Abstract
The utility model discloses a coil winding structure of a high power push-pull transformer used in a low voltage high current push-pull circuit. The structure comprises a framework and a magnetic core body mounted on the framework. Two primary windings and two secondary windings are wound on the framework. The two primary windings are formed by parallelly winding two copper belts which have a same length and are separated with a safe insulation distance on the framework, and an insulation layer is arranged between adjacent copper belt layers. The two secondary windings are also formed by parallelly winding two copper belts which have a same length and are separated with a safe insulation distance on the framework, and an insulation layer is also arranged between adjacent copper belt layers. Since the primary windings and the secondary windings are respectively formed by parallelly winding a pair of copper belts with the same length, characteristics of an inductance value and the like of the two primary windings are consistent, characteristics of an inductance value and the like of the two secondary windings are also consistent, thus consistency of working conditions and working reliability of the power tubes in the push-pull circuit can be ensured.
Description
Technical field
The utility model relates to the high-power push-pull transformer that uses in the low-voltage and high-current push-pull circuit, refers more particularly to the coil winding structure in this kind transformer.
Background technology
The high-power push-pull transformer that is used for the low-voltage and high-current push-pull circuit; It is primary and secondary respectively to have two coil windings; Because push-pull circuit working particularity; Require the property retentions such as inductance of two elementary windings and two secondary winding in this kind transformer highly consistent, could guarantee the consistency and the reliability of the condition of work of two opposed polarity power tubes in the push-pull circuit like this.But; Two elementary windings in the present high-power push-pull transformer and two secondary winding all adopt the version of copper strips lap wound; The distinct disadvantage of its existence is: in two elementary windings or two secondary winding; The copper strips length overall of nexine winding can be shorter than the copper strips of outer winding; The gap such along with the increase of wire circle can be more obvious, can cause the characteristics such as inductance value of two elementary windings and two secondary winding inconsistent like this, thereby can't guarantee the consistency of two power tube operating states in the push-pull circuit.
The utility model content
The utility model technical issues that need to address are: will provide a kind of characteristic of two elementary windings basic identical, the also coil winding structure of essentially identical high-power push-pull transformer of the characteristic of two secondary winding.
For addressing the above problem, the utility model has adopted following technical scheme.
The coil winding structure of high-power push-pull transformer; Comprise: skeleton; Be installed in the magnetic core array on the skeleton; On skeleton, be wound with two elementary windings and two secondary winding, two elementary windings are wound on the skeleton side by side by the isometric copper strips that is separated with the safe insulation distance between two respectively and constitute, and are provided with insulating barrier between the adjacent copper strips layer; Two secondary winding also are wound on the skeleton side by side by the isometric copper strips that is separated with the safe insulation distance between two respectively and constitute, and also are provided with insulating barrier between the adjacent copper strips layer.
Further, the coil winding structure of aforesaid high-power push-pull transformer, wherein: the length of insulating barrier is greater than the length of copper strips, and the Partial Inverse that insulating barrier grows copper strips is to the outside that covers the copper strips end.
The beneficial effect of the utility model is: since primary and secondary winding respectively by a pair of isometric copper strips side by side coiling constitute; Therefore the characteristics such as inductance value of two elementary windings are consistent; The characteristics such as inductance value of two secondary winding are also consistent, thereby can guarantee the consistency of the condition of work of two power tubes in the push-pull circuit and the reliability of work.
Description of drawings
Fig. 1 is the sketch map of the winding process of elementary winding in the coil winding structure of the described high-power push-pull transformer of the utility model.
Fig. 2 is the structural representation after elementary winding technique is accomplished in the coil winding structure of the described high-power push-pull transformer of the utility model.
Embodiment
Below in conjunction with accompanying drawing the coil winding structure of the described high-power push-pull transformer of the utility model is done further detailed explanation.
As shown in Figure 1, be the winding process sketch map of elementary winding in the coil winding structure of the described high-power push-pull transformer of the utility model; As shown in Figure 2, be the structural representation after elementary winding technique is accomplished in the coil winding structure of the described high-power push-pull transformer of the utility model.Because the winding process and the winding structure of secondary winding are identical with elementary winding, so be that example is explained with elementary winding only in the present embodiment.
Referring to Fig. 1, shown in Figure 2; In the present embodiment; Magnetic core array 2 is installed on skeleton 1, on skeleton 1, is wound with two elementary windings, its winding process and winding structure are: two isometric copper strips 51 and 52 are pasted on the insulating barrier polyimide adhesive tape 3; Leave enough secured electrical distances between two copper strips 51 and 52, then copper strips and insulating barrier polyimide adhesive tape 3 are wrapped on the skeleton 1 from level to level.In the present embodiment; The length of insulating barrier polyimide adhesive tape 3 is greater than the length of copper strips 51 and 52; Like this, after the copper strips coiling was accomplished, the polyimide adhesive tape 3 that grows can reversely cover the end of copper strips 51 and 52; Form overhang insulation cover layer 31, with the pad of protection copper strips and its lead-out wire.In actual fabrication, on the lead end that copper strips 51 and 52 lead-out wire 41 and 42 can cause on the skeleton 1.The winding method of secondary winding is identical with elementary winding with winding structure, repeats no more.
The coil winding structure of above-mentioned high-power push-pull transformer; Since primary and secondary winding respectively by a pair of isometric copper strips side by side coiling constitute; Therefore the characteristics such as inductance value of two elementary windings are consistent; The characteristics such as inductance value of two secondary winding are also consistent, thereby can guarantee the consistency of the condition of work of two power tubes in the push-pull circuit and the reliability of work.
