Description

Einrichtung zum Anfeuchten der den Kommutator oder die Schleifringe umgebenden Luft in geschlossenen elektrischen Maschinen mit Kreislaufkühlung Es ist bereits bekannt, daß der Feuchtigkeitsgehalt der den Kommutator oder die Schleifringe elektrischer Maschinen umgebenden Luft für die richtige Arbeitsweise des Kommutators oder der Schleifringe von wesentlicher Bedeutung ist, da eine zu trockene Luft einen zu raschen Verschleiß der Bürsten des Kommutators oder der Schleifringe infolge Verstaubung verursacht. Man hat daher bei einer solchen bekannten Einrichtung den gesamten Maschinenraum künstlich befeuchtet.Device for moistening the commutator or slip rings surrounding air in closed electrical machines with circuit cooling Es is already known that the moisture content of the commutator or the slip rings Air surrounding electrical machines for the correct operation of the commutator or the slip rings is essential because the air is too dry too rapid wear of the brushes of the commutator or the slip rings as a result Causes dustiness. You therefore have in such a known device entire engine room artificially humidified.

Die Erfindung bezieht sich auf eine besonders zweckmäßige Einrichtung zur Feuchthaltung der den Kommutator oder die Schleifringe umgebenden Luft von elektrischen Maschinen, an denen eine Kreislaufkühlung im Innern der Maschine auch den Kommutator oder die Schleifringe bestreicht, wobei für die Rückkühlung der Kreislaufkühlung Kühlwasser (z. B. in Kühlwasserröhren) verwendet wird. Erfindungsgemäß steht das Kühlwasser mit der Kreislaufkühlung über poröse Trennwände, z. B. poröse Rohrstücke, in Verbindung, .so daß die Luft der Kreislaufkühlung ständig Feuchtigkeit über diese porösen Trennwände aus dem Kühlwasser aufnehmen kann. Die Luft kann daher durch die geschilderten Mittel leicht.auf dem erforderlichen Feuchtigkeitsgehalt, der mindestens 25% beträgt, gehalten werden.The invention relates to a particularly useful device to keep the air surrounding the commutator or slip rings moist from electrical Machines on which circuit cooling inside the machine also includes the commutator or brushed the slip rings, whereby for the recooling the circuit cooling Cooling water (e.g. in cooling water pipes) is used. According to the invention that stands Cooling water with the circuit cooling via porous partitions, e.g. B. porous pipe pieces, in connection, .so that the air of the circuit cooling constantly moisture over this porous partitions can absorb from the cooling water. The air can therefore pass through the described means easily. to the required moisture content, which is at least 25%.

Die neue Einrichtung hat außerdem den Vorteil, daß man die porösen Trennwände an der Rückkühleinrichtung derart anbringen kann, daß man sie leicht beaufsichtigen und evtl. gegen neue Trennwände austauschen kann. Auch die Regelung der die Trennwände bestreichenden Kühlluft ist verhältnismäßig einfach, da man nicht den gesamten Kühlluftstrom über die Trennwände leiten wird, sondern nur einen regelbaren Teil.The new device also has the advantage that the porous Partition walls can be attached to the cooling device so that they can be easily supervise and possibly replace with new partitions. Also the regulation the coating of the partitions cooling air is relatively easy, since you do not will guide the entire flow of cooling air over the partition walls, but only one controllable Part.

Für die Ausführung der Erfindung kann man an der Rückkühleinrichtung die Röhren, durch deren Inneres das Kühlwasser strömt, teilweise porös ausbilden, so daß die die Kühlwasserröhren außen umstreichende Kühlluft sich genügend mit Feuchtigkeit anreichert. Beispielsweise kann man einzelne Teile der Kühlwasserröhren aus einem porösen Metall herstellen, z. B. aus einem Sintermetall. Man könnte aber auch diese Teile aus einer porösen Keramikmasse herstellen.To carry out the invention, one can use the recooling device the tubes, through the inside of which the cooling water flows, are partially porous, so that the cooling air sweeping around the outside of the cooling water pipes is sufficiently saturated with moisture enriches. For example, you can separate parts of the cooling water pipes from one make porous metal, e.g. B. from a sintered metal. But you could also do this Manufacture parts from a porous ceramic mass.

Wie die Versuche gezeigt haben, läßt sich durch die Einrichtung nach der Erfindung ebenfalls eine wesentliche Verbesserung der Kommutierung undAs the experiments have shown, can be reduced by the device the invention also a significant improvement in commutation and
