Abstract

LA PRESENTE INVENCION SE REFIERE A UN MECANISMO DE ACCIONAMIENTO DEL CONTACTO MOVIL DE UNA CAMARA DE CORTE (1) DE PROTECCION INSTALADA SOBRE UNA LINEA ELECTRICA DE ALTA O MEDIA TENSION Y QUE DEBE ESTAR ABIERTA PARA LA APARICION DE UN UMBRAL DE SOBREINTENSIDAD SOBRE LA LINEA, COMPRENDIENDO ESTE MECANISMO UN ORGANO MOTOR QUE ARRASTRA UN DISPOSITIVO DE DESPLAZAMIENTO (5) DEL CONTACTO. EL ORGANO MOTOR ES UN MUELLE HELICOIDAL (5) CONDUCTOR DE ALEACION CON MEMORIA DE FORMA UNIDO ELECTRICAMENTE A LA LINEA Y CUYO CALENTAMIENTO, CUANDO ES ATRAVESADO POR DICHO UMBRAL DE SOBREINTENSIDAD, ES TAL QUE DICHA ALEACION PASA DE SU FASE MARTENTISICA A SU FASE AUSTENITICA Y PERMITE EL RECIERRE DE LA CAMARA DE CORTE (1) GRACIAS A UN DISPOSITIVO SECUENCIADOR (8) ASOCIADO AL DISPOSITIVO DE DESPLAZAMIENTO (5) Y QUE ASEGURA UN CICLO AJUSTABLE Y TEMPORIZADO DE ABERTURAS Y D CIERRES.
