Description

PAOPERMSEW2Oi6U\dI2279490 spe dcO7/071 -1- CONSTRUCTION KIT AND METHOD FOR CREATING AN ELECTRICAL CABINET FOR OUTDOOR USE Field of the invention The invention relates to an electrical cabinet which is generally set up outdoors Sand receives the distribution equipment for low-current systems, for example telephone systems, with associated power supply devices and cable terminating/connecting devices for a specific spatial area.

Background of the invention Electrical cabinets of this type must satisfy various conditions, since they must help to meet the operating conditions, in particular the temperature, of the electrical components, in particular the electronic components, accommodated in them, since they are used in different states/regions, and various technical specifications or standards from the respective operators exist and have to be complied with, or because certain special climatic conditions exist in the intended region and have to be taken into account.

In addition, general requirements, such as adequate structural stability and resistance to vandalism etc., must be satisfied.

Electrical cabinets of this type are, in principle, produced either from metal or from plastic or from both materials, plastic combining the advantage of allowing cheaper production with the advantage of lower weight and an electrically nonconducting material.

In addition, there is the problem that electrical cabinets of this type are not installed on the bare ground, but on or against what are known as base boxes, which are buried entirely or partly in the ground and serve for leading out the buried cables from the underlying ground.

PAOPERkSEWUW)6XhI\I227949O vpC cm07flA)1 S-2- Apart from the different dimensioning of these base boxes and the different heights to which they rise up (upper edge level with the surface of the ground or projecting above it), there are also different requirements with regard to the interaction with base boxes of this type: in one case, the electrical cabinet is intended to rest on the base box, in the other case the base box is not to be Svisible, that is to say the electrical cabinet is intended to encase the base box on the sides and at the top.

0 -This is intended in particular to help to avoid underground engineering work, to the extent that base boxes of an earlier, obsolete type of construction do not have to be exchanged for new bases made to match the electrical boxes.

To avoid a separate electrical cabinet having to be designed and constructed according to prevailing boundary conditions, the object of the invention is to provide such a construction kit and a method for creating electrical cabinets which permits adaptation to the various boundary conditions with only a few individual parts.

The various construction and installation variants which are to be achieved are as follows: Mounting the electrical cabinet on the upper side of a base box ending level with the ground, Receiving a base box rising up from the surface in the lower region of the electrical cabinet, it being received at least in the outer body of the electrical cabinet, better in the interior of the installation frame, Partitioning off the receiving space, that is to say the space within the installation frame, from the intermediate space, that is to say the distance between the installation frame and the outwardly surrounding outer body; in P OPERWSEW\2006u h 12279490 sp dx-077/6 -3this case, a distinction must be made between the partitioning off to the sides and the partitioning off at the top, Arrangement of the predetermined breaking elements between the base box and the electrical cabinet or within the multi-part base box, Fitting out the outer body with or without an upper intermediate part Cbetween the cover and the parts of the body lying thereunder, Fitting out the electrical cabinet with or without EMC shielding.

Furthermore, DE 73 19 283 U proposes to fasten the installation frame of an electrical cabinet in such a way that it can be adjusted in height with respect to the underlying ground. However, this does not take place by fastening at different positions of the installation frame, and nor is it the case that differently dimensioned base boxes and the base boxes rising up to different heights are provided there.

On the other hand, FR 2 785 100 proposes different installation heights of the base on the electrical cabinet, the electrical cabinet not having an installation frame in this case.

DE 296 23 678 U1 also proposes the use of different base boxes, even though, when a plurality of base boxes are used there, altogether the same overall dimensions of the bases, seen in plan view, are always achieved.

In addition, DE 295 19 260 U proposes a double-walled switch cabinet with a distance between the outer skin and the inner skin of the switch cabinet and air circulation taking place in between.

DD 39 240 A proposes an electrical cabinet with an inner installation frame comprising profiles, with venting openings between its outer panelling and its PAOPERMSEVA200SpU\)20Z47632 =mded pgm dm-/I02D6 -4ci

cover.

0 In addition, DE 32 05 934 proposes a bottom panel, which can be made up from a plurality of elements, for an electrical cabinet.

(Ni IIt is therefore desirable to provide a construction kit for creating an electrical C cabinet which can optionally satisfy different specifications with regard to base area and projection of the base above the surface of the ground and also with c regard to EMC shielding and ventilation and venting.

Summary of the invention According to the present invention, there is provided a kit of parts for creating an electrical cabinet for receiving low-current distribution equipment and setting up outdoors, the kit including: an outer body; an inner installation frame; and panelling for the inner installation frame which comprises: a plurality of base boxes dimensioned differently with regard to base area and projection above the ground; mounting plates for connecting the installation frame to individual base boxes; and a plurality of fastening positions on the installation frame for the mounting plates.

The present invention also provides a method for creating an electrical cabinet for receiving low-current distribution equipment and setting up outdoors, the method including the steps of: fastening at least two cross struts to an installation frame at a defined 3o height; arranging mounting plates at fastening positions on the at least two cross struts; P.XOPER\SEW2\2D6,cpUmO0247632 anm ded pagc dom.2J]Ur(X/

after arranging the mounting plates, positioning the installation frame on at O least one of a plurality of base boxes dimensioned differently with regard to their base (Ni area and their projection above the ground; and fastening the mounting plates on the upper side of the at least one base box.

IDTo be able to fasten the electrical cabinet on base boxes rising up to different heights above the surface of the ground, in particular also on base boxes ending level with the N surface of the ground, that is to say not rising up above it, the mounting plates, which establish the connection between the installation frame and the base box, can be 0io arranged at different fastening positions of the installation frame. These fastening positions differ firstly with regard to the height on the installation frame, since they can be arranged either on the lower cross struts of the installation frame. In this case, the electrical cabinet later rests on the upper side of the base box. In the case of a base box ending level with the ground, that is to say more or less on the surface of the is ground the electrical cabinet would extend upward from the upper edge of the base box.

Furthermore, the different base boxes differ in their width, that is to say in the transverse direction, the large base area dimensioning, considered also in depth, the smaller base area dimensioning.

Since specifically the dimensioning of the depth varies greatly, the clear, inner width of the installation frame, within which the base box is to be accommodated, does not have to be dimensioned according to the greatest depth of the base boxes, but instead the installation frame may be designed to be somewhat less deep in comparison, in that one of the lower cross struts of the installation frame is removable, that is to say in the case of very deep base boxes the thickness of the cross strut is also included in order for the base box then still to be accommodated within the outer body of the electrical cabinet but no longer completely within the installation frame. Although the stability of the installation frame is reduced as a result, it stall lies within the acceptable limits, in particular also on account of the fact that, between the upper and lower cross struts, there are, for stiffening purposes, middle cross struts in the transverse direction between the vertical P:\OPER\ 2()JUI\22794A) spc 0o-07/107f6 -6edges and the vertical struts present there of the installation frame. It is preferred, however, for the installation frame, considered in plan view, to run around the base box, that is to say both cross struts are also present.

These cross struts are arranged at a height of the remaining installation frame that corresponds to the height of the upper edge of the base box in the case of base Sboxes rising up above the surface of the ground.

The mounting plates are then fastened to these cross struts by screwing, and, io after the installation frame has been mounted on the base box, these mounting plates, which extend from the front cross strut to the rear cross strut, are fastened on the upper side of the base box.

The spacing of the mounting plates depends on the width of the base box, so that the mounting plates are fastened near the outer ends of the upper side of the base box, in order to achieve a good supporting effect.

If a base box which does not rise up above the surface of the ground, or only slightly, is concerned, or if the electrical cabinet is to rest on the upper side of the base box, these mounting plates are fastened to the lower cross struts.

Furthermore, a distinction has to be made according to whether the receiving space in the interior of the installation frame is to be thermally separated from the surrounding intermediate space between the installation frame and the outer body, that is to say with regard to air circulation and/or with regard to electromagnetic radiation. For a thermal separation, the inner installation frame is panelled with sheet-like, closed panels, preferably on the outer side of the installation frame or on the inner side of the latter. This takes place on the rear side and the side walls.

The front wall, in which the outer body generally has one or more doors for opening the electrical cabinet, must also be fitted out with analogous elements to be opened, that is to say doors or flaps etc., with regard to such panelling on the inner installation frame.

P \OPER\SEW2006\ ul\I2279490 spc dOC-)77A)6 6a Furthermore, a distinction has to be made according to whether or not this inner receiving space is also to be thermally separated at the upper side, that is to say at the upper end of the installation frame, by a closed panel from the cover space lying thereabove of the surrounding body. In this case, panelling of the upper side of the inner installation frame is also necessary. This may take place by means of a separate panelling part or else by mounting an intermediate part between the cover of the outer body and the rest of the body, provided that this intermediate part has a continuous lower panel and, in spite of the fastening to the remaining io parts of the outer body, can be mounted snugly on the upper side of the inner installation frame.

This must be ensured by the connecting elements used for the purpose of fastening the outer body to the inner installation frame allowing this intermediate part to be mounted on the upper side of the installation frame.

The outer body generally comprises panel-shaped individual parts for the individual walls and additionally, on the front side, one or more doors which can be moved with respect to the front panel, and also a separate upper cover.

The outer body, in particular its panel-shaped individual parts, generally consist of plastic, in particular, to improve the insulation, of foamed plastic, in particular foamed polycarbonate.

In addition, the construction kit may also comprise an outer body and, in particular, panel-shaped individual parts of such an outer body made of metal, in particular sheet steel or sheet aluminum.

In this case, the outer body has inlet openings in the lower region for letting the ambient air into the intermediate space. Outflow openings are present between the cover and the rest of the outer body or in the upper intermediate part, it being necessary for flowing of the air rising up in the intermediate space on account of heating up caused by solar radiation on the outer side of the parts of the body from the intermediate space into the upper intermediate part to be made possible by lead-through openings.

The lower inlet openings may also be realized by a distance which serves for allowing the air to enter the intermediate space existing between the lower end of the walls of the outer body and the ground.

Consequently, a number of thermal circulation models can be realized: if the inner receiving space is separated laterally and at the top from the surrounding intermediate space, an air circulation taking place exclusively in this inner installation space is established initiated by the waste heat of the active electrical P OEEO6U 1299 spc d 0V -8elements arranged in the inner receiving space, such as lost heat of the control electronics etc. Heat is extracted from this circulation, in that the circulation heats up the panelling of the installation frame, and this panelling is cooled in that, on the outside, in the intermediate space between the panelling of the installation frame and N 5 the outer body, air from the ambience flows in at the bottom and flows out again at the IN top, possibly via the upper intermediate part and possibly by means of active cooling by the intermediate part (a fan which accelerates the circulation between the outer Sbody and the inner, panelled installation frame partitioned off from the intermediate 0 space with respect to the outer body, or a heat exchanger or cooling element in the panelling of the inner installation frame, in particular the upper termination of the latter, although the partitioning off between the inner installation space and the outer intermediate space between the panelled installation frame and the body is to be retained).

If the inner receiving space is only partitioned off at the sides from the intermediate space by means of panelling, this inner circulation also includes the cover space, that is to say the space between the cover of the outer body and the remaining parts of the body. In general, however, the installation frame is also panelled at the top and is consequently partitioned off both at the top and at the sides, and consequently completely, from the outer intermediate space, that is to say the space between the panelling of the installation frame and the surrounding body.

The procedure during the installation of the electrical cabinet on the base box may also vary.

If the electrical cabinet is not intended to enclose the base box, but merely to rise up from the upper side of the latter, simple mounting firstly of the installation frame is self-evident, it generally being the case that the outer body and/or the interior fitting out of the installation frame, including the subrack, only takes place subsequently.

If, on the other hand, the electrical cabinet is intended to enclose the base box projecting above the surface of the ground, different procedures are possible.

If the buried cables, which can only be bent with difficulty, protrude out above the P \OPER\SEWM u61XVuI\12279490 spc do-)7A)7A( -9upper side of the base box, it is preferred for the electrical cabinet, that is to say firstly Sits installation frame, to be slipped over the base box from above.

If, however which is not generally the case the base box is larger in terms of base c 5 area than the clear interior space of the installation frame, this is not possible.

Cc It is then appropriate for the installation frame to be pushed horizontally over the (-i N- upwardly projecting part of the base box, it being necessary for this purpose for one of 0the lower cross struts of the installation frame first to be detached from the latter and (-i 0io also to remain removed if the base area of the base box is greater than the clear interior space between the fitted lower cross struts of the installation frame.

If an existing base box, projecting above the surface of the ground, still does not comprise predetermined breaking elements between the part of the base box projecting out of the ground and the part located in the ground, such predetermined breaking elements must be provided when the electrical cabinet is fastened to the base box, for example between the mounting plates and the base box.

Brief description of the drawings Embodiments according to the invention are described in more detail below by way of example and with reference to the figures, in which: figure 1 shows basic representations of the installation versions in section, figure 2 shows thermal circulations in the electrical cabinet in section, figures 3 show individual views of the installation state without an outer body, figures 4 show individual views according to figures 3 with an outer body, figure 5 shows a perspective view of the state of figure 3, figure 6 shows the perspective view in a further advanced installation state, P kOPEMSEWUM6 kI\I 2279490 9 dx)7Kl7A figure 7 shows a perspective view of the partly installed switch cabinet on a Sbase according to figure 1 b and figure 8 shows a perspective view of the switch cabinet according to figure 7 Safter complete installation C- Detailed description 0io Figures 1 and 2 show electrical cabinets 1, considered with a viewing direction into the depth 40 of these electrical cabinets, in each case cut open along the transverse direction 20, the direction of greatest horizontal extent of these electrical cabinets.

Figure la shows the installation diagram of a base box 2a with a superstructure. This base box 2a rises up partly upward above the surface of the ground 22. The projecting part 2a' is usually connected by means of predetermined breaking elements 21 with respect to the part 2a" embedded in the ground, in order that the tearing off of the upper part 2a' when it is driven into by a car does not also damage or displace the part 2a" lying in the ground.

The base box 2a is usually open at the top and bottom and serves for leading out the buried cables 8, which are laid underground, with their free end upward in the direction of the electrical cabinet to be provided there, and also as a stable foundation for the electrical cabinet to be provided on it.

Furthermore, additional elements, for example batteries 16, which are intended to ensure a power supply to the control components of the electrical cabinet over a PAOPER\SE\UVQ(X uI\Iu 2279490 spc coc07/07A96 -11certain time even in the event of a power failure, may be accommodated in the interior Sof the base box, in particular within its upper part 2a'.

The electrical cabinet 1 in this case encloses the upper part 2a of the base box 2a, protecting upward above the surface of the ground 22. The inner installation frame 6 IDof the electrical cabinet 1 is generally made up of individual struts, which run along the outer edges of the cubic form of this installation frame 6 and usually comprise metal C profiled struts, for instance made of aluminum. The interior space of this installation frame 6 serves for receiving subassemblies such as fuses and controllers in at least l0 part of this receiving space. In the case of base boxes 2a projecting above the surface of the ground 22, the upper part 2a' of the base box 2a is received in the lower receiving space 42 of the installation frame 6, which is partitioned off for this purpose, for example by means of cross struts 34a,b running in the transverse direction, from the upper receiving space 41, which serves for receiving the subassemblies of the electrical cabinet.

As figure la shows, the installation frame 6 with its middle cross struts 34a,b, running between the upper and lower ends, and the mounting plates 45 running therein in the direction of the depth 40, are mounted on the upper side of the upper part 2a' of the base box 2a, so that the vertical corner struts of the installation frame extend alongside the upper part 2a' of the base box 2a further downward to just above the surface of the ground. The mounting plates 45 are fastened to the cross struts 34, set back inward from the free ends of the latter to such an extent that they still lie in the region of the transverse extent of the base box 2a.

In the region of the height of the upper receiving space 41, subracks 9 in the form of vertically running struts are screwed between the upper cross struts 35c,d and the middle cross struts 34a,b on which subracks there can be arranged carrier plates 11, which carry the individual electronic or electromechanical subassemblies. Slipped over this installation frame 6 possibly panelled as described later is the outer body 3, which represents the outer protection, in particular weather protection, of the electrical cabinet and also serves for its climatic control, as described below. The outer body 3 often consists of plastic and is in this case as figures 4 and 6 show in particular made up of individual panels for the rear wall, side walls, doors and cover.

At the height of the middle cross struts 34, the upper receiving space 41 may be additionally separated from the lower receiving space 42 by a bottom sheet 18, which however must have the appropriate clearances for the buried cables 8.

The installation diagram of figure lb is based in comparison on a base box 2b which on the one hand ends with its upper side at the height of the surface of the ground 22, that is to say it is completely within the ground, and has in addition a different, generally larger, base area extent, at least in the transverse direction In this case, the electrical cabinet 1 is fastened with its lowermost horizontal struts on the upper side of the base box 2b sunken completely in the ground, the mounting plates 45 in turn being fastened in the direction of the depth 40 between the front and rear, lower cross struts 35a,b, to be precise set outward in the transverse direction 20 to such an extent that they rest on the ends of the upper side of the base box 2b.

In the middle region, the installation frame 6 is in this case preferably stiffened as before by means of middle cross struts 34a,b, but now the receiving space 42 located below these middle cross struts can optionally likewise be used for receiving electrical subassemblies, including for receiving batteries 16. In this lower receiving space there may also be an element fastened horizontally to the installation frame 6, for fixing the position of the buried cables, for example a cable fastening rail 28.

The arrangement of the remaining elements in relation to the surface of the ground 22 is the same as in the case of figure 1 a. What is different is the arrangement of the predetermined breaking elements 21, which are now arranged between the mounting plates 45 and the base box 2b.

I

P X0PERSE\VQ(X)6%J 22Z794, $PC dox4)7M7A) -13- Figure 2 shows the form of installation according to figure 1 b in the same sectional representation but with regard to the air circulation now taking place within the C electrical cabinet 1, caused by uneven heating up.

On the one hand, the outer body 3 is in this case exposed to solar radiation. On INDthe other hand, arranged at least in the upper receiving space 41 are electrical Ssubassemblies 12, which are energy consumers and produce waste heat, and consequently heat up the receiving space 41.

0io If the upper receiving space 41 is open with respect to the lower receiving space 42, that is to say in between there are only the cross struts 34a,b on the sides, a vertical circulation in which the heated air rises, cools on the upper frame cover 26 and falls downward, is produced in the interior of the installation frame 6, extending over both receiving spaces 41, 42.

Separately from this there exists an air flow in the surrounding intermediate space 19 between the installation frame 6 and the outer body 3, if the installation frame 6 is panelled for this purpose on the outside with plastic panels or other continuous panels. If this panelling is additionally intended to offer EMC shielding, a metallic covering, or at least fitting out with metal foil, is necessary for this.

For the interior space of the installation frame 6 to be accessible, the panelling of this installation frame 6 must likewise have inner doors or flaps.

The air flow in the intermediate space 19 is not a closed circulation, but instead the air penetrates here through inlet openings 27 in the lower region of the body 3 into the intermediate space 19, for example as represented on the right-hand side of figure 2 in that the outer walls of the body 3 do not quite reach down to the ground.

In the upper region of the body, there are air outlet openings 13, either between the cover 5 and the side walls of the body 3 or in an upper intermediate part 7, which is set between the cover 5 and the rest of the body 3, and may have additional active or passive cooling or heating components.

Figures 3 show the installation situation of figure 1 a, that is to say with the base box 2a rising up partly above the surface of the ground 22, with not yet completed fastening of the installation frame 6 to the base box 2a, in rear view (figure 3a), side view (figure 3b), front view (figure 3c) and plan view (figure 3d).

As figures 3a-c show in particular, middle cross struts 34a,b are in this case fitted between the vertical struts of the installation frame 6, such that they run in the transverse direction 20. Fastened to the installation frame, in particular to these cross struts 34a,b, are mounting plates 45, which run from the front cross strut 34a to the rear cross strut 34b, that is to say in the direction of the depth 40 of the electrical cabinet 1. The height of the cross struts 34a,b is chosen such that, when the mounting plates 45 are mounted on the upper side of the upper part 2a' of the base box 2a, the installation frame 6 ends just above the surface of the ground 22.

To achieve this positioning, one of the lower cross struts according to figures 3 and also the analogous, three-dimensional representation of figure 5, for example the front lower cross strut 35a, is removed from the installation frame 6 and the installation frame 6 is then pushed horizontally along the ground or, raised just slightly, over the upper part 2a' of the base box 2a in such a way that, as described, the mounting plates 45 rest on the upper side of the base box 2a.

While this pushing-over has only partly taken place in figures 3 and 5, figure 6 shows a later installation state, in which the pushing-over has been completed and the previously removed lower cross strut 35a has also been fastened again to the installation frame 6, and side walls and the rear wall of the body 3 and also the cover 5 have already been mounted on the outer side of the installation frame 6, at a distance, with an upper intermediate part 7 being arranged between the cover and the remaining body 3, permitting air outlet openings 13 for the air to leave from the intermediate space 19 between the outer body 3 and the inner installation frame 6.

The representations of figures 4, the individual views of which correspond with regard to the viewing direction to those of figures 3, show yet a further installation state in comparison with the latter, in which the outer body 3 has also already been completed by adding a door 4 and a front panel 14.

Figure 7 shows the partly completed electrical cabinet 1, mounted on a base box 2b. The main difference in comparison with the representations of figures 5 and 6 is that, in the case of figure 7, the electrical cabinet 1 is mounted with its lower edge on the upper side of a base box 2b, and consequently overall in accordance with the basic representation of figure 1 b, since this base box 2b is fitted essentially completely in the ground, so that the upper edge of the base box 2b is at the same time the surface of the ground 22. As can be seen, the base box 2b comprises a grid as a base, on which the base structure rises up, and has an outer surrounding of its own in the upper region, near the surface of the ground 22.

On the open upper side of this base box 2b there is fastened, according to figure 7, the installation frame 6 of the electrical cabinet 1, in which as a difference from figures 5 and 6 the mounting plates 45, which in the side regions extend through from the front cross strut to the rear cross strut, are not fastened to the cross struts 34a,b, fastened in the middle region of the installation frame 6, but to the lower cross struts This produces a height of the installation frame 6, and consequently also of the later electrical cabinet 1, above the surface of the ground 22 which corresponds to the other solution according to figures 5 and 6, but, according to figure 7, the lower receiving space 42 is also available for receiving electrical components.

It is nevertheless also the case with the solution according to figure 7 that the subracks 9 extend only from the middle cross struts 34 to the upper cross struts.

In figure 7, the upper sides and the side faces and also the rear side are provided with a paneling 46 of continuous panels, preferably made of an EMC-shielding P \OPER\SEVA2(X)6\Ju\12279490) spc dc4)7/7A)6 O-16material such as aluminum for instance, which are fastened between the struts of the installation frame 6.

Figure 8 shows the structure of the electrical cabinet at a more advanced stage of M 5 completion in comparison with figure 7, that is to say with a complete body 3, surrounding the installation frame 6, including an upper intermediate part 7 mounted N' thereupon, with already described air outlet openings 13 at the periphery and a cover closing off the upper intermediate part 13 at the top.

(Ni io The front side of the electrical cabinet is in this case closed over the height of the upper receiving space 41, that is to say from the front middle cross strut 34a to the front upper cross strut, by a door 4 hinged on the right, while the lower front region, that is to say the height of the lower receiving space 42, is closed by means of a front panel 14, which may preferably be swung open forward by means of hinges in the lower region, along the lower edge.

If an EMC shielding of the electrical cabinet 1 is desired, the front panel 14 and door 4 must likewise provide EMC shielding and, if produced from plastic, preferably have an inner covering of EMC-shielding material, such as aluminum for instance.
