Abstract

The utility model relates to a twelve-strand vertical arrangement and combination wire, which comprises bare copper flat wires, dried wax layers, first insulation paper layers, and a second insulation paper layer. Each bare copper flat wire is wrapped with one dried wax layer outside; the bare copper flat wires wrapped with the dried wax layers are combined from top to bottom through broadsides; combined bare copper flat wire groups are wrapped with the first insulation paper layers for forming a three-combination wire; and four three-combination wires are placed and arranged vertically and are wrapped with the second insulation paper layer on the external surface. With a single conductor possessing no insulating layer, the twelve-strand vertical arrangement and combination wire saves transformer winding space greatly, has an improved duty ratio, and reduces a transformer volume and production cost. Being arranged vertically in the transformer winding, the twelve-strand vertical arrangement and combination wire realizes failing transverse magnetic flux leakage of an iron core in a minimum width direction of the wire and thus reduces magnetic flux leakage loss substantially, thereby being a novel scientific and technological product for energy saving transformers.

Description

12 vertical array composite conductors

Technical field

The utility model belongs to the electric equipment technical field, is specifically related to a kind of 12 vertical array composite conductors.

Background technology

Existing plain edition paper bag composite conductor structure as shown in Figure 1, it is the folded wire harness of making of form that pastes mutually with broadside by 2 to 4 single paper covered wire or enameled sheet wire, with the wrapped winding wire of making of multilayer electrician paper, specialize in big-and-middle-sized transformer and make the coil use again, also can be made into the semihard composite conductor.Composite conductor can improve the activity coefficient of transformer, reduces the volume of transformer, reduces production costs.Single flat wire with paper wrapped national standard size, insulation thickness is generally 0.30～0.60mm; Combination core outsourcing insulation thickness is generally by national standard or according to customer requirement.Specification: with the bare copper flat wire requirement, a limit 0.8-3.5 mm, b limit 4.0-16.0 mm, insulation adopts telephone paper, cable paper, 500kv transformer turn-to-turn insulation paper as insulation.

Transformer Winding is used and is made up the paper bag lead both at home and abroad in the past, and all adopting for sleeping in is 4 to (being wide pastes mutually) arrangement and maximum radical, is arranged in mode as shown in Figure 2, is common many assemble lines arrangement mode.

This kind composite conductor is because radical in parallel is less, and the lead conductive cross-sectional area is limited, and is can electric current transmitted limited, can not be suitable for high-power transformer, big electric current needs.

Summary of the invention

The purpose of this utility model is to provide a kind of 12 vertical array composite conductors.

12 vertical array composite conductors that the utility model proposes, form by bare copper flat wire 1, dried cured layer 2, first insulating paper layer 3 and second insulating paper layer 4, every bare copper flat wire 1 outer all being coated with is done cured layer 2, per 3 bare copper flat wires 1 that are coated with dried cured layer are superimposed from top to bottom along wide face, outer first insulating paper layer 3 that coats of bare copper flat wire group after superimposed obtains 3 assemble lines; The 43 vertical dischargings of assemble line vertically come into line, and the outer surface of 4 group of 3 assemble line coats second insulating paper layer 4.

In the utility model, doing cured layer thickness is 0.01-0.02mm.

Manufacture method of the present utility model is as follows:

Be 3.15mm by 3 thickness earlier, width is the bare copper flat wire of 8.0mm, once wrapped first insulating paper layer after making up by Fig. 1 arrangement mode, carry out 90 degree upsets again, carry out 43 assemble lines such as the vertical discharging of Fig. 2 at last, vertically come into line, compress the back public insulation in wrapped outside.Be combined into diagram 2 special wire gauges.The application principle of this wire gauge be lead in winding, by laterally leakage field unshakable in one's determination, can reduce winding loss with the minimum widith direction significantly, be the representative lead of energy-conserving product, belong to domestic initiation.

The technological difficulties of this lead are:

1, must avoid during the naked combination of three of solid wires between the naked contact-making surface of each line when take-up, when lead became circular arc by straight line, friction formed the conductive surface Friction mark between the line that causes because of the girth difference, influences electric property.When being the bare wire combination, this solution adds clean dried wax while making up, the strict control of dosage, and cured layer is between 0.01～0.02mm.

2, must carry out 90 degree upsets to the lead that is horizontal combination that once combines handles.Must keep non-displacement between each single line, no perk, indifference ginseng uneven in this process, need correct, leveling, but the ability take-up becomes 4 multiple dish.

3, to twice combination of four assemble lines

Maximum difficulty is to become circular arcs by three straight lines between each line at this moment, emits the change straight line from the circle drum again, because of between each lead of girth difference not being unified unanimity.How to guarantee that the four three vertical leads of combination indifference ginseng behind twice concordant unanimity when wrapped, bag paper is uneven, radian unanimity after the last take-up, difficulty is bigger.And the product line width reaches 45mm, has surpassed all and has held production equipment turnover caliber size.

The beneficial effects of the utility model are:

The utility model can be saved the Transformer Winding space greatly because its single conductor has been cancelled insulating barrier, improves the lead duty ratio, reduces volume of transformer, reduces production costs.

Simultaneously, this lead makes the minimum widith direction of lead obstructed by the horizontal leakage of iron core because of be vertical array (conventional in the past line in contrast) in Transformer Winding, can significantly reduce dispersion loss, is the science and technology research and development new product of energy-economic transformer.In this sciemtifec and technical sphere test of many times, and succeed.

The successful exploitation of this product, energy-saving and cost-reducing for responding country, for industry is promoted energy saving transformer, in power supply, power transmission and transformation device, use and can reduce a large amount of losses, created good social benefit and economic benefit.
