing is in suit coil, and this part is also referred to as iron core column.Its top and bottom are also referred to as iron yoke for closed magnetic circuit, and iron yoke is divided into
Upper yoke and lower yoke.Iron core is the basic element of character of transformator, and Main Function is to provide magnetic circuit, makes simultaneously as mounting framework
With.The magnetic conductor of iron core is the magnetic circuit of transformator, and it transfers magnetic energy to the electric energy of primary circuit, is changed into by the magnetic energy of oneself again
The electric energy of secondary circuit, is the medium of energy conversion.Therefore, iron core is significant for transformator.
The manufacture process of transformator it is generally required to iron core body is carried out closed assembly, mounting coil in iron core column and use
Iron core body is clamped fixing by clamping device.If iron core body can not effectively clamp, lamination will be at alternation magnetic
Under field action, there is minor variations i.e. magnetostriction, thus produce noise.If coil and iron core body directly assemble loosely
Gu, then noise can be increased.Further, since upper yoke is deposited in above iron core column, the height of stacking is wayward, causes thus producing
The stress of raw lamination is wayward.
Existing iron core body typically has two kinds of structures.The first, as it is shown in figure 1, iron core body 10 structure for being positioned on
The E shape iron core block 11 of lower section is to inserting structure.Due to structure problem, this structure is the most insecure with the assembling of coil, causes change
During depressor work, coil is loose, produces noise.The second, as in figure 2 it is shown, iron core body 10 includes the upper ferrum being cuboid
Yoke block 12 and lower yoke block 14 and iron core column block 13.Wherein, upper yoke block 12 is horizontally disposed, lower yoke block 14 and upper yoke block
The length of 12 is identical and is parallel to below upper yoke block 12, and iron core column block 13 is vertically connected on upper yoke block 12 and lower yoke block 14
Between.This structure disadvantageously, upper yoke block 12 is deposited in 13 pieces of tops of iron core column, the height of stacking is wayward, leads
The stress causing consequent lamination is wayward, is easily generated noise.
Generally speaking, in prior art, there is many problems in transformator.During transformer manufacturing, due to the knot of iron core body
Structure problem, iron core body can not effectively be clamped, and the assembling with coil is insecure.Transformator easily produces noise and unloaded electricity
Stream is big.Further, since the size and shape problem of iron core block, when making the material of iron core block, there are substantial amounts of leftover pieces, these
Corner considerably increases the manufacturing cost of iron core.
Summary of the invention
The present invention is directed to existing technical problem make improvements, i.e. the technical problem to be solved is to provide one
Transformer core, the upper yoke part of this iron core breaks the whole up into parts, and advantageously reduces the manufacturing cost of transformer core, it is simple to iron core
The assembling of body and clamping.
For solving the problems referred to above, the technical scheme that the present invention provides is:
A kind of transformer core, including iron core body and the assembly of clamping iron core body, described iron core body includes being
