    The invention relates to a frame system for an electrical switchboard, comprising:
    - a plinth system for assembling a plinth part of a selected size from sheet metal structures, vertical structural parts, such as vertical profiles, forming a mounting base for the components, each mounted at its lower end on the plinth part;
    - roof structure support parts mounted on the upper end of the vertical structure parts and the roof structure supported by said vertical structure parts and support parts, and the casing parts of the housing structure.
    The electrical center is the end product after furnishing the electrical center frame structure. Furnishing is the installation of electrical components, cables and control logics in a frame structure. The frame structure must be suitable for the widest possible range of objects. There are a myriad of different electrical switchboards, but some structured system is used to assemble them, which limits the number of frame components.
    The purpose of the electrical switchboard determines how the frame structure is furnished and in which tightness class the shell structure coming on top of the frame is sealed. However, all electrical switchboards built for different needs are different, different in size and equipped with different components according to the need for use.
    Problems to be solved with structure properties:
    Known modular switchboard systems contain a large number of variable parts, which increases the number of items to be manufactured and stored.
    In the known modular switchboard systems, a special spacer and end plates are used separately on both sides for the module division of the plinth.
    20195321 prh 23 -04- 2019
    Countless typical pieces of furniture include a standard DIN rail for mounting components, busbars with brackets, switchboard components, mounting plates and cabling brackets.
    Finnish patent FI 120121B discloses an electrical switchboard frame structure made of sheet metal, which consists of honeycomb-like parts. The most important parts are the modular plinth structure and the central frame panels that can be attached to it, as well as the profiles to which the panel and door cladding are attached. Products are made from sheet metal by cutting, joining and shaping them. Sheet metal is often also called sheet metal.
    The utility model FI8921 presents a solution that improves the division of space with a reversible vertical profile.
    As such, various structures of storage cabinets are known. U.S. Pat. No. 4,421,365 discloses a heavy frame system with support wheels for moving a cabinet on rails. The frame system comprises interconnected transverse and longitudinal beams. These are made of structural steel, especially steel profiles, as both are loaded with point loads. The longitudinal beams (in the depth direction) are profile pipes and have flanges welded to their ends. The strength of the profile tube must be remarkably high to withstand the point load caused by the shafts. The crossbeam must also withstand a considerable 25 point load, as it can be stepped on. Likewise, the lower flanges of the longitudinal and transverse beams are spaced from the base and do not carry a load.
    Although the above modular solutions have come a long way in achieving optimally sized electrical switchboards, the number of parts of the frame system has become large and the division of space is not always optimal and the adjacent block has to be reserved completely due to the small additional space.
    The object of the present invention is to further improve the formability of a power plant system constructed of sheet metal, always optimally, however, by using a minimum number of frame components.
    20195321 PRH 23 -04- 2019
    The objects of the present invention are achieved by the features of claim 1. By means of the invention, the plinth part is assembled with only two different profiles made of sheet metal, namely a front / back plate profile and an end / intermediate profile. It is therefore possible to use only one profile at the front and back. These have different lengths in the standard range, such as 300, 450, 600, 750, 900, 1050 and 1200 mm. The standard dimensions of the end / intermediate profile are, for example, 500, 750 and 1000 mm. It is quite clear that of these 10 different profiles, a myriad of different sized plinths and further electrical centers can be assembled on top of them.
    In the system according to the invention, the front and back plates of the plinth are preferably combined into one part, whereby the number of parts to be varied in this respect is halved. Similarly, the end and intermediate profiles are implemented with one profile in each module size.
    With the help of the two-part structure of the frame profile, the profiles can be moved in the depth direction and rotated around their longitudinal and transverse axes by 180 ° according to the depth adjustment need of the respective depth space.
    Thanks to the modular plinth parts 1 and 2 and the vertical profiles, the electrical center frame can be constructed symmetrically or asymmetrically in the longitudinal direction of the frame, modular in the longitudinal, depth and height direction of the frame and adjustable in the depth direction of the frame structure between spaces.
    The longitudinal and vertical busbars of the electrical switchboard can advantageously be built of the same or different dimensions in any of the spaces to be built in the electrical switchboard frame.
    The plinth can be constructed to be fixed or to dampen vibrations and shocks, and yet for both uses. The stiffness of the plinth and the entire electrical center is achieved by the combined effect of the plinth and the structure above it.
    In the electrical center frame system, the depth of one or more spaces in the depth direction can be adjusted thanks to the vertical profiles and their support system. In one electrical center frame system, the functional vertical profile is formed by two L-profiles together, whereby they can be positioned in both directions against the L-support plate for depth adjustment between different states of the frame.
    20195321 prh 23 -04- 2019
    A modular perforated profile bar (vertical profile) is used to fasten the busbar, electrical panel components, mounting plates and cabling, and to form the vertical structure of the frame. In a central frame structure, one or two halves of the profile can be used to implement depth adjustment of the structure.
    It is essential for profiles to have the following functions that implement their structure and shape. The plinth profiles are preferably made of 2-2.5 mm thick sheet metal. All functions are also related to the thickness of the plate. In practice, however, the thickness of the plate cannot vary within large limits, as it may be impossible to perform various functions on other dimensions.
    1. The end / intermediate and front / rear profile has a support function - they have a sufficient support surface against the base> as a solution the legs of the profile - the legs must have a width against the base, whereby the width of the leg edge is 35 - 45 mm.
    The width of the end / intermediate profile (s = 2 mm) is 35% (30 - 45% of its or plinth height) material thickness 2.5 mm The foot of the front / rear profile (s = 2.5 mm) is 40% (35 - 45%) of the plinth height. The material thickness is 2 mm.
    2. The end / intermediate and front / rear profiles have a mutual function to implement a rigid frame structure> as a solution • stiffening profile shape (35 - 45 mm may be enough for this as well) • front / rear profile has top edge as stiffener in addition to foot edge · end / intermediate profile is open to the side plate thickness 2 mm and 2.5 mm • selected cuts at the ends of the profiles to allow them to be joined together
    20195321 prh 23 -04- 2019 in more detail: the bottom flange of the end / intermediate profile has been shortened according to the width of the second profile
    The front edge of the front / rear profile is lightened (outer edge) to the half-dimension of the second profile, leaving only the bottom5 flange or alternatively formed vertical cavity for the end flange of the first profile.
    3. The end / intermediate and front / rear profiles have a mutual fastening10 function to assemble the plinth> as a solution
    a. End / intermediate profile end plane with set of mounting holes. A width of 35 mm is enough to attach two front / rear profiles to the same end
    b. the front / rear profile has sets of edge holes fitted to the set of end-level mounting holes
    c. alternative set of mounting holes for two mounting points when attaching the full width of the end profile to the front / rear profile
    4. The profiles have support functions for supporting and fastening the vertical profiles> solution: perforated fastening surface at the top and partly at the ends of the end / intermediate profile. Support is provided for end / intermediate profiles. Mainly for a set of holes in the upper flange (35 mm), but there are also mounting holes on the side of the web.
    5. front / rear profile door seal part> solution: the top stiffener (10% bevel) forms the support for the sealing lip. Here, the edging of the sealing lip at the same time stiffens the front / rear profile.
    The invention will now be described by way of the following examples and drawings. The drawings show some examples of electrical switchboards according to the power switch system according to the invention and the components of the system in detail.

    The power plant is always built according to the furniture designed and needed. The frame of the electrical panel in Figure 1 is shown almost complete and is assembled from plinths 1, 2 and various vertical profiles 6, 12, 13, upper profiles 14, roof elements 11.1, 11.2, 11.3 and wall elements 20. Conventional vertical profiles are profiles 12 and 13 placed on corners and on the outer edge. the set vertical profiles 6 with the support plates 4 have the following structural features and special features (Figures 6-8).
    The plinth is assembled from the front / rear profiles 1 and the end / intermediate profiles 2. As shown in Figure 2, the plinth simply consists of two different profiles, namely the front / rear profile 1 and the end / intermediate profile 2. The plinth in Figure 2 has two module dimensions of the front / rear profile. The details of these profiles are presented below, by means of which the front / rear profile 1 can be attached to the end / intermediate profile 2 at two depths, enabling both end25 and extension installations.
    According to Figures 3a to c, the end / intermediate profile 2 comprises, preferably 100 mm high and 2 mm sheet metal edged, in which the laterally open U-shaped profile section consists of a web 2.1, a lower flange 2.2 and an upper flange 2.3. The extension of the web 2.1 is a bevelled end30 into a flange 2.4.
    20195321 prh 23 -04- 2019
    The end flange 2.4 preferably has two sets of mounting holes 2.41, in particular vertical mounting holes and one central mounting hole. The upper flange has a series of mounting holes 2.8 and 2.9 to which mainly the upper frame is attached. The web 2.1 has a series of mounting holes 5 2.7, for example for connecting the ends of transport interruptions.
    It is very essential to have sections 2.5 of the lower flange 2.2, at both ends, which in part allow the profiles 1 and 2 to protrude at an angle of 90 °.
    The front / rear profile of Figures 4a to 4e is preferably made of a 2.5 mm sheet metal, since it is known empirically that the thinner does not withstand the stress caused by the transport rolling. The web 1 of profile 1 forms a visible front and back wall. The foot part comprises a base flange 1.2 and a further flange 1.5. The bottom flange 1.2 receives the point load during transport. At the upper edge of the profile there is a stiffening edge 1.3, 15 which, if necessary, forms a sealing lip against the door, in addition to the fact that the edge edge is necessary to stiffen the profile.
    In addition to the vertical sets of holes at the ends, the profile 1 includes a horizontal set of holes, which will receive the fastenings required by either the base floor plate or the rear sheath.
    Figure 4c shows section A-A for Figures 5a-d.
    Figure 4f shows a variant in which the lower edge 1.5 is extended almost to the end of the profile 11, but the selected location includes a gap 1.8. This makes it easier to assemble the profiles when the web 2.1 of the profile 2 fits in it and is already positioned in the right place when stacking the sock.
    In Figures 5a - d, the web 1.1 of the front rear profile 1 is shown in all parts, i.e. the outwardly visible surface plate is partially cut. In Fig. 1a, the profile 2 is positioned in the front / rear profile specifically as an end profile. According to Fig. 5a, the lower flange 1.2 of the profile 1 fits up to the end due to the section 2.5 30 of the end profile 2 (Fig. 3c). On the other hand, the lower flange of profile 1
    1.2 fits under the web 2.1 of the second profile 2 (Figure 5d). Both lower flanges 1.2 and 2.2 rest on the base, i.e. in the same plane.
    In the other figures 5b - d, the end / intermediate profile 2 acts specifically as a continuator, i.e. two profiles 1 are attached to the end 2.4 of the profile 2.
    20195321 prh 23 -04- 2019 full. According to Fig. 5b, the stiffening edge 1.5 of the front / rear profile 1 extends just against the web 2.1 of the profile 2 (shown on the right). In Fig. 5c, in addition to the partial section of the surface plate, i.e. the web 1.1, the foot part, i.e. the lower flange 1.2 and the stiffening edge 1.5, are cut so that the projection of the profile 2 5 is visible in its entirety.
    In Fig. 5d, in addition to a partial section of the surface plate of the profile 1, the end 2.4 of the profile 2 is cut from its lower part, showing the positioning of the lower flange of the right profile 1 and the stiffener edge 1.5 against the profile 2 web 2.1.
    Figure 6 shows a reduced frame structure with a roof structure supported by vertical profiles on top of the plinth. Figure 8 is a section from A to A. The vertical profiles include the corner profiles 12, the front / rear vertical profiles 12 and the support vertical profiles 6, the structure of which is shown in detail in Figures 7a to 7d. Doors and door divider profiles (not shown) are attached to the vertical profiles 13 and the angle 15 profiles.
    The support vertical profile 6 comprises a double web 6.1, a flange 6.2 and a stiffener edge 6.3 (Fig. 7e). All levels 6.1, 6.2 and 6.3 have sets of holes for support mounting and furniture mounting on the other hand. The support vertical profiles 6 are preferably edged into a shape of 1.5 mm 20 sheet metal. The attachment of the support vertical profile 6 to the L-support plate 4 is well shown in Figure 1. Two opposite L-support plates 4 (s = 1.25 mm) are used in the middle, their vertical webs facing each other and each of their horizontal flanges being attached to the plinth intermediate profile 2. Only one L-support plate 4 is used at the ends , which is attached to the end profile 2 positioned on its outer edge. For this purpose, its flange includes sets of mounting holes arranged for two positions, with which the L-support plate 4 is fastened with screws to the selected position on the upper flange of the end / intermediate profile 2 2.3. The material thickness of the L-support plate is generally 1-2 mm, most preferably 1.1 to 1.5 mm. Vertically, a few intermediate supports are installed between each of the 30 front and corresponding rear support vertical profiles 6 to stiffen the profile structure (not shown).
    This special feature of the support profile is shown in Figure 8 by the transition positions35 ti, where the rear support vertical profiles 6 of the middle plinth part are
    20195321 PRH 23 -04- 2019 mounted slightly inwards in the web of the L-support plate 4, whereby a slightly more depth has been obtained in the middle of the rearmost block than is available in the adjacent blocks. Here, an additional depth of 20 mm is required when using the support insulators 8 required for this additional space for 8 large-capacity busbars. This required additional space can well be taken from the middle block when, for example, the conductor space does not require full modulus depth. In the same way, additional depth can be added to the front block if necessary, if the electrical furniture to be installed so requires. Of course, more depth is obtained even more with this technique, when the attachment of the support vertical profile 10 to the L-support plate 4 can be made to the depth position made possible by the formed series of holes. Often that 20 mm is enough, which saves a lot of space compared to losing the middle block completely.
    For this purpose, the lower and upper intermediate support 4 is adapted to the support vertical profile 6 of the receiving country 15 at different depth positions.
    The invention is suitable as an example for industrial cell center systems which are specially designed as main, ascent and process centers for industrial sites. In one such system, the maximum rated voltage is 690 VAC and the maximum rated current is 5000 A. The maximum oi20 cut-off current values are thermal 100 kA and dynamic 220 kA. The main form of furniture for the devices is fixed, some of the devices can be installed pull-out or pull-out. The structure of such an industrial cell center system is a hot-dip galvanized self-supporting steel plate structure, in which the system body is assembled on top of the plinth structure from 25 self-supporting body parts made of a 1.6 mm thick hot-dip galvanized steel profile. The modular design allows for an almost limitless variety of configurations.
    In another application, the cell-site system is designed specifically for the main and rise centers of real estate sites and the sub-centers of industrial sites. The maximum rated voltage is 690 VAC and the maximum rated current is 3150 A. The maximum short-circuit current values are thermal 60 kA and dynamic 132 kA. In this structure, the frame of the cell center system is assembled on top of the plinth structure from self-supporting frame members 35. The opening angle of the doors is 160 °. This cell center system10 has a hot-dip galvanized self-supporting steel plate structure. The modular design allows for an almost limitless variety of configurations. The field widths of the system are 300, 450, 600 and 750 mm. The frame heights of the system are 1680 and 1960 mm.
