Definitions
- the invention relates to a gas-insulated switchgear assembly with a gas-filled container and a multi-pole vacuum switch arranged in the container with the horizontal position of its vacuum interrupters and with a multi-pole three-position switch disconnector arranged with the horizontal position of its switch shaft below the vacuum switch and drive devices for the vacuum switch arranged on a front wall of the container and the load-break switch, furthermore with feedthrough bushings arranged below the load-break switch on the front wall.
- a switchgear of this type has become known from DE-A-39 15 948. This arrangement provides favorable conditions for making the electrical connections between the vacuum switch and the load break switch. Likewise, the busbars can be conveniently installed, which enter and exit on the side walls of the container and can therefore be inserted directly into adjoining switch panels.
- vacuum interrupters are arranged with longitudinal axes oriented at right angles to the front wall of the container and that the switch-disconnector is arranged with an axis of rotation that is likewise horizontal, but aligned parallel to the front wall of the container.
- busbar bushings in the side walls of the container can be dispensed with without disadvantage.
- These bushings can also be arranged on the front wall of the container and connected to the switch disconnector without crossing.
- the containers of a multi-panel switchgear can then be set up next to one another without lateral spacing, the busbars being able to be laid in a suitable manner in front of the containers and being adaptable if necessary.
- the load-break switch can be actuated by an inner pivoting lever which interacts with its switch shaft and which, on its end facing the front wall of the container, engages an outer, has a fork opening against the front wall, sealed gas-tight.
- FIG. 1 shows a section of a medium-voltage switchgear with a vacuum circuit breaker and a three-position switch-disconnector, as well as the associated drive devices and the electrical feedthroughs.
- FIG. 2 shows the side-by-side arrangement of three vacuum interrupters of the vacuum circuit breaker according to FIG. 1. Only the middle of three upper insulating plates is shown to make the parts underneath visible.
- the control panel 1 shown in the figures has a closed container 2 made of sheet steel, which comprises a vacuum circuit breaker, designated as a whole as 3, with a drive device 4 and a three-position switch disconnector 5 with an associated further drive device 6.
- the container 2 is grounded during operation and contains a suitable insulating gas, for example sulfur hexafluoride (SF6).
- SF6 sulfur hexafluoride
- the vacuum circuit breaker 3 has a three-pole design and accordingly has three vacuum interrupters 12, which can each be actuated by the drive device 4 for switching on and off by means of a coupling device 14 constructed in a straight line and passing through a front wall 13 of the container 1.
- the three vacuum interrupters 12 lie next to one another with a horizontal longitudinal axis and are fastened between insulating plates in a manner still to be explained.
- the load break switch 5 arranged below the vacuum circuit breaker 3 is arranged with an axis of rotation running parallel to the front wall 13 of the container 2.
- the three poles of the load-break switch 5 are therefore one behind the other in FIG. 1, as are the three vacuum interrupters 12. Therefore, the connections between the two switches can be easily made without crossing busbars 15 provided for this purpose.
- feeder busbars 16 are laid vertically between the bushings 11 and the vacuum interrupters 12 without crossing.
- the bushings 11 are arranged in steps in height in order to facilitate the connection of busbars.
- the busbars can be connected from the front without having to have access to the interior of the container.
- each vacuum interrupter 12 is assigned an upper insulating plate 17, which are fastened to angular holding members 20.
- the holding members 20 are attached to the front wall 13 and an opposite rear wall 21 of the container 2.
- a rear carrier 22 and a front carrier 23 are connected to each upper insulating plate 17, between which the vacuum interrupter is arranged.
- Insulating plate 17 with the brackets 22 and 23 and the vacuum interrupter 12 form a non-functional, but mechanically coherent and mountable unit which, as long as the container 2 is still open, can be easily hung and fastened to the holding members 20.
- Another component of the circuit breaker 3 are two lower insulating plates 24 and 25 which extend transversely to the upper insulating plates 17 and which, like this, are fastened to holding members 26 which in turn are fastened to the walls of the container 2.
- the insulating plate 24 is common for the rear ends of the vacuum interrupters 12 connected to the carriers 22, while the insulating plate 25 is common for the front ends of the vacuum interrupters 12 connected to the carriers 23.
- This arrangement of the insulating plates 17, 24 and 25 leads to a good stiffening against the high forces which short-circuit currents can cause due to the relatively small distances between the vacuum interrupters in the insulating gas, while at the same time the circulation of the insulating gas in the container 2 in the region of the vacuum interrupters 12 is less hindered than when using a single lower insulating plate.
- the lower holding members 26 are expediently attached to opposite side walls 28 and 29 of the container 2. If a common lower insulating plate is used instead of the individual lower insulating plates 24 and 25, a different arrangement of the holding members 26 is also possible, for example both on the rear wall 21 and on the side walls 28 and 29. It is also recommended to use one for all vacuum interrupters 12 common lower insulating plate to be dimensioned so that it is just like the lower right Insulating plate 25 does not protrude significantly beyond the connecting device 30 in the direction of the front wall 13, so that the elements of the coupling device 14 are easily accessible from below during assembly and the insulating gas can circulate.
- connecting rails 27 are provided, which are led out through openings in the lower insulating plates 24 and connected there to the busbars 16.
- the front lower insulating plates 25 each carry a connection device 30 for the busbars 15 and a flexible current band 31, which establishes the electrical connection with the movable connecting bolt 32 of the vacuum interrupter 12.
- each of the vacuum interrupters 12 is connected to the drive device 4 by a coupling device 14.
- a clamping device 33, an insulating body 34 and an actuating rod 35 in connection with a bellows 36 are provided as components of the coupling device 14.
- the bellows 36 is fastened at one end in the front wall 13 of the container 2 and at its opposite end, which projects into the container 2, is connected to the actuating rod 35.
- a lever gear 37 is connected to the end of the actuating rod 35 which is accessible on the outside of the container 2 and to which a tension spring 40 serving as a contact force spring and as an opening spring belongs.
- the lever mechanism can preferably have the structure described in DE-A-34 14 016.
- the lever gears 37 corresponding to the number of poles are acted upon by the drive device 4 with a driving force in a known manner in order to switch on the vacuum interrupters.
- the drive device 4 is unlatched, whereupon the tension spring 40 acts as a switch-off spring and can switch off the vacuum interrupters 12 against the gas pressure existing in the container.
- control panel 1 includes a three-position switch-disconnector 5, for example of the type according to DE-C-33 04 272.
- the circuit-breaker 3 and the load-break switch 5 can be selected in particular in accordance with DE-A-39 15 949 be able to control short-circuit currents without interlocking the circuit breaker and the load break switch.
- a common for all poles of the load break switch 5 switch shaft 41 is arranged horizontally and parallel to the front wall 13 of the container 2.
- the drive device 6 for the switch disconnector 5 works with the switch shaft 41 by means of a further coupling device, designated as a whole as 42, which is designed such that the installation of the switch disconnector 5 in the container 2 can be carried out with little effort.
- the coupling device 42 as is known per se, has a bellows 43, which is fastened with one end in a gas-tight manner in the front wall 13 of the container 2.
- the bellows 43 is not used to initiate a linear movement, but rather a pivoting movement.
- an outer pivot lever 44 the pivot bearing of which is arranged approximately in the plane of the front wall 13.
- a driver bolt 45 for a fork opening 46 of an inner pivot lever 47 which is mounted approximately centrally on a bearing bolt 50.
- a reversing gear 51 the switch shaft 41.
- the inner pivot lever 47 and the deflecting gear 51 are expediently attached to the load-break switch 5 in such a way that this unit can be coupled to the outer pivot lever 44 and thus to the drive device 6 for the load-break switch 5 by simply sliding the fork opening 46 onto the driving pin 45. Adjustment and adjustment work can largely be dispensed with.

Description
Die Erfindung betrifft eine gasisolierte Schaltanlage mit einem gasgefüllten Behälter und einem in dem Behälter mit horizontaler Lage seiner Vakuumschaltröhren angeordneten mehrpoligen Vakuumschalter sowie mit einem mit horizontaler Lage seiner Schalterwelle unterhalb des Vakuumschalters angeordneten mehrpoligen Dreistellungs-Lasttrennschalter und an einer Frontwand des Behälters angeordneten Antriebsvorrichtungen für den Vakuumschalter und den Lasttrennschalter, ferner mit unterhalb des Lasttrennschalters an der Frontwand angeordneten Abgangsdurchführungen.The invention relates to a gas-insulated switchgear assembly with a gas-filled container and a multi-pole vacuum switch arranged in the container with the horizontal position of its vacuum interrupters and with a multi-pole three-position switch disconnector arranged with the horizontal position of its switch shaft below the vacuum switch and drive devices for the vacuum switch arranged on a front wall of the container and the load-break switch, furthermore with feedthrough bushings arranged below the load-break switch on the front wall.
Eine Schaltanlage dieser Art ist durch die DE-A-39 15 948 bekanntgeworden. Bei dieser Anordnung ergeben sich günstige Bedingungen für die Anbringung der elektrischen Verbindungen zwischen dem Vakuumschalter und dem Lasttrennschalter. Ebenso sind die Sammelschienen günstig verlegbar, die an den Seitenwänden des Behälters ein- und austreten und daher unmittelbar in seitlich anschließende Schaltfelder einführbar sind.A switchgear of this type has become known from DE-A-39 15 948. This arrangement provides favorable conditions for making the electrical connections between the vacuum switch and the load break switch. Likewise, the busbars can be conveniently installed, which enter and exit on the side walls of the container and can therefore be inserted directly into adjoining switch panels.
Es zeigt sich jedoch, daß die mechanischen Verbindungen zwischen den an der Frontwand des Behälters befindlichen Antriebsvorrichtungen und den durch diese zu betätigenden Schaltgeräten verhältnismäßig kompliziert sind. Der Erfindung liegt die Aufgabe zugrunde, ohne Nachteil für die elektrischen Verbindungen den mechanischen Aufbau der Antriebsverbindungen zu vereinfachen.It turns out, however, that the mechanical connections between the drive devices located on the front wall of the container and the switching devices to be actuated by them are relatively complicated. The invention has for its object to simplify the mechanical structure of the drive connections without disadvantage for the electrical connections.
Diese Aufgabe wird gemäß der Erfindung dadurch gelöst, daß die Vakuumschaltröhren mit rechtwinklig zur Frontwand des Behälters ausgerichteten Längsachsen angeordnet sind und daß der Lasttrennschalter mit gleichfalls horizontaler, jedoch parallel zur Frontwand des Behälters ausgerichteter Drehachse angeordnet ist.This object is achieved according to the invention in that the vacuum interrupters are arranged with longitudinal axes oriented at right angles to the front wall of the container and that the switch-disconnector is arranged with an axis of rotation that is likewise horizontal, but aligned parallel to the front wall of the container.
Durch die Drehung sowohl des Vakuumschalters als auch des Lasttrennschalters um 90° bleiben die elektrischen Verbindungen zwischen diesen beiden Schaltgeräten unverändert erhalten. Andererseits können nun anstelle des bisher erforderlichen Umlenkgetriebes zwischen dem Vakuumschalter und der an der Frontwand sitzenden zugeordneten Antriebsvorrichtung zweckmäßig linear wirkende Antriebsteile eingesetzt werden. Beispiele hierfür sind der EP-A-0 354 803 oder der DE-A-41 23 710 zu entnehmen. In beiden Fällen ist jeder Vakuumschaltröhre eine Betätigungsstange zugeordnet, die mittels eines Faltenbalges abgedichtet in den Behälter eingeführt ist. Andererseits gelangen die Anschlußvorrichtungen des Lasttrennschalters in eine Stellung, die eine kreuzungsfreie Verbindung mit den an der Frontwand des Behälters vorgesehenen Abgangsdurchführungen ermöglicht.By rotating both the vacuum switch and the load break switch by 90 °, the electrical connections between these two switching devices remain unchanged. On the other hand, instead of the previously required deflection gear between the vacuum switch and the associated drive device seated on the front wall, it is now expedient to use linearly acting drive parts. Examples of this can be found in EP-A-0 354 803 or DE-A-41 23 710. In both cases, an actuating rod is assigned to each vacuum interrupter, which is inserted into the container in a sealed manner by means of a bellows. On the other hand, the connection devices of the switch disconnector come into a position which enables a cross-free connection to the outgoing feedthroughs provided on the front wall of the container.
Von der bisherigen Anordnung der Sammelschienen-Durchführungen in den Seitenwänden des Behälters kann ohne Nachteil abgesehen werden. Auch diese Durchführungen lassen sich an der Frontwand des Behälters anordnen und kreuzungsfrei mit dem Lasttrennschalter verbinden. Die Behälter einer mehrfeldrigen Schaltanlage können dann ohne seitlichen Abstand nebeneinander aufgestellt werden, wobei die Sammelschienen vor den Behältern in geeigneter Weise verlegbar und im Bedarfsfall anpaßbar sind.The previous arrangement of the busbar bushings in the side walls of the container can be dispensed with without disadvantage. These bushings can also be arranged on the front wall of the container and connected to the switch disconnector without crossing. The containers of a multi-panel switchgear can then be set up next to one another without lateral spacing, the busbars being able to be laid in a suitable manner in front of the containers and being adaptable if necessary.
Im Rahmen der Erfindung kann der Lasttrennschalter durch einen mit seiner Schalterwelle zusammenwirkenden inneren Schwenkhebel betätigbar sein, der an seinem der Frontwand des Behälters zugewandten Ende zum Eingriff eines äußeren, gegenüber der Frontwand gasdicht abgedichteten Schwenkhebels eine Gabelöffnung besitzt. Diese Anordnung ist vorteilhaft für die Montage des Lasttrennschalters, weil die Kupplung mit der Antriebsvorrichtung auf denkbar einfache Weise zustande kommt.In the context of the invention, the load-break switch can be actuated by an inner pivoting lever which interacts with its switch shaft and which, on its end facing the front wall of the container, engages an outer, has a fork opening against the front wall, sealed gas-tight. This arrangement is advantageous for the assembly of the switch disconnector, because the coupling with the drive device comes about in a very simple manner.
Die Erfindung wird im folgenden anhand der Figuren näher erläutert.The invention is explained in more detail below with reference to the figures.
Die Figur 1 zeigt seitlich aufgeschnitten ein Feld einer Mittelspannungs-Schaltanlage mit einem Vakuum-Leistungsschalter und einem Dreistellungs-Lasttrennschalter sowie den zugehörigen Antriebsvorrichtungen und den elektrischen Durchführungen.1 shows a section of a medium-voltage switchgear with a vacuum circuit breaker and a three-position switch-disconnector, as well as the associated drive devices and the electrical feedthroughs.
In der Figur 2 ist die nebeneinanderliegende Anordnung von drei Vakuumschaltröhren des Vakuum-Leistungsschalters nach der Figur 1 dargestellt. Nur die mittlere von drei oberen Isolierplatten ist gezeigt, um die darunterliegenden Teile sichtbar zu machen.FIG. 2 shows the side-by-side arrangement of three vacuum interrupters of the vacuum circuit breaker according to FIG. 1. Only the middle of three upper insulating plates is shown to make the parts underneath visible.
Das in den Figuren gezeigte Schaltfeld 1 weist einen zugangslos verschlossenen Behälter 2 aus Stahlblech auf, der einen als Ganzes mit 3 bezeichneten Vakuum-Leistungsschalter mit einer Antriebsvorrichtung 4 und einen Dreistellungs-Lasttrennschalter 5 mit einer zugehörigen weiteren Antriebsvorrichtung 6 umfaßt. Der Behälter 2 ist im Betrieb geerdet und enthält ein geeignetes Isoliergas, beispielsweise Schwefelhexafluorid (SF₆). An der Frontwand des Behälters 1 befinden sich Durchführungen 7 für Kabelabgänge 10 und weitere Durchführungen 11 als Einspeisung.The control panel 1 shown in the figures has a closed
Der Vakuum-Leistungsschalter 3 ist dreipolig ausgebildet und weist dementsprechend drei Vakuumschaltröhren 12 auf, die jeweils mittels einer geradlinig aufgebauten und eine Frontwand 13 des Behälter 1 durchsetzenden Kupplungsvorrichtung 14 durch die Antriebsvorrichtung 4 zum Ein- und Ausschalten betätigbar sind. Die drei Vakuumschaltröhren 12 liegen mit horizontaler Längsachse nebeneinander und sind in einer noch zu erläuternden Weise zwischen Isolierplatten befestigt. Der unterhalb des Vakuum-Leistungsschalters 3 angeordnete Lasttrennschalter 5 ist mit parallel zur Frontwand 13 des Behälters 2 verlaufender Drehachse angeordnet. Die drei Pole des Lasttrennschalters 5 liegen daher in der Figur 1 ebenso hintereinander wie die drei Vakuumschaltröhren 12. Daher können die Verbindungen zwischen beiden Schaltern ohne Kreuzung hierzu vorgesehener Stromschienen 15 leicht hergestellt werden. Ergebnis der beschriebenen Ausrichtung der Vakuumschaltröhren 12 und des Lasttrennschalter 5 zur Frontwand 13 des Behälters 2 ist es auch, daß einspeisende Stromschienen 16 kreuzungsfrei vertikal zwischen den Durchführungen 11 und den Vakuumschaltröhren 12 verlegbar sind. Die Durchführungen 11 sind in der Höhe gestuft angeordnet, um den Anschluß von Stromschienen zu erleichtern. Bei einer mehrfeldrigen Schaltanlage sind auf diese Weise die Sammelschienen frontseitig anzuschließen, ohne daß Zugang zum Innenraum der Behälter bestehen muß.The
Im folgenden werden Einzelheiten des Vakuum-Leistungsschalters 3 erläutert. Wie die Figur 1 zeigt, ist jeder Vakuumschaltröhre 12 eine obere Isolierplatte 17 zugeordnet, die an winkelförmigen Haltegliedern 20 befestigt sind. Die Halteglieder 20 sind an der Frontwand 13 und einer ihr gegenüberstehenden Rückwand 21 des Behälters 2 befestigt. Mit jeder oberen Isolierplatte 17 sind ein hinterer Träger 22 und ein vorderer Träger 23 verbunden, zwischen denen die Vakuumschaltröhre angeordnet ist. Jeweils eine obere Isolierplatte 17 mit den Trägern 22 und 23 sowie der Vakuumschaltröhre 12 bilden eine zwar nicht funktionsfähige, jedoch mechanisch zusammenhängende und montagefähige Einheit, die, solange der Behälter 2 noch offen ist, auf einfache Weise an den Haltegliedern 20 aufgehängt und befestigt werden kann.Details of the
Weiterer Bestandteil des Leistungsschalters 3 sind zwei untere Isolierplatten 24 und 25, die sich quer zu den oberen Isolierplatten 17 erstrecken und die ähnlich wie diese an Haltegliedern 26 befestigt sind, die ihrerseits an den Wänden des Behälters 2 befestigt sind. Die Isolierplatte 24 ist dabei gemeinsam für die hinteren, mit den Trägern 22 verbundenen Enden der Vakuumschaltröhren 12, während die Isolierplatte 25 gemeinsam für die vorderen, mit den Trägern 23 verbundenen Enden der Vakuumschaltröhren 12 ist. Diese Anordnung der Isolierplatten 17, 24 und 25 führt zu einer guten Versteifung gegen die hohen Kräfte, die Kurzschlußströme aufgrund der relativ kleinen gegenseitigen Abstände der Vakuumschaltröhren im Isoliergas hervorrufen können, während gleichzeitig die Zirkulation des in dem Behälter 2 befindlichen Isoliergases im Bereich der Vakuumschaltröhren 12 weniger als bei Verwendung einer einzigen unteren Isolierplatte behindert ist.Another component of the
Die unteren Halteglieder 26 sind zweckmäßig an gegenüberliegenden Seitenwänden 28 und 29 des Behälters 2 angebracht. Wird anstelle der einzelnen unteren Isolierplatten 24 und 25 eine gemeinsame untere Isolierplatte benutzt, so ist auch eine andere Anordnung der Halteglieder 26 möglich, beispielsweise sowohl an der Rückwand 21 als auch an den Seitenwänden 28 und 29. Auch empfiehlt es sich, eine für alle Vakuumschaltröhren 12 gemeinsame untere Isolierplatte so zu bemessen, daß sie ebenso wie die rechte untere Isolierplatte 25 in Richtung auf die Frontwand 13 nicht wesentlich über die Anschlußvorrichtung 30 hinausragt, damit die Elemente der Kupplungsvorrichtung 14 bei der Montage von unten gut zugänglich sind und das Isoliergas zirkulieren kann.The
An den hinteren Enden der Vakuumschaltröhren 12 sind Anschlußschienen 27 vorgesehen, die durch Öffnungen der unteren Isolierplatten 24 nach unten herausgeführt und dort mit den Stromschienen 16 verbunden sind. Die vorderen unteren Isolierplatten 25 tragen jeweils eine Anschlußvorrichtung 30 für die Stromschienen 15 und ein biegsames Stromband 31, das die elektrische Verbindung mit dem bewegbaren Anschlußbolzen 32 der Vakuumschaltröhre 12 herstellt.At the rear ends of the
Jede der Vakuumschaltröhren 12 ist, wie schon erwähnt, durch eine Kupplungsvorrichtung 14 mit der Antriebsvorrichtung 4 verbunden. Als Bestandteile der Kupplungsvorrichtung 14 sind eine Klemmvorrichtung 33, ein Isolierkörper 34 und eine Betätigungsstange 35 in Verbindung mit einem Faltenbalg 36 vorgesehen. Der Faltenbalg 36 ist mit seinem einen Ende in der Frontwand 13 des Behälters 2 befestigt und an seinem gegenüberliegenden, in den Behälter 2 hineinragenden Ende mit der Betätigungsstange 35 verbunden. Mit dem an der Außenseite des Behälter 2 zugänglichen Ende der Betätigungsstange 35 ist ein Hebelgetriebe 37 verbunden, zu dem eine als Kontaktkraftfeder und als Ausschaltfeder dienende Zugfeder 40 gehört. Das Hebelgetriebe kann vorzugsweise den in der DE-A-34 14 016 beschriebenen Aufbau besitzen. Die entsprechend der Polzahl vorhandenen Hebelgetriebe 37 werden zum Einschalten der Vakuumschaltröhren in bekannter Weise gemeinsam von der Antriebsvorrichtung 4 mit einer Antriebskraft beaufschlagt. Zum Ausschalten wird die Antriebsvorrichtung 4 entklinkt, worauf die Zugfeder 40 als Ausschaltfeder wirksam werden und die Vakuumschaltröhren 12 entgegen dem in dem Behälter bestehenden Gasdruck ausschalten kann.As already mentioned, each of the
Wie bereits erwähnt, gehört zu dem Schaltfeld 1 ein Dreistellungs-Lasttrennschalter 5, beispielsweise in der Bauart gemäß der DE-C-33 04 272. Die Schaltung des Leistungsschalters 3 und des Lasttrennschalters 5 kann insbesondere entsprechend der DE-A-39 15 949 gewählt sein, um Kurzschlußströme ohne eine gegenseitige Verriegelung des Leistungsschalters und des Lasttrennschalters beherrschen zu können.As already mentioned, the control panel 1 includes a three-position switch-disconnector 5, for example of the type according to DE-C-33 04 272. The circuit-
Eine für alle Pole des Lasttrennschalters 5 gemeinsame Schalterwelle 41 ist horizontal und parallel zur Frontwand 13 des Behälters 2 angeordnet. Die Antriebsvorrichtung 6 für den Lasttrennschalter 5 arbeitet mit der Schalterwelle 41 mittels einer weiteren, als Ganzes mit 42 bezeichneten Kupplungsvorrichtung zusammen, die so ausgebildet ist, daß der Einbau des Lasttrennschalters 5 in den Behälter 2 mit nur geringem Aufwand durchführbar ist. Hierzu weist die Kupplungsvorrichtung 42, wie an sich bekannt, einen Faltenbalg 43 auf, der mit seinem einen Ende gasdicht in der Frontwand 13 des Behälters 2 befestigt ist. Im Unterschied zu den Faltenbälgen 36 für die Vakuumschaltröhren 12 wird der Faltenbalg 43 nicht zur Einleitung einer linearen Bewegung, sondern einer Schwenkbewegung benutzt. Dies geschieht durch einen äußeren Schwenkhebel 44, dessen Schwenklager etwa in der Ebene der Frontwand 13 angeordnet ist. Am inneren Ende des äußeren Schwenkhebels 44 befindet sich ein Mitnehmerbolzen 45 für eine Gabelöffnung 46 eines inneren Schwenkhebels 47, der etwa mittig auf einem Lagerbolzen 50 gelagert ist. Am anderen Ende des inneren Schwenkhebels 47 wird durch ein Umlenkgetriebe 51 die Schalterwelle 41 betätigt. Zweckmäßig ist der innere Schwenkhebel 47 und das Umlenkgetriebe 51 an dem Lasttrennschalter 5 derart, befestigt, daß diese Einheit durch einfaches Aufschieben der Gabelöffnung 46 auf den Mitnehmerbolzen 45 mit dem äußeren Schwenkhebel 44 und damit mit der Antriebsvorrichtung 6 für den Lasttrennschalter 5 kuppelbar ist. Justier- und Einstellarbeiten können weitgehend entfallen.A common for all poles of the load break switch 5
