Abstract
The utility model discloses a kind of magnetic core of transformer, including air gap magnetic core and planar magnetic core, described air gap magnetic core and planar magnetic core are disposed as " mountain " font, the center pillar height of air gap magnetic core is less than the inclined post height of center pillar both sides, the center pillar height of planar magnetic core, equal to the inclined post height of center pillar both sides, is filled with epoxide-resin glue between center pillar and the center pillar of planar magnetic core of air gap magnetic core.Air gap magnetic core is connected by epoxide-resin glue with planar magnetic core, epoxide-resin glue has fast and easy and connects air gap magnetic core and the effect of planar magnetic core, additionally, epoxide-resin glue is the most soft, has elasticity, can play the effect of buffering noise reduction, therefore, the noise produced when this utility model can make transformator work is greatly lowered, and meanwhile, promotes the noise specification of the machine product of transformator more to optimize.
Description
Technical field
This utility model relates to a kind of electric elements, more specifically, it relates to a kind of transformator
Magnetic core.
Background technology
When current technology technique is magnetic core of transformer assembling, air gap magnetic core and planar magnetic core it
Between be that directly contact is latter linked, the shortcoming brought is that transformator operationally noise ratio is bigger.
Utility model content
The deficiency existed for prior art, the purpose of this utility model is to provide a kind of transformation
Device magnetic core, solves the problem that transformator operationally noise is big.
For achieving the above object, this utility model provides following technical scheme:
A kind of magnetic core of transformer, including air gap magnetic core and planar magnetic core, described air gap magnetic core is with flat
Face magnetic core is disposed as " mountain " font, and the center pillar height of air gap magnetic core is inclined less than center pillar both sides
Post height, the center pillar height of planar magnetic core is equal to the inclined post height of center pillar both sides, air gap magnetic core
Epoxide-resin glue it is filled with between center pillar and the center pillar of planar magnetic core.
This utility model is further arranged to: the center pillar of described air gap magnetic core with inclined post aspect ratio is
0.6-0.9:1.
This utility model is further arranged to: the center pillar of described air gap magnetic core with inclined post aspect ratio is
0.75:1.
By using technique scheme, air gap magnetic core is with planar magnetic core by epoxide-resin glue even
Connecing, epoxide-resin glue has fast and easy and connects air gap magnetic core and the effect of planar magnetic core, it addition,
Epoxide-resin glue is the most soft, has elasticity, can play buffering noise reduction effect, therefore,
The noise produced when this utility model can make transformator work is greatly lowered, and, promotes meanwhile
The noise specification of the machine product of transformator more optimizes.

Detailed description of the invention
With embodiment, this utility model magnetic core of transformer is described further referring to the drawings.
According to Fig. 1, shown in 2, a kind of magnetic core of transformer, including air gap magnetic core 1 and planar magnetic
Core 2, described air gap magnetic core 1 is disposed as " mountain " font, air gap magnetic core with planar magnetic core 2
Center pillar 11 height of 1 is less than inclined post 12 height of center pillar 11 both sides, in planar magnetic core 2
Post 11 height equal to inclined post 12 height of center pillar 11 both sides, the center pillar 11 of air gap magnetic core 1 with
It is filled with epoxide-resin glue 3 between the center pillar 11 of planar magnetic core 2.
Center pillar 11 and inclined post 12 aspect ratio of air gap magnetic core 1 are 0.6-0.9:1, preferably 0.75:
1。
In conjunction with Fig. 1, shown in 2, air gap magnetic core 1 and planar magnetic core 2 are by epoxide-resin glue 3
Connecting, epoxide-resin glue 3 has fast and easy and connects air gap magnetic core 1 and the work of planar magnetic core 2
With, it addition, epoxide-resin glue 3 is the most soft, there is elasticity, buffering noise reduction can be played
Effect, therefore, the noise produced when this utility model can make transformator work is greatly lowered,
Meanwhile, promote the noise specification of the machine product of transformator more to optimize, be beneficial to it in the field
Popularization.
The method manufacturing above-mentioned magnetic core of transformer, when making production transformator, first by epoxy
Resin glue 3 water is put on the center pillar 11 being coated in air gap magnetic core 1 in magnetic core to be installed in advance, at spot printing
During the amount of glue to guarantee moderate, it is ensured that can be by air gap magnetic core 1 and planar magnetic core 2
Gap between center pillar 11 is completely filled with, then by 2-in-1 to air gap magnetic core 1 and planar magnetic core become
One magnetic core, the magnetic core baking-curing that finally will assemble, thus i.e. can get one and can have
The noise produced when making transformator work of effect can significantly decline, and the complete machine of transformator produces simultaneously
The magnetic core of transformer that the noise specification of product more optimizes.
The application solves the flooding problems of epoxide-resin glue 3 further, in planar magnetic core 2
Overflow launder is offered on post 11, when preventing air gap magnetic core 1 and planar magnetic core 2 from splicing, unnecessary
Epoxide-resin glue 3 wasteway center pillar 11 around groove in.
The above is only preferred implementation of the present utility model, protection model of the present utility model
Enclosing and be not limited merely to above-described embodiment, all technical schemes belonged under this utility model thinking are equal
Belong to protection domain of the present utility model.It should be pointed out that, the ordinary skill for the art
For personnel, without departing from the some improvements and modifications under this utility model principle premise, these
Improvements and modifications also should be regarded as protection domain of the present utility model.
