Abstract

EL ELEMENTO LIMITADOR DE CORRIENTE SE COMPONE DE UN CUERPO DE RESISTENCIA ELECTRICA (3) DISPUESTO ENTRE DOS CONEXIONES DE CONTACTO (1,2). ESTE CUERPO DE RESISTENCIA ELECTRICA (3) CONTIENE UN PRIMER MATERIAL RESISTENTE QUE PRESENTA COMPORTAMIENTO PTC. POR DEBAJO DE UNA TEMPERATURA LIMITE POSEE EL PRIMER MATERIAL RESISTENTE UNA PEQUEÑA RESISTENCIA ESPECIFICA EN FRIO Y POR LO MENOS UN CIRCUITO CONDUCTOR DE CORRIENTE QUE DISCURRE ENTRE LAS CONEXIONES DE CONTACTO (1,2). POR ENCIMA DE LA TEMPERATURA LIMITE POSEE EL PRIMER MATERIAL RESISTENTE UNA GRAN RESISTENCIA ESPECIFICA EN CALIENTE COMPARADA CON SU RESISTENCIA ESPECIFICA EN FRIO. UN ELEMENTO LIMITADOR DE CORRIENTE DE ESTA CLASE, SE DEBE DESTACAR, A PESAR DE SU CONSTITUCION SENCILLA Y DE COSTES FAVORABLES, POR LA CAPACIDAD DE CONEXION HOMOGENEA Y ELEVADA CAPACIDAD PORTANTE DE CORRIENTE NOMINAL. ESTO SE ALCANZA PORQUE EL CUERPO DE RESISTENCIA ELECTRICA (3) CONTIENE ADICIONALMENTE UN SEGUNDO MATERIAL DE RESISTENCIA CON UNA RESISTENCIA ESPECIFICAQUE ESTA SITUADA ENTRE LA RESISTENCIA ESPECIFICA EN FRIO Y LA RESISTENCIA ESPECIFICA EN CALIENTE DEL PRIMER MATERIAL DE RESISTENCIA, Y PORQUE EL SEGUNDO MATERIAL DE RESISTENCIA ESTA PUESTO EN CONTACTO ELECTRICO INTIMO CON EL PRIMER MATERIAL DE RESISTENCIA Y POR LO MENOS FORMA UNA RESISTENCIA CONECTADA EN PARALELO CON AL MENOS UNA SECCION PARCIAL DE POR LO MENOS UN CIRCUITO CONDUCTOR DE CORRIENTE.
