Abstract

Es wird ein elektrischer Transformator (10) mit zwei Wicklungen (15, 16), einem Wählschalter (12) und einem Lastschalter (13) beschrieben, wobei der Lastschalter (13) mindestens einen Überschaltwiderstand (22) aufweist. Die Wicklungen (15, 16) und der Überschaltwiderstand (22) sind in einem gemeinsamen Transformatorgehäuse (11) untergebracht, das mit einem Transformatoröl (25) gefüllt ist. Es sind Einrichtungen oder Vorrichtungen vorgesehen, die ein Auftreten eines nicht-zulässigen Betriebszustands, bei dem die Temperatur des Überschaltwiderstands (22) einen vorgegebenen Schwellwert erreicht oder überschreitet, verhindern.
