Description

Relais Feste elektrolytische Leiter, insbesondere Salze, besitzen bekanntlich einen sehr hohen Temperaturkoeffizienten der Leitfähigkeit, besonders im Temperaturgebiet nahe am Schmelzpunkt.Relays have solid electrolytic conductors, especially salts known to have a very high temperature coefficient of conductivity, especially in the temperature range close to the melting point.

Erfindungsgemäß kann diese Eigenschaft zum Schließen und öffnen eines Stromkreises ausgenutzt werden. Die beigegebene Figur diene zur Erläuterung. A ist ein geschlossenes Metallröhrchen, in welches ein Metallstab B isolierend (D) eingeführt ist und im übrigen mit dem Salz nahezu gefüllt ist. A und B sind mit Anschlüssen zur Verbindung mit dem Hauptstromkreis V1 ausgestattet. C ist ein Heizwiderstand, der in gutem Wärinkontakt mit dem vorbeschriebenen Teil steht, der elektrisch isoliert ist und in den Kreis V. eingeschaltet ist.According to the invention, this property can be used to close and open a circuit. The attached figure is used for explanation. A is a closed metal tube into which a metal rod B is inserted in an insulating manner (D) and is almost completely filled with the salt. A and B are equipped with connectors for connection to the main circuit V1. C is a heating resistor which is in good thermal contact with the part described above, which is electrically insulated and connected to circuit V.

Bei der Raumtemperatur ist das Salz fest und praktisch isolierend, der Kreis V, also offen. Fließt nun durch V2 ein Strom, so wird A erwärmt, das Salz wird zum Leiter und der Kreis V1 geschlossen, wobei der Strom selbst zur Erwärmung und damit zur Verbesserung der Leitung des Salzes beiträgt. Die Vorrichtung wirkt also als Relais, dessen Empfindlichkeit man besonders groß machen kann, wenn man die ganze Anordnung durch eine besondere (nicht gezeichnete-) Temperiervorrichtung aufeiner geeigneten Temper atur nahe unterhalb des Schmelzpunktes des Salzes hält, so daß eine schwache Erwärm.u.ng durch den Heizstrom bereits den Effekt auslöst.At room temperature the salt is solid and practically insulating, circle V is open. If a current now flows through V2, A is heated, the salt becomes the conductor and circuit V1 is closed, the current itself contributing to the heating and thus to improving the conduction of the salt. The device thus acts as a relay, the sensitivity of which can be made particularly high if the entire arrangement is kept at a suitable temperature close to the melting point of the salt using a special (not shown) temperature control device, so that a slight warming the heating current already triggers the effect.
