Abstract: Der Hochspannungsisolator enthält eine Metallarmatur (2), ein mit der Metallarmatur verfugtes Isolierrohr (1), welches an einem als Tragring (10) ausgebildeten Ende mit der Metallarmatur verklebt ist, und eine um die Achse (A) des Isolierrohrs geführte, axialsymmetrische Klebfuge. In die Metallarmatur ist eine um die Achse des Isolierrohrs geführte, ringförmige Nut (23) eingeformt, welche einen Endabschnitt des Tragrings aufnimmt. In die Nut (23) und in den Tragring (10) ist jeweils eine Dichtungsfläche (24, 13) eingeformt. Die beiden Dichtungsflächen sind derart angeordnet und ausgebildet, dass sie beim Verfugen von Isolierrohr (1) und Metallarmatur (2) unter Bildung einer Dichtung aufeinander gleiten und der als Verdrängungskörper wirkende Tragring (10) vor dem Verfugen in die Nut (23) eingebrachten Klebstoff (32) in die Klebfuge presst. Der Isolator und ein diesen Isolator enthaltendes Kühlelement sind einfach zu fertigen und zeichnen sich durch eine Leckrate von weniger als 10 -9 [bar l/s] aus sowie durch grosse Betriebssicherheit auch nach langjährigem Betrieb unter starker mechanischer, elektrischer, thermischer und chemischer Belastung.
Abstract translation: 高电压绝缘体包括金属配件（2），与金属配件绝缘管一verfugtes（1），其形成在一个作为支撑环（10）端部到金属配件接合，以及关于绝缘管的引导的轴线（A），轴对称接合接头。 在围绕所述绝缘管被引导环形槽的轴的金属配件（23）形成，其接收所述支撑环的端部。 在凹槽（23）和在所述支撑环（10）每个都具有被形成（24，13）的密封表面。 两个密封面被布置和构造成使得它们在焊接绝缘管滑动（1）和金属配件（2），以形成具有彼此密封并用作在沟槽中灌浆之前的位移体支撑环（10）（23）引入的粘合剂（ 32）压入到胶接接头。 绝缘体和含有冷却元件该绝缘体是易于制造并且即使在严重的机械，电，热和化学应力下多年的运作是由小于10-9 [巴升/秒]，以及通过大的运行可靠性的泄漏速率表征。

Abstract: The high-voltage insulator contains a metal armature (2), an insulating tube (1) which is joined to the metal armature and is adhesively bonded to the metal armature at an end in the form of a bearing ring (10), and an axially symmetrical adhesive-bonding joint which is guided around the axis (A) of the insulating tube. An annular groove (23) which is guided around the axis of the insulating tube and receives an end section of the bearing ring is formed in the metal armature. A respective sealing surface (24, 13) is formed in the groove (23) and in the bearing ring (10). The two sealing surfaces are arranged and formed in such a manner that they slide on one another when joining the insulating tube (1) and the metal armature (2) so as to form a seal, and the bearing ring (10) which acts as a displacement body presses adhesive (32), which has been introduced into the groove (23), into the adhesive-bonding joint before joining. The insulator and a cooling element containing this insulator are simple to produce and are distinguished by a leakage rate of less than 10
-9 [bar l/s] and by great operational reliability even after many years of operation with a large mechanical, electrical, thermal and chemical load.-
