Isolator für Außenraum-KlimaInsulator for outdoor climate
Die Erfindung betrifft einen Isolator für Außenraum-Klima nach dem Oberbegriff des Patentanspruchs 1.The invention relates to an insulator for outdoor air conditioning according to the preamble of claim 1.
Außenraum-Klima tritt z.B. in blechgekapselten Netzstationen auf und führt zeitweilig zur Bildung von Kondenswasser an Isolatoren, wodurch deren Spannungsfestigkeit vermindert wird und unter Umständen eine Schädigung eintritt. Um diese Erscheinungen zu vermeiden, hat man im Innern solcher Stationen entweder eine allgemein wirkende Konvektionsheizung mit unerwünschter Mobilisierung der Raumfeuchtigkeit durch Lufterwärmung oder neuerdings eine Konduktionsheizung am Stützer-Trageisen ohne nennenswerte Lufterwärmung vorgesehen. Zu diesem Zweck ist in beiden Fällen ein relativ hoher Energiebedarf bis 600 ¥ je Station notwendig, wovon dem einzelnen Isolator nur ein Bruchteil zugute kommt. Die Heizenergie muß aus einem Hilfsstromnetz entnommen werden.Outdoor climate occurs e.g. in sheet metal-encapsulated network stations and temporarily leads to the formation of condensation on insulators, whereby their dielectric strength is reduced and, under certain circumstances, damage entry. In order to avoid these phenomena, one either has a general operating one inside such stations Convection heating with undesirable mobilization of room humidity through air heating or more recently A conduction heater is provided on the Stützer carrying iron without any significant air heating. For this purpose, in In both cases, a relatively high energy requirement of up to ¥ 600 per station is necessary, of which only the individual isolator a fraction benefits. The heating energy must be taken from an auxiliary power supply.
Der Erfindung liegt die Aufgabe zugrunde, ohne Energieversorgung aus einem Hilfsnetz und mit wesentlich gerin-The invention is based on the object, without power supply from an auxiliary network and with significantly low

gerem Energiebedarf je Station auszukommen, um eine schädliche Kondenswasserbildung an den Isolatoren zu vermeiden. lower energy requirements per station to manage one to avoid damaging condensation on the insulators.
Die Lösung der gestellten Aufgabe gelingt auf einfache und sichere Weise nach der Erfindung durch die Maßnahmen nach den kennzeichnenden Merkmalen des Patentanspruchs 1.The object is achieved in a simple and safe manner according to the invention by means of the measures according to the characterizing features of claim 1.
Auf diese Weise kann eine Konvektionsheizung des Innenraumes z.B. solcher Stationen überhaupt vermieden und die Energie für die Erwärmung der Isolatoren direkt und zur notwendigen Zeit aus dem Hochspannungsnetz ohne Schaltaufwand entnommen werden. Die die ausreichende Erwärmung der Isolatoren erzwingenden inneren Verluste im Isolator können als ohmsche Verluste, z.B. durch Beimengung von Ruß, oder durch eine Ladungsverschiebung im Wechselfeld erzeugende gegeneinander isolierte Metallteilchen im Gießharz des Isolators erzeugt werden.In this way, a convection heating of the interior E.g. such stations are avoided at all and the energy for heating the insulators directly and for necessary time can be taken from the high-voltage network without switching effort. The sufficient warming The internal losses in the insulator that enforce the insulators can be seen as ohmic losses, e.g. due to the addition of Soot, or mutually isolated metal particles generated by a charge shift in the alternating field in the Cast resin of the insulator are produced.
Sine besonders vorteilhafte Lösung des Problems hinsichtlich Alterung und genauer Reproduzierbarkeit des Heizeffektes läßt sich durch die Verwendung von Streckmitteln mit wesentlich größerem Verlustwinkel tan£ als bei Gießharz erreichen, wobei diese Streckmittel gegebenenfalls zur Erhöhung der Feldstärken außerdem auch noch eine wesentlich niedrigere Dielektrizitätskonstante DK als Gießharz besitzen sollen. Diese Forderungen werden z.B. von Polyvinylchlorid in Form von dem flüssigen Gießharz beigemengten Granulat oder durch Eukryptit als Streckmittelersatz erfüllt. Die Menge des Streckmittels ist dabei so zu bemessen, daß eine ausreichende Verlustleistung im Isolator entsteht, die nach vorliegenden Erkenntnissen bei 1 bis 2 Watt je Mittelspannungs-Isolator liegt. Bei anderen Isolatoren können sich andere Leistungen als vorteilhafter erweisen.Its particularly advantageous solution to the problem with regard to Aging and exact reproducibility of the heating effect can be achieved through the use of extenders Achieve tan £ with a much larger loss angle than with cast resin, with these extenders if necessary to increase the field strengths also a significantly lower dielectric constant DK than Cast resin should have. These requirements are met e.g. by polyvinyl chloride in the form of the liquid casting resin added granules or eucryptite as an extender substitute. The amount of extender is to be dimensioned in such a way that there is sufficient power loss in the isolator, according to available knowledge is 1 to 2 watts per medium voltage isolator. With other isolators, different performances than prove more beneficial.
