Abstract

METODO Y DISPOSITIVO PARA PROTEGER CIRCUITOS CONTRA CAMBIOS EN LAS CONDICIONES DE FUNCIONAMIENTO, EN DONDE EL METODO COMPRENDE CONECTAR EN SERIE CON EL CIRCUITO A PROTEGER UN AISLADOR NORMALMENTE CONDUCTOR Y PONER UN DISPOSITIVO DE COEFICIENTE DE TEMPERATURA POSITIVO (DISPOSITIVO DE PTC) EN COMUNICACION TERMICA CON UN ELEMENTO FUSIBLE DEL AISLADOR Y CON UN DISIPADOR DE CALOR DE TAL MANERA QUE, EN FUNCIONAMIENTO NORMAL, LA GENERACION DE CALOR EN EL DISPOSITIVO DE PTC IGUALE LA PERDIDA DE CALOR EN EL DISIPADOR Y, AL PRODUCIRSE UNA VARIACION POTENCIALMENTE PERJUDICIAL DEL FUNCIONAMIENTO, LA GENERACION DE POTENCIA EN EL DISPOSITIVO DE PTC REBASE LA PERDIDA DE CALOR Y AUMENTE RAPIDAMENTE HASTA FUNDIR DICHO ELEMENTO. EL DISPOSITIVO PROTECTOR INCLUYE DICHO AISLADOR CON SU ELEMENTO FUSIBLE Y DICHO DISPOSITIVO DE PTC COMUNICADO TERMICAMENTE CON DICHO ELEMENTO. EL INVENTO ES APLICABLE PARTICULARMENTE A APARATOSELECTRODOMESTICOS.
