Description
Hetallgekapselte, isoliergasgefüllte SchaltanlageMetal-encapsulated, insulating gas-filled switchgear
Die Neuerung betrifft eine metallgekapselte, isoliergasgefüllte Schaltanlage, deren Geräte und Leitungen sich in aneinandergeflanschten Gehäusen befinden.The innovation concerns a metal-encapsulated, insulating gas-filled one Switchgear whose devices and lines are flanged together Housings are located.
Die gasdichte Verbindung einzelner Anlagengehäuse wie z.E. Sammelschienengehäuse mit Schaltzellengehäuse erfolgt zweckmäßigerweise durch Flanschverbindungen. Die Verbindung der an den Gehäusen vorgesehenen Flansche wird bei den bekannten gasisolierten Hochspannungsschaltanlagen durch Verschrauben oder Verschweißen hergestellt. Diese Verbindungsformen sind relativ aufwendig und zeitraubend. The gas-tight connection of individual system housings such as Busbar housing with switch cell housing is expedient through flange connections. The connection of the flanges provided on the housings is used in the known Gas-insulated high-voltage switchgear manufactured by screwing or welding. These forms of connection are relatively complex and time-consuming.
Der Neuerung lag die Aufgabe zugrunde, eine einfachere Verbindung für die Flansche gasisolierter Schaltanlagengehäuse zu schaffen. Diese Aufgabe wurde durch die im Schutzanspruch aufgeführten Merkmale gelöst.The innovation was based on the task of creating a simpler connection for the flanges of gas-insulated switchgear housings to accomplish. This problem was solved by the features listed in the protection claim.
Mit Hilfe spannbarer, V-förmiger Bandschellen läßt sich eine schnelle, einfach durchzuführende Verbindung für gasisolierte Schaltanlagengehäuse herstellen. Dadurch entfällt das zeitraubende Anbringen von Schraub- oder Schweißverbindungen. With the help of tensionable, V-shaped band clamps, a quick, easy-to-use connection for gas-insulated Manufacture switchgear enclosures. This eliminates the time-consuming attachment of screw or welded connections.
Die Neuerung wird bevorzugt bei Mittelspannungs-Schaltanlagen angewendet, die aus relativ dünnen Blechwänden mit Blechstärken um 2 mm gefertigt werden. Dabei sind die zu verbindenden Schaltanlagengehäuse vorzugsweise mit Bördelflansche versehen.The innovation is preferred for medium-voltage switchgear used, which are made of relatively thin sheet metal walls with sheet thicknesses of 2 mm. The ones to be connected are here Switchgear housing preferably provided with flanged flanges.

Als Dichtmittel dient ein zwischen den Flanschen befindlicher gummielastischer Dichtring.A sealant located between the flanges serves as a sealant rubber-elastic sealing ring.
Die Neuerung wird anhand eines Ausführungsbeispieles erläutert.The innovation is explained using an exemplary embodiment.
Fig. 1 zeigt in Explosionsdarstellung zwei metallgekapselte Schaltanlagengehäuse, z.B. Schaltzelle 1 und Sammelschienenkasten 2 vor der Verbindung, während Fig. 2 die Verbindungsanordnung im Schnitt zeigt.Fig. 1 shows an exploded view of two metal-encapsulated Switchgear housing, e.g. switch cell 1 and busbar box 2 before the connection, while FIG. 2 shows the connection arrangement in section.
Die Kapselungsöffnungen besitzen kreisförmige Flansche 3, 4, deren mechanisch feste Verbindung durch eine im Profil V-förmige, spannbare Bandschelle 5 erfolgt. Die Bandschelle 5 ist an einer Stelle offen und an den Enden mit sich gegenüberliegenden, abgewinkelten Ösen 9 ausgestattet. Nach Anlegen der Schelle 5 wird die Spannvorrichtung - bestehend aus Schraubenmutter 7 und durch die Ösen 9 geführte Schraube 6 - angezogen, bis die Bandschelle 5 die Flansche 3, 4 aufgrund beidseitiger Keilwirkung dicht und fest zusammenpreßt.The encapsulation openings have circular flanges 3, 4, their mechanically fixed connection is made by a tensionable band clamp 5 with a V-shaped profile. The band clamp 5 is on one Place open and angled at the ends Eyelets 9 fitted. After applying the clamp 5, the clamping device - consisting of nut 7 and Screw 6 guided through the eyelets 9 - tightened until the band clamp 5 hits the flanges 3, 4 due to the bilateral wedge effect press tightly and firmly together.
Als Dichtmittel befindet sich zwischen den Flanschflächen ein nur in Fig. 2 eingezeichneter, vorzugsweise T-förmiger, aus gummielastischem Material hergestellter Dichtring δ.A sealant is located between the flange surfaces Only in Fig. 2 drawn, preferably T-shaped, made of rubber-elastic material sealing ring δ.
