Abstract
A self-adhesive two composite wires, two wires are disposed in parallel along the cross direction of coils, two wires are disposed in parallel and superposition along the cross direction, the superposition surfaces of two wires are conglutinated into one via the double-sided insulating tape, and the outer parts of two wires are wrapped into one via the insulating paper. The utility model solves the technical problems of weak anti-short ability in the background technology as well as high production cost. Under the conditions of retaining the original characteristics of the wire, a plurality of wires are conglutinated into one, eliminating the paper wrap turn insulation of single wire, improving the filling coefficient of coils and iron window and space utilization ratio of transformer with simple structure, convenient process, reliable product performance, as well as wide scope of application.
Description
Technical field
The utility model relates to a kind of lead of oil immersed power transformer coil, is particularly useful for the lead of EHV transformer, commutator transformer coil.
Background technology
Transformer coil not only will satisfy the requirement of electrical strength, also requires to have enough mechanical strengths, especially anti-short circuit capability.At present, homemade transformer mainly adopts the high mechanical properties lead to improve the transformer anti-short circuit capability.Concrete measure is as follows:
The first increases the yield strength of strip conductor, to improve the transformer anti-short circuit capability.The yield strength of lead increases, and huge short-circuit impact electric current not only makes winding wire be subjected to very big electric power, and coil temperature is sharply raise, and at high temperature, the mechanical strength of winding wire can descend rapidly.
It two is to adopt self-adhering transposed conductor.This lead needs special equipment, technological equipment and detecting instrument when coil is worked out, cost is higher, and because welding is complicated, restricted application.
Summary of the invention
The purpose of this utility model is to provide a kind of self-adhesion two compound wires, and it has solved the technical problem that anti-short circuit capability is weak in the background technology, cost of manufacture is high.
Technical solution of the present utility model is:
A kind of self-adhesion two compound wires, comprise two leads 2,4, its special character is: described two leads 2,4 along the width of cloth to setting arranged side by side, superimposed, the superposed surfaces of described two leads 2,4 is bonded as one by double-sided insulation adhesive tape 3, and the outside of described two leads 2,4 is wrapped by insulating paper 1 to be one.
The dual-side of above-mentioned double-sided insulation adhesive tape 3 constitutes the anti-creep electric insulation along 5 along stretching in outside two leads, 2,4 superposed surfaces respectively.
Above-mentioned double-sided insulation adhesive tape 3 is good with the double-sided insulation adhesive tape that adopts band adhesion layer glued membrane.
Above-mentioned two leads 2,4 all can adopt naked strip conductor.
The utlity model has following advantage:
1. the double-sided insulation adhesive tape of band adhesion layer glued membrane is bonded as one two leads, and under the situation that does not change the lead primary characteristic, the coil overall mechanical strength improves, and the whole anti-short circuit capability of coil strengthens.
2. saved the paper bag turn insulation of solid conductor, improved the activity coefficient of coil and barred window, improved the space availability ratio of transformer, made the high reduction of window unshakable in one's determination, the transformer cost reduces.
3. the reliability of wire insulation can be guaranteed in two anti-creep electric insulation edges that bonding lead both sides are provided with, and strengthens the anti-short circuit capability of lead.
4. simple in structure, technology is easy, and the scope of application is wide.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
Drawing reference numeral explanation: 1-insulating paper, 2-lead, 3-double-sided insulation adhesive tape, 4-lead, 5-anti-creep electric insulation edge.
Embodiment
Referring to Fig. 1, direction shown in the arrow B be coil axes to.Two leads 2,4 of the present utility model can be along the coil width of cloth to being set up in parallel, two leads 2,4 along the width of cloth to setting arranged side by side, superimposed, the superposed surfaces of two leads 2,4 is bonded as one by double-sided insulation adhesive tape 3, the outside of two leads 2,4 is wrapped by insulating paper 1 be one, the formation compound wire.The dual-side of double-sided insulation adhesive tape 3 constitutes the anti-creep electric insulation along 5 along stretching in outside the superposed surfaces of two leads 2,4 respectively.Double-sided insulation adhesive tape 3 is good with the double-sided insulation adhesive tape that adopts band adhesion layer glued membrane.Two leads 2,4 are good to adopt naked strip conductor, as: naked flat type copper wire etc.
