Abstract
UN CALENTADOR POR INDUCCION QUE UTILIZA CORRIENTE DE ALTA FRECUENCIA, PARA CALENTAR UN ARTICULO UN ARTICULO SEMEJANTE A UN ANILLO, QUE COMPRENDE UN NUCLEO MAGNETICAMENTE PERMEABLE, HECHO DE UN MATERIAL DE FERRITA, SEMEJANTE A UNA ABRAZADERA Y QUE TIENE UNA PORCION ABISAGRADA MOVIBLE ENTRE LAS POSICIONES DE ABIERTA Y CERRADA, (PERMITIENDO EL MONTAJE DEL ARTICULO ANULAR ALREDEDOR DE UNA PORCION DEL NUCLEO CUANDO ESTE ULTIMO SE ENCUENTRA EN LA POSICION DE ABIERTO); UN DEVANADO QUE RODEA EL NUCLEO PARA EXCITARLO, FORMANDO EL PRIMARIO DE UN CONJUNTO DE TRANSFORMADOR, A LA VEZ QUE ELARTICULO FORMA EL SECUNDARIO DE DICHO CONJUNTO DE TRANSFORMADOR; UNA FUENTE ALIMENTADORA DE ALTA FRECUENCIA, QUE FUNCIONA EN EL MODO CONMUTADO Y QUE ESTA CONECTADA AL PRIMARIO, TENIENDO UNA FRECUENCIA DE TRABAJO SUFICIENTEMENTE ELEVADA (COMO PARA QUE EL NUCLEO Y EN EL ARTICULO SE PRODUZCA UN FLUJO MAGNETICO DE DENSIDAD BAJA, A FIN DE EVITAR LA NECESIDAD DE DESMAGNETIZAR EL ARTICULO LUEGO DE QUE HA SIDO CALEN TADO POR INDUCCION); MEDIOS DE CONTROL DE FRECUENCIA DE LAZO ENGANCHADO EN FASE PARA DETECTAR LA CARGA DE CORRIENTE IMPUESTA POR EL ARTICULO, Y PARA CONTROLAR ASI LA FRECUENCIA DE SUMINISTRO DE ACUERDO CON LA CARGA DETECTADA, (DE MODO QUE EL NUCLEO Y EL ARTICULO ESTAN EN RESONANCIA); Y MEDIOS DETECTORES DE TEMPERATURA Y MEDIOS CONMUTADORES PARA DETECTAR LA TEMPERATURA DEL ARTICULO CALENTADO POR INDUCCION (Y PARA TERMINAR INMEDIATAMENTE EL SUMINISTRO DE CORRIENTE AL ARROLLAMIENTO PRIMARIO CUANDO LA TEMPERATURA DETECTADA ALCANZA UN VALOR PREDETERMINADO).AN INDUCTION HEATER USING HIGH FREQUENCY CURRENT, TO HEAT AN ARTICLE AN ARTICLE SIMILAR TO A RING, WHICH INCLUDES A MAGNETICALLY PERMEABLE NUCLEUM, MADE OF A FERRITE MATERIAL, LIKE A POST-MOUNTED BRACKET OPEN AND CLOSED, (ALLOWING THE ASSEMBLY OF THE ANNULAR ARTICLE AROUND A PORTION OF THE NUCLEUS WHEN THIS LAST IS IN THE OPEN POSITION); A WINDING SURROUNDING THE NUCLEUS TO EXCITING IT, FORMING THE PRIMARY OF A SET OF TRANSFORMER, AT THE SAME TIME THE ARTICLE FORMS THE SECONDARY OF SUCH TRANSFORMER SET; A HIGH FREQUENCY POWER SUPPLY, THAT WORKS IN THE SWITCHED MODE AND THAT IS CONNECTED TO THE PRIMARY, HAVING A SUFFICIENTLY HIGH WORKING FREQUENCY (SO THAT THE CORE AND IN THE ARTICLE PRODUCE A LOW DENSITY MAGNETIC FLOW, TO THE NEED TO DEMAGNETIZE THE ARTICLE AFTER IT HAS BEEN HEATED BY INDUCTION); MEANS OF CONTROLLING THE FREQUENCY OF THE LOOP LINKED IN PHASE TO DETECT THE CURRENT LOAD IMPOSED BY THE ARTICLE, AND TO CONTROL THE FREQUENCY OF SUPPLY ACCORDING TO THE LOAD DETECTED, (SO THAT THE CORE AND THE ARTICLE ARE IN RESONANCE); AND TEMPERATURE MEANS DETECTORS AND SWITCHING MEANS TO DETECT THE TEMPERATURE OF THE ITEM HEATED BY INDUCTION (AND TO TERMINATE IMMEDIATELY THE SUPPLY OF CURRENT TO THE PRIMARY WINDING WHEN THE DETECTED TEMPERATURE REACHES A DEFAULT VALUE).
