Einrichtung zur Verhinderung des Überfahrens eines Haltsignals bei elektrisch angetriebenen Fahrzeugen.Device for preventing the crossing of a stop signal in electrically powered vehicles.
Die Erfindung betrifft eine Einrichtung zur Verhinderung des Überfahrens eines Haltsignals bei elektrisch angetriebenen Fahrzeugen. Es ist in bekannter Weise eine Hilfsschiene verwendet, die der Stromschiene gegenüberliegt und durch den Signalflügel unter Spannung gesetzt wird. Die Erfindung besteht darin, daß der Hilfsschiene eine "Wechselstromspannung zugeführt wird. Hierdurch wird der Vorteil erzielt, daß beispiels-The invention relates to a device for preventing a stop signal from being exceeded in electrically powered vehicles. It is an auxiliary rail in a known manner used, which is opposite the busbar and through the signal wing is put under tension. The invention consists in that the auxiliary rail a "AC voltage is supplied. This has the advantage that, for example,

Die Abbildung zeigt schematisch ein Ausführungsbeispiel. The figure shows schematically an embodiment.
α ist ein Fahrzeug mit den Stromabnehmern
b, c. d ist die Stromschiene, e die Hilfsschiene, die mit einem Pol einer Wechselstromquelle/
verbunden ist. Von deren fueier Klemme führt eine Leitung zu dem vom Signal g gesteuerten Schalter ft, dessen
freie Klemme wiederum durch eine Leitung mit der Stromschiene d verbunden ist. Auf
dem Fahrzeug sind die 'Stromabnehmer b und c über Transformatorenwicklungen k, tti
mit der über den Fahrschalter zu den Motoren führenden Leitungen η verbunden. Zu
den Transformatorwicklungen k, tn gehören die Wicklungen o, p, deren Klemmen mit
denen des Relais q verbunden sind.
Die Wirkungsweise ist folgende:
Steht das Signal g auf »Halt«, so ist der Schalter h geschlossen. Gelangt ein Fahrzeug
in die gezeichnete Stellung, so fließt ein Strom aus der Wechselstromquelle/ über Schalterh,
Stromschiene d, Stromabnehmer b, Transformatorwicklungen k, m, Stromabnehmer c,
Hilfsschiene e zair Wechselstromquielle / zurück.
Der die Wicklungen k und ttt durchfließende
Strom induziert in den Wicklungen Ό, ρ Ströme, die infolge entsprechender
Schaltung sich addieren und gemeinsam das Relais q zum Ansprechen bringen. Dieses
kann dann in irgendeiner bekannten Weise den Fahrzeugstrom unterbrechen und die Bremse usw. anstellen. α is a vehicle with pantographs b, c. d is the busbar, e is the auxiliary bar, which is connected to one pole of an alternating current source /. A line leads from its four terminal to the switch ft controlled by the signal g , the free terminal of which is in turn connected by a line to the busbar d . On the vehicle, the pantographs b and c are connected via transformer windings k, tti to the lines η leading to the motors via the drive switch. The transformer windings k, tn include the windings o, p, the terminals of which are connected to those of the relay q.
The mode of action is as follows:
If the signal g is on "Halt", the switch h is closed. When a vehicle arrives in the position shown, a current flows from the alternating current source / via switch h, busbar d, current collector b, transformer windings k, m, current collector c, auxiliary rail e zair alternating current source / back. The current flowing through the windings k and ttt induces currents in the windings Ό, ρ , which add up as a result of corresponding switching and together make the relay q respond. This can then interrupt the vehicle power and apply the brake, etc. in any known manner.
Beim Fahrbetrieb wird eine der Wicklungen k oder m auch von dem Antriebsstrom des Fahrzeuges durchflossen, und beim Einschalten kann ein kurzer Stromstoß in der zugehörigen Wicklung ο oder ρ induziert werden. Es bereitet jedoch, keine Schwierigkeiten, das Relais q so zu bauen, daß es hierauf nicht anspricht.When driving, one of the windings k or m is also traversed by the drive current of the vehicle, and when it is switched on, a short current surge can be induced in the associated winding ο or ρ. However, there is no difficulty in building the relay q in such a way that it does not respond to it.
