Abstract
The invention discloses a novel transformer. The novel transformer comprises a magnetic core, winding shafts, primary windings, secondary windings and insulation elements, wherein the magnetic core is provided with at least one magnetic core arm, the winding shafts sleeve the magnetic core arm, the primary windings and the secondary windings are respectively wound around the winding shafts and arranged along the axial directions of the winding shafts at intervals, an insulation gap is formed between adjacent primary winding and the secondary winding, at least two insulation gaps are formed among the plurality of primary windings and the plurality of secondary windings, and the insulation elements are arranged on the winding shafts and in the insulation gaps. The transformer disclosed by the invention has the advantages of high cooling efficiency, high space utilization ratio and high cost performance, the material usage is reduced, and the overall size of the transformer is reduced.
Description
Technical field
The present invention relates to a kind of novel transformer, belong to transformer technology field.
Background technology
In prior art, the elementary coiling group of transformer, the coaxial level of secondary rolling thread group are configured in the both sides of an insulator closely, and elementary coiling group is close with secondary rolling thread group level to be configured in the same arm of magnetic core, all coiling is not had above connecting portion between another arm of magnetic core and two-arm, only play the effect of required magnetic loop when forming transformer work, the space availability ratio of magnetic core is low.And elementary coiling group and secondary rolling thread group only have a side to be coaxial configuration close to each other respectively, for realizing the good coupling between elementary coiling group and secondary rolling thread group, need the radial number of turn of elementary coiling group to increase, and the axial number of turn reduce.Namely the radial windings number of plies of whole elementary coiling group formation is many, axial winding length is short, similarly, the radial number of turn of secondary rolling thread group is needed to increase, and the axial number of turn reduces, the radial windings number of plies making whole secondary rolling thread group be formed thus is many, and axial winding length is short, easily causes transformer to dispel the heat bad problem; And identical winding turns needs the wire rod of more multiplex amount, material cost increases.In addition, the radial number of plies of elementary coiling group and secondary rolling thread group increases, and can increase the overall dimensions of transformer.Therefore, the structure of transformer haves much room for improvement.
Summary of the invention
For above-mentioned deficiency, the invention provides a kind of novel transformer, have that volume is little, coupling good and the feature that thermal diffusivity is good.
The present invention adopts technical scheme as follows:
A kind of novel transformer, comprises magnetic core, roll, elementary coiling group, secondary rolling thread group and insulating part; Described magnetic core has at least one magnetic core arm; Described roll is set on described magnetic core arm; Described elementary coiling group and secondary rolling thread group respectively winding on described roll and along the axially spaced layout of described roll, form clearance for insulation between adjacent described elementary coiling group and secondary rolling thread group, between multiple described elementary coiling group and secondary rolling thread group, form at least two described clearance for insulations; Described insulating part to be located on described roll and to be positioned at described clearance for insulation.
Further, described magnetic core is U-shaped or I shape.
Further, described insulating part and described roll are integrally formed.
Compared with prior art, beneficial effect of the present invention is: transformer radiating efficiency of the present invention is high, saves material usage, and reduces the overall dimensions of transformer, and space availability ratio is high, and cost performance is high.
Accompanying drawing explanation
Figure 1 shows that structural representation of the present invention.
Embodiment
Embodiment:
Refer to shown in Fig. 1, a kind of novel transformer, comprise magnetic core 1, roll 2, elementary coiling group 3, secondary rolling thread group 4 and insulating part 5; Described magnetic core 1 has two magnetic core arms 11; Described roll 2 is set on described magnetic core arm 11; Described elementary coiling group 3 and secondary rolling thread group 4 respectively winding on described roll 2 and along the axially spaced layout of described roll 2, form clearance for insulation between adjacent described elementary coiling group 3 and secondary rolling thread group 4, between multiple described elementary coiling group 3 and secondary rolling thread group 4, form at least two described clearance for insulations; Described insulating part 5 to be located on described roll 2 and to be positioned at described clearance for insulation.
Further, described magnetic core 1 is U-shaped.
Further, described insulating part 5 is integrally formed with described roll 2.
Transformer radiating efficiency of the present invention is high, saves material usage, and reduces the overall dimensions of transformer, and space availability ratio is high, and cost performance is high.
The above is only the preferred embodiment of the present invention; it should be pointed out that for those skilled in the art, under the premise without departing from the principles of the invention; can also make some improvements and modifications, these improvements and modifications also should be considered as protection scope of the present invention.
