Abstract

The vacuum chamber has a cylindrical body (11) which at least partially consists of an insulating ceramic material, preferably AlO, glass or a similar material. It also has fixed contacts on a fixed contact rod (17) and a movable contact attached to a movable contact rod (22). The movable contacts are located in a vacuum inside the body (11) which is cast into an insulating material (30,31), in particular, a casting resin. The vacuum chamber is characterised by the fact that an elastic padding (34) is placed between the body (11) and the insulating material (30,31) to compensate relative displacements - which are brought about by temperature effects - of the body (11) and the insulating material.

Description

Die Erfindung betrifft eine Vakuumkammer gemäß dem Oberbegriff des Anspruches 1.The invention relates to a vacuum chamber according to the preamble of claim 1.

Eine Vakuumkammer der eingangs genannten Art besitzt einen zylinderförmigen Körper, in dem Vakuum herrscht und der ein bewegliches und ein festes Kontaktstück aufnimmt, wobei das feste Kontaktstück an einem feststehenden Kontaktstengel und das bewegliche Kontaktstück an einem beweglichen Kontaktstengel angeordnet sind, die vakuumdicht ins Innere des Körpers eingeführt sind. Die Vakuumkammer besitzt wenigstens einen zylindrischen Rohrabschnitt aus isolierendem Material, in bevorzugter Weise aus Keramik; der Körper ist an den beiden Enden mittels eines metallischen Deckels bzw. eines Faltenbalges vakuumdicht verschlossen, wobei der Faltenbalg die Bewegung des Kontaktstengels bzw. des beweglichen Kontaktstückes gestattet.A vacuum chamber of the type mentioned at the outset has a cylindrical body, there is a vacuum and there is a movable and a fixed contact piece takes up, the fixed contact piece on a fixed contact stem and the movable contact piece is arranged on a movable contact stem, which are inserted inside the body in a vacuum-tight manner. The vacuum chamber has at least one cylindrical tube section made of insulating material, more preferably Ceramic sage; the body is metallic at both ends Cover or a bellows closed vacuum-tight, the bellows Movement of the contact stem or the movable contact piece allowed.

B. auf der Isolierstrecke, d. h. auf der Außenseite des isolierenden Abschnittes des zylindrischen Körpers Fremdschichten bilden können, die die Spannungsfestigkeit herabsetzen.It is known to cover the vacuum chamber with a plastic, preferably epoxy resin encapsulate, see GB 1 030 798, around the surface of the insulating ceramic cylindrical tube section of the chamber from contamination protect because z. B. on the isolation path, d. H. on the outside of the insulating Section of the cylindrical body can form foreign layers that the Reduce dielectric strength.

Wenn der zylindrische Körper einer Vakuumkammer in Gießharz, z. B. Epoxidharz, eingegossen ist, dann besteht das Problem, daß sich bei gasisolierter Oberfläche eine mangelhafte Haftung zwischen dem Gießharz und der Keramik ergibt, was nur durch Zusatz eines Haftvermittlers behoben werden kann. Bei extremen Temperaturbelastungen können Risse im Gießharz auftreten, wodurch die Funktionstüchtigkeit der einzelnen eingegossenen Kammer teilweise oder gänzlich aufgehoben wird.If the cylindrical body of a vacuum chamber in resin, e.g. B. epoxy resin, is poured in, then there is the problem that there is a gas-insulated surface poor adhesion between the casting resin and the ceramic results in what only Addition of an adhesion promoter can be remedied. With extreme temperature loads cracks can occur in the casting resin, which reduces the functionality of the individual poured chamber is partially or completely canceled.

Aufgabe der Erfindung ist es, eine Vakuumkammer der eingangs genannten Art zu schaffen, bei der bei wirtschaftlicher Herstellung ein Reißen des Gießharzes aufgrund von Temperatureinflüssen vermieden wird.The object of the invention is to provide a vacuum chamber of the type mentioned create, in the case of economical production, a cracking of the casting resin of temperature influences is avoided.

B. temperaturbedingte Relativbewegungen zwischen dem zylindrischen Körper und dem Isoliermaterial ausgeglichen werden.According to the invention, there is therefore between the cylindrical body and the insulating material, d. H. the cast resin, an elastic padding through which z. B. temperature-related Relative movements between the cylindrical body and the insulating material be balanced.

Gemäß einer vorteilhaften Ausgestaltung der Erfindung kann die Polsterung aus Ethylen-Propylen-Dien- oder Ethylen-Prop-Ter-Kautschuk bestehen; sie ist in besonders vorteilhafter Weise durch einen Schlauch gebildet, der Mittel aufweist, mit denen der Schlauch zylindrisch gehalten ist, so daß er leicht über die Vakuumkammer geschoben werden kann; nach dem Überziehen werden die Mittel entfernt, so daß sich der Schlauch federnd - wie ein Schrumpfschlauch - um den zylindrischen Körper der Vakuumkammer herumlegt. Der Schlauch besitzt in dem Zustand, wenn die Mittel entfernt sind, einen deutlich kleineren Durchmesser als der zylindrische Körper.According to an advantageous embodiment of the invention, the padding can consist of ethylene-propylene-diene or ethylene-prop-ter rubber; she is special advantageously formed by a hose which has means with which the Hose is held cylindrical so that it can be easily pushed over the vacuum chamber can be; after coating, the agents are removed so that the Resilient tube - like a shrink tube - around the cylindrical body of the vacuum chamber laying around. The tube is in the state when the agent is removed are significantly smaller in diameter than the cylindrical body.

Als Material für die Polsterung kann auch Ethylen-Propylen-Mastics oder Polyethylen bzw. vernetztes Polyethylen benutzt werden.The material for the upholstery can also be ethylene-propylene mastics or polyethylene or cross-linked polyethylene can be used.

Dabei ist das Material des Schlauches so gewählt, daß es während des Eingusses der Schaltkammer den erhöhten Gießharztemperaturen widerstehen kann, ohne daß die Form oder die Eigenschaften verändert werden. Die Dicke der Polsterung, also des Schlauches, ist so zu wählen, daß sie während des Eingusses zum Abdichten der Gußform zum Formkern hin geeignet ist. Darüber hinaus ist das Material so zu wählen, daß es über einen Temperaturbereich von -30° C bis zu +105° C die unterschiedlichen Wärmekoeffizienten der Vakuumkammer ausgleicht und eine Rißbildung am Gießharz verhindert, d. h. die Polsterung muß die unterschiedlichen Wärmeausdehnungen des isolierenden Keramikabschnittes, Kupfer- und Stahlteile sowie des Gießharzes ausgleichen. Dieses wird mit dem im Patentanspruch 2 genannten Material erreicht.The material of the hose is chosen so that it is cast during the Switching chamber can withstand the elevated casting resin temperatures without the Shape or properties are changed. The thickness of the upholstery Hose, is to be chosen so that it seals during the pouring Mold to the mold core is suitable. In addition, the material is to be selected that the different over a temperature range of -30 ° C to + 105 ° C. Compensates for the heat coefficient of the vacuum chamber and cracking on the casting resin prevents d. H. the upholstery must accommodate the different thermal expansions of the equalize the insulating ceramic section, copper and steel parts and the casting resin. This is achieved with the material mentioned in claim 2.

Darüber hinaus geht die Polsterung eine gute Verbindung zum Gießharz ein und sie beeinflußt die Funktionseigenschaften der Schaltkammer nicht und verfügt weiterhin über ein gutes Eigenisoliervermögen.In addition, the upholstery forms a good bond with the resin and she does not affect the functional properties of the switching chamber and still has good self-insulation properties.

Dadurch, daß die Polsterung durch die Mittel eine Form erhält, die ein leichtes Überziehen über den zylindrischen Körper gestattet, ist die Montage der Polsterung sehr einfach.Because the upholstery is given a shape by the means that is easy to put on The installation of the upholstery is allowed via the cylindrical body simple.

Als elastisches Material kann auch Silikon bzw. Silikongummi verwendet werden.Silicone or silicone rubber can also be used as the elastic material.

In jedem Fall, insbesondere bei Silikongummi ist dafür zu sorgen, daß das elastische Material nicht vollständig in Gießharz eingebettet ist. In zweckmäßiger Weise ragt das elastische Material, insbesondere das Silikongummi an einem Ende der Vakuumkammer frei heraus, so daß sich das Material dort ausdehnen kann. In any case, especially with silicone rubber, care must be taken that the elastic Material is not completely embedded in cast resin. This juts out in a practical way elastic material, especially the silicone rubber at one end of the vacuum chamber out freely so that the material can expand there.

At the end protruding from the vacuum chamber 10, a contact connection 18 is connected perpendicular to the central axis MM of the vacuum chamber 10, to which an upper feed line can be fastened by means of a screw connection 19.

    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, bottom end 20 of the lower insulating section 13 is connected to a cylindrical metallic pipe section 21, which is of a movable Contact stem 22 is penetrated, between in a manner not shown the movable contact stem 22 and the metallic portion 21 Bellows is arranged, the movement of the movable contact stem 22 in Direction of the central axis M-M permitted; at the inner end of the movable contact stem 22 there is a movable contact piece, which with the fixed Contact piece forms a contact point. At the outer end of the contact stem 22 connects a flexible band 23, which is connected to a contact terminal 24 is connected to a lower feed line by means of a screw connection 25 can be. The contact stem 22 is connected to a drive rod 26.

    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 vacuum chamber 10 is, as can be seen from the FIG., In a cast resin insulation 30 cast in, which has a section 31 which surrounds the cylindrical body 11, the insulating body 30, 31 also enclosing the cover 16 and the contact connection 18. At the front end of the body 11 of the vacuum chamber 10, from which the movable Contact stem 22 protrudes, a section adjoins section 31 Collar 32 on the one hand encloses the contact terminal 24 and on its outer surface has circumferential projections 33 which increase the insulation strength serve with regard to leakage currents. The cylindrical collar partially surrounds the drive rod 26.

    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 section 31 of the insulating body and the outer surface of the cylindrical body 11 there is a padding 34 which covers the two end faces of the cylindrical body 11 except for the area of the contact stem 17 and the Contact stem 22 surrounds.

    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 cylindrical body 11 of the vacuum chamber can. After removing the plastic spiral, the hose is inserted similarly Shrink tubing against the outer surface of the body 11, the relaxing of the hose takes place evenly, so that there is between the body 11 and the End faces, ie the switching chamber 10 does not form an air cushion. The length of the hose is chosen so that subsequent processing, eg. B. shortening the Hose, is no longer required. The preheated, padded vacuum chamber is then used in the automatic pressure gelling process with aromatic or cycloaliphatic, Pour filled epoxy resins, the sealing of the mold to Mold core takes over the padding 34.

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 padding 34 is the upper and lower end faces of the vacuum chamber 21 partially covered. The padding 34 protrudes on the lower end face from the space 40 between the vacuum chamber 21 and the casting resin 31 a free end 41 out. That the padding 34 partially covers the lower end face 42 covered is of lesser importance. It is essential that the padding 34 there not, as is completely enclosed by the casting resin on the upper end face 43, but protrudes freely, so that a free expansion downwards is possible. Especially with silicone rubber as padding 34, the free expansion possibility is necessary and advantageous to achieve sufficient elastic cushioning effects.
