TECHNISCHES GEBIETTECHNICAL AREA

Die Erfindung geht aus von einem Isolator gemäss dem Oberbegriff der Ansprüche 1 und 2.The invention is based on an isolator according to the The preamble of claims 1 and 2.

STAND DER TECHNIKSTATE OF THE ART

Herkömmliche Isolatoren, insbesondere Isolatoren, die in Energieversorgungsanlagen unter Freiluftbedingungen betrieben werden, müssen von Zeit zu Zeit gereinigt werden, um Ablagerungen an der Oberfläche der Isolatoren zu entfernen, die eventuell die Spannungsfestigkeit der Isolatoren beeinträchtigen könnten. Derartige Reinigungsarbeiten werden periodisch durchgeführt, in Gebieten mit einer grossen Luftverschmutzung müssen diese Wartungsarbeiten vergleichsweise häufig durchgeführt werden. Durch derartige Wartungsarbeiten wird die Verfügbarkeit der Energieversorgungsanlagen reduziert.Conventional insulators, especially insulators that are used in Energy supply systems operated under open air conditions need to be cleaned from time to time Remove deposits on the surface of the insulators, possibly the dielectric strength of the insulators could affect. Such cleaning work will be carried out periodically, in areas with a large Air pollution need this maintenance be carried out comparatively often. Through such Maintenance work will affect the availability of the Energy supply systems reduced.

Aus der Patentanmeldung EP 0 772 514 A1 sind selbst reinigende Oberflächen und Verfahren für die Herstellung derartiger Oberflächen bekannt. Die Selbstreinigungsfähigkeit derartiger Oberflächen beruht auf dem von der Lotuspflanze her bekannten sogenannten Lotus-Effekt®, der durch eine spezielle Mikrostruktur der Oberfläche hervorgerufen wird. Die Blätter der Lotusblume sind nicht dauerhaft benetzbar, sie präsentieren sich unmittelbar nach jedem Regen trocken und sauber, da das Regenwasser sogleich von der Blattoberfläche abperlt und dabei eventuell vorhandene Schmutzpartikel mitreisst. Die Ursache für dieses Abperlen ist eine spezielle Mikrostruktur der Oberfläche der Blätter.From the patent application EP 0 772 514 A1 are self-cleaning Surfaces and processes for making such Known surfaces. The self-cleaning ability of such Surfaces is based on that known from the lotus plant the so-called Lotus Effect®, which is characterized by a special Microstructure of the surface is caused. The leaves the lotus flower are not permanently wettable, they present themselves dry and dry immediately after each rain clean because the rainwater immediately from the leaf surface  rolls off and any dirt particles present traveling with you The cause of this beading is a special one Microstructure of the surface of the leaves.

Ferner ist eine Farbe "ispo Lotusan" der Firma ispo GmbH, Gutenbergstr. 6, D 65830 Kriftel bei Frankfurt a. M., bekannt, die als Fassadenfarbe eingesetzt wird. Die Oberfläche dieser Farbe bildet sich nach dem Auftragen so aus, dass sie diese Mikrostruktur aufweist, die das Auftreten des Lotus-Effekts® ermöglicht. Diese Farbe verhindert, dass sich an der Fassade des Hauses Schmutzpartikel auf Dauer festsetzen können, da bei jedem Regen eine Selbstreinigung der mit dem Regen in Berührung kommenden Fassadenoberfläche stattfindet. Die Farbe "ispo Lotusan" der Firma ispo GmbH, ist auf Siliconbasis hergestellt.There is also a color "ispo Lotusan" from ispo GmbH, Gutenbergstrasse 6, D 65830 Kriftel near Frankfurt a. M., known, which is used as facade paint. The surface of this Color forms after application so that it Has microstructure that the appearance of the Lotus Effect® enables. This color prevents it from sticking to the facade of the house can permanently fix dirt particles because every rain a self cleaning with the rain in Touching facade surface takes place. The color "ispo Lotusan" from ispo GmbH is based on silicone manufactured.

DARSTELLUNG DER ERFINDUNGPRESENTATION OF THE INVENTION

Die Erfindung, wie sie im unabhängigen Anspruch gekennzeichnet ist, löst die Aufgabe, einen Isolator zu schaffen, der eine bessere betriebliche Verfügbarkeit aufweist.The invention as characterized in the independent claim solves the task of creating an isolator that is one has better operational availability.

Die durch die Erfindung erreichten Vorteile sind darin zu sehen, dass durch den Selbstreinigungseffekt die Wartungsarbeiten am Isolator, insbesondere die Reinigung der äusseren Oberfläche desselben, in erheblich grösseren Zeitabständen erfolgen können. In Gebieten, wo die Luftverschmutzung nicht allzu intensiv ist, kann sogar auf die spezielle Reinigung der Isolatoroberfläche völlig verzichtet werden, was eine erhebliche Einsparung bei den Betriebs- und Unterhaltskosten zur Folge hat.The advantages achieved by the invention are there too see that through the self-cleaning effect Maintenance work on the isolator, especially cleaning the outer surface of the same, in considerably larger Intervals can take place. In areas where the Air pollution is not too intense, can even affect that special cleaning of the insulator surface completely dispensed with be what a significant saving in operating and Has maintenance costs.

WEGE ZUR AUSFÜHRUNG DER ERFINDUNGWAYS OF CARRYING OUT THE INVENTION

Es ist sinnvoll, insbesondere Isolatoren für Freiluftanwendungen an der Oberfläche mit Beschichtungen zu versehen, welche unter Ausnutzung des Lotus-Effekts® eine Selbstreinigung der Oberfläche des Isolators ermöglichen. Geeignet für eine derartige Beschichtung ist die Farbe "ispo Lotusan" der Firma ispo GmbH. Diese Farbe ist auf einer Siliconbasis hergestellt, sie weist deshalb die für diese Anwendung nötige dielektrische Festigkeit auf.It makes sense, especially for isolators Outdoor applications on the surface with coatings too provided which, using the Lotus-Effect®, a Allow self-cleaning of the surface of the insulator. The color "ispo" is suitable for such a coating Lotusan "from ispo GmbH. This color is on one Manufactured silicone base, it therefore has the for this Application required dielectric strength.

Isolatoren mit glatter Oberfläche werden auf der gesamten Oberfläche mit der Farbe "ispo Lotusan" beschichtet. Mit Rippen versehene Isolatoren werden vorteilhaft nur an den direkt vom Regen benetzbaren Stellen mit der Farbe "ispo Lotusan" beschichtet.Insulators with a smooth surface are used on the whole Surface coated with the color "ispo Lotusan". With Ribbed insulators are advantageous only on the places directly wettable by rain with the color "ispo Lotusan "coated.

Es ist noch eine Vielzahl von Beschichtungsmaterialien für Isolatoren vorstellbar, deren Oberflächen aufgrund des Lotus- Effekts® selbstreinigend wirksam sind, neben den verschiedensten Lacken auf Siliconbasis ist es aber auch vorstellbar, bei der Isolatorherstellung dem Grundmaterial bereits Materialkomponenten so beizumischen, dass die sich ausbildende Oberfläche des Isolators aufgrund des Lotus- Effekts® wirksam werden kann.There is still a wide variety of coating materials for Isolators conceivable, whose surfaces due to the lotus Effekt® are self-cleaning, in addition to It is also a wide variety of silicone-based paints conceivable, the base material in the manufacture of insulators already mix material components in such a way that the forming surface of the insulator due to the lotus Effect® can take effect.

Die beschriebene Beschichtung kann sowohl bei Kunststoffisolatoren als auch bei Keramikisolatoren vorgenommen werden. Bei Keramikisolatoren kann es sinnvoll sein, die Materialien, die den Lotus-Effekt® hervorrufen, bereits in die Glasur des Isolators einzubringen, sodass die Oberfläche der Glasur aufgrund des Lotus-Effekts® wirksam werden kann, ohne dass eine weitere Beschichtung des Isolators nötig ist.The coating described can both Plastic insulators as well as ceramic insulators be made. It can be useful for ceramic insulators the materials that create the Lotus Effect®, already in the glaze of the insulator, so that Glaze surface effective due to the Lotus Effect®  can be made without further coating of the insulator is necessary.

Derartige Isolatoren können beispielsweise als Durchführungen, als Trag- oder Stützisolatoren, als Hülle von Überspannungsableitern und als Gehäuse von Leistungsschaltern oder Trennern eingesetzt werden. Daneben gibt es noch eine Vielzahl von weiteren Anwendungen in der Elektrotechnik. Es ist auch vorstellbar, dass Isolatoren, die für Innenraumanwendungen vorgesehen sind, mit dieser speziell ausgebildeten Oberfläche versehen werden, um diese mittels Abspritzens rasch und zuverlässig von angelagerten Partikeln befreien zu können.Such insulators can be used as bushings, as support or support insulators, as a casing of Surge arresters and as housings for circuit breakers or separators are used. There is also another one Numerous other applications in electrical engineering. It it is also conceivable that isolators used for Indoor applications are provided with this specifically trained surface to be provided by means of Spraying away quickly and reliably from accumulated particles to be able to free.
