Description

Technical Field

[0001] This utility model relates to the field of power equipment technology, and specifically to an intelligent fusion terminal based on the phase-openable capacity of power distribution stations. Background Technology

[0002] Intelligent converged terminals are core intelligent devices on the distribution network transformer substation side, responsible for collecting substation load data, monitoring power quality, and managing and controlling the access of distributed energy sources. They are key to realizing intelligent and lean management of the distribution network. With the development of the social economy, user electricity load is constantly increasing, especially the random access of single-phase large-capacity loads, which often leads to three-phase imbalance or excessive load on one phase in the transformer substation, directly affecting power supply reliability and power quality.

[0003] To address this issue, the common approach is to expand the existing distribution area by adding new outgoing circuits or installing new terminal equipment. However, the internal structure of existing smart converged terminals is usually fixed. When expansion is required, the following technical challenges are often encountered: 1. Inconvenient expansion: The addition of new expansion terminals (or functional modules) requires additional installation space, while the internal space of the standard terminal box is limited and the layout is fixed, making it difficult to flexibly add and fix new equipment.

[0004] 2. Complex connection: The electrical connection between the expansion equipment and the main terminal usually requires cumbersome operations such as stripping wires, splicing, and insulation treatment on site. This not only results in low installation efficiency but also easily introduces safety hazards such as wiring errors or poor contact.

[0005] 3. Poor flexibility: Existing installation methods cannot be flexibly adjusted according to the number and size of expansion modules, lacking an adjustable and scalable universal installation architecture. Each expansion may require custom-made installation accessories, or even replacement of the entire enclosure, resulting in high expansion costs and long cycles.

[0006] 4. Impact on power supply: The complex installation and wiring process often requires power outages in the existing transformer area, affecting users' normal power supply.

[0007] Therefore, there is an urgent need in this field for a new type of intelligent converged terminal that can solve the above problems, realize rapid, flexible, safe and uninterrupted modular capacity expansion, thereby efficiently balancing the three-phase load of the distribution area and improving the overall power supply capacity and service quality of the distribution area.

[0010] Furthermore, the expansion support assembly includes at least two fixing plates and at least one connecting rod connected therebetween; A joint is rotatably mounted on the middle of the fixed plate via a pivot, and the joint is hinged to one end of the connecting rod.

[0011] Furthermore, the connecting rod is a hollow cylindrical structure with a pull rod slidingly installed inside.

[0015] Furthermore, a locking bolt is also provided inside the cylinder, with one end of the locking bolt in contact with the ball bearing to restrict the movement of the ball bearing.

[0016] Furthermore, the side wall of the connecting rod is provided with an arc-shaped groove that matches the ball bearing, and the ball bearing slides in contact with the arc-shaped groove under the elastic force of the spring.

[0017] Furthermore, multiple locking screw holes are evenly provided on the side wall of the connecting rod along its axial direction, and the connecting rod is fixed to the locking screw holes by screws.

[0018] The beneficial effects of this utility model are: 1. High efficiency in space utilization: Through the adjustable design of the expansion bracket group, one or more expansion modules can be flexibly arranged in the limited electrical installation cavity 11, which greatly improves the space utilization rate and avoids the need to replace the entire enclosure.

[0024] In the description of this application, it should be noted that the terminology used herein is for the purpose of describing particular embodiments only and is not intended to limit the exemplary embodiments according to this application. For ease of description, the dimensions of the various parts shown in the drawings are not drawn to actual scale.

Therefore, other examples of exemplary embodiments may have different values. It should be noted that similar reference numerals and letters in the following drawings denote similar items; therefore, once an item is defined in one drawing, it need not be further discussed in subsequent drawings.

[0025] Please see Figures 1 to 6 This utility model provides an intelligent converged terminal with adjustable capacity based on phased distribution, including a housing 10, with an electrical mounting cavity 11 inside. A main distribution area control terminal 20 and a wiring terminal 30 are disposed on the side wall of the electrical mounting cavity 11, with the wiring terminal 30 electrically connected to the main distribution area control terminal 20. An expansion bracket assembly 40 is disposed between the two side walls of the electrical mounting cavity 11. A fixing component 50 is mounted on the expansion bracket assembly 40. An expansion distribution area control terminal 60 is disposed on the fixing component 50 and electrically connected to the main distribution area control terminal 20 via the wiring terminal 30. By combining the adjustable expansion bracket assembly 40 with the modular fixing component 50, rapid installation, precise positioning, and reliable electrical connection of the expansion distribution area control terminal 60 are achieved. This solves the problems of difficult capacity expansion, cumbersome wiring, poor flexibility, and the need for power outages associated with traditional fixed terminals. Example 1

[0026] See Figure 1 and Figure 2This embodiment focuses on describing the basic structure of the intelligent converged terminal and the establishment of the expansion installation architecture. The enclosure 10 serves as the protective shell for the entire device, and its internal electrical mounting cavity 11 houses all electrical components. The main control unit 20 is the core processing unit of the terminal, responsible for data acquisition, communication, calculation, and control. Terminal blocks 30 are located next to the main control unit 20 and are pre-connected to the internal circuitry of the main control unit 20, providing standardized electrical interfaces (such as plug-in terminal blocks) for quick connection to the expansion control unit 60. The expansion bracket assembly 40 serves as a key support structure, with both ends fixed to the screw holes 12 on the side walls of the electrical mounting cavity 11 using screws. The fixing assembly 50 is installed on the expansion bracket assembly 40 to ultimately support the expansion control unit 60.

[0027] The technical advantages of this solution are as follows: Firstly, the integration of the main control terminal 20 and the wiring terminal 30 provides pre-prepared, standardized electrical connection points for capacity expansion, avoiding potential safety and quality hazards associated with on-site wiring. Secondly, the pre-installed, regularly distributed screw holes 12 on the side wall of the enclosure provide high flexibility for the installation of the expansion bracket assembly 40. The most suitable installation location can be selected based on the actual space and the size of the expansion module, laying a physical foundation for subsequent flexible expansion. The expansion bracket assembly 40 spans between the two side walls, forming an independent and robust mounting plane, separating the installation of the expansion equipment from the main equipment, ensuring no interference and a clear structural design. Example 2

[0028] See Figure 3 , Figure 4 and Figure 6 This embodiment details the specific structure of the expansion bracket assembly 40 and the resulting adjustability. The expansion bracket assembly 40 includes at least two fixing plates 41 and at least one connecting rod 43 connected therebetween. The fixing plates 41 are fixedly connected to the screw holes 12 on the side wall of the electrical mounting cavity 11 by screws, thereby anchoring the entire bracket assembly inside the housing. Each fixing plate 41 has a connector 42 rotatably mounted in the middle via a pivot. The connector 42 is hinged to one end of the connecting rod 43.

[0029] Preferably, the connecting rod 43 is a hollow cylindrical structure, and another tie rod 45 is slidably disposed inside it. The end of the tie rod 45 away from the connecting rod 43 is also hinged to another joint 42, which is rotatably connected to another fixed plate 41.

[0030] Furthermore, multiple locking screw holes 44 are evenly provided along the axial direction on the side wall of the connecting rod 43. After the length of the entire bracket is adjusted by sliding the tie rod 45, screws can be passed through the locking screw holes 44 and tightened against the tie rod 45 inside to fix the length.

[0031] The technical advantages of this solution are as follows: The fixing plate 41 can be installed on screw holes 12 at different heights on the side wall, thereby adjusting the overall installation height of the bracket. The total length of the bracket can be steplessly adjusted by sliding the tie rod 45 within the connecting rod 43 and fixing it with the locking screw hole 44, to accommodate enclosures of different widths or to make room for different numbers of expansion modules. Since the fixing plate 41 and the connector 42 are rotatably connected, and the connector 42 and the connecting rod 43 are hinged, the connecting rod 43 can swing relative to the fixing plate 41 within a certain angle range. When the mounting surfaces of the enclosure side wall are not perfectly parallel or have deviations due to processing errors, this hinged structure can adaptively adjust, ensuring that the bracket is stress-free after installation and that the connecting rod 43 is always reliably straightened and tightened, avoiding installation difficulties or structural deformation problems that may result from rigid connections. Example 3

[0032] See Figure 3 , Figure 4 and Figure 5 This embodiment details how the fixing component 50 achieves rapid installation and reliable locking with the expansion bracket assembly 40.

[0033] The fixing assembly 50 includes an expansion plate 51 on which the expansion platform control terminal 60 is fixedly mounted. A slot 52 is provided on one side of the expansion plate 51. The shape of the slot 52 is adapted to the cross section of the connecting rod 43 of the expansion bracket assembly 40, and is used to directly snap onto the connecting rod 43.

[0034] The expansion plate 51 is also provided with a cylinder 53, in which a ball bearing 54 is embedded. A spring 55 is provided between the ball bearing 54 and the inner bottom wall of the cylinder 53. On the side wall of the connecting rod 43, there is an arc-shaped groove 43a that matches the ball bearing 54. When the slot 52 of the expansion plate 51 is engaged with the connecting rod 43, under the elastic force of the spring 55, the ball bearing 54 is pushed out and embedded in the arc-shaped groove 43a on the connecting rod 43.

[0035] Preferably, a locking bolt 56 is also provided inside the cylinder 53. The upper end of the locking bolt 56 is preferably provided with a handle for the operator to rotate manually. The operator can tighten the locking bolt 56, and its end can press down against the ball 54 to increase the pressure of the ball 54 on the arc-shaped groove 43a until it is completely locked to prevent it from loosening in a vibrating environment.

[0036] The technical advantages of this solution are as follows: The design of the fixing component 50 achieves "slide-in and lock-in" for the expansion module. During installation, simply align the slot 52 with the connecting rod 43 and gently push it in; the ball bearing 54 will automatically fall into the groove under the action of the spring, completing the initial positioning and fixing. The installation process is extremely quick and requires no tools. The cooperation between the ball bearing 54 and the arc-shaped groove 43a forms an effective mechanical limit, preventing the expansion plate 51 from detaching from the connecting rod 43 in the vertical direction. At the same time, the spring 55 structure has a certain shock absorption and buffering effect, improving the reliability of the equipment during operation.

[0037] Meanwhile, the locking bolt 56 provides a second layer of security. After initial insertion, operators can use tools to tighten the locking bolt 56 to achieve final, absolute fastening, meeting the high requirements of power equipment for long-term operational stability. This design balances ease of installation with operational reliability. Example 4

[0038] This embodiment, combining all the above components, describes the overall workflow for capacity expansion of a distribution area, as follows: 1. Planning and Preparation: Based on the increased load demand in the transformer area, determine the quantity and specifications of the additional transformer area control terminals 60 that need to be added. Take out the corresponding number of expansion bracket sets 40, fixing components 50, and expansion terminals 60 from the inventory.

[0039] 2. Mounting the Bracket: Based on the remaining space inside the enclosure 10 and the dimensions of the expansion terminal 60, select a suitable height for the screw holes 12 on the side wall of the electrical mounting cavity 11. Initially fix the fixing plate 41 to the screw holes 12 on one side wall using screws. Then, adjust the lengths of the connecting rod 43 and the pull rod 45, aligning and fixing the fixing plate 41 at the other end with the screw holes 12 on the other side wall. During adjustment, the hinge joint 42 adapts to the angle to ensure smooth installation. Finally, use screws to screw into the locking screw holes 44 to lock the relative positions of the pull rod 45 and the connecting rod 43.

[0040] 3. Install the fixing components and terminal: Pre-install the expansion plate 51 with screws on the expansion area control terminal 60. Then, align the slot 52 of the expansion plate 51 with the installed connecting rod 43 and push it in horizontally until you hear a "click" sound as the ball bearing 54 falls into the arc-shaped groove 43a. Subsequently, manually rotate the handle of the locking bolt 56 or use an Allen wrench or other tools to tighten the locking bolt 56 to completely lock the expansion plate 51 onto the connecting rod 43.

[0041] 4. Electrical Connection: Insert the connecting cable (with a pre-made plug at the end) provided with the expansion control terminal 60 into the corresponding interface on the terminal block 30 next to the main control terminal 20. The terminal block 30 is designed to prevent mis-insertion, ensuring correct connection.

[0042] 5. Commissioning and Operation: After completing the installation and wiring of all expansion terminals, close the cabinet door, power on, and perform system commissioning. The main control terminal 20 will automatically identify the newly connected expansion terminals and coordinate load allocation and management.

[0043] The technical advantages of this solution are as follows: Standardized process: The entire process is clear and simple to operate, which greatly reduces the technical requirements for on-site construction personnel and reduces human error.

[0044] Significantly improved efficiency: Traditional capacity expansion methods can take several hours and require power outages. This solution, however, can complete the installation of an expansion module without power interruption, significantly improving power supply reliability and user satisfaction.

[0045] High safety and reliability: All electrical connections are completed through prefabricated interfaces, with no exposed wires, good insulation, and high safety. Mechanical connections are secured by a double locking mechanism, ensuring stable equipment operation.

[0046] The entire system can add or remove "loads" (expansion terminals) as needed at any time, realizing on-demand and flexible expansion of distribution area capacity, which perfectly matches the development direction of intelligent distribution network.

[0047] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
