Definitions
- the invention relates to a contact arrangement for step selector according to the preamble of claim 1.
- Such contact arrangements are known: DE-AS 11 18 860.
- insulating material cylinders manufactured using the filament process are used both for the diverter switch and for the tap selector. It is therefore necessary to arrange a large number of contact pieces in the wall of such an insulating material cylinder. It should be taken into account here that the shaft seated in the wall of the insulating material cylinder acts as an electrode, on which high exit field strengths occur, mainly when subjected to electrical shock. The contact pieces sitting in the wall are therefore provided with additional cross insulation. This is to prevent the high exit field strengths that occur from coming to rest directly on the glass fibers cut through with the bore and on the capillaries that may form around individual filaments. Since it is also important to avoid metallic fasteners when fastening the contact pieces, so as not to further reduce the electrical strength between the contacts by means of these metallic fasteners, the contact arrangements mentioned are very expensive.
- the object of the invention is to provide a contact arrangement according to the preamble of claim 1, which can be produced in a simple manner while avoiding metallic fastening means which would lead to a deterioration in the field profile and which therefore require additional control electrodes leaves. This object is achieved by the means specified in the characterizing part of claim 1.
- the new contact arrangement can be produced with simple tools or aids
- another advantage is that the contact piece can be fastened in the cylinder wall without additional metallic parts and also without sharp-edged threads.
- the insulating-material socket lying on the side of the terminal lug is provided with two opposing cutouts corresponding to the width of the terminal lug. This simplifies the assembly of the contact device, since the insulating bush can also be pushed onto the shaft after the terminal lug has been crimped, after which it is then rotated through 90 °.
- the shaft of the contact piece in the region of the two insulating material sockets with a thin layer of dielectric high-quality insulating material.
- the shaft can e.g. can be wrapped with a special insulating material or it can e.g. be coated with insulating material using the fluidized bed process.
- the contact is easily possible to arrange the contact to be provided with a usual shielding electrode on the connection side.
- This can be arranged in such a way that it is simply clamped between the insulating material bushing and the deforming point, whereby it lies against the surface of the insulating material bushing.
- the insulating material bushing can furthermore be provided with a peripheral edge which surrounds the shielding electrode on the outside and which forms a further insulating barrier.
- the contact piece with a flat shaft 1 is inserted into the wall 2 of an insulating material cylinder.
- the contact piece has a contact surface designed as an electrode shape 3 on the inside of the cylinder and a connection surface designed as a flat connection 4 on the outside.
- the contact piece with its contact surface designed as an electrode shape 3, is firmly embedded in the insulating sleeve 5 and, on the other hand, through deformations 9, which have been made on the outside of the wall 2 on the shaft 1 and which are directed against the outer insulating sleeve 6, in the wall 2 of the Insulated plastic cylinder held.
- the gap 11 existing between the two insulating material bushings 5, 6 is connected to the outside via ventilation ducts 12.
- the two recognizable bores 13 serve to deform the shaft 1 on the outside of the wall 2 of the insulating material cylinder.
- the contact piece has a round shaft 31, which in turn is seated in the wall 2 of an insulating material cylinder.
- the inner, thicker end 33 forming the contact surface is again designed as an electrode shape and lies firmly against the inner insulating material bush 35.
- the outer end of the contact piece is provided with a crimped flat connection 34, the flat connection extending beyond the width of the shaft 31.
- the outer insulating material bushing 36 has two cutouts 361, which correspond to the width of the flat connection 34.
- the outer insulating material bushing 36 can subsequently be pushed over the flat connection and then subsequently rotated by approximately 90 °.
- the contact piece is fixed by deformations 39 which have been made on the shaft 31 on the outside of the wall 2 in such a way that the contact piece together with the two insulating material bushings 35, 36 is held firmly in the wall 2 of the insulating material cylinder becomes. Vent channels 312 are also provided here.
- FIGS. 4a and 4b show an embodiment as has already been shown and described in FIGS. 1, 2a and 2b.
- the shaft 41 of the contact piece in the area of the two insulating bushings 45, 46 is provided with additional insulation 14 made of high-quality insulating material. Everything else corresponds to the example described above.
- the exemplary embodiment described at the outset is provided with an additional shielding electrode 15, which is arranged around the deformations 9.
- the shielding electrode 15 lies against the surface of the outer insulating bush 6 and is also held by the deformations 9.
- the outer insulating material bushing 66 is provided with a peripheral edge 16 which surrounds the shielding electrode 15 laterally and is open to the outside. This edge 16 serves as an additional insulating barrier. All other features correspond to the features described with reference to FIGS. 1, 2a, 2b.

Abstract
Description
Die Erfindung bezieht sich auf eine Kontaktanordnung für Stufenwähler gemäß Oberbegriff des Patentanspruches 1. Derartige Kontaktanordnungen sind bekannt: DE-AS 11 18 860.The invention relates to a contact arrangement for step selector according to the preamble of
Bei Stufenschaltern für Stufentransformatoren werden im Filament-Verfahren hergestellte Isolierstoffzylinder sowohl für den Lastumschalter wie auch für den Stufenwähler verwendet. Es ist deshalb erforderlich, eine Vielzahl von Kontaktstücken in der Wand eines derartigen Isolierstoffzylinders anzuordnen. Hierbei ist zu berücksichtigen, daß der in der Wand des Isolierstoffzylinders sitzende Schaft als Elektrode wirkt, an der, hauptsächlich bei elektrischer Stoßbeanspruchung, hohe Austrittsfeldstärken auftreten. Es werden deshalb die in der Wand sitzenden Kontaktstücke mit einer zusätzlichen Querisolation versehen. Hiermit soll verhindert werden, daß die auftretenden hohen Austrittsfeldstärken direkt an den mit der Bohrung durchtrennten Glasfasern und den sich eventuell um einzelne Filaments bildenden Kapillaren zu liegen kommen. Da es ferner noch darauf ankommt, bei der Befestigung der Kontaktstücke metallische Befestigungsmittel möglichst zu vermeiden, um nicht die elektrische Festigkeit zwischen den Kontakten durch diese metallischen Befestigungsmittel zusätzlich herabzusetzen, gestalten sich die genannten Kontaktanordnungen sehr aufwendig.In the case of tap changers for tap transformers, insulating material cylinders manufactured using the filament process are used both for the diverter switch and for the tap selector. It is therefore necessary to arrange a large number of contact pieces in the wall of such an insulating material cylinder. It should be taken into account here that the shaft seated in the wall of the insulating material cylinder acts as an electrode, on which high exit field strengths occur, mainly when subjected to electrical shock. The contact pieces sitting in the wall are therefore provided with additional cross insulation. This is to prevent the high exit field strengths that occur from coming to rest directly on the glass fibers cut through with the bore and on the capillaries that may form around individual filaments. Since it is also important to avoid metallic fasteners when fastening the contact pieces, so as not to further reduce the electrical strength between the contacts by means of these metallic fasteners, the contact arrangements mentioned are very expensive.
Aufgabe der Erfidung ist es, eine Kontaktanordnung gemäß Oberbegriff des Patentanspruches 1 anzugeben, die sich auf einfache Weise unter Vermeidung metallischer Befestigungsmittel, die zu einer Verschlechterung des Feldverlaufs führen würden und die damit zusätzlicher Steuerelektroden bedürfen, herstellen läßt. Diese Aufgabe wird durch die im Kennzeichen des Anspruches 1 angegebenen Mittel gelöst.The object of the invention is to provide a contact arrangement according to the preamble of
Neben der Tatsache, daß die neue Kontaktanordnung mit einfachen Werkzeugen oder Hilfsmitteln herstellbar ist, fällt als weiterer Vorteil ins Gewicht, daß die Befestigung des Kontaktstückes in der Zylinderwand ohne zusätzliche metallische Teile und auch ohne scharfkantige Gewinde erfolgen kann.In addition to the fact that the new contact arrangement can be produced with simple tools or aids, another advantage is that the contact piece can be fastened in the cylinder wall without additional metallic parts and also without sharp-edged threads.
Da beim Zusammenschieben der beiden buchsenartigen Isolierstoffteile ein Spalt zwischen beiden Isolierstoffbuchsen verbleibt, werden zweckmäßigerweise Entlüftungskanäle, die den Spalt mit dem Außenraum verbinden, vorgesehen. Es wird so vermieden, daß beim Einsetzen des Stufenwählers in den Ölraum des Transformators Luftpolster am Kontaktstück bleiben.Since a gap remains between the two insulating material bushes when the two bushing-like insulating material parts are pushed together, ventilation channels which connect the gap to the outside space are expediently provided. It is thus avoided that air cushions remain on the contact piece when the tap selector is inserted into the oil space of the transformer.
Bei einem Kontaktstück mit rundem Schaft und angequetschter Anschlußfahne ist es von Vorteil, wenn die auf der Seite der Anschlußfahne liegende Isolierstoffbuchse mit zwei sich gegenüberliegenden Aussparungen entsprechend der Breite der Anschlußfahne versehen wird. Dies erleichtert die Montage der Kontaktvorrichtung, da die Isolierstoffbuchse auch nach dem Anquetschen der Anschlußfahne auf den Schaft geschoben werden kann, wonach sie dann um 90° verdreht wird.In the case of a contact piece with a round shaft and a crimped terminal lug, it is advantageous if the insulating-material socket lying on the side of the terminal lug is provided with two opposing cutouts corresponding to the width of the terminal lug. This simplifies the assembly of the contact device, since the insulating bush can also be pushed onto the shaft after the terminal lug has been crimped, after which it is then rotated through 90 °.
Bei spannungsmäßig besonders hoch beanspruchten Kontaktvorrichtungen kann es zweckmäßig sein, den Schaft des Kontaktstückes im Bereich der beiden Isolierstoffbuchsen mit einer dünnen Schicht aus dielektrisch hochwertigem Isoliermaterial zu versehen. Der Schaft kann hierbei z.B. mit einem speziellen Isolierstoff umwickelt werden oder er kann auch z.B. im Wirbelsinterverfahren mit Isolierstoff beschichtet werden.In the case of contact devices which are particularly stressed in terms of voltage, it may be expedient to provide the shaft of the contact piece in the region of the two insulating material sockets with a thin layer of dielectric high-quality insulating material. The shaft can e.g. can be wrapped with a special insulating material or it can e.g. be coated with insulating material using the fluidized bed process.
Ferner ist es ohne weiteres möglich, die Kontaktanordnung auf der Anschlußseite mit einer üblichen Abschirmelektrode zu versehen. Diese kann so angeordnet werden, daß sie zwischen Isolierstoffbuchse und Verformstelle einfach eingeklemmt wird, wobei sie an der Oberfläche der Isolierstoffbuchse anliegt. Hierbei kann ferner die Isolierstoffbuchse mit einem umlaufenden, die Abschirmelektrode seitlich umgreifenden nach außen offenen Rand, der eine weitere Isolierbarriere bildet, versehen werden.Furthermore, it is easily possible to arrange the contact to be provided with a usual shielding electrode on the connection side. This can be arranged in such a way that it is simply clamped between the insulating material bushing and the deforming point, whereby it lies against the surface of the insulating material bushing. In this case, the insulating material bushing can furthermore be provided with a peripheral edge which surrounds the shielding electrode on the outside and which forms a further insulating barrier.

Wie aus den Figuren 1, 2a und 2b hervorgeht, steckt das Kontaktstück mit einem flach ausgebildeten Schaft 1 in der Wand 2 eines Isolierstoffzylinders. Das Kontaktstück besitzt auf der Innenseite des Zylinders eine als Elektrodenform 3 gestaltete Kontaktfläche sowie auf der Außenseite eine als Flachanschluß 4 ausgebildete Anschlußfläche. Um den Schaft 1 herum sind zwei Isolierstoffbuchsen 5, 6 angeordnet, die ineinandergreifen, wobei die innere Isolierstoffbuchse 5 mit einem Rand 7 an der Innenseite der Wand 2 und die äußere Isolierstoffbuchse 6 mit einem Rand 8 an der Außenseite der Wand 2 anliegen. Das Kontaktstück ist mit seiner als Elektrodenform 3 gestalteten Kontaktfläche fest in die Isolierstoffbuchse 5 eingebettet und andererseits durch Verformungen 9, die an der Außenseite der Wand 2 am Schaft 1 vorgenommen worden sind und die gegen die äußere Isolierstoffbuchse 6 gerichtet sind, in der Wand 2 des Isolierstoffzylinders gehalten. Der zwischen den beiden Isolierstoffbuchsen 5, 6 bestehende Spalt 11 steht über Entlüftungskanäle 12 mit dem Außenraum in Verbindung. Die beiden erkennbaren Bohrungen 13 dienen der Verformung des Schaftes 1 auf der Außenseite der Wand 2 des Isolierstoffzylinders. In diese Bohrungen greift bei der Montage der Kontaktvorrichtung ein geeignetes, nicht dargestelltes Werkzeug ein, mit welchem die Verformung vorgenommen wird.As can be seen from FIGS. 1, 2a and 2b, the contact piece with a
Gemäß Figur 3a und 3b besitzt das Kontaktstück einen runden Schaft 31, der wiederum in der Wand 2 eines Isolierstoffzylinders sitzt. Das die Kontaktfläche bildende innere, dicker ausgeführte Ende 33 ist wiederum als Elektrodenform ausgebildet und liegt fest an der inneren Isolierstoffbuchse 35 an. Das äußere Ende des Kontaktstückes ist mit einem angequetschten Flachanschluß 34 versehen, wobei der Flachanschluß über die Breite des Schafts 31 hinausreicht. Dementsprechend besitzt die äußere Isolierstoffbuchse 36 zwei Aussparungen 361, die der Breite des Flachanschlusses 34 entsprechen. Wurde die innere Isolierstoffbuchse 35 bereits vor dem Anquetschvorgang des Flachanschlusses 34 auf das Kontaktstück aufgesteckt, so kann die äußere Isolierstoffbuchse 36 nachträglich über den Flachanschluß geschoben und dann anschließend um etwa 90° verdreht werden. Auch hier erfolgt das Festlegen des Kontaktstückes durch Verformungen 39, die am Schaft 31 auf der Außenseite der Wand 2 vorgenommen worden sind, derart, daß das Kontaktstück zusammen mit den beiden Isolierstoffbuchsen 35, 36 fest in der Wand 2 des Isolierstoffzylinders gehalten wird. Auch hier sind Entlüftungskanäle 312 vorgesehen.According to FIGS. 3a and 3b, the contact piece has a

Alles übrige entspricht dem zuvor beschriebenen Beispiel.FIGS. 4a and 4b show an embodiment as has already been shown and described in FIGS. 1, 2a and 2b. Here, however, the
Gemäß Figur 5a und 5b ist das eingangs beschriebene Ausführungsbeispiel mit einer zusätzlichen Abschirmelektrode 15 versehen, welche um die Verformungen 9 herum angeordnet ist. Die Abschirmelektrode 15 liegt dabei an der Oberfläche der äußeren Isolierstoffbuchse 6 an und wird ebenfalls durch die Verformungen 9 gehalten.According to FIGS. 5a and 5b, the exemplary embodiment described at the outset is provided with an
Gemäß Figur 6a und 6b, die im wesentlichen wiederum eine Ausführung, wie zuvor in Figur 1, 2a und 2b beschrieben, zeigt, ist die äußere Isolierstoffbuchse 66 mit einem umlaufenden Rand 16 versehen, der die Abschirmelektrode 15 seitlich umgreift und nach außen offen ist. Dieser Rand 16 dient als zusätzliche Isolierbarriere. Alle übrigen Merkmale stimmen mit den an Hand der Figuren 1, 2a, 2b beschriebenen Merkmalen überein.According to FIGS. 6a and 6b, which again essentially shows an embodiment as previously described in FIGS. 1, 2a and 2b, the outer insulating
