Description

Transformer core structure

Technical field

The utility model is related to field transformer technology, refers in particular to a kind of Transformer core structure.

Background technology

Transformer is the device for converting alternating voltage, electric current and impedance.Transformer is by magnetic core, skeleton and coil windings group Into coil windings have two or more windings.Winding is collectively referred to as power transformer body with magnetic core, is to set up magnetic field and biography The circuit part of transmission of electricity energy.Existing magnetic core of transformer is generally circular, causes transformer Ae values small, required number of turns compared with Many, copper cash consumption is big, and copper loss is big, and high cost also results in transformer production efficiency low.Therefore, existing magnetic core of transformer is tackled Structure is improved, to solve the above problems.

Utility model content

In view of this, in view of the existing deficiencies of the prior art, its main purpose is to provide a kind of transformer to the utility model Core structure, it is designed as half track type, increases transformer Ae values by by magnetic core center pillar, so that, needed for reduction transformer Number of turns, reduces copper loss, saves copper cash consumption, effectively increases production efficiency.

To achieve the above object, the utility model is using following technical scheme：

A kind of Transformer core structure, includes base plate, center pillar and side column, and the center pillar is in half track type, and its one is vertical It is arranged on base plate, the side column is integrally vertically installed on base plate around center pillar two side and roof, between center pillar and side column D-shaped space is formed, the D-shaped space lower end has the first magnetic core opening and the second magnetic core opening.

As a kind of preferred scheme：Center pillar lower end both sides have an arc fillet respectively.

As a kind of preferred scheme：The center pillar lower surface is flushed with base plate lower surface.

As a kind of preferred scheme：The core length is 13.1mm, and width is 7.35mm, is highly 9.8mm.

As a kind of preferred scheme：The center pillar and side column are highly 4.7mm.

As a kind of preferred scheme：The center pillar width is 5.6mm.

As a kind of preferred scheme：Distance is 11.1mm between the inwall of the side column both sides.

The utility model has clear advantage and beneficial effect compared with prior art, specifically, by above-mentioned technology Knowable to scheme, magnetic core of transformer is constituted by being combined using base plate, center pillar and side column, and center pillar is designed as half track type, should The center pillar of shape makes the Ae values of transformer more than the Ae values of traditional transformer, it is thus possible to needed for reducing transformer around wire turn Number, reduces transformer copper loss, saves copper cash consumption, and reduces cost effectively increases production efficiency.

More clearly to illustrate architectural feature of the present utility model and effect, come right with specific embodiment below in conjunction with the accompanying drawings It is described in detail.

Specific embodiment

As shown in Figures 1 to 4, a kind of Transformer core structure includes base plate 10, center pillar 20 and side column to the utility model 30, wherein：

The center pillar 20 is in half track type, and it is integrally vertically installed on base plate 10, the lower surface of center pillar 20 and the following table of base plate 10 Face flushes, and is respectively provided on two sides with an arc fillet 21 in the lower end of center pillar 20.

The side column 30 is integrally vertically installed on base plate 10 around the two side of center pillar 20 and roof, in center pillar 20 and side column 30 Between form D-shaped space 40, the lower end of D-shaped space 40 has the first magnetic core opening 41 and the second magnetic core opening 42.

Each spot size parameter of the magnetic core is as follows：Entire length A is 13.1mm, and overall width B is 7.35mm, whole height A1 is 9.8mm；Center pillar 20 and the height F of side column 30 are 4.7mm；The width D of center pillar 20 is 5.6mm；The spacing of the both sides inwall of side column 30 It is 11.1mm from E.

Magnetic core model EPD13, compared with traditional EP13, at identical inductance (L), electric current (I) and magnetic field intensity (B) under, the Ae values 33.5mm of EPD-13²The mm of Ae values 19.5 of EP-13², the Ae values of EPD-13 are 1.72 times of EP-13, institute It is the 58% of EP-13 with the number of turn required for him.

Using same line footpath coil windings, if EP-13 is around 10 circles, EPD-13 only around 6 circles, therefore need to use EPD13 coilings, Copper loss is the 60% of EP-13.

Design focal point of the present utility model is to constitute magnetic core of transformer by being combined using base plate, center pillar and side column, and Center pillar is designed as half track type, the center pillar of the shape makes the Ae values of transformer more than the Ae values of traditional transformer, it is thus possible to Number of turns needed for reducing transformer, reduces transformer copper loss, saves copper cash consumption, and reduces cost effectively increases product Production efficiency.

The above, is only preferred embodiment of the present utility model, and not technical scope of the present utility model is made Any limitation, thus it is all according to technical spirit of the present utility model to any trickle amendment made for any of the above embodiments, equivalent variations With modification, still belong in the range of technical solutions of the utility model.
