Description

Schaltungsanordnung für die Stromversorgung von mit Wechselstrom betriebenen Gleisstromkreisen Die Erfindung bezieht sich auf Gleisstromkreise in Bahnanlagen, deren Schienen von Wechseltriebstrom .durchflossen werden. In solchen Anlagen werden vielfach Motorrelais mixt einer Hilfs- und einer Gleiswicklung verwendet. Die Hilfswicklung ist ständig an das Netz angesichlossen, während die Gloiswickl-ung inbekannter r Weisei über 'dieLSchienen des betreffenden Gleisstromkreises gespeist wird. Um bei Wechselistrombahnen eine F'remdbeeinflussung der Blockrelais zu verhindern, hat man vorgeschlagen, den Blockstrom mehrmals innerhalb einer Zeiteinheit umzupolen. Voraussetzung für den Anzug der Rella:is ist dabei, daß der in der Gleisphase fließende Strom im gleichen Takt und zur gleichen Zeit wie der Strom in der Hilfshase unter Berücksichtigung der notwendigen Phasenlage umgepolt wird. Werden jedoch die beiden Schienen des Gleisstromkreises durch Zugachsen kurzgeschlossen und kommt nun in die Gleisphase eine durch den Triebstrom transformierte F'remdspannung, so kann diese das Relais nicht zum Anziehen bringen, da die Voraussetzungen für den Anzug des Relais infolge dauernder Umpolung der Hilfsphase nicht vorhanden sind.Circuit arrangement for the power supply of alternating current operated Track circuits The invention relates to track circuits in railway systems, the rails of which have alternating drive current. In such plants will be often used motor relay mixes an auxiliary and a track winding. The auxiliary winding is constantly connected to the network, while the Gloiswickl-ung in known r Weisei is fed via the rails of the relevant track circuit. To at To prevent alternating current railways an external influence on the block relays it was proposed to reverse the polarity of the block current several times within a unit of time. The prerequisite for the suit of the Rella: is that the flowing in the track phase Current in the same cycle and at the same time as the current in the auxiliary bunny below The polarity is reversed, taking into account the necessary phase position. However, the two will Rails of the track circuit short-circuited by train axles and now comes in the track phase an external voltage transformed by the drive current, so can this does not cause the relay to pick up, as the requirements for pick-up of the relay are not available due to constant polarity reversal of the auxiliary phase.

Die Erfindung soll nach weitergehen, die Sicherhei=t gegen Fremdbeeinflussung erhöheni, und erreicht dies dadurch, ddaß die Änderung der Phasenlage innerhalb einer Zeiteinheit in voneinander verschiedenen Abständen erfolgt. Man schließt hierdurch eine Beeinflussung durch störende Oberwellen. vollkommen aus,, da der Fall praktisch kaum auftreten kann" da,ß die Interferenzfrequenz aus Blockstrom und der störenden Oberwelle des Triebs,tromes die gleiche unregelmäßige We@chsseilgeschwindUgkei-t hat wie der Takt der Umpolung und d@aß hierbei, außerdem der bei der Interferenz auftretende Wechsel in der Drehrichtung des Motorrelais mit dem Umpolvargang zeitlich zusammenfällt. Zur Erläuterung solcher Vorgänge sei einmal angenommen, die Blockfrequenz würde 5o Hz betragen.. Eine Störfrequenz für der GleiswickIung des Relaiss in der Größe von 45 Hz würde zusammen mit dem Blockstrom der Hilfswicklung von 5o Hz bewirken, da,ß bei den entsprechenden Voraussetzungen, wie günstige Phasenlage, Größe der Amplitude u@sw., dass Relais in der Sekunde zehnreal die Richtung seines Anzugsmomentes ändern würde. Würde nun die Blockfrequenz von 5o Hz entsprechend dem vorhergesagten zehnmal in der Sekunde umgepolt und zeitlich die Umpolung im selben Augenblick erfolgen wie der Wechsel in der Richtung des Drehmoni@entes, der durch die Interferenz hervorgerufen wird, so würde die Wirkung der beschriebenen Interferenz,frequenz audgehoben, weil jedesmal, wenn durch die verschiedenen Frequenzen in Gleie@ und: Hilfsphase sich die Phasenlage ändern würde, dann durch die Umpolung diese Änderung der Phasenlage wieder aufgehoben wäre und in denn: Relais ein Drehmoment derselben Richtung zustande kommen und der Anker anziehen könnte. Hierdurch wäre das Auftreten einest Gefahrenzustandes möglich. Wie bereits vorgeschlagen würde, kann man auch den vorbeschriebenen Zustand durch stetiges Ändern: der Phasenlage vermeiden. Einfacher wird dies durch die Erfindung erreicht, wobei man die Änderungen der Phrasenlage in voneinander verschiedenen Abständen innerhalb einer Zeiteinheit vornimmt.The invention is intended to continue, the security against external influences increasei, and achieves this by the fact that the change in phase position within a unit of time in each other takes place at different intervals. This means that there is no influence from interfering harmonics. completely from "because the case can hardly occur in practice" there, ß the interference frequency Block current and the disturbing harmonic of the drive, tromes the same irregular We @ chsseilgeschwindUgkei-t has like the cycle of polarity reversal and d @ ate here, also the change in the direction of rotation of the motor relay that occurs during interference coincides in time with the polarity reversal. To explain such processes let once suppose the block frequency would be 50 Hz. An interfering frequency for the track winding of the relay in the size of 45 Hz would be combined with the block current of the auxiliary winding of 5o Hz cause, ß with the appropriate conditions, such as favorable phase position, size of the amplitude u @ sw. that relay in the second ten real would change the direction of its tightening torque. Would the block frequency of 50 Hz corresponding to the predicted ten times a second reversed polarity and time the polarity reversal takes place at the same time as the change in the direction of the rotary counter, caused by the interference, the effect would be as described Interference, frequency highlighted because every time through the different frequencies in equations @ and: auxiliary phase the phase position would change, then by reversing the polarity this change in the phase position would be canceled again and then: relay a torque in the same direction and the anchor could attract. This would be the occurrence of a dangerous state is possible. As already suggested, you can also change the previously described state by constantly changing: the phase position avoid. Easier this is achieved by the invention, taking into account the changes the phrase position at different intervals within a unit of time undertakes.
