Description

Wasserumlaufkühlung für ölgefüllte.-Apparate, z: B. Öltransformatoren, mit Standrohr für den Frischwasserüberlauf 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 Frischwasserüberlaufrohr 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 evtl. Wasser in das öl gedrückt wird. In dieses Standrohr darf kein Durchflußhindernis (Abschlußhahn) eingebaut werden, so daß jederzeit ein vollständig freier Auslauf des Wassers gewährleistet ist. Da das Wasser im Standrohr nur unter statischem Druck steht, also eine stillstehende Wassersäule bildet, so besteht die Gefahr, daß das Wasser bei niedriger Temperatur einfrieren und dadurch die Kühlanlage beschädigen kann.Water circulation cooling for oil-filled devices, e.g. oil transformers with standpipe for the fresh water overflow When cooling oil-filled apparatus with water, z. B. of transformers, with external or internal oil circulation, it is known a Use standpipe for fresh water overflow. The fresh water overflow pipe has the purpose of silting up the cooling water channels inside the oil tank to prevent that a water overpressure occurs compared to the oil pressure and thereby there is a risk that water may be pressed into the oil. In this standpipe no flow obstacle (shut-off valve) must be installed, so that a completely free drainage of the water is guaranteed. Because the water in the standpipe is only under static pressure, i.e. forms a static column of water, like this there is a risk that the water will freeze at low temperature and thereby can damage the cooling system.

Dieser Nachteil wird erfindungsgemäß dadurch vermieden, daß das Standrohr für den Frischwasserüberlauf in das Kühlwasserabflußrohr eingebaut ist. In der Zeichnung ist ein Ausführungsbeispiel der Erfindung schematisch dargestellt. G ist ein Kühlkörper, dem das öl aus dem Transformatorbehälter bei A zufließt, während das gekühlte öl bei B wieder zum Transformator zurückfließt. Das Kühlwasser wird dem Rohrsystem des Kühlkörpers G durch die Leitung C zugeführt, das erwärmte Kühlwasser fließt durch das Rohr D ab. E ist das Standrohr für den Frischwasserüberlauf, das mit einer Rückstrahlkappe F versehen ist. Das Standrohr E ist innerhalb des Kühlwasserabflußrohres D eingebaut, so daß die Gefahr des Einfrierens des ständig von dem erwärmten, abfließenden Kühlwasser umgebenen Standrohrs völlig abgeschlossen ist.This disadvantage is avoided according to the invention in that the standpipe is built into the cooling water drain pipe for the fresh water overflow. In the drawing an embodiment of the invention is shown schematically. G is a heat sink, to which the oil flows from the transformer tank at A, while the cooled oil flows back to the transformer at B. The cooling water is the pipe system of the heat sink G is fed through the line C, the heated cooling water flows through the pipe D. E is the standpipe for the fresh water overflow that comes with a Reflector cap F is provided. The standpipe E is inside the cooling water drain pipe D incorporated, so that the risk of freezing of the constantly heated, draining Cooling water surrounded standpipe is completely closed.
