Abstract

"FUSìVEL ENCAPSULADO COM BLINDAGEM DE CORONA". A invenção refere-se a um fusível encapsulado (10) para os sistemas de distribuição de energia e um método para produzir tais fusíveis. Um fusível inclui um corpo (20) com terminais (30, 40) opostos. Uma blindagem de corona (50) é geralmente coaxial com o fusível (10) e substancialmente estende-se pelo comprimento inteiro do corpo de fusível (20). A blindagem de corona (50) está eletricamente acoplada na sua primeira extremidade (70) com um primeiro terminal de fusível (30). A segunda extremidade (80) da blindagem de corona (50) tem uma seção transversal ligeiramente maior do que a primeira extremidade (70) para prover um isolamento elétrico do segundo terminal de fusível (40). O fusível (10) e a blindagem de corona (50) montada são moldados em um material de encapsulamento (150).
