Abstract

A control box arrangement including at least one control box which is sub-divided, or which can be sub-divided, into a plurality of cuboid compartments, including functional compartments, by wall sections, where vertical wall sections with a horizontal sub-division are provided. A collecting bar arrangement including a distributing bus bar arrangement guides the current, in order to supply electrical energy to appliance components which are arranged in the functional compartments accessible from the front side. An advantageous arrangement of functional compartments and the energy supply of components received therein is achieved by the distribution buses of the distributing bus bar arrangement are guided through a plurality of vertical functional compartments arranged one above the other and separated by horizontal partition bottoms, are mounted inside the compartments, and covered in a protected manner.

Claims

1. A switchgear cabinet arrangement, having at least one switchgear cabinet (2, 3, 4) which with wall sections is dividable into a plurality of cube-shaped partial spaces (5), including functional spaces, to which are provided end vertical wall sections with horizontal divisions, wherein a bus bar arrangement, including a distribution bus bar arrangement (50), conducts electrical current to provide device components arranged in functional spaces accessible from a front, with electrical energy, the switchgear cabinet arrangement comprising:

distribution bus bars (55) of the distribution bus bar arrangement (50) conducted through the functional spaces, which are arranged vertically above each other and are separated from each other by horizontal space divider floors (30) mounted in the interior of the spaces and covered in a touch-proof manner.

2. The switchgear cabinet arrangement in accordance with claim 1, wherein the functional spaces have rear walls embodied as mounting plates (40) which are spaced apart from a rear wall of the respective switchgear cabinet (2, 3, 4) to form a reception space for a main bus bar arrangement (80) of the bus bar arrangement in the rear interior area of the switchgear cabinet, in which main bus bars are mounted which are electrically connected with the distribution bus bars (55).

3. The switchgear cabinet arrangement in accordance with claim 2, wherein the mounting plates (40) of a same height or a different height are provided and have dimensions of a height and a width matched to a second height and a second width of the functional spaces.

4. The switchgear cabinet arrangement in accordance with claim 3, wherein the partial spaces are closed off laterally by lateral wall sections (20) matched to the second height of the functional spaces.

5. The switchgear cabinet arrangement in accordance with claim 4, wherein cutouts (32) are arranged in a rear edge area of the space divider floors (30), through which the distribution bus bars (55) are conducted.

6. The switchgear cabinet arrangement in accordance with claim 5, wherein the cutouts (32) are matched to the extension of the area of the distribution bus bars (55) in a direction of a width and a depth, including the touch-protection covering (51, 51′

).

7. The switchgear cabinet arrangement in accordance with claim 6, wherein the distribution bus bar arrangement (50) is received in a trough-like support (54) having holding strips (54.1) extending along the vertical edges and is fixed in place by horizontally extending bus bar holders (53), and the covers (51), which are applied from the front, and are fixed in place on the holding strips (54.1) by lateral parts (51.1) having snap-in elements.

8. The switchgear cabinet arrangement in accordance with claim 7, wherein a connection between the main bus bars and the distribution bus bars (55) is provided by laminated copper bars and connecting clamps, by bolts, or flexible conductors and connecting clamps, the mounting plates have cutouts for passing the copper bars or flexible conductors through, and the cutouts are closed off by cable bushings or by insulating material.

9. The switchgear cabinet arrangement in accordance with claim 8, wherein for receiving the space divider floors (30), mounting elbows (70) extending laterally in the depth direction are attached to the vertical frame legs (11) and/or the lateral sections and if required to the vertical mounting bars by vertical legs, and the space divider floors (30) are attached to horizontally oppositely oriented legs of two mounting elbows (70) located opposite each other at a same height.

10. The switchgear cabinet arrangement in accordance with claim 9, wherein the horizontal legs of the mounting elbows (70) project inward beyond oppositely directed insides of the front vertical frame legs (11), and a width of the space divider floors (30) at most corresponds to a clear distance between insides of the front vertical frame legs (11).

11. The switchgear cabinet arrangement in accordance with claim 10, wherein the functional spaces have at a front partial doors (16) matched to a height, and/or a front door extends over all functional spaces and is attached.

13. The switchgear cabinet arrangement in accordance with claim 1, wherein the partial spaces are closed off laterally by lateral wall sections (20) matched to a second height of the functional spaces.

14. The switchgear cabinet arrangement in accordance with claim 1, wherein cutouts (32) are arranged in a rear edge area of the space divider floors (30), through which the distribution bus bars (55) are conducted.

15. The switchgear cabinet arrangement in accordance with claim 14, wherein the cutouts (32) are matched to an extension of an area of the distribution bus bars (55) in a direction of a width and a depth, including the touch-protection covering (51, 51′

).

16. The switchgear cabinet arrangement in accordance with claim 1, wherein the distribution bus bar arrangement (50) is received in a trough-like support (54) having holding strips (54.1) extending along the vertical edges and is fixed in place by horizontally extending bus bar holders (53), and the covers (51), which are applied from the front, and are fixed in place on the holding strips (54.1) by lateral parts (51.1) having snap-in elements.

17. The switchgear cabinet arrangement in accordance with claim 2, wherein a connection between the main bus bars and the distribution bus bars (55) is provided by laminated copper bars and connecting clamps, by bolts, or flexible conductors and connecting clamps, the mounting plates have cutouts for passing the copper bars or flexible conductors through, and the cutouts are closed off by cable bushings or by insulating material.

18. The switchgear cabinet arrangement in accordance with claim 1, wherein for receiving the space divider floors (30), mounting elbows (70) extending laterally in a depth direction are attached to the vertical frame legs (11) and/or the lateral sections and if required to the vertical mounting bars by vertical legs, and the space divider floors (30) are attached to horizontally oppositely oriented legs of two mounting elbows (70) located opposite each other at a same height.
