Abstract

The oil expansion bellows is intended for oil content transformers etc. and is enclosed in an oil-filled guide pot (4). It can be dewatered outside through a pipe or channels (5) in the bottom plate (6). This design safeguards removal of leakage oil, and possibly condensate outwards. In this manner it is possible to observe leakage from outside, even during transportation. The expansion bellows may be of metal or plastics. It is position can be indicated by a Bowden cable (7).

Description

Öl-Ausdehnungsgefãß ohne innere Ölfüllung Oil expansion vessel without internal oil filling

Das sogenannte 1l negative " Öl-Ausdehnungsgefäß ( 1, Fig. 1 ), bei dem sich im Gefäß - Inneren ( 2 ) kein 01 befindet, hat den Nachteil, das etwaiges Lecköl (und etwaiges Kondenswasser) nicht nach außen abfließt, so daß Undichtigkeiten nicht erkannt werden.The so-called 1l negative "oil expansion tank (1, Fig. 1), at which is no 01 in the inside of the vessel (2) has the disadvantage that any Leak oil (and any condensation water) does not flow to the outside, so that leaks cannot be recognized.

Das " positive " Ausdehnungsgefäß (Fig. 2 ) hat diese Nachteile zwar nicht, es ist aber bein Transport durch Massenkräfte des inneren Öles ( 2 ) mehr gefährdet.The "positive" expansion vessel (Fig. 2) has these disadvantages not, but it is more when transported by the inertia forces of the inner oil (2) endangered.

Es wird nun vorgeschlagen, das Ausdehnungsgefäß ( 1, Fig. 3 ) in einen ölgefüllten Fuhrungstopf ( 4 ) einzuschließen und nach unten mittels Kanülen ( 5 ) in einer Bodenplatte ( 6 ) ( oder z.B. mittels eines Rohres ) zu entwässern, so daß Undichtigkeiten außen bemerkbar werden. Die Nachteile der Ausführungen nach Fig. 1 und 2 sind so vermieden. Die Stellung des Gefäßes kann z. B. mittels eines Bowdenzuges ( 7 ) angezeigt werden.It is now proposed that the expansion vessel (1, Fig. 3) in one Enclose the oil-filled guide pot (4) and move it downwards using cannulas (5 ) to drain in a base plate (6) (or e.g. by means of a pipe), see above that leaks are noticeable outside. The disadvantages of the designs after Fig. 1 and 2 are thus avoided. The position of the vessel can, for. B. by means of a Bowden cable (7) are displayed.

Das Ausdehnungsgefäß kann aus Metall oder aus Kunststoff bestehen.The expansion tank can be made of metal or plastic.
