  Luftleerblitzableiter mit bei Oberlastung selbsttätig in Wirkung tretendem Kurzschluss der Elektroden. 
 EMI1.1 
 bestehen   bleibt, so dass der Blitzableiter ausgeweclselt werden muss.   



   Gemäss der Eitindung wird dieser Nachteil dadurch vermieden, dass für die   Kurzschluss-   
 EMI1.2 
 zusammengesetzten Schaltkörpern sind an   sich bekannt.   Die Anwendung dieser Einrichtung ist aber von besonderem Vorteil für die   Luftleerblitzableitcr, bei denen   die Elektroden in einem luftdicht geschlossenen Behälter eingeschlossen sind, der jede Nechregulierung der Funken-   Strecken unmöglich   macht. 
 EMI1.3 
 Die beiden an den einander zugewendeten Flächen mit Riffelungen versehenen Elektroden a werden   durch seitliche Plattenb aus Isoliermaterial   in unverfändertem Abstand ovneinander gehalten.

   An der einen Elektrode ist ein in der   Mitte U-förmig   gebogener Streifen c befestigt, der aus zwei Metallen mit verschiedenem Ausdehnungskoeffizienten besteht. An der unteren Elektrode ist ein Kontakt   J     angeordnet, welcher von dem freien Ende des Streifens c berührt wird. sobald dieser durch den Strom-   ül) ergang am eigentlichen Blitzableiter   ein''gewisse Erwärmung   erfahren hat und infolge der ver-

Der Blitzableiter ist in ein patronenartiges   Glasgehäuse g eingeschlossen, welehes luftleer   ge-   macht ist.   Dieselbe   Einrichtung lässt. sich natürlich   auch an gewöhnlichen Blitzableitern anbringen.

 EMI1.1
 remains in place so that the lightning rod has to be disconnected.



   According to the conception, this disadvantage is avoided by the fact that for the short-circuit
 EMI1.2
 composite switching bodies are known per se. The use of this device is of particular advantage for the Luftleerblitzabitcr, in which the electrodes are enclosed in an airtight container, which makes any adjustment of the spark gap impossible.
 EMI1.3
 The two electrodes a provided with corrugations on the surfaces facing one another are held at an unchanged distance ovn one another by lateral plates b made of insulating material.

   A strip c, which is bent in a U-shape in the center and consists of two metals with different expansion coefficients, is attached to one electrode. A contact J, which is contacted by the free end of the strip c, is arranged on the lower electrode. as soon as this has experienced a certain warming due to the current on the actual lightning rod and as a result of the
 EMI1.4
 
The lightning conductor is enclosed in a cartridge-like glass housing g which has been evacuated. The same facility leaves. Of course, they can also be attached to ordinary lightning rods.
