Frame for a switchgear cabinet comprising pivotable holders for distribution busbars, and production method for a switchgear cabinet

1. A frame for a switch cabinet, the frame comprising:

a plurality of interconnected frame profiled elements, which define a substantially cuboid outer contour; and

a first retainer and a second retainer,

wherein the retainers are arranged within the substantially cuboid outer contour,

wherein the retainers are vertically spaced apart,

wherein recesses are arranged in the retainers, forming part of an outer contour of an imaginary, generally cylindrical body, an axis of the generally cylindrical body being oriented vertically when the retainers are in an operating position,

wherein the retainers are configured to be moved into an assembly position in which the axis extends obliquely to vertical,

wherein the retainers are connected by rotatably mounted profiled elements, and

wherein longitudinal axes of the rotatably mounted profiled elements are oriented vertically in the operating position and obliquely to the vertical in the assembly position.

2. The frame of claim 1 , further comprising:

a first crossmember, connected to one or more of the retainers or to the rotatably mounted profiled elements,

wherein the first crossmember is arranged on a first cover surface of the imaginary, generally cylindrical body, and

wherein the first crossmember and the first cover surface overlap at least in part.

3. The frame of claim 2 , wherein one or more of the retainers is integrated in the first crossmember.

4. The frame of claim 1 , further comprising:

a second crossmember, arranged on a second cover surface of the imaginary, generally cylindrical body and the second crossmember and the second cover surface overlap at least in part.

5. The frame of claim 2 , wherein the retainers, the rotatably mounted profiled elements, or the first crossmember include bolts and/or bushings that are rotatably mounted in respective bolts and/or bushings of the interconnected frame profiled elements.

6. The frame of claim 2 , wherein, in a state in which screw connections to the interconnected frame profiled elements are loosened, the first crossmember loosely abuts and/or rests against the interconnected frame profiled elements,

wherein degrees of freedom of the first crossmember are limited such that the crossmember can only be significantly rotated relative to the interconnected frame profiled elements about its longitudinal axis, between the operating position and the assembly position.

7. The frame of claim 6 , wherein, in the state, the first crossmember

can be rotated relative to the interconnected frame profiled elements about its longitudinal axis at least by 10°, and/or

can be rotated relative to the interconnected frame profiled elements about a horizontal axis, which normal to the longitudinal axis, by a maximum of 2°, and/or

can be displaced relative to the interconnected frame profiled elements by a maximum of 20 mm.

8. The frame of claim 6 , wherein the first crossmember and/or the interconnected frame profiled elements include first projections which are mounted in first recesses in the interconnected frame profiled elements and/or in the first crossmember, and

wherein the first projections prevent the first crossmember from moving horizontally relative to the interconnected frame profiled elements.

9. The frame of claim 6 , wherein

the first crossmember and/or

the interconnected frame profiled elements and/or

a component arranged on the interconnected frame profiled elements

includes second projections that prevent the first crossmember from rotating about its longitudinal axis relative to the interconnected frame profiled elements.

10. The frame of claim 2 , further comprising:

an electrically insulating bottom plate, arranged on a first cover surface of the imaginary, generally cylindrical body,

wherein the electrically insulating bottom plate and the first cover surface overlap at least in part.

11. The frame of claim 10 , wherein the electrically insulating bottom plate is releasably mounted in a mounting.

12. A switch cabinet, comprising:

the frame of claim 1 ; and

distribution busbars that extend vertically in the operating position,

wherein the distribution busbars are mounted in the retainers and assume the position of the imaginary, generally cylindrical body.

13. The cabinet of claim 12 , further comprising:

main busbars that extend horizontally in the frame,

wherein the main busbars are electrically connected to the distribution busbars.

14. The frame of claim 8 , wherein the first projections prevent the first crossmember from moving horizontally transversely to a longitudinal axis of the interconnected frame profiled elements.

15. The frame of claim 10 , wherein the electrically insulating bottom plate is releasably mounted in the first crossmember, which is connected to the interconnected frame profiled elements,

and/or

wherein the electrically insulating bottom plate is mounted such that it can be released without a tool.
