Abstract
The utility model relates to a compound enameled aluminum transposition wire which includes aluminum conductor wire cores, a compound paint insulating layer, lining paper and an insulated coating; the aluminum conductor wire cores coat the compound paint insulating layer and are arranged into two rows in odd number; the lining paper is arranged in the middle of the aluminum conductor wire cores and the compound paint insulating layer; after transposition, the insulated coating is twisted outside the whole transposition wire core; the compound paint insulating layer is a 200-class EIW/PPEAI compound paint insulating layer; and the material of the insulated coating is polyester fibre non-woven fabric. The compound enameled aluminum transposition wire has the characteristic of using aluminum to replace copper, which reduces the cost; when the compound enameled aluminum transposition wire is applied into a coil cast by epoxy resin, the defect of weak mechanical strength thereof is recovered. Secondarily, the 200-class EIW/PPEAI compound paint insulating layer serving as the transposition wire and the insulated coating of single-silk yarns are adopted, thereby effectively improving the service life of the coil under a high temperature environment. The compound enameled aluminum transposition wire has the advantages of simple structure, reasonable design, safe and reliable performance and very obvious application effect.
Description
Technical field
The utility model relates to a kind of electromagnetic wire call wire body, particularly a kind of compound enamel-cover aluminum transposition conductor.
Background technology
Transposed conductor refers to two row that the enamel-cover edge-wind group live width face with certain radical is in contact with one another, on request on two row enameled sheet wires and below do the same transposition that turns to along narrow limit, and outside it, do continuous wrapped winding wire with electrician's insulating paper; Transposed conductor generally uses enameling copper strap wire as its core material, and it has, and thermal diffusivity is strong, and the saving coil twines, and the advantages such as circulation loss of reduction coil are widely used in the winding of the above oil-immersed type transformer of 220kV.
Though the more common winding wire product of transposed conductor has multiple advance, but because its conductor material is that the electrician uses copper, the manufacturing cost height, the difference of existing market copper, aluminium price is about 4 times, serious restriction its scope of application, have only at present in the power transformer of electric pressure more than 220kV just to be used, and be subjected to the restriction of product market price in the more wide medium and small distribution transformer winding field of market scope, can only use winding wire product than low side.
Therefore, providing a kind of simple in structure, reasonable in design, dependable performance, widely used compound enamel-cover aluminum transposition conductor, is one of these those skilled in the art problem that should address.
The utility model content
The purpose of this utility model is to overcome above-mentioned weak point, and a kind of compound enamel-cover aluminum transposition conductor of simple in structure, reasonable in design, dependable performance is provided.
The technical scheme that the utility model adopted is for achieving the above object: a kind of compound enamel-cover aluminum transposition conductor is characterized in that this transposed conductor comprises: aluminium conductor core, compound varnished insulation layer, lining paper and insulating coating; Described aluminium conductor core applies compound varnished insulation layer, becomes two row by the layout of odd number root, and the centre is provided with lining paper, after transposition, at integral body transposition core outside lapped insulation coating layer; Described compound varnished insulation layer is 200 grades of compound varnished insulation layers of polyester-imide/polyamidoimide; Described insulating coating material is a nonwoven polyester fabric.
The beneficial effects of the utility model are: the characteristics of this transposed conductor are to replace copper material with aluminium, have reduced cost, are applied in the coil of epoxy resin casting at it, have remedied the weak defective of its mechanical strength.Next has adopted 200 grades of polyester-imides/polyesteramine imide enamelled wire varnishes as the transposition core, monofilament lines be coated with insulating layer coating, thereby effectively improve the useful life of coil under hot environment.The utility model is simple in structure, and is reasonable in design, and performance is safe and reliable, the effect highly significant.
Description of drawings
Fig. 1 is the utility model structural representation;
Among the figure: 1 aluminium conductor core, 2 compound varnished insulation layers, 3 lining papers, 4 insulating coatings.
Embodiment
Below in conjunction with accompanying drawing and preferred embodiment, details are as follows to embodiment, structure, feature that foundation the utility model provides:
As shown in Figure 1, a kind of compound enamel-cover aluminum transposition conductor (below be of a size of nominal size), comprise: aluminium conductor core 1 is an example with 2.00mm * 5.00mm/15 root, compound varnished insulation layer 2 can adopt commercially available 200 grades of polyester-imides/polyesteramine imide enamelled wire varnishes as the transposition core, monofilament lines be coated with insulating layer coating, can effectively improve like this and use the useful life of coil under hot environment.Be of a size of through the enameled aluminium flat wire core after the japanning: 2.13mm * 5.16mm, become two row with the layout of odd number root enamel insulated aluminium wire core in the production, the centre is provided with the lining paper 3 of 0.13mm * 14mm; Profile after forming through transposition again is 17.04mm * 10.45mm, and after transposition core external spiral coated the thick nonwoven polyester fabric insulating coating 4 of 4 times of 0.05mm, promptly forming overall dimension was the finished product transposed conductor of 17.44mm * 10.85mm.
The utility model is with the core material of enameled aluminium flat wire as transposed conductor, though the mechanical strength of aluminium conductor and conductivity are all a little less than copper, but it is applied in the coil of poured with epoxy resin, be that the low characteristic of mechanical strength is just effectively remedied, simultaneously because the employing enamelled wire is a core, thereby reduced the insulation thickness size, the sectional area of lead can be improved in the space that saves, thereby has remedied the defective of aluminum conductor than the copper poorly conductive.Density owing to aluminium is 30% of copper simultaneously, and coil is insulated by the number of turn (being length), and the aluminum steel length of equal quality is 3 times of copper, thereby has saved a large amount of production costs.
In implementation process and since the mechanical strength of aluminium than copper material a little less than, therefore should note the adjustment of laying tension and transposition head in process of production, laying tension adopts the felt clamping plate of secondary tension force; Can adopt the rotary push and block mode production effect of import transposition head better.
Above-mentionedly with reference to example this compound enamel-cover aluminum transposition conductor being described in detail, is illustrative rather than determinate, therefore in the variation and the modification that do not break away under the utility model general plotting, should belong within the protection range of the present utility model.
