Abstract

A cover unit for a converter head of a high-voltage converter device includes a flat, preferably planar, cover element and an RIV shielding device peripherally surrounding the cover element for shielding radio interference voltage. The RIV shielding device is formed by a plurality of RIV shielding elements distributed peripherally on the edge of the cover element. The RIV shielding elements each have a substantially cylindrical shape, in particular a capsule shape. A corresponding converter head and a corresponding high-voltage converter device are also provided.

First claim

The invention claimed is:

1. A cover unit for a converter head of a high-voltage converter device, the cover unit comprising:
a flat cover element having an edge; and
an RIV shielding device peripherally surrounding said cover element for shielding radio interference voltage;
said RIV shielding device being formed of a plurality of RIV shielding elements each having a cylindrical shape, said plurality of RIV shielding elements being distributed peripherally on said edge of said cover element.

2. The cover unit according to claim 1 , wherein said cover element is planar, and said plurality of RIV shielding elements each having a capsule shape.

3. The cover unit according to claim 1 , wherein said plurality of RIV shielding elements are each mounted on said cover element and configured to be repositioned or rotated.

4. The cover unit according to claim 1 , which further comprises at least one attachment structure disposed at said edge of said cover element.

5. The cover unit according to claim 4 , wherein said at least one attachment structure is an opening or an eye structure.

6. The cover unit according to claim 4 , which further comprises at least one attachment lug disposed at said edge of said cover element.

7. The cover unit according to claim 6 , which further comprises at least one further RIV shielding element for shielding radio interference voltage, said at least one further RIV shielding element disposed at an edge of an attachment lug or at an edge of at least one of a plurality of attachment lugs.

8. The cover unit according to claim 6 , wherein said plurality of RIV shielding elements are configured to be repositioned to:
shield said cover element in a first configuration, and expose at least one of said at least one attachment structure or said at least one attachment lug for ease of handling in a second configuration.

9. The cover unit according to claim 1 , wherein:
said cover element has a rectangular base area;
said plurality of RIV shielding elements are attached to sides of said base area; and
said plurality of RIV shielding elements, when in use as said RIV shielding device, extend along said sides of said base area.

10. The cover unit according to claim 9 , wherein said base area is square.

11. A converter head for a high-voltage converter device, the converter head comprising:
a cover unit according to claim 1 .

12. A high-voltage converter device, comprising:
a base;
a converter head according to claim 11 ; and
a support insulator disposed between said base and said converter head.

13. The high-voltage converter device according to claim 12 , wherein said base includes attachment structures.
