Description

Дл  преобразовани  однофазной системы напр жени  в симметричную трехфазную систему примен ют трехобмоточные трансформаторы с двум  вторичными обмотками, к которым подключаетс  трехфазна  нагрузка .Three-winding transformers with two secondary windings, to which a three-phase load is connected, are used to convert a single-phase voltage system into a symmetrical three-phase system.

Предлагаемый преобразователь отличаетс  от известных применением в нем фазосдвигаюп1его индуктивно-омического моста. Такое выполнение преобразовател  упрощает его схему и настройку и позвол ет осуществить как преобразование однофазного напр жени  в симметричную трехфазную систему напр жений , так и преобразование трехфазной системы напр жений в однофазную.The proposed converter is different from those known for using a phase-shifting inductive-ohmic bridge in it. This embodiment of the converter simplifies its design and configuration and allows for the conversion of a single-phase voltage into a symmetrical three-phase voltage system, as well as a conversion of a three-phase voltage system into a single-phase one.

На чертеже изображена принципиальна  схема предлагаемого преобразовател .The drawing shows a schematic diagram of the proposed Converter.

Преобразователь выполнен в виде трехобмоточного трансформатора с первичной (однофазной) обмоткой / и двум  вторичными обмотками 2 и 3.The Converter is made in the form of a three-winding transformer with a primary (single-phase) winding / and two secondary windings 2 and 3.

От вторичной обмотки 2 питаетс  мостова  схема, состо ща  из двух активных 4 и 5 и двух реактивныхA secondary circuit is fed from the secondary winding 2, consisting of two active 4 and 5 and two reactive

6сопротивлений,  вл юнднхс  четырьм  плечами фазосдвигающего места.6 resistances, vl yndnkhs four arms of the phase-shifting place.

Трансформатор имеет коэффициент трансформации, равный единице, и включаетс  в схему таким образом , что ампер-витки его обеих обмоток складываютс .The transformer has a transformation ratio of one and is included in the circuit in such a way that the ampere turns of its two windings add up.

Вторична  обмотка 3 совместно с двум  фазами трехфазной нагрузкиSecondary winding 3 together with two phases of three-phase load

Параметры фазосдвигающего моста подбираютс  так, чтобы обеспечивалс  требуемый сдвиг фаз между напр жени ми на обмотках 2 и 3 трансформатора, необходимый дл  получени  трехфазной системы напр жений .The parameters of the phase-shifting bridge are selected so as to ensure the required phase shift between the voltages on the windings 2 and 3 of the transformer necessary to obtain a three-phase voltage system.
