  Einrichtung zum Schutz der Generatoren elektrischer Zentralen. 



   Die Erfindung bezieht sieh auf einen Generatorsehutz für   elektriseLe   Zentralen : dieser besteht darin, dass in den Feldstromkreis der Erregermaschine an Stelle des bekannten   Feldsel@wächnngswider-   standes oder neben diesem Apparat ein   regulierbarer Widerstand eingesehaltet wird. welcher im no@malen   Betrieb kurzgeschlossen, beim Auftreten von   Störungen   aber   automatisch in Abhängigkeit von dem   bei   Kurzschlüssen   oder sonstigen Betriebsstörungen   auf@etenden   überstrom eingeschaltet wird.

  Device for the protection of the generators of electrical centers.



   The invention relates to a generator protection for electrical centers: this consists in the fact that an adjustable resistance is maintained in the field circuit of the exciter instead of the known field selector or next to this apparatus. which is short-circuited in normal operation, but is switched on automatically in the event of malfunctions depending on the overcurrent occurring in the event of short circuits or other operational malfunctions.



   The invention is shown in the drawing, a denotes the generator. the exciter

 a device is expediently provided by means of which the deactivation of the resistor takes place more slowly. For example, an additional resistor m connected upstream of the armature can be used for this purpose. The circuit can still be simplified and the Feldsehwäehunss's resistance e

 is combined in such a way that the first stages of the shunt regulating resistor d, which are not used during operation, are used as field weaknesses: swidrrstand.



   The arrangement according to the invention is particularly useful in centers where only one
