Eiektrowerke Akt.-Ges. in Berlin*).Eiektrowerke Akt.-Ges. in Berlin*). Hängeisolator mit gegen Staubablagerung geschützten Flächen.Suspension insulator with surfaces protected against dust deposits. Patentiert im Deutschen Reiche vom 5. Juli 1923 ab.Patented in the German Empire on July 5, 1923.

Hängeisolatoren in Tellerform erhalten an der Unterseite gewöhnlich eine Anzahl von Rippen, die als Tropfkanten und zur Vergrößerung der Übers'chlagsicherheit dienen, da die zwischen den Rippen liegenden Räume möglichst trockene Strecken mit großem elektrischen Widerstand schaffen sollen. Erreicht wird dies auch z. B. bei Regen, jedoch nicht mehr bei vernebelter Luft, die ebenfalls in ίο die Vertiefungen eindringt und Wasserbläschen an den Porzellanflächen absetzt. Immerhin ist der Leitwiderstand noch praktisch groß genug, solange die Bläschen sich nicht -zu einem zusammenhängenden Faden längs der elektrischen Kraftlinien vereinigen. Nun hat man in Gegenden mit staubhaltiger Luft beobachtet, daß sich in den Innenräumen zwischen den Rippen der Tellerisolatoren in kurzer Zeit eine starke rauhe Schicht von Staubteilchen bildet, die mit Feuchtigkeit ge- ao sättigt eine gut leitende Zone auf der Porzellanfläche darstellt und dadurch den Isola-Suspension insulators in plate shape usually have a number of at the bottom Ribs, which serve as drip edges and to increase safety against rollover, because the spaces between the ribs are as dry as possible with large electrical lines To create resistance. This is also achieved z. B. in the rain, but not more with nebulized air, which also penetrates into ίο the depressions and water bubbles settles on the porcelain surfaces. After all, the conductive resistance is still practically large enough as long as the bubbles do not move -unite to a coherent thread along the electrical lines of force. so has been observed in areas with dusty air that inside between the ribs of the plate insulators in a short time a thick, rough layer of Dust particles which, when saturated with moisture, form a highly conductive zone on the porcelain surface represents and thereby the Isola

tionswert gegenstandslos macht. Erfahrungsgemäß treten an solchen verunreinigten Isolatoren Überschläge und Zerstörungen ein, die bei Nehelwetter zu schweren Betriebsstörungen führen können. Die häufige Reinigung der Isolatoren ist ein lästiges und kostspieliges Verfahren. Auch in Gegenden mit verhältnismäßig reiner Luft finden sich diese Ablagerungen, wenn auch erst nach längererrenders value irrelevant. Experience has shown that such contaminated insulators occur Flashovers and destruction, which in bad weather can lead to serious operational disruptions being able to lead. Frequent cleaning of the isolators is a tiresome and costly one Procedure. These deposits can also be found in areas with relatively clean air, even if only after a longer period of time

ίο Zeit. Gegenstand der Erfindung ist die Gestaltung der unteren Rippen derart, daß eine natürliche Reinigung durch den Wind möglich ist. Die Staub-, Ruß- und Kohleteilchen werden mit dem Winde herangeführt und vermögen sich, da an den vom Winde abgekehrten steilen Flächen der senkrechten Rippen, wie sie bisher üblich waren, Wirbel entstehen, dort abzusetzen. Die Erscheinung der Ablagerung ist im allgemeinen auch nur ein-ίο time. The subject of the invention is the design the lower ribs in such a way that natural cleaning by the wind is possible. The dust, soot and coal particles are brought up with the wind and are able to approach those who have turned away from the wind steep surfaces of the vertical ribs, as they were usual up to now, create vortices, drop off there. The appearance of the deposit is generally only one

ao seitig. Wie die Zeichnung zeigt, sind bei der Ausführung nach Abb. 1 die Rippen eines an sich bekannten Hängekappenisolators so nach außen gebogen, daß ihre Kanten gegen den Wind stehen und die heranfließende Luftströmung so teilen, daß auch die nach unten as geneigten inneren Flächen kräftig vom Winde bestrichen werden. Eine Wirbelung tritt dann nicht mehr ein. Der Wind wird vielmehr den Zwischenraum der Rippen kräftig durchstreichen und vorhandene Ablagerungen abtragen. Die Ausführung nach Abb. 2 stellt eine andere Lösung dar, bei der die oberen Flächen der Rippen senkrecht gestellt werden. ao sided. As the drawing shows, in the embodiment according to Fig. 1, the ribs are one known hanging cap insulator so bent outward that its edges against stand the wind and divide the incoming air flow so that the downward as inclined inner surfaces are brushed vigorously by the wind. A vortex then occurs no longer one. Rather, the wind will forcefully sweep the space between the ribs and remove existing deposits. The embodiment according to Fig. 2 represents a Another solution is in which the upper surfaces of the ribs are made perpendicular.
