Description
Насто щее изобретение относитс к способам включени трехфазного двигател в однофазную сеть, согласно которым две обмотки двигател соедин ют своими концами и параллельно им включают цепочку, состо щую из третьей обмотки и последовательно включенного с ней конденсатора, причем параллельно третьей обмотке включают второй конденсатор.The present invention relates to methods for connecting a three-phase motor to a single-phase network, according to which two windings of the motor are connected at their ends and parallel to them include a chain consisting of a third winding and a capacitor connected in series with it, and a second capacitor is connected in parallel with the third winding.
Предлагаемый способ отличаетс от известных тем, что параллельно каждой из двух обмоток электрод&игател , соединенных своими коицами , «включают конденсатор.The proposed method differs from the known ones in that, parallel to each of the two windings, the electrode & amphibians, connected by their coic switches, include a capacitor.
На чертеже изображена схема дл осуществлени предлагаемого способа.The drawing shows a circuit for carrying out the proposed method.
Две фазы В и С обмотки статора трехфазного двигател соедин ютс своими концами последовательно и начала этих фаз подключаютс к однофазной сети. Треть фаза Л соедин етс последовательно с конденсатором Сл и включаетс на сеть таким образом, что конец фазы А присоедин етс к началу одной из двух других фазКажда из трех фаз дополнительно шунтируетс конденсаторами С, С2 и Сз- При соответствующем подборе проводимостей конденсаторов GI, €2 и Сз обеспечиваетс уравновешенный режим (работа с «рутовым полем) при любом коэффициенте мощности нагрузки и при любом режиме {генераторном, двигательном и режиме противовключени ). При этом используютс только реактивиые сопротивлени , что вал но дл уменьшени потерь при преобразовании однофазного тока в трехфазный.The two phases B and C of the stator windings of a three-phase motor are connected at their ends in series and the beginnings of these phases are connected to a single-phase network. The third phase L is connected in series with the capacitor C and is connected to the network in such a way that the end of phase A is connected to the beginning of one of the two other phases. Each of the three phases is additionally bridged by capacitors C, C2 and C3. With appropriate selection of the conductivities of GI capacitors, € 2 and Sz is provided with a balanced mode (operation with a "rutovy field) for any load power factor and for any mode {generator, motor and opposition mode). In this case, only reactive resistances are used, which is, however, the shaft, but in order to reduce losses in the conversion of single-phase current into three-phase current.
Предмет изобретени Subject invention
Способ включени трехфазного двигател в однофазную iceTb, по которому две обмотки двигател соедин ют своими концами и параллельно им включают цепочку, состо щую из третьей обмотки н последовательно включенного с ней конденсатора, а параллельно указанной третьей обмотке включают второй конденсатор, отличаюш,ийс тем, что, с целью отдачн реактивной моодностн в сеть при уравновешенной работе , нараллельно каждой из двух обмоток, соединенных своими концами, включают конденсатор.The method of switching a three-phase motor into a single-phase iceTb, in which two motor windings are connected at their ends and parallel to them include a chain consisting of a third winding and a capacitor connected in series with it, and a second capacitor parallel to said third winding is distinguished by the fact that In order to return the reactive power to the network during balanced operation, in parallel with each of the two windings connected by their ends, include a capacitor.
