Abstract

UN CALENTADOR ELECTRICO RADIANTE (10) PROVISTO DE 2 ELEMENTOS CALEFACTORES DE ALAMBRE DE RESISTENCIA BOBINADOS (22, 24) CADA UNO CONECTADO A UN TERMINAL (N) DE UN SUMINISTRO DE POTENCIA A TRAVES DE LOS RESPECTIVOS RECTIFICADORES. ESTOS RECTIFICADORES ESTAN CADA UNO HECHOS DE DOS BRAZOS PARECIDOS A POSTES DE UN RECTIFICADOR DE PUENTE (34) CONECTADOS EN PARALELO, Y DISPUESTOS PARA QUE PASE LA CORRIENTE A TRAVES DE UN ELEMENTO CALEFACTOR (22) EN MEDIO CICLOS POSITIVOS DE FORMA DE ONDA DEL SUMINISTRO DE POTENCIA, Y A TRAVES DE OTRO ELEMENTO CALEFACTOR (24) EN MEDIO CICLOS NEGATIVOS. LOS ELEMENTOS ESTAN TASADOS PARA DISIPACION DE POTENCIA CONTINUA BAJO ESTAS CIRCUSTANCIAS. UN TERMISTOR PTC (36) ESTA CONECTADO ENTRE LOS EXTREMOS DE LOS ELEMENTOS CALEFACTORES CONECTADOS A LOS RECTIFICADORES. OPCIONALMENTE UN TERMISTOR PTC (40) PODRA CONECTARSE EN SERIE CON EL TERMISTOR PTC. DESPUES DEL ACCIONAMIENTO INICIAL EL TERMISTOR PTC ESTA A PUNTO DE CONVERTIRSE EN UN CORTOCIRCUITO, DE FORMA QUE LA CORRIENTEFLUYE A TRAVES DE AMBOS ELEMENTOS CALEFACTORES EN LOS DOS MEDIOS CICLOS DE POLARIDAD, DISIPANDO DOBLEMENTE SU POTENCIA TASADA. LOS ELEMENTOS AUMENTAN LA TEMPERATURA MAS RAPIDAMENTE QUE SE HUBIERAN SIDO ACTIVADOS INICIALMENTE A SOLAMENTE SU POTENCIA EVALUADA, DE FORMA QUE LA RESPUESTA VISIBLE DE LOS ELEMENTOS A LA ACTIVACION SEA MAS RAPIDA. MIENTRAS TANTO, EL TERMISTOR PTC AUMENTA LA RESISTENCIA DEBIDO AL CALENTAMIENTO PROPIO, RETIRANDO EL CORTOCIRCUITO DESPUES DE UNOS POCOS SEGUNDOS, REDUCIENDO LA DISIPACION DE LA POTENCIA EN LOS ELEMENTOS A SU NIVEL NORMAL Y PROTEGIENDOLOS DE LAS TEMPERATURAS DE OPERACION EXCESIVAS.
