Description

Messwandler für den Einsatz in einer gasisolierten Hochspannungsschaltanlage weisen ein in einem fluiddichten Gehäuse angeordnetes Aktivteil auf, das einerseits mit der Schaltanlage und andererseits mit einer Auswertungseinheit verbunden ist. Bei Prüfungen der Schaltanlage muss die Verbindung zwischen Aktivteil und der Schaltanlage getrennt werden, da sonst das Aktivteil Schaden nehmen könnte. Bisher sind einphasige Messwandler mit einem Aktivteil in einem Gehäuse und mehrphasige, meist dreiphasige, Messwandler, die mehrere rotationssymmetrisch im Gehäuse angeordnete Aktivteile aufweisen, bekannt. Für diese sind verschiedene Trennvorrichtungen bekannt.
So beschreibt die DE 10 2011 007 900 A1 einen einphasigen Spannungswandler mit einem Schwenkarm, der eine Verbindung des Aktivteils mit der Schaltanlage herstellt oder trennt.
In der EP 1 610 352 A1 ist ein mehrphasiger Messwandler gezeigt, bei der die Verbindung zwischen Aktivteil und Schaltanlage durch eine seitliche Bewegung, also senkrecht zur direkten Verbindungslinie zwischen Aktivteil und Schaltanlage hergestellt oder getrennt werden kann. In einer anderen Ausführungsform werden über einen Träger miteinander verbundene Kontakte, die über ein flexibles Kabel mit dem Aktivteil verbunden sind, mittels einer Schubstange in einer Richtung parallel zur Verbindungslinie zwischen Aktivteil und Schaltanlage bewegt, und so die Verbindung hergestellt oder getrennt. Die EP 2 144 261 A1 beschreibt ein gasisolierter Messwandler nach dem Oberbegriff des Anspruchs 1. Aufgabe der Erfindung ist es, einen Messwandler mit mehreren Aktivteilen mit einer verbesserten Trennvorrichtung anzugeben.
Erfindungsgemäß ist dazu ein gasisolierter Messwandler, der zur Messung von Hochspannungen dient, vorgesehen. Der Messwandler weist mehrere in einem fluiddichten Gehäuse angeordnete Wandleranordnungen zur Umwandlung einer Hochspannung in eine Messspannung vor. Jede Wandleranordnung umfasst ein Aktivteil, einen durch das Gehäuse geführten Hochspannungskontakt, einen mit dem Aktivteil elektrisch verbundenen festen Kontakt und einen mit dem festen Kontakt elektrisch verbundenen beweglichen Kontakt. Der Messwandler umfasst außerdem eine von außerhalb des Gehäuses betätigbare Trennvorrichtung mittels der eine Verbindung der beweglichen Kontakte mit den Hochspannungskontakten herstellbar beziehungsweise trennbar ist. Die Trennvorrichtung weist dazu ein die beweglichen Kontakte miteinander verbindendes Verbindungselement und Verstellmittel zur Bewegung des Verbindungselementes in einer Stellrichtung. Eine mittels der Verstellmittel auf das Verbindungselement übertragene Bewegung führt so zu einer synchronen Bewegung der beweglichen Kontakte in Stellrichtung. Der feste Kontakt ist dabei als Führung für den beweglichen Kontakt in Stellrichtung ausgebildet. Die Bewegung ist vorzugsweise eine lineare Bewegung und die Führung ist als Linearführung ausgebildet. Die Führung kann beispielsweise in Form von Nut und Feder, als Schwalbenschwanzführung, als Schienenführung, als Wälzführung, als Gleitlagerführung oder als Teleskopführung ausgebildet sein. Während der Bewegung des beweglichen Kontaktes wird durch die Führung ein guter elektrischer Kontakt zwischen beweglichem Kontakt und festem Kontakt hergestellt. Außerdem dient die Führung dazu, die Bewegung des beweglichen Kontaktes in Stellrichtung zu ermöglichen und eine Bewegung in Richtung senkrecht zur Stellrichtung zu beschränken. Dadurch, dass die Führung des beweglichen Kontaktes durch den festen Kontakt hergestellt wird, wird einerseits der mechanische Aufwand verringert und andererseits ein guter elektrischer Kontakt zwischen beweglichem Kontakt und festem Kontakt gewährleistet.Instrument transformers for use in a gas-insulated high-voltage switchgear have an active part arranged in a fluid-tight housing, which is connected, on the one hand, to the switchgear and, on the other hand, to an evaluation unit. When testing the switchgear, the connection between the active part and the switchgear must be disconnected, as otherwise the active part could be damaged. So far, single-phase transducers with an active part in a housing and multiphase, usually three-phase, transducer having a plurality of rotationally symmetrically arranged in the housing active parts known. For this, various separation devices are known.
That's how it describes DE 10 2011 007 900 A1 a single-phase voltage converter with a swivel arm, which establishes or separates a connection of the active part with the switchgear.
In the EP 1 610 352 A1 is a multi-phase transducer shown, in which the connection between the active part and switchgear can be made or separated by a lateral movement, ie perpendicular to the direct line connecting active part and switchgear. In another embodiment, contacts connected to one another via a carrier, which are connected to the active part via a flexible cable, are moved by means of a push rod in a direction parallel to the connection line between the active part and the switchgear, thus establishing or disconnecting the connection. The EP 2 144 261 A1 describes a gas-insulated transducer according to the preamble of claim 1. The object of the invention is to provide a transducer with multiple active parts with an improved separator.
According to the invention, a gas-insulated transducer, which serves to measure high voltages, is provided for this purpose. The transducer has a plurality of transducer assemblies arranged in a fluid-tight housing for converting a high voltage into a measured voltage. Each transducer assembly includes an active part, a high voltage contact passed through the housing, a fixed contact electrically connected to the active part, and a movable contact electrically connected to the fixed contact. The transducer also includes an operable from outside the housing separating device by means of a connection of the movable contacts with the high-voltage contacts can be produced or separated. For this purpose, the separating device has a connecting element which interconnects the movable contacts and adjusting means for moving the connecting element in a setting direction. A transmitted to the connecting element by means of the adjusting movement thus leads to a synchronous movement of the movable contacts in the direction of adjustment. The fixed contact is designed as a guide for the movable contact in the direction of adjustment. The movement is preferably a linear movement and the guide is designed as a linear guide. The guide may be formed, for example, in the form of tongue and groove, as a dovetail guide, as a rail guide, as a rolling guide, as a sliding bearing guide or as a telescopic guide. During the movement of the movable contact, a good electrical contact between movable contact and fixed contact is established by the guide. In addition, the guide is used to allow the movement of the movable contact in the direction of adjustment and to restrict a movement in the direction perpendicular to the direction of adjustment. The fact that the leadership of the movable contact is made by the fixed contact, on the one hand reduces the mechanical complexity and on the other hand ensures good electrical contact between the movable contact and fixed contact.

Vorteilhaft weist der feste Kontakt ein rohrförmiges Ende und der bewegliche Kontakt ein stabförmiges Ende auf, das stabförmige Ende ist dabei in das rohrförmige Ende einschiebbar. Dies ermöglicht eine besonders einfache Montage der Trennvorrichtung und bietet eine besonders gute Führung des beweglichen Kontaktes. Der elektrische Kontakt kann beispielsweise durch Feder- oder Lamellenkontakte hergestellt werden. Erfindungsgemäß weisen die Verstellmittel eine mit dem Verbindungselement verbundene Schubstange auf, die mittels eines außerhalb des Gehäuses angeordneten Antriebs in Stellrichtung bewegbar ist. Die Schubstange überträgt dabei die Bewegung des Antriebs auf das Verbindungselement, das wiederum seine Bewegung auf die beweglichen Kontakte überträgt, wodurch auf besonders einfache Weise eine synchrone Bewegung der beweglichen Kontakte erreicht wird.
Ferner wird bevorzugt, dass der Antrieb mit der Schubstange über ein Getriebe gekoppelt ist, das eine rotierende Bewegung des Antriebs in eine lineare Stellbewegung der Schubstange umsetzt. Das Getriebe ist dazu bevorzugt im Inneren des Gehäuses angeordnet und kann beispielsweise ein Exzentergetriebe, ein Schneckengetriebe oder ein Trapezgewindegetriebe sein. Somit wird vom Antrieb eine rotierende Bewegung ins Innere des Gehäuses übertragen, die dort in eine lineare Bewegung umgesetzt wird. Dies verringert einerseits den für den Antrieb erforderlichen Platzbedarf, andererseits ist eine rotierende Bewegung einfacher gasdicht durch die Gehäusewand zu führen, als eine lineare.
Besonders vorteilhaft ist das Getriebe als Exzentergetriebe ausgebildet, da dieses besonders einfach aufgebaut und montierbar ist.Advantageously, the fixed contact on a tubular end and the movable contact on a rod-shaped end, the rod-shaped end is inserted into the tubular end. This allows a particularly simple installation of the separation device and offers a particularly good guidance of the moving contact. The electrical contact can be made for example by spring or lamellar contacts. According to the invention, the adjusting means comprise a connecting rod connected to the connecting rod, which is movable by means of a drive arranged outside of the housing in the adjusting direction. The push rod transmits the movement of the drive on the connecting element, which in turn transmits its movement to the movable contacts, whereby a particularly simple manner, a synchronous movement of the movable contacts is achieved.
Furthermore, it is preferred that the drive is coupled to the push rod via a transmission which converts a rotary movement of the drive into a linear actuating movement of the push rod. The transmission is preferably arranged in the interior of the housing and may for example be an eccentric, a worm gear or a trapezoidal thread gear. Thus, the drive transmits a rotating movement into the interior of the housing, which is converted there into a linear movement. On the one hand this reduces the space required for the drive, on the other hand, a rotating movement is easier to guide gas-tight through the housing wall, as a linear.
Particularly advantageously, the transmission is designed as an eccentric, since this is particularly simple in construction and mountable.

Des Weiteren sieht die Erfindung vor, dass zumindest zwei parallel zueinander angeordnete und mittels des Antriebs gleichzeitig bewegbare Schubstangen mit dem Verbindungselement verbunden sind, wodurch ein besserer Schutz vor Verkantung des Verbindungselements erreicht wird. Erfindungsgemäß ist jede der zumindest zwei Schubstangen über ein Getriebe mit dem Antrieb gekoppelt. Ferner wird bevorzugt, dass die Aktivteile derart in einer Reihe zueinander angeordnet sind, dass sie eine gemeinsame Wicklungsachse aufweisen. Die Aktivteile sind scheibenartig rotationssymmetrisch um die Wicklungsachse aufgebaut, die durch einen Kernschenkel verläuft. Alle Kernschenkel liegen dadurch in einer Ebene, in der auch die Wicklungsachse verläuft. Die Wicklungsebene liegt senkrecht zu dieser Ebene. Dies ermöglicht zum Einen eine besonders platzsparende Anordnung der Aktivteile und zum Anderen eine besonders einfach aufgebaute Tragrahmenstruktur für die Kerne.
Es wird auch bevorzugt, dass der Antrieb mit dem Getriebe über eine senkrecht zur Stellrichtung angeordnete Antriebswelle gekoppelt ist. Dies erlaubt eine besonders platzsparende Anordnung des Antriebs.Furthermore, the invention provides that at least two parallel arranged and simultaneously movable by means of the drive push rods are connected to the connecting element, whereby a better protection against canting of the connecting element is achieved. According to the invention, each of the at least two push rods is coupled to the drive via a transmission. Furthermore, it is preferred that the active parts are arranged in a row to one another such that they have a common winding axis. The active parts are disk-like rotationally symmetrical around the winding axis, which runs through a core leg. All core legs are thus in a plane in which the winding axis runs. The winding plane is perpendicular to this plane. This allows, on the one hand, a particularly space-saving arrangement of the active parts and, on the other hand, a particularly simple construction of a support frame structure for the cores.
It is also preferred that the drive is coupled to the transmission via a drive shaft arranged perpendicular to the direction of adjustment. This allows a particularly space-saving arrangement of the drive.

Die Figuren zeigen zur Veranschaulichung eine konkrete Ausführungsform. Die Erfindung ist allerdings nicht auf diese beschränkt.The figures show by way of illustration a concrete embodiment. However, the invention is not limited to these.

Die Figur 1 zeigt einen erfindungsgemäßen Messwandler 1 mit einem gasisolierten Gehäuse 2, das hier teiltransparent dargestellt ist. Das Gehäuse 2 hat einen ovalen Querschnitt und ist an einem Ende mit einem Deckel 3 verschlossen. Am dem Deckel 3 gegenüberliegenden Ende befinden sich drei mit Durchführungen 4 verschlossene Öffnungen. Die Durchführungen weisen einen Isolatorkörper 5 und einen durch diesen gasdicht geführten Hochspannungskontakt 6 auf. Das Gehäuse kann weitere Vorrichtungen wie Ventile 31, Überdruckablassvorrichtungen 32 oder einen Sekundäranschlusskasten 33 aufweisen. Auf der Außenseite einer Gehäusewand ist außerdem ein Antrieb 7 angeordnet. Im Folgenden wird die Ansicht von der Seite des Messwandlers 1 mit dem Antrieb 7 als Vorderansicht, die Ansicht von der gegenüberliegenden Seite als Rückansicht bezeichnet.The FIG. 1 shows a transducer 1 according to the invention with a gas-insulated housing 2, which is shown partially transparent here. The housing 2 has an oval cross section and is closed at one end with a cover 3. At the opposite end of the lid 3 are three openings with openings 4 closed. The bushings have an insulator body 5 and a gas-tight guided by this high-voltage contact 6. The housing may have other devices such as valves 31, overpressure relief devices 32 or a secondary connection box 33. On the outside of a housing wall, a drive 7 is also arranged. In the following, the view from the side of the transducer 1 with the drive 7 is referred to as a front view, the view from the opposite side as a rear view.

Die Figuren 2 und 3 zeigt die Rückansicht des Messwandlers 1 aus der Figur 1, wobei hier vom Gehäuse 2 lediglich der Deckel 3 dargestellt ist. Im Inneren des Gehäuses befinden sich drei Kerne 8 aus lamellierten Eisenblechen. Die Kerne 8 werden jeweils durch einen am Deckel 3 befestigten Rahmen 28 gehalten. Jeder Kern 8 besteht aus jeweils zwei horizontalen und zwei vertikalen im Rechteck angeordneten Schenkeln. Auf jeweils einem horizontalen Schenkel, in den Figuren dem unteren, jedes Kerns 8 ist ein Aktivteil 9 angeordnet. Die Aktivteile 9 sind hier induktive Spannungswandler mit jeweils einer Primärwicklung und einer oder mehreren Sekundärwicklungen, die um eine Wicklungsachse 40 gewickelt sind. Die Wicklungsebene verläuft senkrecht zur Wicklungsachse 40. Die Primärwicklung ist mit einem durch Hochspannungsdurchführung 4 in das Gehäuse 2 geführten Leiter verbunden, der wiederum mit einer Hochspannungsleitung verbunden ist. Die Sekundärwicklung ist über Anschlusskabel, die durch eine im Deckel 3 angeordnete, hier nicht sichtbare, Durchführung mit dem Sekundäranschlusskasten 33 verbunden. Eine ringförmige um jedes Aktivteil 9 angeordnete Hochspannungselektrode schirmt die auf Erdpotential liegenden Kerne 8 und Rahmen 28 vor dem Hochspannungspotential ab. Die Aktivteile 9 sind in einer Reihe zueinander angeordnet, so dass die Wicklungsebenen parallel zueinander angeordnet sind. Die Schenkel, auf denen die Wicklungen angeordnet sind, sind längs hintereinander entlang der Wicklungsachse 40 angeordnet. Die drei Aktivteile 9 sind dazu vorgesehen, die Spannung der drei Phasen einer Hochspannungsleitung auf eine einfach zu messende Messspannung zu transformieren. Die Hochspannung beträgt dabei von einigen zehn Kilovolt bis zu mehreren hundert Kilovolt. Die Aktivteile 9 transformieren diese Hochspannung mit hoher Genauigkeit auf einen Wert deutlich unter tausend Volt, meist etwa einhundert Volt bei anliegender Nennspannung. Dazu sind die Primärwicklungen der Aktivteile 9 mit jeweils einer Phase der Hochspannungsleitung verbunden. Diese Verbindung muss zu Prüfzwecken auftrennbar sein. Figur 2 zeigt die Verbindung in geschlossenem Zustand, Figur 3 in geöffnetem.The Figures 2 and 3 shows the rear view of the transducer 1 from the FIG. 1 , wherein here from the housing 2, only the lid 3 is shown. Inside the housing are three cores 8 made of laminated iron sheets. The cores 8 are held by a frame 28 attached to the lid 3, respectively. Each core 8 consists of two horizontal and two vertical legs arranged in a rectangle. On each of a horizontal leg, in the figures the lower, each core 8, an active part 9 is arranged. The active parts 9 are here inductive voltage converter with one each Primary winding and one or more secondary windings, which are wound around a winding axis 40. The winding plane is perpendicular to the winding axis 40. The primary winding is connected to a guided by high-voltage bushing 4 in the housing 2 conductor, which in turn is connected to a high voltage line. The secondary winding is connected via connecting cables which are connected to the secondary terminal box 33 by means of a bushing arranged in the cover 3 and not visible here. An annular high-voltage electrode arranged around each active part 9 shields the cores 8 and frame 28, which are at ground potential, from the high-voltage potential. The active parts 9 are arranged in a row to each other, so that the winding planes are arranged parallel to each other. The legs on which the windings are arranged are arranged longitudinally one behind the other along the winding axis 40. The three active parts 9 are intended to transform the voltage of the three phases of a high voltage line to an easily measured measuring voltage. The high voltage is from a few tens of kilovolts to several hundred kilovolts. The active parts 9 transform this high voltage with high accuracy to a value well below a thousand volts, usually about one hundred volts with applied nominal voltage. For this purpose, the primary windings of the active parts 9 are each connected to one phase of the high-voltage line. This connection must be separable for testing purposes. FIG. 2 shows the connection in the closed state, FIG. 3 in open.

Die Hochspannung wird über die Hochspannungskontakte 6 in das Gehäuse 2 hinein geführt. Die Hochspannungskontakte 6 sind Leiterstücke, die gasdicht durch die Isolatorkörper 5 der Durchführungen 4 geführt sind.The high voltage is passed through the high voltage contacts 6 in the housing 2 into it. The high-voltage contacts 6 are conductor pieces which are guided gas-tight through the insulator body 5 of the bushings 4.

Die Primärwicklungen der Aktivteile 9 sind jeweils mit einem festen Kontakt 10 elektrisch verbunden. Die Verbindung kann beispielsweise über einen mit dem festen Kontakt 10 verbundenen Federkontakt hergestellt sein. Der feste Kontakt 10 weist ein rohrförmiges Ende 12 auf, in das ein stabförmiges Ende 13 eines beweglichen Kontaktes 11 gesteckt ist. Das stabförmige Ende 13 lässt sich teleskopartig in einer Stellrichtung 41 in das rohrförmige Ende 12 hinein und aus diesem hinaus bewegen. Vorzugsweise ist das stabförmige Ende 13 in dem rohrförmigen Ende 12 geführt. Alternative Ausführungen sind möglich. Beispielsweise könnte der feste Kontakt ein stabförmiges Ende 13 und der bewegliche Kontakt ein rohrförmiges Ende 12 aufweisen, oder einer der Kontakte weist eine Nut auf, der andere eine in der Nut geführte korrespondierende Feder.The primary windings of the active parts 9 are each electrically connected to a fixed contact 10. The connection can be made, for example, via a spring contact connected to the fixed contact 10. The fixed contact 10 has a tubular end 12 into which a rod-shaped end 13 a movable contact 11 is inserted. The rod-shaped end 13 can be moved telescopically in a direction of adjustment 41 into the tubular end 12 and out of this. Preferably, the rod-shaped end 13 is guided in the tubular end 12. Alternative versions are possible. For example, the fixed contact could have a rod-shaped end 13 and the movable contact could have a tubular end 12, or one of the contacts could have a groove, the other a corresponding spring guided in the groove.

Jeweils ein Aktivteil 9 mit Kern 8 bildet zusammen mit einem Hochspannungskontakt 6, einem festen Kontakt 10 und einem beweglichen Kontakt 11 eine Wandleranordnung im Sinne der Erfindung.In each case an active part 9 with core 8 forms, together with a high-voltage contact 6, a fixed contact 10 and a movable contact 11, a transducer arrangement in the context of the invention.

Im geschlossenen Zustand steht ein annähernd kugelförmiges Kontaktstück 14 des beweglichen Kontaktes 11 mit dem Hochspannungskontakt 6 in Berührung und stellt eine elektrische Verbindung vom Hochspannungskontakt 6 über den beweglichen Kontakt 11 und den festen Kontakt 10 zur Primärwicklung des Aktivteils 9 her. Der Hochspannungskontakt 6 kann eine kugelabschnittsförmige Vertiefung zur Aufnahme des Kontaktstücks 14 zur Vergrößerung der Kontaktfläche mit diesem aufweisen. Das stabförmige Ende 13 des beweglichen Kontakts 11 ist dabei aus dem rohrförmigen Ende 12 des festen Kontaktes 10 herausgezogen. Lediglich ein kleines Stück des stabförmigen Endes 13, in der Figur 2 durch gepunktete Linien angedeutet, verbleibt in dem rohrförmigen Ende 12.In the closed state, an approximately spherical contact piece 14 of the movable contact 11 is in contact with the high-voltage contact 6 and establishes an electrical connection from the high-voltage contact 6 via the movable contact 11 and the fixed contact 10 to the primary winding of the active part 9. The high-voltage contact 6 may have a spherical portion-shaped recess for receiving the contact piece 14 to increase the contact surface with this. The rod-shaped end 13 of the movable contact 11 is pulled out of the tubular end 12 of the fixed contact 10. Only a small piece of the rod-shaped end 13, in the FIG. 2 indicated by dotted lines remains in the tubular end 12th

Im geöffneten Zustand, wie in der Figur 3 gezeigt, ist das stabförmige Ende 13 fast vollständig in das rohrförmige Ende 12 eingeschoben, wie durch die gestrichelten Linien angedeutet. Die Kontaktstücke 14 haben nun einen Abstand vom Hochspannungskontakt 6, die elektrische Verbindung vom Hochspannungskontakt 6 zu den Primärwicklungen der Aktivteile 9 ist damit getrennt. Die Größe des Abstandes hängt dabei von anlagenspezifischen Parametern wie der anliegenden Hochspannung, der Art und dem Druck des verwendeten Isoliergases ab.In the open state, as in the FIG. 3 shown, the rod-shaped end 13 is almost completely inserted into the tubular end 12, as indicated by the dashed lines. The contact pieces 14 now have a distance from the high-voltage contact 6, the electrical connection from the high-voltage contact 6 to the primary windings of the active parts 9 is thus separated. The size of the distance depends on plant-specific parameters such as the applied high voltage, the type and pressure of the insulating gas used.

Oberhalb der Kontaktstücke 14 sind die beweglichen Kontakte 11 durch einen beweglichen Balken als Verbindungselement 15 parallel zur Wicklungsachse 40 verbunden. Senkrecht zu dem Verbindungselement 15 ist eine oder mehrere Schubstangen 16 mit dem Verbindungselement 15 verbunden. Die Schubstange 16 ist mit einer im Weiteren erläuterten Trennmechanik gekoppelt, mittels der die Schubstange 16 senkrecht zur Wicklungsachse 40 bewegbar ist. Die Bewegung der Schubstange 16 wird dabei auf das Verbindungselement 15 übertragen, dieses überträgt die Bewegung auf den beweglichen Kontakt 11.Above the contact pieces 14, the movable contacts 11 are connected by a movable beam as a connecting element 15 parallel to the winding axis 40. Perpendicular to the connecting element 15, one or more push rods 16 is connected to the connecting element 15. The push rod 16 is coupled to a separation mechanism explained below, by means of which the push rod 16 is movable perpendicular to the winding axis 40. The movement of the push rod 16 is transmitted to the connecting element 15, this transmits the movement to the movable contact eleventh

An den senkrechten Schenkeln der Kerne 8 oder an den Rahmen 28 sind Paare von Halteplatten 26 befestigt, die horizontale Verbindungsstege 27 halten. Die Verbindungsstege 27 verlaufen parallel zur Wicklungsachse 40. Die festen Kontakte 10 durchstoßen diese Verbindungsstege 27 und sind in diesen fixiert. Die Schubstange 16 verläuft zwischen jeweils zwei festen Kontakten 10 entweder im Zwischenraum zwischen zwei Verbindungsstegen 27 zwischen diesen hindurch oder durchstößt die Verbindungsstege 27 durch eine Öffnung in diesen. An den Halteplatten 26 oder den Verbindungsstegen 27 können Führungshülsen 30 für die Schubstangen 16 angeordnet sein.On the vertical legs of the cores 8 or on the frame 28 pairs of retaining plates 26 are fixed, the horizontal connecting webs 27 hold. The connecting webs 27 extend parallel to the winding axis 40. The fixed contacts 10 pierce these connecting webs 27 and are fixed in these. The push rod 16 extends between each two fixed contacts 10 either in the space between two connecting webs 27 between them or pierces the connecting webs 27 through an opening in this. On the holding plates 26 or the connecting webs 27 guide sleeves 30 may be arranged for the push rods 16.

Die Figur 4 zeigt einen Ausschnitt aus der Figur 2, wie diese in der Rückansicht, die Figur 5 einen ähnlichen Ausschnitt desselben Messwandlers 1, jedoch gegenüber der Figur 4 in der Vorderansicht. Die Trennmechanik besteht aus einem Getriebe 17, das hier ein Exzentergetriebe ist, und zumindest einer Antriebswelle 22, die mit dem Getriebe 17 gekoppelt ist. Andere Getriebearten, wie beispielsweise ein Trapezgewindegetriebe, sind ebenfalls möglich. Die Antriebswelle 22 ist gasdicht durch eine Gehäusewand nach außen geführt und ist außerhalb des Gehäuses 2 mit dem Antrieb 7 verbunden. In der Gehäusewand sind Lagerbuchsen angeordnet, die um die Antriebswelle 22 angeordnete Lager 25, beispielsweise Kugellager, aufnehmen. O-Ringe zwischen den Lagern 25 stellen die Gasdichtheit her. Die Antriebswelle 22 ist vorzugsweise aus einem elektrisch nichtleitenden Material wie Gießharz hergestellt. Der Antrieb 7 kann beispielsweise ein Handantrieb oder ein elektromotorischer Antrieb sein. Der Antrieb 7 kann auch ein Getriebe enthalten. Durch den Antrieb 7 kann die Antriebswelle 22 in eine rotierende Bewegung versetzt werden. Die Antriebswelle überträgt diese Bewegung auf ein Exzentergetriebe 17, dass die rotierende Bewegung in eine lineare Bewegung umsetzt. Das Exzentergetriebe 17 weist eine Exzenterscheibe 18 und einen Exzenterarm 19 auf. Ein Ende der Antriebswelle 22 ist mit einer Zentralachse 24 der Exzenterscheibe 18 verbunden. Das zweite Ende der Antriebswelle 22 ist mit dem Antrieb 7 verbunden. Exzentrisch zur Zentralachse 24 ist eine Exzenterachse 21 auf der Exzenterscheibe 18 angeordnet. Der Exzenterarm 19 ist mit einem ersten Ende drehbar auf dieser Exzenterachse 21 gelagert. Ein zweites Ende des Exzenterarms 19 ist über einen Koppelstift 20 mit der Schubstange 16 drehbar gekoppelt. Die Schubstange 16 ist durch die Führungshülse 30 auf vertikale Bewegungen beschränkt. Eine mittels des Antriebs 7 auf die Antriebswelle 22 übertragene Rotation wird so auf die Exzenterscheibe 18 übertragen. Der Abstand der Exzenterachse 21 von der Zentralachse 24 bestimmt dabei den möglichen Hub der Schubstange 16 und damit den maximalen Abstand des beweglichen Kontaktes 11 vom Hochspannungskontakt 6. Ausgehend von der in der Figur 4 dargestellten Position wird durch eine Rotation der Exzenterscheibe 18 der Exzenterarm 19 von einer, in der Figur 4 dargestellten, unteren Position in eine obere Position verschoben. Die Exzenterscheibe 18 wird dabei um 180° um die Zentralachse 24 rotiert. Die Exzenterachse rotiert dabei ebenfalls um 180° um die Zentralachse 24 und nimmt den Exzenterarm 19 mit. Da der Exzenterarm 19 mit dem zweiten Ende mit der Schubstange 16 gekoppelt ist, die wiederum auf vertikale Bewegungen beschränkt ist, bleibt währen der Rotation der Koppelstift 20 immer unterhalb der Exzenterachse 21. Die Schubstange 16 wird so nach oben in Richtung Exzenterscheibe 18 bewegt. Die Schubstange 16 überträgt diese vertikale Bewegung über den beweglichen Balken auf die beweglichen Kontakte 11, die dadurch vom Hochspannungskontakt 6 weg bewegt werden. Die elektrische Verbindung zwischen Hochspannungskontakt 6 und beweglichem Kontakt 11 wird dadurch getrennt, somit sind auch die Primärwicklungen von der Hochspannung getrennt. Eine weitere Rotation der Antriebswelle 22, unabhängig davon in welche Richtung, führt zur entgegengesetzten Bewegung der Schubstange 16 und stellt bei einer Drehung um 180° die Verbindung wieder her.The FIG. 4 shows a part of the FIG. 2 like these in the back view, the FIG. 5 a similar section of the same transducer 1, but with respect to the FIG. 4 in the front view. The separation mechanism consists of a gear 17, which is here an eccentric gear, and at least one drive shaft 22 which is coupled to the gear 17. Other types of transmission, such as a trapezoidal thread gear, are also possible. The drive shaft 22 is guided gas-tight through a housing wall to the outside and is outside the housing 2 connected to the drive 7. In the housing wall bearing bushes are arranged, which are arranged around the drive shaft 22 bearing 25, for example, ball bearings record. O-rings between the bearings 25 make the gas-tightness. The drive shaft 22 is preferably made made of an electrically non-conductive material such as cast resin. The drive 7 may be, for example, a manual drive or an electric motor drive. The drive 7 may also include a transmission. By the drive 7, the drive shaft 22 can be placed in a rotating movement. The drive shaft transmits this movement to an eccentric 17, which converts the rotating movement into a linear movement. The eccentric 17 has an eccentric 18 and an eccentric 19. One end of the drive shaft 22 is connected to a central axis 24 of the eccentric disc 18. The second end of the drive shaft 22 is connected to the drive 7. Eccentric to the central axis 24, an eccentric axis 21 is arranged on the eccentric disc 18. The eccentric arm 19 is rotatably mounted with a first end on this eccentric axis 21. A second end of the Exzenterarms 19 is rotatably coupled via a coupling pin 20 with the push rod 16. The push rod 16 is limited by the guide sleeve 30 to vertical movements. A transmitted by means of the drive 7 to the drive shaft 22 rotation is transmitted to the eccentric disc 18. The distance between the eccentric axis 21 of the central axis 24 determines the possible stroke of the push rod 16 and thus the maximum distance of the movable contact 11 from the high-voltage contact 6. Based on the in the FIG. 4 is shown by a rotation of the eccentric disc 18 of the eccentric 19 of a, in the FIG. 4 shown, moved lower position to an upper position. The eccentric disc 18 is rotated by 180 ° about the central axis 24. The eccentric axis also rotates about 180 ° about the central axis 24 and takes the eccentric 19 with. Since the Exzenterarm 19 is coupled to the second end of the push rod 16, which in turn is limited to vertical movements, remains during rotation of the coupling pin 20 always below the eccentric axis 21. The push rod 16 is moved upward in the direction of the eccentric disc 18. The push rod 16 transmits this vertical movement via the movable beam to the movable contacts 11, which are thereby moved away from the high-voltage contact 6. The electrical connection between high voltage contact 6 and movable contact 11 is thereby separated, thus the primary windings are separated from the high voltage. Another rotation of the drive shaft 22, regardless of which direction, leads to the opposite movement of the push rod 16 and restores the connection with a rotation of 180 °.

Die Antriebswelle 22 ist durch eine Halteplatte 26 geführt und mit der Exzenterscheibe 18 durch eine Fehlwinkelausgleichskupplung 23 verbunden. In den Figuren 2 und 4 ist eine Halteplatte 26 zur besseren Darstellung der Trennmechanik nicht dargestellt. Das Exzentergetriebe 17 ist im Bereich unterhalb zweier aneinandergrenzender vertikaler Schenkel benachbarter Kerne 8 angeordnet. Ein Abschirmblech 29 zwischen dem Aktivteil 9 und den vertikalen Schenkeln des zugehörigen Kerns 8 schirmt die Schenkel vor der am Aktivteil 9 anliegenden Hochspannung ab. Die Abschirmbleche 29 sind über die vertikalen Schenkel hinaus weitergeführt und schirmen so auch das Exzentergetriebe 17 und die Halteplatten 26 vor der Hochspannung ab. Die stabförmigen Enden 13 der beweglichen Kontakte 11 sind in den rohrförmigen Enden 12 der festen Kontakte 10 zum Schutz vor Verkantung geführt. Zur reibungsarmen Führung und gleichzeitig zum Herstellen der elektrischen Verbindung zwischen festem Kontakt 10 und beweglichem Kontakt 11 können beispielsweise Lamellenkontakte in dem rohrförmigen Ende 12 angeordnet sein. Die festen Kontakte 10 wirken so als Linearführung für die beweglichen Kontakte 11.The drive shaft 22 is guided by a holding plate 26 and connected to the eccentric disc 18 by a Fehlwinkelausgleichskupplung 23. In the Figures 2 and 4 a holding plate 26 is not shown for better representation of the separation mechanism. The eccentric gear 17 is arranged in the region below two adjacent vertical legs of adjacent cores 8. A shielding plate 29 between the active part 9 and the vertical legs of the associated core 8 shields the legs from the voltage applied to the active part 9 high voltage. The shielding plates 29 are continued beyond the vertical legs and thus also shield the eccentric gear 17 and the holding plates 26 from the high voltage. The rod-shaped ends 13 of the movable contacts 11 are guided in the tubular ends 12 of the fixed contacts 10 for protection against tilting. For low-friction guidance and at the same time for establishing the electrical connection between the fixed contact 10 and the movable contact 11, it is possible, for example, for blade contacts to be arranged in the tubular end 12. The fixed contacts 10 thus act as a linear guide for the movable contacts 11.

In der Figur 5 ist gezeigt, dass der Messwandler 1 zwei Exzentergetriebe 17 aufweist, die jeweils von einer Antriebswelle 22 angetrieben werden. Die Antriebswellen 22 werden durch den Antrieb 7 synchron bewegt. Dies kann in gleicher oder auch in entgegengesetzter Drehrichtung erfolgen. Die Synchronisierung kann im Antrieb 7 durch einen Riemen, eine Kette oder ein Getriebe erfolgen.In the FIG. 5 It is shown that the transducer 1 has two eccentric 17, which are each driven by a drive shaft 22. The drive shafts 22 are moved synchronously by the drive 7. This can be done in the same or in the opposite direction. The synchronization can be done in the drive 7 by a belt, a chain or a gear.

Schubstange 16, Getriebe 17 und Antriebswelle 22 bilden die Verstellmittel, mittels der das Verbindungselement 15 in Stellrichtung 41 bewegt wird.Push rod 16, gear 17 and drive shaft 22 form the adjusting means by means of which the connecting element 15 is moved in the direction of adjustment 41.

Vorzugsweise werden das Exzentergetriebe 17 und die Halteplatten 26 durch einen hochfesten Werkstoff wie Stahl gefertigt. Die Schubstangen 16, das Verbindungselement 15, der Verbindungssteg 27 und die Führungshülsen 30 sind vorzugsweise aus einem elektrisch nichtleitenden Werkstoff wie Kunststoff beispielsweise Polyoxymethylen, das hohen Steifigkeit, niedrigen Reibwerte und ausgezeichneten Dimensionsstabilität und thermischen Stabilität aufweist, gefertigt.Preferably, the eccentric 17 and the holding plates 26 are made by a high strength material such as steel. The push rods 16, the connecting element 15, the connecting web 27 and the guide sleeves 30 are preferably made of an electrically non-conductive material such as plastic, for example polyoxymethylene, which has high rigidity, low friction and excellent dimensional stability and thermal stability.
