Description

Translated fromGerman

  Anordnung zur     Widerstands-Bremsung    von mit     Wechselstrom-Kollektormotoren     betriebenen Fahrzeugen.    Es ist bekannt, bei     Wechselstrombahnen,     die mit     Kollektormotoren    betrieben werden,  die Fahrzeuge dadurch elektrisch zu bremsen,  dass man die Motoren vom Netze abschaltet  und als Gleichstromdynamos auf     Widerstände     arbeiten lässt, in denen die Bremsenergie in  Wärme umgesetzt wird. Beim Bremsen hat  man die Motoren sowohl mit Selbsterregung,  als auch mit Fremderregung betrieben.    Nach der Erfindung handelt es sich um  eine Anordnung letzterer Art, bei der die  Erregerwicklung des Motors beim Brems  betriebe Strom von einer besonderen Gleich  strommaschine erhält.   Erfindungsgemäss wird  diese Erregermaschine von dem ohnehin vor  handenen     Licht-Motorgenerator    angetrieben,  und zwar beim Ausbleiben des Netzstromes  derart, dass die Lichtdynamo als Motor von  der mit ihr parallelgeschalteten Sammler  batterie gespeist wird.    Eine     .erartige    Anlage ist in der Zeich  nung     schematisch    dargestellt. Darin bedeutet  den Triebmotor, der in Fahrbetrieb an den  Haupttransformator b angeschlossen ist,     ini       Bremsbetriebe jedoch auf den Widerstand     c     arbeitet.   Dabei wird seine     Erregerwicklung        d     von der     Gleichstrommaschine        e    gespeist, die  mit dem Lichtumformer f, g gekuppelt ist.  Wird die Oberleitung h. stromlos oder der  Stromabnehmer i heruntergeklappt (gestri  chelte Lage), so verliert der     Wec.hselstrom-          motor        g    sein Drehmoment     u::d    die     (fleich-          stroin-Liclitdyiamo    f läuft, gespeist von der  Batterie /r, als     Motor    und treibt die Erreger  maschine e an.    Durch die Schaltung wird bewirkt,     dah     trotz Versagen oder     Zerstörung    der übrigen  Bremseinrichtungen der elektrischen Loko  motive diese selbst dann noch gebremst wer  den kann,     wenn    der Netzstrom ausbleibt oder  die Stromabnehmer heruntergeklappt oder  ebenfalls zerstört sind.  Arrangement for resistance braking of vehicles operated with alternating current collector motors. It is known to brake the vehicles electrically in AC railways operated with collector motors by disconnecting the motors from the mains and allowing them to work as DC dynamos on resistors in which the braking energy is converted into heat. When braking, the motors were operated with both self-excitation and external excitation. According to the invention, there is an arrangement of the latter type, in which the excitation winding of the motor during braking operations receives electricity from a special DC machine.   According to the invention, this exciter is driven by the already existing light motor generator, and when the mains power fails, in such a way that the light dynamo is powered as a motor by the collector battery connected in parallel with it. Such a system is shown schematically in the drawing. It means the traction motor, which is connected to the main transformer b while driving, but works on the resistor c in braking operations.   Its excitation winding d is fed by the direct current machine e, which is coupled to the light converter f, g. If the overhead line h. de-energized or the pantograph i folded down (dashed line), the alternating current motor g loses its torque u :: d which runs, powered by the battery, as a motor and drives the exciters machine e on.  The circuit has the effect that, despite the failure or destruction of the other braking devices of the electric locomotive, these motives are still braked if the mains power fails or the pantographs are folded down or also destroyed.
