Abstract

Трансформатор или реактор содержит сердечник и, по меньшей мере, одну обмотку, сердечник (1; 11; 21; 31) включает, по меньшей мере, два сегмента (4; 14; 24, 25; 33, 34, 36, 37), а обмотка является гибкой и содержит электропроводящую сердцевину (7), окруженную внутренним полупроводящим слоем (8), изолирующий слой (9), окружающий внутренний полупроводящий слой и выполненный из твердого материала, и внешний полупроводящий слой (10), окружающий изолирующий слой, причем упомянутые слои соединены друг с другом.Международная заявка была опубликована вместе с отчетом о международном поиске.The transformer or reactor contains a core and at least one winding, the core (1; 11; 21; 31) includes at least two segments (4; 14; 24, 25; 33, 34, 36, 37), and the winding is flexible and comprises an electrically conductive core (7) surrounded by an inner semiconducting layer (8), an insulating layer (9) surrounding the inner semiconductive layer and made of a solid material, and an outer semiconductive layer (10) surrounding the insulating layer layers are interconnected. The international application was published along with a report on international search.
