Description

Junction box for electrical cabling, and method of operation of the box. Field of the invention.

[0001] This innovation belongs to the field of Engineering, specifically in its technological aspect of modular infrastructure, more specifically, in a junction box developed for the interconnection of electrical cabling between the modules that make up each room of the modular data center system, such as electrical rooms, data rooms, redundant electrical rooms, cooling rooms and telecommunications rooms, but not limiting the invention to this single field, since the product can be applied in the most diverse technological areas of Engineering. BACKGROUND OF THE INVENTION

[0002] The demand for data center facilities has been steadily increasing with the rise in global connectivity. This growth directly impacts the capacity for data storage, processing, and control, which can be used in a wide variety of industries, businesses, offices, shopping malls, commercial establishments, and even leisure environments. All the technology applied in these diverse solutions relies on a data center for its operation.

[0003] The demand for data centers available for the completion of construction projects in periods of less than one year is a need that remains unsolved in the current state of the art, with traditional masonry constructions typically taking around three years, depending on the data center's capacity. However, the urgency for data centers to become operational requires that this development and installation time be reduced, potentially reaching a timeframe of less than six months, starting with contracting, then project development, manufacturing, transportation, installation, testing, and activation.

[0004] A modular data center system solution allows for the rapid availability of ready-to-use equipment. Therefore, solutions are needed that expedite the assembly of such systems in the modular data center installation area. One challenge of the current art is the electrical integration between the modules that make up each room of the modular data center system.

[0005] Furthermore, considering that the modular data center system has the flexibility to be expanded or reduced after it is already installed and in use, having a solution that allows for quick and easy connection and disconnection of the electrical cabling of each module in the room greatly facilitates and speeds up this process of expanding or reducing the operational capacity of the modular data center system.

[0006] In addition to the ease and speed of electrical connection, it is also necessary to ensure the safety of the data center; that is, the developed junction box needs to be secure enough to prevent any risk of disconnection of electrical cables during the room's operation. Furthermore, this solution must provide safe protection for people accessing the room for maintenance or any interventions.

[0007] Aiming to obtain a solution that resolves all the technical problems listed above, with all their adversities, this document describes the electrical cabling junction box used in the rooms of the modular data center system, capable of meeting all the requirements listed above.

[0008] Several solutions have been developed seeking optimization and improvements for data centers, more specifically in solutions for electrical cabling, given the need for and care required by these components.

[0009] In 2018, patent application US20210143595, whose family includes patent application BR 11 2019 018693-, entitled “QUICK CONNECTION DEVICE FOR EMBEDDED ELECTRICAL INSTALLATIONS”, described as a solution the use of a quick connection for embedded electrical installations; this solution is basically a combination of an electrical plug and socket for recessed lighting. The solution developed in patent US20210143595 aims to facilitate the installation of electrical equipment such as fans or light fixtures, in order to facilitate recessed installation.Although the purpose of this patent is to facilitate electrical installation, as does the developed solution, the specification requirements of the present solution are much more complex, since it demands the electrical installation of rooms used in a modular data center system, which are environments with very high energy consumption, and therefore require robust solutions, in addition to the safety risks and guarantee of the electrical installation's operation. Thus, it was necessary to develop an entire structure that meets these requirements, which is quite different from the plug and socket developed in patent US20210143595.

[0010] In 2017, patent application BR 102017013843-7 described a solution for connecting conduits in a junction box. Although it has the same scope as the solution described in this document, which is to provide a solution that facilitates connection in order to make it faster and more efficient, the solution proposed in patent application BR 102017013843-7 differs completely from the solution described in this document. The solution proposed in patent application BR 102017013843-7 is a small metal box, commonly used in residential electrical outlet installations, also known as a junction box, which was coupled to a conduit-type pipe using a bushing and a sleeve. Meanwhile, the solution developed in this document is much more complex, as it involves the electrical power supply of the entire modular data center system, with power loads that can exceed 36 Megawatts.

[0011] In 2002, patent US20020197910, whose family includes patent application PI 0205664-0, entitled “QUICK CONNECTION ASSEMBLY FOR ASSEMBLING ELECTRICAL INSTALLATIONS,” proposed a solution with a socket and receptacle mounted in a bell-shaped housing. The field of invention of patent application PI 0205664-0 considers suspended electrical installations, involving the assembly of the electrical installation. Although sharing the same field of invention, the solution developed in this document is a much more robust solution, since it aims to meet the entire installation's energy capacity demanded by each room in a modular data center system.

[0012] In summary, none of the documents available in the state of the art proposed the development of a junction box for electrical cabling in a modular data center system, designed to ensure safe coupling between the electrical cabling of each module that makes up a room. This solution is one of the technologies used to enable the operation of a modular data center system in a period of less than six months, while still guaranteeing all safety requirements and protection against electrical accidents, through a robust coupling system meticulously developed to ensure all these requirements.Another striking feature is its versatility in installation, as it can be quickly transported from different locations where it was initially installed, thanks to the decoupling solutions integrated into the junction box for electrical cabling, from the rooms used in the assembly of the modular data center system. OBJECTIVES OF THE INVENTION

[0013] The present innovation aims to develop a junction box for electrical cabling, used in the room modules of the modular data center system, capable of allowing easy and quick coupling between the modules.

[0014] Furthermore, the innovation also aims to provide robust insulation and electrical protection in the connection between the cabling of each module that is joined to form one of the rooms in the modular data center system.

[0015] The junction box also aims to ensure full availability for operation 365 days a year, without any interruption to data storage or processing operations, or other operations performed by the rooms of the modular data center system.

[0016] The aim of this solution is to resolve the difficulty between the operations of removing the electrical cabling from each module and re-routing the electrical cabling during the reassembly of the modules.

[0017] Furthermore, regarding the operation of the junction box, the objective of this solution is to develop a method that describes the operation of the junction box for the electrical cabling in the rooms of the modular data center system. BRIEF DESCRIPTION OF THE FIGURES

[0073] Because the modular data center system has the versatility of being fully manufactured in one factory and transported in modules only for assembly in the final area of ​​use, as well as the flexibility to be transferred from one area to another, all this movement of modules brings extreme difficulty to removing all the cabling from a module so that each module can be transported individually. Furthermore, it is necessary to reroute all the electrical cabling when reassembling the modules. All this difficulty in collecting dozens of meters of electrical cabling, transporting the modules, and rerouting all the cabling motivated the development of the innovation described in this document.

[0074] The electrical cable junction box is a component designed to organize and protect cable connections where feeder interconnections are required, in order to have a safe and orderly distribution in the module sections. The solution was designed to meet all needs and configurations through a quick and secure connection, facilitating installations that, without the junction box, would require extensive work to remove all the electrical cable installations and then reroute them between modules. The developed box ensures safety and functionality, as it keeps cable connections neatly organized and accessible, preventing overloads and problems in the electrical system, thus guaranteeing total operational safety.

[0075] To ensure cable connections at critical points in the connections between feeders installed in the electrical room, or in the redundant electrical room, or in other rooms of the modular data center system, which require branch lines to allow the separation of modules for their respective individual transport and to facilitate a quick and safe connection at the time of coupling the modules, avoiding the installation difficulties and possible connection failures already mentioned above.

[0076] In order to show how the solution is used in the structure of a modular data center system, Figure 1 presents a front perspective view of the modular data center system. In this view, it is possible to visualize the data room, the cooling room, the electrical room, and the redundant electrical rooms. Figure 1 also indicates the orthogonal axes X, Y, and Z. The X-axis indicates the longitudinal direction of the structures, a dimension also known as the length of the structures; the Z-axis indicates the transverse direction of the structures, a dimension also known as the width of the structures; and finally, the Y-axis indicates the direction parallel to the height of the structures.

[0077] The previous perspective view, illustrated in Figure 2, shows another configuration for a modular data center system, which consists of two data rooms, two cooling rooms, one electrical room and two redundant electrical rooms, and a telecommunications room, which is not visible in this figure. Other alternative configurations can be used, since one electrical room and two redundant electrical rooms can accommodate different numbers of data rooms, potentially up to 12 data rooms, depending on the total capacity required by the modular data center system.

[0078] In order to demonstrate various applications for the developed solution, Figure 3 is presented, which is a front perspective view of the electrical room used in a modular data center system. This figure allows visualization of the external geometry of the room structure, in which the junction box is mounted in the internal area of ​​the room, within the modular data center system.
