Abstract

The utility model discloses a rectangular transposition aluminum core wire for an ultra-high-voltage hollow smoothing reactor and relates to the technical field of production of the rectangular transposition aluminum core wires for the ultra-high-voltage hollow smoothing reactor in the transformer industry. The rectangular transposition aluminum core wire for the ultra-high-voltage hollow smoothing reactor comprises a wire core with a rectangular section and consisting of a plurality of conductors, each conductor comprises an aluminum line and at least one layer of polyimide film externally wound around the aluminum line, and the polyimide film and polyester composite non-woven fabric are sequentially wound around outside the wire core. In the rectangular transposition aluminum core wire disclosed by the utility model, the round aluminum line is taken as a conductor, and two layers of polyimide films are additionally arranged outside the round aluminum line, therefore, the withstand voltage among wires can be up to over 10,000V; in addition, corona-resisting and frequency-conversion materials are additionally arranged outside the final products, so that the products finally self resist ultra-high voltage, has no influence on outside and also cannot be influenced by outside.

Description

The hollow smoothing reactor of superhigh pressure is with rectangle transposition aluminium core lead

Technical field

The utility model relate to a kind of transformer industry with the hollow smoothing reactor of superhigh pressure with rectangle transposition aluminium core lead production technical field.

Background technology

The transformer industry development of nearly 2 years China is rapid, and the reactor cause has also obtained bigger development simultaneously, and the instructions for use of reactor also is increasingly high, but there is following defective in existing lead, and often result of use is not as people's will, and its defective is following:

1, during the single coiling of common aluminum steel, can only bear 10 volts between line below magnitudes of voltage; This product belongs to the combined product of multi cord, and every conductor must bear bigger magnitude of voltage, so necessarily require that insulation layer structure is good between single line.

2, during many coilings of common aluminum steel and since strand between to produce the not isometric resistance that influences between line of coiling uneven, thereby cause that eddy current loss is excessive to be inevitable, so not only cause the waste of the energy, and the transformer hidden danger that the temperature rise of generating heat brings also is fatal.

Summary of the invention

The utility model is to above-mentioned defective, and the hollow smoothing reactor of superhigh pressure that purpose is a kind of long service life to be provided, to keep the superperformance state for a long time is with rectangle transposition aluminium core lead.

The utility model comprises the rectangular core of being made up of many conductors of section, and every conductor comprises aluminum steel and the winding at least one strata imide membrane outside aluminum steel, winding polyimide film and polyester compound nonwoven cloth successively outside said core.

The utility model also can be established polyimides reinforcement mica tape between polyimide film and compound nonwoven cloth.Polyimides reinforcement mica tape is that the mica paper that requires with special type is a base material; With anti-corona and resistant to elevated temperatures adhesive is adhesive; Single face reinforcement mica tape is reinforcement with the polyimide film; Article thickness is even, mica content is high, it not only can increase the resistance to elevated temperatures of product, has also strengthened the corona-resistance property of product.

The utility model has the advantages that:

1, adopts the circle aluminum steel as conductor, add the two layers of polyimide film, can make like this to reach proof voltage between line and reach more than 10000 volts at aluminium round wire.

2, many single lines are replaced (intercept is big as far as possible), increase silastic material during transposition and avoid injuring insulating barrier; Multiple conducting wires after the transposition is pressed square one-tenth two row's multiple row structures, realize isometric transposition fully.

3, outside final products, increase anti-corona and frequency conversion material, when making product finally self bear superhigh pressure, do not have influence to external world, again can be by external interference.

Description of drawings

Fig. 1 is a kind of structural representation of the utility model.

Embodiment

1) adopt solid-state aluminum wire drawing oil to justify line and draw, the speed of drawing is 700～1000m/min, and the wire drawing speed ratio is 1.25;

2) aluminum steel is carried out aerobic annealing in 4 hours under 380 ± 10 ℃ of temperature conditions;

3) outside aluminium round wire, adopt the two layers of polyimide film wrapped, wrappedly put up 33%, two-layer between the slit do not allow overlapping;

4) many single lines are replaced into one core, the pitch of transposition is 22～28mm;

5), form the rectangular matrix structure of two row's multiple row sections to becoming the core pressure side of thigh;

6) Cross section Design according to product makes up transposition pressure side line; Wrapped successively three-layer thin-film is wrapped outside the core of single row or multiple rows combination: the ground floor polyimide film; The second layer is a polyimides reinforcement mica tape; Outermost layer is non-woven fabric compounded polyimide film, forms peripheral protective layer.

7) rolling, product inspection.

8) product structure is as shown in Figure 1, and the rectangular core 1 of section is made up of conductor 2, and every conductor 2 is provided with aluminum steel 2-1 and at least one strata imide membrane 2-2 of winding outside aluminum steel 2-1.

Winding polyimide film 3, polyimides reinforcement mica tape 4 and polyester compound nonwoven cloth 5 successively outside core 1.
