Description

Verfahren zum Herstellen eines eine glasfaserfreie Außenhaut aufweisenden Isolators Gegenstand der Erfindung ist ein Verfahren zum Herstellen eines eine glasfaserfreie Außenhaut aufweisenden Isolators, der ganz aus durch Kunstharz gebundenen Glasfasern besteht, wobei als: Bindemittel ein Epoxy-, Polyester- oder ein ähnliches Kunstharz verwendet wird und die Fertigung durch Pressen in einer Preßform erfolgt.Method for producing an outer skin having a glass fiber-free outer skin The invention relates to a method for producing a glass fiber-free insulator Insulator with outer skin, made entirely of glass fibers bound by synthetic resin consists, wherein as: binder an epoxy, polyester or a similar synthetic resin is used and the production is carried out by pressing in a die.

Erfindungsgemäß wird die Preßform vor dem Verpressen des Isolators mit einem Harzfilm versehen, der aus, dem gleichen Material wie das Bindemittel oder aus einem ähnlichen Harz bestehst, und dieser Harzfilm wird vor dem Verpressen an- oder ausgehärtet. Auf diese Weise erhält man einen mit dem gepreßten Isolator fest verpreßten Schutzüberzug, der völlig zuverlässig ist.According to the invention, the mold is made prior to the pressing of the insulator provided with a resin film made of the same material as the binder or made of a similar resin, and this resin film is made before pressing partially hardened or hardened. In this way one obtains one with the pressed insulator firmly pressed protective coating that is completely reliable.

Der Fachmann war bisher der Meinung, da,B ein absolut zuverlässiger Schutzüberzug nicht möglich ist, so daß es keinen Sinn habe, den ganzen Isolator zu überziehen. Er hat es aus diesem Grunde vorgezogen, die Oberflächenkriechstrecke eines Isolators aus Isolierstofffzonen verschiedener Feuchtigkeitsaufnahme aufzubauen, um eine bessere Kontrolle auf den Oberflächenkriechstrom zu erhalten; im Gegensatz zu den bisherigen die ,ganze Isolatoroberfläche bedeckenden Überzügen, die mit der Zeit eine unkontrollierbare Stromleitung aufweisen.Up to now, the expert has been of the opinion that B is an absolutely reliable one Protective coating is not possible, so there is no point in the whole insulator to cover. For this reason he preferred the surface creepage distance to build an insulator from insulating material zones of different moisture absorption, to have better control over the surface leakage current; in contrast to the previous coatings covering the entire insulator surface with the Time have an uncontrollable power line.

Daß der Fachmann mit einem die ganze Isolatoroberfläche erfassenden Schutzüberzug diese Schwierigkeiten hatte, liegt nach der der Erfindung zugrunde liegenden Erkenntnis: am Herstellungsverfahren. Bei nach der Erfindung hergestellten Überzügen bestehen die bisherigen Schwierigkeiten keinesfalls.That the expert can grasp the entire insulator surface with one Protective coating had these difficulties, is based on the invention Recognition: the manufacturing process. When made according to the invention The previous difficulties do not exist under any circumstances.

Die Erfindung ist für Isolatoren aller Art, die aus Glasfasern und Harz gepreßt werden, brauchbar, wie z. B. Hänge-, Stab-, Stütz- und Durchführungsisolatoren, von Bedeutung. Die Isolatoren können Glasfasern in Form von Gewebe aufweisen bzw. sie können mit in einer Richtung nebeneinanderliegenden oder regellos angeordneten Glasfasern, insbesondere aus alkalifreem Glas, versehen sein, wobei das verwendete Harz mit Silikonelösung modifiziert sein kann. Das Anwendungsgebiet für nach dem erfindungsgemäßen Verfahren hergestellte Isolatoren ist groß. Sie können in Hochspannungsschaltanlagen der Freiluft-, Hallen- oder Zellenbauweise Verwendung finden und auch in Freiluft- oder Innenraumverteilungsanlagen benutzt werden. Man kann sie bei Transformatoren., Trennschaltern, Druckgasschaltern und Ölströmungsschaltern gleichfalls vorsehen.The invention is applicable to all types of insulators made of fiberglass and Resin are pressed, usable such. B. suspension, rod, support and bushing insulators, significant. The insulators can have glass fibers in the form of fabric or they can be arranged side by side or randomly in one direction Glass fibers, in particular made of alkali-free glass, be provided, the used Resin can be modified with silicone solution. The area of application for after Insulators made according to the method of the invention is large. They can be used in high voltage switchgear the open-air, indoor or cell construction are used and also in open-air or indoor distribution systems are used. They can be found on transformers., Also provide disconnectors, gas pressure switches and oil flow switches.
