Abstract

Силовой трансформатор (1) содержит трансформаторный сердечник, обмотанный высоковольтным кабелем (111), который состоит из сердцевины, имеющей множество жил (112), внутреннего полупроводящего слоя (113), окружающего сердцевину, изолирующего слоя (114), окружающего внутренний полупроводящий слой (113), и внешнего полупроводящего слоя (115), окружающего изолирующий слой (114), причем обмотка снабжена разделителями (4, 12) для разделения всех витков кабеля в обмотке в радиальном направлении, чтобы создать осевые цилиндрические каналы (3) охлаждения.Международная заявка была опубликована вместе с отчетом о международном поиске.The power transformer (1) contains a transformer core wrapped with a high-voltage cable (111), which consists of a core having many wires (112), an inner semiconducting layer (113) surrounding the core, an insulating layer (114) surrounding the inner semiconducting layer (113 ), and the outer semiconducting layer (115) surrounding the insulating layer (114), and the winding is equipped with separators (4, 12) to separate all turns of the cable in the winding in the radial direction to create axial cylindrical cooling channels (3). This application was published with the international search report.
