Abstract

SISTEMA Y METODO PARA VIGILAR LA HOLGURA ENTRE UNA PLURALIDAD DE SEGMENTOS DE ENVUELTA DE ALABE Y UNA PARTE ESTACIONARIA DE UNA TURBINA, QUE COMPRENDEN UNA PLURALIDAD DE PERCEPTORES PARA EFECTUAR VARIAS MEDICIONES DE LA HOLGURA ENTRE LA PARTE ESTACIONARIA DE LA TURBINA Y LOS SEGMENTOS DE ENVUELTA EN CADA FILA DE ALABES DE TURBINA. LAS MEDICIONES SON PROMEDIADAS POR UN MICROORDENADOR PARA OBTENER UN VALOR MEDIO DE LA HOLGURA PARA CADA SEGMENTO DE ENVUELTA. EL MICROORDENADOR ANALIZA ENTONCES LOS VALORES DE HOLGURA MEDIA PARA CADA SEGMENTO DE ENVUELTA, PARA DETERMINAR SI, Y CUANDO, LA HOLGURA ENTRE UN SEGMENTO DE ENVUELTA Y LA PARTE ESTACIONARIA DE LA TURBINA ESTA PROXIMA A UN VALOR CRITICO. SE GENERA ENTONCES UNA RESPUESTA DE SALIDA AL ANALISIS ANTERIOR PARA SEÑALAR UNA CONDICION CRITICA.
