где Sк з - сечение сверхпроводящей обмотки; W2 - число витков вторичной обмотки; Jк р -критическая плотность тока; Iс т - ток стабилизации на выходе трансформатора; K - коэффициент, зависящий от числа витков, схемы соединения обмоток и геометрических размеров магнитопровода и обмоток (K=1,5oC3). Криостат трансформатора может быть выполнен подвижным и неподвижным. С целью получения малого объема, внутрь криостата помещают или подвижную обмотку, или неподвижные обмотки, или все обмотки вместе.The invention relates to the field of electrical engineering, induction devices, transformers. The purpose of the invention is to reduce energy losses in transformers with a smooth voltage regulation, reduction of short circuit current, stabilization of the load current. The transformer contains a magnetic core, fixed windings, a movable short-circuited winding, which is made of a solid superconducting material and placed in a cryostat with a cooling fluid having a temperature below the critical one for the superconducting material. The cross section of a short-circuited winding is determined by the formula
where S to s - the cross section of the superconducting winding; W 2 - the number of turns of the secondary winding; J to p is the critical current density; I with t - current stabilization at the output of the transformer; K is a coefficient depending on the number of turns, the connection scheme of the windings and the geometric dimensions of the magnetic core and windings (K = 1.5 o C3). The transformer cryostat can be made movable and stationary. In order to obtain a small volume, either a moving winding, or fixed windings, or all the windings are placed inside the cryostat.
