Description
Technical field
The utility model relates to a kind of wire, particularly a kind of film bag wire for the production of dry-type air-core reactor.
Background technology
Dry-type air-core reactor is widely used in each electric power system, to improving the quality of power supply, plays an important role.But when system switching reactor or special reactor (as test reactor) work, reactor will bear frequency, voltage that amplitude is higher, and too high voltage will cause wire to produce corona phenomenon, and make insulation that electrical breakdown occur prematurely.Wire insulation film mainly adopts the organic films such as polyester, polyimides at present, and its corona-resistance property is poor, can not meet the demand of special purpose reactor.
Summary of the invention
For improving the tolerance of winding conducting wire to corona discharge, extend the useful life of reactor, the utility model is for the shortcoming of prior art, a kind of New insulated wire is provided, adopt resistance to dizzy composite membrane winding lead, thereby make this wire can slow down the damage of corona discharge to wire insulation, extend the reactor life-span.
The technical scheme that the utility model institute technical solution problem adopts is: the resistance to dizzy performance of excellence of dipping lacquer and the resistance to dizzy layer of layer is easily soaked in (appending after claim is determined) novel conductive wire utilization, reaches and improves the discharge inception voltage of dry-type air-core reactor and the object of corona tolerance.
The utility model provides a kind of film bag wire for dry-type air-core reactor, described film bag wire comprise wire and on described wire wrapped resistance to dizzy composite membrane, described resistance to dizzy composite membrane by the outermost resistance to dizzy layer that easily soaks layer, mediates be positioned at insulating barrier the most inboard and that contact with described wire and be composited.
At the film bag wire for dry-type air-core reactor as above, preferably: described resistance to dizzy layer is formed by mica paper.
At the film bag wire for dry-type air-core reactor as above, preferably: described resistance to dizzy layer be quantitatively 50～100g/m
2.
At the film bag wire for dry-type air-core reactor as above, preferably: the width of described resistance to dizzy composite membrane is 8～20mm, and thickness is 0.1mm.
At the film bag wire for dry-type air-core reactor as above, preferably: described resistance to dizzy composite membrane by described easily soak layer, described resistance to dizzy layer and described insulating barrier in order adhering and pressing form.
At the film bag wire for dry-type air-core reactor as above, preferably: the packet stack rate of wrapped described resistance to dizzy composite membrane on described wire is 30～40%.
At the film bag wire for dry-type air-core reactor as above, preferably: the described film bag wire impregnated insulating paint to after wrapped described resistance to dizzy composite membrane, makes described film bag wire be solidified into integral body.
The beneficial effects of the utility model are, do not change the production equipment of insulated conductor, air core reactor, only need to adjust production technology, realize the manufacturing of novel conductive wire, air core reactor, arrive the object that extends the reactor life-span.
Accompanying drawing explanation
Fig. 1 is the main structure chart of the utility model film bag wire.
In figure: 1, easily soak layer; 2, resistance to dizzy layer; 3, insulating barrier; 4, wire.
Embodiment
Below in conjunction with drawings and Examples, the utility model is further illustrated.
A kind of new membrane bag wire for dry-type air-core reactor as shown in Figure 1, comprises wire 4 and wrapped resistance to dizzy composite membrane on wire 4.
Described resistance to dizzy composite membrane by the outermost resistance to dizzy layer that easily soaks layer 1, mediates 2 be positioned at insulating barrier 3 the most inboard and that contact with wire 4 and be composited.Wherein insulating barrier 3 mainly plays the effect of insulation, can select polyester or imines film, and thickness is 25～30 μ m preferably; Resistance to dizzy layer 2 optional use have the mica paper of stronger corona tolerance etc., quantitatively at 50～100g/m
2, to reach, slow down the demolition purpose of corona to insulating barrier 3, slow down the galvanic corrosion damage of corona to main insulation; Easily soak layer 1 optional polyester non woven fabric etc., its one side is bonded together with resistance to dizzy layer 2, and another side, as outermost surfaces, can be avoided the damage of mechanism to resistance to dizzy layer 2 in wrapped process.
First the manufacture method of resistance to dizzy composite membrane is illustrated.To easily soak layer 1, resistance to dizzy layer 2, insulating barrier 3 in order superimposion become resistance to dizzy composite membrane.For example can by adhesive will easily soak layer 1, resistance to dizzy layer 2, insulating barrier 3 in order adhering and pressing form resistance to dizzy composite membrane, described resistance to dizzy composite membrane is soft rectangle film, its width is preferably 8～20mm, and thickness is 0.08～0.2mm, is preferably 0.1mm.
Thereafter, after making resistance to dizzy composite membrane, adopt winding machine, wrapped according to the certain packet stack rate ratio of thin-film width (the overlapping width with), wire is wrapped to being wound around covering wire 4 completely, when wrapped, the one side of insulating barrier 3 in resistance to dizzy composite membrane is contacted with wire 4, make easily to soak layer 1 in outermost.Wherein, packet stack rate is crossed the waste that conference causes resistance to dizzy composite membrane, and packet stack rate is too small can affect its insulation effect again, so packet stack rate preference is as 30～40%.
Finally, for through the wrapped resistance to electrical discharge wire forming, when producing dry-type air-core reactor, complete wrapped wire external layer, be stacked package form easily soak a layer impregnated insulating paint, after final solidifying, make wire become integral body, form novel resistance to dizzy insulated conductor, the mechanical strength and the discharge inception voltage that improve winding, its corona tolerance time can increase by 3～5 times.Herein, insulating varnish adopts the commercially available paint vehicle with insulation property.
In sum, by adopting the structure of appending resistance to dizzy layer and easily soaking layer on the basis of main insulating layer, adopt three-layer combined resistance to dizzy composite membrane of the present utility model, only need wrapped rear simple impregnated insulating paint, just can make wire become integral body, can make full use of the resistance to dizzy performance of excellence of resistance to dizzy layer, reach and improve the discharge inception voltage of dry-type air-core reactor and the object of corona tolerance, and, can not change insulated conductor, the production equipment of air core reactor, only need to adjust production technology, realize novel conductive wire, the manufacturing of air core reactor, arrive the object that extends the reactor life-span.
As known by the technical knowledge, the utility model can be realized by other the embodiment that does not depart from its Spirit Essence or essential feature.Therefore, above-mentioned disclosed embodiment, with regard to each side, all just illustrates, and is not only.All changes within the scope of the utility model or within being equal to scope of the present utility model are all included in the utility model.
