Abstract
Die Erfindung betrifft Turbogeneratoren mit Gaskuehlung des Staenders und bezieht sich auf die Kuehlung des aktiven Stahls des Staenders. Das Problem wird so geloest, dass die radialen Spalte ueber die Laenge der Maschine in zwei Eintrittszonen und eine Austrittszone gruppiert sind. Die Mitte der Austrittszone stimmt mit der Mitte der Gesamtlaenge des aktiven Stahls ueberein. Der Mittenabstand der linken Eintrittszone von der linken Kante des aktiven Stahls und der Mittenabstand der rechten Eintrittszone von der rechten Kante des aktiven Stahls schwankt zwischen 5 und 25% der Gesamtlaenge des aktiven Stahls.The invention relates to turbogenerators with gas cooling of the stator and relates to the cooling of the active steel of the stator. The problem is solved by grouping the radial gaps over the length of the machine into two entry zones and one exit zone. The center of the exit zone coincides with the center of the total length of the active steel. The center distance of the left entry zone from the left edge of the active steel and the center distance of the right entry zone from the right edge of the active steel varies between 5 and 25% of the total length of the active steel.
