Abstract
The invention discloses a transformer core, which comprises at least two superposed core units, wherein single core unit is formed by superposing a plurality of silicon steel sheets which are similar in shape and unequal in size; the upper end surface and the lower end surface of the single core unit are in an oblong hole form; and two adjacent core units form an arc-shaped cooling channel at the connected part. The core is designed into an oblong section, so that the material amount of the silicon steel sheets is reduced and the production cost is reduced on the basis of ensuring the effective section of the core. The silicon steel sheets in the core are superposed, so that a stepped circular arc beneficial to air motion is formed; heat in the core can be effectively emitted; the temperature of the transformer is lowered; and the service lifetime is prolonged.
Description
Technical field
The present invention relates to transformer technology field, particularly a kind of transformer core.
Background technology
The iron core of tradition oil-filled transformer is circular configuration with winding.The weight of iron core and the iron yoke centre-to-centre spacing of iron core have very big relation, and iron yoke centre-to-centre spacing is more big, and the weight of iron core is more big, and loss is also more big.And iron core cost is shared that proportion is higher in whole transformator cost, so, while not affecting iron core performance, in order to reduce the volume of transformator, reduce the consumption of stalloy, it is generally adopted long circle-shaped iron core structure, as shown in Figure 1.But this long circle-shaped iron core structure is relatively big due to folded thickness, thickness direction heat radiation is relatively slow, causes transformer temperature higher, decreases transformer life.
Summary of the invention
The technical problem to be solved in the present invention is for above-mentioned the deficiencies in the prior art, and provides a kind of transformer core that can reduce iron core material amount, good heat dissipation effect.
For solving above-mentioned technical problem, the technical solution used in the present invention is:
A kind of transformer core, including the iron core unit that at least two superposition is arranged, the stalloy superposition that single iron core unit is similar by several shapes, differ in size is formed, the upper and lower end face of single iron core unit is all in oval hole shape, and adjacent two iron core unit form arc-shaped heat dissipation channel in junction.
The iron core of long round section, is guaranteeing on the basis of effective cross-section of iron core, it is possible to reduce iron core use material amount.
Preferably, described single stalloy is " day " font.
Preferably, it is provided with airway support bar between adjacent two iron core unit.The air channel that axially arranged gas channel supporting bar is formed, adds the arc-shaped heat dissipation channel that iron core unit is formed in junction, it is possible to increase effective area of dissipation of iron core, strengthens radiating effect.
Further, described airway support bar is metal fin, it is preferred to copper material, heat-conducting effect is better.
After the present invention adopts said structure, have the following technical effect that
Core design is long round section by the present invention, is guaranteeing that, on the basis of effective cross-section of iron core, what decrease stalloy uses material amount, has saved production cost.The stalloy stacking of core interior is arranged, and forms the ladder circular arc being beneficial to air flowing, and can effectively leave internal heat unshakable in one's determination, reduces transformer temperature, increases service life.

Detailed description of the invention
For making the purpose of the present invention and technical scheme clearly, below in conjunction with the embodiment of the present invention, technical scheme is clearly and completely described.Obviously, described embodiment is a part of embodiment of the present invention, rather than whole embodiments.Based on described embodiments of the invention, the every other embodiment that those of ordinary skill in the art obtain under the premise without creative work, broadly fall into the scope of protection of the invention.
The present invention relates to the technical characteristics such as stalloy 1, iron core unit 2, airway support bar 3.
Embodiment 1
As in figure 2 it is shown, single stalloy is in " day " font, naturally it is also possible to for other Common Shape.
As it is shown on figure 3, single iron core unit is similar by several shapes, the stalloy superposition differed in size is formed, the size of each stalloy increases successively, forms the upper and lower end face of iron core unit all in oval hole shape.
If the day font that stalloy is middle opening, then the openings of sizes of each stalloy such as can be at the size, it is also possible to increases successively.
As shown in Figure 4, a kind of transformer core of the present invention, including the iron core unit that at least two superposition is arranged, adjacent two iron core unit form arc-shaped heat dissipation channel in junction.
Embodiment 2
The present embodiment and embodiment 1 are distinctive in that, are provided with airway support bar between adjacent two iron core unit, if single stalloy is in " day " font, then airway support bar shape of putting between adjacent two iron core unit can be as shown in Figure 5.
The above airway support bar is metal fin, it is preferred to copper material, heat-conducting effect is better.
Those skilled in the art of the present technique are appreciated that unless otherwise defined, all terms used herein (include technical term and scientific terminology) and have with the those of ordinary skill in art of the present invention be commonly understood by identical meaning.Should also be understood that in such as general dictionary, those terms of definition should be understood that have the meaning consistent with the meaning in the context of prior art, and unless defined as here, will not explain by idealization or excessively formal implication.
With the above-mentioned desirable embodiment according to the present invention for enlightenment, by above-mentioned description, relevant staff in the scope not necessarily departing from this invention technological thought, can carry out various change and amendment completely.The technical scope of this invention is not limited to the content in description, it is necessary to determine its technical scope according to right.
