Description

Die Erfindung betrifft eine Motorbremse für ein elektrisch angetriebenes Fahrzeug, insbesondere für ein Schienenfahrzeug, mit einer permanent erregten Synchronmaschine, wobei Klemmen der Synchronmaschine über Schalter mit Bremswiderständen in Verbindung stehen.The The invention relates to a motor brake for an electrically driven Vehicle, especially for a rail vehicle, with a permanent magnet synchronous machine, being terminals of the synchronous machine via switches with braking resistors in Connection stand.

Der Schalter kann auch eine Schalterkombination oder ein Umschalter sein.Of the Switch can also be a switch combination or a switch be.

Aus der DE 101 60 612 A1 ist ein Traktionsantrieb bekannt, bei dem einer permanent erregten Synchronmaschine ein Traktionsstromumrichter vorgeschaltet ist. Zwischen dem Traktionsstromumrichter und der Synchronmaschine befindet sich ein Umschalter, durch den die Klemmen der Synchronmaschine wahlweise mit dem Traktionsstromumrichter oder mit den Bremswiderständen verbunden werden können.From the DE 101 60 612 A1 is a traction drive known in which a permanent-magnet synchronous machine, a traction current converter is connected upstream. Between the Traktionsstromumrichter and the synchronous machine is a switch, by which the terminals of the synchronous machine can be optionally connected to the Traktionsstromumrichter or with the braking resistors.

Ein Abbremsen des Fahrzeugs mit der Motorbremse erfolgt dadurch, dass sich der Läufer der permanent erregten Synchronmaschine, so lange sich das Fahrzeug weiter bewegt, dreht. Dabei wird in die Ständerwicklungen eine Spannung induziert. Im Ständerstromkreis angeordnete Bremswiderstände erzeugen dann ein Bremsmoment, das auf den Läufer wirkt. Die permanent erregte Synchronmaschine arbeitet dann als Generator.One Braking the vehicle with the engine brake takes place in that the runner the permanent-magnet synchronous machine, as long as the vehicle keeps moving, turns. In this case, a voltage is in the stator windings induced. In the stator circuit generate arranged braking resistors then a braking torque that acts on the runner. The permanently excited Synchronous machine then works as a generator.

Da der Traktionsstromumrichter, der einen Pulsstromumrichter umfasst, mittels des Umschalters abgetrennt ist, sind störende Einwirkungen des Pulsstromumrichters ausgeschlossen.There the traction current converter comprising a pulse-current converter, is separated by the switch, are disturbing effects of the pulse current inverter locked out.

Beim Bekannten sind die Bremswiderstände, von denen jeweils einer mit den drei Phasen der Synchronmaschine verbunden ist, elektrisch im Stern geschaltet.At the Known are the braking resistors, from each one connected to the three phases of the synchronous machine is, electrically connected in the star.

Eine solche Sternschaltung verursacht schon bei einer Unterbrechung von nur einer Leitung eine relativ große Verminderung der Bremsleistung. Falls nur eine Leitungsverbindung an einem der Bremswiderstände defekt ist, stehen bereits nur noch 50 % der Bremsleistung zur Verfügung.A such star connection already causes an interruption of only one line a relatively large reduction in braking power. If only one line connection on one of the brake resistors is defective is already available, only 50% of the braking power available.

Der Erfindung liegt die Aufgabe zugrunde, eine Motorbremse für ein elektrisch angetriebenes Fahrzeug anzugeben, bei der, falls die elektrische Verbindung zu einem der Bremswiderstände unterbrochen ist, trotzdem noch mindestens zwei Drittel der Bremsleistung zur Verfügung stehen.Of the Invention is based on the object, a motor brake for an electric indicate powered vehicle, in which, if the electrical connection to one of the braking resistors is still interrupted, but still at least two-thirds of the braking power to disposal stand.

Die Aufgabe wird gemäß der Erfindung dadurch gelöst, dass die Bremswiderstände im Dreieck geschaltet sind.The Task is according to the invention solved by that the braking resistors are connected in a triangle.

Damit wird der Vorteil erzielt, dass eine deutlich zuverlässigere Motorbremse zur Verfügung steht als bisher. Darüber hinaus kommt die Motorbremse nach der Erfindung bei hoher Zuverlässigkeit mit vergleichsweise wenigen Bauteilen aus, was auch darauf zurückzuführen ist, dass die permanent erregte Synchronmaschine im Vergleich zu einer Asynchronmaschine keine Kondensatorbatterie benötigt. Aufgrund der vergleichsweise wenigen Bauteile kann es in einem Fahrzeug, das Erschütterungen ausgesetzt ist, weniger oft zu Schäden kommen.In order to the advantage is achieved that a much more reliable Engine brake available stands as before. About that In addition, the engine brake according to the invention comes with high reliability with comparatively few components, which is also due to that the permanently excited synchronous machine compared to a Asynchronous machine no capacitor bank needed. Because of the comparatively Few components can cause it in a vehicle that shakes exposed to less damage.

Alternativ zu einer Dreiecksschaltung könnten bei einer Sternschaltung die Sternpunkte der Maschine und der Bremswiderstände mit einer zusätzlichen Leitung verbunden sein. Zusätzlich könnten auch die Verbindungen, Schalter und Widerstände redundant aufgebaut sein. Beide Alternativen würden aber einen zusätzlichen apparativen Aufwand bedeuten.alternative could turn into a triangle with a star connection, the star points of the machine and the braking resistors with an additional one Be connected to the line. additionally could also the connections, switches and resistors be redundant. Both alternatives would An additional mean equipment expenditure.

Mit der Motorbremse nach der Erfindung wird insbesondere der Vorteil erzielt, dass ohne aufwändige Bauteile eine deutlich zuverlässigere und einfachere Bremse als bisher gegeben ist.With the engine brake according to the invention is particularly the advantage achieved that without consuming Components a much more reliable and easier brake than previously given.

Ein Ausführungsbeispiel der Motorbremse nach der Erfindung wird anhand der Zeichnung näher erläutert:
Einem Traktionsstromumrichter 1, der wenigstens einen Pulsstromumrichter aufweist, ist über Umschalter oder über erste Schalter 2a von Schalterkombinationen eine permanent erregte Synchronmaschine 3 nachgeschaltet. Es befindet sich jeweils einer von drei ersten Schaltern 2a in den drei Phasen der permanent erregten Synchronmaschine 3. Durch die Schalterkombinationen ist jede Phase der permanent erregten Synchronmaschine 3 entweder für den Fahrbetrieb über die ersten Schalter 2a mit dem Traktionsstromumrichter 1 verbunden oder für den Bremsbetrieb über zweite Schalter 2b der Schalterkombinationen mit Bremswiderständen 4.An embodiment of the engine brake according to the invention will be explained in more detail with reference to the drawing:
A traction current converter 1 which has at least one pulse-current converter is via change-over switches or via first switches 2a of switch combinations a permanently excited synchronous machine 3 downstream. It is each one of three first switches 2a in the three phases of the permanent magnet synchronous machine 3 , Due to the switch combinations, each phase of the permanently excited synchronous machine 3 either for driving over the first switches 2a with the traction power converter 1 connected or for braking operation via second switch 2 B the switch combinations with braking resistors 4 ,

Der erste der beiden Schalter 2a einer Schalterkombination befindet sich für jede Phase in der Verbindungsleitung vom Traktionsstromumrichter 1 zur permanent erregten Synchronmaschine 3. Der zweite der beiden Schalter 2b befindet sich in der Leitung, die an einem Abzweigungspunkt zwischen dem ersten Schalter 2a und der permanent erregten Synchronmaschine 3 von der Verbindungsleitung abzweigt und zu den Bremswiderständen 4 führt.The first of the two switches 2a a switch combination is located for each phase in the connection line of the Traktionsstromumrichter 1 to permanently excited synchronous machine 3 , The second of the two switches 2 B is located in the pipe at a junction point between the first switch 2a and the permanent-magnet synchronous machine 3 branches off from the connecting line and to the braking resistors 4 leads.

Die beiden Schalter 2a, 2b öffnen und schließen gegensinnig. Dadurch ist wie beim Umschalter die permanent erregte Synchronmaschine 3 entweder für den Fahrbetrieb mit dem Traktionsstromumrichter 1 oder für den Bremsbetrieb mit den Bremswiderständen 4 verbunden.The two switches 2a . 2 B open and close in opposite directions. As a result, as with the switch, the permanent-magnet synchronous machine 3 either for driving with the Traktionsstromumrichter 1 or for braking operation with the braking resistors 4 connected.

Während des Bremsvorganges wird durch den sich noch drehenden Läufer der permanent erregten Synchronmaschine 3 im Ständer ein Strom induziert, der über die Bremswiderstände 4 fließt und dadurch ein Bremsmoment im der permanent erregten Synchronmaschine 3 erzeugt.During the braking process is caused by the still rotating rotor of the permanent-magnet synchronous machine 3 in the stator induces a current through the braking resistors 4 flows and thereby a braking torque in the permanent magnet synchronous machine 3 generated.

Die Bremswiderstände 4 sind in einer als solchen bekannten Dreiecksschaltung angeordnet. Damit wird der Vorteil erzielt, dass jeder Bremswiderstand 4 über zwei Leitungen mit den zweiten Schaltern 2b der Schalterkombinationen und damit mit der permanent erregten Synchronmaschine 3 in Verbindung steht. Sollte eine Verbindung durch einen Defekt ausfallen, stehen dann noch zwei Drittel der Bremsleistung zur Verfügung, während bei einer Sternschaltung nur noch 50 % zur Verfügung stünden.The braking resistors 4 are arranged in a triangular circuit known as such. This gives the advantage that every braking resistor 4 over two lines with the second switches 2 B the switch combinations and thus with the permanent-magnet synchronous machine 3 communicates. If a connection fails due to a defect, then two-thirds of the braking power is still available, while with a star connection only 50% would be available.

Es wird der Vorteil erzielt, dass eine weniger störanfällige Motorbremse zur Verfügung gestellt wird.It the advantage is achieved that a less susceptible engine brake is provided.
