Description
Bei elektrisch angetriebenen Schiffen, namentlich solchen mit Dieselmotoren zum Antrieb von Mehrphasengeneratoren, wird die Generatorleistung meistens in mehrere Einheiten unterteilt. Bei kleineren Schiffsgeschwindigkeiten arbeitet dann ein Generator auf den-Propellermotor, bei größeren Schiffsgeschwindigkeiten arbeiten mehrere Generatoren parallel auf den Propellermotor. Beim Übergang von der kleinen Schiffsgeschwindigkeit auf die größere werden die außer Betrieb befindlichen Generatoren zugeschaltet. Es ist nun vorgeschlagen worden, beim Zuschalten alle Generatoren in unerregtem Zustande zusammenzuschalten und sie sodann anzuregen. Mit diesem Verfahren ist aber der Nachteil verbunden, daß während der Zuschaltzeit der Propellermotor spannungslos gemacht wird, so daß er von neuem in Betrieb genommen werden muß. Dieser Nachteil könnte dadurch vermieden werden, daß die neu zuzuschaltenden Generatoren in bekannter Weise mit dem laufenden Generator fein synchronisiert werden. Dieses Verfahren ist jedoch auf Schiffen unbequem, weil es nicht einfach ist, die Drehzahlen der zuzuschaltenden Generatoren der Drehzahl des laufenden Generators anzupassen. Außerdem bedingt dieses Verfahren Leistungsschalter zwischen den Sammelschienen und den Generatoren.For electrically powered ships, especially those with diesel engines To drive multi-phase generators, the generator output is usually divided into several Units divided. A generator then works at lower ship speeds on the propeller motor, several generators work at higher ship speeds parallel to the propeller motor. When transitioning from the low speed of the ship The generators that are not in operation are switched on to the larger one. It has now been proposed that all generators be in the de-energized state when switching on To interconnect states and then to stimulate them. With this procedure is however associated with the disadvantage that the propeller motor is de-energized during the connection time is made so that it has to be put into operation again. This disadvantage could thus be avoided that the new generators to be switched on in known Way to be finely synchronized with the running generator. This procedure is however inconvenient on ships because it is not easy to control the speeds of the to be switched on Adapt generators to the speed of the running generator. In addition, this requires Move circuit breakers between the busbars and the generators.
Nach der Erfindung soll sowohl das Außerbetriebnehmen des Motors als auch das Feinsynchronisieren dadurch vermieden werden, daß die Generatoren offene Sternpunkte erhalten und daß die in Betrieb zu nehmenden Generatoren an diesen Punkten zweckmäßig durch Luftschütze zugeschaltet werden. Durch das Zuschalten im Sternpunkt werden die erforderlichen Abmessungen der Leistungsschalter (Luftschütze) kleiner als bei den bekannten Verfahren.According to the invention, both the shutdown of the engine as fine synchronization can also be avoided by keeping the generators open Obtained star points and that the generators to be put into operation at these points can be switched on appropriately by air contactors. By switching on at the star point the required dimensions of the circuit breakers (air contactors) become smaller than with the known methods.
In der Zeichnung sind zwei Ausführungsbeispiele der Erfindung veranschaulicht. In beiden Fällen wird beim Zuschalten der Generatoren das sogenannte Grobsynchronisieren verwendet. Die Generatoren I, 2 und 3 speisen über die Trennschalter 6; 7, 8 und 9 und die Sammelschienen 4 den Antriebsmotor 5 für die Propellerwelle eines Schiffes. Die Sternpunkte der Generatoren sind offen und können in beiden Fällen durch Schütze Io, II und I2 geschlossen werden. In der in Fig. I dargestellten Schaltung ist außerdem noch eine Drossel 13 vorgesehen, die an Sammelschienen I4 angeschlossen ist, mit denen die offenen Sternpunkte der drei Generatoren durch Trennschalter I5, 16 und 17 verbunden sind. Die Drossel dient zum Grobsynchronisieren der jeweils zuzuschaltenden Generatoren. Angenommen, die Generatoren 2 und 3 sind mit dem Motor zusammengeschaltet und der Generator I soll zugeschaltet werden, dann brauchen die Sammelschienen 4 nicht spannungslos gemacht zu werden, sondern die Trennschalter 6 und 15 werden, nachdem der Generator I durch seine Antriebsmaschine hochgefahren ist, einfach eingelegt und darauf wird der Sternpunkt der Drossel 13 durch das Schütz 18 geschlossen, das kleiner ausfällt als bei dem genannten Verfahren verwendete Leistungsschalter. Nachdem der Generator I sich gefangen hat, wird auch das Schütz Io geschlossen. Der Trennschalter 15 kann dann wieder geöffnet werden.Two exemplary embodiments of the invention are illustrated in the drawing. In both cases, what is known as coarse synchronization is used when the generators are switched on used. The generators I, 2 and 3 feed through the disconnector 6; 7, 8 and 9 and the busbars 4 the drive motor 5 for the propeller shaft of a ship. The star points of the generators are open and in both cases can be through contactors Io, II and I2 are closed. In the circuit shown in Fig. I is also a choke 13, which is connected to busbars I4, is also provided where the open star points of the three generators are connected to circuit breakers I5, 16 and 17 are connected. The throttle is used for coarse synchronization of the respectively to be switched on Generators. Assume generators 2 and 3 are interconnected with the engine and the generator I is to be switched on, then the busbars need 4 not to be de-energized, but the disconnectors 6 and 15 are, after the generator I has started up by its prime mover, simply inserted and then the star point of the choke 13 is closed by the contactor 18, the is smaller than the circuit breaker used in the process mentioned. After this the generator I has caught, the contactor Io is also closed. The circuit breaker 15 can then be opened again.
In der in Fig.2 dargestellten Schaltung wird für den gleichen Fall, daß die Generatoren 2 und 3 bereits mit dem Motor zusammengeschaltet sind, und der Generator I zugeschaltet werden soll, zuerst der Schalter 6 eingelegt und darauf das Schütz Io geschlossen. Der Generator fährt dann unerregt mit Hilfe seiner Dämpferwicklung asynchron hoch.In the circuit shown in Fig. 2, for the same case, that the generators 2 and 3 are already connected to the engine, and the Generator I is to be switched on, first the switch 6 is inserted and then the contactor Io closed. The generator then runs in an unexcited state with the help of its damper winding asynchronously high.
