Abstract

Трансформаторный сердечник содержит, по меньшей мере, один стержень и одну перемычку, причем поперечное сечение стержня или стержней имеет форму правильного многоугольника с числом сторон, большим четырех. Сердечник изготовлен из колец, навитых из лент постоянной ширины, благодаря чему обеспечиваются хорошие электрические свойства. Трансформатор прост в изготовлении, при этом сокращаются отходы материала.Международная заявка была опубликована вместе с отчетом о международном поиске.The transformer core contains at least one rod and one jumper, with the cross section of the rod or rods having the shape of a regular polygon with more than four sides. The core is made of rings wound from ribbons of constant width, which ensures good electrical properties. The transformer is easy to manufacture, while reducing material waste. The international application was published along with an international search report.
