Abstract

The utility model relates to a paper-insulated copper-silver alloy single-sided self-adhered enameled combined lead, which has excellent electrical property, mechanical property, adhesive property andsmall overall dimension, and comprises a plurality of single wires and the outsides of the single wires are lapped with an insulated paper; and the single wires comprise copper-silver alloy conductors and insulated layers are coated outside the copper-silver alloy conductors. The paper-insulated copper-silver alloy single-sided self-adhered enameled combined lead is characterized in that the insulated layer is polyvinyl acetal paint and self-adhered paint is coated on a contact surface of adjacent two single wires.

Description

A kind of paper-insulated copper silver alloy single side self-stuck enameled wire assembled conducting wire

(1) technical field

The utility model relates to enamel-cover composite conductor field, is specially a kind of paper-insulated copper silver alloy single side self-stuck enameled wire assembled conducting wire.

(2) background technology

Paper insulation Kufil composite conductor in the past, see accompanying drawing 1, it is by several Kufil single line outsourcing insulating paper 1 wrapped forming, wherein the metallic conductor 4 of single line is the Kufil conductor, the outside coated insulating paper 1 of Kufil conductor, insulating paper thickness is generally 0.30mm～0.45mm, its shortcoming is can not form between each single line an integral body, and the space that insulating paper occupies is very big, composite conductor in the constant voltage drying, press-fit and be easy in the process phenomenon occur toppling over, had a strong impact on the intensity of coil; In addition, when several Kufil single lines outside uses insulating paper wrapped, see accompanying drawing 3, its outermost layer 6 and innermost layer 7 adopt overlapping wrapped, all the other wrapped forms in 5 employing gaps, intermediate layers, complex structure, and the Transformer Winding space availability ratio is low, and volume of transformer is big.

(3) summary of the invention

At the problems referred to above, the utility model provides a kind of paper-insulated copper silver alloy single side self-stuck enameled wire assembled conducting wire, and it has good electric property, mechanical performance, adhesive property, and overall dimension is little.

Its technical scheme is such: it comprises several single lines, described several single line is outside wrapped by insulating paper, described single line comprises the Kufil conductor, described Kufil conductor external packets is covered with insulating barrier, it is characterized in that: described insulating barrier is an acetal paint, and the contact-making surface of described adjacent two single lines scribbles the self-adhesion lacquer.

It is further characterized in that: described self-adhesion paint film width is 1/3～2/3 of a described Kufil conductor width; Described single line quantity is no less than two; Described several single line exterior insulation paper is wrapped, and the two-layer insulating paper self-locking of its outermost is wrapped, and all the other each layer insulating paper opposite joints are wrapped.

Paper-insulated copper silver alloy single side self-stuck enameled wire assembled conducting wire of the present utility model, it adopts the Kufil conductor, have good electric property and mechanical performance, the outside acetal paint that adopts of single line is as insulating barrier, dwindled overall dimension, can improve the winding space utilance greatly, reduce volume of transformer; Scribble the self-adhesion lacquer between the adjacent single line of its composite conductor, can form an integral body after super-dry, the Short Circuit withstand impact capacity is strong.

(5) embodiment

See Fig. 2, Fig. 4, the utility model comprises several single lines, and several single lines are outside wrapped by insulating paper 1, and wherein single line comprises Kufil conductor 4, and Kufil conductor 4 external packets are covered with insulating barrier 2, and insulating barrier 2 is an acetal paint.The contact-making surface of adjacent two single lines scribbles self-adhesion lacquer 3; It is 1/3～2/3 of Kufil conductor 4 width that self-adhesion coats with lacquer 3 film width; When several single line exterior insulation paper 1 was wrapped, two-layer insulating paper 6 self-lockings of outermost were wrapped, and all the other each layer insulating paper 5 opposite joints are wrapped, adopt this wrapped structure, and its structure is compact more, has improved the Transformer Winding space availability ratio, reduces volume of transformer.

In the utility model paper-insulated copper silver alloy single side self-stuck enameled wire assembled conducting wire, it adopts the Kufil conductor is base material, adopt up-drawing method continuous casting---continuous extruding technology production, improved the plasticity of metal, eliminate casting flaw, crystallization again takes place, change the metal structure structure, the inner crystal grain of refinement, thereby the electric property and the mechanical performance of raising metal; 20 ℃ of resistivity of Kufil conductor≤0.016903～0.017540 Ω mm2/m; Yield strength Rp0.2 〉=300N/mm2, and do not have significant change 80 ℃～150 ℃ long-play yield strengths; That the recrystallization temperature of Kufil conductor and hot mastication temperature are wanted is high 80 ℃～and about 100 ℃, and have favorable conductive heat conduction, and can improve the radiating effect of coil, reach the purpose that improves the coil working temperature; The single line insulating barrier adopts the acetal paint film to substitute insulating paper, and coats 1/3～2/3 epoxy self-bonding paint between adjacent single line, and the single line size reduces 0.25mm, and forms an integral body after advancing super-dry between the composite conductor single line, improves the Short Circuit withstand impact capacity; Little and the basically identical of its overall dimension, the transformer coil of use the utility model product coiling, coil dimension reduces 50mm～250mm, effectively raises the winding space utilance, has reduced volume of transformer; Adapt to the transformer of temperature rise with the coil of the utility model production, allow transformer 80 ℃～150 ℃ long-time overload operations of high temperature, high temperature long-time running mechanical performance does not descend.
