Description

Die Erfindung betrifft ein Hochspannungsschaltgerät mit einerseits einem Trennschalter oder einem Lasttrennschalter, insbesondere einem Drehtrennschalter, und andererseits mindestens einem Erdungsschalter, wobei zu dem Erdungsschalter ein Festkontakt und ein mittels eines Schwenkarmes in einer Schwenkebene schwenkbarer, mit dem Festkontakt in Kontakt bringbarer Schaltkontakt gehören, der Festkontakt z. B. an einer Freileitung, an einer Sammelschiene oder an der Strombahn bzw. an einer Strombahnhälfte des Trennschalters bzw. des Lasttrennschalters vorgesehen ist und der Schwenkarm mittels eines Schwenkarmhalters an eine Antriebswelle angeschlossen ist.The invention relates to a high-voltage switching device with on the one hand a disconnector or a load break switch, in particular a rotary disconnector, and on the other hand at least one earthing switch, the earthing switch comprising a fixed contact and a switching contact which can be pivoted in a swivel plane by means of a swivel arm and which can be brought into contact with the fixed contact, the fixed contact e.g. B. is provided on an overhead line, on a busbar or on the current path or on a current path half of the disconnector or the load break switch and the swivel arm is connected to a drive shaft by means of a swivel arm holder.

Bei Hochspannungsschaltgeräten der in Rede stehenden Art mit einem Trennschalter oder einem Lasttrennschalter, der zwei isolierende Stützer aufweist, z. B. bei Drehtrennschaltern und bei Hebeltrennschaltern, können nun an beiden Seiten des Trennschalters bzw. des Lasttrennschalters Erdungsschalter angebaut werden, die im Stand der Technik unterschiedlich ausgeführt sein müssen. Das ergibt sich bei Drehtrennschaltern z. B. aus der Tatsache, daß die Strombahnhälften nach einer Seite öffnen, so daß - wählt man als Beobachtungsort die Mitte des Drehtrennschalters - die eine Strombahnhälfte nach rechts, die andere Strombahnhälfte dagegen nach links öffnet. Entsprechend muß der jeweilige Erdungsschalter rechts bzw. links der Unterkonstruktion seine Schwenkebene haben. Außerdem müssen die Schwenkebenen der beiden Erdungsschalter zumindest um die größte Breite der Schwenkarme mit daran angebrachten Schaltkontakten gegeneinander versetzt sein, damit sich beim gleichzeitigen Betätigen der beiden Erdungsschalter ihre Schwenkarme mit den daran vorgesehenen Schaltkontakten nicht gegenseitig behindern.In high-voltage switching devices of the type in question with a circuit breaker or a load break switch that has two insulating supports, for. B. with rotary disconnectors and lever circuit breakers, earthing switches can now be installed on both sides of the disconnector or load break switch, which must be designed differently in the prior art. This is the case with rotary disconnectors z. B. from the fact that the current path halves open to one side, so that - one chooses the center of the rotary isolating switch as the observation point - one current path half opens to the right, the other current path half opens to the left. Accordingly, the respective earthing switch on the right or left of the substructure must have its swivel plane. In addition, the swivel planes of the two earthing switches must be offset from one another by at least the greatest width of the swivel arms with the switching contacts attached, so that when the two earthing switches are actuated simultaneously, their swivel arms with the switching contacts provided thereon do not interfere with one another.

Auch dann, wenn bei einem Hochspannungsschaltgerät der in Rede stehenden Art nur ein Erdungsschalter vorgesehen ist, gibt es im Stand der Technik Probleme. Je nach zur Verfügung stehendem Platz und Konstruktionsart der Hochspannungsschaltanlage kann es erforderlich sein, den Drehtrennschalter mit nach rechts öffnender Strombahn oder mit nach links öffnender Strombahn in die Hochspannungsschaltanlage einzubauen. Wenn ein Hochspannungsschaltgerät mit einem Drehtrennschalter mit einer nach rechts öffnenden Strombahn und zugehörigem Erdungsschalter geliefert worden ist, so kann der Drehtrennschalter nicht ohne weiteres als nach links öffnender Drehtrennschalter mit angebautem Erdungsschalter eingesetzt werden, nämlich nicht einfach dadurch, daß man ihn um 180 ° dreht, da sich dann der Erdungsschalter nicht mehr auf der Leitungsseite, sondern auf der Anlagenseite befindet. Baut man nun den Erdungsschalter um, also von der Anlagenseite auf die Leitungsseite, so befindet er sich nicht auf der linken Seite, sondern wie zuvor auf der rechten Seite, wo er jedoch beim Einschalten keinen Festkontakt vorfindet.Even if only one earthing switch is provided in a high-voltage switching device of the type in question, there are problems in the prior art. Depending on the space available and the type of construction of the high-voltage switchgear, it may be necessary to use the rotary disconnector To be installed in the high-voltage switchgear with the current path opening to the right or with the current path opening to the left. If a high-voltage switchgear has been supplied with a rotary isolating switch with a current path opening to the right and the associated earthing switch, the rotary isolating switch cannot readily be used as a left-opening rotary isolating switch with an attached earthing switch, namely not simply by rotating it through 180 °, since the earthing switch is then no longer on the line side but on the system side. If you now convert the earthing switch, i.e. from the system side to the line side, it is not on the left side, but as before on the right side, where there is no fixed contact when switched on.

Im Stand der Technik ist man den zuvor angedeuteten Problemen bisher dadurch begegnet, daß man unterschiedliche Bauteile verwendet hat. Das hat zu einer erhöhten Lagerhaltung, in seltenen Fällen auch zu einer fehlerhaften Montage geführt. Gelegentlich ist es auch zu Verzögerungen gekommen, nämlich dann, wenn gelieferte Hochspannungsschaltgeräte bei nicht korrekter Bestellung in der Hochspannungsschaltanlage den Anlagenbedingungen entsprechend umgebaut werden mußten.In the prior art, the previously indicated problems have been dealt with by using different components. This has led to increased warehousing and, in rare cases, incorrect assembly. Occasionally there are delays, namely when the high-voltage switchgear supplied had to be converted in accordance with the system conditions if the high-voltage switchgear was not ordered correctly.

Aus der DE - A - 2 628 020 ist ein Erdungsschalter bekannt, der mit einem als einseitiger Hebel ausgebildeten, beweglichen Kontakt und einem festen Gegenkontakt versehen ist. Zur sicheren Fuktionsweise im Kurzschlußfall weist der Gegenkontakt eine Stromschleife auf, deren elektrodynamisches Moment auf das freie Ende des beweglichen Kontaktes wirkt, und dem durch Kurzschlußstrom entstehenden Öffnungsmoment auf den beweglichen Kontakt entgegenwirkt, so daß dieser in der Einschaltstellung verbleibt. Etwaige Hinweise darauf, wie die eingangs erwähnte Problemstellung gelöst werden könnte, sind nicht gegeben.From DE-A-2 628 020 an earthing switch is known which is provided with a movable contact designed as a one-sided lever and a fixed counter contact. For safe operation in the event of a short circuit, the mating contact has a current loop, the electrodynamic moment of which acts on the free end of the movable contact and counteracts the opening moment caused by short-circuit current on the movable contact, so that it remains in the switched-on position. There are no indications of how the problem mentioned at the beginning could be solved.

Der Erfindung liegt nun die Aufgabe zugrunde, ein Hochspannungsschaltgerät der in Rede stehenden Art anzugeben, das frei ist von den zuvor aufgezeigten Problemen.The invention is based on the object of specifying a high-voltage switching device of the type in question which is free from the problems outlined above.

Das erfindungsgemäße Hochspannungsschaltgerät, bei dem die zuvor skizzierte Aufgabe gelöst ist, ist nun zunächst und im wesentlichen dadurch gekennzeichnet, daß der Schwenkarm wahlweise nicht nur auf der einen Seite oder der anderen Seite des Schwenkarmhalters, sondern auch nach rechts und links von den Seiten abstehend jeweils etwa quer zur Längsachse befestigbar ist, so daß die Antriebswelle und der Schwenkarmhalter ohne weiteres vier unterschiedliche Anbauarten des Schwenkarmes zulassen.The high-voltage switching device according to the invention, in which the previously outlined task is solved, is now initially and essentially characterized in that the swivel arm optionally not only on one side or the other side of the swivel arm holder, but also projecting to the right and left of the sides each can be fastened approximately transversely to the longitudinal axis, so that the drive shaft and the swivel arm holder readily permit four different types of attachment of the swivel arm.

In der Regel sind Hochspannungsschaltgeräte der hier in Rede stehenden Art für Drehstromsysteme ausgeführt, also dreipolig ausgeführt; zu einem dreipolig ausgeführten Hochspannungsschaltgerät gehören also drei Trennschalter, bzw. drei Lasttrennschalter und mindestens drei Erdungsschalter, vorzugsweise sechs Erdungsschalter, nämlich sechs Erdungsschalter dann, wenn die Trennschalter z. B. als Drehtrennschalter ausgeführt sind und bei geöffneter Strombahn sowohl eine Erdung der Leitungsseite als auch eine Erdung der Anlagenseite möglich sein soll. Bei einem solchen dreipoligen Hochspannungsschaltgerät wird man der Lehre der Erfindung gemäß die Schwenkarme, die Schwenkarmhalter, die Antriebswellen und alle eventuell erforderlichen Verbindungsgestänge und Kupplungen für alle Erdungsschalter gleich bzw. gleichartig ausführen.As a rule, high-voltage switching devices of the type in question are designed for three-phase systems, that is to say three-pole; to a three pole executed high-voltage switchgear include three disconnectors, or three switch disconnectors and at least three earthing switches, preferably six earthing switches, namely six earthing switches when the disconnector z. B. are designed as rotary isolating switches and both an earthing of the line side and an earthing of the system side should be possible when the current path is open. With such a three-pole high-voltage switching device, the teaching of the invention will be carried out according to the teaching of the swivel arms, the swivel arm holder, the drive shafts and any connecting rods and couplings that may be required for all earthing switches.

Zu jedem Erdungsschalter 2 gehört ein Festkontakt 10 und ein mittels eines Schwenkarmes 11 in einer Schwenkebene schwenkbarer, mit dem Festkontakt 10 in Kontakt bringbarer Schaltkontakt 12. Die Festkontakte 10 sind im dargestellten Ausführungsbeispiel jeweils an einer Strombahnhälfte 6 bzw. 7 der Drehtrennschalter 1 vorgesehen. Schließiich ist der Fig. 1 noch zu entnehmen, daß die Schwenkarme 11 der Erdungsschalter 2 jeweils mittels eines Schwenkarmhalters 13 an eine Antriebswelle 14 angeschlossen sind.1 shows a high-voltage switching device, specifically in a three-pole embodiment, that is to say for three-phase systems, with on the one hand three rotary disconnectors 1 and on the other hand six earthing switches 2. The three rotary disconnectors 1 are assigned a common rotary drive 3, while for three earthing switches 2 there is a common rotary drive 4 is provided. Each rotary isolating switch 1 includes two insulating supports 5 (cf. FIG. 2) and two current path halves 6, 7, the current path halves 6 having contact elements 8 and the current path halves 7 having mating contact elements 9 assigned to the contact elements 8 of the current path halves 6; this can be seen schematically in the right part of FIG. 1, in which the current path halves 6 and 7 are shown in broken lines in the open state.

Erfindungsgemäß lassen nun die Antriebswellen 14 und die Schwenkarmhalter 13 ohne weiteres vier unterschiedliche Anbauarten der Schwenkarme 11 zu. Im dargestellten Ausführungsbeispiel eines Hochspannungsschaltgerätes in dreipoliger Ausführung sind sowohl die Schwenkarme 11, die Schwenkarmhalter 13 und die Antriebswellen 14 als auch die Verbindungsgestänge 15 und die Kupplungen 16 für alle sechs Erdungsschalter 2 gleich bzw. gleichartig ausgeführt.According to the invention, the drive shafts 14 and the swivel arm holders 13 now permit four different types of attachment of the swivel arms 11. In the illustrated embodiment of a high-voltage switching device in a three-pole version, both the swivel arms 11, the swivel arm holder 13 and the drive shafts 14 as well as the connecting linkage 15 and the couplings 16 are designed identically or identically for all six earthing switches 2.

Die grundsätzliche Lehre der Erfindung, die Antriebswellen 14 und die Schwenkarmhalter 13 so auszuführen, daß sie ohne weiteres vier unterschiedliche Anbauarten der Schwenkarme 11 zulassen, wird vorzugsweise so realisiert, wie das in den Fig. 3, 4 und 5 dargestellt ist und im folgenden erläutert wird.The basic teaching of the invention, the drive shafts 14 and the swivel arm holder 13 so that they easily allow four different types of mounting of the swivel arms 11 is preferably implemented as shown in FIGS. 3, 4 and 5 and explained below becomes.

Den Fig. 3, 4 und 5 kann auch entnommen werden, daß die Schwenkarmhalter 13 in bezug auf ihre Längsachse symmetrisch aufgebaut und bearbeitet sind. Daraus resultiert, daß ein Schwenkarm 11 nicht nur auf der Vorderseite oder der Hinterseite des Schwenkarmhalters 13, sondern auch nach rechts oder nach links vorstehend befestigt werden kann. Dargestellt ist in den Fig. 3, 4 und 5 des weiteren, daß die Schwenkarmhalter 13 in bezug auf ihre Längsachse ein symmetrisches Bohrbild 17 aufweisen, d. h. daß die Bohrungen 18 zur Befestigung der Kupplungen 16 der Verbindungsgestänge 15 so realisiert sind, daß auch bei einer Drehung um 180° - Drehung der Verbindungsgestänge 15 oder der Schwenkantriebe 4 - eine Verbindung möglich ist.3, 4 and 5 show that the swivel arm holders 13 consist of flat material and the swivel arms 11 can be fastened either on one side or on the other side of the swivel arm holder 13. 3, 4 and 5 can also be seen that the swivel arm holder 13 are constructed and machined symmetrically with respect to their longitudinal axis. As a result, a swing arm 11 can be fixed not only on the front or the rear of the swing arm holder 13, but also to the right or to the left. 3, 4 and 5 also show that the swivel arm holders 13 have a symmetrical drilling pattern 17 with respect to their longitudinal axis, i. H. that the holes 18 for fastening the couplings 16 of the connecting rod 15 are realized so that a connection is possible even with a rotation of 180 ° - rotation of the connecting rod 15 or the swivel drives 4.

In Fig. 5 ist dargestellt, daß die Schwenkarmhalter 13 über einen Anschlußbolzen 19 mit einem Schubgestänge 20 des Schwenkantriebs 4 verbunden sind. Dabei ist der Anschlußbolzen 19 in einer zu dem symmetrischen Bohrbild 17 gehörenden Bohrung 21 befestigt. Denkbar ist jedoch auch eine nicht dargestellte Ausführungsform, bei der die Schwenkarmhalter seitlich vorstehende, in bezug auf ihre Längsachse symmetrisch angeordnete Anschlußaugen zum Anschluß des Schubgestänges des Schwenkantriebs aufweisen.5 shows that the swivel arm holders 13 are connected to a push rod 20 of the swivel drive 4 via a connecting bolt 19. The connecting bolt 19 is fastened in a bore 21 belonging to the symmetrical bore pattern 17. However, an embodiment which is not shown is also conceivable, in which the swivel arm holders have laterally projecting connection eyes arranged symmetrically with respect to their longitudinal axis for connecting the push rod of the swivel drive.

Schließlich kann den Fig. 3, 4 und 5 noch entnommen werden, daß im dargestellten Ausführungsbeispiel die Schwenkarme 11 mit Bügelschrauben 22 an den Schwenkarmhaltern 13 befestigt sind.Finally, FIGS. 3, 4 and 5 can also be seen that in the illustrated embodiment, the swivel arms 11 are fastened to the swivel arm holders 13 with bow screws 22.
