In den Figuren bedeuten 1 die Lüfternabe und 2,2' die einzelnen, von dieser getragenen Flügel bzw. Schaufeln;In the figures, 1 denotes the fan hub and 2, 2 'denotes the individual blades or blades carried by the latter;
Durch diese Durchtritte kann ein Kühlmittel, vorzugsweise auf die Dioden aufgespritztes Kühlöl, besser die Wärme und eventuell Schmutzpartikel von den rotierenden Gleichrichtern abführen.A coolant, preferably cooling oil sprayed onto the diodes, can better pass through these passages Dissipate heat and possibly dirt particles from the rotating rectifiers.
In der DE-OS 28 19 824 ist eine Kühlanordnung beschrieben, bei der die Gleichrichter an einem Innenabschnitt eines mit ihnen rotierenden Gehäuses angebracht sind. Zur besseren Kühlung weist das Gehäuse Eintritts- und Austrittsöffnungen für ein Kühlmittel, wie öl oder Luft, auf.In DE-OS 28 19 824 a cooling arrangement is described in which the rectifier on an inner section a housing rotating with them are attached. For better cooling, the housing has Inlet and outlet openings for a coolant, such as oil or air.
Die beiden zuvor beschriebenen Anordnungen sind nicht variabel und ohne größeren Aufwand einsetzbar, sofern Luft als Kühlmittel statt Öl benutzt wird und die laufenden Querschnitten.The two arrangements described above are not variable and can be used without great effort, if air is used as a coolant instead of oil and the running cross-sections.
In Fig.3 ist eine Anordnung im Zusammenbau mit einer aus Haupt- und Hilfserregermaschine 6 und 5 bestehenden Erregungseinheit für eine elektrische Synchronmaschine mit einem Axiallüfter dargestellt.In Fig.3 there is an arrangement in the assembly with an excitation unit consisting of a main and auxiliary exciter 6 and 5 for an electrical synchronous machine shown with an axial fan.
Hierbei sind noch die Läuferwicklung mit 7 bzw. 8 und die Ständerwicklungen von Haupt- und Hilfserregermaschine mit 9 bzw. 10 bezeichnet. Führungshauben 11 und 12 leiten die Kühlluft im wesentlichen zu den sich im Betrieb sonst zu stark erwärmenden, genannten Wicklungen und deren jeweiligem Eisenkörper. Am günstigsten ist es natürlich, wenn, wie dargestellt, der Lüfter an dem Punkt mit den durchschnittlich niedrig-Here are the rotor windings with 7 or 8 and the stator windings of the main and auxiliary exciter denoted by 9 and 10, respectively. Guide hoods 11 and 12 guide the cooling air essentially to themselves During operation, the named windings and their respective iron bodies would otherwise heat up too much. At the It is of course cheapest if, as shown, the fan is at the point with the average low-
sten Temperaturen des Kühlluftkreislaufes d.h. im Kühlluftzufuhrbereich der Maschine angeordnet ist, da er dann selbst und damit auch die Halbleitergleichrichterelemente am stärksten gekühlt wird.the most temperatures of the cooling air circuit, i.e. in the cooling air supply area of the machine, because it itself and thus also the semiconductor rectifier elements are most strongly cooled.
Die Kühlung der letzteren erfolgt also hier fast ausschließlich durch Wärmeleitung.The cooling of the latter takes place here almost exclusively through thermal conduction.
Die Kühloberfläche des Radiallüfters kann man dadurch günstig gestalten, da3 man die Tragscheibe 24 für die Lüfterschaufeln 2' desselben radial nach innen in bezug auf die Nabe etwas vorstehen läßt, am besten wie dargestellt, gleich weit wie radial nach außen.The cooling surface of the radial fan can be designed in a favorable manner by using the support disk 24 for the fan blades 2 'of the same project radially inwardly with respect to the hub, preferably as shown, as far as radially outwards.
In den Figuren ist mit 20 noch die Anschlußleitung ζ. B. vom Pluspol der Gleichrichterelemente zur Erregerwicklung der Synchronmaschine bei der gewählten Sternschaltung der Gleichrichterelemente, bei der die Lüfternabe als Plus-Sammelring dient mit 21 der jeweilige Anschlußbolzen und mit 22 die jeweilige Anschlußlasche von den Wicklungssträngen der Haupterregermaschine 6 zu den Gleichrichterelementen bezeichnet.In the figures, the connecting line ζ is still at 20. B. from the positive pole of the rectifier elements to the field winding of the synchronous machine with the selected star connection of the rectifier elements, in which the Fan hub as a plus collecting ring serves with 21 the respective connection bolt and with 22 the respective connection lug of the winding strands of the main exciter 6 referred to the rectifier elements.
In F i g. 3 ist noch strichpunktiert die Welle der Synchronmaschine angedeutet an der der Tragring 15 für die Erregermaschinen und den Lüfter gehalten ist.In Fig. 3 the shaft of the synchronous machine is still dash-dotted indicated on which the support ring 15 is held for the excitation machines and the fan.
