Description

Die Erfindung betrifft einen Trennschalter mit einem Gehäuse, in welchem wenigstens ein Stellglied, eine Krafterzeugungs- und -übertragungseinheit zur Bewegung des Stellgliedes und eine Steuereinheit angeordnet sind.The invention relates to a disconnector with a housing in which at least one actuator, a power generation and transmission unit for Movement of the actuator and a control unit are arranged.

Trennschalter der gattungsgemäßen Art werden insbesondere im Fahrleitungsbereich spurgeführter Verkehrsmittel eingesetzt und dienen dort vor allem der Betätigung von Spannungsabschaltern. Solche Abschalter sind in erster Linie Sicherheitsschalter und die Schaltung erfolgt signalgesteuert über grössere Entfernungen. Die Trennschalter müssen also sehr zuverlässig, schnell und auch nach längerer Standzeit und nach längerem Stillstand arbeiten, um über das Stellglied Spannungsabschalter betätigen zu können.Disconnectors of the generic type are used in particular in Catenary area of track-guided means of transport used and serve there all the actuation of voltage cut-offs. Such shutdowns are first Line safety switches and the switching is signal-controlled via larger ones Distances. The disconnectors must therefore be very reliable, fast and also after a long standstill and after a long standstill work to Actuator voltage switch to be able to operate.

Gattungsgemäße Trennschalter sind der Witterung ausgesetzt und weisen ein zumindest spritzwasserdichtes Gehäuse auf, welches von dem Stellglied, meist eine Schaltstange mit Gabelkopf, durchragt wird. Im Gehäuse sind bei herkömmlichen Trennschaltern ein Elektromotor und ein Zahnradgetriebe angordnet, welches mit der Schaltstange im Eingriff ist. Über mehradrige Zuleitungen werden einerseits der Betriebsstrom, andererseits Steuersignale zugeführt, die von einer Steuerung umgesetzt werden, um den Elektromotor für das Verfahren der Schaltstange anzusteuern. Disconnectors of the generic type are exposed to the weather and show at least splash-proof housing, which from the actuator, usually a shift rod with fork head is protruded. In the case are at conventional disconnectors an electric motor and a gear transmission arranged, which is engaged with the shift rod. About multi-core The operating current on the one hand, and control signals on the other hand fed, which are implemented by a controller to the electric motor for to control the movement of the shift rod.

Die herkömmlichen Trennschalter bringen eine Reihe von Nachteilen mit sich. Durch die Verwendung von Zahnradgetrieben sind die Herstellung, vor allem aber die Montage und Einstellung der Teile relativ zueinander aufwendig. Bei Störungen ist daher häufig der gesamte Trennschalter auszutauschen. Schaltpositionen und Schaltweg sind nicht sehr exakt einstellbar. Vor allem bei Kälte aber auch mit zunehmender Standzeit wird das Getriebe äußerst schwergängig. Es kommt zum sogenannten

Figure 00020001
springen" des Getriebes. Da auch die Spannungsabschalter der Witterung ausgesetzt sind, werden sehr große Schaltkräfte benötigt. Dies erfordert starke Elektromotoren, welche eine hohe Stromaufnahme haben. Dadurch wird die Stellentfernung stark beschränkt und liegt meist bei maximal zwei Kilometern, da darüber hinaus die erforderliche elektrische Energie nicht mehr mit herkömmlichen Leitungen angeliefert werden kann. Anderenfalls würde jedoch die Installation verteuert. Die Getiebeanordnung bewirkt eine große Geräuschentwicklung, was häufig unerwünscht ist, beispielsweise beim Einsatz im städtischen Straßenbahnbereich. Für den Störungsfall weisen herkömmliche Trennschalter Kurbelgetriebe auf. Für einen Stellweg von beispielsweise 200 mm werden jedoch 60 bis 80 Umdrehungen benötigt, so daß die Abschaltung zeitaufwendig wird.The conventional disconnectors have a number of disadvantages. Through the use of gear drives, the manufacture, but above all the assembly and adjustment of the parts relative to one another is complex. In the event of malfunctions, the entire disconnector must therefore be replaced. Switching positions and switching travel cannot be set very precisely. The transmission becomes extremely stiff, especially when it is cold, but also with increasing service life. It comes to the so-called

jump "of the transmission. Since the voltage switches are also exposed to the weather, very large switching forces are required. This requires strong electric motors that have a high current consumption. This means that the distance between the positions is greatly limited and is usually a maximum of two kilometers, since the required electrical energy can no longer be supplied with conventional cables, but otherwise the installation would become more expensive. The drive arrangement causes a large amount of noise, which is often undesirable, for example when used in urban trams. Conventional disconnectors have crank mechanisms in the event of a malfunction for example 200 mm, however, 60 to 80 revolutions are required, so that the shutdown is time-consuming.

Ausgehend von diesem Stand der Technik liegt der vorliegenden Erfindung die Aufgabe zugrunde, einen Trennschalter der gattungsgemäßen Art dahingehend zu verbessern, daß dieser wirtschaftlich herstellbar, einfach zu montieren und zu warten und unter Vermeidung der oben genannten Nachteile auch nach längerer Stillstandszeit äußerst betriebssicher ist.Based on this prior art, the present invention Task based on a disconnector of the generic type improve that this is economically producible, easy to assemble and to wait and avoid the disadvantages mentioned above even after a long time Downtime is extremely reliable.

Zur technischen Lösung dieser Aufgabe wird vorgeschlagen, daß die Krafterzeugungs- und -übertragungseinheit elektrohydraulisch ausgelegt ist.To solve this problem technically, it is proposed that the Power generation and transmission unit is designed electrohydraulically.

Die Herstellung, vor allem aber die Montage und Einstellung der Teile relativ zueinander werden erheblich vereinfacht. Modultechnik ermöglicht den Austausch von Einzelelementen. Schaltpositionen und Schaltweg sind sehr exakt einstellbar. The production, but above all the assembly and adjustment of the parts relatively to each other are considerably simplified. Modular technology enables the exchange of individual elements. Switch positions and switching travel can be set very precisely.

Auch bei Kälte aber auch nach längerem Stillstand bleibt das Getriebe leichtgängig. Die Anordnung bewirkt eine sehr geringe Geräuschentwicklung. Neben der Erzeugung hoher Stellkräfte werden somit auch exakte Stellpositionen erzielt.The transmission remains even when it is cold but also after a long standstill smooth. The arrangement causes very little noise. In addition to the generation of high positioning forces, exact positioning positions are also possible achieved.

Der erfindungsgemäße Trennschalter umfaßt einen elektrischen Antriebsmotor, ein Hydraulikaggregat mit Hydraulikpumpe und einen mit dem Stellglied verbindbaren Hydraulikzylinder. Er ist somit modular aufgebaut, so daß sowohl die Montage als auch die Wartung sehr vereinfacht sind. Der Elektromotor kann sehr viel schwächer ausgelegt werden, als dies im Stand der Technik erforderlich ist, obwohl der erfindungsgemäße Trennschalter höhere Schaltkräfte erzeugt. Dadurch wird nicht zuletzt die Stellentfernung erheblich vergrößert, bis zu acht Kilometer bei Verwendung von Stromleitungen mit 2,5 mm2 . Die Erfindung macht es jedoch auch möglich, daß der Elektroantrieb mit Solarstrom auskommt. Dadurch kann eine völlig neue Stelltechnik im einschlägigen Anwendungsbereich eingeführt werden, indem die Trennschalter ortsflexibler werden. Auch können zusätzlich die Steuersignale auf alternativen Wegen zugeleitet werden, z.B. über Lichtwellenleiter, Funk, Digitalnetze und dergleichen.The disconnector according to the invention comprises an electric drive motor, a hydraulic unit with a hydraulic pump and a hydraulic cylinder which can be connected to the actuator. It is therefore modular, so that both assembly and maintenance are very simplified.

Last but not least, this considerably increases the distance to the site, up to eight kilometers when using power lines with 2.5 mm 2 . However, the invention also makes it possible for the electric drive to make do with solar power. This enables a completely new positioning technology to be introduced in the relevant area of application by making the isolating switches more flexible in terms of location. The control signals can also be supplied in alternative ways, for example via optical fibers, radio, digital networks and the like.

Die Genauigkeit wird verbessert und die erzeugbaren Kräfte erhöht.The hydraulic pump is preferably a reversing control and Hydraulic cylinder a differential actuator. The accuracy is improved and the generated forces increased.

In Vorteilhafter Weise weist der erfindungsgemäße Trennschalter eine hydraulische Handpumpe auf. Mit nur drei bis vier Hüben kann der gesamte Stellweg gefahren werden. Weiterhin ist vorgesehen, daß der Trennschalter eine hydraulische Sperreinrichtung umfaßt, um ein Verstellen auszuschließen. Auch wird vorgeschlagen, daß der erfindungsgemäße Trennschalter verstellbare elektrische Endlagenschalter umfaßt. Diese sind auf die jeweilige Schaltsituation einstellbar und der Trennschalter flexibel einsetzbar. The disconnector according to the invention advantageously has one hydraulic hand pump on. With just three to four strokes, the entire Travel. It is also provided that the disconnector hydraulic locking device includes to exclude an adjustment. Also it is proposed that the disconnector according to the invention be adjustable includes electrical limit switches. These are based on the respective switching situation adjustable and the disconnector can be used flexibly.

Der Trennschalter weist eine Steuereinheit auf, welche in Abhängigkeit von eingehenden Steuersignalen den Elektromotor für die Hydraulikpumpe ansteuert. Vorzugsweise ist die Steuereinheit für einen drahtlosen Signalempfang ausgelegt.The isolating switch has a control unit which, depending on incoming control signals controls the electric motor for the hydraulic pump. The control unit is preferably designed for wireless signal reception.

Der erfindungsgemäße ist in einem wasserdicht verschließbaren Gehäuse angeordnet. Vorzugsweise ist an einem Gehäusedeckel eine Sicherheitsschalter angeordnet.

This is not with one closable door shown, namely waterproof via the lid seal 10.

Durch die Hydraulikpumpeneinheit 8, im Ausführungsbeispiel eine elektrohydraulische Reversiersteuerung, wird ein Differentialstellzylinder 3 betätigt, der mechanisch über einen Mitnehmer 12 mit der Stellstange 1 gekoppelt ist, die die Stellkraft direkt über den Gabelkopf 9 auf ein nicht gezeigtes Schalterelement überträgt. Die Stellstange 1 ist mittels Stangenführungen 11 und 15 geführt, wobei die obere auch eine wasserdichte Abdichtung umfaßt.By the hydraulic pump unit 8, one in the exemplary embodiment electrohydraulic reversing control, a differential actuating cylinder 3 is actuated, which is mechanically coupled via a driver 12 to the actuating rod 1, the the actuating force directly via the fork head 9 on a switch element, not shown transmits.
