Description
Bei Relais im Eisenbahnsicherrungswesen tritt häufig ,die Notwendigkeit auf, die Arbeitsgeschwindigkeit derselben wesentlich zu verkleinern. In vielen Fällen ist es auch wünschenswert, dieselbe innerhalb gewisser Grenzen ändern zu können.The need often occurs with relays in railway safety systems to reduce the operating speed of the same significantly. In many cases it is also desirable to be able to change the same within certain limits.
Handelt es sich,um Dreilagenmotorrelais, so ist die Rückwärtsbewegung in die Mittellage (Ruhelage) in allen Fällen so zu verlangsamen" daß der Rotor in der Mittellage ,zum. .Stehen kommt bzw. nur einen unbedeutenden Ausschlag nach der anderen Seite macht. Man vermeidet dadurch, -daß die Kontakte der anderen Seite, wenn auch nur kurzzeitig, geschlossen werden, Ebenso wird das unangenehme Pendeln des Rotors um die Mittellage, welches nicht notwendigerweise zu einem Schluß der :gegenüberliegenden Kontakte führen muß, aber einen Schönheitsfehler darstellt, vermieden.If it is a three-position motor relay, then it is the backward movement in the central position (rest position) to slow down in all cases so that the rotor in the central position, for. . Standing comes or only an insignificant rash after the other side makes. This avoids -that the contacts on the other side, even if only for a short time, will be closed, so will the uncomfortable commuting of the rotor around the central position, which does not necessarily lead to a conclusion of the : must lead opposite contacts, but is a blemish, avoided.
Es ist an sich bekannt, die Ankerbewegung bei induktionst- und Motorrelais für Eisenbahnsicherunrgseinrichtungen durch eine mit dem Anker geku.,ppelte Wirbelsbrombremse zu verlangsamen. Es is-b ferner bekannt, einen Wechselstrommotor nach Abschaltung des Wechsel's-tromes dadurch abzubremsen, .daß man in die Wicklung des Motors Gleichstrom einführt. Die Erfindung bezweckt in ähnlicher Weise eine zweckentsprechende Abbremsung des Ankers bei Induktions- oder Motorrelais :zu erzielen, was dadurch geschieht, daß das Gleichfeld durch Einschalten einer Sperrzelle zweckmäßig mit parallel geschaltetem Ohmschen Widerstand in eine Wicklumgszu'leitung zum Relais erzeugt wird:.It is known per se, the armature movement in induction and motor relays for railway safety devices by means of a vortex brake that is kissed with the anchor to slow down. It is also known to use an AC motor after it has been switched off of the alternating current by braking. That one direct current into the winding of the motor introduces. The invention aims in a similar way to an appropriate deceleration of the armature in induction or motor relays: to achieve what it does, that the constant field by switching on a blocking cell expediently connected in parallel Ohmic resistance is generated in a winding feed line to the relay :.
Die Erfindung ist in der Zeichnung -beispielsweise erläutert.The invention is illustrated in the drawing, for example.
Hierbei ist der Anker eines Motorrelais in an gezogener Lage dargestellt, wobei die eine Wicklung in 'bekannter Weise an Idas: Gleis angeschlossen ist und eine zweite Wicklung 26 unmittelbar an der Wechselstromquelle liegt. In Reihe mit der Hil'Fs-,phasenwickl,ung 26 liegt eine Sperrzelle: 17. Hierbei ist das 'Drehfeld im Relais noch genügend groß, um. das erforderliche iDrehmoment zum Stellen des Relais aufzubringen, anderseits ist der Anteil an Gleichstrom. auch ausreichend, um eine genügend große Bremskraft = erzeugen.Here, the armature of a motor relay is shown in the pulled position, one winding being connected to the track in a known manner and a second winding 26 being connected directly to the alternating current source. In series with the auxiliary phase winding 26 there is a blocking cell: 1 7. Here, the rotating field in the relay is still large enough to. to apply the required torque to set the relay, on the other hand is the proportion of direct current. also sufficient to generate a sufficiently large braking force =.
Es hat sich ferner gezeigt, daß man mit Hilfe eines der Sperrzelle parallel liegenden regelbaren Widerstandes 18 .die Bremswirkung in genügendem. Maßte regeln: kann.It has also been shown that you can use one of the lock cell parallel adjustable resistor 18 .the braking effect in sufficient. Measured regulate: can.
Es ist auch möglich, die Sperrzelle parallel zur Wicklung 26 zu legen, wobei ein gemeinsamer Vorwiderstand nötig ist.It is also possible to place the blocking cell parallel to winding 26, whereby a common series resistor is required.
Will man .die Bremsung erst dann eintreten lassen, wenn,der Stift 13 stich kurz vor der Mittellage befindet, so 'kann man parallel zäum Widerstand 18 einen Kontakt, 30 vorsehen, der durch den Anker betätigt wird, kurz vor Erreichen der Mittellage des ,Stiftes 13 den Kurzschluß unterbricht und in der Mittellage selbst wieder schließt.If you want to let the braking only occur when the pin 13 is stabbed shortly before the central position, you can provide a contact 30 parallel to the resistor 1 8 , which is actuated by the armature shortly before the central position of the , Pin 13 interrupts the short circuit and closes again in the central position itself.
