Abstract

Es wird eine Anordnung (10) mit einem elektrischen Transformator (11) beschrieben, der mit Öl befüllt ist. Es ist ein Öl-Luft-Wärmetauscher (13) vorhanden, der mit dem Transformator (11) über eine Ölleitung (15c) verbunden ist, und dem eine Lüftereinheit (14) zugeordnet ist, mit der Wärme aus dem Öl an Luft abgegeben werden kann. Es ist ein Öl-Wasser-Wärmetauscher (12) vorhanden, der mit dem Transformator (11) und dem Öl-Luft-Wärmetauscher (13) über Ölleitungen (15a, 15b) verbunden ist, und mit dem Wärme aus dem Öl an Wasser abgegeben werden kann, wobei das Wasser mindestens einer Versorgungseinheit zuführbar ist. Es ist eine Temperatur (T) des Öls des Transformators (11) ermittelbar. Die Lüftereinheit (14), insbesondere die Drehzahl eines Ventilators der Lüftereinheit (14), ist in Abhängigkeit von der Temperatur (T) beeinflussbar.

An arrangement (10) with an electrical transformer (11) filled with oil is described. There is an oil-air heat exchanger (13) connected to the transformer (11) via an oil line (15c) and associated with a fan unit (14) for releasing heat from the oil to air , There is an oil-water heat exchanger (12), which is connected to the transformer (11) and the oil-air heat exchanger (13) via oil lines (15a, 15b), and delivered with the heat from the oil to water can be, wherein the water is supplied to at least one supply unit. It is a temperature (T) of the oil of the transformer (11) can be determined. The fan unit (14), in particular the speed of a fan of the fan unit (14), can be influenced as a function of the temperature (T).
