Abstract
The utility model relates to a winding structure of a transformer coil, in particular to a winding transposition structure of a high-voltage large-capacity transformer coil winding structure. In the first quarter of the total number of turns, a line 1, a line 2, a line 3 and a line 4 are sequentially arranged from top to bottom; in the second quarter of the total number of turns, the four lines are transposed and then arranged in the following order from top to bottom: the line 2, the line 1, the line 4 and the line 3; in the third quarter of the total number of turns, the four lines are transposed and then arranged in the following order from top to bottom: the line 3, the line 4, the line 1 and the line 2; and in the fourth quarter of the total number of turns, the four lines are transposed and then arranged in the following order from top to bottom: the line 4, the line 3, the line 2 and the line 1. The lines are transposed one by one during transposition to avoid overlapping in the transposition, so the production process is simper, practical and convenient, and the quality of the product is safe and reliable.
Description
Technical field
The utility model relates to the winding structure of transformer coil, specifically relates to the arrangement transposition structure of lead in the high voltage large capcity transformer coil winding.
Background technology
So-called helical winding be exactly each wire turn by many local derviation wire-wound spirality arranged side by side, divide windings such as single-screw, double helix and four spirals.Lead needs transposition, helical winding is the same with solenoid coil all to be to be wound in spirality, not existing together is that the former every circle lead radical arranged side by side is more, and each root lead repeatedly presses, each wire turn do not resemble that solenoid coil abuts one another but in the centre across a space.
Helical winding with continuous winding relatively, the helical winding number of turn is few, the cross section is big, also has bigger support end face, stability is fine when axial short circuit.Therefore, helical winding is applicable to the low-voltage coil of big electric current, perhaps is used for adopting the large-scale power transformer of continuous winding.
At high voltage, in the high-power transformer, much low, middle pressure, sometimes comprise voltage regulation coil, adopt four comparatively thick, hard wire gauges as the transposed conductor, according to traditional in the past interchanging method, make difficulty, even adopt special-purpose transposition instrument, transposition also is difficult for making, and out-of-flatness, easily form the scissors mouth, cause the transformer coil short circuit, influence the safe operation of transformer.
The utility model content
The purpose of the utility model technology is exactly in order to solve the above-mentioned transposition drawback when making, to avoid two traditional structures that stack transposition, a kind of new coiling transposition structure being provided.
A kind of coiling of high voltage large capcity transformer coil transposition structure is positioned at first 1/4th total number of turns, is arranged in order 1. number line, 2. number line, 3. number line and 4. number line from the top down, it is characterized in that:
Be positioned at second 1/4th total number of turns, four lines transposition back top-downs are arranged as: 2. number line, 1. number line, 4. number line and 3. number line;
Be positioned at the 3rd 1/4th totals number of turns, four lines transposition back top-downs are arranged as: 3. number line, 4. number line, 1. number line and 2. number line;
Be positioned at the 4th 1/4th totals number of turns, four lines transposition back top-downs are arranged as: 4. number line, 3. number line, 2. number line and 1. number line.
Further, the sectional area size of described wrap wire height is the 5-25 millimeter, and wide is the 8-20 millimeter.
The utility model has the advantages that, adopt one changes during transposition, avoid two traditional methods that stack transposition, thereby the more simple and practical convenience of manufacture craft, guarantee that product quality is more safe and reliable.

Fig. 2 is the coiling transposition structural representation of this practical high voltage large capcity transformer coil.
Embodiment
Below in conjunction with accompanying drawing, the utility model is described in further detail.
A kind of coiling of high voltage large capcity transformer coil transposition structure comprises being positioned at and twines first 1/4th total number of turns, is arranged in order 1. number line, 2. number line, 3. number line and 4. number line from the top down, it is characterized in that:
Be positioned at second 1/4th total number of turns, four lines transposition back top-downs are arranged as: 2. number line, 1. number line, 4. number line and 3. number line;
Be positioned at the 3rd 1/4th totals number of turns, four lines transposition back top-downs are arranged as: 3. number line, 4. number line, 1. number line and 2. number line;
Be positioned at the 4th 1/4th totals number of turns, four lines transposition back top-downs are arranged as: 4. number line, 3. number line, 2. number line and 1. number line.
Further, the sectional area size of described wrap wire height is the 5-25 millimeter, and wide is the 8-20 millimeter.
A standard transposition is carried out in transposition before improving respectively at 1/4 and 3/4 place of total number of turns, and the transposition after the improvement respectively replaces the top and bottom two lines respectively at 1/4 and 3/4 place, change that two lines stack transposition in traditional interchanging method, between per two, replace respectively and use instead, avoided two lines to stack the curved motionless problem of transposition, particularly transposed conductor and other thick and stiff big wire gauges are made, its benefit is more obvious.And the result of its transposition remains transposition fully, no circulation loss between parallel conducting wire.
