Description
Das Hauptpatent gig 829 bezieht sich auf den unterhalb einer stahlblechgekapselten Schaltanlage innerhalb des Erdreichs angeordneten Transformator. Der ölgefüllte Transformatorbehälter ist derart in das Erdreich eingelassen, daß sein Deckel oben bündig mit dem Erdreich abschließt und die glatten Behälterwände aus Gründen der guten Wärmeableitung satt an der Erde anliegen.The main patent gig 829 relates to the transformer located beneath a sheet steel encapsulated switchgear within the ground. The oil-filled transformer container is embedded in the ground in such a way that its cover is flush with the ground at the top and the smooth container walls fit snugly against the ground for reasons of good heat dissipation.
Die Erwärmung des Transformators in Betrieb bleibt unterhalb einer bestimmten Grenze, wenn ein genügend großer Wärmeaustausch zwischen Transfortnatorbehälter und der ihn umgebenden Erde erfolgen kann. Dies ist nur möglich bei genügend großer Oberfläche des Behälters. Sitzt ein Transformator bestimmter Leistung in dem normalerweise für ihn vorgesehenen Behälter innerhalb des Erdreichs, so kann unter Umständen die Wärmeabgabe an das Erdreich zu klein sein. Eine Abhilfe wäre dann insofern möglich, als man den erforderlichen Transformator in einem größeren Behälter unterbringen würde mit entsprechend größerer wärmeabgebender Oberfläche. Dies bedeutet aber einen unwirtschaftlichen Aufwand an Eisenblech für den größer gewählten Behälter wie auch an Öl, Die Erfindung bringt eine Anordnung, die sich erheblich wirtschaftlicher gestaltet. Sie besteht darin, daß die Wände des in das Erdreich zu versenkenden Transformatorkessels derart gestaltet werden, daß dessen gesamte, mit dem Erdreich unmittelbar in Berührung stehende Oberfläche bei relativ geringfügiger Steigerung des Ölbedarfes möglichst groß ist. Vorteilhafterweise bildet man dazu den Kessel als Harfenrohrkasten aus. Die Rohre, die sich auf allen Seiten des Kessels befinden, werden so dimensioniert, daß die Gesamtoberfläche die erforderliche Größe erhält.The heating of the transformer in operation remains below a certain limit if a sufficiently large heat exchange can take place between the transformer container and the earth surrounding it. This is only possible if the surface of the container is large enough. If a transformer of a certain power is located in the container normally provided for it within the ground, the heat dissipation to the ground may be too small. A remedy would then be possible to the extent that the required transformer would be accommodated in a larger container with a correspondingly larger heat-emitting surface. However, this means an uneconomical expenditure on sheet iron for the larger selected container as well as on oil. The invention provides an arrangement which is considerably more economical. It consists in that the walls of the transformer tank to be sunk into the ground are designed in such a way that its entire surface, which is in direct contact with the ground, is as large as possible with a relatively slight increase in the oil requirement. For this purpose, the kettle is advantageously designed as a harp tube box. The pipes, which are located on all sides of the boiler, are dimensioned so that the total surface area is of the required size.
In der Zeichnung ist ein Ausführungsbeispiel der Anordnung gemäß der Erfindung dargestellt. Der Transformator mit dem Harfenrohrkasten i sitzt im Erdreich 2 auf dem z. B. betonierten Sockel 3. Der Deckel 4 des Transformators schließt oben mit dem Erdreich bündig ab und ist als Träger für die oberhalb des Erdreichs angeordnete Schaltanlage 5 ausgebildet. Die Elemente der Schaltanlage stehen mit den Durchführungen 6 des Transformators in Verbindung.The drawing shows an embodiment of the arrangement according to FIG Invention shown. The transformer with the harp tube box i sits in the ground 2 on the z. B. concrete base 3. The cover 4 of the transformer closes at the top flush with the ground and is used as a carrier for the above ground Switchgear 5 formed. The elements of the switchgear stand with the bushings 6 of the transformer in connection.
