Abstract

"DISPOSITIVO DE DISPARO ELETROMAGNéTICO E APARELHO DE COMANDO ELéTRICO DE MANOBRA COMPREENDENDO O MESMO". A presente invenção refere-se a um dispositivo de disparo eletromagnético, em particular para um comutador diferencial ou disjuntor de circuito, compreendendo uma armadura em formato de 'U' A, as extremidades da mesma formam duas superfícies polares (7,8), uma palheta (1) pivotante com respeito à armadura A e capaz de ser movida nas ditas superfícies polares (7,8) para fechar o circuito magnético formado pela armadura A e palheta (1), um ímã permanente para polarizar o circuito magnético projetado para prender a palheta nas superfícies polares (7,8), uma bobina de disparo circundando o circuito magnético e capaz de contrabalançar a força do ímã de modo a mover a palheta (1), um pino de reposição (15) da palheta (1), e uma lâmina (10) fixada na palheta (1) projetada para amortecer o impacto das forças de reposição. Este dispositivo de disparo é caracterizado pelo fato de que a lâmina acima mencionada (10) compreende pivós de articulação (25) para articulação da palheta (1) com respeito à armadura A. A lâmina (10) também compreende uma peça na forma de uma trava (30) projetada para permitir o engate de uma mola (9) realizando a orientação da palheta (1) afastada das superfícies polares (7,8) da armadura A contra a ação do ímã permanente."ELECTROMAGNETIC SHOOTING DEVICE AND ELECTRIC HANDLING CONTROL UNDERSTANDING THE SAME". The present invention relates to an electromagnetic triggering device, in particular for a differential switch or circuit breaker, comprising an 'U' A-shaped armature, the ends thereof forming two polar surfaces (7,8), one pivot (1) pivoting with respect to armature A and capable of being moved on said polar surfaces (7,8) to close the magnetic circuit formed by armature A and vane (1), a permanent magnet to polarize the magnetic circuit designed to hold the vane on the polar surfaces (7,8), a firing coil circling the magnetic circuit and capable of counterbalancing the force of the magnet to move the vane (1), a replacement pin (15) of the vane (1), and a blade (10) attached to the vane (1) designed to cushion the impact of replacement forces. This firing device is characterized by the fact that the aforementioned blade (10) comprises pivot pivots (25) for pivoting the blade (1) with respect to armature A. The blade (10) also comprises a piece in the form of a lock (30) designed to engage a spring (9) by orienting the vane (1) away from the polar surfaces (7,8) of armature A against the action of the permanent magnet.
