Abstract

Ölgekühlte Transformatoren werden häufig mit einer Messkammer (1) für auftretenden Wasserstoff überwacht, da der Wasserstoff ein Indikator für in dem Trafoöl gelöste Crackprodukte ist. Der Wasserstoff kann dabei über eine gasdurchlässige Membran von der Transformatorkammer (2) in die Messkammer (1) diffundieren. Bei einer Leckage kann jedoch auch Trafoöl (11) einbrechen, was unter anderem zu Fehlmessungen führen kann. Erfindungsgemäss wird daher der Gassensor (10) der Messkammer (1) derart angeordnet, dass er bei einem Öleinbruch wenigstens teilweise in das Öl eintaucht und dadurch den Öleinbruch detektieren kann. In weiterer Ausgestaltung der Erfindung wird die Messgenauigkeit durch eine Heizeinrichtung (7) im Bereich der Membran (3) verbessert. Auch ist ein Verschlusskörper (82) für austretendes Trafoöl vorsehbar.
