Description
Technical field
The utility model relates to a kind of paper-wrapped copper-silver alloy sheet wire, and specifically a kind of novel power transformer winding wire structure belongs to coil windings line technology field.
Background technology
In prior art, the existing power transformer because its special operation condition demand does not change on the material for a long time, uses oxygen-free copper as conductor material, the limit that become such as conduction, heat conduction, intensity on the winding wire material with the winding wire material always.Have more excellent every performance though compare silver metal with copper, as a kind of precious metal, the price factor has restricted its use.
Summary of the invention
The purpose of this utility model is to overcome above-mentioned weak point, thereby provide a kind of paper-wrapped copper-silver alloy sheet wire, it has better conductance and mechanical strength, utilizes the alloy hierarchy can reduce the eddy current of transformer generation in service, and can improve the efficient of transformer.
According to the technical scheme that the utility model provides, paper-wrapped copper-silver alloy sheet wire comprises the Kufil basis material, and feature is: the single-phase melt layer of plated copper silver alloy, fine silver layer, paper bag insulating barrier successively on the Kufil basis material.
Compared with the prior art the utility model has the following advantages:
The utility model has used the lenticular wire structure to increase the copper factor of transformer coiling, the Kufil material has improved the recrystallization temperature and the creep strength of winding wire, make it have better conductance and mechanical strength, through test, conductance can reach 102%IACS, and tensile strength can reach 280Mpa, utilize the alloy hierarchy to reduce the eddy current of transformer generation in service, can improve the efficient of transformer, with the cost ratio that increases, the performance that transformer promotes has more attraction.
Description of drawings
Fig. 1 is the utility model structural representation.
Embodiment
Embodiment during following the utility model is incited somebody to action in conjunction with the accompanying drawings is further described:
As shown in Figure 1, comprise Kufil basis material 1, the single-phase melt layer 2 of Kufil, fine silver layer 3, paper bag insulating barrier 4.
The utility model forms Kufil basis material 1 according to the continuously extruded shaping of the copper silver metal of specification proportioning silver content 0.05%～0.15% mass fraction back, the single-phase melt layer 2 of plated copper silver alloy, fine silver layer 3 successively on Kufil basis material 1, paper bag insulating barrier 4.At first utilize laser silver coating 60S ± 10S, TRANSIENT HIGH TEMPERATURE reaches and makes copper silver produce the single-phase melt layer 2 of congruent melting formation Kufil more than 960 ℃, and guarantee that shortage of heat is to melt whole fine silver layers 3, single-phase melt layer 2 thickness of Kufil keep 0.005 ± 0.001mm, fine silver layer 3 thickness keep 0.005 ± 0.001mm, because of there is fillet R in the lenticular wire structure, even for coating, utilize surplus temperature to cross one shaping mould during coating and guarantee surface quality.By the wrapped paper insulation of wrapped equipment self-locking form paper bag insulating barrier 4 after after the traction compacting rolling paper-wrapped copper-silver alloy sheet wire.
The utility model utilizes laser to plate silver layer according to wire gauge after continuously extruded then, the plating time in the control, make and between silver layer and Kufil basis material, form the single-phase melt layer of copper silver, make whole alloy wire cored structure intensity increase, re-use wrapped equipment core is improved its dielectric strength according to the wrapped mode of self-locking after wrapped.Skin effect is arranged during current delivery, so the electric conductivity of silver layer is not fully exerted, because paper-wrapped copper-silver alloy sheet wire has been taked hierarchy, the material behavior property of there are differences between each layer is so can reduce the generation of vortex phenomenon when in use.
