  Blitzschutzvorrichtung. 



   In unserem österreichischen Privilegium vom   30.   Mai   1896, Reg. Bd. 46,   S. 2141, verwenden wir Relais, um eine beliebige Anzahl von Stromkreise von irgend einem von diesen Stromkreisen räumlich entfernten Orte aus zu öffnen oder zu schliessen. In der Praxis hat sich herausgestellt, dass es nothwendig ist, die Relais vor atmosphärischen Entladungen zu schützen, und diesem Zwecke soll die nachfolgend beschriebene Blitzschutzvorrichtung dienen. 



   Auf dem Porzellansockel A ist der   Eisenkörper   des Relais festgeschraubt, welcher die Spule B des Relais trägt. Der Strom zur Erregung derselben wird durch die beiden Klemmen C1 und   C2 zugeführt.   An diesen Klemmen sind zwei   Federn aus Mesng   angebracht, in welche ein   Stäbchen 7),   bestehend aus einem relativ   schiechtem E) ektricitäts-   leiter eingeklemmt wird. Als Material hierfür kommt Graphit oder Kohlenpulver in ent-   sprechender   Mischung mit Nichtleitern zur Verwendung. 



   Wie aus dem Schaltungsplan ersichtlich ist, wird dieses Stäbchen im   Kebensphius5   zur Spule geschaltet ; da der Widerstand desselben ein Vielfaches der Spulenwickiung ist, wird der grösste Theil des zur Erregung des Relais durchfliessenden Gleichstromes durch die   SptUpnwindungen   gehen, während bei atmosphärischen Entladungen die Selbstinduction   d''r Spule denselben   einen viel grösseren Widerstand entgegensetzt als das von SelbstinductionfreieWiderstandsstäbchenD. 

**WARNUNG** Ende DESC Feld kannt Anfang CLMS uberlappen**.

  Lightning protection device.



   In our Austrian Privilegium of May 30, 1896, Reg. Vol. 46, p. 2141, we use relays to open or close any number of circuits from any location that is spatially distant from these circuits. In practice it has been found that it is necessary to protect the relays from atmospheric discharges, and the lightning protection device described below is intended to serve this purpose.



   The iron body of the relay, which carries the coil B of the relay, is screwed onto the porcelain base A. The current for exciting the same is supplied through the two terminals C1 and C2. Two springs made of brass are attached to these clamps, into which a rod 7), consisting of a relatively poor electrical conductor, is clamped. The material used for this is graphite or carbon powder in a corresponding mixture with non-conductors.



   As can be seen from the circuit diagram, this rod is connected to the coil in Kebensphius5; Since its resistance is a multiple of the winding of the coil, the greater part of the direct current flowing through to excite the relay will go through the voltage windings, while in atmospheric discharges the self-induction of the coil opposes it with a much greater resistance than that of the self-induction-free resistance rod.
