Description

  

      Hühlanoranung    an Transformatoren.    Es ist bekannt, einen mit Radiatoren     ver-          sehenen    Transformator durch Lüfter anzu  blasen, die unterhalb dieser Radiatoren an  geordnet sind und über diese einen Luftstrom  von unten nach oben schicken. Auch ist  bereits zur wirksameren Kühlung vorgeschla  gen worden, dass der von den Lüftern aus  gestossene Luftstrom an den Radiatoren von  aussen schräg     vorbeistreicht.    Die Lüfter er  weisen sich für den Transport hierbei jedoch  sehr sperrig, da sie seitlich hervorstehen und  u. U. über das Lademass des Transformators  hinausragen.  



  Erfindungsgemäss wird nun der Vorschlag  gemacht, die Radiatoren paarweise schräg  zueinander anzuordnen, derart, dass ihre obern  Enden einander genähert sind und die untern  Enden voneinander entfernt liegen. Es wird  dadurch erreicht, dass der Eintrittswiderstand  der Luft in die Radiatoren bedeutend herab  gesetzt wird und damit zugleich die erfor  derliche Leistung der     Lüftermotoren.    Ferner  wird eine bessere Luftverteilung zwischen  den Radiatoren erzielt.    Die Erfindung sei an Hand eines Aus  führungsbeispiels erläutert. 1 stellt in der  Zeichnung den Transformator dar, der mit  Radiatoren 2 versehen ist. Diese sind erfin  dungsgemäss paarweise an ihren obern Enden  einander zugekehrt. Jedem     Radiatorpaar    ist  ein Lüfter 3 zugeordnet, der unterhalb und  zwischen diesen befestigt ist.



      Shell fittings on transformers. It is known to blow a transformer provided with radiators through fans, which are arranged below these radiators and send an air flow from below to above. For more effective cooling, it has also already been proposed that the air flow emitted by the fans sweep obliquely past the radiators from the outside. The fans, however, are very bulky for transport because they protrude laterally and u. U. protrude beyond the load dimension of the transformer.



  According to the invention, the proposal is now made to arrange the radiators in pairs at an angle to one another, in such a way that their upper ends approach one another and the lower ends are remote from one another. It is achieved in that the entry resistance of the air into the radiators is significantly reduced and thus at the same time the required power of the fan motors. Furthermore, better air distribution between the radiators is achieved. The invention is explained using an exemplary embodiment from. 1 shows the transformer provided with radiators 2 in the drawing. According to the invention, these are facing each other in pairs at their upper ends. Each pair of radiators is assigned a fan 3, which is attached below and between them.
