Description
Die Erfindung betrifft ein Stromunterbrechersystem nach dem Oberbegriff des Patentanspruchs 1.The invention relates to a circuit breaker system according to the preamble of patent claim 1.
Bei der Verwendung von Vakuumschaltröhren für eine Hochspannungsanwendung, wie z. B. aus der
Die Aufgabe der Erfindung besteht darin, ein Stromunterbrechersystem bereitzustellen, das mindestens zwei Unterbrechereinheiten unterschiedlicher Bauart aufweist, die von einem gemeinsamen Antriebssystem angetrieben werden.The object of the invention is to provide a current interrupter system which has at least two interrupter units of different designs which are driven by a common drive system.
Die Lösung der Aufgabe besteht in einem Stromunterbrechersystem mit den Merkmalen des Patentanspruchs 1.The solution to the problem consists in a circuit breaker system with the features of patent claim 1.
Das Stromunterbrechersystem gemäß Patentanspruch 1 weist eine serielle Anordnung von mindestens zwei Unterbrechereinheiten auf. Hiervon ist mindestens eine Unterbrechereinheit eine Vakuumröhre, wobei die mindestens zwei Unterbrechereinheiten mit einem Antriebssystem mechanisch verbunden sind. Das Antriebssystem weist ein Antriebsaggregat auf und es zeichnet sich dadurch aus, dass eine Kurbelwelle als Antriebswelle vorhanden ist, die mindestens zwei Kurbeln aufweist, wobei die mindestens zwei Kurbeln zwei unterschiedlich hohe Kurbelhübe aufweisen.The current interrupter system according to patent claim 1 has a serial arrangement of at least two interrupter units. At least one interrupter unit is a vacuum tube, wherein the at least two breaker units are mechanically connected to a drive system. The drive system has a drive assembly and is characterized in that a crankshaft is present as the drive shaft, which has at least two cranks, the at least two cranks having two different crank strokes.
Durch die unterschiedlich hohen Hübe der Kurbelwelle ist es möglich, über eine einzige Antriebswelle zwei Unterbrechereinheiten unterschiedlicher Bauart und somit auch unterschiedlicher Hübe mit einer Antriebseinheit und einem Antriebssystem zu betreiben. Dies bietet wirtschaftliche Vorteile, da für die zwei Unterbrechereinheiten lediglich ein Antriebssystem, insbesondere ein Antriebsaggregat erforderlich ist.Due to the different strokes of the crankshaft, it is possible to operate two interrupter units of different designs and thus also different strokes with one drive unit and one drive system via a single drive shaft. This offers economic advantages, since only one drive system, in particular one drive unit, is required for the two interrupter units.
Unter dem Begriff Kurbel wird eine an der Kurbelwelle angebrachte Exzentrizität verstanden, die bezüglich der Drehachse der Kurbelwelle im Wesentlichen senkrecht verläuft. Die Kurbel kann dabei im einfachsten Fall nahezu stabförmig ausgestaltet sein. Sie ist in der Praxis zur Vermeidung von Unwuchten in der Regel in Form von asymmetrischen Exzenterscheiben ausgestaltet. Unter dem Begriff Kurbel wird auch ein Kurbelpaar verstanden, das entlang der Kurbelwelle beabstandet zueinander angeordnet ist und bezüglich der Drehachse exzentrisch über einen bezüglich der Drehachse im Wesentlichen parallel verlaufenden Kurbelzapfen miteinander verbunden ist.The term crank is understood to mean an eccentricity attached to the crankshaft, which runs essentially perpendicularly with respect to the axis of rotation of the crankshaft. In the simplest case, the crank can be designed to be almost rod-shaped. In practice, to avoid imbalances, it is generally designed in the form of asymmetrical eccentric discs. The term crank is also understood to mean a pair of cranks which is arranged at a distance from one another along the crankshaft and is connected to one another eccentrically with respect to the axis of rotation via a crank pin which runs essentially parallel with respect to the axis of rotation.
Unter dem Begriff Kurbelhub ist die Exzentrizität des Kurbelzapfens bezüglich der Drehachse der Kurbelwelle verstanden, wobei der Kurbelzapfen bei einer Drehbewegung der Kurbelwelle eine kreisförmige Bewegung um die Drehachse der Kurbelwelle beschreibt. Der Kurbelhub entspricht somit auch dem Radius dieser beschriebenen Kreisbewegung des Kurbelzapfens. Unter dem Begriff serielle Anordnung von Unterbrechereinheiten wird verstanden, dass die Unterbrechereinheiten elektrisch in Reihe geschaltet sind.The term crank stroke is understood to mean the eccentricity of the crank pin with respect to the axis of rotation of the crankshaft, with the crank pin describing a circular movement about the axis of rotation of the crankshaft during a rotary movement of the crankshaft. The crank stroke thus also corresponds to the radius of this described circular movement of the crank pin. The term serial arrangement of interrupter units means that the interrupter units are electrically connected in series.
In einer vorteilhaften Ausgestaltungsform der Erfindung vollzieht die Kurbelwelle während eines Öffnungsvorgangs der Unterbrechereinheiten eine unidirektionale Bewegung. Dies hat den Vorteil, dass der Antrieb wiederum technisch einfacher gegenüber dem Stand der Technik ausgestaltet sein kann, da er lediglich in eine Richtung drehbar sein muss. Die Möglichkeit der unidirektionalen Drehbewegung bei einem Öffnungsvorgang, insbesondere bei einem Öffnungsvorgang einer Rotation von 170 bis 170°, bevorzugt 180° beträgt, wird durch die Anwendung der erfindungsgemäßen Kurbelwelle ermöglicht.In an advantageous embodiment of the invention, the crankshaft performs a unidirectional movement during an opening process of the interrupter units. This has the advantage that the drive can in turn be configured in a technically simpler manner than in the prior art, since it only has to be rotatable in one direction. The possibility of a unidirectional rotational movement during an opening process, in particular during an opening process of a rotation of 170 to 170°, preferably 180°, is made possible by using the crankshaft according to the invention.
Einen weiteren Vorteil spielt die Anwendung der Kurbelwelle als Antriebswelle des Antriebssystems dann aus, wenn ein Öffnungsvorgang der Unterbrechereinheiten und ein anschließender Schließvorgang eine unidirektionale Bewegung vollzieht, die zwischen 350° und 360° + 10° liegt. Hierbei vollzieht die Kurbelwelle einen Öffnungs- und einen Schließvorgang bei einer vollständigen Umdrehung, die bevorzugt 360° beträgt, durch das Einstellen bestimmter Kontaktüberhübe kann es auch zweckmäßig sein, dass die Kurbelwelle eine Drehbewegung vollzieht, die von den 360° geringfügig, also um +/- 10° abweicht.The use of the crankshaft as the drive shaft of the drive system has a further advantage when an opening process of the interrupter units and a subsequent closing process complete a unidirectional movement of between 350° and 360° + 10°. In this case, the crankshaft completes an opening and a closing process during a complete rotation, which is preferably 360°. By setting certain contact overtravels, it can also be expedient for the crankshaft to complete a rotary movement that is slightly different from the 360°, i.e. by +/- - 10° deviates.
Dabei stehen in einer bevorzugten Ausgestaltungsform der Erfindung jeweils zwei unterschiedliche Unterbrechereinheiten mit den jeweils unterschiedlichen Kurbeln der Kurbelwelle, die einen unterschiedlichen Kurbelhub aufweisen, mechanisch in Verbindung, wobei die beiden Unterbrechereinheiten sich darin unterscheiden, dass sie unterschiedliche Bemessungsspannungen aufweisen. Die Bemessungsspannung einer Unterbrechereinheit ist dabei die Spannung, bis zu der die Unterbrechereinheit technisch zugelassen Stromflüsse unterbrechen kann. Auf diese Weise können Unterbrechereinheiten mit unterschiedlichen Bemessungsspannungen miteinander in Serie geschaltet werden, wodurch sich eine nächsthöhere Klasse von Bemessungsspannung ergibt. Hierfür ist es zweckmäßig, unterschiedliche Unterbrechereinheiten zu verwenden.In a preferred embodiment of the invention, two different interrupter units are mechanically connected to the respective different cranks of the crankshaft, which have a different crank stroke, with the two interrupter units differing in that they have different rated voltages. The rated voltage of an interrupter unit is the voltage up to which the interrupter unit can technically interrupt current flows. In this way, interrupter units with different rated voltages can be connected in series with one another be, which results in a next higher class of rated voltage. For this it is expedient to use different interrupter units.
Unter dem Begriff mechanisch in Verbindung stehen wird verstanden, dass zur Übertragung einer Kraft, eines Impulses oder einer Aktion zwischen zwei Systemen eine mechanische Verbindung besteht, die beispielsweise über bewegliche Verbindungen wie Lager oder Gelenke, aber auch über feste Verbindungen wie stoffschlüssige oder Kraftschlüssige Verbindungen oder aus Kombinationen aus beweglichen und festen Verbindungen erfolgen kann.The term “mechanically connected” means that there is a mechanical connection for the transmission of a force, an impulse or an action between two systems, for example via movable connections such as bearings or joints, but also via fixed connections such as material or non-positive connections or from combinations of movable and fixed connections.
In einer weiteren Ausgestaltungsform der Erfindung ist es ferner zweckmäßig, drei gleichartige Paare von seriell geschalteten Unterbrechereinheiten mechanisch miteinander zu verbinden. Die drei Paare der Unterbrechereinheiten bilden die drei Phasen des Stromnetzes ab, sodass die drei Phasen durch diese Ausgestaltungsform jeweils mit zwei in Serie geschalteten Unterbrechereinheiten bis zu einer vorgegebenen Bemessungsspannung mit einem einzigen Antriebssystem betrieben werden können.In a further embodiment of the invention, it is also expedient to mechanically connect three pairs of the same type of interrupter units connected in series. The three pairs of interrupter units form the three phases of the power grid, so that the three phases can each be operated with two series-connected interrupter units up to a predetermined rated voltage with a single drive system using this embodiment.
In einer konstruktiven Ausgestaltungsform des Stromunterbrechersystems weist die mechanische Verbindung zwischen der Kurbelwelle und jeweils einer Unterbrechereinheit einen Kurbelzapfen auf, der zwischen zwei Kurbeln so angeordnet ist, dass er beabstandet zu einer Drehachse der Kurbelwelle verläuft, wobei der Kurbelzapfen von einem Gleitlager umgeben ist, das wiederum an einer Schubstange angeordnet ist. Durch eine derartige konstruktive Ausgestaltungsform ist es möglich, die Rotationsbewegung der Kurbelwelle in eine translatorische Bewegung eines Bewegkontaktes des Unterbrechersystems umzuwandeln. Dabei steht die Schubstange im Weiteren mit dem Kontaktbolzen mechanisch in Verbindung, dies kann wiederum insbesondere durch ein weiteres Gleitlager an der Schubstange erfolgen, das wiederum an einem Zapfen am Kontaktbolzen angebracht ist. Eine beschriebene Schubstange, die an beiden Enden ein Gleitlager aufweist, kann auch als Pleuelstange bezeichnet werden.In one design embodiment of the circuit breaker system, the mechanical connection between the crankshaft and one interrupter unit each has a crank pin, which is arranged between two cranks in such a way that it runs at a distance from an axis of rotation of the crankshaft, the crank pin being surrounded by a plain bearing, which in turn is arranged on a push rod. Such a constructive embodiment makes it possible to convert the rotational movement of the crankshaft into a translatory movement of a moving contact of the interrupter system. In this case, the push rod is also mechanically connected to the contact bolt; this can in turn be effected in particular by a further slide bearing on the push rod, which in turn is attached to a pin on the contact bolt. A described push rod, the has a slide bearing at both ends can also be referred to as a connecting rod.
In einer weiteren Ausgestaltungsform der Erfindung ist die Kurbelwelle in der Art ausgestaltet, dass eine radiale Ausrichtung des Kurbelhubs zweier benachbarter Kurbeln entlang der Kurbelwelle um 180° versetzt angeordnet sind. Dies führt dazu, dass die einzelnen Unterbrechereinheiten, die mit den jeweiligen Kurbelzapfen der Kurbelwelle in mechanischer Verbindung stehen, bezüglich einer Linie entlang der Kurbelwelle versetzt zueinander angeordnet sind, was in einer Einsparung eines Bauraumes resultiert. Eine derartige Anordnung von Unterbrechereinheiten bedarf somit weniger Bauraum, was insbesondere dann zum Tragen kommt, wenn die Unterbrechereinheiten in geschlossenen Räumen angeordnet sind.In a further embodiment of the invention, the crankshaft is designed in such a way that a radial alignment of the crank stroke of two adjacent cranks along the crankshaft is offset by 180°. The result of this is that the individual interrupter units, which are mechanically connected to the respective crank pins of the crankshaft, are arranged offset relative to one another with respect to a line along the crankshaft, which results in a saving in installation space. Such an arrangement of interrupter units therefore requires less installation space, which is particularly important when the interrupter units are arranged in closed rooms.

Die Unterbrechereinheiten 4, 6 weisen dabei ein Kontaktsystem 36 auf, das zwei Kontakte, einen Bewegkontakt 38 und einen Festkontakt 40 umfassen. Das Kontaktsystem 36 ist umgeben von einem Gehäuse 42 in einem Vakuumraum 44 angeordnet. Die Darstellung gemäß
Die serielle Schaltung der beiden Unterbrechereinheiten 4, 6 wird durch eine Kontaktierung über Stromschienen 48, die mit einem flexiblen Stromband 46 elektrisch in Verbindung stehen, das wiederum den Kontaktbolzen 50 kontaktiert, erzeugt. Eine weitere Verbindung über Stromschienen 48 und Strombänder 46 erfolgt weiter über den Festkontakt 40 und einen ihm zugeordneten Bolzen und dem Bewegkontakt 32` der Unterbrechereinheit 6. Hierbei kann es sich um zwei Vakuumschaltröhren handeln, die beispielsweise eine Bemessungsspannung von 170 kV (Unterbrechereinheit 4) und eine Bemessungsspannung von 145 kV (Unterbrechereinheit 6) aufweisen. Durch diese serielle Anordnung von Vakuumschaltröhren mit verschiedenen Bemessungsspannungen addiert sich die Bemessungsspannung des gesamten Stromunterbrechersystems aus den Bemessungsspannungen der einzelnen Unterbrechereinheiten.The serial connection of the two

Es kann hierbei auf eine technisch aufwendige, bidirektionale Antriebsbewegung verzichtet werden, wobei dies nicht zwingend notwendig ist.
