Abstract

resumo “atuador eletromagnético” a presente invenção relaciona-se a um atuador eletromagnético para operar pelo menos um contato móvel de um disjuntor para uma posição ligada ou posição desligada sendo que o atuador eletromagnético compreende um corpo de polo estático; um corpo de polo móvel em relação ao corpo de polo estático; um primeiro circuito magnético compreendendo uma primeira bobina para aproximar o corpo de polo móvel do corpo de polo estático para a posição ligada, e uma segunda bobina para afastar o corpo de polo estático do corpo de polo móvel para a posição desligada; e um segundo circuito magnético compreendendo um magneto permanente e placa de retenção, para manter o corpo de polo estático e o corpo de polo móvel na posição ligada; um primeiro meio de mola para pressionar para afastar o corpo de polo estático do corpo de polo móvel; e sendo que os primeiro e segundo circuitos magnéticos são arranjados concentricamente. 1/1
