Abstract

TRANSFORMADOR COM BLINDAGEM ELÉTRICA. A presente invenção refere-se a um transformador em particular, transformador de resina de fundição com, pelo menos, um enrolamento de baixa tensão e, pelo menos, um enrolamento de alta tensão. Por meio da disposição de uma blindagem elétrica em torno do enrolamento de alta tensão, é evitada uma descarga disruptiva da tensão de tal modo que a parede externa do transformador pode ser tocada por uma pessoa e, por outro lado, assegura uma blindagem eletromagnética do transformador. Por meio do emprego de passagens para as conexões elétricas que ficam internas é possível a instalação do transformador de acordo com a invenção em ambientes suscetíveis à sujeira e ao ar livre.
