Abstract

UN RESISTOR CAPAZ DE ACTUAR COMO DISYUNTOR. UN APARATO Y UN METODO POR EL CUAL INTENCIONADAMENTE SE HACE QUE UN RESISTOR TIPO FILAMENTO PLANO (10) SE FRACTURE POR CHOQUE TERMICO (1) EN RESPUESTA A UN ESTADO DE SOBRECARGA DE ALTA TENSION PREDETERMINADO. EL RESISTOR INCLUYE RECUBRIMIENTOS DE RESISTOR TIPO FILAMENTO PLANO (28, 29) CONECTADOS A TRAZAS (16, 18, 52). SE MONTA UN ALAMBRE DE MUELLE DE TENSION (71, 72) EN DICHO RESISTOR TIPO FILAMENTO Y SE CONECTA EN CIRCUITO CON EL. SE UTILIZAN UNA SOLDADURA (76) Y UN GRADIENTE DE TEMPERATURA PREDETERMINADOS PARA FIJAR EL MUELLE EN ESTADO DOBLADO HASTA QUE SE FUNDA LA SOLDADURA (76), DESPUES DE LO CUAL EL MUELLE (71, 72) SE DOBLA Y EL CIRCUITO SE ABRE. SE FACILITAN LAS PARTES DE DISIPADOR TERMICO (43-46) EN LA PLACA DEL CIRCUITO PARA DICHO RESISTOR Y LAS CLAVIJAS DE RECEPCION (33-40) DEL MISMO.
