Abstract
The utility model provides a film sintering line, comprising a conducting wire body, wherein a polyimide layer is coated outside the conducting wire body; as the polyimide layer is coated outside the conducting wire body, the insulating property and safety of a high transposed wire can be improved; moreover, an insulating layer is only coated outside a piece of insulating paper, therefore, the structure is simple and the manufacturing cost is low.
Description
Technical field
The present invention relates to a kind of lead, particularly a kind of transposed conductor.
Background technology
Transposed conductor is a kind of new material of extensive use in the transformer production field in recent years.Along with the increase of transformer capacity, the sectional area of winding conducting wire also will increase by a certain percentage.But, since receive many factors such as electrical loss index, lead manufacturing condition and user's service condition restriction, can not produce the lead of especially big sectional plane.So just produced new winding conducting wire-transposed conductor.
Now the transposed conductor of technology is many single high-quality enameling copper strap wires or flat wire with paper wrapped to be exchanged arrangement position successively replace on the transposed conductor equipment of special use.At last, the outer coated insulation paper of many enamelled wires after transposition.The transformer that adopts transposed conductor is reduced volume significantly, reduces loss, but this structure is because when turning to coil, be through repeatedly bending, therefore, and outer field insulating paper easy abrasion, thus the fail safe of transposed conductor influenced.
The content of invention
To above-mentioned defective, the invention provides that a kind of insulation property are strong, fail safe good, and film sintered line simple in structure, with low cost.
In order to solve the problems of the technologies described above, a kind of film sintered line of the present invention comprises that wire body, wire body coat polyimide layer outward.
Above-mentioned a kind of film sintered line, wherein, said polyimide layer is a polyimide film.
The present invention can realize following beneficial effect:
1, because wire body coats polyimide layer outward, can improve the insulating properties and the fail safe of transposed conductor, and only outside wire body, coat polyimide layer, therefore, simple in structure and cheap for manufacturing cost.
2, because said polyimide layer is a polyimide film, not only guaranteed the insulating properties of lead, and with low cost.
Description of drawings
Fig. 1 is a structural representation of the present invention
Embodiment
Below in conjunction with accompanying drawing the present invention is described further.
As shown in the figure, in order to solve the problems of the technologies described above a kind of film sintered line of the present invention; Comprise wire body 1, the wire body 1 outer polyimide layer 2 that coats; Since the wire body 1 outer polyimide layer 2 that coats, the insulating properties and the fail safe that can improve transposed conductor, and only outside wire body, coat polyimide layer; Therefore, simple in structure and cheap for manufacturing cost.
In order further to improve the insulating properties of film sintered line, said polyimide layer 2 is coated in polyimides outside the wire body 1 for polyimide film adds man-hour, forms a thin layer through oven dry, gets final product.
In sum, the present invention compared with prior art has that insulation property are strong, fail safe good, and advantage simple in structure, with low cost.
Here description of the invention and application is illustrative, is not to want that therefore, the present invention does not receive the restriction of present embodiment with scope restriction of the present invention in the above-described embodiments, and the technical scheme that any employing equivalence replacement obtains is all in the scope of the present invention's protection.
Claims (2)
1. a film sintered line comprises wire body, it is characterized in that, said wire body coats polyimide layer outward.
2. a kind of according to claim 1 film sintered line is characterized in that said polyimide layer is a polyimide film.
