Abstract

A high-voltage compressed-gas circuit breaker having terminal plates with a contact face for incoming cables. The position of these contact faces and the attachment devices on the contact faces for the connection of the cables varies according to the form of installation given in the switching equipment. The contact faces are formed as a separate part from the terminal plate. On both the separate part and the terminal plate, bores for connection of the part and the plate are provided which do not affect the sealing by the terminal plates of the interior of the interrupter unit at its outer end faces. The bores permit an attachment of the separate part to the contact face in either a first position, or a second position which is rotated by 90 DEG from said first position.

Description

Die Erfindung bezieht sich auf einen elektrischen Hochspannungs-Leistungsschalter, insbesondere Druckgas-Leistungsschalter, dessen Unterbrechereinheiten an den äußeren Stirnflächen jeweils mit Anschlußplatten abgeschlossen sind, die jeweils eine Anschlußfläche für Leitungen aufweisen, die dort befestigt werden, wobei jede Anschlußfläche als separater Bauteil gegenüber der jeweiligen Anschlußplatte ausgebildet ist, und sowohl an jedem Bauteil als auch an jeder Anschlußplatte Bohrungen zur Aufnahme von Befestigungsmitteln vorgesehen sind, welche jeden Bauteil mit der jeweiligen Anschlußplatte verbinden, ohne daß die Bohrungen in jeder Anschlußplatte den Verschluß des Innenraums der Unterbrechereinheit beeinträchtigen.The invention relates to an electrical high-voltage circuit breaker, in particular pressurized gas circuit breaker, the interrupter units of which are terminated on the outer end faces with connection plates, each having a connection surface for lines which are fastened there, each connection surface as a separate component with respect to the respective Connection plate is formed, and both on each component and on each connection plate holes for receiving fasteners are provided, which connect each component to the respective connection plate without the holes in each connection plate impair the closure of the interior of the interrupter unit.

Ein derartiger elektrischer Hochspannungs-Leistungsschalter ist aus der US-A 2 660 631 bekannt. Der dort beschriebene Hochspannungsschalter weist an seinen Unterbrechereinheiten jeweils Anschlußplatten und separate Anschlußflächen zur Befestigung von Leitungen auf. In Anschlußplatten und Anschlußflächen sind Bohrungen zur Aufnahme von Befestigungsmitteln vorgesehen. Die elektrische Kontaktierung der Anschlußflächen erfolgt über die Kugeln eines Kugellagers, das der drehbaren Lagerung eines Kontaktmessers dient.Such an electrical high-voltage circuit breaker is known from US-A 2 660 631. The high-voltage switch described there has connection plates and separate connection surfaces for fastening lines on its interrupter units. Holes for receiving fasteners are provided in connection plates and connection surfaces. The contact surfaces are electrically contacted via the balls of a ball bearing, which is used for the rotatable mounting of a contact knife.

Außerdem ist aus der Siemens-Druckschrift "SF₆-Leistungsschalter 3 AS1" (Bestellnummer E 122/1564-220) ein mit SF₆ gefüllter Druckgas-Leistungsschalter bekannt, bei dem die Anschlußflächen aus Ansätzen an den Anschlußplatten gebildet sind. 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.In addition, from the Siemens publication "SF₆-circuit breaker 3 AS1" (order number E 122 / 1564-220) a pressurized gas circuit breaker filled with SF₆ is known, in which 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 assembly, in which the Circuit breaker is to be installed, as well as the arrangement and dimensioning of the fasteners on the connection surfaces with which the electrical leads to the switch, in particular outdoor cables, are fastened there. 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.

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.

Zur Lösung dieser Aufgabe ist bei einem elektrischen Hochspannungs-Leistungsschalter der eingangs beschriebenen Art vorgesehen, daß die Anordnung der entsprechenden Bohrungen auf jeder Anschlußplatte und jedem Bauteil eine um 90° umsetzbare Befestigung der jeweiligen Anschlußfläche an der jeweiligen Anschlußplatte ermöglicht.To solve this problem, it is provided in an electrical high-voltage circuit breaker of the type described in the introduction that the arrangement of the corresponding bores on each connection plate and each component enables the respective connection surface to be fastened to the respective connection plate by 90 °.

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 den Verschluß des Innenraums der Unterbrechereinheit nicht beeinträchtigen und von außen leicht zugänglich sind. Außerdem ist die Teilung bzw. Anordnung dieser Bohrungen so gewählt, daß jede Anschlußfläche um 90° gegenüber der jeweiligen Anschlußplatte umsetzbar ist. Dadurch lassen sich praktisch alle Anbauvariationen 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 bores in the connection plate for receiving the component with the connection surface do not impair the closure of the interior of the interrupter unit and are easily accessible from the outside. In addition, the division or arrangement of these holes is chosen so that each connection surface by 90 ° with respect to the respective connection plate is feasible. This means that practically all cultivation variations can be recorded.

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 teilweise geschnittene Ansicht einer Unterbrechereinheit eines elektrischen Hochspannungs-Leistungsschalters. In den Figuren 2 und 3 sind Ansichten eines Bauteils mit Anschlußfläche aus unterschiedlichen Richtungen 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 partially sectioned view of an interrupter unit of an electrical high-voltage circuit breaker. FIGS. 2 and 3 show views of a component with a connection surface from different directions.

Bei einem mit SF₆ gefüllten elektrischen Druckgas-Hochspannungs-Leistungsschalter ist die Unterbrechereinheit 1 auf einer Stützersäule 2 angeordnet. Die äußere Stirnfläche 3 der Unterbrechereinheit 1 ist mit einer Anschlußplatte 4 gasdicht verschlossen. Sie ist dazu mit dem Befestigungsflansch 5 der Unterbrechereinheit 1 in geeigneter Weise mit Bolzen 6 verbunden.In an electrical compressed gas high-voltage circuit breaker filled with SF₆, the interrupter unit 1 is arranged on a support column 2. The outer end face 3 of the interrupter unit 1 is closed gas-tight with a connecting plate 4. For this purpose, it is connected to the mounting flange 5 of the interrupter unit 1 in a suitable manner with bolts 6.

Die Anschlußplatte 4 enthält weiterhin auf einem Kreisumfang mit gleichmäßiger Teilung angeordnete Gewindebohrungen 7, die als Sacklöcher ausgebildet sind. Diese Gewindebohrungen 7 dienen zur Befestigung des gegenüber der Anschlußplatte 4 seperat ausgebildeten Bauteils 8 mit der Anschlußfläche 9. Dieser Bauteil 8 weist einen senkrecht zu der Anschlußfläche 9 stehenden Flansch 10 auf, in dem die Bohrungen 11 zur Befestigung an der Anschlußplatte 4 liegen. Diese Bohrungen 11 haben die gleiche Teilung und liegen auf dem gleichen Kreisumfang wie die Gewindebohrungen 7 in der Anschlußplatte 4. Die Teilung der Bohrungen 7 bzw. 11 ist so gewählt, daß die Anschlußfläche 9 auf der Anschlußplatte 4 um 90° umsetzbar ist. Der Bauteil 8 ist dann in der gewünschten Lage mit Schrauben 12 zu der Anschlußplatte 4 befestigt.The connection plate 4 further includes threaded holes 7 arranged on a circumference with a uniform pitch, which are designed as blind holes. These threaded holes 7 are used to fasten the component 8, which is formed separately from the connecting plate 4, to the connecting surface 9. This component 8 has a flange 10 which is perpendicular to the connecting surface 9 and in which the holes 11 are located for fastening to the connecting plate 4. These holes 11 have the same pitch and lie on the same circumference as the threaded holes 7 in the connection plate 4. The division of the holes 7 and 11 is selected so that the connection surface 9 on the connection plate 4 can be implemented by 90 °. The component 8 is then fastened in the desired position with screws 12 to the connection plate 4.

Der Bauteil 8 mit der Anschlußfläche 9 kann jederzeit an der gasdicht verschlossenen Unterbrechereinheit 1 des elektrischen Hochspannungs-Leistungsschalters angeschlossen oder wieder abgenommen werden, ohne daß dies den betriebsbereiten Zustand des gasgefüllten Leistungsschalters beeinträchtigt, weil dazu die Unterbrechereinheit 1 nicht geöffnet werden muß. Dies ermöglicht eine leichte Anpassung der Anschlußfläche 9 an geänderte Einbaugegebenheiten sowohl hinsichtlich ihrer Lage, da eine Umsetzbarkeit um 90° gegeben ist, als auch hinsichtlich der Anordnung und Bemessung der in der Anschlußfläche 9 vorgesehenen Befestigungsbohrungen 13 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 13 auf der Anschlußfläche 9, z. B. infolge anderer Normen, kann das Auswechseln der Bauteile 8 also in einfachster Weise vorgenommen werden.The component 8 with the connection surface 9 can at any time on the gas-tight interrupter unit 1 of the electrical High-voltage circuit breakers are connected or removed again 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 easy adaptation of the connection surface 9 to changed installation conditions both with regard to its position, since it can be implemented by 90 °, and also with regard to the arrangement and dimensioning of the fastening bores 13 provided in the connection surface 9 for receiving the fastening means with which the connection to the incoming or outgoing overhead lines, not shown, is made. When changing the requirements with regard to the arrangement and dimensioning of these mounting holes 13 on the connecting surface 9, z. B. due to other standards, the replacement of the components 8 can be made in the simplest way.
