Abstract

A high-voltage compressed-gas circuit breaker has contact plates with a contact face for the incoming cables. The position of these contact faces and the attachment bores on the contact faces for the connection of cables will vary depending on the form of installation given in the switching equipment. The circuit breaker has contact faces which are formed as contact parts which are separate from the terminal plates. On both contact parts, bores are provided for connecting the contact part and the terminal plate to each other, these bores protruding beyond the outside diameter of the interrupter unit on which the terminal plate is applied. The bores make possible a reversal of the contact face by 180 DEG .

Description

Die Erfindung bezieht sich auf einen elektrischen Hochspannungs-Leistungsschalter, insbesondere Druckgas-Leistungsschalter, dessen Unterbrechereinheiten an den äußeren Stirnseiten jeweils mit Anschlußplatten abgeschlossen sind, die eine Anschlußfläche für Leitungen aufweisen, die dort befestigt werden.The invention relates to an electrical high-voltage circuit breaker, in particular a compressed gas circuit breaker, the interrupter units of which are terminated on the outer end faces in each case with connection plates which have a connection surface for lines which are fastened there.

Ein derartiger elektrischer Hochspannungs-Leistungsschalter, nämlich ein mit SF₆ gefüllter Druckgas-Leistungsschalter ist aus der Siemens-Druckschrift "SF₆-Leistungsschalter 3 AS1" (Bestellnummer E 122/1564-220) bekannt. Bei diesem bekannten Leistungsschalter werden die Anschlußflächen aus Ansätzen an den Anschlußplatten gebildet. Dies erfordert eine Vielzahl von unterschiedlich ausgeführten Anschlußplatten, da sowohl die Ausrichtung der Anschlußflächen in Abhängigkeit von der Schaltanlage wechseln kann, in die der Leistungsschalter eingebaut werden soll, als auch die Anordnung und die Bemessung der Befestigungsmittel auf den Anschlußflächen, mit denen dort die zum Schalter geführten elektrischen Leitungen, insbesondere Freiluftleitungen, befestigt werden. Da die Anschlußplatten ein den Innenraum der Unterbrechereinheiten abschließendes Teil bilden, muß somit jeder einzelne Schalter genau seiner Einsatzbestimmung nach gefertigt werden.Such an electrical high-voltage circuit breaker, namely a compressed gas circuit breaker filled with SF₆, is known from the Siemens publication “SF₆ circuit breaker 3 AS1” (order number E 122 / 1564-220). In this known circuit breaker, the connection surfaces are formed from approaches on the connection plates. This requires a large number of differently designed connection plates, since both the orientation of the connection surfaces can change depending on the switchgear in which the circuit breaker is to be installed, as well as the arrangement and dimensioning of the fastening means on the connection surfaces with which the switch guided electrical cables, especially outdoor cables, are attached. Since the connection plates form a part that closes the interior of the interrupter units, each individual switch must therefore be manufactured exactly according to its intended use.

Aus US-A-2 303 119 ist ein elektrischer Hochspannungs-Leistungsschalter bekannt, der dem Oberbegriff des Anspruchs 1 entspricht und wobei keine Umsetzung der Bauteile möglich ist.From US-A-2 303 119 an electrical high-voltage circuit breaker is known which corresponds to the preamble of claim 1 and in which no implementation of the components is possible.

Der vorliegenden Erfindung liegt die Aufgabe zugrunde, den Aufbau des Hochspannungs-Leistungsschalters durch eine andere Konstruktion der Anschlußplatten zu vereinfachen.The present invention has for its object to simplify the structure of the high-voltage circuit breaker by a different construction of the connection plates.

Diese Aufgabe wird dadurch gelöst, daß bei einem elektrischen Hochspannungs-Leistungsschalter der eingangs beschriebenen Art gemäß der Erfindung die Teilung bzw. Anordnung der entsprechenden Bohrungen in der Anschlußfläche und der Anschlußplatte eine umsetzbare Befestigung der Anschlußfläche an der Anschlußplatte ermöglicht.This object is achieved in that in an electrical high-voltage circuit breaker of the type described above According to the invention, the division or arrangement of the corresponding bores in the connection surface and the connection plate enables a practical attachment of the connection surface to the connection plate.

Die in Hinblick auf spätere Einbauarten des Leistungsschalters in der Schaltanlage allein zu variierende Anschlußfläche für die ankommenden bzw. abgehenden Leitungen ist also von der Anschlußplatte, die auch gleichzeitig Teil der Unterbrechereinheit ist und deren Innenraum verschließt, getrennt. Die Anschlußplatte ist somit ein Bauteil, der eindeutig der Unterbrechereinheit zugeordnet ist, so daß deren Fertigung, mithin auch die des Leistungsschalters und dessen Gasfüllung, vollkommen abgeschlossen werden kann, ohne daß zu entscheiden ist, welche Variante der Anschlußfläche an der Anschlußplatte angebracht werden muß. Diese Austauschbarkeit der Anschlußflächen untereinander ist möglich, weil die Bohrungen in der Anschlußplatte für die Aufnahme des Bauteils mit der Anschlußfläche in einem Randbereich liegen, der über den Außendurchmesser der Unterbrechereinheit hinausragt, so daß durch sie der Verschluß des Innenraums der Unterbrechereinheit nicht beeinträchtigt wird. Die Bohrungen und somit die Befestigungsmittel sind auch von außen her leicht zugänglich. Außerdem ist die Teilung bzw. Anordnung dieser Bohrungen so gewählt, daß die Anschlußfläche umsetzbar ist. Dadurch lassen sich praktisch alle Anbauvarianten erfassen.The connection surface for the incoming or outgoing lines, which can only be varied with regard to later types of installation of the circuit breaker in the switchgear, is therefore separate from the connection plate, which is also part of the interrupter unit and closes the interior thereof. The connection plate is thus a component that is clearly assigned to the interrupter unit, so that its manufacture, and consequently also that of the circuit breaker and its gas filling, can be completely completed without having to decide which variant of the connection surface has to be attached to the connection plate. This interchangeability of the connection surfaces is possible because the holes in the connection plate for receiving the component with the connection surface lie in an edge region which projects beyond the outside diameter of the interrupter unit, so that the closure of the interior of the interrupter unit is not impaired by them. The holes and thus the fasteners are easily accessible from the outside. In addition, the division or arrangement of these holes is chosen so that the connection surface can be implemented. This means that practically all attachment variants can be recorded.

Es ist besonders zweckmäßig, daß der Bauteil mit der Anschlußfläche um 180° umsetzbar ist. In diesem Fall liegt der Randbereich mit den Bohrungen nur auf entgegengesetzten Seiten der Anschlußplatte, so daß der senkrecht dazu stehende Bereich, der die Schlagweite zwischen benachbart angeordneten Schalterpolen bestimmt, gegenüber dem Außendurchmesser der Unterbrechereinheit nicht vergrößert ist.It is particularly expedient that the component with the connection surface can be implemented by 180 °. In this case, the edge area with the holes is only on opposite sides the connecting plate, so that the area perpendicular to it, which determines the pitch between adjacent switch poles, is not enlarged compared to the outer diameter of the interrupter unit.

Im folgenden sei die Erfindung noch anhand des in den Figuren 1 bis 3 der Zeichnung dargestellten Ausführungsbeispiels näher erläutert. Die Figur 1 zeigt eine Ansicht einer Unterbrechereinheit eines elektrischen Hochspannungs-Leistungsschalters. In der Figur 2 ist eine Aufsicht auf die Anschlußplatte und in Figur 3 eine seitliche Ansicht des Bauteils mit der Anschlußfläche dargestellt.The invention will be explained in more detail below with reference to the exemplary embodiment shown in FIGS. 1 to 3 of the drawing. FIG. 1 shows a view of an interrupter unit of an electrical high-voltage circuit breaker. FIG. 2 shows a top view of the connection plate and FIG. 3 shows a side view of the component with the connection surface.

Bei einem mit SF₆ gefüllten elektrischen Druckgas-Hochspannungs-Leistungsschalter ist die Unterbrechereinheit 1 auf einer Stützersäule 2 angeordnet. Sie ist an ihren Stirnseiten 3, 4 jeweils mit einer Anschlußplatte 5 gasdicht verschlossen. Dazu ist die Anschlußplatte 5 jeweils in geeigneter, nicht dargestellter Weise mit dem Befestigungsflansch 6 über Bohrungen 7 verbunden.In an electrical compressed gas high-voltage circuit breaker filled with SF₆, the interrupter unit 1 is arranged on a support column 2. It is closed gas-tight at its end faces 3, 4 with a connecting plate 5. For this purpose, the connection plate 5 is connected in a suitable manner, not shown, to the mounting flange 6 via bores 7.

Die Anschlußplatte 5 enthält weiterhin auf einem Kreisumfang mit gleichmäßiger Teilung angeordnete Bohrungen 8. Diese liegen jeweils in einem Randbereich 9, der jeweils einen Kreisbogenabschnitt bildet und auf zwei gegenüber liegenden Seiten der Anschlußplatte 5 vorgesehen ist, derart, daß er jeweils über den, durch Pfeile angedeuteten Außendurchmesser 11 der Unterbrechereinheit 1 hinausragt. Die seitlichen Kanten 10 der Randbereiche 9 sind abgerundet an diesen Außendurchmesser 11 herangeführt, so daß in dem senkrecht zu den Randbereichen 9 stehenden Bereich der Anlageplatte 5 der Außendurchmesser 11 deren Abmessungen bestimmt. Dadurch wird die Schlagweite zwischen zwei nebeneinander liegend angeordenten Polen des Leistungsschalters infolge der durch die separate Ausführung des Bauteils mit der Anschlußfläche erforderlich werdenden zusätzlichen Befestigungsmittels nicht vergrößert.The connection plate 5 also contains holes 8 arranged on a circular circumference with uniform division. These lie in each case in an edge region 9, which in each case forms an arcuate section and is provided on two opposite sides of the connection plate 5, in such a way that it is in each case by arrows indicated outer diameter 11 of the interrupter unit 1 protrudes. The lateral edges 10 of the edge regions 9 are rounded off to this outer diameter 11, so that in the area of the contact plate 5 which is perpendicular to the edge regions 9, the outer diameter 11 determines its dimensions. As a result, the distance between two poles of the circuit breaker which are arranged next to one another is not increased as a result of the additional fastening means which are required due to the separate design of the component with the connection surface.

Der separate Bauteil 12 mit der Anschlußfläche 13 und den auf dieser vorgesehenen Befestigungsbohrungen 14 für die nicht dargestellten, anzuschließenden Leitungen weist einen Flanschteil 15 auf, der ebenfalls einen Kreisbogenabschnitt 16 bildet. Dieser Flanschteil 15 am Bauteil 12 entspricht dem Randbereich 9 an der Anschlußplatte 5. In gleicher Weise wie dort die Bohrungen 8 sind auf dem Flanschteil 15 Bohrungen 17 angeordnet, die mit entsprechender gleichmäßiger Teilung aus dem gleichen Kreisumfang wie die Bohrungen 8 liegen.The separate component 12 with the connecting surface 13 and the fastening bores 14 provided thereon for the lines (not shown) to be connected has a flange part 15 which likewise forms an arcuate section 16. This flange part 15 on the component 12 corresponds to the edge area 9 on the connection plate 5. In the same way as the holes 8, holes 17 are arranged on the flange part 15, which lie with a corresponding uniform division from the same circumference as the holes 8.

Der separate Bauteil 12 mit der Anschlußfläche 13 wird nun mit einem der beiden Randbereiche 9 der Anschlußplatte 5 über Bolzen 18 verbunden. Der Bauteil 12 ist also um 180° umsetzbar. Bei dem gezeigten Ausführungsbeispiel liegt der Bauteil 12 an der unteren Stirnseite 4 der Unterbrechereinheit 1 auf der rechten Seite und an der oberen Stirnseite 3 der Unterbrechereinheit 1 auf der linken Seite.The separate component 12 with the connection surface 13 is now connected to one of the two edge regions 9 of the connection plate 5 via bolts 18. The component 12 can thus be implemented by 180 °. In the exemplary embodiment shown, the component 12 lies on the lower end face 4 of the interrupter unit 1 on the right side and on the upper end face 3 of the interrupter unit 1 on the left side.

Der Bauteil 12 mit der Anschlußfläche 13 kann jederzeit an der gasdicht verschlossenen Unterbrechereinheit 1 des elektrischen Hochspannungs-Leistungsschalters angeschlossen oder wieder abgenommen werden, ohne daß dies dem betriebsbereiten Zustand des gasgefüllten Leistungsschalters beeinträchtigt, weil dazu die Unterbrechereinheit 1 nicht geöffnet werden muß. Dies ermöglicht eine leichte Anpassung der Anschlußfläche 13 an geänderte Einbaugegebenheiten, sowohl hinsichtlich ihrer Lage, da eine Umsetzbarkeit um 180° gegeben ist, als auch hinsichtlich der Anordnung und Bemessung der in der Anschlußfläche 13 vorgesehenen Befestigungsbohrungen 14 zur Aufnahme der Befestigungsmittel, mit denen die Verbindung zu den ankommenden bzw. abgehenden, nicht dargestellten Freileitungen vorgenommen wird. Bei einer Änderung der Erfordernisse hinsichtlich Anordnung und Bemessung dieser Befestigungsbohrungen 14 auf der Anschlußfläche 13, z. B. infolge anderer Normen, kann das Auswechseln der Bauteile 12 also in einfachster Weise vorgenommen werden.The component 12 with the connection surface 13 can be connected to the gas-tight interrupter unit 1 of the electrical high-voltage circuit breaker or removed again at any time without this affecting the operational state of the gas-filled circuit breaker because the interrupter unit 1 does not have to be opened for this. This enables the connection surface 13 to be easily adapted to changed installation conditions, both with regard to its position, since it can be implemented by 180 °, and also with regard to the arrangement and dimensioning of the fastening bores 14 provided in the connection surface 13 for receiving the fastening means with which the connection to the incoming or outgoing overhead lines, not shown. When changing the requirements with regard to the arrangement and dimensioning of these mounting holes 14 on the connecting surface 13, for. B. due to other standards, the replacement of the components 12 can be made in the simplest way.
