Abstract

The present invention relates to a winding method for dual continuous type coils wound by using a plurality of parallel conducting wires, which belongs to the technical field of transformer coils. The winding method comprise the steps: firstly, a winding machine is simultaneously wound with a lower cake and an upper cake of an inverse section, wherein the lower cake and the upper cake are provided with lead wires; then, the winding machine is simultaneously wound with a lower cake and an upper cake of a positive section; simultaneously, the winding machine is wound with the temporary section of the upper cake of the inverse section and the temporary section of the lower cake of the inverse section, the temporary section of the upper cake of the inverse section is directly wound outside the upper cake of the positive section, and the temporary section of the lower cake of the inverse section is wound above the upper cake of the positive section; the temporary section of the lower cake of the inverse section is turned and stacked to form the lower cake of the inverse section; the temporary section of the upper cake of the inverse section is turned and stacked to form the upper cake of the inverse section; then the next positive section and inverse section are wound according to the method, and the steps are repeated. The present invention effectively avoid the phenomenon that the conducting wires of two cakes are mutually interfered and kinked when the inverse sections are turned and stacked, and has the advantages of good manufacturability and high work efficiency.

Description

The winding method of the dual continuous type coil of many parallel conducting wire coilings

Technical field

The invention belongs to the Transformer Winding technical field, be specifically related to a kind of winding method of dual continuous type coil of many parallel conducting wire coilings.

Background technology

Some low-voltage coils large-scale, oversize transformer are big owing to capacity at present, voltage is low, extensively adopt the spiral and continuous winding of biserial, but in some extra-high pressure products, be the increase conductor cross-section, reduce radial height, increase axial height and require on local line segment, can regulate the impact characteristics that vertical electric capacity improves whole winding, require to adopt the loop construction pattern of and continuous winding structural advantages spiral in design: co-continuous formula structure in conjunction with biserial.This winding can reduce product cost, but because its upper and lower cake line in the anti-section when anti-section coiling easily produces interferes and kink, makes its rolling technology poor, fails effectively to use in transformer coil.

Summary of the invention

Technical problem to be solved by this invention is the above-mentioned defective at prior art, provide a kind of when coiling the upper and lower cake of anti-section can not produce the winding method of the dual continuous type coil of interference, rolling technology is good, production efficiency is high many parallel conducting wire coilings.

The technical scheme that solution the technology of the present invention problem is adopted is the winding method of the dual continuous type coil of these many parallel conducting wire coilings, and its step is as follows:

1. earlier simultaneously have cake under the first anti-section of lead-out wire and have cake on the first anti-section of lead-out wire in coiling on the coil winding machine;

2. the more positive section of coiling simultaneously cake and positive section go up cake down;

3. the second anti-section of coiling simultaneously goes up interim section of cake and the second anti-section interim section of cake down, and wherein the second anti-section goes up interim section of cake and directly goes up outside the cake around positive section, the second anti-section down interim section of cake around positive section top of going up cake;

4. turn over repeatedly the second anti-section interim section of cake down, it is turned over change into second anti-section cake down;

5. turn over repeatedly the second anti-section and go up interim section of cake, it is turned over change into the second anti-section and go up cake;

Again by next positive section of 2. above-mentioned～5. method coiling and anti-section, so repeatedly.

The present invention dexterously will anti-section in interim section the position change (being about to upper and lower cake in the formal anti-section becomes interim line segment when interim line segment coiling upper and lower cake) of upper and lower cake line, solved the phenomenon that anti-section two cake leads when turning over repeatedly interfere with each other and twist together.

Description of drawings

Below in conjunction with the example accompanying drawing, the present invention is described in further detail.

Fig. 1 is a structural representation of the present invention

Among the figure: the first anti-section that 1-has a lead-out wire down the first anti-section of cake 1 '-have lead-out wire go up cake 2, the positive section of 4-down cake 2 ', 4 '-positive section go up the cake 3-second anti-section down the anti-section of cake 3 '-second go up cake 5-lead-in wire

Embodiment

As shown in Figure 1, present embodiment adopts the coil of two parallel conducting wire coiling co-continuous formulas.Its step is as follows:

1. earlier simultaneously have cake 1 under the first anti-section of lead-out wire and have cake 1 ' on the first anti-section of lead-out wire in coiling on the coil winding machine;

2. the more positive section of coiling simultaneously cake 2 and positive section go up cake 2 ' down;

3. the second anti-section of coiling simultaneously goes up interim section of cake 3 ' and the second anti-section interim section of cake 3 down, wherein the second anti-section goes up interim section of cake 3 ' and directly goes up outside the cake 2 ' around positive section, and the second anti-section interim section of cake 3 down utilizes correcting wedge that paper slip forms around positive section top of going up cake 2 ';

4. turn over repeatedly the second anti-section interim section of cake 3 down, it is turned over change into second anti-section cake 3 down;

5. turn over repeatedly second anti-section interim section of going up cake 3 ', it is turned over change into the second anti-section and go up cake 3 ', carry out the second anti-section go up interim section of cake 3 ' turn over repeatedly the time, the position does not refoot earlier, the direct line of section temporarily turns over repeatedly, then the face position is finished changing, and is past interior that lineation is suitable along the face position, after finding position, position, the end position, the end is finished changing, again the line cake is strained;

Again by next positive section of 2. above-mentioned-5. method coiling and anti-section, so repeatedly.

Since in the vertical coil winding machine, the people that around coil winding machine, can stand, and operator's scope of activities is relatively large, so the coil winding machine among the present invention adopts vertical coil winding machine.

Co-continuous formula structure has adopted 4 and around transposed conductor 1.6 * 5.6/19.55 * 13.62-1.95 * 19 in the present embodiment, and the width of cloth is to (every cake thickness) 120, per coiling on working day 16-20 section (cake).
