Abstract

EN EL ROTOR DE UNA MAQUINA ELECTRICA, ESPECIALMENTE TURBOGENERADOR, SE CONSIGUE LA UNION DEL ARROLLAMIENTO DEL ROTOR CON LOS ANILLOS DE LAZO O EL EQUIPO DE EXCITACION ROTATIVA POR MEDIO DE CONDUCTORES (4,5) DE CORRIENTE DE EXCITACION, QUE ESTAN DISPUESTOS DE FORMA EMPAREJADA EN UN TALADRO (3) DE EJE CENTRAL DEL ROTOR (1). PARA ELLO LA DISPOSICION DE ANILLO DE LAZO O EL EQUIPO DE EXCITACION ESTA DISPUESTO SOBRE UNA ZONA DEL EJE, QUE CON EL EJE (1) ROTOR ESTA UNIDO CON UN ACOPLAMIENTO (17) DESMONTABLE. EN MAQUINAS REFRIGERADAS POR AGUA ES PROBLEMATICA LA ESTANQUEIDAD DE LA CONDUCCION DE EXCITACION EN LA ZONA DE ACOPLAMIENTO. PARA ELLO SE HAN PREVISTO EN EL TALADRO (3) DE EJE CENTRAL PIEZAS (31,32) DE CONEXION DE FORMA PREFERENTE, EN LAS QUE ESTAN SUJETOS DE FORMA DESMONTABLE LOS BULONES (7,8) DE GUIA DE AFLUENCIA DE CORRIENTE QUE DISCURREN DE FORMA RADIAL. LOS CONDUCTORES DE CORRIENTE DE EXCITACION ESTAN EJECUTADOS EN FORMA DE TUBOS (4,5) METALICOS CON SECCION TRANSVERSAL CIRCULAR REDONDA. ESTOS TUBOS (4,5) ESTAN UNIDOS DE FORMA FIJA EN EL OTRO EXTREMO CON PIEZAS (36,37) DE CONEXION MACIZAS EN EL LADO DE ACOPLAMIENTO. LOS EXTREMOS (36A, 37A) DE ESTA PIEZA DE CONEXION QUE PENETRAN EN UNA PLACA (43) DE UNION EN EL ACOPLAMIENTO ESTAN AISLADOS ELECTRICAMENTE. LA ESTANQUEIDAD DE LA PLACA (43) DE UNION CONTRA EL EJE (1) DEL ROTOR Y CONTRA LA PLACA (43) DE JUNTA SE CONSIGUE CON LOS EXTREMOS (36A, 37A) DE LAS (36,37) DE CONEXION EN EL LADO DE ACOPLAMIENTO POR MEDIO DE ANILLOS DE ESTANQUEIDAD. DE FORMA VENTAJOSA SE ENCUENTRAN PRESENTES SOLAMENTE SUPERFICIES DE ESTANQUEIDAD PLANAS O CIRCULARES REDONDAS.
