Description

Дл  преобразовани  частоты переменного тока примен ют статические преобразователи, состо щие из трехобмоточного трансформатора, подключаемого к питающей трехфазной сети, и двух утроителей частоты, присоединенных к двум вторичным обмоткам указанного трансформатора .Static converters consisting of a three-winding transformer connected to a three-phase supply network and two frequency trippers connected to two secondary windings of the specified transformer are used to convert the frequency of an alternating current.

Предлагаемый статический преобразователь более совершенен, так как он обеспечивает получение двухфазной системы напр жений утроенной частоты.The proposed static converter is more perfect, since it provides a two-phase system of voltages of tripled frequency.

Это достигаетс  тем, что одна из вторичных обмоток трансформатора соединена звездой, а друга  - треугольником.This is achieved by the fact that one of the secondary windings of the transformer is connected by a star, and the other is connected by a triangle.

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

Преобразователь состоит из трехфазного трехобмоточного трансформатора / и двух утроителей частоты 2 и 3.The converter consists of a three-phase three-winding transformer / and two frequency terminators 2 and 3.

Одна из обмоток трансформатора / присоединена к питающей трехфазной сети, а две другие обмотки присоединены к утроител м частотыOne of the transformer windings / is connected to the three-phase supply network, and the other two windings are connected to the frequency triples

В каждом утроителе частоты первичные обмотки всех трех сердечников соедин ютс  в звезду и подключаютс  к питающей сети трехфазного тока. Вторичные же обмотки соедин ютс  в открытый треугольник и образуют однофазный выход утроител , на зажимах которого создаетс  напр жение утроенной частоты.In each frequency multiplier, the primary windings of all three cores are connected to a star and connected to a three-phase current supply network. The secondary windings are connected in an open triangle and form a single-phase tripler output, at the terminals of which a voltage of threefold frequency is created.

Дл  получени  двухфазной системы напр жений утроенной частоты вторичные обмотки трансформатора /, питающие утроители соединены одна - звездой, а друга  - треугольником; число витков обмотки, соединенной в треугольник в три раза больще числа витков обмотки, соединенной в звезду.To obtain a three-phase voltage system of threefold frequency, the secondary windings of the transformer /, the supplying triples are connected by one — the star, and the other — by a triangle; the number of turns of the winding connected in a triangle is three times more than the number of turns of the winding connected in a star.

При таком соединении этих обмоток, напр жени  на входах утроителей 2 к 3 равны по амплитудам, но отличаютс  друг от друга по фазе на угол 30°. Напр жени  же тройной частоты на выходах утроителей окажутс  сдвинутыми по фазе на угол 90°.With such a combination of these windings, the voltages at the inputs of the thinners 2 to 3 are equal in amplitude but differ from each other in phase by an angle of 30 °. The triple frequency voltages at the outputs of the triples will be out of phase by an angle of 90 °.
