Abstract
Устройство переключения отводов обмотки трансформатора, содержащее преобразовательный трансформатор с отводами пониженного и повышенного напряжений, последовательно с которыми включены тиристоры, причем одна пара тиристоров подключена одними выводами к отводам пониженного напряжения ветвей расщепленной обмотки, а другая - к отводам повышенного напряжения, выводы питания нулевой и фазный, цепи управления «Ниже» и «Выше», триггер, входы которого соединены с цепями управления, а выходы - через согласующие элементы присоединены к управляющим электродам, отличающееся тем, что трансформатор имеет две ветви расщепленной обмотки с отводами пониженного и повышенного напряжений, тиристоры объединены в две вентильные группы противоположных направлений электропроводности, двумя выводами соединенные друг с другом и с фазным выводом цепи питания, причем вентильная группа одного направления электропроводности другими выводами подключена к отводам одной ветви расщепленной обмотки, а вентильная группа противоположной электропроводности - к отводам другой ветви расщепленной обмотки.A device for switching the taps of a transformer winding, comprising a converter transformer with taps of low and high voltage, with which the thyristors are connected in series, one pair of thyristors being connected by one terminal to the low voltage taps of the branches of the split winding, and the other to the high voltage taps, the power leads are zero and phase , control circuits “Below” and “Above,” a trigger whose inputs are connected to control circuits, and the outputs, through matching elements, are connected to the control characterized by the fact that the transformer has two branches of a split winding with low and high voltage taps, the thyristors are combined into two valve groups of opposite directions of electrical conductivity, two leads connected to each other and with a phase output of the power circuit, and the valve group of one direction of electrical conductivity by others leads connected to the taps of one branch of a split winding, and the valve group of the opposite conductivity to the taps of another branch of a split bmotki.
