Embodiment Construction

[0010] A winding wire manufacturing method, the method uses a Φ3mm copper rod to be thinned to Φ0.10-0.19mm by a wire drawing machine to make a copper conductor, and then annealed and painted to make an enameled wire, and then passed through a 20-type single-screw extruder to Polyester insulating resin is extruded on the outside of the enameled wire to obtain the winding wire.

[0011] The performance that the inventive method obtains for the winding wire of transformer is:

[0012] 1. Production specification range: 0.10~0.19mm;

[0013] 2. Temperature resistance class E (120°C) and B (130°C);

[0014] 3. It has excellent withstand voltage characteristics, the breakdown voltage is greater than 10kV, and has obtained the identification of basic insulation (test voltage 1500Vrms, 1min);

[0015] 4. It can be directly welded without peeling off the outer layer, and the solderability is 420℃≤2S;

[0016] 5. Excellent wear resistance and surface smoothness, static friction coef...

Abstract

The invention relates to a method for manufacturing a winding wire, which comprises the steps of: drawing a copper rod with a diameter of phi 3mm to be between phi 0.10 and phi 0.19mm through a wire drawing machine to obtain a copper conductor; then performing annealing and painting to obtain an enameled wire; and then extruding polyester insulation resin outside the enameled wire through a single-screw extruder to obtain the winding wire. Compared with the prior art, the method is simple; and an obtained winding wire product can replace conventional enameled wires to be applied to transformers and high-frequency winding coils to ensure that the transformers and the high-frequency winding coils have compact structures and reduced cost.

Description

technical field [0001] The invention belongs to the technical field of enameled wires, is applied to transformers and high-frequency winding coils whose safety standards meet UL1950 and IEC60950, and in particular relates to a manufacturing method of winding wires for transformers. Background technique [0002] At present, the enameled wires used in transformers are composed of copper conductors and insulating layers. The voltage of enameled wires is low, and interlayer insulating layers and inner skeleton baffles are required, which makes the transformer very large and cannot meet the miniaturization and high frequency requirements of electronic transformers. Require. Contents of the invention [0003] The purpose of the present invention is to provide a manufacturing method that can replace existing enameled wire products for winding wires of transformers. [0004] The purpose of the present invention can be achieved through the following technical solutions: [0005] ...
