Abstract

sistema de isolamento elétrico (1) para dispositivo de indução eletromagnética de alta-tensão (18) que compreende um bastão (3) que possui duas porções laterais (7, 9) e uma porção central elevada (5) que é elevada em relação à e disposta entre as duas porções laterais (7, 9). a porção central elevada (5) define uma superfície faceadora de enrolamento (5a) disposta para facear um enrolamento (19), o bastão (3) possui uma superfície de contato com barreira (13) oposta à superfície faceadora de enrolamento (5a), no qual a primeira distância entre a superfície faceadora de enrolamento (5a) e a superfície de contato da barreira (13) define a espessura t do bastão (3) que possui uma primeira ranhura (11a) entre uma primeira porção lateral (7) das duas porções laterais (7, 9) e a porção central elevada (5), e uma segunda ranhura (11b) entre uma segunda porção lateral (9) das duas porções laterais (7, 9) e a porção central elevada (5), primeira e a segunda ranhuras (11a, 11b) que se estendem axialmente ao longo do bastão (3), no qual cada uma dentre a primeira e a segunda porções laterais (7, 9) possui uma respectiva superfície de ranhura adjacente (7a, 9a) oposta à superfície de contato da barreira (13), no qual uma segunda distância t1 a partir de cada superfície de ranhura adjacente (7a, 9a) até um plano (p1) definido pela superfície faceadora de enrolamento (5a) satisfaz a relação t1<0,6t. a presente invenção também refere-se a um dispositivo de indução eletromagnética de alta-tensão que compreende o sistema de isolamento elétrico.
