Description

Schnellschlußregler für elektrische Stromerzeuger antreibende Kraftmaschinen. Durch das Patent 350742 ist ein Schnel_lschlußregler für elektrische Stromerzeuger antreibende Kraftmaschinen, die durch einen in den Hauptstromkreis eingeschalteten Magneten .bei Kurzschluß gegen Durchgehen .gesichert werden, geschützt, bei dem der Magnet während der Stromerzeugung ein Spannwerk o. dgl. in der wirkungslosen Lage hält, das zufolge Aufhören des Stromes freigegeben wird, so daß es das Antriehmittel für die Kraftmaschine plötzlich absperren kann.Trip controller for electric power generators driving engines. The patent 350742 is a quick circuit regulator for electrical power generators driving prime movers, which are switched into the main circuit by a Magnets .are .secured against runaway in the event of a short circuit, protected by the the magnet during power generation a tensioning mechanism or the like in the ineffective Able to stop the current is released, so that it is the drive means can suddenly shut off for the prime mover.

Bei der Erfindung, die einen Schnellschlußregler dieser Art betrifft, der sich durch besondere Einfachheit und, große Betriebssicherheit auszeichnet, ist davon ausgegangen, daß Drehzahlüberschreitungen, die nach: dem Auftreten des Kurzschlusses entstehen., den Kraftmaschinen, z. B. Turbinen, nichts schaden, wohl! dagegen. den angetriebenen Stromerzeugern. Außerdem erfordert das Absperren der Antriebmittel für die Kraftmaschine Sicherheitsvorkehrungen. oder Hilfseinrichtungen bei Wasserturbinen, z. B. besonders anzutreibende Schließvorrichtungen, die bei dem neuen Regler entbehrlich sind.In the invention, which relates to a trip regulator of this type, which is characterized by its particular simplicity and high operational reliability, is assumed that over-revs that occur after: the occurrence of the Short circuit arise., The engines, z. B. Turbines, no harm, well! against it. the powered generators. Also requires locking the Drive means for the prime mover. Safety precautions. or auxiliary equipment in water turbines, e.g. B. specially driven locking devices that are used in are not necessary for the new controller.

Der Schnellschlußregler nach der Erfindung besteht darin, daß das von dem Magneten während der Stromerzeugung in der wirkungslosen Lage gehaltene und zufolge Rufhörens des Stromes .freigegebene Spannwerk den Stromerzeuger von der Kraftmaschine abkuppelt. Beispielsweise kann bei einem von einer Wasserturbine aus mittels eines eine Spannrolle aufweisenden Riementriebes in Gang gesetzten Generator von dem in die Hauptstromleitung geschalteten Magneten ein mit dem Belastungsgewicht der Spannrolle in Verbindung stehender Anker gehalten werden, der nach dem Aufhören des elektrischen Stromes infolge Kurzschlusses herabfällt und das Belastungsgewicht der .Spannrolle mittelbar oder unmittelbar .anhebt, so daß der Übertragungsriemen schlaff wird und der Generator zum Stillstand kommt. Zweckmäßig ist es, in die vom Anker zum Belastungsgewicht der Spannrolle führende Verbindung ein Spannwerk (Kipphebel o. dgl.) oder deren mehrere dinzuschalten, damit das Gewicht des Ankers, das in diesem Fall nur einen Sperrhebel o. dgl. des Spannwerkes auslöst, gering sein kann.The trip regulator according to the invention is that the held in the inoperative position by the magnet during power generation and according to the call hearing of the electricity the engine is uncoupled. For example, one of a water turbine from a generator set in motion by means of a belt drive with a tension pulley from the magnet connected to the main power line with the load weight the tensioning pulley associated anchor to be held after the cessation of the electric current falls as a result of a short circuit and the load weight the .tensioning roller directly or indirectly .lifts so that the transmission belt goes limp and the generator comes to a standstill. It is useful to use the Anchor connection leading to the load weight of the tensioning pulley a tensioning mechanism (rocker arm o. the like) or several of them to be switched on, so that the weight of the anchor, which is in In this case, only one locking lever or the like of the tensioning mechanism triggers, can be low.

Selbstverständlich kann durch das Herabfallen des Ankers auch gleichzeitig eine durch ein Spannwerk o. dgl. zu betätigende Bremse eingerückt werden, die das Stillsetzen des Stromerzeugers beschleunigt.Of course, the dropping of the anchor can also occur at the same time a brake to be actuated by a tensioning mechanism or the like Shutting down the generator accelerates.

Wenn die Fallhöhe des Ankers nur gering gewählt wird, so kann der Magnet nach der Beseitigung des Kurzschlusses beim Wiedereintreten des Stromes in die Wicklung den Anker auch selbsttätig wieder in die unwirksame Lage zurückziehen, so daß das Belastungsgewicbt wieder auf die Spannrolle einwirkt und der Antrieb des Stromerzeugers wiederherg!stellt wird.If the height of fall of the anchor is chosen to be low, the can Magnet after the short-circuit has been eliminated when the current re-enters the winding automatically pulls the armature back into the inoperative position, so that the load weight is back on the tension pulley acts and the drive of the generator is restored.
