Abstract

CONVERTIDOR (10) DE CORRIENTE CON UN CONDUCTOR QUE FORMA UN LAZO (11) CONDUCTOR EN FORMA DE U, ALOJADO AL MENOS EN LAS PROXIMIDADES DE UN PLANO, SIENDO RECORRIDO POR LA CORRIENTE A SER MEDIDA, Y EN CUYO INTERIOR ESTA DISPUESTA UNA ESPIRA (13) CONECTABLE A UN CONTADOR DE ELECTRICIDAD ELECTRONICO, CUYO ARROLLAMIENTO DESCANSA DE FORMA PARALELA CON RESPECTO AL PLANO DEL LAZO (11) CONDUCTOR. EL LAZO (11) CONDUCTOR Y LA ESPIRA (13) ESTAN CERCADOS POR UNA CUBIERTA ACTIVA DE APANTALLADO A BASE DE MATERIAL CONDUCTOR MAGNETICO, ALCANZANDOSE UN MONTAJE DE CONSTRUCCION SENCILLA Y CON ALTA ESTABILIDAD DURANTE LARGO TIEMPO EN SERVICIO, CUANDO DE ACUERDO CON LA INVENCION, LA CUBIERTA MAGNETICA BLANDA ESTA CONFIGURADA A TRAVES AL MENOS DE UN ELEMENTO (14) EN FORMA DE LAMINAS PLANAS, CUYO PLANO SE ENCUENTRA AL MENOS APROXIMADAMENTE VERTICAL CON RESPECTO AL PLANO DEL LAZO (11) CONDUCTOR.
