Description
Sammelschiene für Hochspannungsanlagen. Es ist bekannt, die Sammelschienen elek trischer Schaltanlagen an isolierten Trag seilen in ähnlicher Weise aufzuhängen, wie es bei der sogenannten Vielfachaufhängung des Fahrdrahtes elektrischer Bahnen üblich ist. Die Sammelschiene muss dabei in sich starr sein, hängt aber frei und wird gegen seitliche ,Schwingungen durch die ebenfalls starren Abzweigleitungen geschützt:.
Bei Anlagen von 100 000 Volt und dar über würde eine derartige Anordnung wegen der vielen unter Spannung stehenden Teile (Schiene, Tragseil, Hängedrähte) zu viel Strahlungsverluste verursachen. Dies wird bei der Anordnung nach der Erfindung ver mieden.
Darnach ist die Sammelschiene selbst ein Seil und wird zwischen zwei festen Stütz punkten, an denen sie durch Abspannkörper isoliert ist, ,ausgespannt. Auf diese Weise werden weitere spannungführende Zwischen glieder vermieden und die Strahlungsver luste auf ein Mindestmass gebracht. Bei Ver wendung eines dünneren Seils lassen sich, wie Fig. 1 zeigt, die Strahlungsverluste da durch vermindern, Jass man über das Seil a, das zwischen den Stützpunkten b, c an Ab- spannketten d ausgespannt ist, ein Rohr e schiebt; an dieses werden dann .die Abzwei gengen angeschlossen.
Um den Durchhang des Sammelschienen- s ei il s a auell ohne übergeschobenes Rohr bei verschiedenen Raumtemperaturen konstant zu halten, kann man es mit einem Dehnungs ausgleich versehen.
Beispielsweise kann man gemäss Fig. 2 in bekannter Weise an den einen der beiden Abspannisolatoren über ein Seilstück und eine Rolle f ein Ausgleichge- wicht g anhängen.
Ist die Sammelschiene lang, so kann man ihren Durchhäng dadurch verkleinern, dass man sie zwischen den festen Endpunkten an weiteren Stellen, z. B. wie in Fig. 3 darge stellt, an Hängeketten h isoliert aufhängt.
Die Abzweigungen, die von den Sammel schienen a nach den Schaltern und Apparaten führen, können ebenfalls Seile sein.
Busbar for high voltage systems. It is known to hang the busbars elec tric switchgear on insulated support ropes in a similar manner, as is common in the so-called multiple suspension of the contact wire of electrical railways. The busbar must be rigid in itself, but hangs freely and is protected against lateral vibrations by the branch lines, which are also rigid.
In systems of 100,000 volts and above, such an arrangement would cause too much radiation losses because of the many parts under voltage (rail, support cable, hanging wires). This is avoided ver in the arrangement according to the invention.
According to this, the busbar itself is a rope and is stretched between two fixed support points at which it is isolated by anchoring body. In this way, further live links are avoided and radiation losses are kept to a minimum. When using a thinner rope, as FIG. 1 shows, the radiation losses can be reduced by sliding a tube e over the rope a, which is stretched between the support points b, c on guy chains d; The branches are then connected to this.
In order to keep the sag of the busbar constant at different room temperatures without the tube being pushed over, it can be provided with an expansion compensation.
For example, according to FIG. 2, a counterweight g can be attached in a known manner to one of the two guy insulators via a piece of rope and a pulley f.
If the busbar is long, you can reduce its sag by placing it between the fixed end points at other points, e.g. B. as in Fig. 3 Darge, hangs isolated on hanging chains h.
The branches that lead from the busbars a to the switches and apparatus can also be ropes.
