Abstract

An electrical installation has a container which encloses high-voltage components. The electrical installation can be fitted inexpensively and quickly, and at the same time provide sufficient cooling of the high-voltage components. A control room with control elements and/or display elements of the electrical installation and a cool room with a cooling device for at least one of the high-voltage components are disposed in the interior of the container.

Claims

1. An electrical installation, comprising:

high-voltage components containing at least one phase module having a series circuit of submodules, each of said submodules having two connecting terminals, an energy store and a power semiconductor circuit connected in parallel with said energy store, said power semiconductor circuit having two turn-off power switches disposed in series with one another; and

a container enclosing said high-voltage components, said container containing an interior having a control room with at least one of control elements and display elements for the electrical installation and a cooling room with a cooling device for at least one of said high-voltage components.

2. The electrical installation according to claim 1, wherein said control room has a sealable access from outside said container.

3. The electrical installation according to claim 1, wherein said cooling room has a sealable access from outside said container.

4. The electrical installation according to claim 1, further comprising a high-voltage room inside said container which contains said high-voltage components.

5. The electrical installation according to claim 4, wherein said high-voltage room has at least one sealable access from outside said container.

6. The electrical installation according to claim 1, wherein said container has a wall that is at least partially soundproofed.

7. The electrical installation according to claim 6, wherein said wall at least partially has at least one of thermal insulation and insulation from electromagnetic radiation.

8. The electrical installation according to claim 6, wherein said wall is at least partially in double-wall form.

9. The electrical installation according to claim 6, wherein said wall has a soundproofing layer at least in subregions.

10. The electrical installation according to claim 1, wherein said container contains at least one inductor.

11. The electrical installation according to claim 10, wherein said inductor is water-cooled.

12. The electrical installation according to claims 6, wherein said container has, on an outside of said wall, externally accessible high-voltage connections for connecting the electrical installation to one of a transmission network and a distribution network.

13. The electrical installation according to claim 12, wherein said high-voltage connections are in a form of part of a plug connection.

14. The electrical installation according to claim 1, wherein said container has connections for a supply of a cooling fluid.

15. The electrical installation according to claim 1, wherein said power semiconductor circuit and said energy store form a full-bridge circuit.

16. The electrical installation according to claim 1, wherein said container contains one of an active filter, a solid-state power factor corrector and a converter.
