- solid insulation can concentrate all the mechanical stresses associated with thermal expansion, the use of solid insulators at low temperatures involves certain risks. This is one of the reasons why the standard IEC 60137: 2008 "Insulated bushings for alternating voltages above 1000V" limits the maximum excess of the temperature of the contact parts of an insulator above the ambient air temperature to a maximum of 65 ° C. At low ambient temperatures, such as B. in the far north, this makes operation more difficult and forces a possible reduction in reliability.

- the role of the geometric stabilizer is taken over by an Invar shell.
- Invar alloys, iron-nickel alloys with a nickel content of 30 to 40% with chromium, cobalt, copper, titanium or manganese doping are precision alloys with abnormally low coefficients of linear thermal expansion.

Abstract
Die Erfindung betrifft die Hochspannungstechnik, und zwar Hochspannungs-Einführungs- oder Durchführungsisolatoren. Die Erfindung zielt darauf ab, die Zuverlässigkeit von solchen Isolatoren zu erhöhen. Die Neuheit des Isolators besteht in der Verwendung eines geometrischen Stabilisators zur Kompensation der Wärmeausdehnung des Leiters. Die Rolle des geometrischen Stabilisators wird von einer Invar-Hülle übernommen. Invarlegierungen gehören zu Präzisionslegierungen mit minimalen linearen Wärmeausdehnungskoeffizienten. Die Invar-Hülle behält ihre stabilen Abmessungen, wenn sich thermische Verhältnisse des Isolators ändern. Dadurch kann der mechanische Einfluss auf die Isolierung so gering wie möglich gehalten werden. Außerdem können dadurch solche Schäden an der Isolierung wie Abblättern und Rissbildung vermieden werden. Der größte Effekt wird bei der Verwendung der Erfindung in Isolatoren mit RIP-Isolierung erreicht, die für den Einsatz in Gebieten mit kaltem Klima ausgelegt sind.The invention relates to high voltage engineering, namely high voltage lead-in or bushing insulators. The invention aims to increase the reliability of such isolators. The novelty of the insulator consists in the use of a geometric stabilizer to compensate for the thermal expansion of the conductor. The role of the geometric stabilizer is taken over by an Invar shell. Invar alloys are precision alloys with minimal linear thermal expansion coefficients. The Invar shell retains its stable dimensions when the thermal conditions of the insulator change. As a result, the mechanical influence on the insulation can be kept as low as possible. It can also prevent insulation damage such as peeling and cracking. The greatest effect is achieved when using the invention in insulators with RIP insulation, which are designed for use in areas with cold climates.
Description
Die Erfindung betrifft die Hochspannungstechnik, und zwar Hochspannungsisolatoren, die den Durchgang von Leitern durch eine Trennwand, z. B. eine Wand, das Gehäuse einer elektrischen Maschine oder eines elektrischen Geräts, gewährleisten und die Leiter davon isolieren. Die Erfindung zielt darauf ab, die Zuverlässigkeit von Isolatoren durch Verwendung eines geometrischen Stabilisators zu erhöhen. Die größte Wirkung erzielt die Erfindung bei der Verwendung in Isolatoren mit fester (trockener) Isolierung. Die feste (trockene) Isolierung besteht aus mit Harz imprägniertem Isolierpapier. Ebenfalls wirksam ist die Anwendung der Erfindung in Isolatoren, die für den Einsatz in Gebieten mit kaltem Klima ausgelegt sind.The invention relates to high voltage technology, namely high voltage insulators, which allow conductors to pass through a partition, e.g. B. ensure a wall, the housing of an electrical machine or an electrical device, and insulate the conductors therefrom. The invention aims to increase the reliability of isolators by using a geometric stabilizer. The invention achieves the greatest effect when used in insulators with solid (dry) insulation. The solid (dry) insulation consists of insulating paper impregnated with resin. The application of the invention is also effective in isolators designed for use in areas with cold climates.
Isolatoren mit Ölpapier-Isolierung (Isolierung mit ölgetränktem Papier, OIP-Isolierung) sorgen dafür, dass die Leiter durch die Trennwand geführt werden können und dabei gegen die Trennwand isoliert sind. Solche Isolatoren bilden den größten Teil der Hochspannungsisolatoren. Trotz aller positiven Eigenschaften solcher Isolatoren weisen sie eine Reihe von Mängeln auf. Diese Mängel beziehen sich vor allem auf die Kontrolle und Wartung der Isolatoren während des Betriebs. Zu den Mängeln der Isolatoren gehört auch Explosions- und Brandgefahr. Diese Mängel sind bei festen Isolatoren beseitigt worden. Hier handelt es sich um Isolatoren mit harzbeschichtetem Papier (RBP-Isolierung) oder mit harzimprägniertem Papier (RIP-Isolierung), die seit Ende des vorigen Jahrhunderts im Einsatz sind. Dabei kann eine bestimmte Art der Isolierung nicht als bevorzugt angesehen werden, da jede Art ihre eigenen positiven Eigenschaften hat. So bewährt sich die Ölpapier-Isolierung besser bei schwierigen klimatischen Arbeitsbedingungen mit großen Temperaturschwankungen der Umgebung. Die Ölimprägnierung des Papiers verleiht den Isolierschichten eine gewisse Beweglichkeit und verhindert eine mechanische Beanspruchung. Mechanische Spannungen können zu Rissen der Isolierung führen. Da eine feste Isolierung alle mechanischen Spannungen, die mit der Wärmeausdehnung verbunden sind, in sich konzentrieren kann, birgt die Verwendung von festen Isolatoren bei niedrigen Temperaturen gewisse Risiken. Dies ist einer der Gründe, warum die Norm IEC 60137:2008 "Insulated bushings for alternating voltages above 1000V" die maximale Überschreitung der Temperatur der Kontaktteile eines Isolators über die Umgebungslufttemperatur auf max. 65°C begrenzt. Bei niedrigen Umgebungstemperaturen, wie z. B. im hohen Norden, erschwert dies den Betrieb und zwingt zu einer möglichen Verringerung der Zuverlässigkeit.Insulators with oil paper insulation (insulation with oil-soaked paper, OIP insulation) ensure that the conductors can be guided through the partition wall and are insulated from the partition wall. Such isolators form the largest Part of the high voltage insulators. Despite all the positive properties of such insulators, they have a number of shortcomings. These shortcomings mainly relate to the inspection and maintenance of the isolators during operation. The deficiencies of the isolators also include the risk of explosion and fire. These deficiencies have been eliminated in solid insulators. These are insulators with resin-coated paper (RBP insulation) or with resin-impregnated paper (RIP insulation), which have been in use since the end of the last century. A certain type of insulation cannot be considered preferred, as each type has its own positive properties. Oil paper insulation is more effective in difficult climatic working conditions with large temperature fluctuations in the environment. The oil impregnation of the paper gives the insulating layers a certain mobility and prevents mechanical stress. Mechanical stresses can lead to cracks in the insulation. Since solid insulation can concentrate all the mechanical stresses associated with thermal expansion, the use of solid insulators at low temperatures involves certain risks. This is one of the reasons why the standard IEC 60137: 2008 "Insulated bushings for alternating voltages above 1000V" limits the maximum excess of the temperature of the contact parts of an insulator above the ambient air temperature to a maximum of 65 ° C. At low ambient temperatures, such as B. in the far north, this makes operation more difficult and forces a possible reduction in reliability.
So kann die technische Aufgabe, die Zuverlässigkeit von Isolatoren in einem weiten Bereich von Umgebungstemperaturänderungen zu erhöhen, auf eine Verringerung der durch Wärmeausdehnung verursachten mechanischen Spannungen im Isoliermaterial reduziert werden. Bei der Erfindung wird die Aufgabe dadurch gelöst, dass stromführende Elemente eines Isolators in eine Hülle aus Legierungen der Invargruppe (Eisen-Nickel-Legierung) eingebracht werden. Die Hülle nimmt die mit der Wärmeausdehnung des Leiters verbundenen Kräfte auf und schließt die Übertragung dieser Kräfte auf die Isolierung aus. Diese Lösung der Aufgabe der Erhöhung der Zuverlässigkeit unterscheidet die vorliegende Erfindung wesentlich von den bisher bekannten Lösungen, bei denen die Erhöhung der Zuverlässigkeit durch eine spezielle Isolierungsstruktur erreicht wird. Als Beispiel für einen Hochspannungsisolator kann das Patent
Zum Gegenstand der Erfindung gehört ein Hochspannungsisolator, der den Durchgang der Leiter durch die Trennwand ermöglicht und die Leiter von dieser Trennwand isoliert.

Die Rolle des geometrischen Stabilisators wird von einer Invar-Hülle übernommen. Invar-Legierungen, Eisen-Nickel-Legierungen mit einem Nickelgehalt von 30 bis 40 % mit Chrom-, Kobalt-, Kupfer-, Titan- oder Mangan-Dotierung sind Präzisionslegierungen mit anomal niedrigen linearen Wärmeausdehnungskoeffizienten. Der genaue Wert des linearen Ausdehnungskoeffizienten hängt von der Legierungszusammensetzung, den Härtungsverfahren und der Verfahren der mechanischen Bearbeitung ab. Die Invar-Hülle behält ihre stabilen Abmessungen, wenn sich thermische Verhältnisse des Isolators ändern. Dadurch wird der mechanische Einfluss auf die Isolierung so gering wie möglich gehalten.
