Abstract
The utility model relates to a fundamental insulation winding wire, which comprises a copper conductor, an enameled insulation varnish layer and a polyester insulation resin extruded layer; the enameled insulation varnish layer is arranged outside the copper conductor, the polyester insulation resin extruded layer is arranged outside the enameled insulation varnish layer. Compared with the prior art, the winding wire has the advantages of simple structure and low cost, and can be applied to transformers and high-frequency winding coils instead of the prior enameled cable.
Description
Technical field
The utility model belongs to the enamelled wire technical field, and it is applied to transformer and the high frequency winding coil that safety standard meets UL1950, IEC60950, relates in particular to a kind of basic insulated winding wire that is used for transformer.
Background technology
At present, be used in the enamelled wire on the transformer, be made up of copper conductor and insulating barrier, enamelled wire voltage is low, needs interlayer insulating film and inner frame baffle plate, makes transformer do very greatly, can not satisfy the requirement of electronic transformer miniaturization, high frequency.
The utility model content
The purpose of this utility model is exactly to replace existing enamelled wire product to be used for the basic insulated winding wire of transformer in order to provide a kind of.
The purpose of this utility model can be achieved through the following technical solutions:
The basis insulated winding wire is characterized in that, comprises copper conductor, the enamel insulation enamelled coating, and polyester insulated resin extrudes layer, and described enamel insulation enamelled coating is located at outside the copper conductor, and described polyester insulated resin extrudes layer and is located at outside the enamel insulation enamelled coating.
The specification of described copper conductor is Φ 0.10～0.19mm.
Compared with prior art, the utility model is simple in structure, can save interlayer insulating film and inner frame baffle plate as transformer and high frequency winding coil, make primary and secondary winding close coupling, but transformer reduced volume 1/2 and reduction weight 1/3, can save fee of material and processing charges, and obviously reduce leakage inductance and distributed capacitance, significantly improve the high frequency characteristics of transformer.The utility model can replace existing enamelled wire product to be applied to transformer, can make its structure compact more.
Description of drawings
Fig. 1 is a structural representation of the present utility model;
Fig. 2 is the cross sectional representation of Fig. 1.
Embodiment
The utility model is described in further detail below in conjunction with accompanying drawing.
As shown in Figure 1 and Figure 2, for being used for the basic insulated winding wire structural representation of transformer, the described basic insulated winding wire that is used for transformer extrudes layer 3 by copper conductor 1, enamel insulation enamelled coating 2 and polyester insulated resin and forms.
Use the japanning of after the wire drawing machine drawing-down, annealing of Φ 3mm copper bar, by 20 type list multiple screw extruders polyester insulated resin is extruded in outside the enamelled wire then.
The performance that is used for the basic insulated winding wire of transformer is:
1. production specification scope: 0.10～0.19mm;
2. temperature resistant grade E level (120 ℃) and B level (130 ℃)
3. voltage-resistent characteristic is good, and puncture voltage obtains basis insulation (test voltage 1500Vrms, evaluation 1min) greater than 10kV;
4. need not just can directly weld by peeling outer layer 420 ℃≤2S of solderability;
5. good resistance to wear and surface smoothness, confficient of static friction≤0.133;
6. chemically-resistant solvent and impregnating varnish performance are good.
The GPX-1B basis insulated winding wire and the common UEW Polyurethane enameled wire performance that are used for transformer are more as shown in table 1.
