Abstract

An exemplary power-electronic switching system has a plurality of switching units, wherein each switching unit includes a housing and at least one switching module which is arranged within the housing. A mounting unit has a holding apparatus, on which the housings of the switching units are arranged. The holding apparatus includes an insulation material for electrically insulating the holding apparatus from the housings of the switching units and the housings of the switching units from one another. The insulation material allows the housings of the switching units of the switching system to have different voltage potentials from one another and additionally can be realized in a simple and space-saving manner and easily be assembled. In addition, the housing of each switching unit includes a material for at least partially shielding an electric and magnetic field.

First claim

What is claimed is:

1. A power-electronic switching system comprising:
a plurality of switching units, each switching unit including:
a housing;
at least one switching module which is arranged within the housing; and
a mounting unit, wherein the mounting unit has a holding apparatus, on which the housings of the switching units are arranged,
wherein the holding apparatus includes an insulation material for electrically insulating the holding apparatus from the housings of the switching units and the housings of the switching units from one another, and
the housing of each switching unit includes a material for at least partially shielding an electric and magnetic field,
wherein the holding apparatus includes two limbs for fixing the respective housing of the switching unit to the holding apparatus, and
wherein the switching units are arranged next to one another along the two limbs, wherein adjacent switching units are separated from one another and connected to one another by means of at least one spacer element.

2. The power-electronic switching system as claimed in claim 1 , wherein the housing of each switching unit has a substantially cube shape, wherein the corners and edges of the housing are rounded.

3. The power-electronic switching system as claimed in claim 2 , wherein holding means are provided within the housing of each switching unit for holding the at least one switching module.

4. The power-electronic switching system as claimed in claim 1 , wherein the housing of each switching unit is of multipartite design.

5. The power-electronic switching system as claimed in claim 1 , wherein holding means are provided within the housing of each switching unit for holding the at least one switching module.

6. The power-electronic switching system as claimed in claim 5 , wherein the holding means are rails or rail-like.

7. The power-electronic switching system as claimed in claim 1 , wherein the limbs are arranged substantially parallel to one another.

8. The power-electronic switching system as claimed in claim 1 , wherein the spacer element includes an insulation material for electrically insulating the switching units which are connected to the spacer element.

9. The power-electronic switching system as claimed in claim 8 , wherein the mounting unit is an integral design.

10. The power-electronic switching system as claimed in claim 1 , wherein the housing of each switching unit has a plurality of openings.

11. The power-electronic switching system as claimed in claim 1 , wherein an electrical energy store is provided for each switching unit, said electrical energy store being connected to the at least one switching module of the associated switching unit.

12. The power-electronic switching system as claimed in claim 11 , wherein the electrical energy store is arranged within the housing of the associated switching unit.

13. The power-electronic switching system as claimed in claim 12 , wherein holding means are provided within the housing of each switching unit for holding the at least one switching module,
wherein the holding means are rails or rail-like, and
wherein the limbs are arranged substantially parallel to one another.

14. The power-electronic switching system as claimed in claim 13 , wherein the housing of each switching unit has a substantially cube shape, wherein the corners and edges of the housing are rounded, and
wherein the spacer element includes an insulation material for electrically insulating the switching units which are connected to the spacer element.

15. A power-electronic switching system comprising:
a plurality of switching units, each switching unit including:
a housing;
at least one switching module which is arranged within the housing; and
a mounting unit, wherein the mounting unit has a holding apparatus, on which the housings of the switching units are arranged,
wherein the holding apparatus includes an insulation material for electrically insulating the holding apparatus from the housings of the switching units and the housings of the switching units from one another, and
the housing of each switching unit includes a material for at least partially shielding an electric and magnetic field,
wherein an electrical energy store is provided for each switching unit, said electrical energy store being connected to the at least one switching module of the associated switching unit.

16. The power-electronic switching system as claimed in claim 15 , wherein the electrical energy store is arranged within the housing of the associated switching unit.

17. The power-electronic switching system as claimed in claim 15 , wherein the holding apparatus includes two limbs for fixing the respective housing of the switching unit to the holding apparatus.

18. A power-electronic switching system comprising:
a plurality of switching units, each switching unit including:
a housing;
at least one switching module which is arranged within the housing; and
a mounting unit, wherein the mounting unit has a holding apparatus, on which the housings of the switching units are arranged,
wherein the holding apparatus includes an insulation material for electrically insulating the holding apparatus from the housings of the switching units and the housings of the switching units from one another, and
the housing of each switching unit includes a material for at least partially shielding an electric and magnetic field,
wherein the housing of each switching unit has a substantially cube shape, wherein the corners and edges of the housing are rounded,
wherein the holding apparatus includes two limbs for fixing the respective housing of the switching unit to the holding apparatus,
wherein the limbs are arranged substantially parallel to one another, and
wherein the switching units are arranged next to one another along the two limbs, wherein adjacent switching units are separated from one another and connected to one another by means of at least one spacer element.

19. The power-electronic switching system as claimed in claim 18 , wherein the spacer element includes an insulation material for electrically insulating the switching units which are connected to the spacer element.

20. The power-electronic switching system as claimed in claim 19 , wherein the mounting unit is an integral design.
