Description

Die vorliegende Erfindung betrifft eine Haltevorrichtung zum Halten einer Schaltröhre in einem Tragrahmen eines Schalterpols mit einem eine Durchgangsöffnung aufweisenden Halteabschnitt, der zum Anliegen an einer Stirnfläche der Schaltröhre eingerichtet ist, einem mit dem Halteabschnitt fest verbundenen Flanschabschnitt, der die Außenkontur der Stirnfläche zumindest teilweise umschließt, und einer Tragrahmenbefestigung zur Montage der Haltevorrichtung an dem Tragrahmen.The present invention relates to a holding device for holding a switch tube in a support frame of a switch pole having a through-opening having a holding portion which is adapted to abut on an end face of the interrupter, a fixedly connected to the holding portion flange portion which surrounds the outer contour of the end face at least partially, and a support frame attachment for mounting the holding device to the support frame.

Eine solche Haltevorrichtung ist aus der US 2001/0025829 A1 bereits bekannt. Die vorbekannte Haltevorrichtung ist zum Halten einer Vakuumschaltröhre eingerichtet und weist einen kreisplattenförmigen Halteabschnitt auf, der im Betrieb an einer Stirnseite einer Vakuumschaltröhre anliegt, durch die sich eine in einer Längsrichtung bewegliche Schaltstange erstreckt. Der Halteabschnitt ist mit einem sich im Wesentlichen rechtwinklig zu diesem erstreckenden Halteabschnitt verbunden, der sich in einer eingebauten Stellung um die Kontur der eingesetzten Vakuumschaltröhre erstreckt und somit ein Abgleiten oder Verrutschen der Vakuumschaltröhre von beziehungsweise auf dem Flachabschnitt verhindert. Zur Vereinfachung der Montage weist die vorbekannte Haltevorrichtung an einer Seite eine Art Scharnier auf, mit der zwei Hälften der Haltevorrichtung auseinander geklappt werden können. An einer dem Scharnier gegenüberliegenden Seite verfügt die Haltevorrichtung ferner über einen Schnappmechanismus, so dass ein Einspannen der eingeführten Vakuumschaltröhre ermöglicht ist. Zur Befestigung in einem Tragrahmen verfügt die Haltevorrichtung über Halteschienen, die in formkomplementäre Nuten des Tragrahmens einschiebbar sind, so dass die Vakuumschaltröhre durch die Haltevorrichtung an ihrer Antriebsseite zuverlässig und zentriert in dem Tragrahmen gehalten ist, wobei gleichzeitig die Beweglichkeit der Schaltstange ermöglicht ist. Der vorbekannten Haltevorrichtung haftet jedoch der Nachteil an, dass diese aus einem nicht leitenden Kunststoff gefertigt ist, so dass an spitzen oder eckigen mit einem Hochspannungspotenzial beaufschlagten Abschnitten der Schaltröhre hohe elektrische Felder oder Kriechströme entstehen. Die mit den vorbekannten Haltevorrichtungen ausgerüsteten Schalter weisen daher entweder einen diese hohen elektrischen Feldstärken berücksichtigen Polmittenabstand und somit eine raumgreifende Bauform auf oder sind hinsichtlich der erlaubten Betriebsspannungen auf entsprechend herabgesetzte Betriebsparameter begrenzt.Such a holding device is from the US 2001/0025829 A1 already known. The known holding device is adapted for holding a vacuum interrupter and has a circular-plate-shaped holding portion, which in operation rests against an end face of a vacuum interrupter, through which a shift rod movable in a longitudinal direction extends. The holding portion is connected to a substantially perpendicular to this extending holding portion which extends in an installed position around the contour of the inserted vacuum interrupter and thus prevents slipping or slipping of the vacuum interrupter from or on the flat portion. To simplify the assembly, the prior art holding device on one side of a kind of hinge with which two halves of the holding device can be folded apart. On a side opposite the hinge, the holding device further has a snap mechanism, so that a clamping of the inserted vacuum interrupter is made possible. For attachment in a support frame, the holding device has retaining rails which can be inserted into complementary form the grooves of the support frame, so that the vacuum interrupter is held by the holding device on its drive side reliable and centered in the support frame, at the same time the mobility of the shift rod is made possible. However, the prior art fixture adheres to the disadvantage that it is made of a non-conductive plastic, so that high electric fields or leakage currents occur at acute or angular portions of the interrupter which are subjected to a high-voltage potential. The switches equipped with the known holding devices therefore either have a pole center distance that takes account of these high electric field strengths and thus have a large-area design or are limited to correspondingly reduced operating parameters with regard to the permitted operating voltages.

Eine andere Haltevorrichtung ist aus JP 10 247444A bekannt. Die dort offenbarte Haltevorrichtung umfasst ein Feldsteuerelement zum Absteuern eines elektrischen Feldes entlang eines Zwischenraumes zwischen der Haltevorrichtung und einer Vakuumschaltröhre.Another holding device is off JP 10 247444A known. The holding device disclosed therein comprises a field control element for shunting an electric field along a gap between the holding device and a vacuum interrupter.

Aufgabe der vorliegenden Erfindung ist es daher, eine Haltevorrichtung der eingangs genannten Art bereitzustellen, mit der bei gleich bleibender Betriebsspannung des Schalters eine kompaktere Bauform eines Schalters oder bei gleich bleibender Bauform eine erhöhte Betriebsspannung herbeigeführt werden kann, der über eine solche Haltevorrichtung verfügt.Object of the present invention is therefore to provide a holding device of the type mentioned above, with the same operating voltage of the switch, a more compact design of a switch or a constant design, an increased operating voltage can be brought about, which has such a holding device.

Die Erfindung löst diese Aufgabe durch ein Feldsteuerelement zum Absteuern eines elektrischen Feldes, das während des Betriebs der Schaltröhre leitend mit einem Bestandteil der Schaltröhre verbindbar ist, der sich während des Betriebs der Schaltröhre auf Hochspannungspotenzial befindet, sowie Zentriermittel, die mit dem Halteabschnitt verbunden und der Durchgangsöffnung zugewandt sind.The invention achieves this object by means of a field control element for shunting off an electric field, which during the operation of the interrupter is conductively connectable to a component of the interrupter which is at high voltage potential during operation of the interrupter, as well as centering means, which are connected to the holding portion and facing the through hole.

Erfindungsgemäß ist in oder an der Haltevorrichtung ein Feldsteuerelement vorgesehen, das während des Betriebs, also bei einer eingesetzten mit Spannung beaufschlagten Schaltröhre, das Potenzial aufweist, mit dem der Bestandteil der Schaltröhre beaufschlagt ist, den das Feldsteuerelement kontaktiert. Der Abbau des während des Betriebs entstehenden elektrischen Feldes findet daher nicht mehr wie beim Stand der Technik zwischen dem auf Hochspannungspotential liegenden Bestandteil der Schaltröhre und einem auf Erdpotenzial liegenden Bauteil des Schalters statt, sondern zwischen dem Feldsteuerelement und dem Bauteil. Dabei ist das Feldsteuerelement wie üblich so ausgestaltet, dass Spitzen, scharfe Kanten oder dergleichen vermieden sind, an denen hohe Feldintensitäten entstehen könnten. Da das Feldsteuerelement mit einem Isolierstoff ummantelt ist, wird das hohe elektrische Feld im Isolierstoff abgesteuert. Mit anderen Worten kommt es gemäß der vorliegenden Erfindung zu einem kontrollierteren Absteuern des elektrischen Feldes. Die Haltevorrichtung weist daher nicht nur eine Haltefunktion oder gegebenenfalls eine Zentrierwirkung auf, sondern ermöglicht darüber hinaus die Erzeugung homogener Feldverläufe innerhalb des Schalterpols. Die Gefahr von Kriechströmen, Teilentladungen oder dergleichen ist daher erfindungsgemäß herabgesetzt, so dass kompaktere Bauformen oder eine höhere Betriebsspannungen ermöglicht sind. Die Ausgestaltung des Feldsteuerelements ist erfindungsgemäß beliebig, nur beispielsweise seien eingebettete metallische Netzstrukturen oder elektrisch leitende Oberflächenschichten aus Kunststoff, Lack, Metall oder dergleichen genannt. Die Zentriermittel sind zum Zentrieren der Haltevorrichtung bezüglich einer Schaltstange vorgesehen, welche fest mit einem Bewegkontakt der Schaltröhre verbunden ist und sich durch die von der Haltevorrichtung gehaltene Stirnseite der Schaltröhre erstreckt.According to the invention, a field control element is provided in or on the holding device, which has the potential during operation, that is to say when a switching tube is applied with voltage, which is acted upon by the component of the interrupter which the field control element contacts. The degradation of the electrical field produced during operation therefore no longer takes place, as in the prior art, between the high-voltage potential component of the interrupter and a grounded component of the switch, but between the field control element and the component. As usual, the field control element is designed in such a way that tips, sharp edges or the like are avoided, at which high field intensities could arise. Since the field control element is encased with an insulating material, the high electric field is dissipated in the insulating material. In other words, it comes according to the present invention to a more controlled Absteuern the electric field. The holding device therefore not only has a holding function or possibly a centering effect, but also allows the generation of homogeneous field courses within the Schalterpols. The risk of leakage currents, partial discharges or the like is therefore reduced according to the invention, so that more compact designs or higher operating voltages are made possible. According to the invention, the configuration of the field control element is arbitrary, for example only embedded metallic network structures or electrically conductive surface layers of plastic, paint, metal or the like may be mentioned. The centering means are provided for centering the holding device with respect to a switching rod, which is fixedly connected to a moving contact of the interrupter and extends through the held by the holding device end face of the interrupter.

Der Flanschabschnitt erstreckt sich vorteilhafterweise winklig und insbesondere rechtwinklig zu dem vorzugsweise ringscheibenförmig ausgebildeten Halteabschnitt. Dabei umschließt der Flanschabschnitt die Kontur der Stirnseite der Schaltröhre. Im Falle einer zylinderförmigen Schaltröhre ist der Halteabschnitt daher ringscheibenmäßig ausgestaltet, wobei sich der Flanschabschnitt an der Außenkontur des Ringabschnittes erstreckt. Dabei überragt der Flanschabschnitt im Betrieb die Schaltröhre seitlich und verhindert auf diese Weise ein Herabgleiten oder Verrutschen der Schaltröhre von beziehungsweise auf dem Halteabschnitt. Der Flanschabschnitt kann geschlossen um den Halteabschnitt herum verlaufen. Im Rahmen der Erfindung ist es jedoch ebenso möglich, dass der Flanschabschnitt sich nur an gewissen Abschnitten der Außenkontur des Halteabschnittes erstreckt. So ist es beispielsweise möglich, dass der Flanschabschnitt aus drei gleichmäßig über den Umfang verteilten Stegabschnitten besteht.The flange portion advantageously extends at an angle and in particular at right angles to the preferably annular disk-shaped holding section. The flange section encloses the contour of the end face of the interrupter. In the case of a cylindrical interrupter, the holding section is therefore configured in the form of an annular disc, with the flange section extending on the outer contour of the annular section. During operation, the flange section projects laterally beyond the interrupter tube and in this way prevents the interrupter from sliding or slipping off or on the holding section. The flange portion may be closed around the holding portion. In the context of the invention, however, it is also possible that the flange portion extends only at certain portions of the outer contour of the holding portion. Thus, for example, it is possible that the flange portion consists of three evenly distributed over the circumference web portions.

Vorteilhafterweise erstreckt sich das Feldsteuerelement in oder an dem Flanschabschnitt. Aufgrund der Anordnung des Flanschabschnittes außen an dem Halteabschnitt weist dieser zu den Komponenten des Schalterpols, die auf einem Erdpotenzial liegen, den geringsten Abstand auf. Aus diesem Grunde erfolgt die Feldabsteuerung bevorzugt zwischen dem in dem Flanschabschnitt angeordneten Feldsteuerelement und den auf Erdpotenzial liegenden Bauteilen.Advantageously, the field control element extends in or on the flange portion. Due to the arrangement of the flange on the outside of the holding section has this to the components of the switch pole, which are at a ground potential, the smallest distance. For this reason, the Feldabsteuerung preferably takes place between the arranged in the flange portion field control element and lying at ground potential components.

Vorteilhafterweise umfasst das Feldsteuerelement einen metallischen Kernbereich des Flanschabschnittes, der von einer Isolierung umgeben ist. Gemäß dieser vorteilhaften Weiterentwicklung ist das Feldsteuerelement zumindest teilweise von einem massiven metallischen Kernbereich des Flanschabschnittes ausgebildet. Der Flanschabschnitt kann somit fast ausschließlich aus dem Feldsteuerelement bestehen. Zur Isolation ist der Kernbereich lediglich von einer beispielsweise dünnwandigen Isolierung umgeben. Die dünnwandige Isolierung wird beispielsweise im Spritzgussverfahren aufgebracht.Advantageously, the field control element comprises a metallic core region of the flange portion, which is surrounded by an insulation. According to this advantageous further development, the field control element is at least partially formed by a solid metallic core region of the flange section. The flange portion can thus consist almost exclusively of the field control. For isolation, the core area is only of a thin-walled example Surrounded by insulation. The thin-walled insulation is applied by injection molding, for example.

Zweckmäßigerweise bildet das Feldsteuerelement den Halteabschnitt aus. Gemäß dieser vorteilhaften Weiterentwicklung ist der Halteabschnitt zumindest Teil des Feldsteuerelementes, wobei dieses entweder einen Kernbereich des Flanschabschnittes umfasst oder aber über zweckmäßig gebogene flächige Drahtnetze verfügt, die sich in einem Kunststoffteil des Flanschabschnittes erstrecken.Conveniently, the field control element forms the holding section. According to this advantageous further development, the holding section is at least part of the field control element, which either comprises a core region of the flange section or else has expediently curved flat wire nets which extend in a plastic part of the flange section.

Gemäß einer bevorzugten Weiterentwicklung der Erfindung ist der Halteabschnitt metallisch und einstückig mit einem ebenfalls metallischen Kernbereich des Flanschabschnittes ausgebildet, wobei der Kernbereich von einer Isolierung umgeben ist, so dass das Feldsteuerelement durch den Flanschabschnitt und den Kernbereich ausgebildet ist. Die auf diese Weise ausgebildete Haltevorrichtung ist besonders kostengünstig, da der Kernbereich des Flanschabschnittes sowie der Halteabschnitt durch übliche Metallherstellungsverfahren, beispielsweise durch Metall- Druckguss herstellbar ist. Schließlich wird der Kernbereich im Spritzgussverfahren von einer dünnwandigen Kunststoffschicht umgeben.According to a preferred development of the invention, the holding section is metallic and integrally formed with a likewise metallic core region of the flange section, wherein the core region is surrounded by insulation, so that the field control element is formed by the flange section and the core region. The holding device formed in this way is particularly cost-effective, since the core region of the flange portion and the holding portion can be produced by conventional metal production methods, for example by metal die casting. Finally, the core area is surrounded by a thin-walled plastic layer by injection molding.

Vorteilhafterweise weisen die Zentriermittel parallel zueinander verlaufende Haltebügel auf, die über eine Aufnahmenut verfügen, wobei Gewindeplättchen in der Aufnahmenut angeordnet sind, durch die sich eine auf die Durchgangsöffnung ausgerichtete Zentrierschraube erstreckt. Gemäß dieser Weiterentwicklung umfassen die Zentriermittel einfache Haltebügel, die beispielsweise einstückig mit dem Halteabschnitt ausgebildet sein können. Die Fertigung der Zentriermittel ist daher kostengünstig, da auch die im Weiteren notwendigen Gewindeplättchen geringpreisig sind.Advantageously, the centering on mutually parallel headband, which have a receiving groove, wherein threaded plates are arranged in the receiving groove through which extends a aligned on the through hole centering. According to this development, the centering means comprise simple retaining clips, which may for example be formed integrally with the retaining portion. The production of the centering is therefore inexpensive, as well as the subsequently necessary threaded plates are low in price.

Die Erfindung betrifft ferner einen Schalterpol mit wenigstens einer erfindungsgemäßen Haltevorrichtung.The invention further relates to a switch pole with at least one holding device according to the invention.

Der Schalterpol umfasst vorteilhafterweise einen Tragrahmen, der zum Beispiel aus einem mechanisch stabilen Kunststoff besteht. An dem Tragrahmen sind ein Eingangsanschluss sowie ein Abgangsanschluss befestigt, wobei sich zwischen dem Eingangs- und dem Abgangsanschluss eine Schaltröhre, wie beispielsweise eine Vakuumschaltröhre, erstreckt. Die Vakuumschaltröhre weist ein aus einem Isoliermaterial bestehendes hohlzylindrisches Gehäuse auf, das an seinen beiden Stirnseiten mit metallischen Abdeckungen verbunden ist. Die metallischen Abdeckungen der Stirnseiten sowie das Isoliergehäuse bilden ein vakuumdichtes Vakuumröhrengehäuse aus, wobei sich an einer Festkontaktseite des Vakuumröhrengehäuses ein feststehender Festkontaktbolzen durch die metallische Abdeckung hindurch erstreckt. Der Festkontaktbolzen trägt an seinem in das Vakuumröhrengehäuse hineinragenden Ende ein Festkontaktstück. Diesem liegt in einer Längsrichtung ein längsbeweglich geführtes Bewegkontäktstück gegenüber, das an dem freien Ende einer Schaltstange angebracht ist. Die Schaltstange erstreckt sich durch die dem Festkontaktbolzen gegenüberliegende metallische Abdeckung, wobei ein Metallfaltenbalg, der einerseits an dem Bewegkontaktstück oder an der Schaltstange und andererseits an der metallischen Abdeckung befestigt ist, die Beweglichkeit des Bewegkontaktstückes ermöglicht. In einer Kontaktstellung kontaktiert das Bewegkontaktstück das Festkontaktstück, so dass ein Stromfluss über die Vakuumschaltröhre ermöglicht ist. Bei einem Schaltvorgang wird das Bewegkontaktstück von dem Festkontaktstück getrennt, wobei zwischen den Kontaktstücken ein Lichtbogen gezogen wird, der bei einem Stromnulldurchgang in dem Vakuum der Vakuumschaltröhre gelöscht wird.The switch pole advantageously comprises a support frame, which consists for example of a mechanically stable plastic. Attached to the support frame are an input port and an out port, with a switching tube, such as a vacuum interrupter, extending between the input and output ports. The vacuum interrupter has a hollow cylindrical housing made of an insulating material, which is connected at its two end faces with metallic covers. The metallic covers of the end faces and the insulating housing form a vacuum-tight vacuum tube housing, with a fixed fixed contact pin extending through the metallic cover on a fixed contact side of the vacuum tube housing. The fixed contact pin carries at its projecting into the vacuum tube housing end a fixed contact piece. This is located in a longitudinal direction a longitudinally movable Bewegakäktstück opposite, which is attached to the free end of a shift rod. The shift rod extends through the metallic cover opposite the fixed contact pin, wherein a metal bellows, which is attached on the one hand to the Bewegkontaktstück or on the shift rod and on the other hand on the metallic cover, allows the mobility of the Bewegkontaktstückes. In a contact position, the moving contact piece contacts the fixed contact piece, so that a flow of current through the vacuum interrupter is made possible. In a switching operation, the moving contact piece is separated from the fixed contact piece, wherein an arc is drawn between the contact pieces, which is extinguished at a current zero crossing in the vacuum of the vacuum interrupter.

Die Haltevorrichtung ist zur Aufnahme der Schaltröhre innerhalb des Flanschabschnittes eingerichtet, wobei diese ein seitliches Abgleiten der Vakuumschaltröhre mit ihrer Stirnseite von dem Halteabschnitt verhindert. Ist die Haltevorrichtung an der Antriebsseite der Schaltröhre angeordnet, durchragt die Schaltstange die in dem Halteabschnitt vorgesehene Durchgangsöffnung, so dass eine Längsbewegung der Schaltröhre ermöglicht ist. Ist die Haltevorrichtung an der von der Antriebsseite abgewandten Stirnseite der Schaltröhre angeordnet, durchragt der Festkontaktbolzen die Durchgangsöffnung. Zur Befestigung der Haltevorrichtung an dem Tragrahmen verfügt die Haltevorrichtung über zweckmäßige Tragrahmenbefestigungen.The holding device is adapted to receive the interrupter within the flange portion, which prevents lateral slipping of the vacuum interrupter with its front side of the holding portion. If the holding device is arranged on the drive side of the interrupter, the shift rod extends through the passage opening provided in the holding section, so that a longitudinal movement of the interrupter is made possible. If the holding device is arranged on the end face of the interrupter facing away from the drive side, the fixed contact pin projects through the passage opening. For fixing the holding device to the support frame, the holding device has appropriate support frame fastenings.

Figur 1 zeigt ein erstes Ausführungsbeispiel eines erfindungsgemäßen Schalterpols 1 in einer perspektivischen Darstellung. Der Schalterpol 1 weist einen mechanisch festen Tragrahmen 2 auf, an dem ein Polkopfabschnitt 3b eines Ein-, gangsanschluss 3 fest verschraubt ist. Hierzu dient ein sich in Querrichtung erstreckender Befestigungssteg 4 mit Befestigungslöchern zum Anschrauben des Polkopfabschnittes 3b. Der Befestigungssteg 4 weist ferner eine Durchgangsöffnung 5 auf, durch die hindurch ein Festschrauben einer Vakuumschaltröhre 6 als Schaltröhre an dem Eingangsanschluss 5 ermöglicht ist. Die Vakuumschaltröhre 6 besteht aus einem hohlzylindrischen Keramikgehäuse 7, das aus zwei Teilen zusammengesetzt ist, die in der Mitte des Keramikgehäuses unter Zwischenlegung eines Zwischenflansches miteinander verbunden sind. An den Stirnseiten ist das Keramikgehäuse 7 durch metallische Abdeckungen, die in Figur 1 nicht sichtbar sind, verschlossen, so dass ein vakuumdichtes Gehäuse ausgebildet ist. An der in Figur 1 oberen Seite der Vakuumschaltröhre 6 durchragt ein Festkontaktbolzen die obere metallische Abdeckung, wobei an der in dem Vakuumgehäuse angeordneten freien Seite des Festkontaktbolzens ein Festkontaktstück ortsfest gehalten ist. Dem Festkontaktstück gegenüberliegend ist ein längs beweglich geführtes Bewegkontaktstück vorgesehen, das mittels einer Schaltstange beweglich gehalten ist. Die Schaltstange durchragt eine einem Abgangsanschluss 8 zugewandte metallische Abdeckung, wobei ein Metallfaltenbalg für die axiale Bewegungsfreiheit der Schaltstange sorgt. Zur Halterung der Vakuumschaltröhre 6 an ihrer vom Befestigungssteg 4 abgewandten Seite ist eine Haltevorrichtung 9 vorgesehen, die über eine Tragrahmenbefestigung 10 verfügt, mit der die Haltevorrichtung 9 in dem Tragrahmen 2 fest verankert ist. FIG. 1 shows a first embodiment of a switch pole 1 according to the invention in a perspective view. The switch pole 1 has a mechanically fixed support frame 2, on which a pole head section 3b of an input, connection 3 is firmly screwed. This purpose is served by a transversely extending fastening web 4 with mounting holes for screwing the pole head section 3b. The fastening web 4 further has a through-opening 5, through which a screwing of a vacuum interrupter 6 as a interrupter at the input connection 5 is made possible. The vacuum interrupter 6 consists of a hollow cylindrical ceramic housing 7, which is composed of two parts which are interconnected in the middle of the ceramic housing with the interposition of an intermediate flange. At the end faces, the ceramic housing 7 by metallic covers, which in FIG. 1 are not visible, closed, so that a vacuum-tight housing is formed. On the upper side of the vacuum interrupter 6 in FIG. 1, a fixed contact pin projects through the upper metallic cover, wherein a fixed contact piece is held stationary on the free side of the fixed contact pin arranged in the vacuum housing. The fixed contact piece opposite a longitudinally movably guided Bewegkontaktstück is provided, which is movably held by a shift rod. The switching rod protrudes through a metallic cover facing an outlet connection 8, a metal bellows providing the axial freedom of movement of the switching rod. For holding the vacuum interrupter 6 on its side facing away from the fastening web 4 side, a holding device 9 is provided which has a support frame attachment 10, with which the holding device 9 is firmly anchored in the support frame 2.

Eine weitere Haltvorrichtung 9 ist an der Stirnseite der Vakuumschaltröhre 6 angeordnet, die dem Befestigungssteg 4 zugewandt ist.Another holding device 9 is arranged on the end face of the vacuum interrupter 6, which faces the fastening web 4.

Zum Antrieb des Bewegkontaktstückes ist die Schaltstange über eine zweckmäßige Hebelmechanik 11 mit einem Antrieb verbindbar, der die zum Schalten notwendige Bewegungsenergie erzeugt.To drive the Bewegkontaktstückes the shift rod is connected via a suitable lever mechanism 11 with a drive that generates the necessary kinetic energy for switching.

Figur 2 zeigt ein weiteres Ausführungsbeispiel eines erfindungsgemäßen Schalterpols 1, der den gleichen Tragrahmen 2, wie das Ausführungsbeispiel gemäß Figur 1, aufweist. In diesem Ausführungsbeispiel ist die Isolierung jedoch durch zusätzliche Isolierabdeckungen 12 verstärkt, die in zweckmäßigen figürlich nicht dargestellten Rastnuten einrastbar sind. FIG. 2 shows a further embodiment of a switch pole 1 according to the invention, the same support frame 2, as the embodiment according to FIG. 1 , having. In this embodiment, however, the insulation is reinforced by additional insulating covers 12 which can be latched in functional figuratively not shown locking grooves.

Figur 3 zeigt das Ausführungsbeispiel gemäß Figur 2 in einer Querschnittsansicht. In dieser Ansicht ist erkennbar, dass der Eingangsanschluss 3 neben dem in Figur 1 gezeigten Polkopfabschnitt 3b ferner einen Längsabschnitt 3a umfasst. Der Polkopfabschnitt 3b ist mit dem Festkontaktbolzen 13 der Vakuumschaltröhre 6 verschraubt, während der Längsabschnitt 3a an dem Polkopfabschnitt 3b befestigt, beispielsweise verschraubt ist. Über die Länge des lösbar angebrachten Längsabschnittes 3a ist somit auf einfache Weise die Maulweite des Schalterpols, also der Abstand eines an dem Eingangsanschluss 3 befestigten Leiters von einem an dem Abgangsanschluss 8 befestigten Leiters, einstellbar. FIG. 3 shows the embodiment according to FIG. 2 in a cross-sectional view. In this view, it can be seen that the input terminal 3 next to the in FIG. 1 Polhead portion 3b further comprises a longitudinal portion 3a. The pole head portion 3b is bolted to the fixed contact pin 13 of the vacuum interrupter 6, while the longitudinal portion 3a attached to the pole head portion 3b, for example, is screwed. Over the length of the removably mounted longitudinal portion 3a is thus easily the jaw width of the Schalterpols, ie the distance of a conductor attached to the input terminal 3 of a conductor attached to the outgoing terminal 8, adjustable.

Eine dem Festkontaktbolzen 13 gegenüberliegende Schaltstange 14 ist über ein flexibles Stromband 15 mit dem Abgangsanschlussstück 8 verbunden. Zur Isolation der Schaltstange 14 ist eine topfförmige Isolierung 16 vorgesehen, über welche die Schaltstange 14 mit der Hebelmechanik 11 verbunden ist.A the fixed contact pin 13 opposite shift rod 14 is connected via a flexible current band 15 to the outgoing connector 8. For isolation of the shift rod 14, a pot-shaped insulation 16 is provided, via which the shift rod 14 is connected to the lever mechanism 11.

In Figur 3 ist ferner erkennbar, dass die Schaltstange 14 eine Stirnseite 17 einer metallischen Abdeckung 18 der Vakuumschaltröhre 6 durchragt, wobei eine Führungshülse 19 fest mit der Abdeckung 18 verbunden ist. Die Stirnseite 17 liegt auf der Haltevorrichtung 9 auf. An der dem Befestigungssteg 4 zugewandten Stirnseite der Vakuumschaltröhre 6 ist eine weitere Haltevorrichtung 9 zum Zentrieren der Vakuumschaltröhre 9 und zur Absteuerung des elektrischen Feldes vorgesehen.In FIG. 3 It can also be seen that the shift rod 14 extends through an end face 17 of a metallic cover 18 of the vacuum interrupter 6, wherein a guide sleeve 19 is fixedly connected to the cover 18. The end face 17 rests on the holding device 9. At the attachment web 4 facing end side of the vacuum interrupter 6, a further holding device 9 is provided for centering the vacuum interrupter 9 and for controlling the electric field.

Figur 4 zeigt eine perspektivische Ansicht der Haltevorrichtung 9, die einen ringscheibenförmigen Halteabschnitt 20 sowie einen sich diesbezüglich rechtwinklig erstreckenden Flanschabschnitt 21 aufweist. Der Halteabschnitt 20 weist eine Durchgangsöffnung 22 auf, durch die sich im eingebauten Zustand die Schaltstange 14 und die Führungshülse 19 hindurch erstrecken. Der Durchgangsöffnung 22 zugewandt sind Zentriermittel in Form von parallel zueinander angeordneten Haltebügeln 23 vorgesehen, die jeweils zur Aufnahme eines Gewindeplättchens eingerichtet sind. Dabei weist jedes Gewindeplättchen eine Gewindeschraube auf, die sich zur Durchgangsöffnung 22 hin erstreckt. Durch Einschrauben der Gewindeschraube in das Gewindeplättchen kontaktiert diese die fest mit der Vakuumschaftröhre verbundene Führungshülse 19, so dass durch die Stellung der Zentrierschrauben ein Zentrieren der Vakuumschaltröhre 6 in der Haltevorrichtung 9 ermöglicht ist. Der Flanschabschnitt 21 ist mit zwei krallenförmigen Tragrahmenbefestigungen 10 verbunden, die, wie in Figur 1 erkennbar ist, zum Halten der Haltevorrichtung 9 in dem Tragrahmen 2 eingerichtet sind. FIG. 4 shows a perspective view of the holding device 9, which has an annular disc-shaped holding portion 20 and in this respect at right angles extending flange portion 21. The holding portion 20 has a passage opening 22 through which the shift rod 14 and the guide sleeve 19 extend in the installed state. The through hole 22 facing centering means are provided in the form of mutually parallel brackets 23, which are each adapted to receive a threaded plate. In this case, each threaded plate on a threaded screw which extends to the through hole 22 through. By screwing the threaded screw into the threaded plate, the latter makes contact with the guide sleeve 19 fixedly connected to the vacuum shaft tube, so that centering of the vacuum interrupter 6 in the holding device 9 is made possible by the position of the centering screws. The flange portion 21 is connected to two claw-shaped support frame fixtures 10, which, as in FIG. 1 can be seen, are arranged for holding the holding device 9 in the support frame 2.

Figur 5 zeigt die Haltevorrichtung 9 gemäß Figur 4 in einer Querschnittsansicht. In dieser Darstellung ist erkennbar, dass der Flanschabschnitt 21 aus einem Kernabschnitt 24 besteht, der einstückig mit dem Halteabschnitt 20 ausgebildet und von einer dünnwandigen Isolierung 25 umgeben ist. Dabei liegt der Halteabschnitt 20 während des Betriebs leitend auf der metallischen Abdeckung 18 der Vakuumschaltröhre 6 auf, so dass durch den Kernabschnitt 24 und dem Halteabschnitt 20 ein Feldsteuerelement ausgebildet ist. In Figur 5 ist weiterhin erkennbar, dass die Haltevorrichtung einen durch den Flanschabschnitt 21 begrenzten Innendurchmesser aufweist, der etwas größer ist als der Außendurchmesser des Keramikgehäuses 7 der Vakuumschaltröhre 6. Mit anderen Worten ist die Haltevorrichtung 9 formkomplementär zur Stirnseite der Vakuumschaltröhre 6 ausgebildet. Darüber hinaus ist der Innendurchmesser der Durchgangsöffnung 22 an den Außendurchmesser der Führungshülse 19 angepasst, so dass diese durch die Durchgangsöffnung 22 hindurchführbar ist. Bei einer figürlich nicht dargestellten Abwandlung der Erfindung ist der Innendurchmesser des Flanschabschnittes 21 lediglich etwas größer als der Außendurchmesser der metallischen Abdeckung 18, jedoch etwas kleiner als der Außendurchmesser des Keramikgehäuses 7 der Vakuumschaltröhre 6. Mit anderen Worten bilden die metallische Abdeckung 18 und das Keramikgehäuse 7 eine umfänglich geschlossen umlaufende Stufe der Vakuumschaltröhre 6 aus, wobei nur die metallische Abdeckung 18 von dem Flanschabschnitt 21 ausgenommen ist und eine an diesen angepasste Längserstreckung aufweist. FIG. 5 shows the holding device 9 according to FIG. 4 in a cross-sectional view. In this illustration, it can be seen that the flange portion 21 consists of a core portion 24 formed integrally with the holding portion 20 and surrounded by a thin-walled insulation 25. In this case, the holding portion 20 is conductive during operation on the metallic cover 18 of the vacuum interrupter 6, so that a field control element is formed by the core portion 24 and the holding portion 20. In FIG. 5 Furthermore, it can be seen that the holding device has a limited by the flange 21 inner diameter which is slightly larger than the outer diameter of the ceramic housing 7 of the vacuum interrupter 6. In other words, the holding device 9 is complementary to the end face of the vacuum interrupter 6 formed. In addition, the inner diameter of the through hole 22 is adapted to the outer diameter of the guide sleeve 19, so that it can be passed through the through hole 22. In a figuratively not shown modification of the invention, the inner diameter of the flange portion 21 is only slightly larger than the outer diameter of the metallic cover 18, but slightly smaller than the outer diameter of the ceramic housing 7 of the vacuum interrupter 6. In other words, form the metallic cover 18 and the ceramic housing. 7 a circumferentially closed circumferential stage of the vacuum interrupter 6, wherein only the metallic cover 18 is excluded from the flange portion 21 and has a length adapted to this.
