Abstract

<B>TRANSFORMADOR DE FORçA DE CABO ENROLADO E MéTODO DE RESFRIAMENTO A AR DO MESMO<D>. Um transformador de força (1) compreendendo um núcleo de transformador enrolado com um cabo de alta tensão, o qual é composto de um núcleo tendo várias partes de fios (112), uma camada interna semicondutora (113) envolvendo o núcleo, uma camada isolante (114) envolvendo a camada interna semicondutora (113), e uma camada externa semicondutora (115) envolvendo a camada isolante (114) em que o enrolamento é munido de espaçadores (4, 12) dispostos para separar cada espira de cabo na direção radial no enrolamento com a finalidade de criar ductos axiais cilíndricos de esfriamento (3).<B> WIRED CABLE FORCE TRANSFORMER AND AIR COOLING METHOD OF THE SAME <D>. A power transformer (1) comprising a transformer core wrapped with a high voltage cable, which is composed of a core having several parts of wires (112), an inner semiconductor layer (113) surrounding the core, an insulating layer (114) involving the inner semiconductor layer (113), and an outer semiconductor layer (115) surrounding the insulating layer (114) in which the winding is provided with spacers (4, 12) arranged to separate each cable loop in the radial direction in the winding in order to create cylindrical axial cooling ducts (3).
