Description

Schaltzelle für''öiceännungszwecke Die Erfindung betrifft eine besondere Ausbildung der Schutzdecken in einer Hochspannungssclialtzelle. Switching cell for oil change purposes The invention relates to a special design of the protective covers in a high-voltage cell.

In der Fig. i ist eine Schaltzelle für Hochspannungszwecke der üblichen Bauart dargestellt. i und 2 sind zwei SammeIschienensysteme, von denen über Durchführungen _3 und a der Strom zu den Trennschaltern 5 und 6 eleitet wird. ; ist der Leistungsschalter,' S der Kabeltrennschalter. In derartigen Schaltzellen mußten zum Schutze -gegen die Sammelschienen Schutzdecken 9 und i o angeordnet werden, die meist dachförmig ausgebildet waren. Die Durchführungen 3 und ,f gehen durch diese Schutzdecken hindurch.In FIG. I, a switch cell for high-voltage purposes is the usual one Design shown. i and 2 are two busbar systems, one of which has bushings _3 and a the current is routed to the disconnectors 5 and 6. ; is the breaker, ' S the cable disconnect switch. In such switching cells had to protect against the Busbars protective covers 9 and i o are arranged, which are usually roof-shaped was. The bushings 3 and 3, f go through these protective covers.

Gemäß der Erfindung wird die Schutzdecke derartig ausgebildet, dar sie umgekehrt dachförmig in der Schaltzelle angeordnet ist. Ein Ausführungsbeispiel der Erfindung ist in Fig. 2 dargestellt. In dieser Figur sind wieder i und 2 die Sammelschien.ensysteme, 9 und i o sind die gemäß der Erfindung umgekehrt dachförmig angeordneten Schutzdecken. Damit man den Zustand der Sammelschienen von unten beobachten kann, sind weiter gemäß der Erfindung die Schutzdecken teilweise durchsichtig ausgebildet, in der Fig.2 bei i i und 12. Dieser Teil der Schutzdecken kann z. B. aus Drahtglas oder ähnlichem bestehen. 13 und 14 sind Trennschalter, die zugleich als Durchführungsisolatoren ausgebildet sein können.According to the invention, the protective cover is designed in such a way that it is arranged in an inverted roof shape in the switchgear cubicle. An embodiment of the invention is shown in FIG. In this figure, i and 2 are again the busbar systems, 9 and io are the protective covers arranged in a roof-shaped manner according to the invention. In order to be able to observe the state of the busbars from below, the protective covers are also partially transparent in accordance with the invention, in FIG. 2 at ii and 12. This part of the protective covers can e.g. B. made of wired glass or the like. 13 and 14 are disconnectors, which can also be designed as bushing insulators.

Die umgekehrt dachförmige Gestaltung der Schutzplatten hat den Vorteil, dar- die im Innern der Zellen aufsteigenden heißen Gase sofort nach aul5en von den Sammelschienen abgelenkt werden, ohne daß sie durch Fangräume zurückgehalten werden, wie dies bisher bei der dachförmigen Ausbildung der Decken der Fall war. Die Schutzplatte bietet weiter bei Lichtbogenentstehung an den Sammelschienen einen guten Schutz. für das Bedienungspersonal der Schaltzelle. Bei Entstehung von Lichtbögen an den Trennschaltern unterhalb der Decke wird weiter verhütet, daß die unter der Decke entstehenden heißen Gase finit dem Lichtbogen nach unten zu geleitet werden und das Bedienungspersonal gefährden.The reverse roof-shaped design of the protective plates has the advantage of the hot gases rising inside the cells immediately to the outside of the Busbars are deflected without being held back by trapping spaces, as was previously the case with the roof-shaped design of the ceilings. The protective plate also provides good protection in the event of an arcing on the busbars. for the operators of the switchgear cubicle. If arcing occurs on the Circuit breakers below the ceiling will further prevent those below the ceiling resulting hot gases are finitely guided down the arc and endanger the operating personnel.
