Description

Uni bei Groijtransiorniatoren od. dgl. eine ausreichende Kühlwirkung zu erzielen, wird das Kühlmittel mittels eines elektrischen Pumpenaggregatestimgewälzt. DiesePumpen- aggregate werden meist außerhalb des Trans- formatorkessels angeordnet, wodurch iedoch die äußeren Abmessungen des Transformators erheblich vergröllert «-erden. Eine derartige Vergrößerung ist inbesondere bei Wander- transformatoren und Fahrzeugtransformato- ren. bei denen ein bestimmtes Profil flicht über- schritten werden darf. sehr unerwünscht. weil unter Umständen dadurch die Transformator- einheit kleiner gebaut werden mit!'). Mali Ritt deshalb auch schon die Pumpen allein im Transformatorkessel untergebracht und nur den Antriebsmotor außerhalb des Transforma- tors befestigt. Man bat auch schon vorge- schlagen, das gesamte Putnpetiaggregat un- mittelbar im Isü hlinitteistroin des Trans- formators anzuordnen und den Motor auszubilden, d21:1 er entweder imi?1 des Trans- formators läuft oder eilte eigene (:)lftilltitig aufweist und gegen das Öl des Transiorinators abgeschlossen ist. Iin ersten Fall kiinnen leicht Verunreinigungen des Tran:iormatorrileS durch den Motor eintreten, im zweiten Fall wird für die Ölfüllung des Motors ein be- sonderes Ölausdelinutigsgefäll und damit zu- sätzlicher Raum erforderlich. Die Erfindung beseitigt diese Schwierig- keiten.

Die Pumpenkammer besteht aus einem, das Aggre- gat eng umschließenden Rohrstück 4 und aus einem unteren und oberen Deckel ; bzw. 6. die zugleich die Anschlüsse für die Ölleitung bilden. Während der Motor am oberen Lager 7 gegen den Ölraum der Pumpenkammer abge- kapselt ist, bilden die Lagerdeckel b und 9 des unteren Lager: io mit der \lotorwelle i i bz«-. der Nabe 1a des Pumpenrades Spalte 13 und 14, durch die sieh die 0lfüllungdes -Motors bei steigender Teniperatzir nach der Pumpen- kamilier zu ausdehnen kann.

Die Erfindung bietet den Vorteil. claß der durch den Einbau des I'tinilieii<iggregates in den Traitsiorniatorhessel oder in die Ölleitung erzielbare Raumgewinn in -vollkommener Weise ausgenutzt wird, da zusätzliche Ölaus- clehnungsgefäße iür (las Motoriil wegfallen k@nneii.

This pump units are mostly used outside the arranged formatorkessel, whereby iedoch the external dimensions of the transformer considerably increased «-erden. Such a one Magnification is particularly important for hiking transformers and vehicle transformers where a certain profile is mandatory may be stepped. very undesirable. because possibly the transformer unit can be built smaller with!

The invention eliminates this difficulty opportunities.
