Abstract
The invention relates to an energy-saving three-dimensional iron core-coiled transformer which is characterized in that a winding is wound on a core column to form a three-dimensional iron core-coiled transformer, and the cross section of the core column is in an elliptical shape or a long circular shape. The energy-saving three-dimensional iron core-coiled transformer has the advantages that considerable silicon-steel plates and copper wires can be saved, and energy sources are saved.
Description
Technical field
The present invention relates to a kind of transformer, particularly relates to a kind of energy-conservation three-dimensional reel iron core transformer.
Background technology
The iron core of style volume transformer is to adopt the cross section to be circular appendiron core transformer basically at present, and this core section is circular three-dimensional appendiron core transformer, better mechanical property, but bigger waste is arranged on material.
Summary of the invention
Purpose of the present invention just provides a kind of by saving the energy-conservation energy-conservation three-dimensional reel iron core transformer of copper iron realization of transformer.
Solution of the present invention is such: winding is on stem stem, turns to three-dimensional reel iron core transformer, and the cross section of described stem stem is ellipse or Long Circle.
After adopting technique scheme, compare with the traditional round tee section, advantage of the present invention is:
1. the whole height of oval-shaped iron core and width are all little than circular iron core, thereby have reduced iron loss.Be that two kinds of iron core stem stems compare (Fig. 4).(Fig. 5) be long comparison of yoke of two kinds of iron cores.As can be seen from the figure, the iron yoke center of oval-shaped iron core and the distance at post center have all shortened Hc, and the height of whole iron core and width have also reduced Ht, and this has just shortened the loop of magnetic flux.
2. oval or oval iron core is real in circular iron core is divided into two semicircles as (Fig. 6), has increased the rectangle iron core of 2R * δ in the centre.Iron core can be made the sectional area that appropriate adjustment changes iron core with the thickness δ of intermediate rectangular like this, and the girth of winding only has a little increase simultaneously.When guaranteeing that circular cross-section is suitable with long round section, need only δ＞0, just can shorten the length of 2R, just can shorten iron yoke length, thus the save silicon steel disc.
When core section is circle, core section is long-pending will to be increased, peripheral girth must have increment 2 π Δ R, because of circle in the geometric graph of all cylindrical fixed length compositions is maximum area, and have distance between two points the shortest be air line distance, the area that two semicircles are surrounded is a maximum area, and the rectangle part of middle 2RX δ is to the straight length of peripheral circumferential increment Delta 2(R π+δ), and the length of 2R does not increase.
For example: Φ D=210mm, At=325.4cm; Outer circumference L=π 210=659.7mm; Φ D=160mm when adopting oval iron core, rectangle part 2R=160mm, δ=85.4mm; Rectangle part At=188.8cm, total cross section At=325.4cm, peripheral L=160 π+2 δ=673.4mm.
Two kinds of schemes are compared, and the iron core effective cross-section is suitable, and the winding copper consumption is suitable, differs 50mm but iron core Φ D=210mm compares both with Φ D=160mm, and M0 can dwindle 50mm in other words, the corresponding 48kg that reduces of iron core weight.When the identical number of turn of winding, the no-load loss of iron core will reduce so.Promptly under identical no-load loss, the umber of turn of oval iron core just can correspondingly reduce, thereby has saved copper material.
If oval iron core is in application after determining Φ D, needed and the thickness δ of the rectangle part of centre is done suitable adjustment by design, to satisfy the requirement of core section to Electromagnetic Design.When the adjustment of circular iron core, need adjust the size of Φ D, cause the increasing degree of winding copper material to be greater than oval amplitude that increases δ.
In accompanying drawing 7, can see, identical iron yoke length, when core section is circle (as the broken circle in the accompanying drawing 7), central cam diminishes, if make it put down identical radial coil, then need to enlarge central cam, promptly elongate iron yoke length, and oval iron core only need be adjusted the thickness of δ, central cam is enlarged, and iron yoke length need not to extend.
This shows the weight that adopts the Long Circle iron core can save materials such as considerable silicon steel sheet and copper cash.

Embodiment
The present invention includes winding 1, iron yoke 2 and stem stem 3, and winding 1 is on stem stem 3, turns to three-dimensional reel iron core transformer, and the cross section of described stem stem 3 is ellipse or Long Circle.
The transverse of described elliptic stereo volume stem stem with the ratio of minor axis is: major axis: minor axis＞1.
Described cross section is that radius is the circular arc of R and the cross section that the centre is formed by connecting for the rectangle of 2R * δ for the Long Circle stem stem is meant two ends, as shown in Figure 6.
Oval major axis: minor axis=(2R * δ): 2R=1.55～1.65 are o'clock most economical.
