Abstract
The utility model discloses a heavy current high -frequency transformer, the transformer includes primary winding and secondary, secondary encircles on primary winding, secondary's wire winding is the copper foil. Adopt the copper foil to do the winding, can directly assemble, technology easy operation, can not appear with big line footpath the phenomenon that the magnetic core pulled open, the phenomenon of the big out -of -control size of solenoid can not appear yet, moreover, can realize miniaturizing, high -power and heavy current.
Description
Technical field
The utility model relates to field transformer, particularly a kind of big current high frequency transformer.
Background technology
Traditional strong current transformer, when coiling, often adopts thicker wire diameter or stranded wire operation, but large wire diameter is easily pulled open magnetic core, and the large uncontrollable size of line bag.When the number of turn is more, be also unfavorable for heat radiation.
Thus prior art need to improve.
Utility model content
In view of above-mentioned the deficiencies in the prior art part, the purpose of this utility model is to provide a kind of big current high frequency transformer, Copper Foil is adopted to do winding, can direct-assembling, technological operation is simple, there will not be the phenomenon of magnetic core being pulled open by large wire diameter, also there will not be the phenomenon of the large uncontrollable size of line bag.
In order to achieve the above object, the utility model takes following technical scheme:
A kind of big current high frequency transformer, comprise armature winding and secondary winding, described secondary winding is looped around on armature winding, and the coiling of described secondary winding is Copper Foil.
In described big current high frequency transformer, described Copper Foil is exposed outside big current high frequency transformer.
In described big current high frequency transformer, described big current high frequency transformer comprises insulating barrier, and described insulating barrier is arranged between armature winding and secondary winding.
In described big current high frequency transformer, described insulating barrier comprises three-layer insulated wire.
In described big current high frequency transformer, described transformer comprises iron core, and described armature winding is looped around on described iron core.
In described big current high frequency transformer, the number of turn of described armature winding is 17 circles, and the number of turn of described secondary winding is 3 circles.
In described big current high frequency transformer, the long 40mm of described transformer, wide 22.5mm, high 27mm.
Compared to prior art, the big current high frequency transformer that the utility model provides, comprises armature winding and secondary winding, and described secondary winding is looped around on armature winding, and the coiling of described secondary winding is Copper Foil.Copper Foil is adopted to do winding, can direct-assembling, technological operation is simple, there will not be the phenomenon of magnetic core being pulled open by large wire diameter, also there will not be the phenomenon of the large uncontrollable size of line bag, and, miniaturization, high-power and big current can be realized.
Accompanying drawing explanation
The front view of the big current high frequency transformer that Fig. 1 provides for the utility model.
The left view of the big current high frequency transformer that Fig. 2 provides for the utility model.
Embodiment
The utility model provides a kind of big current high frequency transformer, for making the purpose of this utility model, technical scheme and effect clearly, clearly, further describes the utility model referring to the accompanying drawing embodiment that develops simultaneously.Should be appreciated that specific embodiment described herein only in order to explain the utility model, and be not used in restriction the utility model.
Refer to Fig. 1, the big current high frequency transformer that the utility model provides, comprise armature winding and secondary winding 10, described secondary winding 10 is looped around on armature winding, and the coiling of described secondary winding is Copper Foil 110.In other words, described secondary winding 10 is coated on armature winding, and described secondary winding 10 adopts Copper Foil 110 coiling to form.
Copper Foil is adopted to do winding, can direct-assembling, technological operation is simple, there will not be the phenomenon of magnetic core being pulled open by large wire diameter, also there will not be the phenomenon of the large uncontrollable size of line bag, and, miniaturization, high-power and big current can be realized.
Further, described Copper Foil 110 is exposed to be placed on outside transformer body by shaping Copper Foil outside described big current high frequency transformer, is conducive to heat radiation.
Described big current high frequency transformer also comprises insulating barrier 20, and described insulating barrier 20 is arranged between armature winding and secondary winding 10.Armature winding and secondary winding 10 separate by described insulating barrier 20, avoid both to occur short circuit, improve the safety of big current high frequency transformer.Described insulating barrier 20 comprises three-layer insulated wire, adopts three-layer insulated wire to insulate, and improves fail safe.
Described big current high frequency transformer comprises iron core, and described armature winding is looped around on described iron core.
In the present embodiment, the number of turn of described armature winding is 17 circles, and the number of turn of described secondary winding is 3 circles.Therefore the big current high frequency transformer of the present embodiment is step-down transformer, and power is 1220W, the 100A of resistance to electric current.See also Fig. 2, the long a of described big current high frequency transformer is 40mm, and wide b is 22.5mm, and high c is 27mm.It can thus be appreciated that, adopt Copper Foil as secondary winding, when making the miniaturization of big current high frequency transformer, high-power and resistance to big current can also be realized, expanded the operation strategies of big current high frequency transformer.
Be understandable that; for those of ordinary skills; can be equal to according to the technical solution of the utility model and utility model design thereof and replace or change, and all these change or replace the protection range that all should belong to the claim appended by the utility model.
