Description

Die Erfindung betrifft einen Hochspannungs-Leistungsschalter gemäß dem Oberbegriff des Patentanspruchs 1.The invention relates to a high-voltage circuit breaker according to the preamble of patent claim 1.

Derartige Leistungsschalter sind bereits bekannt. Bei diesen Schaltern sind die Polsäulen bezüglich des Grundgestells symmetrisch, d. h. auf der Längsmittellinie angeordnet. Der Schalterantrieb ist bei diesen Schaltern seitlich am Grundgestell angebracht, wobei die Schaltstrecken der einzelnen Polsäulen über Antriebsstangen betätigt werden. Es sind auch Schalter bekannt, bei denen jede Polsäule einen eigenen Antrieb aufweist. Diese Antriebe werden hydraulisch oder pneumatisch betätigt.Such circuit breakers are already known. In these switches, the pole columns are symmetrical with respect to the base frame, i. H. arranged on the longitudinal center line. In these switches, the switch drive is attached to the side of the base frame, the switching distances of the individual pole columns being actuated via drive rods. Switches are also known in which each pole column has its own drive. These drives are operated hydraulically or pneumatically.

Bei autopneumatischen Leistungsschaltern ist der Kraftbedarf groß, d. h. die die Polsäulen tragende Unterkonstruktion wird verhältnismäßig schwer. Die bekannten Anordnungen weisen wesentliche Nachteile auf, die vor allem darin bestehen, daß der Aufbau bzw. Zusammenbau aufwendig ist, da es sich um Schweißkonstruktionen handelt.With autopneumatic circuit breakers, the power requirement is large, i. H. the substructure carrying the pole columns becomes relatively heavy. The known arrangements have significant disadvantages, which consist primarily in the fact that the assembly or assembly is complex, since it is welded structures.

Der Erfindung liegt die Aufgabe zugrunde, die bekannten Schalter dahingehend zu verbessern, daß sie bezüglich Aufbau bzw. Zusammenbau weniger aufwendig sind.The invention has for its object to improve the known switches in that they are less expensive in terms of construction or assembly.

Diese Aufgabe wird erfindungsgemäß durch die den Patentanspruch 1 kennzeichnenden Merkmale gelöst. Mit dieser Lösung wird in vorteilhafter Weise ein Schalter geschaffen, der aus einigen Bausteinen auf sehr einfache Weise, z. B. auf der Baustelle, durch Verschrauben zusammensetzbar ist, wobei die Grundelemente, wie Stahlplatten, Antrieb, Ventile, Verbindungen, für verschiedene Schaltertypen einheitlich sein können. Die Schalter sind auch leicht demontierbar und weisen ein geringes Transportvolumen auf. Neben diesen Vorteilen ergibt sich, insbesondere auch wegen des asymmetrischen Aufbaus, eine Unterkonstruktion, die große Kräfte aufnehmen kann.This object is achieved by the features characterizing claim 1. With this solution, a switch is created in an advantageous manner, which consists of some components in a very simple manner, for. B. on site, can be assembled by screwing, the basic elements such as steel plates, drive, valves, connections, can be uniform for different types of switches. The switches are also easy to disassemble and have a low transport volume. In addition to these advantages, there is one, in particular also because of the asymmetrical structure Substructure that can absorb large forces.

Durch den asymmetrischen Aufbau werden auf einfache Weise ganz überraschende Vorteile erreicht. So wird eine leichte Zugänglichkeit zum Antrieb und insbesondere zu den Ventilen erreicht bei kleinstmöglichem Abstand zwischen den Längsträgern. Obwohl die Schienen entgegen jeder bisherigen Praxis bei Hochspannungs-Leistungsschaltern nur miteinander verschraubt sind, entsteht doch durch die drei die Polsäulen tragenden Platten, die mit den Längsträgern verschraubt sind, und andererseits durch die Platten der Stützsäulen ein gehäuseartiger und damit sehr fester Verband, der in der Lage ist, die beim Schalten auftretenden Beanspruchungen aufzunehmen, und bei dem dennoch eine leichte Zugänglichkeit zu den Antriebsteilen gegeben ist.Due to the asymmetrical structure, quite surprising advantages are easily achieved. In this way, easy access to the drive and in particular to the valves is achieved with the smallest possible distance between the side members. Although the rails, contrary to all previous practice in high-voltage circuit breakers, are only screwed together, the three plates supporting the pole columns, which are screwed to the side members, and the plates of the support columns, on the other hand, create a housing-like and therefore very firm bond, which in is able to absorb the stresses that occur during shifting, and yet has easy access to the drive parts.

Aus der DE-PS 712 536 ist zwar bereits ein elektrischer Hochleistungsschalter für hohe Spannungen bekannt, bei dem die Polsäulen asymmetrisch angeordnet sind. Bei diesem Schalter erfolgt die asymmetrische Anordnung der Polsäulen jedoch nur deshalb, weil pro Schaltpol zwei Polsäulen vorgesehen sind, die zur Wahrung der erforderlichen Schlagweite einerseits einen bestimmten Mindestabstand voneinander aufweisen müssen, wobei jedoch andererseits offenbar die gesamte Baulänge des Schalterrahmens möglichst klein gehalten werden soll. Bei dem bekannten Schalter mit nur einer Polsäule pro Schalterpol sind diese durchwegs symmetrisch auf dem Grundgestell angeordnet.From DE-PS 712 536 an electrical high-performance switch for high voltages is already known, in which the pole columns are arranged asymmetrically. In this switch, however, the asymmetrical arrangement of the pole columns is only because two pole columns are provided per switching pole, which on the one hand must have a certain minimum distance from each other in order to maintain the required pitch, but on the other hand, the overall length of the switch frame should obviously be kept as small as possible. In the known switch with only one pole column per switch pole, these are all arranged symmetrically on the base frame.

Die Schienen können mit unterschiedlichen Profilen abhängig von dem Abstand der Polsäulen aufgebaut werden.The rails can be constructed with different profiles depending on the distance between the pole columns.

Ein Ausführungsbeispiel der Erfindung ist in der Zeichnung dargestellt und im folgenden beschrieben.An embodiment of the invention is shown in the drawing and described below.

Es zeigen:

  • Figur 1 eine teilweise Seitenansicht des Schalters;
  • Figur 2 eine Unteransicht einer Unterkonstruktion mit Ständerplatten.
Show it:
  • Figure 1 is a partial side view of the switch;
  • Figure 2 is a bottom view of a substructure with stand plates.

Bei dem in Figur 1 dargestellten Schalter besteht der Grund- oder Unterrahmen aus zwei U-Profilen 2, die auf der Oberseite über drei Stahlplatten 4a, 4b, 4c miteinander verbunden sind. Auf der Unterseite sind zur Verbindung Profile 6 vorgesehen, die gleichfalls mit den U-Profilen 2 verschraubt sind.In the switch shown in Figure 1, the base or subframe consists of two U-profiles 2, the top on three Steel plates 4a, 4b, 4c are connected to each other. Profiles 6 are provided on the underside for connection, which are also screwed to the U-profiles 2.

Die Stahlplatten 4a, 4b, 4c weisen bezüglich der Längsmittellinie seitlich versetzte durchgehende Öffnungen 5a, 5b, 5c auf, in die die Polsäulen 8 eingesetzt sind, so daß sich ein asymmetrischer Aufbau ergibt.The steel plates 4a, 4b, 4c have through openings 5a, 5b, 5c which are laterally offset with respect to the longitudinal center line and into which the pole columns 8 are inserted, so that an asymmetrical structure results.

Der Schalterantrieb 10 ist unmittelbar mit der Polsäule 8 verbunden und die "Ein-" bzw. "Aus-"Ventile 12 bis 14 sind unmittelbar am Schalterantrieb angebracht.The switch drive 10 is connected directly to the pole column 8 and the "on" and "off" valves 12 to 14 are attached directly to the switch drive.

Mit dem "Aus-"Ventil 14 ist über ein Steckrohr 18, das mittels 0-Ringen (nicht dargestellt) abgedichtet ist, ein Behälter 19 für Druckluft für den Schalterantrieb verbunden.A container 19 for compressed air for the switch drive is connected to the “off” valve 14 via a plug-in tube 18, which is sealed by means of 0-rings (not shown).

Bei der in Figur 2 dargestellten Ausgestaltung sind an der Unterseite des Grundrahmens Stahlplatten 24 angeschraubt, die Teil eines nicht näher dargestellten Schalter-Ständers 25 bilden. Mit dieser Ausgestaltung wird eine Reduzierung der verwendeten Bauteile bei gleichzeitiger hoher Belastbarkeit erreicht.In the embodiment shown in Figure 2 steel plates 24 are screwed to the underside of the base frame, which form part of a switch stand 25, not shown. With this configuration, the components used are reduced while at the same time being highly resilient.
