Изобретение относитс к совмещенным обмоткам электрических машин, например одномашинных преобразователей частоты и числа фаз.The invention relates to co-located windings of electric machines, for example, single-machine frequency and phase converters.
По основному авт.св. № 532153 известна трехфазна совмещенна обмотка , содержаща 18 одинаковых катушечныхТ-рупп , соединенных в фазах последовательно , и в фазе группы с номерами 1, 2, 10 и 18 включены согласно, а 3 и 17 - встречно, причем в других фазах группы соединены аналогично со смещением на 6 групп относительно групп соседних фаз.According to the main auth. No. 532153 is a known three-phase combined winding containing 18 identical coil-type T-shirts connected in phases in series, and in phase the groups numbered 1, 2, 10 and 18 are included according to, and 3 and 17 are opposite, and in other phases the groups are connected in a similar way to shift to 6 groups relative to groups of neighboring phases.
Целью изобретени вл етс улучшение использовани меди обмотки.The aim of the invention is to improve the use of copper winding.
Эта цель достигаетс тем, что число витков в катушечных группах с номерами + 3i в два раза больше, чем в остальных группах, где i О, 1,2,...This goal is achieved by the fact that the number of turns in coil groups with numbers + 3i is two times greater than in other groups, where i O, 1,2, ...
На фиг. 1 представлена развернута схема обмотки; на фиг. 2 крива ее Н.С.; на фиг. 3 - звезда ЭДС катушек дл гр - 8 - полюсного ПО.ПЯ; на фиг. 4 - звезда ЭДС дл 2р - полюсного пол .FIG. 1 shows the unwrapped winding scheme; in fig. 2 its NS curve; in fig. 3 - star EMF coils for gr - 8 - pole software. FL; in fig. 4 - EMF star for 2p - pole field.
Число витков в катушках с номерами 1 ,4, 7, 10, 13 И 16 вдвое больше чем в остальных катушках (катушкиThe number of turns in the coils with numbers 1, 4, 7, 10, 13 and 16 is twice that of the other coils (coils
имеют номера от 1 до 18). Крива н,с. (фиг.2) построена по направлени м токов в обмотке (дл момента времени , когда ток в.фазе С1-СА имеет амплитудное значение) и разложена на две встречно вращающиес гармоники с числами полюсов 2р 8 и 2р 4.have numbers from 1 to 18). Curve n, s. (Fig. 2) is built in the direction of the currents in the winding (for the point in time when the current in the C1-CA phase has an amplitude value) and is decomposed into two oppositely rotating harmonics with pole numbers 2p 8 and 2p 4
На звездах ЭДС (фиг.З и 4), где векторам ЭДС приписаны номера катушек , векторы 1,-4, 7, 10, 13 и 16 имеют удвоенную длину, так как катушки с этими номерами имеют вдвое большее число витков по сравнению с остальн лми катушками. Обмоточные коэффициенты такой обмотки равны: К 0,767 дл 2р, 8 и Kgj 0,497 дл 2р 4. Амплитуда 2ру 4 - полюсной гармоники н.с. составл ет 130% от амплитуды основной 2р 8 -полюсной гармоники и произведение Kojg К ОБ 0,381 характеризует использование меди предлагаемой совмещенной обмотки.On the EMF stars (FIGS. 3 and 4), where the EMF vectors are assigned the coil numbers, the vectors 1, -4, 7, 10, 13, and 16 have doubled length, since the coils with these numbers have twice the number of turns compared to the rest lmi coils. The winding coefficients of such a winding are: K 0.767 for 2p, 8 and Kgj 0.497 for 2p 4. The amplitude 2p 4 - pole harmonics h.s. makes up 130% of the amplitude of the fundamental 2p 8 -polar harmonic and the product Kojg KOB 0.381 characterizes the use of copper of the proposed combined winding.
