Wasserturbinen-AggregatWater turbine unit

Es ist bekannt, Wasserturbinen-Aggregate, die aus Turbine und Generator mit oder ohne Zwischengetriebe bestehen, innerhalb eines von Wasser durchströmten Kanales anzuordnen. Die Maschinen des Aggregates sind als einzelne Einheiten auf Fundamenten in ein Gehäuse eingebaut und stehen nicht mit dem Gehäuse in wärmeleitender Verbindung. Durch diesen Einbau ergeben sich verhältnismäßig große Abmessungen für das Aggregatgehäuse und die für die Wasserführung bestimmten Anlagenteile. Auch wird der Strömungswiderstand durch die Abmessungen des Aggregatgehäuses verhältnismäßig groß, was einen verhältnismäßig geringen Wirkungsgrad der Gesamtanlage zur Folge hat. Durch die besondere Ausbildung der für den Einbau bestimmten einzelnen Maschinen des Aggregates und die erforderlichen Abmessungen der Gesamtanlage stellen sich die Gestehungskosten sehr hoch.It is known, water turbine units, consisting of turbine and generator with or without Intermediate gears exist to be arranged within a channel through which water flows. The machines of the aggregate are in a single unit on foundations Housing installed and are not in heat-conducting connection with the housing. This installation results in relatively large dimensions for the unit housing and the parts of the system intended for the water supply. Also is the flow resistance relatively large by the dimensions of the unit housing, what results in a relatively low degree of efficiency of the overall system. Through the special design of the individual machines of the unit intended for installation and the required dimensions of the overall system are the prime costs very high.

Nach der vorliegenden Erfindung wird der Bau sog. Unterwasserkraftwerke ganz wesentlich dadurch vereinfacht und verbilligt, daß der Ständer der elektrischen Maschine in das zu seiner Führung und Befestigung dienende Aggregatgehäuse eingeschoben wird. Der Ständer und das vom Triebwasser umspülte Aggregatgehäuse stehen somit wärmeleitend miteinander in Verbindung, und die Abgabe"1!According to the present invention, the construction of so-called underwater power plants is considerably simplified and made cheaper in that the stator of the electrical machine is pushed into the unit housing serving for its guidance and fastening. The stator and the unit housing, which is surrounded by the driving water, are thus connected to one another in a thermally conductive manner, and the output " 1 !

der Ständenvärme erfolgt über die Gehäusewand direkt an das vorbeiströmende Wasser. Die Wärmeabfuhr ist bei diesem Einbau der elektrischen Maschine die denkbar günstigste, und die Abmessungen des Gesamtaggregates ■werden gegenüber den bekannten Ausführungsformen wesentlich herabgesetzt.the booth warmth occurs through the housing wall directly to the flowing water. With this installation of the electrical machine, the heat dissipation is the most favorable conceivable, and the dimensions of the overall unit ■ are compared to the known embodiments substantially reduced.

Es ist zwar schon bekannt, den Ständer einer elektrischen Maschine an dem vom Wasser umspülten Gehäuse anliegen zu. lassen. Dabei handelt es sich aber um Kleinaggregate, die z. B. als Pumpe in Verbindung mit dem Förderrohr in einen Brunnen o. dgl. hinabgelassen werden. Die Erfindung findet demgegenüber bei Unterwasserkraftwerken Anwendung, bei denen der Aggregatkörper in den Wehrkörper eines Flusses oder in ein ähnliches Bauwerk als Kraftstation eingebaut wird. Bei solchen Bauwerken hat der Einbau der elektrischen Maschine in das Aggregatgehäuse gemäß der Erfindung im Zusammenhang mit der erwähnten besonders guten Wärmeabfuhr eine wesentliche Vereinfachung und Verbilligung der gesamten Anlage einschließlich des Bauwerkes zur Folge.Although it is already known, the stator of an electrical machine on the from The water-rinsed housing is in contact with it. permit. However, these are small units, the z. B. as a pump in connection with the delivery pipe in a well o. The like. Lowered. The invention finds on the other hand in underwater power plants application, in which the aggregate body in the weir body of a river or in a similar structure is installed as a power station. In such structures, the installation has the electrical machine in the unit housing according to the invention in connection with the mentioned particularly good heat dissipation a significant simplification and cheaper of the entire system including the structure.

Eine weitere Verbesserung der Kühlwirkung kann noch dadurch erzielt werden, daß das Ständerblechpaket der eingebauten elektrischen.

The internal air flow, which is used to cool the Runner is used, and he is by stroking along the unit housing inner wall particularly intensively recooled in a manner known per se. The . Heat is dissipated from the stand via the Ribs directly on the unit housing.

In der Zeichnung" ist ein Ausführungsbeispiel des Erfindungsgedankens dargestellt. Der Generators ist als Einbaugenerator ausgebildet und wird durch Rippen / des Ständergehäuses k gegenüber der Innenwand des Aggregatgehäuses e abgestützt und geführt. Die Zwischenräume zwischen den Rippen/ dienen zur Bildung von Führungskanälen für den Innenkühlluftstroin. Das Einsetzen des Generators α erfolgt durch einfaches Einschieben in das Aggregatgehäuse e. An den Einbaugeneratora kann auch die Erregermaschine b mitangebaut werden. Ein Zahnradgetriebe c dient zur Kupplung des Generators α mit dem Laufradßi der Turbine. Die Gehäuse e und / dienen zum wasserdichten Abschließen des Generators λ und des Getriebes c. Durch die Nabe des Turbinenlaufradesji? wird die äußere Gehäuseform des gesamten Aggregates zur Tropfenform ergänzt. In the drawing "an embodiment of the inventive concept is shown. The generator is designed as a built-in generator and is supported and guided by ribs / of the stator housing k against the inner wall of the unit housing e . The spaces between the ribs / serve to form guide channels for the internal cooling air flow. the insertion of the generator is α simply by pushing in the assembly housing e. at the Einbaugeneratora the exciter can be mitangebaut b. A gear transmission c is used for coupling of the generator α with the Laufradßi of the turbine. the casing e and / are used for water-tight sealing of the Generator λ and the gearbox c. The hub of the turbine impeller complements the outer housing shape of the entire unit to a teardrop shape.
