Schaltvorrichtungen der vorgenannten Art werden in der Fachsprache mit Trennschalter bezeichnet, wenn sie zum Unterteilen von Streckenabschnitten, zur Verbindung paralleler Gleise oder zur Unterteilung von Einspeisungen eingesetzt werden. Sie werden als Erdungshalter bezeichnet, wenn sie einen bereits abgeschalteten Streckenabschnitt erden sollen. Trennschalter gibt es auch in Kombination mit einem Erdkontakt, d.h. nach Trennung des Streckenabschnittes wird dieser zusätzlich an Erde gelegt.Switching devices of the aforementioned type are in the technical language designated with disconnect switch when to divide of sections of track, for connecting parallel tracks or used to subdivide infeeds. They are referred to as grounding holders if they already have one disconnected section of the route should be earthed. disconnectors is also available in combination with an earth contact, i.e. after separation of the route section, this becomes additional laid to earth.

Die Montage solcher Schaltvorrichtungen erfolgt in der Regel auf Traversen an Oberleitungsmasten. Bekannte Schaltvorrichtungen dieser Art, wie sie beispielsweise im Siemens-Katalog FM 1995, Sektion 13/6 beschrieben sind, umfassen zwei Isolatoren, von denen der eine starr und der andere auf einer Achse zum Ein- und Ausschalten schwenkbar an einem Sockel angeordnet ist. Die Stabisolatoren sind aus Keramik gefertigt und fest am Sockel einzementiert. Am Kopfteil der Isolatoren befindet sich ein Schaltkontaktsatz mit einem Kontaktmesser am schwenkbeweglichen Isolatorteil und einer mit dem Kontaktmesser zusammenwirkenden Kontaktfeder am starren Isolatorteil. Such switching devices are usually installed on trusses on overhead line masts. Known switching devices of this type, for example in the Siemens catalog FM 1995, section 13/6, comprise two isolators, one of them rigid and the other on one Axis for switching on and off arranged on a base is. The rod insulators are made of ceramic and cemented firmly to the base. On the head part of the isolators there is a switch contact set with a contact knife on the pivotable isolator part and one with the contact knife interacting contact spring on the rigid insulator part.

Obgleich sich die bekannten Schaltvorrichtungen bewährt haben, gilt es, sie hinsichtlich des Aufbaus und der Montage, insbesondere der Montage beim Austausch der an sich sehr bruchanfälligen Isolatoren und auch hinsichtlich des Austauschs der Kontaktsätze, noch weiter zu verbessern.Although the known switching devices have proven themselves, it is important to them in terms of construction and assembly, especially the assembly when replacing the very breakable insulators and also in terms of replacement of contact sets to improve even further.

Der im Anspruch 1 angegebenen Erfindung liegt demnach die Aufgabe zugrunde, eine Schaltvorrichtung der eingangs genannten Art anzugeben, die insbesondere einfacher aufgebaut ist, weniger störanfällig ist und die insbesondere bei Wartungsarbeiten leichter zu montieren ist.The invention specified in claim 1 is therefore the Task based on a switching device of the aforementioned Specify a type that is particularly simple, is less susceptible to faults, especially during maintenance work is easier to assemble.

Die erfindungsgemäß vorgestellte Schaltvorrichtung braucht bezüglich der Gestaltung des Kontaktsatzes lediglich auf zwei unterschiedliche Bauteile zurückzugreifen, einerseits auf vorzugsweise L-förmig gestaltete Kontaktmesser und andererseits auf an den Kontaktmessern beidseitig anliegende Kontaktfedern. Mit diesen beiden Bauteilen, die vorzugsweise bei allen Varianten der Schaltvorrichtung gleich ausgebildet sind, lassen sich sowohl Trennschalter als auch Erdungsschalter als auch eine Kombination beider Schalter zusammenstellen. Mit wenigen Bauteilen lassen sich so Schalter unterschiedlicher Funktionen kostengünstig erstellen.The switching device presented according to the invention needs with regard to the design of the contact set, only two to use different components, on the one hand preferably L-shaped contact blades and on the other hand on contact springs on both sides of the contact blades. With these two components, preferably at all variants of the switching device are the same disconnect switches as well as earthing switches as well as a combination of both switches. With just a few components, switches can be different Create functions inexpensively.

Die Kontaktfedern sind vorteilhafterweise an den Kontaktmessern justierbar gehaltert. Damit lassen sich die Kontaktfedern genau auf die Kontaktmesser einstellen; Fertigungstoleranzen können so weitgehend ausgeglichen und die Übergangswiderstände auf ein Minimum reduziert werden. Vorteilhafterweise sind die Kontaktfedern mit Einstellmitteln versehen, mit denen sich die Federkraft der Kontaktfedern einstellen lassen.The contact springs are advantageously on the contact blades adjustable. This allows the contact springs adjust exactly to the contact blades; manufacturing tolerances can largely compensate and the contact resistance be reduced to a minimum. advantageously, the contact springs are provided with adjusting means, with which the spring force of the contact springs is adjusted to let.

Eine besonders einfache Konstruktion, insbesondere im Hinblick auf einen Austausch eines Kontaktsatzes oder eines Stabisolators läßt sich erzielen, wenn gemäß einer weiteren vorteilhaften Ausgestaltung der Erfindung der Schaltkontaktsatz direkt an den Stabisolatoren befestigt ist, indem die einen Schenkel der L-förmig gebogenen Kontaktmesser direkt an Anschlußteilen der Stabisolatoren lösbar befestigt sind.A particularly simple construction, especially with regard to exchange of a contact set or rod insulator can be achieved if according to another advantageous Embodiment of the invention of the switch contact set is attached directly to the rod insulators by one Leg of the L-shaped contact blades directly on the connecting parts the rod insulators are releasably attached.

Die schwenkbeweglich gehalterten Stabisolatoren können mit Vorteil am einen Schenkel des Kontaktmessers ein Betätigungselement aufweisen, welches bei einem Erdungsschalter einen am feststehenden Stabisolator befindlichen Signalschalter (Positionsschalter) betätigt. Damit kann bei geschlossenem Kontaktsatz ein Signal für die vorhandene Erdung gegeben werden.The pivotable rod insulators can also be used Advantage on one leg of the contact knife an actuator have, which at an earthing switch a fixed rod isolator located signal switch (Position switch) actuated. So when closed Contact set a signal for the existing grounding can be given.

Um den Austausch der Stabisolatoren zu vereinfachen, sind diese am Sockel abnehmbar montiert; hierzu sind die Stabisolatoren zumindest am sockelseitigen Ende hülsenförmig ausgebildet und auf entsprechend ausgebildeten, im Sockel befestigbaren Halterungen aufgesetzt. Die Halterungen sind zweckmäßigerweise sowohl in bezug auf den Sockel als auch in bezug auf die Stabisolatoren mit Hilfe geeigneter Einstellschrauben justierbar gehaltert.To simplify the exchange of the rod insulators, are these are detachably mounted on the base; for this are the rod insulators at least at the base end of the sleeve and on appropriately trained, attachable in the base Mounts attached. The brackets are convenient both in terms of the base and in terms of on the rod insulators with the help of suitable adjusting screws adjustable.

    • Die Figur 1 zeigt eine als Trennschalter ausgebildete Schaltvorrichtung. Auf einem Sockel 1 sind zwei Stabisolatoren 2, 3 gehaltert, die an ihren oberen Enden einen Schaltkontaktsatz 4 tragen. Während der Stabisolator 2 am Sockel 1 fest montiert ist, ist der Stabisolator 3 mittels Gelenk 5 schwenkbeweglich gehaltert. An einem Hebelarm 6 des schwenkbeweglichen Teils des Stabisolators 3 greift ein in der Darstellung nicht eingezeichneter Antrieb an, der die Schwenkbewegung (siehe Pfeile) im Fall einer Abschaltung des Streckenabschnittes veranlaßt. Mit 7 sind Löschhörner bezeichnet, die in bekannter Weise beim Einschalten und Abschalten die Linienkontakte der später noch näher erläuterten Schaltkontakte schützen.FIG. 1 shows a switching device designed as a disconnector. On a base 1 there are two rod insulators 2, 3 supported a switch contact set at their upper ends 4 wear. While the rod insulator 2 is firmly attached to the base 1 the rod insulator 3 can be pivoted by means of a joint 5 supported. On a lever arm 6 of the pivotable Part of the rod insulator 3 does not engage in the illustration shown drive, which the pivoting movement (see Arrows) in the event of a shutdown of the route section causes. With 7 fire extinguishing horns are referred to in known way when switching on and off the line contacts the switch contacts explained in more detail later protect.

    Bevor Details über Aufbau des Schaltkontaktsatzes 4 sowie Halterung der Isolatoren am Sockel bzw. am Schaltkontaktsatz näher beschrieben werden, werden verschiedene Modifikationen der Schaltvorrichtung vorgestellt.Before details about the construction of the switching contact set 4 as well Holding the isolators on the base or on the switch contact set Various modifications are described presented the switching device.

    Die Figur 2 zeigt die Anordnung nach Figur 1 mit einem zusätzlichen Erdkontakt. Hierzu ist am Sockel 1 eine mit der Erdleitung verbundene Halterung 8 vorgesehen, die mehrere Kontaktfedern 9 aufnimmt, welche mit einem Kontaktmesser 10 korrespondieren. Das Kontaktmesser 10 ist an Teilen des Schaltkontaktsatzes 4 befestigt, welche am schwenkbeweglichen Stabisolator angeordnet sind. In der ausgeschwenkten Stellung, in der die später noch näher erläuterten Schaltkontakte des Schaltkontaktsatzes 4 voneinander getrennt sind, greift das Kontaktmesser 10 zwischen die Kontaktfedern 9 ein. In dieser Stellung ist eine sichere Erdung der Leitung bzw. des Streckenabschnittes gewährleistet. FIG. 2 shows the arrangement according to FIG. 1 with an additional one Ground contact. For this purpose, one with the Earth line connected bracket 8 provided the several Contact springs 9 receives, which with a contact knife 10th correspond. The contact knife 10 is on parts of the Switch contact set 4 attached, which on the pivotable Rod insulator are arranged. In the swung out position in which the switch contacts explained in more detail later of the switch contact set 4 are separated from one another the contact knife 10 between the contact springs 9. In this position is a safe grounding of the line or the Section guaranteed.

    Die Figur 3 zeigt eine Version, die unter Verwendung gleicher Bauteile ähnlich aufgebaut ist, jedoch hier als reiner Erdungsschalter ausgeführt ist. Der Erdungsschalter ist hier im geöffneten Zustand (Normalfall) gezeichnet; in dieser Position sind die Schaltkontaktpaare 4.1 und 4.2 des Schaltkontaktsatzes 4 voneinander getrennt. Über den beiden Schaltkontaktpaaren 4.1 und 4.2 sind Schutzhauben 13, 14 angeordnet, die die Schaltkontakte gegen mechanische Beschädigungen und Witterungseinflüsse schützen. Gleiches gilt auch für die zuvor beschriebenen Ausführungsformen.Figure 3 shows a version using the same Components are constructed similarly, but here as a pure earthing switch is executed. The earthing switch is here in the opened state (normal case) drawn; in this position are the switch contact pairs 4.1 and 4.2 of the switch contact set 4 separated from each other. Above the two switch contact pairs 4.1 and 4.2 protective hoods 13, 14 are arranged, which the switch contacts against mechanical damage and protect the weather. The same applies to the Embodiments described above.

    Anhand der Figur 4 wird ein Schaltkontaktsatz 4 näher erläutert. Der Schaltkontaktsatz 4 umfasst die beiden Schaltkontaktpaare 4.1 und 4.2 von denen der eine dem feststehenden und der andere dem schwenkbeweglich gehalterten Stabisolator zugeordnet ist. Jedes Schaltkontaktpaar ist gleich aufgebaut und besteht im wesentlichen aus zwei Teilen, einem L-förmig gebogen Kontaktmesser 15 und einer daran montierten Kontaktfeder 16. Wie aus der Darstellung ersichtlich, sind die Kontaktmesser und die korrespondierend dazu angeordneten Kontaktfedern paarweise und rotationssymmetrisch gedreht angeordnet. Die Kontaktfedern 16 sind am einen, längeren Schenkel 15a justierbar befestigt, so daß sie sich auf die mit ihnen korrespondierenden Kontaktmesser am anderen Kontaktpaar ausrichten lassen. Zweckmäßigerweise ist die mit 17 angedeutete Schraubverbindung hierzu in einem entsprechend ausgebildeten Langloch geführt. Mit Hilfe dieser Justierung können Fertigungstoleranzen, die beispielsweise beim Biegen der Kontaktmesser 15 auftreten, ausgeglichen werden. Beim Schalten auftretende Übergangswiderstände lassen sich so auf ein Minimum reduzieren. Die Federkraft kann durch federbelastete Einstellmittel 18 ebenfalls eingestellt und damit an die Gegebenheiten angepaßt werden.A switching contact set 4 is explained in more detail with reference to FIG. 4. The switch contact set 4 comprises the two switch contact pairs 4.1 and 4.2 of which the one the fixed and the other the pivotable rod insulator assigned. Each switch contact pair is constructed identically and consists essentially of two parts, an L-shaped bent contact knife 15 and a contact spring mounted thereon 16. As can be seen from the illustration, the contact blades and the correspondingly arranged contact springs arranged in pairs and rotated symmetrically. The contact springs 16 are on one, longer leg 15a adjustably fastened so that they are on with them Align the corresponding contact knife with the other contact pair to let. The one indicated at 17 is expedient Screw connection for this in a suitably designed Elongated hole. With the help of this adjustment, manufacturing tolerances, for example when bending the contact knife 15 occur, be balanced. Occurring when switching Contact resistance can be reduced to a minimum to reduce. The spring force can be adjusted by spring-loaded 18 also set and thus to the circumstances be adjusted.

    Die Befestigung der Schaltkontaktpaare 4.1 und 4.2 an den Stabisolatoren 2 und 3 bzw. 11 und 3 erfolgt in der Weise, daß der längere Schenkel 15a an der mit 19 bezeichneten Stelle an einem Anschlußteil 20 (Figur 1) angeschraubt wird. Die Schraubverbindung ist in Figur 1 mit der Position 21 bezeichnet. Diese leicht lösbare Schraubverbindung ermöglicht in Verbindung der später noch näher erläuterten Befestigung der Stabisolatoren am Sockel 1 ein leichtes problemloses Austauschen der Stabisolatoren.The attachment of the switch contact pairs 4.1 and 4.2 to the Rod insulators 2 and 3 or 11 and 3 are made in such a way that the longer leg 15a on the designated 19 Place on a connector 20 (Figure 1) is screwed. The screw connection is designated by the position 21 in FIG. This easily detachable screw connection enables in connection with the fastening explained in more detail later the rod insulators on base 1 are easy to replace the rod insulators.

    Am kürzeren Schenkel 15b befinden sich weitere Bohrungen 22, an denen, wie in Figur 3 am Beispiel des Erdungsschalters dargestellt, mittels eines nicht näher bezeichneten Winkels ein Betätigungselement 23 befestigt werden kan. Das Betätigungselement 23 wirkt zusammen mit einem am Stabisolator 11 befestigten, in der Darstellung durch die Schutzhaube 14 verdeckten und deshalb nicht erkennbaren Positionsschalter 24, welcher im hochgeschwenkten Zustand des Stabisolators 3 betätigt und ein Signal geben kann, daß eine Erdung stattgefunden hat.On the shorter leg 15b there are further bores 22, to which, as shown in FIG. 3 using the example of the earthing switch, an actuating element 23 can be fastened by means of an angle (not shown in more detail) Representation covered by the protective hood 14 and therefore not recognizable position switch 24, which actuates the rod insulator 3 in the pivoted-up state and can give a signal that grounding has taken place.

    Die am längeren Schenkel 15a vorhandenen Bohrungen 25 dienen zur Befestigung der Anschlußkabel für die Stromzuführung bzw. Ableitung.The holes 25 on the longer leg 15a serve for fastening the connection cables for the power supply or Dissipation.

    Die Figur 5 zeigt teilweise im Schnitt die Halterung des Stabisolators 2 am Sockel 1. Der Stabisolator 2 besteht im wesentlichen aus einem mit Silikon ummantelten GFK-Stab, der entlang seiner Länge eine Vielzahl von aufgespritzten Silikonkappen 26 aufweist. Das dem Sockel 1 zugewandte Endteil 27 des Stabisolators ist hülsenförmig ausgebildet und auf einer Hülse 28 aufgesetzt. Die Hülse 28 ist wiederum in einem Sockelteil 29 des Sockels 1 gehaltert. Die Halterung einerseits der Hülse 28 und andererseits des Endteils 27 des Stabisolators 2 ist so ausgeführt, daß eine genaue Justierung des Stabisolators am Sockel 1 durchgeführt werden kann. Hierzu sind am Umfang der Teile mehrere Stellschrauben 30 angeordnet. Alternativ dazu kann das Ende des Stabisolators auch stabförmig ausgebildet und in einer entsprechend vorgesehenen Hülse des Sockels justierbar gehaltert sein.FIG. 5 shows the holder of the Rod insulator 2 on the base 1. The rod insulator 2 consists of essentially made of a silicone-coated GRP rod that a variety of molded silicone caps along its length 26 has. The end part 27 facing the base 1 the rod insulator is sleeve-shaped and on a Sleeve 28 placed. The sleeve 28 is in turn in a base part 29 of the base 1 held. The bracket on the one hand the sleeve 28 and on the other hand the end part 27 of the rod insulator 2 is designed so that an accurate adjustment of the Rod insulator can be carried out on the base 1. For this a plurality of set screws 30 are arranged on the circumference of the parts. Alternatively, the end of the rod insulator can also be used rod-shaped and provided accordingly Sleeve of the base can be adjustable.
