Abstract

UN PANEL CALENTADO ELECTRICAMENTE, TAL COMO UNA MANTA ELECTRICA, COMPRENDE UN ELEMENTO TERMICO ELECTRICO QUE COMPRENDE CONDUCTORES DE BOBINA COAXIAL INTERNO Y EXTERNO (R1, R2) SEPARADOS POR UNA CAPA ELECTRICAMENTE AISLANTE (10), UN PRIMER DIODO DE RECTIFICACION (D1) SOBRE LA MANTA ELECTRICAMENTE CONECTADA EN SERIE ENTRE LOS CONDUCTORES Y UN CONJUNTO DE CONTROL AJUSTABLE (12) PARA SU CONEXION A UNA FUENTE DE ALIMENTACION PRINCIPAL DE CORRIENTE ALTERNA Y CONECTADO AL ELEMENTO TERMICO POR UN CABLE ELECTRICO FLEXIBLE DE DOS ALMAS (11=. EL CONJUNTO DE CONTROL INCORPORA UN DISPOSITIVO DE CONTROL, TAL COMO UN SCR (S1), PARA VARIAR LA ALIMENTACION DE CORRIENTE AL ELEMENTO TERMICO, UN FUSIBLE ACCIONADO TERMICAMENTE (F1), UN SEGUNDO DIODO DE RECTIFICACION (D2), Y UNA RESISTENCIA (R3) SITUADA ADYACENTE AL FUSIBLE (F1) Y CONECTADO ENTONCES AL SEGUNDO DIODO (D2) QUE EN CASO DE CORTOCIRCUITO DEL PRIMER DIODO (D1), , COMO RESULTADO DE UN SOBRECALENTAMIENTO DE LOS CONDUCTORES QUE CONDUCE EL PASO DE LA CORRIENTE POR EL AISLANTE DE LA CAPA DE AISLAMIENTO (10), FLUYE SUFICIENTE CORRIENTE A TRAVES DE LA RESISTENCIA (R3) PARA ELEVAR SU TEMPERATURA SUFICIENTEMENTE PARA ACCIONAR EL FUSIBLE (F1) E INTERRUMPIR EL CIRCUITO QUE CONDUCE A LOS CONDUCTORES (R1, R2).
