Description
Die im Patent 551 261 beschriebene Überwachung elektrisch gestellter Weichen geschieht durch sekundäre Reihenschaltung verschiedener Überwachungstransformatoren 9, während ihre Primärwicklung vom Überwachungsstrom am Antrieb durchflossen wird. Der Signalsperrmagnet erhält dabei verschieden hohe Spannung je nach Anzahl der zur Fahrstraße gehörigen Weichen. EsThe monitoring described in patent 551,261 Electrically set points are made by connecting different secondary switches in series Monitoring transformers 9, while their primary winding from the monitoring current is flowed through at the drive. The signal blocking magnet receives different voltages depending on the number of the turnouts belonging to the route. It
jo ist dabei notwendig, seine Wicklung entweder mit Anzapfungen zu versehen oder die überschüssige Magnetisierungsleistung durch Vorschaltwiderstände zu vernichten. Andererseits hat diese Schaltung den Nachteil, daß besonders bei einer größeren Anzahl in Reihe geschalteter Überwachungstransformatoren durch Ausfallen eines oder mehrerer derselben — z. B. durch Liegenbleiben der zugehörigen Antriebe beim Hebelumlegen —jo is necessary either to provide his winding with taps or the excess Destroy magnetizing power through series resistors. On the other hand, this circuit has the disadvantage that especially with a large number of monitoring transformers connected in series by failure of one or more of the same - z. B. by lying where the associated drives when moving the lever -
ao die Drosselspannung zu groß wird. Der induktive Widerstand kann, wenn man durch entsprechende Bemessung nicht unverhältnismäßig große Überwachungstransformatoren in Kauf nehmen will, im Verhältnis zu dem des Sperrmagneten zu klein werden, wodurch dieser in der Lage ist, seinen Anker vorschriftswidrig anzuziehen.ao the choke voltage is too high. The inductive resistance can if you go through appropriate rating not disproportionately large monitoring transformers wants to accept to be too small in relation to that of the locking magnet, whereby he is able to tighten his anchor contrary to the regulations.
Dieser Nachteil wird erfindungsgemäß dadurch vermieden, daß die in Reihe geschalteten Überwachungstransformatoren 9' bis gx nicht unmittelbar, sondern über einen besonderen mit konstanter Spannung gespeisten Gegentransformator GT an den Sperrmagneten M gelegt werden. Die Anzapfung a des Gegentransformators richtet sich nach der jeweiligen Anzahl der Transformatoren 9', 9" usw., so daß der Sperrmagnet M immer dieselbe Spannung erhält und so mit konstanter Zugkraft arbeitet. Die Spannung an der Anzapfung α liegt jeweils um einen gewissen Betrag unter der Summe aller Einzelspannungen der Überwachungstransformatoren. Fallen nun ein oder mehrere Überwachungstransformatoren bei geschlossenen Fahrstraßenkontakten 6" aus, so vermindert sich die für den Sperrmagneten maßgebende Restspannung in erheblichem Maß. Dieser kann dabei seinen Anker nicht anziehen und den Signalhebel entSperren.According to the invention, this disadvantage is avoided in that the series-connected monitoring transformers 9 'to g x are not connected to the blocking magnet M directly, but rather via a special counter-transformer GT fed with a constant voltage. The tap a of the counter-transformer depends on the respective number of transformers 9 ', 9 ", etc., so that the blocking magnet M always receives the same voltage and thus works with constant tensile force. The voltage at the tap α is below a certain amount the sum of all individual voltages of the monitoring transformers. If one or more monitoring transformers fail when the route contacts 6 ″ are closed, the residual voltage that is decisive for the blocking magnet is reduced to a considerable extent. This cannot tighten its armature and unlock the signal lever.
