Abstract

TRANSFORMADOR COMPREENDENDO UM CONJUNTO DE BOBINA E BLINDAGEM ELÉTRICA PARA UM TRANSFORMADOR DO TIPO SECO E MÉTODO PARA FABRICAR UM CONJUNTO DE BOBINA E BLINDAGEM ELÉTRICA PARA UM TRANSFORMADOR. A invenção refere-se à blindagem de enrolamentos de um transformador, em particular a um conjunto de bobina e blindagem elétrica para um transformador, um transformador com o conjunto e um método para fabricar um conjunto de bobina e blindagem elétrica para um transformador. É fornecido um conjunto de bobina e blindagem elétrica (200) para um transformador do tipo seco, em que um dispositivo de blindagem elétrica (120, 204) é disposto a uma distância (D1, D2) para um enrolamento (103, 202) em uma extremidade axial (116, 118) do enrolamento (103, 202) perpendicular a um eixo geométrico longitudinal (A) do transformador e paralelo à superfície de topo de uma bobina de forma cilíndrica que é enrolada pelo enrolamento (103, 202) em volta do eixo geométrico (A) de modo que o dispositivo de blindagem elétrica (120, 204) cubra a área de seção transversal do enrolamento (103, 202) perpendicular ao eixo geométrico longitudinal (A). Outro destes dispositivos de blindagem elétrica (120, 204) pode ser disposto na outra extremidade axial do enrolamento (103, 202). Um material de isolamento (201) é fixado ao enrolamento (103, 202) e ao dispositivo de blindagem elétrica (120, 204) fornecendo a distância (D1, D2) entre o enrolamento (103, 202) e o dispositivo de blindagem elétrica (120, 204) ao longo do eixo geométrico longitudinal (A) de modo que um ambiente do enrolamento (103, 202) seja blindado contra o campo elétrico do enrolamento (103, 202). O enrolamento (103, 202) e o dispositivo de blindagem elétrica (120, 204) são fundidos em um bloco que isola o dispositivo de blindagem elétrica (120, 204) do campo elétrico do enrolamento (103, 202) fornecendo uma distância entre o enrolamento (103, 202) e o dispositivo de blindagem elétrica (120, 204).
