Изобретение относится к области электротехники, в частности к источникам питания электродуговых, индукционных и сварочных установок, и может быть использовано в преобразовательной технике в качестве регуляторов напряжения или тока, вольтодобавочных трансформаторов и стабилизаторов напряжения и тока. Регулируемый трансформатор содержит трехстержневой магнитопровод с двумя первичными обмотками на крайних стержнях и одной вторичной обмоткой, размещенной на каждом стержне, и регулирующее устройство, соединенное со схемой управления, которая подключена через фазосдвигающее устройство к вспомогательной обмотке. Первичные обмотки соединены параллельно и подключены к питающей сети, причем одна из них подключена через регулирующее устройство, совместно с другой на стержне введена вспомогательная обмотка, а части вторичной обмотки между собой соединены согласно-последовательно. Питающая сеть может быть однофазной или трехфазной. В предлагаемом трансформаторе решаются задачи повышения энергетических показателей и надежности работы, снижения массы, габаритов, стоимости и уровня радиопомех, расширения функциональных возможностей.The invention relates to the field of electrical engineering, in particular to power sources of electric arc, induction and welding installations, and can be used in converter equipment as voltage or current regulators, booster transformers and voltage and current stabilizers. An adjustable transformer contains a three-core magnetic core with two primary windings on the outermost rods and one secondary winding placed on each rod, and a regulating device connected to the control circuit, which is connected via a phase shifter to the auxiliary winding. The primary is connected in parallel and connected to the supply network, one of which is connected via a regulating device, an auxiliary winding is inserted on the rod together with the other, and the parts of the secondary winding are interconnected. The mains supply can be single phase or three phase. The proposed transformer solves the problem of increasing energy performance and reliability, reducing weight, size, cost and level of radio interference, expanding functionality.
