Description

Bei der selbsttätigen Streckenblockung mit Abhängigkeit zwischen zwei benachbarten Blockabschnitten ist es erwünscht, daß etwa auftretende Störungen in den Lampenstromkreisen (bei Durchbrennen der Lampen usw.) unter keinen Umständen einen Gefahrzustand herbeiführen. Sollte bei besetzter Blockstrecke die Haltlampe durchbrennen, so muß der Zug wenigstens durch das rückliegende HaItsignal geschützt werden.In the case of automatic route blocking with dependency between two neighboring ones Block sections, it is desirable that any faults that occur in the lamp circuits (if the lamps burn out, etc.) do not create a hazardous condition under any circumstances. Should be when the block section is occupied If the stop lamp burns out, then the train must at least through the stop signal behind it to be protected.

Es sind Schaltungen, z. B. aus dem Patent 495 347 > bekannt geworden, bei denen auch ohne Besetzung eines Abschnittes das Haltsignal erscheint, wenn die Stromzuführung über die Fahrschienen von dem am Ende befindlichen Speisetransformator unterbrochen wird. Dasselbe tritt auch ein, wenn der Primärkreis dieses Transformators (z. B. infolge Durchbrennens einer Sicherung) unterbrochen wird.There are circuits, e.g. B. from the patent 495 347> known, where also Without occupying a section the stop signal appears when the power supply is over the runways are interrupted by the feed transformer located at the end. The same thing also occurs if the primary circuit of this transformer (e.g. as a result of burnout a backup) is interrupted.

Erfindungsgemäß wird dieser Primärkreis dadurch unterbrochen, daß gemäß Abbildung die Signallampenströme des vorliegenden Abschnittes das Öffnen und Schließen dieses Primärstromkreises unmittelbar bewirken. Sämtliche Signalströme sind dabei über die Primärwicklungen 3, 4, 5, 6, 7, 8 eines Transformators E geführt, an dessen Sekundärwicklung 1, 2 der Heizfaden einer Gleichrichterröhre L1 angeschlossen ist.According to the invention, this primary circuit is interrupted in that, as shown in the figure, the signal lamp currents of the present section directly cause the opening and closing of this primary circuit. All signal currents are conducted via the primary windings 3, 4, 5, 6, 7, 8 of a transformer E , to whose secondary winding 1, 2 the filament of a rectifier tube L 1 is connected.

Im Primärstromkreis des Speisetransformators B liegt ein Sperrtransformator D, der sekundär auf den Anodenstromkreis der Gleichrichterröhre L1 geschaltet wird.In the primary circuit of the supply transformer B there is a flyback transformer D, which is connected secondarily to the anode circuit of the rectifier tube L 1 .

Hört die Heizung dieser Gleichrichterröhre durch Wegbleiben der Heizspannung am Transformatorli auf (etwa durch Unterbrechung einer der Signalstromkreise), so befindet sich der Sperrtransformator D im Sperrzustand, d. h. sein scheinbarer Widerstand steigt um ein Vielfaches. Hierbei ist der Primärstromkreis des Speisetransformators B praktisch geöffnet, so daß im zurückliegenden Blockabschnitt in bekannter Weise das Haltsignal erscheint.If the heating of this rectifier tube stops due to the heating voltage remaining at the Transformatorli (e.g. by interrupting one of the signal circuits), the blocking transformer D is in the blocking state, ie its apparent resistance increases many times over. In this case, the primary circuit of the supply transformer B is practically open, so that the stop signal appears in a known manner in the previous block section.
