Description
(5t) ПРЕОБРАЗОВАТЕЛЬ ТРЕХФАЗНОГО ПЕРЕМЕННОГО НАПРЯЖЕНИЯ В ПОСТОЯННОЕ(5t) THREE-PHASE AC VOLTAGE CONVERTER TO PERMANENT
Изобретение относитс к преобразовательной технике и может быть использовано дл питани мощных потребителей , требующих небольшого диапазона- регулировани подводимого напр жени ) .The invention relates to a converter technique and can be used to power high-power consumers requiring a small range (voltage regulation).
Известен преобразователь трехфазного переменного напр жени в посто нное, в котором регулирование осуществл етс на стороне переменного тока 13. .A three-phase alternating-voltage-to-constant voltage converter is known, in which regulation is carried out on the alternating-current side. 13..
Однако такой преобразователь не может быть использован при больших мощност х. .However, such a converter cannot be used at high power. .
Наиболее близким к предлагаемому вл етс преобразователь трехфазного переменного напр жени в посто нное , содержащий основной трехфазный трансформатор, первичные обмотки которого соединены в треугольник , а вторичные - в звезду,причем вторичные обмотки подключены к диагонали переменного тока трехфаз1ног6 выпр мительного моста, диаго- iThe closest to the present invention is a three-phase alternating voltage converter into a constant voltage, containing a main three-phase transformer, the primary windings of which are connected in a triangle and the secondary windings in a star, and the secondary windings are connected to the diagonal of an alternating current of a three-phase rectifier bridge, dia- i
наль посто нного тока которого под:клk}чeнa к выходным зажимам, и три однофазных трансформатора, вторичные обмотки которых включены в соответствующие фазные цепи между входными выводами и первичными обмотками основного трансформатора, а первичные обмотки соединены в звезду, фазные выводы которой через тиристорные ключи подключены к фазным . the direct current of which is under: CLK} to the output terminals, and three single-phase transformers, the secondary windings of which are included in the corresponding phase circuits between the input terminals and the primary windings of the main transformer, and the primary windings are connected to the star, the phase outputs of which are connected through the thyristor switches to phase.
10 входным выводам, а обща точка - к общему входному выводу 2.10 input pins, and a common point - to a common input pin 2.
Недостатком известного преобразовател вл етс низка надежность из-за больших перенапр жений на тиts ристорнмх ключах.A disadvantage of the known converter is the low reliability due to large overvoltages on the type of the resistor keys.
Целью изобретени вл етс повышение надежности.The aim of the invention is to increase reliability.
Поставленна цель достигаетс тем, что в пpeoбpaзoвateлe трехфазного The goal is achieved by the fact that in a three-phase transducer
