  Einrichtung zum Bremsen elektrischer Maschinen, welche durch Wärmekraftmaschinen angetrieben abwechselnd Energie abgeben und aufnehmen. 



   Vorliegende Erfindung betritt eine Einrichtung zum Bremsen in solchen elektrischen Betrieben, in denen die zur Stromerzeugung bestimmte Maschine abwechselnd Energie abgibt und aufnimmt und ihren Antrieb durch eine Wärmekraftmaschine erhält. In Betrieben dieser Art lassen sich durch Anwendung der vorliegenden Einrichtung wesentlich technische und wirtschaftliche Vorteile erzielen. Die Erfindung macht von der bekannten Einrichtung Gebrauch, eine Verbrennungskraftmaschine dadurch zu bremsen, dass man sie als Pumpe wirken   lässt.   



   Die Einrichtung nach der Erfindung besteht nun darin, dass man in den Perioden, in   welchen   die als Stromerzeuger bestimmte elektrische Maschine von den beim Bremsen als Stromerzeuger wirkenden Elektromotoren Energie aufnimmt, diese Energie nicht wie bis dahin üblich in besonderen elektrischen   Bremswiderständen vernichten, sondern von   der zur Stromerzeugung bestimmten Maschine unmittelbar an die mit ihr gekuppelte Wärmekraftmaschine abgehen und in dieser als Luftpumpenarbeit vernichten lässt. 



   Anlagen, die nach dieser Einrichtung betrieben werden. erhalten gleichzeitig eineEinrichtung, welche darin besteht, dass der Steuermechanismus der Wärmekraft maschine unter dem Einfluss der beim   Bremsen   der Elektromotoren eintretenden Änderungen der elektrischen Verhältnisse   selbsttätig, z.   B.   durch   Relais, die auf Ventile wirken, für   den Luftpumpenbetrieb umgestellt   wird. Dabei kann gleichzeitig eine Regelung der Bremsarbeit dadurch erzielt werden, dass man die Kompression der Wärmekraftmaschine selbsttätig oder von Hand entsprechend einstellen lässt.

  Device for braking electrical machines which, driven by heat engines, alternately emit and absorb energy.



   The present invention relates to a device for braking in such electrical plants in which the machine intended for generating electricity alternately emits and absorbs energy and is driven by a heat engine. In companies of this type, significant technical and economic advantages can be achieved by using the present device. The invention makes use of the known device for braking an internal combustion engine by letting it act as a pump.



   The device according to the invention consists in the fact that in the periods in which the electrical machine intended as a power generator takes up energy from the electric motors acting as a power generator during braking, this energy is not destroyed in special electrical braking resistors, as was customary up to then, but by the The machine intended to generate electricity goes directly to the heat engine coupled to it and can be destroyed in it as air pump work.



   Systems that are operated according to this facility. receive at the same time a device, which consists in that the control mechanism of the heat engine under the influence of the changes in electrical conditions occurring when braking the electric motors, e.g. B. by relays that act on valves, is switched for air pump operation. At the same time, the braking work can be regulated by letting the compression of the heat engine be adjusted automatically or by hand.
