Schaltvorrichtung zum Zu- und Abschalten oder Erden von Streckenabschnitten bei FahrleitungsanlagenSwitching device for connecting and disconnecting or earthing sections of the track in overhead contact line systems
Die Erfindung betrifft eine Schaltvorrichtung zum Zu- und Abschalten oder Erden von Streckenabschnitten bei Fahrleitungsanlagen, enthaltend mindestens einen an einem Sockel fest montierten ersten Stabisolator und einem korrespondierend dazu am Sockel schwenkbar gehalterten zweiten Stabisolator und einem am freien Ende der Stabisolatoren angeordneten, aus Kontaktmessern und Kontaktfedern gebildeten Schaltkontaktsatz .The invention relates to a switching device for connecting and disconnecting or earthing sections of the line in overhead contact line systems, comprising at least one first rod insulator fixedly mounted on a base and a second rod insulator which is pivotably held on the base, and a contact insulator and contact springs arranged at the free end of the rod insulators formed switch contact set.
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 be- reits 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 referred to in technical jargon as isolating switches if they are used for dividing sections of track, for connecting parallel tracks or for dividing infeeds. They are referred to as earthing brackets if they are to be used to earth a section of the route that has already been switched off. Disconnectors are also available in combination with an earth contact, i.e. After separating the section of the route, it is also connected 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 Kontakt- messer zusammenwirkenden Kontaktfeder am starren Isolatorteil. 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 Aus- tauschs der Kontaktsätze, noch weiter zu verbessern.Such switching devices are usually mounted on crossbars on overhead line masts. Known switching devices of this type, as described for example in the Siemens catalog FM 1995, section 13/6, comprise two isolators, one of which is rigid and the other is pivotably arranged on an axis for switching on and off on a base. The rod insulators are made of ceramic and firmly cemented to the base. On the top part of the isolators there is a switch contact set with a contact knife on the pivotable isolator part and a contact spring on the rigid isolator part which interacts with the contact knife. Although the known switching devices have proven themselves, it is important to improve them still further with regard to their construction and assembly, in particular assembly when replacing the insulators, which are very fragile per se, and also with regard to the exchange of the contact sets.
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 based on the object of specifying a switching device of the type mentioned, which in particular is of simpler construction, is less prone to failure and which is easier to assemble, in particular for maintenance work.
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.With regard to the design of the contact set, the switching device presented according to the invention only needs to fall back on two 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, which are preferably of the same design in all variants of the switching device, both isolating switches and earthing switches and a combination of both switches can be put together. With just a few components, switches with different functions can be produced 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. Vorteilhafter- weise sind die Kontaktfedern mit Einstellmitteln versehen, mit denen sich die Federkraft der Kontaktfedern einstellen lassen.The contact springs are advantageously held in an adjustable manner on the contact blades. This allows the contact springs to be adjusted precisely to the contact blades; Manufacturing tolerances can be largely compensated for and the contact resistance reduced to a minimum. The contact springs are advantageously provided with adjusting means with which the spring force of the contact springs can be adjusted.
Eine besonders einfache Konstruktion, insbesondere im Hin- blick 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, in particular with a view to replacing a contact set or a rod insulator, can be achieved if, according to a further advantageous embodiment of the invention, the switch contact set is directly attached to the rod insulators by the one leg of the L-shaped contact blades are detachably attached directly to connecting parts of the rod insulators.
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 pivoted rod insulators can advantageously have an actuating element on one leg of the contact blade, which actuates a signal switch (position switch) located on the fixed rod insulator in the case of an earthing switch. This means that a signal for the existing grounding can be given when the contact set is closed.
Um den Austausch der Stabisolatoren zu vereinfachen, sind diese am Sockel abnehmbar montiert; hierzu sind die Stabiso- latoren 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.In order to simplify the exchange of the rod insulators, they are detachably mounted on the base; for this purpose, the rod insulators are sleeve-shaped at least at the base-side end and are placed on appropriately designed holders which can be fastened in the base. The brackets are expediently held adjustable with the aid of suitable adjusting screws both with respect to the base and with respect to the rod insulators.
Weitere vorteilhafte Ausgestaltungen und Weiterbildungen ergeben sich aus der nachfolgenden Beschreibung mehrerer Ausführungsbeispiele. Es zeigen:Further advantageous refinements and developments result from the following description of several exemplary embodiments. Show it:

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. Wahrend 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 Loschhorner bezeichnet, die in bekannter Weise beim Einschalten und Abschalten die Linienkontakte der spater noch naher erläuterten Schaltkontakte schützen.FIG. 1 shows a switching device designed as a disconnector. On a base 1, two rod insulators 2, 3 are held, which carry a switch contact set 4 at their upper ends. While the rod insulator 2 is fixedly mounted on the base 1, the rod insulator 3 is pivotally supported by means of a joint 5. On a lever arm 6 of the pivotable part of the rod insulator 3, a drive (not shown in the drawing) engages, which causes the pivoting movement (see arrows) in the event of a shutdown of the section of the route. With 7 Loschhorner are designated, which protect the line contacts of the switch contacts explained later in more detail when switching on and off.
Bevor Details über Aufbau des Schaltkontaktsatzes 4 sowie Halterung der Isolatoren am Sockel bzw. am Schaltkontaktsatz naher beschrieben werden, werden verschiedene Modifikationen der Schaltvorrichtung vorgestellt.Before details about the structure of the switch contact set 4 and the mounting of the isolators on the base or on the switch contact set are described in more detail, various modifications of the switching device are presented.
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 desFIG. 2 shows the arrangement according to FIG. 1 with an additional earth contact. For this purpose, a holder 8, which is connected to the earth line, is provided on the base 1 and accommodates a plurality of contact springs 9, which correspond to a contact knife 10. The contact knife 10 is on parts of the
Schaltkontaktsatzes 4 befestigt, welche am schwenkbeweglichen Stabisolator angeordnet sind. In der ausgeschwenkten Stellung, n der die spater noch naher erläuterten Schaltkontakte des Schaltkontaktsatzes 4 voneinander getrennt s nd, greift das Kontaktmesser 10 zwischen die Kontaktfedern 9 ein. In dieser Stellung st eine sichere Erdung der Leitung bzw. des Streckenabschnittes gewährleistet . 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.Switch contact set 4 attached, which are arranged on the pivotable rod insulator. In the pivoted-out position, which separates the switching contacts of the switching contact set 4, which are explained in more detail later, the contact knife 10 engages between the contact springs 9. In this position, a safe grounding of the line or of the route section is guaranteed. FIG. 3 shows a version which is constructed in a similar manner using the same components, but is here designed as a pure earthing switch. The earthing switch is drawn here in the open state (normal case); in this position the switch contact pairs 4.1 and 4.2 of the switch contact set 4 are separated from each other. Protective hoods 13, 14 are arranged above the two switch contact pairs 4.1 and 4.2, which protect the switch contacts against mechanical damage and weather influences. The same applies to the previously described embodiments.
Anhand der Figur 4 wird ein Schaltkontaktsatz 4 näher erläutert. Der Schaltkontaktsatz 4 umfasst die beiden Schaltkon- taktpaare 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 Kontakt- feder 16. Wie aus der Darstellung ersichtlich, sind die Kon- taktmesser 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 Kontakt- messer 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, one of which is assigned to the fixed rod insulator and the other to the rod insulator which is held pivotably. Each switch contact pair is constructed identically and essentially consists of two parts, an L-shaped bent contact knife 15 and a contact spring 16 mounted thereon. As can be seen from the illustration, the contact knives and the correspondingly arranged contact springs are rotated in pairs and rotationally symmetrically arranged. The contact springs 16 are adjustably attached to one, longer leg 15a so that they can be aligned with the contact blades corresponding to them on the other pair of contacts. For this purpose, the screw connection indicated by 17 is expediently guided in an appropriately designed elongated hole. This adjustment can be used to compensate for manufacturing tolerances which occur, for example, when the contact blades 15 are bent. In this way, contact resistances occurring during switching can be reduced to a minimum. The spring force can also be adjusted by spring-loaded adjusting means 18 and thus adapted to the circumstances.
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 switching contact pairs 4.1 and 4.2 are attached to the rod insulators 2 and 3 or 11 and 3 in such a way that that the longer leg 15a is screwed to the point designated 19 on a connecting part 20 (Figure 1). The screw connection is designated by the position 21 in FIG. This easily releasable screw connection, in conjunction with the fastening of the rod insulators to the base 1, which will be explained in more detail later, enables the rod insulators to be replaced easily and without problems.
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 specified 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 present on the longer leg 15a serve to fasten the connecting cables for the power supply or discharge.
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, partly in section, the mounting of the rod insulator 2 on the base 1. The rod insulator 2 essentially consists of a GRP rod covered with silicone, which has a large number of sprayed-on silicone caps 26 along its length. The end part 27 of the rod insulator facing the base 1 is sleeve-shaped and placed on a sleeve 28. The sleeve 28 is in turn held in a base part 29 of the base 1. The holder on the one hand of the sleeve 28 and on the other hand of the end part 27 of the rod insulator 2 is designed so that a precise adjustment of the rod insulator on the base 1 can be carried out. For this purpose, several 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 adjustable in a correspondingly provided sleeve of the base.
