 EMI1.1 
 



   Bei der Wasserkühlung ölgefüllter Apparate, z. B. von Transformatoren mit äusserem oder innerem   Ölumlauf   ist es bekannt, ein Standrohr für den Frischwasserüberlauf zu verwenden. Das Frischwasser- überlaufrohr hat den Zweck, bei Verschlammung der Kühlwasserkanäle innerhalb des Ölbehälters zu verhüten, dass ein Wasserüberdruck gegenüber dem Öldruck auftritt und dadurch die Gefahr entsteht, dass eventuell Wasser in das Öl gedrückt wird. In dieses Standrohr darf kein Darchflusshindernis (Abschlusshahn) eingebaut werden, so dass jederzeit ein vollständig freier Auslauf des Wassers gewährleistet   is1.   



  Da das Wasserim Standrohr nur unterstatischem Druck steht, also, so lange die im Ölgefäss untergehrachten Kühlrohre nicht verschlammt sind, eine stillstehende Wassersäule bildet, so besteht die Gefahr, dass das Wasser bei niedriger Temperatur einfrieren und dadurch die Kühlanlage beschädigen kann. 



   Dieser Nachteil wird erfindungsgemäss dadurch vermieden, dass das Standrohr für den Frischwasserüberlauf in das   Kühlwasserabflussrohr   eingebaut ist.

 wieder zum Transformator   zurückfliesst.   Das Kühlwasser wird dem Rohrsystem des Kühlkörpers G durch die Leitung   0   zugeführt, das erwärmte Kühlwasser fliesst durch das Rohr D ab. Eist das Standrohr für den   Frischwasserüberlauf,   das mit einer   Rüekstrahlkappe   F versehen ist. Das Standrohr R ist innerhalb des   Kühlwasserabflussrohres   D eingebaut, so dass die Gefahr des Einfrierens des ständig von dem erwärmten, abfliessenden Kühlwasser umgebenen Standrohrs völlig ausgeschlossen ist.

 EMI1.1
 



   When cooling oil-filled apparatus with water, e.g. B. of transformers with external or internal oil circulation, it is known to use a standpipe for the fresh water overflow. The purpose of the fresh water overflow pipe is to prevent the cooling water ducts inside the oil container from becoming excessively pressurized compared to the oil pressure, which could result in the risk of water being pressed into the oil. No flow obstacle (stopcock) may be built into this standpipe, so that a completely free drainage of the water is guaranteed at all times.



  Since the water in the standpipe is only under static pressure, i.e. as long as the cooling pipes in the oil tank are not silted up, forming a static water column, there is a risk that the water will freeze at low temperatures and thereby damage the cooling system.



   This disadvantage is avoided according to the invention in that the standpipe for the fresh water overflow is built into the cooling water drainage pipe.
 EMI1.2
 flows back to the transformer. The cooling water is fed to the pipe system of the heat sink G through line 0, the heated cooling water flows out through pipe D. Is the standpipe for the fresh water overflow, which is provided with a jet cap F. The standpipe R is installed inside the cooling water discharge pipe D, so that the risk of the standpipe constantly surrounded by the heated, draining cooling water freezing is completely excluded.
