Изобретение относитс к технологии, изготовлени оонрхоаовьи винтовых обмоток трансформаторов и может 6t}iTb использовано в электротехнической промышленности.The invention relates to the technology of manufacturing single-screw screw windings of transformers and can 6t} iTb used in the electrical industry.

Известен способ намотки одаоходовой винтовой обмотки трансформатора, включающий последовательную намотку витков с разделением проводов в ради . альном направлении на ове группы, которые мен ют местами после перекладки их в двух пол х, и выполнением перёходов проводов одной Труппы и через иоле - другой LI. . ,There is a method of winding the winding screw winding of the transformer, including the sequential winding of the turns with the separation of wires in the sake. In the opposite direction, on the OV, the groups that are reversed after being transferred in two fields, and by performing wire crossovers of one Group and, through iol, the other LI. . ,

Однако известный способ намотки пр№одит к увеличению высогы обмотки за счет выполнени двух групповых (специальных ) и одной (стандартной) транспозиции .. ; Целью изобретени вл etc уменьшение высоты обмотки и увеличение коэффициента заполнени окна магнито провода.However, the known winding method increases the height of the winding by performing two group (special) and one (standard) transposition ..; The aim of the invention is to reduce the height of the winding and increase the filling ratio of the magnetic window.

Поставленна пель достигаете тем, , что проводами первой группы выполн ют один виток, затем укладьтают на них провода второй группы и одновременную намотку обеих групп .производ т с отставанием второй группы от первой на ощш виток.The delivered pellet is achieved by carrying out one turn of wires of the first group, then laying the wires of the second group on them and simultaneously winding both groups. The second group is lagging behind the first group from the first turn.

На фиг. 1 изображена развертка обмотки, где стрелками показаны мес10 та перекладки проводов; на фиг. 2 показана последовательность выполнени способа.FIG. Figure 1 shows a winding sweep, where the arrows indicate the month of wire transfer; in fig. 2 shows the sequence of the method.

Обмотка намотана из i шести витков, сечениекаждого из которых состоит The winding is wound from i six turns, each section of which consists of

is из шести параллельных проводов 1-6, Которые дел т на две группы, в первую из указанных групп вход т провода 1-3, а во вторую - провода 4-6. Проводами первой группы наматывают It consists of six parallel wires 1-6, which are divided into two groups, the first of the specified groups consists of wires 1-3, and the second - wires 4-6. The wires of the first group are wound

Claims

20 one winding, the second bundle of wires is laid in it in the radial direction, then the crossings between the wires of both groups are performed, as well as the winding. coils are performed in the following sequence. G cycle. The wire I, located at the beginning of the BTof) oro turn of the first group, is shifted to the place of the wire 4, located at the beginning of the first turn of the second group. The wire 6, located at the beginning of the first turn of the second group, is shorted into place of the wire 3, located at the beginning of the second turn of the First group. Wires 4 and 5, located at the beginning of the first coil of the second group, and wires 3 and 2, located at the beginning of the second coil of the first group, ("responsibly move up and down radially, after which all parallel wires of both groups wind one turn by forming the first turn of the full cross section and the second turn by wires 2, 3, 6. ii .; cycle. Similarly to the first cycle, wires 2 and 5 are transferred from one group to another, radially wires 1, 4 and 6, 3 are moved, winding the second turn. W. cycle. Similarly to the second cycle, wires 3 and 4 are shifted, wires 2, 1 and 5, 6 are placed, winding the third coil L. cycle: wires 6 and 1 are shifted similarly to the second cycle, wires 3,2 and 4,5 are shifted, and the fourth loop is shifted. and 2, moves wires 6.3 and 1.4, winds the fifth turn,, cycle .. Similarly to the second cycle, move wires 4 and 3, move wires 5.6 and 2.1, wires 1-3 located at the end of the sixth loop the first group, cut and wound with wires 4-6 of the sixth round. Likewise, a single-screw screw winding consisting of any combination of wires, even or odd, can be wound. The described method of winding a one-way screw winding of a transformer, consisting, for example, of a twist coil wound by six parallel wires, makes it possible to reduce the height (axial dimension) of the winding to the height of three turns and three channels. Claims The method of winding a one-way screw winding of a transformer, according to which sequential winding of turns is carried out with separation of wires in the radial direction into two groups and making transitions between them in different fields, characterized in that, in order to reduce the height of the winding, and increase the fill factor magnetic conductor windows, one turn is made with wires of the first group, then the wires of the second group are laid on them and simultaneous winding of both groups is performed with the second group lagging so the first one round.
