Abstract
Description
Die Erfindung betrifft einen feldgesteuerten Verbundisolator gemäß dem Oberbegriff des ersten Patentanspruchs.The invention relates to a field-controlled composite insulator according to the preamble of the first claim.
Wie aus der
Eine weitere Ursache sind die Schmutzablagerungen, eine Belastung, die einen Verbundisolator insgesamt betrifft. Auf Verbundisolatoren, die als Außeninstallationen der Witterung ausgesetzt sind, lagern sich mit der Zeit dünne Schmutzschichten ab. Auf Grund der elektrischen Leitfähigkeit dieser Schichten können auf den Isolatoroberflächen Ladungsstöme fließen. Werden diese Schichten feucht, beispielsweise durch Regen oder Tau, wird die Leitfähigkeit noch weiter erhöht, was zu erhöhten Stromstärken der Leck- und Entladeströme und zu ohmschen Verlusten führt. Das bewirkt eine Erwärmung der Schmutzschichten mit der Folge ihrer Abtrocknung. Diese werden lokal hochohmig, so dass hohe Spannungsabfälle auftreten können. Wird dadurch bedingt die elektrische Duchschlagsfestigkeit der Umgebungsluft überschritten, treten Glimmentladungen oder elektrische Überschlagsentladungen auf, die die Ursache für eine Alterung und schließlich Zerstörung des Werkstoffs der Isolatoroberfläche sind.Another cause is the dirt deposits, a burden that affects a composite insulator as a whole. On composite insulators, which are exposed to outdoor weather conditions, thin layers of dirt deposit over time. Due to the electrical conductivity of these layers, charge currents can flow on the insulator surfaces. If these layers become moist, for example due to rain or dew, the conductivity is increased even further, which leads to increased currents of the leakage and discharge currents and to ohmic losses. This causes a heating of the dirt layers with the result of their drying. These become locally high-impedance, so that high voltage drops can occur. If this causes the electrical impact strength of the ambient air to be exceeded, glow discharges or electrical flashover discharges occur, which are the cause of aging and finally destruction of the material of the insulator surface.
Als Maßnahme zur Homogenisierung des elektrischen Feldes und zur Vermeidung örtlicher Feldstörung, werden örtliche Überzüge oder Beschichtungen aus Isolierwerkstoffen, beispielsweise Kunststoffen wie Epoxidharze oder Polymere, mit Einlagerungen aus dielektrischen und/oder ferroelektrischen Stoffen als Feldsteuerschichten aufgebracht.As a means of homogenizing the electric field and avoiding local field disturbance, localized coatings or coatings of insulating materials, such as plastics such as epoxy resins or polymers, are applied with field interlayers of dielectric and / or ferroelectric materials as field control layers.
Auch aus der
Der Stand der Technik weist im Wesentlichen zwei große Nachteile auf, nämlich das Verfahren zum Aufbringen der Feldsteuerschicht sowie die Steuerung der Eigenschaften dieser. Zum Extrudieren der Feldsteuerschicht auf den Kern, muss das verwendete Material als Füllstoff in ein schmelzbares Grundmaterial eingebracht werden. Es ist somit nicht möglich, nur das feldsteuernde Material unmittelbar auf den Kern aufzubringen. Das Extrudieren an sich geschieht stets vollflächig, d. h. die Feldsteuerschicht umschließt den gesamten Kern. Um die Eigenschaften der Feldsteuerschicht gezielt regulieren zu können, müssen das Mischverhältnis von Füllstoff und dem feldsteuernden Material oder die aufgebrachte Schichtdicke verändert werden. Beim Vermischen des feldsteuernden Grundmaterials mit dem Füllstoff muss stets sichergestellt werden, dass das Gemisch homogen ist. Dies ist aufwendig und kostenintensiv.Essentially, the prior art has two major drawbacks, namely, the method of applying the field control layer and controlling the characteristics thereof. To extrude the field control layer onto the core, the material used must be introduced as a filler into a fusible base material. It is thus not possible to apply only the field-controlling material directly to the core. The extrusion itself always happens over the entire surface, d. H. the field control layer encloses the entire core. In order to be able to regulate the properties of the field control layer in a targeted manner, the mixing ratio of filler and the field-controlling material or the applied layer thickness must be changed. When mixing the field-controlling base material with the filler, it must always be ensured that the mixture is homogeneous. This is expensive and expensive.
Aufgabe der vorliegenden Erfindung ist es einen Verbundisolator mit einer Feldsteuerschicht bereitzustellen, bei dem die Eigenschaften der Feldsteuerschicht einfach und präzise während der Herstellung gesteuert werden können.The object of the present invention is to provide a composite insulator with a field control layer in which the properties of the field control layer can be easily and precisely controlled during manufacture.
Diese Aufgabe wird durch einen Verbundisolator mit einer Feldsteuerschicht gelöst, bei dem die Feldsteuerschicht mit Hilfe von Plasmabeschichtung aufgebracht ist und dabei die Eigenschaften der Feldsteuerschicht durch deren Material und geometrische Struktur verändert werden können.This object is achieved by a composite insulator with a field control layer, in which the field control layer is applied by means of plasma coating and in the process the properties of the field control layer can be changed by its material and geometric structure.
