Description

Sicherheitsvorrichtung zur Verhütung von Schäden bei Rohrbruch in Wasserkraftanlagen Die Erfindung betrifft eine Sicherheitsvorrichtung zur Verhütung von Schäden bei Rohrbruch in Wasserkraftanlagen, insbesondere solchen, die mit einer Wasserturbine, einer Druckrohrleitung zu dieser, einem "Wasserspeicher und einem durch Ruhestrom in Offenstellung gehaltenen Schnellschlußventil, das bei Stromunterbrechung den Speicher gegen die Leitung abschließt, ausgerüstet sind.Safety device to prevent damage in the event of a pipe break in Hydroelectric power plants The invention relates to a safety device for prevention of damage in the event of a pipe burst in hydropower plants, especially those with a Water turbine, a pressure pipe to this, a "water storage tank and a quick-closing valve held in the open position by idle current, which in the event of a power interruption locks the storage tank against the line.

Erfindungsgemäß wird dies dadurch erreicht, . daß ein stromführender Leiter um die Rohrleitung so verlegt ist, daß bei Rohrbruch der Leiter durch die Sprengstücke zerrissen- und dadurch der Strom unterbrochen wird.According to the invention this is achieved by. that a live Head around the pipeline is laid so that in the event of a pipe break, the head through the Explosives are torn up - and the electricity is interrupted as a result.

In den Abb. i und 2 sind Ausführungsbeispiele des Erfindungsgegenstandes dargestellt.In Figs. I and 2 are exemplary embodiments of the subject of the invention shown.

Abb. i zeigt ein Ausführungsbeispiel, bei dem ein stromführender Leitungsdraht b in Abständen in Schnürschlingen c um die Rohrleitung a gelegt ist, wobei die Schnürschlingen die Rohrleitung fest umschließen.Fig. I shows an embodiment in which a live lead wire b is placed at intervals in lace loops c around the pipeline a, the lace loops tightly enclose the pipeline.

In Abb. 2 ist ein Ausführungsbeispief dargestellt, bei dem ein stromführender Leitungsdraht schraubenförmig um die Rohrleitung a gewunden ist, mit der er gegebenenfalls auch noch durch Klemmen d verbunden sein kann.In Fig. 2 an embodiment is shown in which a current-carrying Conductor wire is helically wound around the pipeline a, with which it may be can also be connected by terminals d.

Bei Rohrbruch wird nun durch Reißen des stromführenden Leiters b der Strom unterbrochen und infolgedessen das Schnellschlußventil geschlossen.If the pipe breaks, the current-carrying conductor b is torn The current is interrupted and the quick-acting valve is closed as a result.
