Abstract

EL CONVERTIDOR DE CORRIENTE DE NUCLEO ANULAR CONTIENE AL MENOS UN NUCLEO (4, 5, 6) ANULAR DISPUESTO DENTRO DE UN BLINDAJE (7, 8), PREVISTO CON ARROLLAMIENTO (1, 2, 3) SECUNDARIO. EN LA ABERTURA DEL NUCLEO (4, 5, 6) ANULAR DISCURRE UN CONDUCTOR (9) PRIMARIO. ENTRE EL NUCLEO (4, 5, 6) ANULAR Y EL CONDUCTOR (9) PRIMARIO SE DISPONE DE UN TUBO (10) INTERIOR AISLADO ELECTRICAMENTE EN EL EXTREMO CON EL BLINDAJE (8) INTERNO ELECTRICO UNIDO DE FORMA CONDUCTORA EN LOS LUGARES RESTANTES AISLADOS ELECTRICAMENTE Y UN BLINDAJE (8) INTERIOR ENTRE LOS LUGARES DE UNION ELECTRICOS INTERNOS, ASI COMO EL LADO CORRESPONDIENTE AL TUBO (10) INTERIOR EN EL NUCLEO (4, 5, 6) ANULAR UNIDO CON EL BLINDAJE (7) EXTERIOR DE FORMA CONDUCTORA ELECTRICA DIRECTA, DE TAL MODO QUE SE HA PREVISTO QUE EL TUBO (10) INTERIOR SE SOLAPE PARCIALMENTE CON UNA CAPA CONDUCTORA ELECTRICA. SOBRE EL TUBO (10) INTERIOR SE ENROLLA AL MENOS UNA CAPA AISLANTE, QUE SE APOYA SOBRE LA CAPA CONDUCTORA ELECTRICA, DE TAL MODO QUE SOBRE EL TUBO (10)INTERIOR SE DISPONE DE UN CONDENSADOR (11) ARROLLADO PARA LA CONDUCCION DE NUEVO NO IMPEDIDA DE ACUERDO CON LAS ONDAS HELICOIDALES EN UNA CAPACIDAD SUFICIENTE. EL CONDENSADOR (11) ELABORABLE DE FORMA SENCILLA PUEDE SER DE UNA O DE MULTIPLES CAPAS.
