Abstract

For an arrangement for charging the battery for the electrical system of a magnetic levitation vehicle which is supplied with the required charge voltage from linear generators and/or power rail current collector systems, and in which a supply of linear generator power is effected via bridge rectifiers and special charge devices, the circuit is to be simplified and the previous expenditure on contacts and charge devices is to be reduced. This is to be achieved in that alternating voltage is supplied via the power rail current collector system (5) using an additional bridge rectifier (6) with reactor (7) connected upstream for the purpose of limiting the current, and in that the additional bridge rectifier (6) is connected directly to the input of the charge device (3) provided for supplying linear generator power. Because of the use of the alternating current reactors, the output of the bridge rectifiers (6) is short-circuit-proof, which is comparable to the electrical characteristic line of the linear generator windings. Matching of the charge devices is no longer required. Even parallel supply of power is acceptable. <IMAGE>

Description

Die Erfindung bezieht sich auf eine Anordnung zum Laden der Bordnetzbatterie eines Magnetschwebefahrzeuges, wie sie im Oberbegriff des Anspruches näher definiert ist.The invention relates to an arrangement for loading the Vehicle battery of a magnetic levitation vehicle, as in the The preamble of the claim is defined in more detail.

Eine derartige Anordnung ist z.B. aus ZEV Glaser′s Annalen, 105 (1981), Nr. 7/8, Juli/August, S. 223, Bild 9, bekannt. Dort wird für Magnetschwebefahrzeuge eine Bordenergiever­ sorgung beschrieben mit einer Einspeisung über Lineargene­ ratoren und eine weitere unabhängige Einspeisung des Fahr­ zeuges über Stromschienen, die von Stromabnehmern kontak­ tiert werden. Die Lineargeneratoren ermöglichen dabei eine berührungsfreie Übertragung der an Bord erforderlichen Ener­ gie aus der Antriebsleistung des linearmotorgetriebenen Fahrzeuges. In die Wicklungen des Lineargenerators - die dort in den Polen der Tragmagnete angeordnet sind - werden bei Fahrbetrieb des Fahrzeuges Spannungen induziert. Der Lineargenerator als Spannungsquelle zeigt bei Belastung so­ genanntes Konstantstromverhalten, da mit Erhöhung der Ge­ schwindigkeit des Fahrzeuges nicht nur die in der Wicklung induzierte EMK, sondern auch die Frequenz ansteigt. Die ab­ gegebene Wechselspannung wird gleichgerichtet und man kann über spezielle Ladegeräte die Bordnetzbatterie des Fahr­ zeuges laden. Die bereits angeführte zusätzliche Strom­ schieneneinspeisung ist z.B. für stationären Betrieb an Haltepunkten gedacht, wenn der Lineargenerator keine Spannung mehr liefert. Die zweite Einspeisung erfolgt dabei über eine 750 V Gleichstromschiene. Zur stationären Ladung der Bord­ netzbatterle wird ein zusätzliches Ladegerät verwendet. Durch die voneinander unabhängigen Ladegeräte für die ver­ schiedenen Einspeisungen sind solche Anordnungen insbeson­ dere teuer und schwer.Such an arrangement is e.g. from ZEV Glaser’s annals, 105 (1981), No. 7/8, July / August, p. 223, picture 9. There is a board energy ver for magnetic levitation vehicles supply described with a feed via linear genes rators and another independent power supply for the driver Stuff about rails that contact pantographs be animals. The linear generators allow one non-contact transmission of the energy required on board gie from the drive power of the linear motor-driven Vehicle. In the windings of the linear generator - the there are arranged in the poles of the support magnets - be voltages induced during vehicle operation. The  Linear generator as a voltage source shows this under load called constant current behavior, since with increasing the Ge speed of the vehicle not only that in the winding induced EMF, but also the frequency increases. The off given AC voltage is rectified and you can the vehicle's on-board power supply battery via special chargers load stuff. The additional electricity already mentioned rail feed is e.g. for stationary operation Breakpoints thought when the linear generator had no voltage delivers more. The second feed takes place via a 750 V DC rail. For stationary loading of the board netzbatterle an additional charger is used. Thanks to the independent chargers for the ver different feeds are such arrangements in particular their expensive and heavy.

Es ist auch bereits vorgeschlagen worden, auch während des Fahrbetriebes die Speisung des Bordnetzes umschaltbar von Lineargenerator auf Stromschienen/Stromabnehmersystem oder umgekehrt durchzuführen. Dabei arbeitet die Einspeisung eines m-phasigen Lineargenerators und eine m-phasige Einspeisung über Stromabnehmer auf denselben Brückengleichrichter. Nach­ teilig bei diesem Vorschlag ist der hohe Aufwand an kontakt­ behafteten Schaltelementen in jeder der einzelnen Leitungen zum Brückengleichrichter.It has also been proposed, even during the Driving operation, the supply of the electrical system switchable from Linear generator on busbars / pantograph system or vice versa. The feed works here an m-phase linear generator and an m-phase feed via pantographs on the same bridge rectifier. After Part of this proposal is the high contact effort affected switching elements in each of the individual lines to the bridge rectifier.

Aufgabe der Erfindung ist es, eine Anordnung zum Laden der Bordnetzbatterie eines Magnetschwebefahrzeuges zu erstellen, die schaltungsmäßig einfacher ist und wesentliche Vorteile hinsichtlich des beanstandeten Kontakt- und Ladegerätauf­ wandes aufweist.The object of the invention is to provide an arrangement for loading To create the on-board electrical system battery of a magnetic levitation vehicle, which is simpler in terms of circuitry and significant advantages regarding the faulty contact and charger wall.

Die gestellte Aufgabe wird für eine Anordnung der eingangs genannten Art gemäß den kennzeichnenden Merkmalen des An­ spruchs gelöst. The task is for an arrangement of the beginning mentioned type in accordance with the characteristic features of the An solved.  

Anhand eines Ausführungsbeispieles wird die Erfindung im nachstehenden näher erläutert. Die Figur zeigt mehrere drei-phasige Lineargeneratoren 1, die zugeordnete Brücken­ gleichrichter 2 speisen. Auch höherphasige Lineargenera­ toren sind natürlich möglich. Über nachgeschaltete zuge­ ordnete Ladegeräte 3 (Gleichstromsteller) wird eine Bord­ netzbatterie 4 geladen. Bei Einspeisung über ein Strom­ schiene-Stromabnehmersystem 5 kann Wechselspannung (hier z.B. 380 V, 50 Hz) angelegt werden. Die Wechselspannung wird über einen zusätzlichen Brückengleichrichter 6 gleichge­ richtet. Vorgeschaltete Drosseln 7 dienen der Strombe­ grenzung. Die Gleichrichterausgänge sind direkt an die ent­ sprechenden Eingänge der für die Lineargeneratoreinspeisung vorgesehenen Ladegeräte 3 angeschlossen. Zweckmäßig ent­ spricht die Anzahl der Brückengleichrichter 6 denen der Brückengleichrichter 2. Durch die vorgeschalteten Drosseln 7 erhält auch Gleichrichter 6 als Spannungsquelle Konstant­ stromverhalten. Er entspricht damit Gleichrichter 2, der durch die elektrischen Kennlinien der Lineargeneratorwick­ lungen ebenfalls als Konstantstromquelle fungiert. Anstelle der Drossel kann auch ein strombegrenzender Transformator (Streufeldtrafo) eingesetzt werden. Die er­ findungsgemäße Schaltung hat folgende Vorteile:The invention is explained in more detail below using an exemplary embodiment. The figure shows a plurality of three-phase linear generators 1 , which feed the associated bridge rectifier 2 . High-phase linear generators are of course also possible. An on-board power battery 4 is charged via downstream assigned chargers 3 (DC controllers). When feeding via a power rail pantograph system 5 , alternating voltage (here, for example, 380 V, 50 Hz) can be applied. The AC voltage is rectified via an additional bridge rectifier 6 . Upstream chokes 7 serve to limit the current. The rectifier outputs are connected directly to the corresponding inputs of the chargers 3 provided for the linear generator feed. Appropriately, the number of bridge rectifiers 6 corresponds to those of the bridge rectifiers 2 . The upstream chokes 7 also give rectifier 6 constant current behavior as a voltage source. It thus corresponds to rectifier 2 , which also functions as a constant current source due to the electrical characteristics of the linear generator windings. Instead of the choke, a current-limiting transformer (stray field transformer) can also be used. The circuit according to the invention has the following advantages:

Zur Batterieladung bei Stillstand und bei Fahrbetrieb wird das gleiche Gerät 3 benutzt.The same device 3 is used to charge the battery when the vehicle is at a standstill and when driving.

Wegen des Einsatzes der Wechselstromdrosseln 6 ist der Aus­ gang der Brückengleichrichter 6 kurzschlußfest, was der elektrischen Kennlinie der Lineargeneratorwicklungen ver­ gleichbar ist.Due to the use of the AC reactors 6 is off transition of the bridge rectifier 6 short-circuit proof that the electrical characteristics of the linear generator windings is comparable.

Bei Einspeisung aus Lineargeneratoren 1 oder aus Strom­ schienen-Stromabnehmersystemen 5 ist keine Anpassung der Funktion der Ladegeräte 3 mehr erforderlich. Sogar Parallel­ einspeisung ist zulässig, da es infolge des Konstantstrom­ verhaltens der verschiedenen Gleichrichterbrücken 2 und 6 nicht mehr auf unbedingte Spannungsgleichheit ankommt.When feeding from linear generators 1 or from current rail pantograph systems 5, it is no longer necessary to adapt the function of the chargers 3 . Even parallel feed-in is permissible because the constant current behavior of the different rectifier bridges 2 and 6 means that it is no longer essential to have the same voltage.

Kontaktbehaftete Schaltelemente 8 und 9 sind lediglich in den Hochstromkreisen erforderlich, nicht aber zur Umschal­ tung der Einspeisungen.Contact-based switching elements 8 and 9 are only required in the high-current circuits, but not for switching the feeds.

Sicherungen 10 sind nur als Leitungsschutz, nicht aber zum internen Schutz einzelner Geräte erforderlich.Fuses 10 are only required as line protection, but not for the internal protection of individual devices.
