Description

Die Erfindung liegt auf dem Gebiet der grundlegenden elektrischen Bauteile und ist bei der konstruktiven Ausgestaltung eines Isolators anzuwenden, der mit einem Überspannungsableiter zu einer Baugruppe vereinigt ist.The invention is in the field of basic electrical components and is used in the structural design of an insulator, which is combined with a surge arrester to form an assembly.

Im Bereich der Energieübertragung und -verteilung werden als Überspannungsableiter in neuerer Zeit Metalloxid-Widerstände auf Zinkoxid-Basis mit stark nichtlinearer Charakteristik verwendet. Das relativ kleine Bauvolumen derartiger Ableiter eröffnet die Möglichkeit, solche Ableiter in Durchführungen, Kabelendverschlüssen und auch in das Innere von Transformatoren und Schaltanlagen zu integrieren (Z "Bulletin SEV/VSE", 7/98, Seiten 13 bis 20). Bei einer bekannten Integration eines derartigen Ableiters in eine Durchführung für einen Hochspannung führenden elektrischen Leiter sind die einzelnen, zu einer Säule aufgeschichteten Widerstandselemente des Ableiters innerhalb des Isolators konzentrisch zu dessen Achse und damit auch konzentrisch zu dem Hochspannung führenden Leiter angeordnet. Der Isolator besteht dabei aus einem hohl ausgebildeten und mit einer Beschirmung versehenen Gehäuse und weist ein metallenes Fußteil und ein metallenes Kopfteil auf. Die innerhalb des Gehäuses angeordneten Widerstandselemente des Ableiters bilden hierbei einzelne Abschnitte der Wandung eines hohlen Zylinders oder eines stumpfen Kegels. Dieser Zylinder oder Kegel ist auf seinem einen Ende auf Kontaktteile aufgesetzt, die radial durch die Wandung des Isolators nach außen geführt sind; an seinem anderen Ende ist der Zylinder bzw. der Kegel mit dem Hochspannung führenden Leiter verbunden (JP 59-207513A, JP 59-207514A). - Eine derartige Zuordnung des Überspannungsableiters zum Hochspannungsisolator erfordert im - auf Erdpotential liegendem - Fußbereich des Ableiters einen relativ großen Abstand zum auf Hochspannungspotential liegenden elektrischen Leiter und damit einen großen Durchmesser des Isolators wenigstens in dem Fußbereich. Die für die Kontaktierung des Ableiters erforderlichen Kontaktierungsvorrichtungen erhöhen ebenfalls das Volumen und auch die Komplexität der Baugruppe.In the field of energy transmission and distribution, metal oxide resistors based on zinc oxide with a highly nonlinear characteristic have recently been used as surge arresters. The relatively small volume of such arresters opens the possibility to integrate such arresters in bushings, cable terminations and also in the interior of transformers and switchgear (Z "Bulletin SEV / VSE", 7/98, pages 13 to 20). In a known integration of such a surge arrester in a passage for a high voltage leading electrical conductor, the individual, stacked to a column resistor elements of the arrester within the insulator concentric to the axis and thus concentric to the high voltage leading conductor are arranged. The insulator consists of a hollow formed and provided with a shielding housing and has a metal base and a metal headboard. The arranged inside the housing resistance elements of the arrester in this case form individual sections of the wall of a hollow cylinder or a blunt cone. This cylinder or cone is placed on its one end on contact parts, which are guided radially through the wall of the insulator to the outside; at its other end the cylinder or cone is connected to the high-voltage conducting conductor (JP 59-207513A, JP 59-207514A). Such an assignment of the surge arrester to the high-voltage insulator requires a relatively large distance to the electrical conductor lying at high voltage potential, and thus a large diameter of the insulator at least in the foot region, at the earth potential of the arrester. The contacting devices required for contacting the arrester also increase the volume and also the complexity of the assembly.

Zur Ausbildung eines leicht zu demontierenden und zu entsorgenden Überspannungsableiters ist es es bekannt, ein Gehäuse aus einem elastischen Material zu verwenden, welches zwei Ausnehmungen aufweist, in die unter Aufweitung des elastischen Gehäuses eine aus Metalloxid-Blöcken bestehende Ableitstrombahn sowie ein Tragelement einschiebbar sind. Das Tragelement dient der Gewährleistung einer ausreichenden mechanischen Stabilität der Anordnung (DE 43 19 986 A1).To form an easy to disassemble and dispose surge arrester, it is known to use a housing made of an elastic material having two recesses in the expansion of the elastic housing consisting of metal oxide blocks Ableitstrombahn and a support element can be inserted. The support element serves to ensure a sufficient mechanical stability of the arrangement (DE 43 19 986 A1).

Es ist weiterhin bekannt, einen Überspannungsableiter in einen Kabelendverschluss oder in einen hohlen, von einer Antriebsstange durchsetzten Isolierstoffstützer für einen Hochspannungs-Leistungsschalter zu integrieren (EP 0 388 779 B1, DE 196 47 736 C1). - Im Übrigen ist es zur Erzielung eines besonders kompakten leistungsstarken Überspannungsableiters bekannt, die Ableiterbahnen mehrsäulig auszuführen. Die Säulen sind dabei entlang einer Achse symmetrisch um diese angeordnet (Mayer, A; Rudolph, R.: Funkenstreckenlose Überspannungsableiter ermöglichen optimalen Überspannungsschutz. In: Brown Boveri Technik 12-85, S. 576-585).It is also known to integrate a surge arrester in a cable end closure or in a hollow, penetrated by a drive rod insulator for a high-voltage circuit breaker (EP 0 388 779 B1, DE 196 47 736 C1). - Incidentally, it is known to achieve a particularly compact powerful surge arrester, the Ableiterbahnen perform mehrsäulig. The pillars are arranged symmetrically about this axis along an axis (Mayer, A; Rudolph, R .: spark-gap-free surge arresters make optimum overvoltage protection possible. In: Brown Boveri Technik 12-85, pp. 576-585).

Ausgehend von einer Baugruppe mit den Merkmalen des Oberbegriffes des Patentanspruches 1 liegt der Erfindung die Aufgabe zugrunde, der Baugruppe einen einfachen Aufbau und dadurch eine kompaktere Bauweise zu geben.Starting from an assembly with the features of the preamble of claim 1, the invention has for its object to give the assembly a simple structure and thereby a more compact design.

Zur Lösung dieser Aufgabe ist gemäß der Erfindung vorgesehen, dass der Isolator aus einem hohlen Verbundkörper mit einem festen, ein elektrisches Bauteil umgebenden Korpus und einer auf den Korpus aufgegossenen oder aufgespritzten Umhüllung aus einem Elastomer besteht und dass der Überspannungsableiter in die auf den Korpus aufgegossene oder aufgespritzte Elastomerumhüllung eingebettet ist und mittels Anschlusselementen elektrisch an ein metallenes Fußteil und ein metallenes Kopfteil des Isolators angeschlossen ist. - Unter "hohler Verbundkörper" wird im Sinne der Erfindung auch ein um einen Leiter angeordneter Kunstharzisolierkörper (Durchführung) verstanden, insbesondere ein solcher, der für Spannungsebenen ab 6KV eingesetzt wird.To achieve this object, it is provided according to the invention that the insulator consists of a hollow composite body with a solid body surrounding an electrical component body and cast or sprayed onto the body casing of an elastomer and that the surge arrester infused into the body or on the is embedded and is connected by means of connecting elements electrically to a metal base part and a metal head part of the insulator. - "Hollow composite body" is understood in the context of the invention, a arranged around a conductor Kunstharzisolierkörper (implementation), in particular one which is used for voltage levels from 6KV.

Bei einer derartigen Ausgestaltung der Baugruppe ist der Überspannungsableiter nicht innerhalb des festen Korpus des Isolators angeordnet, sondern er wird dem Isolator außerhalb des festen Korpus zugeordnet. Durch die vorgesehene "back-up"-Zuordnung brauchen der Aufbau des festen Korpus und seine Abmessungen nicht verändert zu werden, während sich die Einbettung in die vergossene oder gespritzte Elastomerumhüllung des Verbundkörpers relativ einfach realisieren lässt. Dies gilt insbesondere dann, wenn als Widerstandselemente des Ableiters handelsübliche Standardelemente in Form massiver zylindrischer oder quaderförmiger Körper verwendet werden, die gegebenenfalls für Montagezwecke eine mittige Bohrung aufweisen können.- Verbundkörper mit einem festen Korpus aus einem glasfaserverstärkten Kunststoffrohr und mit einer gegossenen bzw. aufgespritzten Elastomerumhüllung sind für Hochspannungsisolatoren an sich gebräuchlich. Dabei ist dieElastomerumhüllung in aller Regel als Beschirmung ausgebildet (DE 197 38 338 A1; Weitgen, J.: Freiluftdurchführungen mit Silikonschirmen. In: etz Bd. 104 (1983) Heft 23, S. 12000-1205).In such an embodiment of the assembly of the surge arrester is not disposed within the solid body of the insulator, but it is assigned to the insulator outside of the fixed body. The intended "back-up" allocation of the structure of the solid body and its dimensions need not be changed, while the embedding in the molded or molded elastomer sheath of the composite can be relatively easily realized. This is especially true when standard elements in the form of solid cylindrical or cuboid body are used as resistance elements of the arrester, which may optionally have a central bore for mounting purposes.- composite body with a solid body made of a glass fiber reinforced plastic pipe and with a molded or sprayed elastomer sheath are used for high voltage insulators per se. In this case, the Elastomerumhüllung is usually designed as a shield (DE 197 38 338 A1; Weitgen, J .: outdoor bushings with silicone shades In: etz Bd. 104 (1983) Issue 23, pp 12000-1205).

Der in einen Verbundkörper integrierte Überspannungsableiter kann aus einer oder aus mehreren, beispielsweise zwei oder vier aus Widerstandselementen aufgebauten Ableitersäulen bestehen. Bei zwei Ableitersäulen empfiehlt es sich, die Säulen dicht benachbart zueinander oder diagonal zur Achse des Durchführungsisolators einander gegenüberliegend anzuordnen; bei drei oder mehr Ableitersäulen empfiehlt es sich, die Säulen in zwei Gruppen aufzuteilen und die beiden Säulengruppen diagonal zur Achse des Isolators einander gegenüberliegend anzuordnen. Vorzugsweise werden die Ableitersäulen spiegelbildlich zu einer die Achse des Isolators aufnehmenden Ebene angeordnet. In all diesen Fällen kann der mit der Aufdickung der Umhüllung des Isolators verbundene Mehrverbrauch an Elastomermaterial möglichst gering gehalten werden. Hierzu ist es zweckmäßig, wenn die äußere Kontur der Elastomerumhüllung an die äußere Kontur des festen Korpus und der Ableitersäule/n angepasst ist.The surge arrester integrated in a composite body can consist of one or more, for example two or four arrester columns constructed of resistance elements. For two arrester columns, it is advisable to arrange the columns closely adjacent to each other or diagonally opposite to the axis of the feedthrough insulator; in the case of three or more arrester columns, it is advisable to divide the columns into two groups and to arrange the two groups of columns diagonally to the axis of the insulator facing each other. Preferably, the arrester columns are arranged in mirror image to a plane receiving the axis of the insulator. In all these cases, the additional consumption of elastomeric material associated with the thickening of the sheath of the insulator can be minimized. For this purpose, it is expedient if the outer contour of the elastomer sheath is adapted to the outer contour of the solid body and the Ableitersäule / n.

Bei Baugruppen, die denen der Isolator mit einem metallenen Fußteil und einem metallenen Kopfteil versehen ist, kann die mit der Einbettung der Ableitersäulen in die aufgegossene oder aufgespritzte Elastomerumhüllung gegebene mechanische Halterung der Ableitersäulen dadurch verbessert werden, dass die zum elektrischen Anschluss der Ableitersäulen an das Fußteil und das Kopfteil des Isolators vorgesehenen Anschlusselemente als mechanische Tragorgane ausgebildet sind. Die Anschlusselemente können dabei die Form gestreckter Profilkörper oder schlanker Bolzen haben.For assemblies that the insulator is provided with a metal foot part and a metal head part, given by the embedding of the Ableitersäulen in the cast or sprayed elastomer sheath mechanical support of the Ableitersäulen can be improved by that for electrically connecting the Ableitersäulen to the foot and the head part of the insulator provided connection elements are designed as mechanical support members. The connection elements can have the shape of elongated profile body or slender bolts.

Der Isolator, in dessen Elastomerumhüllung der Überspannungsableiter integriert ist, kann mit seinem festen Korpus unterschiedlich genutzt sein. Bei Ausgestaltung als Hohlisolator kann der Innenraum ein elektrisches Bauteil wie eine Durchführung - mit oder ohne Kondensatorsteuerung -, ein mit einer Feldsteuerung oder einem Endverschluss versehenes Kabelende oder einen Spannungsteiler aufnehmen; er kann aber auch von einem mechanischen Bauteil wie einer Schaltstange durchsetzt sein und eine reine Stützerfunktion wahrnehmen.The insulator, in the elastomer sheath of the surge arrester is integrated, can be used differently with its solid body. When configured as a hollow insulator, the interior of an electrical component such as a implementation - with or without capacitor control - record a provided with a field control or an end closure cable end or a voltage divider; but it can also be penetrated by a mechanical component such as a shift rod and perform a pure support function.
