Abstract

SE DESCRIBE UN INTERRUPTOR ELECTRICO TERMOSENSIBLE PARA USARSE EN APLICACIONES ELECTRICAS DOMESTICAS, TALES COMO DESCONECTAR EL SUMINISTRO ELECTRICO DE UNA APLICACION EN UNA SITUACION DE TEMPERATURA ELEVADA. DICHO INTERRUPTOR ESTA PENSADO PARA QUE FUNCIONE COMO INTERRUPTOR AUTOMATICO, COMO INTERRUPTOR MANUAL O COMO UN INTERRUPTOR PTCR SIN CAMBIOS SIGNIFICATIVOS EN SU FABRICACION. EL CUERPO DEL INTERRUPTOR (20) ESTA MOLDEADO EL PLASTICO E INCORPORA LOS TERMINALES PRIMARIO Y SECUNDARIO (1,2), UNO DE LOS CUALES PROPORCIONA UN MONTAJE DE SOPORTE PARA UN ELEMENTO INTERRUPTOR (4) QUE SE MUEVE PARA EFECTUAR LAS OPERACIONES DE INTERRUPCION ENTRE SU EXTREMO LIBRE Y LA OTRA PARTE DEL TERMINAL. UN ELEMENTO INTERRUPTOR BIMETALICO (7) SE MONTA SOBRE EL ELEMENTO INTERRUPTOR (4), DE MODO QUE SUS MOVIMIENTOS DE RESPUESTA TERMICA PRODUCEN EL MOVIMIENTO DE INTERRUPCION. EL CUERPO DEL INTERRUPTOR (20) SE CONFIGURA PARA SER CAPAZ DE ALOJAR UN ELEMENTO PTCR (11) , QUE ESTA RETENIDO POR UN CONDUCTOR (12) DE TALFORMA QUE EL ELEMENTO PTCR (11) SE MONTA EN EL CAMINO DE LA CORRIENTE A TRAVES DEL INTERRUPTOR CUANDO LOS CONTACTOS ESTA ABIERTOS. EL CALOR QUE SE DESARROLLA EN EL ELEMENTO PTCR (11) LE HACE MANTENER SUSTANCIALMENTE LA CONDICION DE INTERRUPTOR DE PASO, REDUCIENDO LA CORRIENTE DE TRANSITO DEL INTERRUPTOR DE CARGA. OMITIENDO EL ELEMENTO PTCR, SE OBTIENE UN INTERRUPTOR DE DESCONEXION AUTOMATICA, Y SELECCIONANDO LAS CARACTERISTICAS DEL ELEMENTO BIMETALICO Y/O DISPONIENDO EL ELEMENTO INTERRUPTOR PARA QUE SEA BIESTABLE, SE PUEDE OBTENER UNA VERSION DE DESCONEXION MANUAL DEL INTERRUPTOR.
