Description

Die Erfindung bezieht sich auf einen elektrischen Druckgas-Hochspannungs-Leistungsschalter, dessen in zumindest einer Unterbrechereinheit liegende Schaltkontakte von einem auf Erdpotential in einem Gestell unterhalb einer isolierenden Stützersäule angeordneten Antrieb bewegt werden, der die dafür erforderliche Kraft mittels eines in dem auf Erdpotential befindlichen Gestell liegenden Umlenkgetriebes und einer in der Stützersäule angeordneten Schaltstange aus Isolierstoff jeweils über Zwischengetriebe auf die beweglichen Schaltkontakte überträgt, und bei dem im Gasraum ein in einem gesonderten Gehäuse untergebrachtes Filter vorgesehen ist.The invention relates to an electrical compressed gas high-voltage circuit breaker whose switch contacts located in at least one interrupter unit are moved by a drive arranged at earth potential in a frame below an insulating support column, which drives the force required for this by means of a frame located at earth potential Deflection gear and a switching rod arranged in the support column made of insulating material each via intermediate gears on the movable switch contacts, and in which a filter housed in a separate housing is provided in the gas space.

Derartige elektrische Druckgas-Hochspannungs-Leistungsschalter sind aus der Siemens-Zeitschrift 1973, Seite 241 und 1977, Seite 268 bekannt. Bei diesen bekannten Druckgas-Hochspannungs-­Leistungsschaltern ist das Gehäuse mit dem Filter, das jeweils mit einer Brechplatte abgeschlossen ist, an den äußeren, insbesondere oberen Stirnseiten der Unterbrechereinheiten angeordnet. Diese Anordnung hat den Nachteil, daß das Gehäuse des Filters für das von Zeit zu Zeit erforderliche Auswechseln des darin liegenden Materials schlecht zugänglich ist.Such electrical compressed gas high-voltage circuit breakers are known from Siemens magazine 1973, page 241 and 1977, page 268. In these known compressed gas high-voltage circuit breakers, the housing with the filter, which is each terminated with a crushing plate, is arranged on the outer, in particular upper, end faces of the interrupter units. This arrangement has the disadvantage that the housing of the filter is difficult to access for the occasional replacement of the material therein.

Der Erfindung liegt die Aufgabe zugrunde, das Gehäuse mit dem Filtermaterial bei einem elektrischen Druckgas-Hochspannunbgs-­Leistungsschalter in leicht zugänglicher Weise anzuordnen, ohne daß dadurch die Filterwirkung des Materials beeinträchtigt wird.The invention has for its object to arrange the housing with the filter material in an electrical compressed gas high-voltage circuit breaker in an easily accessible manner without the filter effect of the material being impaired.

Zur Lösung dieser Aufgabe ist bei einem elektrischen Druckgas-Hochspannungs-Leistungsschalter der eingangs beschriebenen Art gemäß der Erfindung das Gehäuse für den Filter unten am Gehäuse des Umlenkgetriebes befestigt.To achieve this object, the housing for the filter is attached to the bottom of the housing of the deflection gear in an electrical compressed gas high-voltage circuit breaker of the type described in the introduction according to the invention.

Dadurch befindet sich das Gehäuse mit dem Filtermaterial auf Erdpotential und ist in dem unterhalb der Stützersäule befindlichen Gestell des Schalters sehr leicht zugänglich, so daß ein Austausch des Materials, nachdem dieses durch Aufnahme von Zersetzungsprodukten des Druckgases, wie diese bei Schalthandlungen infolge des Lichtbogens auftreten können, oder von Feuchtigkeit unbrauchbar geworden ist, keine Schwierigkeiten bereitet.As a result, the housing with the filter material is at earth potential and is very easily accessible in the frame of the switch located below the support column, so that an exchange of the material after this by absorption of decomposition products of the compressed gas, as can occur during switching operations as a result of the arc , or has become unusable from moisture, presents no difficulties.

Weiterhin empfiehlt es sich, im Gehäuse ein perforiertes Blech vorzusehen. Dieses legt das Material des Filters innerhalb des Gehäuses fest, ohne daß dadurch der Zutritt des Schaltgases zu dem Material unterbunden wird. Das Material des Filters kann sich somit nicht bei einem Transport des Schalters in unerwünschter Weise verlagern.It is also advisable to provide a perforated sheet in the housing. This defines the material of the filter within the housing without preventing the switching gas from entering the material. The material of the filter cannot shift in an undesirable manner when the switch is transported.

Ferner ist es vorteilhaft, zur Kombination des Gehäuses des Filters mit einer Brechplatte, daß im Gehäuse des Filters mittig ein vertikal verlaufendes, perforiertes Rohr vorgesehen ist, wobei das Material des Filters zwischen dem Rohr und den seitlichen Wänden des Gehäuses liegt und daß die Brechplatte das Gehäuse im Bereich unterhalb des Rohres abschließt. Auf diese Weise liegt die Brechplatte in direkter Verbindung mit dem Gasraum des Hochspannungs-Leistungsschalters und kann somit auch unmittelbar auf in diesem auftretende Druck­erhöhungen in unzulässiger Höhe ansprechen.Furthermore, it is advantageous to combine the housing of the filter with a crushing plate that a vertically extending perforated tube is provided in the center of the filter housing, the material of the filter between the tube and the side walls of the housing and that the crushing plate Housing in the area below the pipe. In this way, the crushing plate is in direct connection with the gas space of the high-voltage circuit breaker and can therefore also respond directly to pressure increases occurring in an unacceptable amount.

Es ist außerdem zweckmäßig, bei hoher Aufstellung des Schalters, z. B. auf Stielen, unterhalb der Brechplatte einen Gehäusedeckel anzuordnen, der den Raum unterhalb der Brech­platte überdeckt und zumindest eine nach oben gerichtete Öffnung am Umfang des Gehäuses aufweist. Dadurch wird, für den Fall des Ansprechens der Brechplatte gewährleistet, daß die bei Zerstörung der Brechplatte von dem Gasraum des elektrischen Druckgas-Hochspannungs-Leistungsschalters in die Umgebung ausgestoßenen heißen Gase nach oben umgeleitet werden, so daß eine Gefährdung von sich zufällig unterhalb des Schalters befindlichen Personen vermieden wird.It is also useful, with the switch in a high position, e.g. B. on stems to arrange a housing cover below the crushing plate, which covers the space below the crushing plate and has at least one upward opening on the circumference of the housing. This ensures, in the event of the response of the crushing plate, that the hot gases expelled from the gas space of the electrical compressed gas high-voltage circuit breaker into the environment when the crushing plate is destroyed are diverted upward, so that there is a risk of accidentally being below the switch People is avoided.

Im folgenden sei die Erfindung noch anhand der in den Figuren 1 und 2 der Zeichnung dargestellten Ausführungsbeispiele näher erläutert. Fig. 1 zeigt einen Teilschnitt durch das auf Erdpotential liegende Gestell eines elektrischen Druckgas-­Hochspannungs-Leistungsschalters. In Fig. 2 ist eine abgewandelte Ausführungsform des Filtergehäuses dargestellt.The invention will be explained in more detail below with reference to the exemplary embodiments shown in FIGS. 1 and 2 of the drawing. Fig. 1 shows a partial section through the frame at ground potential of an electrical compressed gas high-voltage circuit breaker. 2 shows a modified embodiment of the filter housing.

Bei einem elektrischen Druckgas-Hochspannungs-Leistungsschalter dient zur Betätigung der in den nicht dargestellten Unterbrechereinheiten liegenden Schaltkontakte, die jeweils über ein Zwischengetriebe erfolgt, eine innerhalb der Stützersäule 1 angeordnete Schaltstange 2 aus Isolierstoff, die den Abstand zwischen den nicht dargestellen, Hochspannungs­potential führenden Unterbrechereinheiten nebst Zwischen­getriebe und dem auf Erdpotential liegenden Gestell 3 des Schalters überbrückt. Dieses Gestell 3 trägt auch noch den nicht dargestellten Antrieb und die benötigten Steuermittel nebst Hydraulikspeicher.In the case of an electrical compressed gas high-voltage circuit breaker, a switching rod 2 made of insulating material, which is arranged within the support column 1 and serves to actuate the switch contacts located in the breaker units, not shown, which is in each case via an intermediate gear, and the distance between the breaker units, not shown, carrying high-voltage potential Intermediate gear and the frame 3 of the switch bridged to earth potential. This frame 3 also carries the drive, not shown, and the required control means, in addition to the hydraulic accumulator.

Die jeweils für die Schaltung erforderlichen Kräfte werden auf die Schaltstange 2 mit Hilfe eines mit dem nicht dargestellten Antrieb angetriebenen Umlenkgetriebes 4 übertragen, dessen Gehäuse 5 unmittelbar mit dem unteren Flansch 6 der Stützersäule 1 verbunden ist. Der innerhalb der Stützersäule 1 befindliche, mit SF₆ gefüllte Gasraum 7 ist mithin mit dem Innenraum des Gehäuses 5 verbunden. Außerdem ist unterhalb des Gehäuses 5 des Umlenkgetriebes 4 das Gehäuse 8 des Filters 9 befestigt. Dieses Gehäuse 8 enthält ein perforiertes Blech 10, unter dem das in Säckchen 11 angeordnete Material des Filters 9 liegt. Dieses ist somit durch das perforierte Blech 10 gegen ein unerwünschtes Verlagern geschützt, wenn der Schalter zu Montagezwecken in nicht vertikaler Ausrichtung transportiert wird.The forces required for the shift are transferred to the shift rod 2 with the aid of a reversing gear 4 driven by the drive (not shown), the housing 5 of which is connected directly to the lower flange 6 of the support column 1. The inside of the support column 1, filled with SF₆ gas space 7 is therefore connected to the interior of the housing 5. In addition, the housing 8 of the filter 9 is attached below the housing 5 of the deflection gear 4. This housing 8 contains a perforated sheet 10, under which the material of the filter 9 arranged in small bags 11 is located. This is thus protected by the perforated plate 10 against undesired displacement when the switch is transported in a non-vertical orientation for assembly purposes.

Die Festlegung des perforierten Bleches 10 innerhalb des Gehäuses 8 des Filters 9 kann dadurch vereinfacht werden, daß abweichend von der in Fig. 1 gezeigten Darstellung das perforierte Blech in den Bereich des Flansches 13 des Gehäuses 8 gelegt ist.The fixing of the perforated plate 10 within the housing 8 of the filter 9 can be simplified in that, differently from the illustration shown in FIG. 1, the perforated plate is placed in the region of the flange 13 of the housing 8.

Die Figur 2 zeigt ein etwas abgewandeltes Ausführungsbeispiel des Gehäuses 8 des Filters 9. Für gleiche Teile sind die gleichen Bezugszahlen beibehalten worden.FIG. 2 shows a somewhat modified embodiment of the housing 8 of the filter 9. The same reference numbers have been retained for the same parts.

Das Gehäuse 8 des Filters 9 ist bei diesem Ausführungsbeispiel unten mit der Brechplatte 14 verschlossen, die dazu dient, im Störungsfall die im wesentlichen aus Porzellan gebildeten Wände des Gasraumes des Druckgas-Hochspannungs-Leistungsschalters gegen eine unzulässige hohe Druckerhöhung zu schützen. In diesem Fall wird die Brechplatte 14 bei einem bestimmten vorgegebenen Innendruck zerstört, und die unter Druck stehenden Gase des Schalters werden in die Umgebung abgeleitet. Zu deren Umlenkung ist unterhalb der Brechplatte 14 ein Gehäusedeckel 15 angeordnet, der unterhalb der Brechplatte 14 die Öffnung 16 im Gehäuse 8 überdeckt und nur eine nach oben gerichtete Öffnung 17 am Umfang des Gehäuses 8 aufweist. Die durch die Brechplatte 14 austretenden heißen Schaltgase werden dadurch unschädlich nach oben abgeleitet. Eine Gefährdung von Personen ist somit verhindert.In this exemplary embodiment, the housing 8 of the filter 9 is closed at the bottom with the crushing plate 14, which serves to protect the walls of the gas space of the compressed gas high-voltage circuit breaker essentially made of porcelain in the event of a fault against an impermissibly high pressure increase. In this case, the crushing plate 14 is destroyed at a certain predetermined internal pressure, and the pressurized gases of the switch are discharged into the environment. To deflect them, a housing cover 15 is arranged below the crushing plate 14, which covers the opening 16 in the housing 8 below the crushing plate 14 and has only one upwardly directed opening 17 on the circumference of the housing 8. The hot switching gases escaping through the crushing plate 14 are thereby harmlessly discharged upwards. This prevents people from being endangered.

Um den Raum oberhalb der Brechplatte 14 für den Zutritt der Schaltgase freizuhalten, ist in dem Gehäuse 8 des Filters 9 mittig ein vertikal verlaufendes perforiertes Rohr 18 vorgesehen. Das in Säckchen 11 befindliche Material des Filters 9 liegt zwischen dem Rohr 18 und den seitlichen Wänden 19 des Gehäuses 8. Außerdem ist der Innenraum des Gehäuses 8 noch durch das innerhalb des Bereiches des Flansches 13 des Gehäuses 8 angeordnete perforierte Blech 10 mit einer größeren Zentralöffnung 12 verschlossen. Dieses legt auch das Rohr 18 fest. Auch bei dieser Ausführungsform kann der Druckgas-­Hochspannungs-Leistungsschalter in unterschiedlichen Lagen transportiert werden.In order to keep the space above the crushing plate 14 free for the switching gases to enter, a vertically running perforated tube 18 is provided in the center of the housing 8 of the filter 9. The material of the filter 9 located in the bag 11 lies between the tube 18 and the side walls 19 of the housing 8. In addition, the interior of the housing 8 is also provided with a larger central opening by the perforated sheet metal 10 arranged within the region of the flange 13 of the housing 8 12 closed. This also defines the tube 18. In this embodiment too, the compressed gas high-voltage circuit breaker can be transported in different positions.
