Abstract
The utility model discloses a film-covered rectangular aluminum stranded conductor used for an extra-high voltage dry-type reactor. The film-covered rectangular aluminum stranded conductor is formed by stranding and interchanging at least four thin-film round aluminum conductors into an upper row and a lower row to form a rectangle and is characterized in that two layers of polyimide films and one layer of polyester non-woven fabric are lapped in half outside the inner layer. The film-covered rectangular aluminum stranded conductor has reasonable structure and skillful concept; the polyester non-woven fabric is lapped outside the semi-finished product of the film-cover round aluminum conductor for fixing impregnating varnish, and then two layers of polyimide films are also lapped, so as to resist the voltage of 6000V and more than 6000V; the polyester non-woven fabric and the impregnating varnish form an insulating layer which has good insulating property and heat-conducting property, thereby greatly improving the electric property and the heat dispersion of the product; in addition, the resin insulating material and the aluminum have the approximate expansion coefficients, thereby reducing the cracking possibility and having high promotional value.
Description
Technical field
The utility model relates to cable equipment technical field, specifically, relates to a kind of reactor with film bag rectangular aluminum twisted wire.
Background technology
In the past, the form of ultra high voltage reactor mostly is oil immersed type greatly, defectives such as inflammable, environmental protection difference are arranged, and adopt the single film aluminum steel that takes all of to twine the reactor coil usually, have again that Internal and external cycle resistance does not wait, eddy current loss is big, twine shortcomings such as trouble and poor stability, has had a strong impact on the function of reactor.It is imperative that dry reactor therefore little, in light weight with volume, environmental protection substitutes the oil immersed type reactor.In order to overcome the defective of oil immersed type reactor, dry reactor is to its main part---and winding wire proposes Internal and external cycle resistance and equates and the requirement of the easy grade of winding.
Summary of the invention
The purpose of this utility model is, provides a kind of and can effectively overcome above-mentioned defective, and the extra-high voltage dry type reactor that Internal and external cycle resistance equates is with film bag rectangular aluminum twisted wire.
For achieving the above object, the utility model adopts following technical scheme:, a kind of extra-high voltage dry type reactor is with film bag rectangular aluminum twisted wire, mainly become rectangle to form, it is characterized in that: double-bag polyimide film and one deck polyester non woven fabric of half-lap successively outside the internal layer by the stranded two rows that replace into of at least four films circle aluminum steel.
Owing to adopt such scheme, be not difficult to draw as drawing a conclusion: the utility model is rational in infrastructure, be skillfully constructed, owing to adopted the technology of stranded transposition, make the take all of equal in length of aluminum steel of each film in this product, thereby guarantee that the take all of resistance of aluminum steel of each root film is equal substantially, for the function that improves the ultra high voltage reactor greatly provides reliable guarantee, after the gluing, each root film takes all of and all is stained with enough 118-1H solvent-free immersion paints between the aluminum steel, thereby driven the air of product inside away, the film outer wrapped polyester non woven fabric of aluminum steel semi-products that takes all of can pin impregnating varnish, wrapped again two layers of polyimide film, ability 6000V and above voltage, the impregnating varnish of outermost layer polyester non woven fabric outer surface and gluing sticks together, after the heat treatment for solidification, impregnating varnish after the curing makes that with take all of aluminum steel and coil turn and circle " pinning " of the film in the coil the take all of stability of aluminum steel stability and coil of film in the coil is better, polyester non woven fabric and impregnating varnish are formed insulating barrier jointly simultaneously, have good insulation performance performance and heat conductivility, the electric property and the heat dispersion of product have been improved greatly, and the coefficient of expansion of resin-insulated material and aluminium is closer to each other, reduce the possibility of cracking, have promotional value.
Description of drawings
Below in conjunction with drawings and Examples the utility model is described in further detail.
Fig. 1 is a structural representation of the present utility model;
Fig. 2 is a local enlarged diagram of the present utility model.
Embodiment
Referring to Fig. 1, Fig. 2, a kind of extra-high voltage dry type reactor is with film bag rectangular aluminum twisted wire, mainly become rectangle to form by at least four film circle aluminum steel 10 stranded two rows that replace into, internal layer outside is double- bag polyimide film 20,30 and one deck polyester non woven fabric 50 of half-lap successively, and polyester non woven fabric outer surface is provided with glue-line 40.
Claims (2)
1. an extra-high voltage dry type reactor is with film bag rectangular aluminum twisted wire, mainly become rectangle to form, it is characterized in that: double-bag polyimide film and one deck polyester non woven fabric of half-lap successively outside the internal layer by the stranded two rows that replace into of at least four films circle aluminum steel.
By the described a kind of extra-high voltage dry type reactor of claim 1 with film bag rectangular aluminum twisted wire, it is characterized in that: polyester non woven fabric outer surface is provided with glue-line.
