Die bei häufigen kurz hintereinander stattfindenden Entladungen eintretende Erhitzung der Elektroden von Blitzableitern, welche z. B. aus stabförmigen Hörnern bestehen, kann leicht zu einer Schmelzung der Elektroden führen. Tritt ein solcher Vorgang ein, so wird die Länge der Funkenstrecke verändert. Es wird also die Funkenstrecke nicht mehr bei derjenigen Spannung ansprechen, für welche sieThe heating that occurs when discharges occur frequently in quick succession the electrodes of lightning rods, which z. B. consist of rod-shaped horns can easily lead to a melting of the electrodes. If such a process occurs, the Length of the spark gap changed. So the spark gap is no longer there Address tension for which they
ίο ursprünglich eingestellt worden , war. Falls durch das Schmelzen der Elektroden die Funkenstrecke vergrößert worden ist, so wird die Spannung im* Netz höher steigen, als die ursprüngliche Einstellung der Funkenstrecke zulassen sollte, und wird die Anlage gefährden. Im anderen Falle (bei einer Verkürzung der Funkenstrecke) wird ein dauerndes Arbeiten derselben mit der Betriebsspannung der "Anlage stattfinden.ίο was originally set. If by melting the electrodes the If the spark gap has been increased, the voltage in the network will rise higher than the original setting of the spark gap should allow and will endanger the system. In the other case (if the spark gap is shortened) a permanent The same work takes place with the operating voltage of the "system.
Diese Übelstände werden durch vorliegende Erfindung beseitigt, welche die Anwendung kastenförmiger, aus Blech oder dünnem Guß.These inconveniences are eliminated by the present invention, which the application box-shaped, made of sheet metal or thin cast.
hergestellter Elektroden zum Gegenstand hat.manufactured electrodes.
Fig. ι zeigt die Vorderansicht,- Fig. 2 die Seitenansicht einer Funkenstrecke A mit den Elektroden E; n> ist der Erregerwiderstand und W der Vorschaltwiderstand der Funkenstrecke. Fig. 1 shows the front view, - Fig. 2 shows the side view of a spark gap A with the electrodes E; n> is the excitation resistance and W is the series resistance of the spark gap.
Da jede Elektrode zwei Seitenplatten hat, deren jede wi-ederum zwei Abkühlungsflächen besitzt, so sind an jeder Elektrode vier Abkühlungsflächen vorhanden, welche die Wärme an die umgebende Luft abgeben.Since each electrode has two side plates, each of which in turn has two cooling surfaces has, there are four cooling surfaces on each electrode, which the heat release to the surrounding air.
Es sind ,zwar . Blitzableiterelektroden mit großen Abkühlungsoberflächen bekannt. Gegenüber diesen Einrichtungen wird aber bei dem Gegenstand der Erfindung durch die kastenförmige Ausbildung der Elektroden der Vorteil erreicht, daß ein lebhafter Luftwechsel in dem durch die beiden Wäride ge- bildeten Hohlräume und eine vergrößerte Abgabe der Wärme an die Luft eintritt. Zugleich mit diesen Eigenschaften verbindet die vorliegende Konstruktion noch Leichtigkeit bei sehr großer Stabilität.There are, though. Known lightning conductor electrodes with large cooling surfaces. Opposite to but these facilities is in the subject matter of the invention by The box-shaped design of the electrodes has the advantage that a lively exchange of air in the area created by the two heats formed cavities and an increased release of heat to the air occurs. Simultaneously the present construction combines these properties with lightness with very high stability.
