Abstract

In the case of an electrical switching installation having a plurality of switches for each phase, for example an earthing switch (1), a disconnector (2) and a circuit breaker (3), at least one of the switches, for example the earthing switch, has a motor drive (10) and a detachable mechanical coupling (5) which transmits the drive movement. The coupling (5) can be disengaged by operation of the disconnector (2) when it is being connected, so that, when the disconnector (2) is being connected, the earthing switch (1) cannot be moved into the earthing position, and this prevents high-voltage potential being connected to the earth potential. <IMAGE>

Description

Die Erfindung bezieht sich auf eine elektrische Schaltanlage mit mehreren Schaltern für jede Phase, insbesondere mit einem Leistungsschalter, wenigstens einen Trennschalter und wenigstens einem Erdungsschalter, wobei wenigstens ein Schalter einen Motorantrieb aufweist.The invention relates to an electrical switchgear assembly with a plurality of switches for each phase, in particular with a circuit breaker, at least one disconnector and at least one earthing switch, at least one switch having a motor drive.

Derartige Schaltanlagen können entweder als Freiluftschaltanlagen oder gekapselte Anlagen ausgeführt sein. Es können nicht alle Elemente einer solchen Schaltanlage zu jeder Zeit betätigt werden. Aus technischen Gründen und aus Sicherheitsgründen sind bestimmte Schaltungskombinationen ausgeschlossen. Beispielsweise darf eine Phase nicht mittels eines Erdungsschalters geerdet werden, wenn sie unter Betriebsspannung steht.Switchgear of this type can either be designed as an outdoor switchgear or encapsulated system. Not all elements of such a switchgear can be operated at all times. Certain circuit combinations are excluded for technical reasons and for safety reasons. For example, a phase must not be earthed using an earthing switch if it is under operating voltage.

Der Erfindung liegt die Aufgabe zugrunde, ein System von Sicherungen zu schaffen, das bei einer Schaltanlage der eingangs genannten Art gewährleistet, daß bestimmte unerwünschte bzw. unerlaubte Kombinationen von Schaltzuständen einzelner Schaltgeräte innerhalb der Schaltanlage sicher vermieden werden können.The invention has for its object to provide a system of fuses that ensures in a switchgear of the type mentioned that certain undesirable or unauthorized combinations of switching states of individual switching devices within the switchgear can be safely avoided.

Die Aufgabe wird erfindungsgemäß dadurch gelöst, daß zwischen dem Motorantrieb und dem Schalter eine lösbare mechanische Kupplung vorgesehen ist, die im Eingriff eine Antriebsbewegung übermittelt die durch Betätigung eines anderen Schalters in oder außer Eingriff bringbar ist.The object is achieved in that a releasable mechanical coupling is provided between the motor drive and the switch, which in engagement transmits a drive movement which can be brought into or out of engagement by actuating another switch.

Die Kupplung des mit einem Motorantrieb versehenen Schalters wird bei Betätigung eines anderen Schalters außer Eingriff gebracht, so daß der mit der Kupplung versehene Schalter nicht mehr betätigt werden kann. Beispielsweise wird beim Einschalten eines Trennschalters mittels eines mit dem Antrieb des Trennschalters verbundenen Mechanismus die Kupplung des Erdungsschalters außer Eingriff gebracht, so daß bei eingeschaltetem Trennschalter der Erdungsschalter nicht in Erdungsstellung gebracht werden kann.The clutch of the switch provided with a motor drive is disengaged when another switch is actuated, so that the switch provided with the clutch can no longer be actuated. For example, when a disconnector is switched on, the coupling of the earthing switch is disengaged by means of a mechanism connected to the drive of the disconnector, so that the earthing switch cannot be brought into the earthing position when the disconnector is switched on.

Es kann auch eine solche Kupplung mit mehreren anderen Schaltern gekoppelt sein, so daß sie durch Betätigung eines oder mehrerer dieser anderen Schalter außer Eingriff bringbar ist.Such a coupling can also be coupled to several other switches so that it can be disengaged by actuating one or more of these other switches.

Eine besondere Ausgestaltung der Erfindung sieht vor, daß die Kupplung mittels eines Schub/Zug-Seilzuges betätigbar ist.A special embodiment of the invention provides that the clutch can be actuated by means of a push / pull cable.

Die Schub/Zug-Seilzüge sind in der Technik bekannt und gestatten eine Umlenkung der Betätigungskräfte im Bereich der Schaltanlage. Dennoch gewährleisten sie eine sichere Betätigung der jeweils angeschlossenen Kupplung.The push / pull cables are known in the art and allow the actuation forces in the area of the switchgear to be deflected. Nevertheless, they ensure safe actuation of the connected coupling.

Eine vorteilhafte Ausgestaltung der Erfindung sieht vor, daß die Schaltanlage einen Leistungsschalter und einen Trennschalter aufweist und daß der Trennschalter einen Motorantrieb und eine lösbare Kupplung aufweist, die durch Einschalten des Leistungsschalters außer Eingriff bringbar ist.An advantageous embodiment of the invention provides that the switchgear has a circuit breaker and a circuit breaker and that the circuit breaker has a motor drive and a releasable coupling which can be disengaged by switching on the circuit breaker.

Hierdurch ist vermieden, daß bei eingeschaltetem Leistungsschalter der Trennschalter betätigt werden kann. Die Betätigung des Trennschalters bei eingeschaltetem Leistungsschalter ist technisch unerwünscht, da hierbei ein Lichtbogen gezogen würde, der innerhalb des Trennschalters nicht genügend schnell gelöscht werden kann, so daß der Trennschalter beschädigt werden würde.This avoids that the circuit breaker can be actuated when the circuit breaker is switched on. The operation of the circuit breaker with the circuit breaker switched on is technically undesirable since an arc would be drawn which cannot be extinguished quickly enough within the isolating switch, so that the isolating switch would be damaged.

Eine weitere vorteilhafte Ausgestaltung der Erfindung sieht vor, daß die elektrische Schaltanlage einen Trennschalter und einen Erdungsschalter enthält, und daß der Trennschalter einen Motorantrieb und eine lösbare Kupplung aufweist, die durch Einschalten des Erdungsschalters in Erdungsstellung oder durch Einschalten des Leistungsschalters außer Eingriff gebracht wird.Another advantageous embodiment of the invention provides that the electrical switchgear contains a disconnector and an earthing switch, and that the disconnector has a motor drive and a releasable coupling which is disengaged by turning on the earthing switch in the earthing position or by turning on the circuit breaker.

Hierdurch ist gewährleistet, daß der Trennschalter weder bei eingeschaltetem Leistungsschalter noch bei geerdetem Erdungsschalter betätigt werden kann. Es wird dadurch auch die Situation vermieden, daß bei eingeschaltetem Leistungsschalter und in Erdungsstellung befindlichem Erdungsschalter der Trennschalter eingeschaltet und damit die Betriebsspannung mit Erdpotential verbunden wird.This ensures that the disconnector cannot be actuated either when the circuit breaker is open or when the earthing switch is grounded. This also avoids the situation where the circuit breaker is switched on when the circuit breaker is switched on and the grounding switch is in the grounding position, and the operating voltage is thus connected to ground potential.

Eine weitere vorteilhafte Ausgestaltung der Erfindung sieht vor, daß die elektrische Schaltanlage einen Trennschalter und einen Erdungsschalter aufweist und daß der Erdungsschalter einen Motorantrieb und eine lösbare Kupplung aufweist, die durch Einschalten des Trennschalters außer Eingriff gebracht wird.A further advantageous embodiment of the invention provides that the electrical switchgear has a disconnector and an earthing switch and that the earthing switch has a motor drive and a releasable coupling which is disengaged by switching on the disconnector.

Hierdurch ist gewährleistet, daß bei eingeschaltetem Trennschalter der Erdungsschalter nicht in Erdungsstellung gebracht werden kann, da die Gefahr bestände, daß bei eingeschaltetem Trennschalter die Nennspannung mit dem Erdpotential durch Betätigung des Erdungsschalters verbunden werden könnte.This ensures that when the disconnector is switched on, the earthing switch cannot be brought into the grounding position, since there is a risk that the nominal voltage could be connected to the ground potential by actuating the earthing switch when the disconnector was switched on.

Im folgenden wird die Erfindung anhand eines Ausführungsbeispieles in einer Zeichnung gezeigt und anschließend beschrieben.In the following, the invention is shown on the basis of an exemplary embodiment in a drawing and then described.

Dabei zeigt die Figur einen Teil einer Schaltanlage in einer schematischen Darstellung.The figure shows part of a switchgear in a schematic representation.

In der Figur ist eine Leitungsführung zwischen einem ersten Anschlußpunkt 8, der beispielsweise durch eine Tranformatoreinspeisung gebildet sein kann und einen zweiten Anschlußpunkt 9, der beispielsweise durch eine Generatoreinspeisung gegeben sein kann, dargestellt. Die Leitungsführung weist einen ersten Erdungsschalter 1, einen Trennschalter 2, einen Leistungsschalter 3 und einen zweiten Erdungsschalter 4 auf. Der den ersten Anschlußpunkt 8 mit dem zweiten Anschlußpunkt 9 verbindende Leiter ist durch den Trennschalter 2 und durch den Leistungsschalter 3 unterbrechbar. Mittels des ersten Erdungsschalters 1 kann der dem Anschlußpunkt 8 zugewandte Teil des Leiters mit Erdpotential verbunden werden.The figure shows a line routing between a first connection point 8, which can be formed, for example, by a transformer feed, and a second connection point 9, which can be provided, for example, by a generator feed. The line routing has a first earthing switch 1, an isolating switch 2, a circuit breaker 3 and a second earthing switch 4. The conductor connecting the first connection point 8 to the second connection point 9 can be interrupted by the isolating switch 2 and by the circuit breaker 3. By means of the first earthing switch 1, the part of the conductor facing the connection point 8 can be connected to earth potential.

Mittels des zweiten Erdungsschalters 4 kann der dem zweiten Anschlußpunkt 9 zugewandte Teil des Leiters mit dem Erdpotential verbunden werden.The part of the conductor facing the second connection point 9 can be connected to the ground potential by means of the second grounding switch 4.

Der Erdungsschalter 1 ist über eine Kupplung 5 mit einem Motorantrieb 10 verbunden, der zur Betätigung des Erdungsschalters 1 in Gang gesetzt wird. Im Normalfall ist die Kupplung 5, die als mechanische Rastkupplung ausgeführt ist, in Eingriff, so daß mittels des Motorantriebes 10 der Erdungsschalter 1 betätigbar ist.The earthing switch 1 is connected via a coupling 5 to a motor drive 10 which is started to actuate the earthing switch 1. In the normal case, the coupling 5, which is designed as a mechanical latching coupling, is engaged so that the earthing switch 1 can be actuated by means of the motor drive 10.

Wird der Trennschalter 2 in die Einschaltstellung überführt, so wird mittels des Schub/Zug-Seilzuges 13 die Kupplung 5 des ersten Erdungsschalters 1 außer Eingriff gebracht, so daß der erste Erdungsschalter 1 danach nicht mehr betätigbar ist.If the isolating switch 2 is moved into the switch-on position, the clutch 5 of the first earthing switch 1 is disengaged by means of the push / pull cable 13, so that the first earthing switch 1 can then no longer be actuated.

Wird der Leistungsschalter 3 eingeschaltet, so wird mittels des mit dem Antrieb des Leistungsschalters 3 verbundenen Schub/Zug-Seilzuges 14 die Kupplung 6 des Trennschalters 2 außer Eingriff gebracht, so daß der Trennschalter 2 nicht mehr mittels seines Motorantriebes 11 betätigbar ist. Hierdurch wird vermieden, daß der Trennschalter 2 unter Hochspannung schaltet.If the circuit breaker 3 is turned on, the clutch 6 of the disconnector 2 is disengaged by means of the push / pull cable 14 connected to the drive of the circuit breaker 3, so that the disconnector 2 can no longer be actuated by means of its motor drive 11. This prevents the disconnector 2 from switching under high voltage.

Auch wenn der zweite Erdungsschalter 4 mittels seines Motorantriebes 12 in Einschaltstellung gebracht wird, wird über einen Schub/Zug-Seilzug 15 die Kupplung 6 des Trennschalters 2 entkoppelt. Auch hierdurch wird eine Verbindung eines unter Hochspannung stehenden Leiters mit dem Erdpotential verhindert.Even if the second earthing switch 4 is brought into the switched-on position by means of its motor drive 12, the clutch 6 of the isolating switch 2 is decoupled via a push / pull cable pull 15. This also prevents a high-voltage conductor from being connected to earth potential.

Der zweite Erdungsschalter 4 kann seinerseits nur dann betätigt werden, wenn der Trennschalter 2 sich in der Ausschaltstellung befindet, da bei einer Einschaltung des Trennschalters 2 über den Schub/Zug-Seilzug 16 die Kupplung 7 des zweiten Erdungsschalters 4 außer Eingriff gebracht wird.The second earthing switch 4 can in turn only be actuated when the isolating switch 2 is in the off position, since when the isolating switch 2 is switched on via the push / pull cable 16, the coupling 7 of the second earthing switch 4 is disengaged.

Durch das beschriebene System von gegenseitigen Sperrungen der verschiedenen Schalter untereinander werden Störfälle in der Schaltanlage sicher vermieden.The described system of mutually blocking the various switches from one another reliably prevents breakdowns in the switchgear.
