Description
<Desc/Clms Page number 1>
Einrichtung zum Schutz von Quecksilberdampfgleichrichtern und ähnlichen Apparaten.
EMI1.1
<Desc/Clms Page number 2>
EMI2.1
auf einen niedrigeren Strom anspricht als das Relais 6. Beim Ansprechen des Relais 6 oder 6 auf einen unzulässigen Überstrom wird über den Kontakt 7 bzw. 8 der über die Batterie 9 verlaufende Stromkreis für die Auslösespule 10 geschlossen.
Bei dem Ausführungsbeispiel nach Fig. 2 ist nur ein Überstromrelais 6 vorgesehen, dem bei hoher Temperatur des Gleichrichtergefässes über die linke Stellung des Bimetallstreifens 2 ein Widerstand 12 vorgeschaltet ist, so dass das Relais erst bei einem höheren Strom anspricht als bei niedrigerer Temperatur des Gleichriehtergefässes, wobei der Bimetallstreifen die gezeichnete Lage einnimmt und das Relais 5 unmittelbar mit dem Transformator verbindet.
Der Thermoschalter ist zweckmässig in bekannter Weise so ausgebildet, dass er sich unter Schnappwirkung von der einen Stellung in die andere bewegt.
PATENT-ANSPRÜCHE :
1. Einrichtung zum Schutz von dampfgefüllten Entladungsröhren, insbesondere Quecksilberdampfgleichrichtern, dadurch gekennzeichnet, dass eine von der Temperatur des Entladungsgefässes und vom Belastungsstrom abhängige Überlastungsschutzvorriehtung vorgesehen ist.

EMI2.1
responds to a lower current than the relay 6. When the relay 6 or 6 responds to an impermissible overcurrent, the circuit for the trip coil 10 via the contact 7 or 8 is closed.
In the embodiment according to FIG. 2, only one overcurrent relay 6 is provided, which is preceded by a resistor 12 via the left position of the bimetal strip 2 at a high temperature of the rectifier vessel, so that the relay only responds at a higher current than at a lower temperature of the rectifier vessel, wherein the bimetallic strip assumes the position shown and connects the relay 5 directly to the transformer.
The thermal switch is expediently designed in a known manner so that it moves from one position to the other with a snap action.
PATENT CLAIMS:
1. Device for protecting vapor-filled discharge tubes, in particular mercury vapor rectifiers, characterized in that an overload protection device is provided which is dependent on the temperature of the discharge vessel and the load current.
