Description
Technical field
This utility model is related to transformer technology field, and in particular to a kind of transformer core.
Background technology
Transformator is that main member includes coil and ferrum changing the device of alternating voltage using the principle of electromagnetic induction
Core, iron core include iron core body and clamp the component of iron core body.Iron core body is formed by stacked before and after lamination, intermediate portion
Divide for suit coil, the part is also referred to as iron core column.Its top and bottom is 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, while making as mounting framework
With.The magnetic conductor of iron core is the magnetic circuit of transformator, and it switchs to magnetic energy the electric energy of primary circuit, and is changed into by the magnetic energy of oneself
The electric energy of secondary circuit, is the medium of energy conversion.Therefore, iron core is significant for transformator.
The manufacture process of transformator generally require an iron core body carry out closed assembly, mounting coil in iron core column and use
Clamping device is clamped fixation to iron core body.If iron core body effectively can not be clamped, lamination will be in alternation magnetic
Under field action, it is magnetostriction that minor variations occur, so as to produce noise.If coil is directly assembled loosely with iron core body
Gu, then noise can be increased.Further, since upper yoke is deposited in above iron core column, stacking it is highly wayward, cause thus to produce
The stress of raw lamination is wayward.
Existing iron core body typically has two kinds of structures.The first, as shown in figure 1,10 structure of iron core body is positioned at upper
The E shape iron core blocks 11 of lower section are to inserting structure.As structure problem, this structure are often insecure with the assembling of coil, cause to become
When depressor works, coil is loose, produces noise.Second, as shown in Fig. 2 iron core body 10 includes the upper ferrum for 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
12 length it is identical and parallel to upper yoke block 12 below, iron core column block 13 is vertically connected on upper yoke block 12 and lower yoke block 14
Between.This structure the disadvantage is that, upper yoke block 12 is deposited in 13 pieces of tops of iron core column, stacking it is highly wayward, lead
Cause the stress of resulting lamination wayward, be also easy to produce noise.
Generally speaking, in prior art, transformator there are problems that many.During transformer manufacturing, due to the knot of iron core body
Structure problem, iron core body effectively can not be clamped, insecure with the assembling of coil.Transformator easily produces noise.In addition, by
There are substantial amounts of leftover pieces when the size and shape problem of iron core block, the material for making iron core block, these corners greatly increase
The manufacturing cost of iron core.
