Abstract

LA INVENCION SE REFIERE A UN ANILLO DEFLECTOR CON ESPACIO DE AIRE FACILMENTE REMOVIBLE PARA UNA MAQUINA DINAMOELECTRICA ENFRIADA CON GAS, TAL COMO UN GENERADOR DE TURBINA. EL ANILLO DEFLECTOR COMPRENDE DOS ANILLOS COMPUESTOS CON UN MATERIAL DE SELLADO DEL TIPO DE SANDWICH ENTRE ELLOS Y ENLAZADOS DENTRO DE UNA ESTRUCTURA INDIVIDUAL. EL ANILLO DE SELLADO SE CONECTA A LAS EXTENSIONES DE PLACA EN FORMA DE DEDO QUE SON PARTE INTEGRAL DEL NUCLEO DEL GENERADOR, Y FORMAN UN ESPACIO DE AIRE DE SELLADO ENTRE EL ANILLO DE RETENCION DEL ROTOR Y LA CUÑA DEL EXTREMO QUE SE EXTIENDE A PARTIR DE LAS RANURAS DE LA BOBINA DEL ESTATOR. EL CONJUNTO DEFLECTOR CON ESPACIO DE AIRE DE LA PRESENTE INVENCION EFECTUA UN PROCESO DE SELLADO EFECTIVO DE LA ZONA DE ALTA PRESION DEL EXTREMO DE LA EXCITACION DEL GENERADOR, CON RESPECTO A LA ZONA DEL ESPACIO DE AIRE RADIAL DE PRESION INFERIOR LOCALIZADA ENTRE EL ROTOR DEL GENERADOR Y EL ESTATOR, CON LO QUE EL GAS DE REFRIGERACION SE VE FORZADO A FLUIR DENTRO DEL ROTOR Y DELESTATOR.
