Abstract
Description
Die Erfindung betrifft eine Antriebseinheit, insbesondere für ein Schienenfahrzeug, mit zumindest einer ersten Motoreinheit, wenigstens einer ersten Leistungserzeugungseinheit zur Erzeugung einer elektrischen Leistung für die erste Motoreinheit und einer ersten Motorschützeinheit, die dazu vorgesehen ist, eine erste, zwischen der ersten Motoreinheit und der ersten Leistungserzeugungseinheit hergestellte, mehrphasig ausgebildete elektrische Verbindung zumindest teilweise zu unterbrechen. The invention relates to a drive unit, in particular for a rail vehicle, with at least one first motor unit, at least one first power generation unit for generating an electrical power for the first motor unit and a first motor contactor unit, which is provided, a first, between the first motor unit and the first Power generating unit produced, multi-phase electrical connection formed at least partially interrupt.
Es sind bereits Antriebseinheiten vorgeschlagen worden, bei welchen eine Motoreinheit von einer zugeordneten Leistungserzeugungseinheit mittels eines Motorschützes bei Bedarf getrennt werden kann. Dieses dient zum Schutz der Leistungserzeugungseinheit gegen Überspannungen, die bei einem Betrieb der Motoreinheit mit hohen Drehzahlen und Feldschwächung von dieser erzeugt werden können. Bei einem unerwünschten Fehlerfall in der Leistungserzeugungseinheit, insbesondere bei einer fehlerbedingten, dauerhaft leitenden Verbindung an einer Fehlerstelle, kann außerdem durch das Motorschütz ein Energieeintrag in die Fehlerstelle vermieden werden. Drive units have already been proposed in which a motor unit can be disconnected from an associated power generation unit by means of a motor contactor if required. This serves to protect the power generation unit against overvoltages which can be generated by the motor unit at high speeds and field weakening during operation thereof. In the event of an undesired fault in the power generation unit, in particular in the case of an error-related, permanently conductive connection at a fault location, an energy input into the fault location can also be avoided by the motor contactor.
Der Erfindung liegt die Aufgabe zugrunde, eine gattungsgemäße Antriebseinheit bereitzustellen, bei welcher der Schutz der zumindest einen Leistungserzeugungseinheit weiter gesteigert werden kann. The invention has for its object to provide a generic drive unit, in which the protection of at least one power generation unit can be further increased.
Hierzu wird vorgeschlagen, dass die erste Motorschützeinheit zumindest zwei Trenneinheiten umfasst, die jeweils mindestens ein Trennmittel zur Trennung einer Phase der ersten elektrischen Verbindung aufweisen, wobei die Trennmittel hinsichtlich eines Betätigungsvorgangs voneinander entkoppelt sind. Hierdurch kann ein höherer Schutz der zumindest einen Leistungserzeugungseinheit, insbesondere hinsichtlich eines Defekts einer Trenneinheit der Motorschützeinheit, erreicht werden. For this purpose, it is proposed that the first motor contactor unit comprises at least two isolating units, each having at least one separating means for separating a phase of the first electrical connection, wherein the separating means are decoupled from each other with respect to an actuating operation. In this way, a higher protection of the at least one power generation unit, in particular with regard to a defect of a separation unit of the motor contactor unit, can be achieved.
Dies eignet sich insbesondere für eine Ausführung der Antriebseinheit, bei welcher die zumindest eine Motoreinheit als permanent erregte Synchronmaschine ausgebildet ist. Bezieht die Leistungserzeugungseinheit elektrische Energie aus einem Zwischenkreis mit definierter und stabiler Spannung, insbesondere aus einem Gleichspannungszwischenkreis, kann ein Betrieb der Synchronmaschine mit hohen Drehzahlen hohe Spannungen erzeugen, die die Zwischenkreisspannung erheblich übertreffen. Hierbei kann ein hoher Energiefluss von der Motoreinheit durch die Leistungserzeugungseinheit in den Zwischenkreis gelangen. Die kann zu starken Beanspruchungen bis zur Zerstörung der Leistungserzeugungseinheit führen. This is particularly suitable for an embodiment of the drive unit, in which the at least one motor unit is designed as a permanently excited synchronous machine. If the power generating unit draws electrical energy from an intermediate circuit with a defined and stable voltage, in particular from a DC voltage intermediate circuit, operation of the synchronous machine at high rotational speeds can generate high voltages which considerably exceed the intermediate circuit voltage. In this case, a high energy flow from the motor unit through the power generation unit can get into the DC link. This can lead to heavy loads until the destruction of the power generation unit.
Ferner eignet sich die vorgeschlagene Antriebseinheit für eine Anwendung als Schienenfahrzeugsantriebseinheit, die zum Antreiben zumindest einer Antriebsachse eines Schienenfahrzeugs vorgesehen ist. Bei einer Ausbildung der zumindest einen Motoreinheit als permanent erregte Synchronmaschine induziert eine Rotation der Antriebsachse stets eine Spannung an Klemmen der mit der Antriebsachse gekoppelten Motoreinheit. Es kann, solange die elektrische Verbindung der Motoreinheit zur zugeordneten Leistungserzeugungseinheit das Fließen eines elektrischen Stroms erlaubt, ein elektrischer Strom bis zu einem Stillstand des Schienenfahrzeugs in die Leistungserzeugungseinheit fließen. Durch die Motorschützeinheit kann die elektrische Verbindung – bevor der Stillstand erreicht wird – derart teilweise unterbrochen werden, dass sie ein Fließen eines elektrischen Stroms nicht zulässt. Furthermore, the proposed drive unit is suitable for use as a rail vehicle drive unit, which is provided for driving at least one drive axle of a rail vehicle. In a configuration of the at least one motor unit as a permanently excited synchronous machine, a rotation of the drive axle always induces a voltage at terminals of the motor unit coupled to the drive axle. As long as the electrical connection of the motor unit to the associated power generating unit allows the flow of electrical current, electrical current can flow into the power generating unit until the rail vehicle stops. By the motor contactor unit, the electrical connection - before the standstill is reached - be so partially interrupted that it does not allow a flow of electrical current.
Unter einem „zumindest teilweisen Unterbrechen“ einer mehrphasigen Verbindung soll insbesondere ein Vorgang verstanden werden, bei welchem für zumindest eine Untergruppe der Phasen der elektrischen Verbindung eine Trennung der Motoreinheit von der Leistungserzeugungseinheit derart erfolgt, dass ein zwischen der Motoreinheit und der Leistungserzeugungseinheit fließender Leistungsfluss, insbesondere ein fließender elektrischer Strom unterbrochen wird. Dies kann dadurch erreicht werden, dass – bei einer Ausbildung der elektrischen Verbindung mit N Phasen – eine Trennung für zumindest N-1 Phasen erfolgt. An "at least partial interruption" of a multiphase connection is to be understood in particular to mean a process in which the motor unit is disconnected from the power generation unit for at least one subgroup of phases of the electrical connection such that a power flow flowing between the motor unit and the power generation unit, in particular a flowing electric current is interrupted. This can be achieved in that - with a formation of the electrical connection with N phases - a separation takes place for at least N-1 phases.
Die Trennmittel unterschiedlicher Trenneinheiten sind zweckmäßigerweise hinsichtlich eines Betätigungsvorgangs dadurch voneinander entkoppelt, dass zumindest auf eine mechanische Kopplung dieser Trennmittel, welche insbesondere zu einer synchronen Betätigung der Trennmittel dient, verzichtet wird. The separating means of different separating units are expediently decoupled from each other in terms of an actuating operation, that at least on a mechanical coupling of this release agent, which serves in particular for a synchronous actuation of the release agent, is dispensed with.
In einer Ausgestaltung der Erfindung umfasst zumindest eine der Trenneinheiten einen Satz von mehreren, mechanisch miteinander gekoppelten Trennmitteln. Hierdurch können, zumindest für eine der Trenneinheiten, gängige mehrphasige Schalter eingesetzt werden. Die Trennmittel sind hierbei vorzugsweise derart miteinander mechanisch gekoppelt, dass aufgrund der mechanischen Kopplung ein auf die Trenneinheit wirkender Auslösevorgang einer Auslöseeinheit eine synchrone Betätigung, insbesondere ein synchrones Schließen bzw. ein synchrones Öffnen der Trennmittel bewirkt. In one embodiment of the invention, at least one of the separation units comprises a set of a plurality of separation means mechanically coupled together. As a result, common multiphase switches can be used, at least for one of the separation units. In this case, the separating means are preferably mechanically coupled to one another in such a way that, due to the mechanical coupling, a triggering unit acting on the separating unit causes a synchronous actuation, in particular a synchronous closing or a synchronous opening of the separating means.
Es kann außerdem eine besonders hohe Redundanz in der Ausführung der Motorschützeinheit erreicht werden, wenn die Trenneinheiten jeweils einen Satz von mehreren, mechanisch miteinander gekoppelten Trennmitteln umfassen. In addition, a particularly high degree of redundancy in the design of the motor contactor unit can be achieved if the isolating units each comprise a set of a plurality of mechanically mutually coupled separating means.
In diesem Zusammenhang können ferner Bauteile und Kosten eingespart werden, wenn die Trenneinheiten jeweils eine unterschiedliche Anzahl von Trennmitteln aufweisen. Hierbei kann die Anzahl der Trennmittel derart gewählt werden, dass eine Redundanz lediglich für eine Mindestanzahl von Phasen gegeben ist, deren Trennung für ein Unterbrechen eines Leistungsflusses unerlässlich ist. In this context, further components and costs can be saved if the separation units each have a different number of release agents. In this case, the number of separating means can be chosen such that a redundancy is given only for a minimum number of phases, the separation of which is essential for interrupting a power flow.
In einer besonderen Ausführung der Erfindung weist zumindest eine der Trenneinheiten ein Trennmittel für jede Phase der ersten elektrischen Verbindung auf, wodurch für diese zumindest eine Trenneinheit ein besonders gängiger, allphasiger Schalter eingesetzt werden kann. In a particular embodiment of the invention, at least one of the separation units has a release agent for each phase of the first electrical connection, whereby a particularly common, all-phase switch can be used for this at least one separation unit.
Gemäß einer weiteren Ausführungsform der Erfindung wird vorgeschlagen, dass die Trenneinheiten die gleiche Anzahl von Trennmitteln aufweisen, wobei die Anzahl kleiner als die Phasenanzahl der ersten elektrischen Verbindung ist und die Trenneinheiten jeweils Trennmittel für eine unterschiedliche Gruppe von Phasen umfassen. Hierdurch kann eine konstruktiv einfache Ausführung der Motorschützeinheit erreicht werden, bei welcher die Trenneinheiten vorteilhaft identisch zueinander ausgeführt sind und sich die Anzahl der Trennmittel in jeder Trenneinheit auf die zur Unterbrechung eines Leistungsflusses notwendige Mindestanzahl von zu trennenden Phasen beschränkt. Durch ein Zusammenwirken der Trenneinheiten ist vorteilhafterweise für jede Phase der ersten elektrischen Verbindung zumindest ein Trennmittel vorgesehen. Die unterschiedlichen Gruppen von Phasen, die den Trenneinheiten zugeordnet sind, können sich überlappen, wodurch für zumindest eine Phase zumindest zwei Trennmittel vorgesehen sind. According to a further embodiment of the invention, it is proposed that the separating units have the same number of separating means, the number being smaller than the number of phases of the first electrical connection and the separating units each comprising separating means for a different group of phases. In this way, a structurally simple embodiment of the motor contactor unit can be achieved, in which the separation units are advantageously designed identical to one another and the number of release agents in each separation unit is limited to the minimum number of phases to be disconnected for interrupting a power flow. By an interaction of the separation units, at least one release agent is advantageously provided for each phase of the first electrical connection. The different groups of phases, which are assigned to the separation units, may overlap, whereby at least two release agents are provided for at least one phase.
In einer weiteren Ausgestaltung der Erfindung ist jeder Phase der ersten elektrischen Verbindung jeweils eine unterschiedliche Trenneinheit der ersten Motorschützeinheit zugeordnet, wobei die Trenneinheiten jeweils ein einziges Trennmittel aufweisen. Hierdurch können eine besonders konstruktiv einfache Ausführung der Motorschützeinheit mit einer geringen Anzahl von Trennmitteln und jedoch ein zuverlässiger Schutz erreicht werden. In dieser Ausführung kann insbesondere eine Konfiguration erreicht werden, in welcher für jede Phase der ersten elektrischen Verbindung entlang dieser jeweils ausschließlich ein Trennmittel vorgesehen ist. In a further embodiment of the invention, each phase of the first electrical connection is assigned in each case a different separation unit of the first motor protection unit, wherein the separation units each have a single release agent. As a result, a particularly structurally simple design of the motor contactor unit with a small number of release agents and, however, a reliable protection can be achieved. In this embodiment, in particular, a configuration can be achieved, in which for each phase of the first electrical connection along this in each case only one release agent is provided.
In einer bevorzugten Ausbildung der Erfindung weist die erste Motorschützeinheit eine Steuereinheit und Auslöseinheiten auf, die jeweils einer unterschiedlichen Trenneinheit zugeordnet und zum Auslösen eines Betätigungsvorgangs der zugeordneten Trenneinheit auf der Basis eines von der Steuereinheit ausgegebenen Steuersignals vorgesehen sind, wobei die Auslöseeinheiten jeweils mit einem unterschiedlichen Ausgang der Steuereinheit in Wirkverbindung stehen. Hierdurch kann zusätzlich zu einer mechanischen Entkopplung der Trennmittel unterschiedlicher Trenneinheiten voneinander eine weitere Unabhängigkeit dieser Trennmittel hinsichtlich der Steuerung erreicht werden. Die Auslöseeinheiten sind insbesondere dazu vorgesehen, auf der Basis eines von der Steuereinheit erzeugten Steuersignals eine Bewegung des zumindest einen Trennmittels der zugeordneten Trenneinheit auszulösen. Die Verbindung der Auslöseeinheiten mit den Ausgängen der Steuereinheit erfolgt vorteilhafterweise über zwei voneinander getrennte Signalwege, die zur Führung des jeweiligen Steuersignals vorgesehen sind. In a preferred embodiment of the invention, the first motor contactor unit comprises a control unit and tripping units, each associated with a different disconnecting unit and provided for triggering an actuating operation of the associated disconnecting unit on the basis of a control signal issued by the control unit, the tripping units each having a different output the control unit are in operative connection. In this way, in addition to a mechanical decoupling of the release agent of different separation units from each other, a further independence of these release agents with respect to the control can be achieved. The tripping units are in particular designed to trigger a movement of the at least one separating means of the associated separating unit on the basis of a control signal generated by the control unit. The connection of the trip units with the outputs of the control unit is advantageously carried out via two separate signal paths, which are provided for guiding the respective control signal.
Weist die Antriebseinheit zumindest eine zweite Motoreinheit, wenigstens eine zweite Leistungserzeugungseinheit zur Erzeugung einer elektrischen Leistung für die zweite Motoreinheit und eine zweite Motorschützeinheit auf, die dazu vorgesehen ist, eine zweite, zwischen der zweiten Motoreinheit und der zweiten Leistungserzeugungseinheit hergestellte elektrische Verbindung zumindest teilweise zu unterbrechen, welche mehrphasig ausgebildet ist, wird vorgeschlagen, dass die zweite Motorschützeinheit zumindest zwei Trenneinheiten umfasst, die jeweils mit einer korrespondierenden Trenneinheit der ersten Motorschützeinheit mechanisch gekoppelt sind. Durch diese mechanische Kopplung von Trenneinheiten unterschiedlicher Motorschützeinheiten kann der durch die Ausbildung der ersten Motorschützeinheit erhöhte Schutz konstruktiv einfach auf die zumindest zweite Motorschützeinheit erweitert werden. Die gebildeten Sätze von korrespondierenden Trenneinheiten der unterschiedlichen Motorschützeinheiten sind vorteilhaft voneinander zumindest mechanisch entkoppelt. Außerdem können diese Sätze besonders vorteilhaft jeweils mittels einer separaten Auslöseinheit betätigt werden und daher steuertechnisch voneinander entkoppelt sein. Does the drive unit at least a second motor unit, at least a second power generation unit for generating an electric power for the second motor unit and a second motor contactor, which is intended to at least partially interrupt a second, established between the second motor unit and the second power generation unit electrical connection , which is formed polyphase, it is proposed that the second motor contactor comprises at least two separation units, which are each mechanically coupled to a corresponding separation unit of the first motor contactor. Due to this mechanical coupling of separating units of different motor contactor units, the increased protection afforded by the design of the first motor contactor unit can be structurally easily extended to the at least second motor contactor unit. The formed sets of corresponding separation units of the different motor contactor units are advantageously at least mechanically decoupled from one another. In addition, these sets can be operated particularly advantageous in each case by means of a separate tripping unit and therefore be decoupled tax technology from each other.
Es kann in diesem Zusammenhang eine besonders kostengünstige Ausgestaltung der ersten und zweiten Motorschützeinheit bereitgestellt werden, wenn jeder Phase der ersten elektrischen Verbindung jeweils eine Trenneinheit der ersten Motorschützeinheit zugeordnet ist, wobei die Trenneinheiten jeweils ein einziges Trennmittel aufweisen, und wenn ferner jeder Phase der zweiten elektrischen Verbindung jeweils eine unterschiedliche Trenneinheit der zweiten Motorschützeinheit zugeordnet ist, wobei die Trenneinheiten der zweiten Motorschützeinheit jeweils ein einziges Trennmittel aufweisen. In dieser Ausführung werden vorteilhaft einzelne, jeweils zu unterschiedlichen Motorschützeinheiten gehörende Trennmittel mechanisch miteinander gekoppelt. Ferner kann eine Konfiguration erreicht werden, bei welcher für jede Phase der zweiten elektrischen Verbindung entlang dieser ausschließlich ein Trennmittel vorgesehen ist. In this context, a particularly cost-effective embodiment of the first and second motor contactor unit can be provided if each phase of the first electrical connection is assigned in each case to a separation unit of the first motor contactor unit, the isolation units each having a single isolating means, and furthermore if each phase of the second electrical contactor Connection is assigned in each case a different separation unit of the second motor contactor, wherein the separation units of the second motor contactor each having a single release agent. In this embodiment, individual separating means belonging to different motor contactor units are advantageously mechanically coupled to one another. Furthermore, a configuration can be achieved in which for each phase of the second electrical connection along this only a release agent is provided.
