Description

Die Erfindung betrifft eine Energieversorgungsanlage zur Verwendung im Bereich einer dieselelektrischen Lokomotive, die einen Generator aufweist, der von einem Dieselmotor angetrieben ist und der einen Gleichstromzwischenkreis zur Speisung einer Traktionseinrichtung versorgt und die mit einer Kopplungseinrichtung zur Speisung von Verbrauchern versehen ist, die im Bereich von Reisezugwagen angeordnet sind. Für die Versorgung der Reisezugwagen mit elektrischer Energie wird auf Diesellokomotiven eine derartige Energieversorgungsanlage vorgesehen. Die Energieversorgungsanlage gibt beispielsweise eine Spannung von 1000 V und 16 2/3 Hz über eine durchgehende Zugsammelschiene an die Reisezugwagen ab.The invention relates to an energy supply system for use in the field of a diesel-electric locomotive, which has a generator which is driven by a diesel engine and which supplies a direct current intermediate circuit for supplying a traction device and which is provided with a coupling device for supplying consumers in the area of passenger cars are arranged. Such an energy supply system is provided on diesel locomotives for supplying the passenger coaches with electrical energy. The power supply system, for example, outputs a voltage of 1000 V and 16 2/3 Hz to the passenger cars via a continuous train busbar.
Durch die Elektrifizierung in Europa sind folgende Spannungen auf der durchgehenden Zugsammelschiene vorgegeben: 1000 V, 16 2/3 Hz, 1500 V, 50 Hz, 1500 V Gleichspannung und 3000 V Gleichspannung.Due to the electrification in Europe, the following voltages are specified on the continuous train busbar: 1000 V, 16 2/3 Hz, 1500 V, 50 Hz, 1500 V DC and 3000 V DC.
Die Spannung 1000 V, 16 2/3 Hz wird bei einem Antrieb der Reisezugwagen mit einer Elektrolokomotive über einen Transformator vorgegeben. Die Energieversorgungsanlage auf der Diesellokomotive muß dann auch diese Spannung erzeugen, um die dafür ausgelegten elektrischen Anlagen in den Reisezugwagen zu versorgen.The voltage 1000 V, 16 2/3 Hz is specified when the passenger coaches are driven by an electric locomotive via a transformer. The energy supply system on the diesel locomotive must then also generate this voltage in order to supply the electrical systems designed for this purpose in the passenger coaches.
Ein bekanntes Ausführungsbeispiel ist, daß parallel aus dem Gleichspannungszwischenkreis der Traktionseinrichtung über einen Wechselrichter und einen Transformator 1000 V, 16 2/3 Hz an die Zugsammelschiene abgegeben werden. Der Gleichspannungszwischenkreis wird dabei von einem Drehstromgenerator und einem Gleichrichter gebildet, wobei der Drehstromgenerator vom Dieselmotor angetrieben wird.A known embodiment is that 1000 V, 16 2/3 Hz are output in parallel from the DC voltage intermediate circuit of the traction device via an inverter and a transformer to the train busbar. The DC voltage intermediate circuit is formed by a three-phase generator and a rectifier, the three-phase generator being driven by the diesel engine.
Die Kennlinie des Dieselmotors gibt für den Generator eine Drehzahl von 750 U/min bis 1350 U/min vor. Die Spannung nach Gleichrichtung im Gleichstromzwischenkreis ändert sich dadurch zwischen 1000 V und 1800 V.The characteristic curve of the diesel engine specifies a speed of 750 rpm to 1350 rpm for the generator. The voltage after rectification in the DC link changes between 1000 V and 1800 V.
Der Wechselrichter für die Versorgung der Reisezugwagen wird bei der bekannten Schaltung über die zur Durchführung einer Anschnittsteuerung verwendeten GTO’s so getaktet, daß der Effektivwert der Spannung am Ausgang 1000 V. ist. Das führt dazu, daß das Verhältnis von Arbeitszeit zur Pausenzeit verändert werden muß. Um die elektrischen Anlagen in Reisezugwagen zu betreiben, ist in der Vorschrift UIC 626 vorgegeben, daß die Ausgangsspannung als Block mit 28 ms Arbeitszeit und 2 ms Pausenzeit ausgelegt wird. Diese Bedingung kann mit der bekannten Ausführung nicht erreicht werden.The inverter for the supply of the passenger coaches is clocked in the known circuit via the GTOs used to carry out a gate control so that the effective value of the voltage at the output is 1000 V. This means that the ratio of working hours to break times has to be changed. In order to operate the electrical systems in passenger coaches, regulation UIC 626 stipulates that the output voltage is designed as a block with 28 ms working time and 2 ms break time. This condition cannot be achieved with the known design.
Außerdem ist aus Isolationsgründen ein Trenntransformator für 1000 V, 16 2/3 Hz einzubringen, und zwar für die gesamte Leistung, z. B. 800 kVA für den Betrieb von 14 Reisezugwagen. Der Transformator, der hierzu mit einer Frequenz von 16 2/3 Hz ausgelegt ist, bringt dabei ein erhebliches Gewicht und Bauvolumen auf die Lokomotive.In addition, an isolation transformer for 1000 V, 16 2/3 Hz must be installed for insulation reasons, for the entire output, e.g. B. 800 kVA for the operation of 14 passenger coaches. The transformer, which is designed for this with a frequency of 16 2/3 Hz, brings a considerable weight and volume to the locomotive.
Aufgabe der vorliegenden Erfindung ist es daher, eine Energieversorgungsanlage der einleitend genannten Art derart zu konstruieren, daß ein einfacher Aufbau und ein einfacher Betrieb ermöglicht wird.The object of the present invention is therefore to construct a power supply system of the type mentioned in the introduction in such a way that simple construction and simple operation are made possible.
Diese Aufgabe wird erfindungsgemäß dadurch gelöst, dass die Kopplungseinrichtung einen die Verbraucher speisenden Wechselrichter aufweist, der mit einem ausschließlich dem Wechselrichter zugeordneten Gleichrichter verbunden ist, der an den Generator angeschlossen ist.This object is achieved according to the invention in that the coupling device has an inverter which feeds the loads and is connected to a rectifier which is exclusively assigned to the inverter and is connected to the generator.
Durch diese Ausbildung ist es möglich, eine Speisung der Verbraucher im Bereich der Reisezugwagen unabhängig von den jeweiligen Betriebsbedingungen im Bereich des Gleichstromzwischenkreises vorzunehmen. Darüber hinaus ist es möglich, daß der Trenntransformator für 1000 V, 16 2/3 Hz entfallen kann.This design makes it possible to supply the consumers in the area of the passenger coaches independently of the respective operating conditions in the area of the DC link. It is also possible that the isolating transformer for 1000 V, 16 2/3 Hz can be omitted.
Eine völlige Trennung der der Traktionseinrichtung zugeordneten elektrischen Komponenten und der den zu versorgenden Verbrauchern zugeordneten Komponenten kann dadurch erfolgen, daß der Generator für die Traktionseinrichtung eine zweite Wicklung hat und der Wechselrichter von dieser Wicklung über einen steuerbaren Gleichrichter mit konstanter Spannung versorgt wird und daß der Wechselrichter getaktet wird.A complete separation of the electrical components assigned to the traction device and the components assigned to the consumers to be supplied can take place in that the generator for the traction device has a second winding and the inverter is supplied with constant voltage by this winding via a controllable rectifier and in that the inverter is clocked.
Zur Erfüllung typischer Einsatzanforderungen wird vorgeschlagen, daß eine Blockbildung der Ausgangsspannung bei 16 2/3 Hz von 28 ms Arbeitszeit und 2 ms Pausenzeit erfolgt.To meet typical application requirements, it is proposed that the output voltage be blocked at 16 2/3 Hz of 28 ms working time and 2 ms pause time.
Eine Verwendung eines konventionellen Generators kann dadurch erfolgen, daß eine Drehstromspannung für die Traktionseinrichtung parallel auf einen Trenntransformator 2A conventional generator can be used in that a three-phase voltage for the traction device is connected in parallel to an isolating transformer 2
