Modular substation

Abstract

The invention relates to a modular substation arranged on two superposed planes: an upper plane, at ground level, where elements for operation and periodic maintenance (medium-voltage switching and control, low-voltage board and meter enclosure) are accommodated, and a lower, underground plane that includes the transformer, a firewall system and an oil containment pit. The system is organised across four different types of compartment: (A) an underground reinforced polyester chamber for the transformer and ducts; (B) a projecting stainless steel and aluminium interface that connects the chamber to the outdoor enclosures and facilitates ventilation and access; (C) a central cabinet for medium- and low-voltage distribution and control cells; and (D) side enclosures for low-voltage boards, meters and communication systems.

Description

[0001] MODULAR TRANSFORMATION CENTER.

[0002] OBJECT OF THE INVENTION

[0003] The present invention, Modular Transformation Center, refers to a metal building in its aboveground part and an underground chamber made of fiberglass-reinforced polyester on a reinforced metal frame that forms a lost formwork in its underground part, located on a reinforced concrete slab resting on a bed of compacted sand and gravel, to house an Electrical Power Transformation Center, for industrial or urban use, which originates as a single Transformation Center unit and in a modular way can be folded and / or duplicated according to the present or future needs of the installation, in addition to its exterior being able to adopt an aesthetic appearance that blends in with the urban scene.With an aesthetic appearance similar to current traditional industrial transformer substations, but with greater transformer capacity than current models, motivated by its architectural design and the current and future trend of using electricity as clean energy, with a significantly reduced footprint, improving upon those used by various electricity distribution companies worldwide to provide low-voltage power to domestic, commercial, and industrial users, and in this case, adapting to multiple needs due to its modular design. This situation motivates the European Union to regulate energy efficiency and impose stricter requirements on transformer losses, as well as the future elimination of highly polluting gases such as sulfur hexafluoride (SF6), widely used in these medium-voltage power distribution systems. FIELD OF THE INVENTION.

[0004] Currently, there is a large number of buildings on the market, made of masonry, prefabricated in concrete or metal, above ground or underground, or even inside residential buildings, with multiple electrical typologies, and for operation or maintenance with interior or exterior execution, with powers equal to or less than this presented invention.

[0005] Each electricity distribution company defines the preferred energy class for its installations, with Class 10 being the most common. This means that the transformer, whether located outdoors or inside a dedicated building, only increases in capacity (at < 10k), prioritizing natural ventilation (ONAN). Due to the general typology and architecture prevalent worldwide, most buildings place all their transformer substation components on the same level, thus limiting their power output or requiring a significant increase in the size of the air inlets and outlets, and / or the use of forced ventilation (ONAF), with the consequent energy expenditure, thereby worsening the overall energy rating.

[0006] Typically, buildings for this industrial application worldwide, as previously mentioned, are prefabricated in concrete, metal, surface-mounted, underground, etc., but all of them are large and heavy, requiring special transport from the factory to their destination. This makes their installation difficult in any industrial location, but they are completely unfeasible in urban areas, given the foreseeable future power demands, especially if they are transported, as is usually done, fully installed with all their components inside from the factory.Technological evolution and occupational risk prevention, as well as the emergence of new markets driven by climate change and the demand for low CO2 emissions, are prompting a significant increase in the power capacity of transformer substations, both for users and distributors. This is motivated by the anticipated greater use of electrically powered systems by automobiles and domestic heating and cooling systems, or to allow the National and / or Local Grid to absorb excess local micro-generation, with the aim of gradually abandoning the obsolete energy sources we currently use, polluting energy sources based on hydrocarbons.

[0007] With the invention of the Modular Transformer Center (CTM), current building design and manufacturing are improved, reducing their footprint and volume per unit, and allowing for easy future expansion. Being exterior-facing (non-habitable), it avoids potential extrication of maintenance workers due to electrical accidents in confined buildings above ground level or underground. The Modular Transformer Center can be integrated into the urban landscape or for industrial use and is easily transported between national and international warehouses using ordinary TIR-type vehicles, as well as the vehicles commonly used in this type of installation, such as trucks with integrated cranes capable of handling loads of less than 10 tons.

[0008] BACKGROUND OF THE INVENTION

[0009] On November 6, 2002, the same author of this improvement, ES200202680U, presented the Special Urban Transformation Center (CeTur), later expanded to a patent registered in Canada, the USA, Mexico, Brazil, Australia, Japan, China, and a European patent. This design was conceived solely to meet the standardized power requirements of urban distribution companies, aiming to create a technological hub that would integrate seamlessly into the urban landscape. However, its design, particularly its limited space, makes it unsuitable for use as a customer-owned transformer substation with current and foreseeable future power demands. It was only applicable to the distribution company's own transformer substation.The CTM, as an invention, also improves upon ES200202680U of November 2002. At that time, the defined advertising was static, installed on doors and light boxes with an aluminum structure. New technologies allow for more efficient industrial-grade LED lighting, and even the placement of outdoor LED monitors in the light box spaces, implemented with brightness control and programmed diffusion from a center for the creation or reproduction of advertising or informational content of interest to the citizens of the municipality and for its benefit.

[0010] DESCRIPTION OF THE INVENTION

[0011] The invention now presented, CTM, improves upon all aspects of the previous invention, such as:

[0012] 1) Increased power and size due to reduced losses in the new transformers.

[0013] 2) Future forecast of SF6-free cells, according to EU standards.

[0014] 3) Height-adjustable skids, so that the transformer pumps always exceed zero level.

[0015] 4) Prefabricated underground chamber, made of fiberglass reinforced polyester, assembled on site, guaranteeing watertightness between external vertical and horizontal walls for water inlets or the outlet to the adjacent land of possible oil spills from the transformer.

[0016] 5) Firebreak between the spilled oil reservoir and the transformer.

[0017] 6) Possible installation of an automatic free discharge fire suppression system.

[0018] 7) Improved broken ventilation ducts, which evacuate heat from the higher power transformers.

[0019] 8) In an underground chamber, with separators and windows that direct the flow of cold air to the base of the transformer and allow the sampling of the transformer oil from the base of one of the cabinets installed one to the right and left of the central cabinet. 9) Entrance / Exit of Ground cables, Medium Voltage, Low Voltage and control fiber optics, etc.

[0020] 10) The emerging section is constructed of stainless steel and internally overlapped aluminum panels to attenuate electromagnetic radiation. 11) Modular panels, either externally or internally, display static or dynamic LED TV screen advertising, integrable into the urban landscape. 12) Modular construction with independent cabinets for each application.

[0021] 13) Multiple architectures of one to four CTM units, forming the Transformation Center as independent or centralized.

[0022] 14) Configuration of Electric Charging Station, Bus Stop for urban or industrial use.

[0023] 15) Exterior coverage in the form of an advertising landmark or kiosk, “Technological Island”.

[0024] 16) Greater travel of incandescent gases and / or materials projected by short circuit in Medium Voltage cables or switches.

[0025] Gases and materials are expelled to the outside through the ventilation inlets / outlets of the assembly due to overpressure. The longer and more convoluted the path, the less harmful the effect. Figure 3 shows the trajectory of gases and material fragments exiting through (19). These travel a long distance through the ventilation ducts before reaching the outside and are attenuated by the convoluted design of the ventilation ducts, which forces them to change direction.

[0026] The CTM consists of arranging the different elements on two superimposed planes: on the upper plane at zero level, the elements of periodic manipulation, such as switching and control of the medium voltage, low voltage panel and metering cabinet of the electric distribution company and on a lower and underground plane, the transformer, firebreak and pit for possible spilled oils.

[0027] The aforementioned elements are located in four distinct cabinets or chambers, both for distribution company applications and for customer applications, consisting of:1 o Underground chamber made of fiberglass-reinforced polyester and armored (A) in (figure 1). - Intended to house the power transformer, ground cable entry / exit, communication and control, medium and low voltage, and fresh air intake ducts to the lower part of the transformer station.

[0028] 2 oStainless steel and aluminum interface, emerging above zero level (B) in (figure 1). - Intended to mechanically connect the underground chamber with the exterior cabinets, it incorporates ventilation inlets and access doors to the transformer pump cover.

[0029] 3 o Central Cabinet of Stainless Steel and Aluminum above ground level (C) in (figure 2). - Intended to house the control and switching cells, Medium Voltage input / output and Low Voltage output to its control panel.

[0030] 4 o Stainless steel and aluminum cabinets installed one to the right and one to the left of the central cabinet (D) in (figure 2). - Intended to house the Low Voltage panels, Meters, Communication, etc. and one with a floor-mounted access.

[0031] This new arrangement improves upon that presented in ES200202680U by separating components according to operating voltages and functions into independent cabinets, thus limiting handling based on the qualifications of maintenance personnel. Its entire construction and transport to the construction site are fully modular. It also improves the intake of fresh air to the base of the transformer via ducts with headers and labyrinths from the inlet grilles (8) located above ground level. At the bottom of the underground chamber, there is a reservoir or pit and an outlet for connection to the sewer system from the air inlet. These modifications to the ductwork thus promote natural draft and evacuate all the heat through the outlet grilles (9).

[0032] The broken shape of the ventilation labyrinths (1) and their arrangement guarantee the attenuation of the noise produced by the transformer and the vibrations are attenuated by placing it on rubber elements, as well as the composition of its walls of the whole emerging assembly in Stainless Steel and Aluminum attenuates the radiations of the Electromagnetic Field, and finally these ducts also serve to conduct the incandescent gases and material released in a possible short circuit in cables or medium voltage switching elements, channeling them to places of minimal impact, due to the broken arrangement of these labyrinths and because the exits to the outside are very far away from the maintenance operators or any passerby during the period in operation of the CTM;highlighting that the possible gas outlets would be located approximately 2.9 meters above the ground and would do so after having traveled approximately 2.1 meters in the opposite direction to the safety valves directed to the CTM pit, having been distributed part of those gases by the fresh air inlets, having had to overcome the inertia of the system supported by ONAN flow, and after having traveled approximately 3 meters, being released through the fresh air inlet windows, located between +0.2 and 0.5 meters above zero level.;

[0033] The aforementioned data is guaranteed even for maintenance, shutdown, or commissioning operations of the installation, with open access doors to the medium-voltage switchgear (cells and / or RMU), as these are framed with deflectors (17) (size according to type and manufacturer) that prevent gases from escaping to the front. Basic factory-installed or custom interlocks, as requested by the end customer, are incorporated into the inspection or access doors to the transformer. The above reflects an enhanced and unusual level of safety for buildings of this type worldwide (see Figure 3).

[0034] The semi-buried transformer is installed on skids between height-adjustable rails (12), thus adapting to any first installation power or manufacturing design, ensuring that the active parts, pump cover (2), are not affected by water runoff or occasional flooding.

[0035] The improvement also extends to a perforated plate (4) with a few small holes that allows the passage of any spilled oils and limited oxygenation into the polyester pit (6), acting as a natural firebreak. This plate is located between the skids and the pit, covering the entire surface. The aforementioned reservoir or pit has sufficient capacity to hold the oil from any installed transformer and is made of fiberglass-reinforced polyester, guaranteeing watertightness and preventing contamination from leaks into the subsoil (Figure 2).

[0036] The Modular Transformation Center (CTM) is designed in a “modular” way, composed of four (A, B, C and D) types of rooms:

[0037] A) Underground chamber for the transformer.

[0038] B) Interface made of stainless steel and aluminum sheet.

[0039] C) Cell cabinet made of stainless steel and aluminum sheet.

[0040] D) Low Voltage Switchgear Cabinets also in Steel Sheet, Stainless Steel and Aluminum.

[0041] Their dimensions and weights will be adapted to ordinary conventional TIR transport, they can also be transported to the construction site from the local warehouse with an open box truck / crane with urban maneuverability.

[0042] The cabinets will be constructed of stainless steel sheet and aluminum sheeting, cut and folded, and assembled at the factory using a riveting machine and minimal TIG welding. On-site, the different compartments (A, B, C, D) are quickly assembled with stainless steel screws. CTM represents an innovation in its manufacture, assembly, and installation, and improves its national and international transport (Figure 9).

[0043] A) Underground Transformer Chamber. - Located below ground level, constructed using prefabricated fiberglass-reinforced polyester panels, consisting of a base and four side panels assembled and their joints waterproofed on site with a strip of fiberglass roving applied with a roller using polyester resin and catalyst. A top frame or base of the emerging metal structure is installed, with oval bolts in the highest area aligned with ground level, leveling the entire system from this point. Adjustable fastening elements for the transformer skids (12) (Figure 2), firestop plates, and a polyester pit will be installed at the bottom, along with neoprene strips on the transformer skids, a firestop plate (4), and a polyester pit (6) for collecting any spilled oil.The aforementioned upper frame will have threaded holes to hold the M16 nut base, the first interface body (B) will be screwed onto the frame (figure 1).

[0044] B) Interface Structure and Access to Transformer Pump Cover. - Lower part of the central pop-up body of each unit, each face starts with a rectangular structure made of stainless steel sheet in the shape of a (C) with the face open to the interior, joined together with screws and by Serbloc Inox rivets and / or screws, and closed with stainless steel and aluminum sheets previously bent at an angle to be riveted, repeating the operation until the desired height is reached. The aforementioned internal structure rigidifies the assembly, and provides it with access and inspection door frames for the Transformer and fresh air intake vents for ventilation (8) with insect screen, formed by inverted V / A shaped louvers (8), two front doors with grounding and retention (11), on frames with neoprene gasket to increase watertightness, these doors will give access to the transformer pump cover (2).The entire prefabricated assembly is installed on site on the chamber built in polyester and flush with zero level, this Interface emerging to place the Cell Cabinet (C) on it.

[0045] C) Switching Cabinet or Cells. - The upper part of the central body of each unit, installed and bolted with 4 screws onto the structure (B), and without a bottom, i.e., connected to the central part of the underground polyester chamber through the gap between the right and left ventilation inlets. The switching units will be housed in it. The cabinet will have ventilation outlets (9) at its top, crowned by a flat roof superimposed like a drip edge (16), and at the indicated height, windows for the exit of low-voltage cables towards the top of the Low-Voltage Panel (21).At the front, a double hinged door (10) with its corresponding retainers and grounding points, and with a handle and master key lock of the property, these will give a view to the front of the cells framed by deflectors (17) that prevent the escape of gases to the front in case of a short circuit in the switches or cable box, also having access at the bottom to the basic interlocking bolts for the transformer doors, being able to install interlock with a special key at the request of the client, for its installation on site, eye bolts on the flat roof for its lifting with a crane (16).

[0046] D) Low Voltage Switchgear Cabinets. - Installed at the head on the shorter side of the rectangle, with a workable floor, for the passage of Low Voltage output cables and / or for taking transformer oil samples, above the air inlets for ventilation, they will have hinged access doors (13) with retainers and earthing points; for the Distribution Company version, entry / exit through the workable ventilations from the inside that allow access and quick connection to the LV Switchgear of the voltage coming from an emergency Generator Set to guarantee the supply.

[0047] From what has been stated so far, it is clear that the CTM invention, resulting from the experience of units in operation, constitutes many improvements to ES200202680U, in terms of novelty, inventive activity and industrial application, also allowing for easy reuse of the material used at the end of its useful life as a transformation center, having primarily used stainless steel and riveted aluminum. Regarding the aesthetic finishing material for this model or that used in the external enclosure, anodized or lacquered aluminum and tempered or laminated glass will be used in the advertising or citizen communication areas, thus following the criteria already established.

[0048] The modular construction of the invention of independent cabinets per application generates multiple architectures of one to four independent or centralized transformation centers (figures 5 and 6), enabling spaces for other services, such as Bus Stop (figures 7 and 8) with all the inherent and updated services such as industrial or urban Electro-charging station, such as high power converters for Ultra Fast Chargers, public use Wifi systems for public transport users, information panels of services and expected delay times online, banks, etc.

[0086] PREFERRED MODE OF EMBODIMENT

[0087] The construction of all cabinets and metal protruding parts will be made of Stainless Steel, as indicated in section B) and reinforced with overlapping Aluminum panels to mitigate electromagnetic radiation.

[0088] The Modular Transformer Substation invention, being an enclosure for electrical equipment intended for transforming distribution voltage to domestic or industrial consumption voltage, is characterized by being designed to accommodate transformers and switchgear standardized in the EU and many other countries with equivalent requirements and regulations. This situation further motivates the modular design, expanding the invention's functionality by allowing the assemblies to be built and transported by ordinary means (Mega Tir) from the factory to the distributor's warehouse in the destination country. The four or five sides of each metal or polyester assembly form a "complete modular unit," with assembly at the destination, saving space and weight during transport and adapting to domestically manufactured electrical equipment and / or continental European regulations.

[0089] For the installation of the CTM on site, an excavation must be made for the prefabricated and modular reinforced polyester structure (the underground Chamber (A)), placing the slab at the bottom on a leveled and compacted gravel bed, prior to the implementation of the necessary electrical grounding system according to the standard project of the distribution company in the area. With the help of the crane of the truck that transports the slab and the 4 sides to the site, they will be unloaded and placed assembled by means of the metal fittings that guarantee the continuity of the grounding of the mesh of the reinforcement, at the appropriate depth and the position indicated by the person in charge of the work, finally we will cover the joints with a strip of fiberglass roving applying polyester resin and catalyst with a roller and we will ensure the watertightness of the grounding inlet conduits, medium voltage inlets / outlets, low voltage outlets, as well as the communications.For backfilling the excavation, we will apply compacted gravel with a diameter of approximately 2 cm, and on top, at the appropriate height, tape indicating the presence of tensioned pipes. The metal parts emerging from the CTM will be bolted to the structure of the Chamber (A) with assembly B) Interface then in assembly C) Switching Cabinet or cells with their corresponding Low Voltage Cabinets D) installed in a backpack configuration.

[0090] Having thus completed the installation of the CTM enclosure, the electrical installation of the Medium and Low voltage switchgear of the CTM then began.

[0091] In the CTM-Bus Stop versions, the CTM installation is identical to that defined above, adding a roof to the CTM assemblies and banks (18) of the waiting area, as well as the metal structure to place the high power converters for Ultra Fast Chargers with the configurations of (figures 7 and 8).

[0092] The CTM, due to its modular construction, starting with a single module, can also be covered by a second aesthetic envelope in the form of a Kiosk or Technology Island (20), with the final designation of CeTur-CTM, see (figure 4). Its installation involves the internal part, identical to that previously defined, while the external aesthetic part rests on a base bolted to the concrete structure. Four columns are bolted to this base and braced with an upper counter-base to which the elliptical polyester roof is secured, with a perforated lower section for the evacuation of heat produced by the transformer.

[0093] It will have two front doors, one sliding with concealed tracks and the other fixed. Above these are hinged doors, and at the rear, a light box for static advertising and / or space for an outdoor LED TV monitor for dynamic advertising. At the front, the doors will be hinged with their corresponding retainers, and the light box or signage changes will be carried out from the inside, as will any operation or intervention on the outdoor LED TV monitors.Regarding transport, each MegaTir can carry two complete units (Figure 2) or one unit (Figure 7), without switchgear. This differs from traditional compact or modular prefabricated concrete buildings, which exceed the MegaTir's transport weight limits, capped at 24 tons of payload and 3 meters in height. These traditional buildings require special transport with gondola-type platforms and open boxes to avoid exceeding the minimum clearance or gauge of European roads. In contrast, the CTM, due to its modular design, can be transported with two units per MegaTir, based on weight and dimensions, as shown in Figure 9.
