Unterhalb der Leistungsschaltstellen ist am Polrahmen ein Antrieb befestigt, der über ein Getriebe auf alle drei Schaltstellen wirkt.

DARSTELLUNG DER ERFINDUNGPRESENTATION OF THE INVENTION

Der Erfindung, wie sie in den Patentansprüchen angegeben ist, liegt die Aufgabe zugrunde, eine Hochstromschaltanordnung zum Einbau in eine Generatorableitung zu schaffen, die sich durch einen geringen Platzbedarf auszeichnet und die zugleich in einfacher Weise gefertigt und in die Ableitung eingebaut werden kann.The invention, as indicated in the claims, the object is to provide a high-current switching arrangement for installation in a generator lead, which is characterized by a small footprint and can be manufactured at the same time in a simple manner and installed in the discharge.

Gemäss der vorliegenden Erfindung wird eine Hochstromschaltanordnung bereitgestellt zum Einbau in eine zwischen einem Generator und einem Transformator angeordnete ausgeführte Generatorableitung. Diese Hochstromschaltanordnung enthält einen auf einer Standfläche positionierbaren, Polrahmen, einen am Polrahmen befestigten Schalterpol eines Generatorschalters und einen am Polrahmen befestigten Antrieb. Der Schalterpol weist ein der Führung und Unterbrechung hoher Ströme dienendes und eine Leistungsschaltstelle enthaltendes Aktivteil auf mit zwei in axialer Richtung mit Abstand voneinander gehaltenen Stromanschlüssen zur elektrisch leitenden Integration des Aktivteils beim Einbau der Hochstromschaltanordnung in den Leiterzug eines hochspannungsführenden Stromleiters der Generatorableitung.According to the present invention, a high current switching arrangement is provided for installation in a generator lead arranged between a generator and a transformer. This high-current switching arrangement includes a pole frame which can be positioned on a standing surface, a pole of a generator switch fastened to the pole frame and a drive fixed to the pole frame. The switch pole has one of the leadership and interruption of high currents serving and a power switching point containing active part with two axially spaced from each other power connections for electrically conductive integration of the active part when installing the high-current switching arrangement in the Leiterzug a high-voltage conductor of the generator output.

Der Antrieb ist an einer ersten zweier quer zur Achse ausgerichteter Stirnseiten des Polrahmens angeordnet. Ein Kraft vom Antrieb auf die Leistungsschaltstelle übertragendes Getriebe ist durch die erste Stirnseite des Polrahmens hindurch an das Aktivteil geführt.The drive is arranged on a first two transversely aligned to the axis end faces of the pole frame. A power from the drive to the power switching point transmitting gear is passed through the first end of the pole frame to the active part.

Da bei der Hochstromschaltanordnung nach der Erfindung nun kein Platz seitlich der Generatorableitung resp. der Hochstromschaltanordnung benötigt wird, können bei einer mehrphasigen Hochstromschaltanordnung die einzelnen Schalterpole raumsparend nebeneinander aufgestellt werden. Zudem können nun die Schalterpole in wirtschaftlich vorteilhafter Weise baugleich ausgebildet sein.Since in the high-current switching arrangement according to the invention now no space side of the generator lead, respectively. the high current switching arrangement is required, the individual switch poles can be placed next to each other in a space-saving manner in a multi-phase high current switching arrangement. In addition, the switch poles can now be of identical construction in an economically advantageous manner.

Bei einer Ausführungsform der Hochstromschaltanordnung ist der Antrieb unterhalb des Stromanschlusses angebracht. Er befindet sich daher nach Einbau der Hochstromschaltanordnung in die Generatorableitung unter dem Stromleiter der Generatorableitung. Er benötigt daher keinen zusätzlichen Platz auf der Standfläche und ist damit einfach zugänglich, beispielsweise im Fall einer Wartung.In one embodiment of the high current switching arrangement, the drive is mounted below the power connector. He is therefore after installation of the high-current switching arrangement in the generator lead under the conductor the generator derivation. It therefore requires no additional space on the stand and is therefore easily accessible, for example in the case of maintenance.

Enthält die Hochstromschaltanordnung ein das Aktivteil aufnehmendes, kastenförmigen Gehäuse mit zwei Gehäuseöffnungen, die in Seiten des Gehäuses eingeformt sind, welche einander gegenüberliegen, und durch welche der hochspannungsführender Stromleiter der Generatorableitung führbar ist, dann befindet sich der Antrieb unterhalb einer ersten der beiden Gehäuseöffnungen und ist das Getriebe an das im Inneren des Gehäuses angeordnete Aktivteil geführt. Wegen der dann berührungsgeschützten Ausführung von Hochstromschaltanordnung und Generatorableitung kann dann der Antrieb während des Betriebs der Generatorableitung überprüft werden.If the high-current switching arrangement includes a box-shaped housing accommodating the active part, with two housing openings formed in sides of the housing facing each other and through which the high voltage-carrying current conductor of the generator lead can be led, then the drive is below a first of the two housing openings the gear is guided to the arranged in the interior of the housing active part. Because of the then touch-protected design of high-current switching arrangement and generator discharge then the drive can be checked during operation of the generator lead.

Um die Montage und Wartung der Hochstromschaltanordnung zu erleichtern, kann zumindest ein Teil des Bodens des Gehäuses lösbar mit dem Polrahmen verbunden sein und kann dieser Teil eine Montageöffnung verschliessen, die nach Aufstellen der Hochstromschaltanordnung und Öffnen der Montageöffnung von der Standfläche aus den Zugang ins Innere des Gehäuses ermöglicht. Hierbei können in den Polrahmen eingeformte Standbeine den Zugang zur Montageöffnung erleichtern, da sie den Abstand zwischen Standfläche und Montageöffnung vergrössern. Der vergrösserten Abstand verbessert zugleich die Zufuhr von Frischluft, die zur Kühlung des bei Betrieb der Hochstromschaltanordnung erwärmten Aktivteils verwendet werden kann. Die Kühlwirkung der zwischen Standfläche und Gehäuseboden zugeführten Frischluft ist besonders gross, wenn der Gehäuseboden rasterförmig gelocht ist. Die Frischluft kann daher von unten ins Gehäuse eintreten und im Inneren des Gehäuses Wärme aufnehmen. Die erwärmte Luft kann über Öffnungen, die in der Decke des Gehäuses angeordnet sind, infolge thermischer Konvektion aus dem Gehäuse entfernt werden.In order to facilitate the assembly and maintenance of the high current switching arrangement, at least a part of the bottom of the housing can be releasably connected to the pole frame and this part can close a mounting opening, which after setting up the high current switching arrangement and opening the mounting hole from the stand from the inside Housing allows. In this case, molded legs in the pole frame can facilitate access to the mounting hole, as they increase the distance between the base and mounting hole. The increased distance also improves the supply of fresh air that can be used to cool the heated during operation of the high-current switching device active part. The cooling effect of supplied between the base and the housing bottom fresh air is particularly large when the housing bottom is perforated grid-shaped. The fresh air can therefore enter from below into the housing and absorb heat inside the housing. The heated air can be removed from the housing via openings located in the ceiling of the housing due to thermal convection.

Eine gegen Beschädigungen geschützte und dennoch leicht zugängliche Kraftübertragung vom Antrieb auf die Leistungsschaltstelle kann erreicht werden, wenn das Getriebe einen an einem feststehenden Drehpunkt schwenkbar gelagerten, zweiarmigen Umlenkhebel aufweist sowie zwei Schubstangen, von denen die erste mit einem erste Ende an einen ersten Arm des Umlenkhebels und mit einem zweiten Ende an einen Hebel angelenkt ist, der starr mit einer von unten an die Leistungsschaltstelle geführten Isolierwelle verbunden ist, und von denen die zweite mit einem erste Ende an den zweiten Arm des Umlenkhebels und mit einem zweiten Ende an ein axial verschiebbar durch den Polrahmen hindurch geführtes Antriebselement des Getriebes angelenkt ist.A protected against damage and yet easily accessible power transmission from the drive to the power switching point can be achieved when the transmission has a pivotally mounted on a fixed pivot point, two-armed lever and two push rods, from to which the first is hinged with a first end to a first arm of the reversing lever and a second end to a lever which is rigidly connected to a guided from below to the power switching point insulating shaft, and of which the second with a first end to the second Arm of the reversing lever and is articulated with a second end to an axially displaceable guided through the pole frame drive element of the transmission.

Da nach Einbau der Hochstromschaltanordnung in die Generatorableitung die beiden Stirnseiten des Polrahmens praktisch vollständig unter der berührungsgeschützten Generatorableitung liegen, werden keine zusätzliche Standfläche und zusätzlicher Platz für Montage- und Wartungsarbeiten benötigt, wenn an der ersten Stirnseite des Polrahmens mindestens ein weiterer Antriebe angeordnet ist, der kraftschlüssig mit einem im Gehäuse angeordneten, als Trenn- Erdungs- oder Anfahrschalter der Hochstromschaltanordnung ausgebildeten Schaltgerät verbunden ist.Since after installation of the high-current switching arrangement in the generator lead the two end faces of the pole frame are practically completely under the touch-protected Generatorableitung, no additional footprint and additional space for assembly and maintenance are needed if at least one other drives is arranged on the first end face of the pole frame, the non-positively connected to a housing disposed in the form of separation grounding or starting switch of the high current switching device switching device is connected.

Bei bestimmten Standorten der Hochstromschaltanordnung kann es vorteilhaft sein, wenn auf einer der ersten Stirnseite gegenüberliegenden zweiten Stirnseite des Polrahmens der vorgenannte mindestens eine weiterer Antrieb angeordnet ist.In certain locations of the high-current switching arrangement, it may be advantageous if the aforementioned at least one further drive is arranged on a second end face of the pole frame opposite the first end face.

Ist die Hochstromschaltanordnung mehrphasig ausgebildet, so ist es aus Gründen einer auf der baugleichen Ausbildung der Schalterpole basierenden Fertigung und einer dementsprechend vereinfachten Montage häufig am wirtschaftlichsten, wenn der Polrahmen lediglich einen einzigen (einphasig gekapselten) Schalterpol trägt.If the high-current switching arrangement is designed to be multi-phase, then it is often the most economical for the sake of a construction based on the identical design of the switch poles and a correspondingly simplified installation, if the pole frame carries only a single (single-phase encapsulated) Schalterpol.

Je nach Anforderung an die Hochstromschaltanordnung kann es vorteilhaft sein, wenn der Polrahmen mindestens zwei Schalterpole trägt. Es kann dann an einer der beiden Stirnseiten des Polrahmen ein einziger Antrieb angeordnet sein, der über ein einziges Getriebe Kraft auf die Schalterpole überträgt.Depending on the requirements of the high current switching arrangement, it may be advantageous if the pole frame carries at least two switch poles. It can then be arranged on one of the two end faces of the pole frame, a single drive, which transmits power to the switch poles via a single gear.

This arrangement can be installed in a contact-protected generator lead GA, which is guided by a generator G to a high-voltage transformer TR. In Fig.1 is shown only for the phase T of generally designed as a metal tube and a centrally guided in the phase conductor phase contact protection of the generator lead GA.

Da die drei Schalterpole des Generatorschalters weitgehend identisch ausgebildet sind, wird lediglich einer der Schalterpole, nämlich der Schalterpol R genauer beschrieben. Dieser Schalterpol sitzt fest auf einem von den übrigen Schalterpolen S und T getrennten, rechteckig ausgebildeten metallenen Polrahmen 10 auf. Der Schalterpol enthält ein aus Fig.2 ersichtliches, längs einer Achse A erstrecktes Aktivteil 20, das mit Hilfe eines aus Fig.2 ersichtlichen Stützisolators 21 an einer in den Polrahmen 10 integrierten Traverse befestigt ist und das dem Führen und Unterbrechen hoher Ströme dient. Nach Einbau der Hochstromschaltanordnung in die Generatorableitung GA bildet dieses Aktivteil einen Abschnitt des zur Führung hoher Ströme geeigneten Stromleiters der Generatorableitung GA. Zudem enthält dieses Aktivteil eine nicht ersichtliche, mechanisch betätigbare Leistungsschaltstelle, die einen den Generator G und den Transformator TR enthaltenden Stromkreis öffnen oder schliessen kann, sowie zwei aus Fig.2 ersichtliche Stromanschlüsse 23, 24. Diese beiden Stromanschlüsse sind in axialer Richtung mit Abstand voneinander gehalten und dienen der elektrisch leitenden Integration des Aktivteils 20 beim Einbau der Hochstromschaltanordnung in den Leiterzug des hochspannungsführenden Stromleiters der Generatorableitung GA.Since the three switch poles of the generator switch are formed substantially identical, only one of the switch poles, namely the switch pole R is described in more detail. This switch pole sits firmly on one of the other switch poles S and T separated, rectangular metal pole frame 10. The switch pole contains an off Fig.2 apparent, along an axis A extending active part 20, by means of a Fig.2 apparent support insulator 21 is attached to a built-in pole frame 10 Traverse and serves to guide and interrupting high currents. After installation of the high-current switching arrangement in the generator lead GA this active part forms a portion of the suitable for guiding high currents conductor of the generator lead GA. In addition, this active part contains an unillustrated, mechanically actuated power switching point, which can open or close a circuit containing the generator G and the transformer TR, as well as two Fig.2 apparent power connections 23, 24. These two power connections are held in the axial direction with distance from each other and serve the electrically conductive integration of the active part 20 during installation of the High current switching arrangement in the conductor of the high-voltage-carrying conductor of the generator lead GA.

Das Aktivteil ist in einem den Berührungsschutz der Hochstromschaltanordnung sicherstellenden, kastenförmigen, im allgemeinen aus Metallblech geformten Gehäuse 30 angeordnet. Dieses Gehäuse ist auf dem Polrahmen 10 befestigt und weist zwei Öffnungen auf. Diese Öffnungen sind in Seiten des Gehäuses 30 eingeformt, welche einander gegenüberliegen und im wesentlichen senkrecht zur Achse A ausgerichtet sind. In die nach vorne weisende Seite 31 ist eine erste 32 der beiden Öffnungen eingeformt. Diese Öffnung dient der Durchführung eines mit dem Transformator TR verbindbaren Abschnitts der nicht dargestellten Phase R der Generatorableitung. Die nicht ersichtliche andere der zwei Öffnungen dient der Durchführung eines mit dem Generator G verbindbaren Abschnitts der nicht dargestellten Phase des hochspannungsführenden Stromleiters der Generatorableitung GA.The active part is arranged in a box-shaped, generally formed from sheet metal housing 30 ensuring the contact protection of the high current switching arrangement. This housing is mounted on the pole frame 10 and has two openings. These openings are formed in sides of the housing 30, which are opposite each other and are aligned substantially perpendicular to the axis A. In the forward-facing side 31, a first 32 of the two openings is formed. This opening serves to carry out a connectable to the transformer TR portion of the phase R, not shown, of the generator lead. The non-apparent other of the two openings is used to carry out a connectable to the generator G portion of the phase, not shown, of the high-voltage-carrying conductor of the generator lead GA.

Beim Einbau der Hochstromschaltanordnung in die Generatorableitung GA werden die Aktivteile 20 der auf den Polrahmen 10 ruhenden Schalterpole R, S und T phasenweise mit den ins Gehäuse 30 geführten Abschnitten des Stromleiters der Generatorableitung GA verbunden. Berührungsschutz wird durch die in Fig.1 lediglich für die Phase T dargestellten beiden Abschnitte des Metallrohrs und das Gehäuse 30 erreicht, welches etwa durch Schweissen mit den beiden Rohrabschnitten elektrisch leitend verbunden wird, und welches wie die beiden Rohrabschnitte im allgemeinen mit Luft gefüllt ist.When installing the high-current switching arrangement in the generator lead GA, the active parts 20 of resting on the pole frame 10 switch poles R, S and T are connected in phases with the guided into the housing 30 sections of the conductor of the generator lead GA. Contact protection is ensured by the in Fig.1 achieved only for the phase T shown two sections of the metal tube and the housing 30, which is electrically connected, for example by welding with the two pipe sections, and which is like the two pipe sections generally filled with air.

Zur Betätigung der Schaltstelle ist ein mechanischer Antrieb 40 vorgesehen, der an einer dem Transformator TR zugewandten Stirnseite 11 des Polrahmens 10 unterhalb der Öffnung 32 angeordnet ist. Dieser Antrieb ist mit einem aus Fig.2 ersichtlichen Getriebe 50 verbunden, welches durch die Stirnseite 11 des Polrahmens 10 hindurch an das Aktivteil 20 und damit zur Leistungsschaltstelle geführt ist. Das Getriebe weist einen an einem feststehenden Drehpunkt 51 schwenkbar gelagerten, zweiarmigen Umlenkhebel 52 auf sowie zwei Schubstangen 53 und 54. Die Schubstange 53 ist mit einem Ende an einen Arm des Umlenkhebels 52 und mit dem anderen Ende an einen Hebel 55 angelenkt, der starr mit einer von unten ins Aktivteil 20 geführten, die Leistungsschaltstelle des Aktivteils steuernden Isolierwelle 22 verbunden ist. Die Schubstange 54 ist mit einem ihrer beiden Ende an den anderen Arm des Umlenkhebels 52 und mit ihrem zweiten Ende an ein parallel zur Achse A verschiebbares, durch die Stirnseite 11 des Polrahmens 10 hindurch geführtes Antriebselement 56 des Getriebes 50 angelenkt.To actuate the switching point, a mechanical drive 40 is provided, which is arranged on a transformer TR facing end face 11 of the pole frame 10 below the opening 32. This drive is with one out Fig.2 apparent gear 50 is connected, which is guided through the end face 11 of the pole frame 10 through to the active part 20 and thus to the power switching point. The transmission has a pivotally mounted on a fixed pivot point 51, two-armed lever 52 and two push rods 53 and 54. The push rod 53 is hinged at one end to an arm of the bell crank 52 and the other end to a lever 55 which is rigid with one guided from below into the active part 20, the power switching point the active part controlling insulating shaft 22 is connected. The push rod 54 is articulated with one of its two ends to the other arm of the reversing lever 52 and with its second end to a parallel to the axis A displaceable, guided through the end face 11 of the pole frame 10 drive element 56 of the transmission 50.

Aus Fig.2 ist ersichtlich, dass das Innere des Gehäuses 30 durch rasterförmig gelochte, im allgemeinen metallene Abdeckplatten abgeschlossen ist, welche den Boden 33 des Gehäuse 30 bilden. Die Abdeckplatten sind lösbar mit der Unterseite des Polrahmens 10 verbunden und stellen den Berührungsschutz auf der Unterseite des Schalterpols R sicher.Out Fig.2 It can be seen that the interior of the housing 30 is closed by grid-shaped, generally metal cover plates which form the bottom 33 of the housing 30. The cover plates are detachably connected to the underside of the pole frame 10 and provide the contact protection on the bottom of the switch pole R safe.

Bei Betrieb der Hochstromschaltanordnung erwärmt sich ein das Aktivteil 20 enthaltender und im Gehäuse 30 angeordneter Abschnitt des Stromleiters der Generatorableitung GA. Die Lochrasterung gewährleistet, dass kühle Luft von unten, d.h. zwischen einer Standfläche SF und dem Gehäuseboden 33, ins Innere des Gehäuses 30 eintreten und für eine Kühlung des Stromleiters sorgen kann. Da die gelochten Abdeckplatten lösbar mit dem Polrahmen 10 verbunden sind, verschliessen sie zugleich eine Montageöffnung 34. Nach Aufstellen der Hochstromschaltanordnung auf der Standfläche SF und Entfernen eines Teils der Abdeckplatten resp. eines Teils des Gehäusebodens 33 ermöglicht die Montageöffnung von der Standfläche SF aus den Zugang ins Innere des Gehäuses 30. Aus Fig.1 ersichtliche, in den Polrahmen 10 eingeformte Standbeine 12 verbessern den Zugang zur Montageöffnung 34.During operation of the high-current switching arrangement, a portion of the current conductor of the generator lead GA containing the active part 20 and arranged in the housing 30 heats up. The perforated grid ensures that cool air from below, ie between a footprint SF and the housing bottom 33, can enter the interior of the housing 30 and provide cooling for the conductor. Since the perforated cover plates are detachably connected to the pole frame 10, they also close a mounting hole 34. After setting up the high-current switching arrangement on the footprint SF and removing a portion of the cover plates resp. a portion of the housing bottom 33 allows the mounting opening from the footprint SF from access to the interior of the housing 30. Off Fig.1 visible, molded into the pole frame 10 legs 12 improve access to the mounting hole 34th

Da der Antrieb 40 unterhalb der Öffnung 32 und damit auch unterhalb der berührungsgeschützten Generatorableitung GA angeordnet ist, benötigt er keinen zusätzlichen Platz auf der Standfläche SF und kann wegen der berührungsgeschützten Ausführung von Hochstromschaltanordnung und Generatorableitung GA während des Betriebs der Generatorableitung überprüft werden. Da nun kein Platz seitlich der Generatorableitung resp. der Hochstromschaltanordnung benötigt wird, können die einzelnem Schalterpole R, S, T eng nebeneinander aufgestellt werden. Zudem können nun die einzelnen Schalterpole in wirtschaftlich vorteilhafter Weise identisch ausgebildet sein.Since the drive 40 is arranged below the opening 32 and thus also below the contact-protected generator lead GA, it does not require additional space on the footprint SF and can be checked because of the touch-protected design of high current switching arrangement and generator lead GA during operation of the generator lead. Since now no space at the side of the generator lead, respectively. the high current switching arrangement is required, the individual switch poles R, S, T can be placed close to each other. In addition, the individual switch poles can now be formed identically in an economically advantageous manner.

Aus den Figuren 1 und 2 ist ersichtlich, dass an der Stirnseite 11 des Polrahmens 10 drei weitere Antriebe 41 angebracht sind. Diese Antriebe 41 sind jeweils über ein nicht dargestelltes Getriebe kraftschlüssig mit einem im Gehäuse angeordneten, als Trenn-, Erdungs- oder Anfahrschalter der Hochstromschaltanordnung ausgebildeten Schaltgerät verbunden, das neben dem die Leistungsschaltstelle enthaltenden Aktivteil 20 im Gehäuse 30 des Schalterpols R angeordnet ist. Da auch diese Antriebe während des Betriebs der Hochstromschaltanordnung unterhalb der berührungsgeschützten Generatorableitung GA liegen, beanspruchen auch diese Antriebe keine zusätzliche Standfläche S und können während des Betriebs der Hochstromschaltanordnung überprüft und gegebenenfalls auch gewartet werden.From the Figures 1 and 2 it can be seen that 10 three further drives 41 are mounted on the end face 11 of the pole frame. These drives 41 are each frictionally connected via an unillustrated transmission with a arranged in the housing, designed as a disconnector, grounding or starting switch the high-current switching device switching device, which is arranged in addition to the power switching point containing active part 20 in the housing 30 of the switch pole R. Since these drives during operation of the high-current switching arrangement are below the contact-protected generator discharge GA, these drives require no additional footprint S and can be checked during operation of the high-current switching arrangement and optionally also maintained.

Je nach Zugänglichkeit der Hochstromschaltanordnung kann der Antrieb 40 resp. können die Antriebe 40 und 41 auch auf der dem Generator G zugewandten Stirnseite des Polrahmens 10 angeordnet sein.Depending on the accessibility of the high-current switching arrangement, the drive 40 resp. For example, the drives 40 and 41 may also be arranged on the end face of the pole frame 10 facing the generator G.

Weist die Hochstromschaltanordnung neben dem Antrieb 40 auch mindestens einen der Antriebe 41 auf, so kann an einer der beiden Stirnseiten des Polrahmens 10 der Antrieb 40 und an der (dieser Stirnseite gegenüberliegenden) anderen Stirnseite der mindestens eine Antrieb 41 angeordnet sein.If the high-current switching arrangement has not only the drive 40 but also at least one of the drives 41, the drive 40 can be arranged on one of the two end faces of the pole frame 10 and the at least one drive 41 on the other end face (opposite this end face).

Ist die Hochstromschaltanordnung mehrphasig ausgebildet, so ist es im allgemeinen am wirtschaftlichsten, wenn der Polrahmen 10 lediglich einen einzigen (einphasig gekapselten) Schalterpol R, S oder T trägt. Die Schalterpole und die jedem der Schalterpole zugeordneten Antriebe und Getriebe können dann in kostengünstiger Weise baugleich gefertigt und dementsprechend einfacher Weise montiert und gewartet werden.If the high current switching arrangement is designed to be multi-phase, it is generally most economical if the pole frame 10 carries only a single (single-phase encapsulated) switch pole R, S or T. The switch poles and each of the switch poles associated drives and gearbox can then be made identical in cost-effective manner and accordingly mounted and maintained in a simple manner.

Je nach Anforderung an die Hochstromschaltanordnung kann es gegebenenfalls vorteilhaft sein, wenn der Polrahmen 10 mindestens zwei Schalterpole R, S, T trägt. Bei einer solchen Ausführungsform der Hochstromschaltanordnung kann dann an einer, z. B. 11, der beiden Stirnseiten des Polrahmen 10 ein einziger Antrieb vorgesehen sein, der über ein einziges Getriebe Kraft auf die mindestens zwei Schalterpole überträgt.Depending on the requirements of the high current switching arrangement, it may be advantageous if the pole frame 10 carries at least two switch poles R, S, T. In such an embodiment of the high-current switching arrangement can then at a, z. B. 11, the two end faces of the pole frame 10 may be provided a single drive, which transmits power via a single gear on the at least two switch poles.

Für bestimmten Anwendungen kann die Hochstromschaltanordnung auch ohne Berührungsschutz ausgebildet sein. Auch bei dieser Ausführungsform der Hochstromschaltanordnung nach der Erfindung wird für den Antrieb nach Einbau in die Generatorableitung keine zusätzliche Standfläche benötigt, da sich dann ja der Antrieb ebenfalls unmittelbar unter Generatorableitung befindet.For certain applications, the high current switching arrangement may also be designed without contact protection. Also in this embodiment of the high-current switching arrangement according to the invention, no additional footprint is required for the drive after installation in the generator lead, since then yes the drive is also directly below the generator lead.
