 EMI2.1 
 Verriegelung aufgehoben wird und die Schalter unter der Wirkung der Federn in die punktiert gezeichnete Lage kommen. 



   Tritt aus irgend einer Ursache im   Verteilungssystem   eine abnormale Steigerung bzw. Erniedrigung der Spannung ein, so schliesst die Armatur c den unteren Kontakt h bzw. oberen Kontakt g, wobei der   Elektromagnet k   in beiden Fällen erregt wird und die Schalter o in die punktiert gezeichnete. Lage bringt. Dadurch wird der Schnellregler   A   abgeschaltet und in den Erregerstromkreisen der Erregermaschinen p gerade solche Teile der Widerstände kurzgeschlossen, dass die übrigen, nun dauernd eingeschalteten Teile der Widerstände annähernd den richtigen Wert der Generatorspannung ergeben. 



   Nach Beseitigung des Fehlers im System werden dann die Schalter o mit der Hand wieder in die normale Lage, entgegen der Federwirkung, zurückgebracht und durch die Armatur m verriegelt, wodurch der Schnellregler wieder in Tätigkeit tritt.

 EMI2.1
 The lock is released and the switches come into the position shown in dotted lines under the action of the springs.



   If for any reason an abnormal increase or decrease in voltage occurs in the distribution system, the armature c closes the lower contact h or upper contact g, the electromagnet k being excited in both cases and the switch o in the dotted line. Location brings. As a result, the high-speed regulator A is switched off and in the excitation circuits of the excitation machines p just such parts of the resistors are short-circuited that the remaining, now permanently switched on, parts of the resistors produce approximately the correct value of the generator voltage.



   After the error in the system has been eliminated, the switches o are then manually returned to their normal position, against the action of the spring, and locked by the fitting m, whereby the rapid regulator comes into operation again.

PATENT ANSPRUCH : Sicherheitsvorrichtungjür durch Schnellregler überwachte elektrische Generatoren, dadurch gekennzelchnet, dass ein elektromagnetisches Relais sowohl bei Überschreitung einer zulässigen Maximalspannung als auch bei Unterschreitung einer zulässigen Minimalspannung in dem Ver- teilungasystem den Schnellregler gänzlich abschaltet und in den Erregerkreis, welcher die Spannung des zu regelnden Generators beeinflusst, einen solchen Teil des vom Schnellregler betätigten Widerstandes dauernd einschaltet, dass die Spannung des Generators dadurch annähernd den richtigen Wert annimmt. PATENT CLAIM: Safety device for electrical generators monitored by high-speed regulators, characterized in that an electromagnetic relay completely switches off the high-speed regulator both when a permissible maximum voltage is exceeded and when a permissible minimum voltage is not reached in the distribution system and into the excitation circuit that controls the voltage of the Generator, such a part of the resistor operated by the fast regulator continuously switches on that the voltage of the generator assumes approximately the correct value.
