Description

[0001] The invention relates to a distribution and / or transformer station with a housing and with energy-technical devices arranged inside the housing, wherein the housing has a foundation made of concrete and side and / or longitudinal wall parts arranged upright from the foundation and a roof part supported on the wall parts.

[0002] The invention relates in particular to medium-voltage switchgear with and without transformers (switchgear cells), which serve as interfaces between the medium-voltage and low-voltage levels in the power supply system. Due to the massive expansion of renewable energies (photovoltaics, wind turbines, and e-mobility), the demand for new such stations in the form of local grid stations, transfer stations, and load distributors for energy distribution in the supply grid is increasing.

[0003] Currently, concrete is the primary construction material used in the manufacture of accessible and non-accessible stations and load distributors. The station buildings currently available on the market consist of a reinforced concrete room cell that is arc-proof and tested according to DIN VDE 0671-202. The concrete building body is constructed monolithically, i.e., from a single cast of reinforced concrete. DIN 1045 specifies a minimum thickness of 10 cm for the load-bearing walls made of reinforced concrete. The roof of the station body is also constructed as a single piece from waterproof concrete (cassette roof) and is mounted on the station body in a sliding manner. The edge of the roof has a concrete parapet all around. The roof is drained via a downpipe with a free outlet.

[0004] As has been shown, the environmental impact of concrete is very poor. In fact, the production and use of concrete is responsible for 4-8% of global CO2 emissions. This is partly due to the binding agent cement. Cement is conventionally fired at a temperature of around 1,450°C, requiring very high energy expenditure. The firing process and the resulting deacidification of the limestone release a large amount of CO2. If concrete stations are to be kept as small as possible to limit material consumption, the insulating gas sulfur hexafluoride (SF6) must be used in the switchgear, without which a compact design is impossible. However, the good electrical insulating properties of SF6 are used at the expense of the environment. For example, 1 kg of SF6 has the same climate-damaging effect as 24 t of CO2.

[0005] The object of the invention is to create an alternative to conventional concrete stations that can be manufactured in a more climate-friendly, cost-effective, and / or labor-efficient manner—preferably while maintaining the station's size. The invention should also preferably facilitate transport and, at the end of the station's life cycle, enable environmentally friendly disposal or recycling.

[0006] This object is achieved with the invention in that the side and / or longitudinal wall parts and / or the roof part are designed as particularly solid wooden construction elements and are connected to one another and to the foundation by means of wall and floor connection devices.

[0007] The solution according to the invention creates an optimized design of a particularly walk-in transfer station, which consists to a considerable extent of renewable and alternative materials that meet current testing and network requirements. The focus of the development is the design and testing of a functional transfer station, the side and longitudinal wall sections and preferably also the roof section of which are made of the alternative material wood, which not only significantly reduces the costs for transport and assembly and dismantling, but also results in a much more environmentally friendly product than a switchgear station made entirely of concrete. The body of the new station according to the invention, due to its new design, has significant advantages over known stations. Firstly, the wooden structure (480 kg / m 3) has a significantly lower weight than a station building made of pure reinforced concrete (2,500 kg / m 3). Overall, the lighter wooden structure allows for a weight saving of approximately 70% compared to the construction weight of a reinforced concrete structure. Furthermore, the wooden structure offers great flexibility, as the dimensions of the stations are neither tied to prefabricated formwork units nor to fixed production sites. Each station unit can be individually adapted to customer and network-specific requirements. For station buildings made of reinforced concrete, there are fixed production sites with partially prefabricated formwork units in various sizes, the adaptation of which is considerably more complex. Another important aspect is the availability of the station units. Delivery times for the familiar, monolithic reinforced concrete station units are currently at least 60 weeks, after full coordination with the customer.A station designed according to the invention, on the other hand, can be delivered in a much shorter time, for example after just 10 to 20 weeks.

[0008] Finally, a station according to the invention can also be disposed of or recycled in a more environmentally friendly way at the end of its life cycle. While the disposal of reinforced concrete requires a concrete crushing plant in which the reinforcement (steel) is separated from the concrete, which is associated with high costs, the wooden components used according to the invention can be easily dismantled on site, recycled, burned, or even reused for other construction projects. In addition, the use of wood binds CO2, as the trees used to manufacture the panels absorb and bind CO2 during their growth phase. This CO2 would only be released again through combustion.

[0009] In an advantageous embodiment of the invention, the wall sections and / or the roof section have a multi-layer structure, with at least one front side, a back side, and at least one intermediate layer arranged therebetween, which are preferably connected to one another over a large area and are further preferably each made of wood or a wood composite material. In particular, the wall sections and / or the roof section can be made at least partially of cross-laminated timber with at least three plywood layers.

[0010] Since the foundation, when the station is assembled, either rests on the ground or - in most cases - is embedded in it, it is made of concrete, as with the "standard stations" used to date. Preferably, the foundation can form a basement space provided with cable ducts and / or designed to accommodate at least one of the energy-related devices. The design can advantageously be such that the foundation is constructed as a reinforced concrete basement foundation with a floor-side foundation slab and basement base walls rising from the foundation slab, with the side and / or longitudinal wall sections, which according to the invention are designed as timber construction elements, being connected to the basement base walls at the top side. In contrast to the standardized, known concrete stations, the foundation in the invention is preferably not cast monolithically, but rather is constructed as a multi-part structure.This can preferably be achieved by constructing the basement base walls as separate concrete components and connecting them to the foundation slab in a watertight and oiltight manner. A seal, preferably a joint sealing tape, can be arranged between the foundation slab and the basement base walls.

[0011] The wall and floor connection devices used to connect the wall sections, preferably made of cross-laminated timber, and anchor them to the foundation or its basement walls can include tie rods, wind trusses, and / or dowels. The construction can be designed so that the connections are not visible after assembly. The roof, also preferably made of cross-laminated timber, is connected to the side and / or longitudinal wall sections with suitable connectors.

[0012] Preferably, the wall sections and / or roof section are provided with weather protection on their exterior. This can, for example, be a paint finish and / or a weatherproof cladding or coating.

[0013] The roof section that is particularly exposed to weather influences can preferably be covered on its outer surface with a bitumen protective layer, such as tar paper or a waterproof roofing membrane, or similar. Alternatively, the roof can also be covered with galvanized sheet metal or similar for waterproofing. Furthermore, it is advantageous if the roof section has at least one eaves edge covered with a zinc sheet profile.

[0014] At least one of the wall sections of the station according to the invention is preferably provided with a door opening, thus ensuring accessibility to the station according to the invention. Similarly, at least one of the wall sections can also be provided with a window opening.

[0015] It has proven particularly advantageous if at least one intermediate partition wall is provided in the interior space delimited by the wall sections, which partition wall divides the interior space into at least two sub-spaces. The entire interior space of the station can thus be structured or subdivided according to the respective importance or purpose of the energy-related equipment accommodated therein. In addition, in a particularly advantageous design, the intermediate partition wall can fulfil the function of a protective wall, which can protect people who are in the station, for example for adjustment or maintenance work, from the consequences of a fault, e.g. a short circuit. In this context, it is advantageous if a free space extending over at least part of the length of the partition wall is formed between an upper end of the intermediate partition wall and the roof section, or if the intermediate partition wall is provided with a gas-permeable window opening in its upper region.A high increase in pressure and temperature occurring during a short circuit in a power installation causes a pressure wave inside the housing, which can be kept away from people in the station by means of the intermediate partition.

[0016] To structure the interior of the station, a walkable floor can preferably be provided above the foundation slab, preferably at least approximately at the level of the top of the basement plinth walls. For this purpose, a supporting beam construction with several supporting beams for the floor can be connected to the basement plinth walls. The actual walkable floor can then consist of floor boards or panels, preferably also made of wood, for example OSB boards or rough-sawn boards, which are laid on and attached to the supporting beams. Laminated plywood boards, also known as "screen-printed boards," have proven particularly sustainable for the floor. These boards are roughened on their top side and are therefore reliably slip-resistant. These boards, generally made of birch wood, can be easily disposed of in an environmentally friendly manner, similar to the wooden wall sections and the roof section.

[0017] It has proven particularly advantageous if one of the sub-spaces forms a pressure guide shaft delimited by at least one intermediate partition wall, a longitudinal wall section and / or a side wall section, which is connected via a pressure equalisation opening in the floor to the basement space formed below the floor and delimited by the foundation. Below an energy-related device at or in which a fault such as a short circuit can occur, the floor is preferably interrupted so that there is a direct connection to the basement space below this device. In the event of a short circuit, the pressure wave triggered by this can initially spread into the basement space and from there through the pressure equalisation opening into the pressure guide shaft, from which it only exits again at the top and thus above a person inside the building and is distributed within the volume of the station.the pressure is equalized through a window or door opening.

[0018] The floor is conveniently provided with a lockable inspection opening for access to the cellar space located below the floor.

[0019] The roof section can be designed in the manner of a pent roof, with the side wall sections preferably having a sloping upper edge corresponding to the desired roof pitch, so that the roof section rests essentially completely on all wall sections. The longitudinal wall sections then preferably have different heights corresponding to the desired roof pitch.

[0020] The energy-technical devices for which the station according to the invention is intended to accommodate comprise - as is usual with transformer substations or switchgear cells of the type discussed here - at least one switchgear, a measuring panel, a telecontrol cabinet, a transformer and / or a meter cabinet.

[0021] In a facility with a transformer, the transformer is preferably arranged separately in one of the compartments, while the remaining power equipment is arranged in at least one other compartment. At least some of the power equipment is preferably arranged on at least one of the longitudinal or side wall sections and, in particular, is fixedly connected to it. Mounting the facility(ies) on a side or longitudinal wall section consisting essentially of wood is particularly easy.

[0022] As already indicated, the switchgear and / or the measuring panel can be connected to the energy-related equipment arranged in the basement area, in particular to electrical supply and discharge lines, via access openings or recesses in the floor, preferably formed below them.

[0023] The at least two sub-chambers are preferably each equipped with separate, spaced-apart access openings. It is also advantageous if the housing is provided with at least one ventilation opening and / or a window arranged in one of the side and / or longitudinal wall sections. The arrangement can preferably be such that the ventilation opening and / or the window is closed or closable by means of a weather protection grille or the like.

[0024] Further features and advantages of the invention will become apparent from the following description and the drawing, in which two preferred embodiments of the invention are explained in more detail by way of example. It shows: Fig. 1 shows a first embodiment of a transfer station according to the invention in a perspective external view; Fig. 2 the station after Fig. 1 in a partially cutaway view to illustrate its interior; Fig. 3 the station after Fig. 1 and Fig. 2 in horizontal section; Fig. 4 the station after the Fig. 1 to 3 in a vertical longitudinal section; Fig. 5 a second embodiment of the invention in a Fig. 2 corresponding representation; Fig. 6 the station after Fig. 5 in a vertical longitudinal section; and Fig. 7 the subject of Fig. 5 and Fig. 6 in a vertical cross section.

[0025] At the Fig. The distribution or transfer station shown in Figures 1 to 4, collectively designated 10, is a medium- or low-voltage switchgear which can be used as a switchgear cell for the medium- or low-voltage supply of municipalities or companies.

[0026] The station 10 has a housing 11, inside which several energy-related devices are arranged. Fig. In the embodiment of a transfer station shown in Figures 1 to 4, a switchgear 12, a measuring panel 13, a telecontrol cabinet 14 and a meter cabinet 15 are provided as energy-technical equipment.

[0027] The housing 11 has a foundation 16 constructed as a basement foundation made of reinforced concrete. For this purpose, the basement foundation 16 has a bottom-side foundation slab 17 and basement base walls 18 projecting from the foundation slab, which are made of reinforced concrete as separate components from the foundation slab 17 and are connected to it in a watertight and oil-tight manner. To ensure tightness, a joint sealing strip 19 is arranged between the foundation slab 17 and the basement base walls 18 erected on it in its edge area. The base walls 18 are firmly connected to the foundation slab by means of tension anchors or steel angles and dowels (not shown). The foundation, with its lower foundation slab 17 and the basement base walls 18 projecting from it, forms a basement space 20 provided with cable ducts 21 located in the two longer of the basement base walls 18.

[0028] Two side wall sections 23 and two longitudinal wall sections 24 of the housing 11, constructed as solid timber structural elements, are mounted on the foundation 16 or its basement base walls 18 on their upper sides 22. The wall sections 23, 24 each have a multi-layer structure, consisting of SBS-100-3 cross-laminated timber with at least three plywood layers each, the front and back of which are made of spruce or fir, or a wood of comparable or better quality. In particular, the outer visible layer exposed to the weather can be made of Douglas fir or larch.

[0029] The wall sections 23, 24 are connected to each other by means of concealed T-fittings 25, whose crosspieces are secured to the side wall sections 23 in the outer joint area 26 with the longitudinal wall sections 24 in a suitable manner, for example by means of screws or nails. The legs of the fittings 25 protruding from the crosspieces engage in slots milled into the end faces 27 of the longitudinal wall sections 24. The legs of the fittings 25 are screwed to the longitudinal wall sections 24 using suitable screws, preferably from the inside.

[0030] The wall parts 23, 24 standing on the upper sides 22 of the cellar base walls 18 are fastened by means of wind trusses 28, which are screwed on the inside to the cellar base walls 18 and the wall parts 23, 24.

[0031] The housing 11 is closed at the top with a roof section 29, which also consists of a plywood panel supported on the upper sides of the wall sections 23, 24. The connection between the roof section 29 and the wall sections 23, 24 is also made here by means of T-fittings, the crossbars of which are screwed to the underside of the roof section and whose downwardly projecting legs engage in grooves formed on the upper side of the wall sections. In the exemplary embodiment, the roof section 29 is designed as a flat roof, which is provided with a circumferential eaves edge 30 made of zinc sheeting. The upper side of the roof section exposed to the weather is covered with a waterproof roofing membrane 31 and thus made weatherproof. Alternatively, other measures can of course be taken to seal the roof, for example a seal made of tar paper, a galvanized roof sheet, or the like.

[0032] The front side wall section 23V is provided with a door opening 32 to allow access to the enclosure. Upon entering the enclosure, one reaches a floor 33, which is arranged at the level of the top surface 22 of the basement base walls 18. For the floor 33, a supporting beam structure with several supporting beams 34 in the form of steel girders is provided on the basement base walls. These beams run in the longitudinal direction of the building and are supported on brackets 35 screwed to the inside of the base walls. The floor 33 itself consists of installation panels (e.g., screen-printed birch plywood panels with a roughened top surface) that rest on the supporting beams and are screwed to them.

[0033] Inside the housing 11, a partition wall 36 is provided at a short distance in front of the rear side wall section 23R, which ends at the top slightly below the roof section 29, so that a free space 37 extending across the width of the housing is formed between the roof section 29 and the upper end of the partition wall 36. The partition wall 36 divides the interior of the housing 11 into two sub-spaces, namely the main space 38 accommodating the power equipment, and a pressure guide shaft 39 separated from it by the partition wall 36, which is connected via a pressure equalization opening 40 provided in the floor 33 to the basement space 20 located below the floor and delimited by the foundation 16. As can be seen from the drawing, the floor below the switchgear 12 and the metering panel 13 is also open, so that there is a direct connection to the basement space below these two devices.If, for example, a short circuit occurs in the switchgear as a result of a fault during work on the switchgear, this is regularly associated with a significant increase in pressure and temperature. The resulting pressure wave propagates along the path of least resistance, initially downwards into the basement room 20 below the floor 33, then passes through the pressure equalization opening 40 upwards into the pressure guide shaft 39. From there, it passes through the free space 37 into the upper area of ​​the main room 38, where it poses only a minor danger to persons present in the main room. The door closing the door opening 32 can preferably be equipped with a ventilation grille through which the pressure wave can escape.

[0034] In the floor 33, in the rear area of ​​the housing 11, a hinged floor hatch 41 is pivotally mounted. Below this hinged floor hatch is an inspection opening 42 that provides access to the basement room 20. When closed, the floor hatch 41 is flush with the surrounding floor.

[0035] The switchgear 12 and the metering panel 13 located directly next to it each rest on support beams 34, which are dimensioned to easily bear the comparatively heavy weight of these devices. The switchgear and metering panel rest with their rear sides against one of the two longitudinal wall sections 34 or are located a short distance in front of it. The remote control cabinet 14, which is also provided, is mounted on the same longitudinal wall section slightly above and to the side of the metering panel. The meter cabinet 15 is located on the opposite longitudinal wall.

[0036] In the Fig. 5 to 7 are features which are similar to those of the first embodiment according to Fig. 1 to 4 are provided with identical reference numerals. As far as the features of both embodiments are evidently identical, they will not be described again below. The second embodiment according to the Fig.5 to 7 differs significantly from the first embodiment in that it comprises a transformer 42 as an additional power device, meaning that this embodiment is a substation with which current is transformed from the medium-voltage level (10 kV to 36 kV) to the low-voltage level (400 V). The station 10 of the second embodiment is overall larger than the first embodiment, with the intermediate partition wall 36 also provided here separating the main room 38 from an adjoining room 43. Unlike the main room, the adjoining room does not have a floor arranged above the foundation. The transformer 42 is arranged in the adjoining room 43, and is supported directly on supporting beams 34 at the level of the floor 33 in the adjacent main room. This ensures that the transformer is surrounded by air on all sides and that heat build-up cannot occur.

[0037] As can be seen, the secondary room 43 has a separate access door 44 in one of the two longitudinal wall sections 24, while the access to the main room 38 is located in the front side wall section 23V, just as in the first embodiment. Opposite the access door 44 to the secondary room 43 provided in the longitudinal wall section 24, a window opening 45 is provided in the other longitudinal wall section, which window opening is provided with a weather protection grille 46, so that air exchange with the environment is possible, but the entry of precipitation from outside into the interior of the housing is prevented.

[0038] The intermediate partition wall 36, which stands at the bottom of the foundation slab 17, is provided with several pressure equalization openings 40 below the floor 33 present in the main room 38 and which defines the upper limit of the basement room 20. In the event of a short circuit, the resulting pressure wave passes through these pressure equalization openings into the adjacent room 43 with the transformer 42 arranged therein. In this embodiment, pressure equalization with the environment can take place both via the window 45 and via the free space 37 above the intermediate partition wall into the main room and through its door opening 32 into the environment.

[0039] The station according to the invention, with its innovative construction, in which essential parts of the assembly are made of wood, offers significant advantages over known stations constructed entirely from concrete. Firstly, the wooden structure, with a specific weight of approximately 480 kg / m 3considerably lighter than a station building made entirely of reinforced concrete with a specific weight of 2,500 kg / m 3Overall, the lighter wooden structure allows for approximately 70% less construction weight compared to a reinforced concrete structure of comparable volume. Furthermore, the wooden structure offers considerable flexibility, as the dimensions of the stations are neither tied to prefabricated formwork units nor to fixed production facilities. In fact, the individual wall sections can be manufactured separately and transported to the station's installation site before being assembled with the foundation to form the overall housing. Each station body can be individually adapted to customer and network-specific requirements.While there are only a few fixed production locations for reinforced concrete station housings, and they can generally only be produced using a few prefabricated formworks, stations according to the invention can be manufactured without significant effort and with greater flexibility in dimensions and shapes, for example, the roof shape. In any case, the wall sections and the roof section can be manufactured by virtually any carpentry or joinery business. This significantly shortens delivery times compared to those for purely reinforced concrete stations. The CO2 footprint of the stations, which consist largely of wood, is considerably better than that of purely concrete buildings. QUOTES CONTAINED IN THE DESCRIPTION
