Embodiment

[0010] A manufacturing method of tin-plated winding wire, the method adopts a Φ3mm copper rod to be thinned to Φ0.20-1.00mm by a wire drawing machine, then anneals and tin-plates to obtain a tin-plated copper conductor, and then passes through a 30-type three-head extruder in sequence Two layers of polyphenylene sulfide insulating layers are extruded on the outside of the tinned copper conductor, and then polyamide resin insulating layers are extruded on the outside of the two layers of polyphenylene sulfide insulating layers.

[0011] The performance of the tinned winding wire obtained by the above method is:

[0012] (1) Production specification range: 0.20~1.00mm;

[0013] (2) Temperature resistance class F (155°C);

[0014] (3) Since the electronic structure of Sn is arranged as (2, 8, 18, 18, 4), there are 4 electrons in the outermost shell, and the electronic structure of Cu is (2, 8, 18, 1), and there is 1 electron in the outermost shell. Therefore, tinned copper cond...

Abstract

The invention relates to a method for manufacturing a tinned winding wire. The method comprises the following steps: firstly, drawing a copper bar with a diameter of 3 millimeters by a drawbench to make a thin copper bar, performing annealing and then tinning the copper bar to obtain a tinned copper conductor; secondly, extruding and cladding two layers of polyphenylene sulfide insulating layers on the outside of the tinned copper conductor in turn by a three-head extruder; and thirdly, extruding and cladding a polyamide resin insulating layer on the outside of the two polyphenylene sulfide insulating layers. Compared with the prior art, the method of the invention is simple, and the heat resistant grade of the product obtained reaches F grade (155 DEG C). Transformers and high-frequency winding coils which adopt the tinned winding wire of the invention are safe, reliable and highly stable; the leakage inductance and the distributed capacitance are obviously reduced; and the high-frequency characteristics and the anti-interference performance of the transformer are obviously improved.

Description

technical field [0001] The invention belongs to the technical field of three-layer insulated winding wires, which are applied to transformers and high-frequency winding coils whose safety standards meet UL1950 and IEC60950, and in particular relate to a manufacturing method of tinned winding wires. Background technique [0002] The three-layer insulated winding wire currently used on transformers is composed of copper conductors, two layers of polyester insulation and outer polyamide insulation. ℃). With the development trend of electronics, telecommunications, and power supply equipment, the temperature resistance grades of Class E (120°C) and Class B (130°C) can no longer meet the requirements of safety, reliability, and stability, and the market urgently needs higher heat resistance grades. Three-layer insulated winding wire. Contents of the invention [0003] The object of the present invention is to provide a manufacturing method of tinned winding wire with higher h...
