Abstract

APARATO PARA DETERMINAR LA DIFERENCIA RELATIVA DE DESPLAZAMIENTO ANGULAR INSTANTANEO ENTRE DOS MASAS GIRATORIAS DE UN SISTEMA MECANICO. SOBRE UN EJE (SH) HAY DISPUESTAS CUATRO MASAS GIRATORIAS (I1, I2, I3, I4) QUE REPRESENTAN LAS INERCIAS DE LOS ROTORES DEL EXCITADOR, DEL GENERADOR, DE LA TURBINA DE BAJA Y DE LA TURBINA DE ALTA, RESPECTIVAMENTE. EL VAPOR DE AGUA (ST) HACE GIRAR LAS SECCIONES DE LA TURBINA Y LOS ROTORES DEL EXCITADOR Y DEL GENERADOR, PROPORCIONANO ENERGIA ELECTRICA (L1, L2, L3, L4). MEDIANTE UNA ANALOGIA ELECTRICA QUE SE EXCITA CON EL PAR APLICADO AL EJE DEL GENERADOR, SE DETECTAN LOS DESPLAZAMIENTOS INSTANTANEOS DE CADA MASA RESPECTO A UNA REFERENCIA FIJA. SE APLICA PARA ESTIMAR LA DEFORMACION DEL EJE DE UN SISTEMA DE TURBOGENERADOR.
