Anhand der Zeichnung, in der ein Ausführungsbeispiel der Erfindung dargestellt ist,
sollen die Erfindung sowie weitere vorteilhafte Ausgestaltungen und Verbesserungen
der Erfindung näher erläutert und beschrieben werden.
Eine Vakuumkammer 10 besitzt einen zylindrischen Körper 11, der zwei zylindrische
Rohrabschnitte 12, 13 aus isolierender Keramik, vorzugsweise aus Al2O3, umfaßt, die
unter Zwischenfügung eines metallischen Ringes 14 miteinander verbunden sind. Der
metallische Ring dient dazu, einen im Inneren der Vakuumkammer 10 befindlichen
Schirm zu halten. Die in der Zeichnung oben liegende Stirnkante 15 des zylindrischen
Körpers 11 ist mit einem Metalldeckel 16 abgedeckt, der von einem feststehenden
Kontaktstengel 17 durchdrungen ist, das an seinem inneren Ende ein nicht dargestelltes
feststehendes Kontaktstück trägt. An dem aus der Vakuumkammer 10 herausragenden
Ende ist senkrecht zur Mittelachse M-M der Vakuumkammer 10 ein Kontaktanschluß
18 angeschlossen, an dem eine obere Zuleitung mittels einer Schraubenverbindung
19 befestigbar ist.A
Das andere, unten befindliche Stirnende 20 des unteren isolierenden Abschnittes 13 ist
mit einem zylindrischen metallischen Rohrstück 21 verbunden, das von einem beweglichen
Kontaktstengel 22 durchgriffen ist, wobei in nicht näher dargestellter Weise zwischen
dem beweglichen Kontaktstengel 22 und dem metallischen Abschnitt 21 ein
Faltenbalg angeordnet ist, der die Bewegung des beweglichen Kontaktstengels 22 in
Richtung der Mittelachse M-M gestattet; am inneren Ende des beweglichen Kontaktstengels
22 befindet sich ein bewegliches Kontaktstück, das mit dem feststehenden
Kontaktstück eine Kontaktstelle bildet. An dem äußeren Ende des Kontaktstengels 22
schließt ein flexibles Band 23 an, welches mit einem Kontaktanschluß 24 verbunden
ist, an dem eine untere Zuleitung mittels einer Schraubverbindung 25 angeschlossen
werden kann. Der Kontaktstengel 22 ist mit einer Antriebsstange 26 verbunden.The other,
Die Vakuumkammer 10 ist, wie aus der Fig. ersichtlich, in eine Gießharzisolierung 30
eingegossen, die einen Abschnitt 31 aufweist, der den zylindrischen Körper 11 umgibt,
wobei der Isolierkörper 30, 31 auch den Deckel 16 sowie den Kontaktanschluß 18 umschließt.
An dem Stirnende des Körpers 11 der Vakuumkammer 10, aus dem der bewegliche
Kontaktstengel 22 herausragt, schließt an den Abschnitt 31 ein zylindrischer
Kragen 32 an, der einerseits den Kontaktanschluß 24 umschließt und an seiner Außenfläche
umlaufende Vorsprünge 33 aufweist, die zur Erhöhung der Isolierfestigkeit
bezüglich Kriechströme dienen. Der zylindrische Kragen umgibt teilweise die Antriebsstange
26.The
Diese einzelnen Merkmale sind an sich bekannt, siehe beispielsweise die GB 1 030 798.These individual features are known per se, see for example GB 1 030 798.
Zwischen der Innenseite des Abschnittes 31 des Isolierkörpers und der Außenfläche
des zylindrischen Körpers 11 befindet sich eine Polsterung 34, die die beiden Stirnflächen
des zylindrischen Körpers 11 bis auf den Bereich des Kontaktstengels 17 und des
Kontaktstengels 22 umgibt.Between the inside of
Die Polsterung besteht aus einem Ethylen-Propylen-Dien-Kautschukschlauch, der mittels
einer Kunststoffspirale in einer zylindrischen Form gehalten ist, so daß der
Schlauch über den zylindrischen Körper 11 der Vakuumkammer geschoben werden
kann. Nach Entfernung der Kunststoffspirale legt sich der Schlauch ähnlich wie ein
Schrumpfschlauch gegen die Außenfläche des Körpers 11 an, wobei das Entspannen
des Schlauches gleichmäßig erfolgt, so daß sich zwischen dem Körper 11 und den
Stirnflächen, also der Schaltkammer 10 kein Luftpolster bildet. Die Länge des Schlauches
ist dabei so gewählt, daß eine nachträgliche Bearbeitung, z. B. ein Kürzen des
Schlauches, nicht mehr erforderlich ist. Die vorgeheizte, gepolsterte Vakuumkammer
wird dann im automatischen Druckgelierverfahren mit aromatischen oder zycloaliphatischen,
gefüllten Epoxidharzen umgossen, wobei die Abdichtung der Gußform zum
Formkern die Polsterung 34 übernimmt.The padding consists of an ethylene-propylene-diene rubber hose, which means
a plastic spiral is held in a cylindrical shape so that the
Hose are pushed over the

Die Zeichnung zeigt, daß die Polsterung 34 die obere und untere Stirnfläche der Vakuumkammer
21 teilweise überdeckt. An der unteren Stirnfläche ragt die Polsterung 34
aus dem Zwischenraum 40 zwischen der Vakuumkammer 21 und dem Gießharz 31 mit
einem freien Ende 41 heraus. Daß die Polsterung 34 die untere Stirnfläche 42 teilweise
überdeckt, ist von geringerer Bedeutung. Wesentlich ist, daß die Polsterung 34 dort
nicht, wie an der oberen Stirnfläche 43, vollständig vom Gießharz umschlossen ist,
sondern frei herausragt, so daß eine freie Ausdehnung nach unten möglich ist. Insbesondere
bei Silikongummi als Polsterung 34 ist die freie Ausdehnungsmöglichkeit notwendig
und vorteilhaft, um ausreichende elastische Polsterungswirkungen zu erzielen.The drawing shows that the
