Description

Bei Regeltransformatoren werden im allgemeinen am unteren Ende. einer Transformatordurchführurng im Transformatorenkessel der Stufenwähler und am oberen Ende der Durchführung in Luft der mit der Leitung verbundene Lastschalter angebracht. Diese bekannte Anordnung nimmt aber bei profilgängigen Transformatoren gewöhnlich einen zu großen Raum ein. Es ist daher bereits die gesamte Stufenschalteinrichtung in die Durchführung der zu regelnden Phase eingebaut worden. Hierbei muß dann aber die Durchführung erhebliche Ausmaße erhalten, was sehr kostspielig ist.Regulating transformers are generally at the lower end. one Transformer bushing in the transformer tank of the tap selector and on the top At the end of the bushing in the air, the load switch connected to the line is attached. However, this known arrangement is usually used in profile transformers too large a room. It is therefore already the entire tap changer has been built into the implementation of the phase to be regulated. But then you have to the implementation can get considerable proportions, which is very costly.

Die Erfindung vermeidet diese Nachteile, indem erfindungsgemäß der Lastschalter in einem gegenüber dem Transformatorenöl abgeschlossenen Gehäuse unterhalb der Durchführung angeordnet ist. Für den Fall, daß der mit dem Lastschalter zusammenarbeitende Wähler bereits ein besonderes Gehäuse besitzt, wird der Lastschalter vorteilhaft innerhalb eines gegen dieses Gehäuse abgetrennten Ölraumes untergebracht. Um das Schalteröl wegen der beim Schaltvorgang entstehenden Gasblasen mit der Außenluft in Verbindung zu bringen, ist ferner von dem unterhalb des Transformato-rendeckels befindlichen Schaltergehäuse aus eine Rohrleitung durch die Durchführung nach einem besonderen Ausdehnungsgefäß geführt, welches sich im oberen Teil der Durchführung oder auch auf derselben befindet.The invention avoids these disadvantages by according to the invention Load switch in a closed housing below the transformer oil the implementation is arranged. In the event that the one working with the load switch If the voter already has a special housing, the load switch is advantageous housed within an oil space separated from this housing. To that Switch oil because of the gas bubbles that are formed with the outside air during the switching process to bring in connection, is also from the one below the transformer cover located switch housing from a pipeline through the implementation after a special expansion vessel, which is located in the upper part of the implementation or on the same.

Ein Ausführungsbeispiel dieser Art gibt die Zeichnung wieder. Hier ist mit i der Transformatorkessel mit dem eigentlichen Transformator 2 bezeichnet. 3 stellt die Hochspannungsdurchführung dar, unterhalb der sich an einer isolierenden Aufhängevorrichtung 4 der Lastschalter 5 mit Gehäuse 6 sowie der Stufenwähler 7 befindet. Das Lastschaltergehäuse 6 ist hierbei über die Rohrleitung 8 mit dem Ausdehnungsgefäß 9. verbunden, das im vorliegenden Fall auf der Durchführung 3 angebracht ist. Diese wird gleichzeitig mittels der Klemme io zum Anschluß des Netzes an den Lastschalter verwendet.The drawing shows an embodiment of this type. here i denotes the transformer tank with the actual transformer 2. 3 shows the high-voltage bushing, below which there is an insulating Suspension device 4 of the load switch 5 with housing 6 and the step selector 7 is located. The load switch housing 6 is here via the pipeline 8 with the expansion tank 9. connected, which is attached to the implementation 3 in the present case. These is used at the same time to connect the mains to the load switch by means of terminal io used.
