Description

Anordnum!. zur Herabsetzung der Temperaturabhängigkeit der Ansprechspannung von Funkenstrecken Bei Untersuchungen an überspannungsableitern, welche Funkenstreckenanordnungen enthalten, wurdegefunden, daß die Ansprechspannung der Funkenstreckenanordnung mitunter ziemlich stark von der Temperatur der Umgebung der Elektroden abhängt. Es zeigte ,ich, daß die Ansprechspannung oberhalb der normalen Raumtemperatur (2o' C) ziemlich gleichmäßig ansteigt, bei niedrigeren Temperaturen aber, insbesondere in der Umgebung von o', rasch abfällt. Besonders stark ist die Temperatürabhängigkeit der Ansprechspannung bei Kugelfunkenstrecken; sie ist um so größer, je größer das Verhältnis der Funkenstreckenlänge zum Kugelradius ist. Daraus können sich insbesondere für Überspanliungsableiter, die in kalten Gegenden aufgestellt werden, unter Umständen Nachteile er-,geben.Order number !. To reduce the temperature dependency of the response voltage of spark gaps In investigations on surge arresters which contain spark gap arrangements, it was found that the response voltage of the spark gap arrangement sometimes depends quite strongly on the temperature of the surroundings of the electrodes. It showed, I, that the response voltage rises fairly steadily above normal room temperature (2o 'C) , but drops rapidly at lower temperatures, especially in the vicinity of o'. The temperature dependence of the response voltage is particularly strong in the case of spherical spark gaps; the greater the ratio of the spark gap length to the radius of the sphere , the greater it is. This can lead to disadvantages, especially for surge arresters that are installed in cold areas.

Ein Mittel, uni diesen Nachteilen wirksam entgegenzutreten, besteht erfindungsel gemäß darin, daß der Temperatureinfluß auf die Ansprechspannung durch eine den Raum zwischen den Elektroden, von denen die Ansprechspannung abhängig ist, abschirmende, höchstens mit einer Elektrode galvanisch verbundene Urnmantelung aus stränileitendem, insbesondere metallischem Stoff herabgesetzt wird.There is one means of effectively counteracting these disadvantages erfindungsel according to the fact that the temperature influence on the response voltage through one the space between the electrodes, on which the response voltage depends, shielding, at most galvanically connected to one electrode strand conductive, in particular metallic material is reduced.

Die Abbildung zeigt ein Ausführtiligsbeispiel. 1, :2 sind die kugel- oder pilzähnlichen Elektroden . der luftdicht abgeschlossenen Vorfunkenstrecke eines überspannungsleiters, die einander im Innern eines Isolierrohres 3 g - e, genüberstehen. 4 ist ein außen, auf dei n ,sölierrolir 3 angeordneter -Metallbelag, der mit der Elektrode i durch eine Leitung 5 verbunden ist. Er schirmt die Funkenstreckenanordnu ing auf ihrer ganzen Länge ab.The illustration shows an example of execution. 1,: 2 are the spherical or mushroom-like electrodes . the airtight pre-spark gap of a surge conductor, which face each other inside an insulating tube 3 g - e. 4 is a metal coating arranged on the outside of the roller 3 , which is connected to the electrode i by a line 5 . It shields the spark gap arrangement over its entire length.

Die Ausführbarkeit und Anwendbarkeit des Erfindungsgedankens ist nicht auf Vor-Z5 funkenstrecken für Überspannungsableiter, wie sie in der Zeichnung als Ausführungsbeispiel dargestellt sind, beschränkt. Die Erfindung läßt sich vielmehr auch bei Löschfunkenstrecken sowie sonst überall dort, wo es- auf die möglichst genaue Einhaltung der Ansprechspannung von Funkenstrecken ankommt, als Mittel zur 'Verminderung der Temperaturabhängigkeit des Ansprechens vorteilhaft anwenden.The feasibility and applicability of the inventive concept is not on pre-Z5 spark gaps for surge arresters, as shown in the drawing as Embodiment shown are limited. Rather, the invention can be also with extinguishing spark gaps as well as everywhere else where it is possible Precise compliance with the response voltage of spark gaps matters as a means of '' Take advantage of reducing the temperature dependence of the response.
