Description

The invention relates to electrical engineering and relates to the technology of manufacturing windings of transformers and reactors.

A known method of manufacturing a continuous winding of an induction device 1 involves winding m parallel wires n coils and making transitions between coils.

The disadvantage of this method is limited technological capabilities. For example, in this way it is impossible to perform a continuous winding with the number of turns in the coil 0.5 or 0.75, that is, with the number of turns less than one

The closest to the claimed method is the method of manufacturing a continuous winding 2, including winding kn with parallel wires and coils, with the number of turns in each coil W A + m / n, where A is a fractional part of

turns, m is the numerator of the fractional part of the fractional number of turns, K is any integer. The method involves dividing wires into two groups, one of which contains km of conductors, where c is the order number of the coil, the first in a pair, the other group contains the remaining conductors, and simultaneous winding of these groups of wires along one coil in two adjacent coils, as well as transitions between coils. However, this method also has limitations, as it is not applicable when A 0 and K 1, i.e. has limitations on the number of turns and coils.

This method does not allow to manufacture a continuous winding with the location of its ends not on one side of the winding, but for example, on opposite sides of it - a winding that is preferable from the point of view of technical and economic indicators

device and simplify its design. So, in the case when the winding is continuous, it is installed on the inner concentrator of the transformer and the ends are located in the channel between the inner and outer concentrations, concentrating the ends on one side of the winding leads to an enlarged channel, increasing the average diameter of the outer end, and consequently, to increased consumption of active transformer materials and its losses.

The aim of the invention is to develop a method of manufacturing continuous-type windings with any number of coils wound with parallel wires, with any identical number of turns in each coil, in which the ends of the windings and transitions would be located on the q sides around the circumference, i.e. development of a continuous winding manufacturing method with wide technological capabilities for induction devices with improved technical and economic indicators.

In order to accomplish this, in the method of manufacturing a continuous winding, in which m parallel wires are divided into two groups, transitions between coils are performed and at the same time two groups of wires W g / nc are wound in two adjacent coils, - parts of the first round of the first

q - 1 - q 1 -3 turn, and in the last part

the last turn of the last coil to wind each part of N 1 / q with wires, the number of which is equal (t - N A, cut off after each part A of the wires.

Starting the winding of the winding by sequential addition of parallel wires from the section to the section of the first turn, provide the location of the ends of the beginning on a specified number of sides.

Further, the process of winding the drying is such that the transitions from the coil to the coil are performed, tdkzhe sequentially shifting them around the circumference of the winding. it

achieved by the fact that as the winding of turns of each group of wires in the previous coil is completed, it proceeds to the next coil and continues

simultaneous winding in two adjacent coils. Thus, the transitions are located on the q sides. .

Similarly, the beginning of the winding is performed with final operations, also ensuring that the ends of the winding are located on a specified number of sides.

The winding performed by the inventive method has a compact construction with a reduced external dimension, which

5 leads to a decrease in the mass and dimensions of the induction device, especially significant when deciding on the internal concentrator. A decrease in the mass and size parameters of the device also makes it possible to reduce the power loss in it. The claimed method is universal, because it does not have. restrictions on the number of turns in kzhushki. nor by the number of coils.

first coil. Thus, the beginning of the winding is made in the vice of the two ends, located on opposite sides of the winding circumference.

 As the wires 1,2 are wrapped around the total number of turns, and the wires 3, 4 are only 0.75 turns, the wires are divided into two groups 5 and b: the first group 5 includes wires 1 2 that start winding the first coil 7, the second group b includes the remaining wires, and group 5 performs the transition 8 from coil 7 to the cat 9.

This group starts winding 1 / q 0.5 turns in coil 9 and at the same time continues to wind 0.5 turns in coil 7 with wires of group 6. After that, the group

wires 6 make the transition 10 from ksushki 7 to coil 9, and, adding them to the group of wires 5, continue to wind all the wires of 0.75 turns in coil 9.

Thus, the winding transitions are located on diametrically opposite sides of it.

The winding of the second coil 9, the third 11 and the fourth 12 is performed similarly to that described, only the last 0.5 turns, in the last coil 12 they are made by wires 3, 4, the number of which is two (m - NA 4 - 1 2), having previously cut two wires (A 2) 1 and 2.

Thus, the end of the winding is made located on two opposite sides of the winding.
