Abstract

A phase conductor arrangement for an electricity transmission device has an electroconductive main member. The electroconductive main member extends along a main axis. A substantially slit-shaped opening extends along the main member. The main member is a hollow cylinder, and the opening extends along an outer wall of the hollow cylinder. The outer wall opposite the opening is closed.

First claim

The invention claimed is:

1. A phase conductor arrangement for an electrical energy transmission device, the phase conductor arrangement comprising:
an electrically conductive base body being a hollow cylinder extending along a main axis;
said hollow cylinder having a peripheral wall formed with a strip-shaped cut-out and a closed peripheral wall disposed opposite said cut-out; and
said peripheral wall being formed with a profiled structure on an inner peripheral face thereof for increasing a surface area of said peripheral wall.

2. The phase conductor arrangement according to claim 1 , wherein said cut-out extends continuously along said base body.

3. The phase conductor arrangement according to claim 1 , wherein said hollow cylinder is formed with a groove that is accessible via said cut-out formed in said hollow cylinder.

4. The phase conductor arrangement according to claim 1 , wherein said cut-out has a shorter extension than said groove in a direction transversely to the main direction.

5. The phase conductor arrangement according to claim 1 , wherein said base body is an angle-rigid body.

6. The phase conductor arrangement according to claim 1 , wherein said base body has an end-face side contacting surface being an annular segment.

7. The phase conductor arrangement according to claim 6 , which comprises a tensioning device having elements distributed about an end face of said base body.

8. The phase conductor arrangement according to claim 1 , which comprises a central tensioning device in an end face of said base body.

9. The phase conductor arrangement according to claim 8 , wherein said central tensioning device is arranged on a web that is encompassed by said base body.

10. The phase conductor arrangement according to claim 9 , wherein said web lies diametrically opposite said cut-out.

11. The phase conductor arrangement according to claim 6 , wherein said cut-out is delimited by free ends of said annular segment.

12. The phase conductor arrangement according to claim 1 , wherein said cut-out extends parallel with said main axis.

13. An electrical energy transmission device that is insulated by pressurized fluid, the electrical energy transmission device comprising a phase conductor arrangement according to claim 1 .

14. The phase conductor arrangement according to claim 1 , further comprising:
a plurality of webs protruding out of a cylindrical inner peripheral face of said base and protruding radially inward in a direction of said main axis; and
a tensioning device having elements distributed about an end face of said base body; and
said base body having an end-face side contacting surface formed as an annular segment.
