Die Zeichnung zeigt zwei Ausführungsbeispiele für verschiedene Stromkreisverbindungen zweier durch Wechselstrom gespeister Signallampen. The drawing shows two exemplary embodiments for different circuit connections two signal lamps fed by alternating current.

Bei der Ausführungsform nach Fig. 1 ist eine Signallampe 1 vorgesehen, die als HaItsignal rotes Licht zeigt, während eine Lampe 2 grünes Licht aussenden soll. Die Lampen 1 und 2 werden mit Strom von der Sekundärwicklung 3 eines Hilfstransformators 4 gespeist, dessen Primärwicklung 5 mit einer geeigneten Wechselstromquelle verbunden ist. Die rote Signallampe 1 ist an geeigneter Stelle an die Transformatorwicklung 3 angeschlossen und in Reihe mit der Sekundärwicklung 6 eines Transformators 7 geschaltet, der die Uberwachungsvorrichtung darstellt. Die Primärwicklung 8 des Transformators 7 ist in Reihe mit der grünen Signallampe 2 geschaltet und mit den Klemmen der Sekundärwicklung 3 des Transformators 4 verbunden, wobei in dieser Leitung auch die Kontakte 9 eines Relais 10 liegen, das von einem Gleissignalstromkreis 11 in der üblichen Weise erregt wird.In the embodiment according to FIG. 1, a signal lamp 1 is provided which acts as a hold signal shows red light, while a lamp 2 should emit green light. The lamps 1 and 2 are fed with current from the secondary winding 3 of an auxiliary transformer 4, whose primary winding 5 is connected to a suitable alternating current source. The Red Signal lamp 1 is connected to the transformer winding 3 at a suitable point and is in Series connected to the secondary winding 6 of a transformer 7, which is the monitoring device represents. The primary winding 8 of the transformer 7 is in series with the green signal lamp 2 and connected to the terminals of the secondary winding 3 of the transformer 4 connected, the contacts 9 of a relay 10 also being in this line, which is excited by a track signal circuit 11 in the usual way.

Die Wirkungsweise der Einrichtung ist folgende: The device works as follows:

Wenn der Streckenabschnitt des Gleises, zu dem die Signallampen 1 und 2 gehören, nicht durch ein Fahrzeug oder einen: Zug besetzt ist, so erregt der Signalstrom, der den Gleichstromkreis it durchläuft, das Relais 10 und hält dadurch die Schaltkontakte 9 geschlossen, während das Vorhandensein eines Zuges oder eines Fahrzeuges in dem Streckenabschnitt das Relais 10 stromlos macht und die Kontakte 9 öffnet. In diesem Falle erhält die rote Signallampe 1 Strom von dem Teile der Sekundärwicklung 3 des Hilfstransformators 4, mit dem sie verbunden ist, während der Stromkreis über die Primärwicklung 8 der Vorrichtung 7 an den Relaiskontakten 9 unterbrochen ist. Der von der Sekundärwicklung 3 ausgehende Strom bewirkt 'daher, daß die Lampe 1 aufleuchtet und das Haltsignal gibt. Sobald indessen der Zug oder das Fahrzeug den Streckenabschnitt verlassen hat,_; wird das Relais erregt, so daß es den Stromkreis für die grüne Signallampe 2 und die Primärwicklung 8 des Transformators 7 schließt. Dieser Transformator ist so bemessen, daß dabei die elektromotorische Kraft, die in der Sekundärwicklung 6 von dem die Primärwicklung 8 durchfließenden Strom induziert wird, gleich und entgegengesetzt der elektromotorischen Kraft zwischen den Punkten der Sekundärwicklung 3 des Hilfstransformators 4 ist, an die der Stromkreis für die rote Signallampe 1If the section of the track to which the signal lamps 1 and 2 belong is not occupied by a vehicle or a train, the signal current that runs through the DC circuit it excites the relay 10 and thereby keeps the switching contacts 9 closed while the The presence of a train or a vehicle in the route section de-energizes the relay 10 and opens the contacts 9. In this case, the red signal lamp 1 receives current from the part of the secondary winding 3 of the auxiliary transformer 4 to which it is connected, while the circuit via the primary winding 8 of the device 7 at the relay contacts 9 is interrupted. The current emanating from the secondary winding 3 therefore causes the lamp 1 to light up and give the stop signal. Once, however, the train or the vehicle has left the track _section; the relay is energized so that it closes the circuit for the green signal lamp 2 and the primary winding 8 of the transformer 7. This transformer is dimensioned so that the electromotive force induced in the secondary winding 6 by the current flowing through the primary winding 8 is equal and opposite to the electromotive force between the points of the secondary winding 3 of the auxiliary transformer 4 to which the circuit for the red signal lamp 1

Claims

connected. Two equal and opposite electromotive forces therefore act on this circuit, namely one from the transformer 4 and another from the transformer 7, so that no current flows through the secondary winding 6 and the red signal lamp 1 therefore remains dark; the green signal lamp 2, on the other hand, receives power from its own electrical circuit and therefore lights up and gives a corresponding signal. In the embodiment of Fig. 2, the red signal lamp 1 is connected in parallel to the secondary winding 6 of the transformer 7 between suitable points of the secondary winding 3 of the auxiliary transformer 4, while the green signal lamp 2 is connected in series with the primary winding 8 of the transformer 7, as in the in Fig. 1 shown arrangement. The mode of operation of this embodiment of the invention is as follows: As long as the relay 10 is de-energized, the circuit of the green signal lamp 2 remains open, and the current flows from the auxiliary transformer 4 via the red signal lamp 1 and through the primary winding 6 of the transformer 7, which are parallel to each other are switched ·. As a result of the high induction resistance of the winding 6, however, the greater part of the current flows through the red signal lamp 1, which consequently lights up and gives the danger signal. When the relay 10 is energized and closes the circuit for the green signal lamp 2, the current which flows through the lamp and the primary winding 8 of the transformer 7 generates an induction current of such strength and phase in the magnetic circuit of the transformer 7 that the existing impedance of the secondary winding 6 is neutralized; as a result, the current flows; which runs through the circuit of the red signal lamp ι, almost entirely through the winding 6 of the transformer 7, so that in this way the red signal lamp 1 is short-circuited and therefore does not light up, while the green signal lamp 2. of which the current flowing through the primary winding 8 is made to glow and causes a corresponding signal display. If necessary, a resistor 12 can be switched into the circuit of the red signal lamp 1 in order to limit the current intensity when the lamp 1 is short-circuited by the induction effect of the transformer 7. In the description, two signal lamps are assumed that emit red and green light; however, the invention is not limited to the use of two lamps of the specified colors, but can also be used to operate two or more groups of lamps or other display devices which can give any desired signal. The monitoring device 7, which in the alternating current system described is formed by an induction device or a transformer, can of course also be provided by a shunt ο. Like. Be replaced in cases where the invention is to be used for continuous currents or direct current, the shunt then serving to divert the current from the one signal lamp or display device when a circuit monitored by the track signal current is closed or opened *.
