Description

Technical Field

[0001] The present invention relates to the technical field of power distribution equipment, and more particularly to an integrated power distribution input and output module and a power distribution control cabinet. Background Art

[0002] When designing the installation of the power distribution module, the existing installation modules cannot be flexibly matched and installed, and the overall structure is relatively scattered. During installation, since each module needs to be installed one by one, the efficiency is low, the installation is inconvenient, and it is difficult to quickly and reasonably configure them together. During specific installation, the installation of each power distribution module inside the power distribution equipment is also relatively inconvenient, and the position is not easy to adjust. The scattered modules often lose sight of one another during installation. Faced with the current complex and changeable power distribution needs, the adaptability is even worse. Therefore, how to scientifically configure the input and output modules into a whole for modular installation to achieve a compact structure and flexible installation and use is one of the problems that technical personnel in this field urgently need to solve. Summary of the Invention

[0003] The problem to be solved by the present invention is to provide an integrated power distribution input and output module and a power distribution control cabinet in response to the above-mentioned deficiencies in the prior art, which solves the problem that the power distribution modules in the prior art are arranged in a dispersed manner and need to be installed one by one, resulting in inconvenience in installation and maintenance and poor adaptability.

[0004] To achieve the above-mentioned purpose, the present invention adopts the following technical solution: an integrated power distribution input and output module, comprising a metal frame and module components installed in the metal frame, the metal frame comprising four vertically arranged longitudinal beams and four connecting plates for connecting the four longitudinal beams, the connecting plates being fixedly connected to the top ends of the longitudinal beams, the longitudinal beams comprising two integrally formed beam plates arranged perpendicular to each other, a "Π"-shaped strip groove being formed between the two beam plates, the openings of the strip grooves of the two longitudinal beams being arranged opposite to each other, and the inner side areas of the right angles formed by the two beam plates being arranged toward the inner side of the metal frame; below each connecting plate on the left and right sides, parallel to it, A terminal base plate is installed on the ground, and the terminal base plate is bent from a piece of steel plate. The bending process forms a bucket-shaped structure with five sections of plates, wherein the first plate is arranged horizontally and one side of its free end is provided with two spaced connecting ear plates vertically downward. The other end of the first plate, the second plate, the third plate, the fourth plate and the fifth plate are sequentially connected to each other; a copper drain bracket is also installed under the front and rear connecting plates. The copper drain bracket is bent from a strip of metal plate, and its upper and lower edges are bent 90 degrees toward the inside of the metal frame, and the width of the upper bent part is smaller than the width of the lower bent part;

[0005] A PCB mounting base is also installed between the two longitudinal beams, and the PCB mounting base is spaced and located directly above the terminal base. Two module mounting ears are installed opposite each other on the top of the metal frame. The module mounting ears are angle steel structures and their ends are detachably fixed to the ends of the longitudinal beams. An integrated module panel is installed between the two module mounting ears and is installed on the top of the metal frame in an overlaying manner.

[0006] A guide rail plate is also closely mounted on the surface of the third plate body facing the inner side of the metal frame. The guide rail plate is arranged perpendicular to the longitudinal beam. A guide rail fuse and input wiring terminals are mounted on the guide rail. Output wiring terminals also located in the metal frame are mounted on the guide rail on the side directly opposite to the guide rail fuse.

[0007] An input circuit breaker mounting base plate is installed directly below the integrated module panel. The two opposite sides of the input circuit breaker mounting plate are respectively fixed to the first auxiliary plate and the second auxiliary plate. The first auxiliary plate is located directly above the PCB mounting base plate and its two ends are respectively fixed between the two longitudinal beams. The second auxiliary plate is arranged opposite and parallel to the first auxiliary plate. The two ends of the second auxiliary plate are respectively clamped and installed between the upper and lower bent parts of the copper busbar bracket.

[0008] The integrated module panel is also equipped with a hot-swappable secondary system module and an integrated module output circuit breaker. Furthermore, an auxiliary extraction mechanism is installed at each end of the hot-swappable secondary system module. The auxiliary extraction mechanism includes a fixed core shaft and a hinged ejector. The core shaft is vertically and fixedly installed at the end of the connecting plate. A hook-shaped ejector is hinged on the core shaft. The ejector includes an ejector hook and an operating arm. The corner of the ejector hook is hinged to the core shaft, and the operating arm extends out of the metal frame. When the extraction operating arm rotates toward the outside of the metal frame, the ejector hook ejects the end of the mounting plate for installing the hot-swappable secondary system module out of the metal frame. Furthermore, the integrated module panel is also equipped with a module input circuit breaker, a module lightning arrester, and a backup protection circuit breaker. The integrated module output circuit breaker is located between the module input circuit breaker and the hot-swappable secondary system module.

[0009] Among them, except for the angle formed by the fourth and fifth plates of the terminal base, which is a right angle, the angles formed by the other plates are all obtuse angles. The fifth plate is parallel to the first plate. The connecting ear plate and the fourth plate are vertically attached to the same side wall of the strip groove and fixedly connected thereto.

[0010] In addition, a U-shaped groove is punched on the left and right ends of the surface of the vertical part of the copper hollow bracket. Each groove protrudes toward the outside of the metal frame when punched, and the open ends of the U-shaped structures of the two grooves are away from each other.

[0011] Alternatively, both sides of the PCB mounting base plate may extend into the right-angle region formed by the two beam plates of the two longitudinal beams, and be tightly fixed to at least one of the beam plates.

[0012] Specifically, the guide rail plate has a cross-section in the shape of a Chinese character "X," with a groove in the middle, both sides of which extend horizontally outward. Several wire tie holes are provided along the length of the groove bottom. Finally, several output copper busbars are suspended and fixed below the copper busbar bracket.

[0013] At the same time, the present invention also provides a power distribution control cabinet, which mainly includes a cabinet body, and any of the above-mentioned integrated power distribution input and output modules is installed in the cabinet body.

[0014] Compared with the prior art, the present invention has the following beneficial effects: it transforms the original manual workshop-style assembly into a standard component assembly line, resulting in standardized products, reliable performance, good consistency, and significantly improved assembly efficiency. The present invention pre-centrally installs the power distribution modules, mainly input and output modules, together in a scientific and reasonable structure. The pre-assembled integral components formed by the input and output modules are directly installed in the corresponding cabinet or distribution box, so that the modules can be well arranged in a metal frame, with high integration and easy overall position adjustment, achieving an efficient and streamlined modular electrical design with strong adaptability. In particular, when the metal frame is used to install the input and output modules, the corresponding modular components that can be installed inside are densely packed, diverse in variety, and high in quality, meeting electrical safety regulations, ensuring sufficient internal space within the limited frame size, minimizing the space occupied by the frame itself, while ensuring the frame's structural strength, deformation resistance, installation and connection capabilities, and regular appearance, which is conducive to batch assembly, operation, and large-scale production. Other advantages, objectives, and features of the present invention will be partially reflected in the following description and will also be understood by those skilled in the art through research and practice of the present invention.

DETAILED DESCRIPTION

[0030] In order to make the technical means, creative features, objectives and functions of the present invention clearer and easier to understand, the present invention is further described below with reference to the accompanying drawings and specific embodiments:

[0031] This embodiment specifically proposes an integrated power distribution input and output module, the structure of which mainly includes a metal frame and module components installed in the metal frame, such as Figure 9 The metal frame of this embodiment is made of several profiles that can be detachably connected and fixed. These profiles are mainly used to build the main structure of the metal frame structure. Specifically, it mainly includes four vertical longitudinal beams 1 and four connecting plates 3 for connecting the four longitudinal beams 1. The four longitudinal beams 1 can stand on the ground to support the entire metal frame. The connecting plates 3 are fixed to the top of the longitudinal beams 1 to form a rectangular frame structure. The longitudinal beams 1 of this embodiment include two integrally formed beam plates that are perpendicular to each other, that is, Figure 13 The first beam plate 16 and the second beam plate 17 shown in the figure form a "Π"-shaped strip groove 15 between them after being bent. When forming the metal frame, the openings of the strip grooves 15 of the two longitudinal beams 1 are arranged opposite each other, and the right-angled inner area formed by the two beam plates is arranged toward the inside of the metal frame. That is, the planes on the inner side of the metal frame on which the two beam plates are located intersect perpendicularly to form the above-mentioned right-angled inner area. At the same time, a terminal base plate 2 is installed parallel to each connecting plate 3 on the left and right sides, as shown in FIG. Figure 10-12 As shown, the terminal base plate 2 is formed by bending a piece of steel plate, and a bucket-shaped structure with five sections is formed by the bending process, wherein, see Figure 11 The first plate body 9 is arranged horizontally and one side of its free end is provided with two spaced connecting ear plates 8 vertically downward. The other end of the first plate body 9, the second plate body 10, the third plate body 12, the fourth plate body 13 and the fifth plate body 14 are successively connected to each other. Except for the angle formed by the fourth plate body 13 and the fifth plate body 14, which is a right angle, the angles formed by the other plates are all obtuse angles. The fifth plate body 14 is parallel to the first plate body 9. The connecting ear plate 8 and the fourth plate body 13 are vertically attached to the same side wall of the strip groove 15 and fixedly connected thereto.

[0032] See also Figure 1-4In this embodiment, a PCB mounting base plate a1 is further installed between the two longitudinal beams 1. The PCB mounting base plate a1 can be made of a rectangular steel plate, and the PCB mounting base plate a1 is located at intervals directly above the terminal base plate 2. Two module mounting ears a3 are installed opposite to each other on the top of the metal frame. The module mounting ears a3 are angle steel structures and their two ends are detachably fixed to the ends of the longitudinal beam 1. An integrated module panel a10 is installed between the two module mounting ears a3. The integrated module panel a10 is installed at the top of the metal frame in a covering manner. A guide plate a13 is also tightly installed on the surface of the third plate body 12 facing the inner side of the metal frame. The guide plate a13 is a strip-shaped structure. On the one hand, the corresponding electrical components can be installed. On the other hand, the electrical components can be slid on its surface and fixed when they slide to the appropriate position.

[0033] More specifically, the front guide rail plate a13 is preferably installed perpendicular to the longitudinal beam 1. The guide rail is mounted with a guide rail fuse and input terminals, and the guide rail opposite the guide rail fuse is mounted with output terminals also located within the metal frame. Simultaneously, an input circuit breaker mounting plate a11 is installed directly below the integrated module panel a10 of this embodiment for mounting the input circuit breaker a15. The two opposing sides of the input circuit breaker mounting plate a11 are respectively fixed to a first auxiliary plate a2 and a second auxiliary plate a16, thereby achieving a fixed connection between the mounting plates. The first auxiliary plate a2 is located directly above the PCB mounting base plate a1, with its ends fixed between the two longitudinal beams 1. The second auxiliary plate a16 is positioned opposite and parallel to the first auxiliary plate a2. The ends of the second auxiliary plate a16 are respectively snapped into place between the upper and lower bent portions of the copper busbar bracket 4, enabling quick and secure installation and facilitating assembly and positioning.

[0034] As a specific implementation detail, the entire integrated module panel a10 is also equipped with a hot-swappable secondary system module a5 (the structure of the hot-swappable secondary system module a5 is not shown in detail in the figure) and an integrated module output circuit breaker a7. The hot-swappable secondary system module a5 is installed on the corresponding strip-shaped carrier board, such as Figure 2 As shown, an auxiliary pulling mechanism a6 is installed at each end of the hot-swappable secondary system module a5, which is used to pull out the front hot-swappable secondary system module a5, or to lift it upward and remove the carrier board. Figure 7-8As shown in the structure, the entire extraction-assisting mechanism a6 includes a fixed core shaft a61 and a hinged ejector, wherein the core shaft a61 is vertically and fixedly installed at the end of the connecting plate 3, and a hook-shaped ejector is hinged on the core shaft a61, and the ejector includes an ejector hook and an operating arm, wherein the corner portion of the ejector hook is hinged to the core shaft a61, and the operating arm extends out of the metal frame, and when the extraction operating arm rotates toward the outside of the metal frame, the ejector hook will eject the end of the mounting plate for installing the hot-swappable secondary system module a5 out of the metal frame, thereby realizing quick and labor-saving disassembly.

[0035] Further, if Figure 1-2 , a module input circuit breaker a9 and a module lightning arrester, as well as a backup protection circuit breaker, are also installed on the integrated module panel a10. The integrated module output circuit breaker a7 is located between the module input circuit breaker a9 and the hot-swappable secondary system module a5. In addition, for the above-mentioned metal frame, except for the right angle formed by the fourth plate 13 and the fifth plate 14 of the terminal base plate 2, the angles formed by each of the other plates are all obtuse angles. The fifth plate 14 is parallel to the first plate 9. The connecting ear plate 8 and the fourth plate 13 are both vertically attached to the same side wall of the strip groove 15 and fixedly connected thereto. In addition, a UU-shaped groove 7 is punched on each of the left and right ends of the surface of the vertical part of the copper exhaust circuit breaker bracket 4. Each groove protrudes toward the outside of the metal frame when it is punched, and the open ends of the U-shaped structures of the two grooves face away from each other.

[0036] Regarding the specific mounting structure of the aforementioned PCB mounting base a1, the two sides of the PCB mounting base a1 can also extend into the right-angled area formed by the two beams of each of the two longitudinal beams 1, and be tightly fixed to at least one of the beams, stably mounted on the metal frame. Regarding the aforementioned guide rail plate a13, during actual processing, its cross-section is shaped like an "X" (a cross-section), with a groove in the center and two sides extending horizontally outward. The bottom of the groove in the center is provided with several wire tie holes along its length to facilitate the installation and adjustment of the position of electrical components. As for the output copper busbars a14, several of them are also suspended and fixed below the copper busbar bracket 4, making the arrangement more compact and reasonable.

[0037] As another recommended structural design, please continue to refer to Figure 11, a plurality of rectangular perforations are also provided on the second plate 10, and each rectangular perforation has two limit bars 11 protruding from the long side toward the plane where the rectangular hole is located. The limit bars 11 are T-shaped, and each limit bar 11 includes a rectangular plate and a strip plate. The rectangular plate is located at the end of the strip plate and is integrally connected to it. The terminal base plate 2 also constitutes a component of the frame after being connected to the frame, significantly improving the overall strength and stability of the frame. It can be used to install and fix 35mm standard guide rails and guide rail terminals, circuit breakers and other electrical accessories. Cable bundling positions can be set on its surface to facilitate cable management, maintain appropriate curvature, and prevent safety risks caused by expansion and contraction deformation. A cable path management label area can also be provided on the corresponding plate, such as the fourth plate 13, to make cable path management concise and clear, and to simplify the product module assembly process, thereby improving product assembly quality and assembly efficiency. The specific size processing should be that the terminal base plate 2 has a height of 200mm to 500mm, a width of 100mm to 200mm, and a depth of 30mm to 60mm, which can basically meet the installation and use of existing conventional electrical components without additionally expanding the space structure.

[0038] Based on the above structure, a copper drain bracket 4 is also installed below the front and rear connecting plates 3 of this embodiment. Figure 15-16 The copper busbar bracket 4 is also formed by bending a strip of metal plate. Specifically, its upper and lower edges are bent 90 degrees toward the inside of the metal frame, and the width of the upper bent part is smaller than the width of the lower bent part. The surface of the lower bent part is provided with a number of screw holes, which serve as the working surface for fixing the mounting guide rail of the busbar and the working surface for fixing the copper busbar insulator. A U-shaped groove 7 is punched on each of the left and right ends of the surface of the vertical part of the copper busbar bracket 4. Each groove protrudes toward the outside of the metal frame when punched, and the open ends of the U-shaped structures of the two grooves deviate from each other, thereby improving the bracket's anti-bending and anti-torsion strength and ensuring the stable position relationship of the electrical accessories. In addition, as shown in Figure 8, the copper busbar bracket 4 can also be provided with stabilizing reinforcement ribs 19 at their respective bends. The stabilizing reinforcement ribs 19 are preferably processed into an isosceles triangle plate structure to improve the shaping strength of the bracket's bending surface and ensure the stable position relationship of the electrical accessories.

[0039] As specific implementation details, such as Figure 14As shown, the lower bent parts of the two opposing copper busbar brackets 4 are connected by two parallel and spaced-apart beams 5. The cross section of the beam 5 is a Γ-shaped hook structure. Several wire holes are provided along the length of the beam 5, and a strip-shaped pressing groove 18 is provided in parallel with the line of wire holes. The strip-shaped pressing groove 18 is extruded upward. The design of this beam 5 serves as a panel to support the module and improves the bending resistance of the beam 5. In practice, when used as a wire baffle, the flat surface and the arc surfaces on both sides are used to constrain the cable routing position. The aforementioned wire holes are used to bundle and constrain cables, and the large flat surface at the bottom of the beam 5 is mainly used to support and constrain the module distribution circuit breaker. In addition, similar to the aforementioned copper busbar bracket 4, the beam 5 is stamped with reinforcing ribs to improve the structural stability of the beam 5 and strengthen and balance the bending resistance of the beam 5. A pair of fixing plates 6 are arranged above and in parallel between the two beams 5, and the two ends of the fixing plates 6 are respectively fixed to the upper bent part of the copper hollowing bracket 4, and a groove with a structure consistent with the strip-shaped pressing groove 18 is opened along the length direction of the fixing plates 6, so that the metal frame structure is more solid and can provide more installation and bearing parts for use.

[0040] Finally, another embodiment of the present invention also provides a power distribution control cabinet, which includes a cabinet body, in which any one of the integrated power distribution input and output modules described in the above embodiments is installed. For the specific structure of the cabinet body, technical personnel in this field can adapt the design or directly adopt some existing control cabinets for combined installation.

[0041] 1. The present invention standardizes the power distribution module, decouples the power distribution and the cabinet, changes the existing product serial production mode, greatly improves production efficiency; reduces packaging and transportation costs; and changes the project site installation and deployment mode, making on-site installation and deployment simple and flexible without relying on handling equipment.

[0042] 2. The product of the present invention is flexible in form and adopts a modular and integrated structure, which changes the situation in which existing products, regardless of size, need to occupy the entire cabinet. Users can choose one or more modules to use in combination according to the scale of demand. In most cases, it can save about half of the cabinet space compared with existing products, reducing user costs.

[0043] 3. The present invention is a standardized module that supports uninterrupted maintenance and uninterrupted expansion, which changes the problem that existing products require long power outages for maintenance. Users can flexibly expand the power distribution circuit as their business grows, significantly improving product availability and maintainability and ensuring power supply continuity.

[0044] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention and are not limiting. Although the present invention has been described in detail with reference to the preferred embodiments, those skilled in the art should understand that the technical solutions of the present invention may be modified or replaced by equivalents without departing from the purpose and scope of the technical solutions of the present invention, which should all be included in the scope of the claims of the present invention.
