Description

Die Erfindung betrifft einen Hochspannungsisolator nach den Merkmalen des Oberbegriffs des ersten Patentanspruches.The invention relates to a high-voltage insulator according to the features of the preamble of the first claim.

Derartige Hochspannungsisolatoren sind beispielsweise aus der EP 1 091 365 bekannt geworden. Hierin wird ein Verfahren zur Herstellung eines hohlen Verbundstoffisolators beschrieben, der aus glasfaserverstärktem Epoxidharz mit einer Beschirmung aus Silikon hergestellt wird und dessen End- bzw. Anfangsstücke aus metallischen Flanschen, beispielsweise aus Aluminium, gebildet werden.Such high voltage insulators are for example from the EP 1 091 365 known. Described herein is a method of manufacturing a hollow composite insulator made of glass fiber reinforced epoxy resin with silicone shielding and whose end pieces are formed from metallic flanges, such as aluminum.

Das freie Innenvolumen von Verbundstoffisolatoren wird auf Grund elektrisch isolierender Eigenschaften insbesondere mit Schwefelhexafluorid, einer anorganisch chemischen Verbindung aus den Elementen Schwefel und Fluor mit der Summenformel SF6, befüllt. Grundsätzlich gilt es jedoch festzuhalten, dass auch jedwedes andere Isoliergas, beispielsweise Stickstoff, dafür in Frage kommt. SF6 ist unter Normalbedingungen ein farb- und geruchloses, ungiftiges Gas, das unbrennbar ist und sich äußerst reaktionsträge, ähnlich wie Stickstoff, verhält. Wegen seiner hohen Dichte, der hohen Ionisierungsenergie und der Eigenschaft, freie Elektronen zu binden, ist es in der Mittel- und Hochspannungstechnik ein gängig verwendetes Isoliergas.The free internal volume of composite insulators is due to electrical insulating properties in particular with sulfur hexafluoride, an inorganic chemical compound of the elements sulfur and fluorine filled with the empirical formula SF6. In principle, however, it should be noted that any other insulating gas, for example nitrogen, is also suitable. Under normal conditions SF6 is a colorless and odorless, non-toxic gas that is non-combustible and behaves extremely inert, similar to nitrogen. Because of its high density, the high ionization energy and the ability to bind free electrons, it is commonly used in medium and high voltage insulation gas.

Um die Wirksamkeit des verwendeten Isoliergases über die gesamte Lebensdauer der Verbundisolatoren zu gewährleisten, muss das freie Innenvolumen der Verbundstoffisolatoren gegenüber der äußeren Atmosphäre absolut dichtend ausgebildet sein. Dazu wird das freie Innenvolumen, d. h. der freie Gasraum, auf verschiedene Paramater hin überwacht.In order to ensure the effectiveness of the insulating gas used over the entire life of the composite insulators, the free internal volume of the composite insulators must be made absolutely sealed against the external atmosphere. For this purpose, the free internal volume, d. H. the free gas space, monitored for different parameters.

Hierfür ist beispielsweise aus der DE 196 35 362 ein Verfahren zur Herstellung eines gewickelten Hochspannungsisolators bekannt geworden, bei dem ein oder mehrere Kanäle für nachträglich einziehbare Leiter aller Art, insbesondere Lichtwellenleiter, vorgesehen sind. Dabei wird ein Laminataufbau durch Wickeln eines Materials auf einen Wickeldorn und Tränken mit einem Harz erreicht. Hierfür werden zunächst erste Lagen des aufzuwickelnden Materials aufgebracht, danach wird mindestens eine Nut in die entstandene Oberfläche eingearbeitet und anschließend fertiggewickelt, bis der gewünschte Enddurchmesser erreicht ist.For this example is from the DE 196 35 362 a method for producing a wound high-voltage insulator has become known in which one or more channels for subsequently retractable conductors of all kinds, in particular optical waveguides, are provided. In this case, a laminate structure is achieved by winding a material onto a winding mandrel and impregnating with a resin. For this purpose, first layers of the material to be wound are applied first, then at least one groove is incorporated into the resulting surface and then finished wound until the desired final diameter is reached.

Die DE 196 35 372 beschreibt ein Verfahren zur Herstellung eines Hochspannungsisolators, bei dem mindestens ein Leerkanal zum nachträglichen Einziehen eines Lichtwellenleiters vorgesehen wird. Hierfür werden erste Lagen des aufzuwickelnden Materials aufgebracht, danach wird ein mit mindestens einem Leerrohr vorgesehener Formkörper auf der entstanden Oberfläche fixiert und durch anschließend aufgewickelte Lagen eingewickelt.The DE 196 35 372 describes a method for producing a high-voltage insulator, in which at least one empty channel is provided for retrofitting an optical waveguide. For this purpose, first layers of the material to be wound are applied, then a with At least one empty tube provided shaped body fixed on the resulting surface and wrapped by subsequently wound layers.

All diesen bekannten Verfahren haften jedoch technisch nachteilige Aspekte an, die sich aus der Verwendung von Lichtwellenleitern zur Messwertübertragung ergeben: Um die Lichtwellenleiter an oder auch in dem Hochspannungsisolator vorsehen zu können, muss eine umlaufende Nut oder ein wie auch immer gearteter freier Hohlraum am oder im Hochspannungsisolator geschaffen werden, der den oder die Lichtwellenleiter aufnimmt. Eine mechanische Veränderung der Oberflächenstruktur der ansonsten homogenen Oberfläche des Hochspannungsisolators oder auch das Vorsehen eines wie auch immer gearteten Hohlraums ist jedoch aus Sicht der dielektrischen Festigkeit höchst problematisch und stellt in letzter Konsequenz eine mögliche Fehlstelle für elektrische Überschläge dar. Auch gibt es bei den bekannten Verfahren keine Möglichkeit, zu einem späteren Zeitpunkt, also bei bereits fertiggestellten und im freien Feld installierten Hochspannungsisolatoren, eine Überwachungseinrichtung nachzurüsten.However, all these known methods adhere to technically disadvantageous aspects that result from the use of optical waveguides for measured value transmission: To be able to provide the optical waveguides on or in the high-voltage insulator, a circumferential groove or whatever free cavity on or in High-voltage insulator can be created, which receives the one or more optical fibers. However, a mechanical change in the surface structure of the otherwise homogeneous surface of the high-voltage insulator or the provision of any kind of cavity is highly problematic from the perspective of dielectric strength and ultimately represents a potential defect for electric flashovers. Also, there are in the known methods no possibility to retrofit a monitoring device at a later date, that is, when already installed and installed in the open field high-voltage insulators.

Die DE 10 2006 053 986 A1 beschreibt einen Überspannungsableiter der einen Hochspannungsisolator mit einer Überwachungseinrichtung aufweist.The DE 10 2006 053 986 A1 describes a surge arrester having a high voltage insulator with a monitoring device.

Aufgabe der vorliegenden Erfindung ist es daher, einen Hochspannungsisolator aus Verbundwerkstoff anzugeben, der eine Möglichkeit zur Überwachung von technischen Parametern, wie Temperatur oder Druck, für das freie, mit Isoliergas befüllte, Innenvolumen vorsieht, ohne dabei in die homogene Oberflächenstruktur des Hochspannungsisolators mechanisch eingreifen oder einen offenen Kanal von innen nach außen durch die Wand des Isolators bohren zu müssen. Weiterhin ist es eine Aufgabe der Erfindung, eine technisch einfache Möglichkeit für eine nachrüstbare Überwachungseinrichtung an bereits vollständig gefertigten oder im freien Feld installierten Hochspannungsisolatoren bereit zu stellen.Object of the present invention is therefore to provide a high-voltage insulator made of composite material, which provides a way to monitor technical parameters, such as temperature or pressure, for the free, filled with insulating, internal volume without mechanically interfere with the homogeneous surface structure of the high-voltage insulator or to drill an open channel from the inside to the outside through the wall of the insulator. Furthermore, it is an object of the invention to provide a technically simple way for a retrofittable monitoring device to already fully manufactured or installed in the field high voltage insulators.

Diese Aufgabe wird durch einen Hochspannungsisolator mit den Merkmalen des ersten Patentanspruches gelöst. Die Unteransprüche betreffen dabei besonders vorteilhafte Weiterbildungen der Erfindung.This object is achieved by a high-voltage insulator having the features of the first claim. The subclaims relate to particularly advantageous developments of the invention.

Die allgemeine erfinderische Idee besteht darin, an der Innenseite des Isolierrohres einen Aufnehmer vorzusehen, der mit einem im Wesentlichen gegenüberliegend angeordneten Empfänger drahtlos korrespondiert. Unter Aufnehmer wird im Rahmen der Erfindung ein technisches Bauteil, insbesondere ein Sensor, verstanden, das bestimmte physikalische oder chemische Eigenschaften, beispielsweise Temperatur, Feuchtigkeit oder Druck, qualitativ oder als Messgröße auch quantitativ erfasst. Der Aufnehmer ist damit Teil einer Messeinrichtung, die auf eine Messgröße unmittelbar anspricht. Nach dem Wesen der Erfindung handelt es sich bei dem Aufnehmer um einen passiven Sensor, der in Hinblick auf die Erfassung der chemischen oder physikalischen Größen ohne externe Energieversorgung arbeitet und das erzeugte Messsignal drahtlos an den gegenüberliegend angeordneten Empfänger weiterleitet. Die Erzeugung des elektrischen Signals kann dabei insbesondere elektrodynamisch oder piezoelektrisch erfolgen. Unter passiven Sensoren werden im Rahmen der Erfindung auch so genannte AOW-Sensoren (Akustische Oberflächenwellen-Sensoren), auch als SAW-Sensoren bezeichnet (Surface Acustic Wave), verstanden. Sie sind für die Erfassung zahlreicher spannungsgebender physikalischer Größen anwendbar. Beschreibungen solcher AOW-Sensoren finden sich beispielsweise in den WO 96/33423 , WO 01/61859 und WO 01/91294 . Bisher jedoch ist noch nicht der Vorschlag gemacht oder der Versuch unternommen worden, solche bekannten Sensoren auf geeignete Weise in einem Hochspannungsisolator einzusetzen. Wird der ohne externe elektrische Energie arbeitende Aufnehmer erst einmal innerhalb des Isolierrohres des Hochspannungsisolators befestigt, so arbeitet dieser weiterstgehend autark. Der Aufnehmer kann dabei beispielsweise an der Innenseite des Isolierrohres aufgeklebt oder in sonstiger Weise fest mit der inneren Oberfläche des Isolierrohres verbunden werden.The general inventive idea is to provide on the inside of the insulating tube a transducer which corresponds wirelessly to a receiver arranged substantially opposite one another. In the context of the invention, a transducer is understood to be a technical component, in particular a sensor, which also quantitatively records specific physical or chemical properties, for example temperature, humidity or pressure, qualitatively or as a measured variable. The transducer is thus part of a measuring device that directly addresses a measurand. According to the essence of the invention, the sensor is a passive sensor which, with regard to the detection of the chemical or physical quantities, has no external Power supply operates and wirelessly transmits the generated measurement signal to the oppositely arranged receiver. The generation of the electrical signal can be effected in particular electrodynamically or piezoelectrically. Within the scope of the invention, passive sensors are also understood to be so-called SAW sensors (surface acoustic wave sensors), also referred to as SAW sensors (surface acoustic wave). They are applicable for the detection of numerous voltage-giving physical quantities. Descriptions of such AOW sensors can be found for example in the WO 96/33423 . WO 01/61859 and WO 01/91294 , So far, however, the proposal has not been made or attempted to use such known sensors in a suitable manner in a high-voltage insulator. If the transducer, which operates without external electrical energy, is first fastened inside the insulating tube of the high-voltage insulator, then it continues to operate independently. The transducer can be glued, for example, on the inside of the insulating tube or otherwise firmly connected to the inner surface of the insulating tube.

Durch die erfindungsgemäße Lösung können die aus glasfaserverstärktem Epoxidharz hergestellten Isolierrohre auf herkömmliche Weise gefertigt und mit einer Überwachungseinrichtung ausgestattet werden, ohne dabei eine umlaufende Nut oder einen wie auch immer gearteten freien Hohlraum am oder im Isolierrohr des Hochspannungsisolators vorsehen zu müssen.The solution according to the invention, the insulating tubes made of glass fiber reinforced epoxy resin can be manufactured in a conventional manner and equipped with a monitoring device, without having to provide a circumferential groove or any kind of free cavity on or in the insulating tube of the high-voltage insulator.

Nach einer vorteilhaften Weiterbildung der Erfindung sind der Aufnehmer und der im Wesentlichen gegenüberliegend angeordnete Empfänger im Bereich eines Flansches positioniert. Dies hat sich als vorteilhaft erwiesen, da die metallisch ausgebildeten Flansche eine elektromagnetisch abschirmende Wirkung haben und dadurch die auftretenden elektrischen Felder auf ein Minimum reduzieren.According to an advantageous embodiment of the invention, the pickup and the substantially oppositely arranged receiver are positioned in the region of a flange. This has proven to be advantageous because the metallic flanges have an electromagnetic shielding effect and thereby reduce the electrical fields occurring to a minimum.

Figur 1 zeigt einen nicht-erfindungsgemäßen Hochspannungsisolator 1 im vertikalen Querschnitt. Der Hochspannungsisolator 1 ist dabei vorzugsweise als hohler Verbundstoffisolator ausgebildet und umfasst ein im Wesentlichen rotationssymmetrisches Isolierrohr 2, welches in der Regel aus glasfaserverstärktem Epoxidharz besteht. An den Außenseiten des Isolierrohres 2 ist umfangsseitig eine wellenförmige Silikonbeschirmung 3 vorgesehen. An den jeweiligen Stirnseiten, d. h. den Anfangs- und Endstücken des Isolierohres 2, befinden sich formflüssig angeordnet, dieses am äußeren Umfang dichtend umgreifend, metallische Flansche 4 und 5, beispielsweise aus Aluminium. Gattungsgemäße Hochspannungsisolatoren 1, auch als Verbundisolatoren bezeichnet, werden am Markt beispielsweise unter dem Markennamen ReCoTec® von der Firma Reinhausen Power Composites GmbH vertrieben. Erfindungsgemäß werden nun derartige Hochspannungsisolatoren 1 um eine Überwachungseinrichtung, bestehend aus einem Aufnehmer 6 und einem Empfänger 7, erweitert. Der vorzugsweise als passiver Sensor ausgebildete Aufnehmer 6 ist dabei direkt an der inneren Mantelfläche des Isolierrohres 2 befestigt, insbesondere aufgeklebt und korrespondiert drahtlos mit dem Empfänger 7, der an der äußeren Mantelfläche der Silikonbeschirmung 3 befestigt ist. Der Empfänger 7 ist mittels einer Kabelverbindung 8 mit einer Messsignalauswerteeinrichtung 9 verbunden. FIG. 1 shows a non-inventive high voltage insulator 1 in vertical cross-section. The high-voltage insulator 1 is preferably formed as a hollow composite insulator and comprises a substantially rotationally symmetrical insulating tube 2, which is usually made of glass fiber reinforced epoxy resin. On the outer sides of the insulating tube 2 a wavy silicone screen 3 is circumferentially provided. At the respective end faces, ie the beginning and end pieces of the Isolierohres 2, are arranged form liquid, this sealingly encompassing the outer periphery, metallic flanges 4 and 5, for example made of aluminum. Generic high-voltage insulators 1, also referred to as composite insulators, are sold on the market, for example, under the brand name ReCoTec® by the company Reinhausen Power Composites GmbH. According to the invention, such high-voltage insulators 1 are now expanded by a monitoring device consisting of a pickup 6 and a receiver 7. The preferably designed as a passive sensor pickup 6 is attached directly to the inner surface of the insulating tube 2, in particular glued and corresponds wirelessly with the receiver 7, which is fixed to the outer surface of the silicone screen 3. The receiver 7 is connected by means of a cable connection 8 to a measuring signal evaluation device 9.

Im Unterschied zu Figur 1 ist in Figur 2 der Empfänger direkt an der äußeren Mantelfläche des Isolierrohres 2 angebracht und ebenfalls mittels einer Kabelverbindung 8 mit der Messsignalauswerteeinrichtung 9 verbunden.In contrast to FIG. 1 is in FIG. 2 the receiver is mounted directly on the outer surface of the insulating tube 2 and also connected by means of a cable connection 8 with the Meßsignalauswerteeinrichtung 9.

In Figur 3 ist eine bevorzugte Ausführungsform eines erfindungsgemäßen Hochspannungsisolators 1 schematisch dargestellt. Bei dieser Ausführungsform sind der Aufnehmer 6 und der im Wesentlichen gegenüberliegend angeordnete Empfänger 7 im Bereich des unteren Flansches 5 angeordnet. Ebenso wäre jedoch auch denkbar, Aufnehmer 6 und Empfänger 7 im Bereich des oberen Flansches 4 anzuordnen. Bei diesem Ausführungsbeispiel weist der untere Flansch 5 eine Ausnehmung 10 auf, innerhalb der der Empfänger 7 positioniert ist. Die Kabelverbindung 8 wird über eine in dem unteren Flansch 5 vorgesehene Bohrung 11 mit dem Empfänger 7 verbunden.In FIG. 3 a preferred embodiment of a high-voltage insulator 1 according to the invention is shown schematically. In this embodiment, the receiver 6 and the substantially oppositely arranged receiver 7 are arranged in the region of the lower flange 5. Likewise, however, it would also be conceivable to arrange pickup 6 and receiver 7 in the region of upper flange 4. In this embodiment, the lower flange 5 has a recess 10, within which the receiver 7 is positioned. The cable connection 8 is connected via a provided in the lower flange 5 bore 11 with the receiver 7.
