Description

Technical Field

[0001] This application relates to the technical field of smart grids, and in particular to a standardized smart compensation distribution box. Background Technology

[0002] In the smart grid system, the reactive power compensation control box is an integrated power electronic device whose core function is to compensate for reactive power in the power system. This device relies on intelligent control strategies to dynamically adjust the reactive power conditions of the power grid, effectively improving the power factor, suppressing voltage fluctuations and harmonic interference, and comprehensively optimizing overall power quality. Currently, this type of equipment is widely deployed in distribution substations, often used in conjunction with transformers. It is a key facility for reducing distribution network losses and increasing efficiency, and ensuring power supply stability. Its application is mainly outdoor pole-mounted installation, operating in an open environment for extended periods, thus requiring high structural reliability and ease of maintenance.

[0003] Existing reactive power compensation distribution boxes mainly consist of a box body, multiple doors, and internal electrical components. The doors are mounted on the front and rear sides of the box body and can be opened and closed flexibly. The core electrical components inside the box body include capacitor banks and an intelligent controller. The capacitor banks are connected in parallel to achieve reactive power compensation. The controller can collect grid signals and receive external commands to automatically control the switching of the capacitor banks, completing dynamic reactive power compensation. During installation, the box body is fixed to a pre-laid cement base on the ground using bolts.

[0004] Among the aforementioned technologies, existing reactive power compensation distribution boxes are suitable for conventional environments but are ill-suited for the rainy and humid conditions of the southern coastal regions. The top of these boxes is flat, making it easy for rainwater to accumulate and accumulate during rainy weather, hindering rapid drainage and causing continuous water seepage onto the top surface. Furthermore, the multi-door, split-type structure allows accumulated rainwater to easily seep into the box through the gaps between the box body and doors, causing internal electrical components to become damp, reducing insulation performance, and potentially leading to short circuits, equipment malfunctions, and shutdowns. Therefore, there is room for improvement. Summary of the Invention

[0005] The purpose of this application is to provide a standardized intelligent compensation distribution box to solve the problems of water accumulation on the top of existing distribution boxes and water seepage through the gaps in the box doors, which leads to moisture damage to internal electrical components and poor equipment operation stability.

[0006] The standardized intelligent compensation distribution box provided in this application adopts the following technical solution: A standardized intelligent compensation distribution box includes a box body, a door rotatably mounted on the front and rear sides of the box body, and a cover fixed to the top surface of the box body. The left and right sides of the box body have ventilation openings and wiring ports. The front and rear edges of the cover protrude from the front and rear sides of the box body and provide protection for the top surface of the door when closed. A clearance is pre-set between the bottom surface of the protruding part of the cover and the top surface of the door when closed. A guide slope is provided at both the front and rear edges of the top surface of the cover, and a locking element is provided on the outside of the box body. Protective plates are provided on both the front and rear sides of the cover, horizontally engaged within the clearance and fixed by the locking element. A guide slope is provided on the top surface of the protective plate away from the edge of the cover. The protective plates further protect the cover when closed, and the guide slope and the guide slope work together to allow rainwater to flow quickly and slide off.

[0007] By adopting the above technical solution, the protruding structure of the enclosure cover can block the gap at the top of the enclosure door, preventing rainwater from directly seeping into the connection gap between the enclosure and the door, thus reducing the risk of water seepage at the source. Simultaneously, the guide slope and the guide slope of the protective plate work together to form a continuous and smooth water-guiding slope, allowing rainwater on the top of the enclosure to be quickly guided and discharged to the sides and outside during rainy weather, preventing rainwater from accumulating and soaking the equipment shell for extended periods. Compared to traditional flat enclosure top structures, this composite water-guiding and protective structure is suitable for the rainy and humid conditions of the southern coastal areas, significantly improving the outdoor waterproof performance of the equipment. It effectively prevents problems such as moisture damage to internal electrical components, insulation failure, and short circuits caused by rainwater seepage, ensuring the stable operation of the intelligent compensation components, extending the service life of the equipment, and improving the power supply stability of the distribution area.

[0008] Optionally, the exterior of the enclosure is equipped with fasteners, and the locking mechanism includes elastic locking rods that are rotatably mounted on the left and right sides and have elastic shortening properties. The other end of the elastic locking rods is rotatably connected to the left and right sides of the protective plate. Two locking blocks are fixed on the vertical inner wall of the clearance gap. The protective plate has an installation notch on the side facing the enclosure, and an installation rod is detachably installed inside the installation notch. The installation rod has a locking slot. The two elastic locking rods on the same vertical side of the enclosure can rotate towards each other to a vertically upward retracted state and be fixed by the fasteners, and rotate away from each other to a horizontal locking state. When the elastic locking rods are in the locked state, the protective plate is in a horizontal protective state located in the clearance gap, and the locking blocks are engaged in the locking slots. When the elastic locking rods are in the retracted state, the protective plate rotates to a horizontal retracted state located above the enclosure lid, and the guide slope abuts against the flow guide slope.

[0009] By adopting the above technical solution, the elastic locking lever can be rotated to switch between horizontal locking and vertical storage states as needed. The structure adjustment is simple and convenient, requiring no additional auxiliary tools. Utilizing its elastic telescopic characteristics, the locking block can elastically engage with the locking slot, achieving precise positioning and locking of the protective plate. In the protective state, the structure fits tightly and is firmly fixed, preventing the protective plate from loosening or shifting in outdoor wind and rain conditions. In the storage state, it can be quickly unlocked and used with fasteners to fold the protective plate, reducing the overall space occupied by the equipment. This balances the stability of equipment operation and protection with the convenience of transportation and storage, making it suitable for engineering installation and relocation scenarios.

[0010] Optionally, the fixing component includes an elastic fixing rod rotatably mounted on the left and right sides and having elastic shortening properties. A middle rod is vertically fixed at both ends of the elastic fixing rod, and a fixing protrusion is rotatably connected to the end face of the middle rod away from the elastic fixing rod. A first slot is provided on the guide slope of the cover. When the protective plate is in the protective state, a second slot is vertically provided at the outer edge of the bottom surface, and a limiting slot is provided at the outer edge of the bottom surface. When the protective plate is in the horizontally retracted state, the elastic fixing rod rotates to a vertically upward state, the fixing protrusion rotates to a vertically downward state and inserts into the first slot, and the outer side of the middle rod abuts against the side of the protective plate facing the door at this time. When the protective plate is in the horizontal protective state, the elastic fixing rod rotates to an inclined upward state along the direction close to the door, the fixing protrusion rotates to a vertically upward state and inserts into the second slot, and the middle rod is engaged in the limiting slot.

[0011] By adopting the above technical solution, in the case of the protective plate being stored, the fixing protrusion is inserted into the first slot, and the side of the middle rod abuts against the limit, firmly locking the protective plate in its folded state and preventing structural loosening and shaking during transportation. In the case of the protective plate being in operation, the fixing protrusion is inserted into the second slot, and the middle rod is engaged in the limit slot. This not only strengthens the support stability of the protective plate and improves the overall rigidity of the equipment's waterproof protection structure, but also limits the opening angle of the cabinet door by relying on the rotation stroke of the elastic fixing rod, avoiding structural collisions and cable pulling caused by excessive opening and closing of the cabinet door. This multi-functional design simplifies the overall structure of the equipment and reduces production and maintenance costs.

[0012] Optionally, a first inclined surface is provided at the outer edge of the end of the fixed protrusion away from the intermediate rod.

[0013] By adopting the above technical solution, the first inclined surface has a guiding chamfer function, which can effectively offset the assembly alignment deviation. During the process of inserting the fixed protrusion into the first slot and the second slot, it can autonomously guide the protrusion to accurately align and insert, avoiding jamming and incomplete insertion caused by processing errors and assembly offsets, and greatly reducing the difficulty of manual assembly and working condition switching.

[0014] Optionally, when the protective plate is in a horizontal protective state, a positioning groove is provided on the bottom surface. The positioning groove has a positioning notch on the side facing the box that communicates with the installation notch. A first slot is provided on the inner wall of the installation notch. When the protective plate is in a horizontal protective state, a positioning plate is rotatably installed on the positioning groove away from the edge of the box. The positioning plate is in a horizontal state and placed in the positioning groove. An elastic positioning rod is fixed on the side facing the box, which is placed in the positioning notch, detachably connected to the lower end face of the mounting rod, and has elastic shortening performance. An installation block is fixed on the mounting rod that is engaged in the first slot.

[0015] By adopting the above technical solution, during normal operation, the positioning plate is completely housed within the positioning groove, with no protruding structures, thus not affecting the equipment's airflow protection effect or overall appearance flatness. The elastic positioning rod, relying on its elastic extension and contraction properties, drives the mounting block to stably engage in the first slot, achieving detachable locking and positioning of the mounting rod. The structure is tightly fitted, with strong resistance to wind, rain, and vibration, preventing the mounting rod from loosening and falling off during outdoor operation. Simultaneously, the embedded storage design does not occupy external space, has a compact structure, and is easy to assemble and disassemble, facilitating future equipment maintenance and parts replacement, thus improving the ease of equipment operation and maintenance.

[0016] Optionally, when the two protective plates are in a horizontally retracted state, a second slot is provided on the side facing each other, and the elastic positioning rod is rotatably connected to the mounting rod; a positioning groove is provided on the top wall of the protective plate when it is in a horizontal protective state, and a movable wheel placed in the accommodating groove is fixed on the top surface of the positioning plate at this time; when the protective plate is in a horizontally retracted state, the positioning plate rotates out of the positioning groove and flips to a horizontal state, the mounting rod rotates to a vertically downward state at this time, the mounting block is inserted into the second slot at this time, and finally the entire box is flipped so that the movable wheel faces the ground.

[0017] By adopting the above technical solution, during equipment transportation and storage, the flip-up positioning plate allows the mounting clips to engage with the second slot of the opposite protective plate, locking the positioning plate in place. The exposed casters support the entire equipment, enabling rapid short-distance transport and relocation through rolling friction, eliminating the need for manual lifting and significantly reducing labor intensity during transport. During normal operation, the casters are completely retracted into the receiving trough, with no exposed protrusions, ensuring no impact on the equipment's waterproof protection structure or installation fixation. This structure balances the needs of equipment storage and transportation with on-site relocation, offering high structural reusability and effectively improving the convenience and efficiency of equipment installation and construction.

[0018] Optionally, a second bevel is provided on the outer edge of the side of the mounting block away from the mounting rod.

[0019] By adopting the above technical solution, the second inclined surface can play a guiding and transitioning role in the process of the installation block being inserted into the first and second slots, reducing the resistance of the snap-fit ​​assembly, realizing rapid alignment and snap-fit, eliminating the need for manual forceful pressing and correction, and simplifying the assembly operation process.

[0020] Optionally, a third inclined surface is provided at the front and rear edges of the bottom surface of the box cover.

[0021] By adopting the above technical solution, the third inclined surface forms an inclined transition surface, which can effectively avoid the hard impact interference of the protective plate flipping, ensure the smooth movement of each structure, and avoid wear and deformation of parts.

[0022] Optionally, the housing is fixed with a downward-facing airflow guide at the outer edge of the heat dissipation vent opening.

[0023] By adopting the above technical solution, the downward-opening air guide can form a shielding barrier, effectively preventing rainwater from seeping into the housing through the heat dissipation vents, while also blocking outdoor dust and debris from flying into the interior, thus protecting the internal electrical components.

[0024] Optionally, the housing is fixed with a downward-bent protective tube at the outer edge of the wiring port opening.

[0025] By adopting the above technical solution, the connection port is a critical gap for line access and also a weak point for water seepage and dust accumulation. The downward-bent protective tube can completely cover the connection port and the cable connection part to form a closed protective structure.

[0026] In summary, this application includes the following beneficial technical effects: In this application, the protruding structure of the cover can block the gap at the top of the door, preventing rainwater from directly seeping into the connection gap between the box body and the door, thus reducing the risk of water leakage at the source. At the same time, the guide slope and the guide slope of the protective plate are connected and cooperate with each other to form a continuous and smooth water guiding slope. In rainy weather, rainwater on the top surface of the box can be quickly guided and discharged to the sides and the outside, avoiding rainwater retention and accumulation and long-term soaking of the equipment shell.

[0029] The present application will be further described in detail below with reference to all the accompanying drawings.

[0030] Example: Reference Figure 1 and Figure 2A standardized intelligent compensation distribution box includes a box body 1, several box doors 2 rotatably installed on the front and rear sides of the box body 1, and a box cover 3 fixed on the top surface of the box body 1. Heat dissipation vents 11 and wiring ports 12 are provided on the left and right sides of the box body 1. A downward-facing guide shroud 13 is fixed at the outer edge of the opening of the heat dissipation vent 11, and a downward-bent protective tube 14 is fixed at the outer edge of the opening of the wiring port 12. The front and rear edges of the cover 3 protrude from the front and rear sides of the box body 1 and protect the top surface of the box door 2 when it is closed. The front and rear edges of the top surface of the cover 3 are provided with guide slopes 31. When the distribution box is installed and used, the box body 1 is fixed to the cement base platform laid on the ground with bolts. On rainy days, the guide slopes 31 are used to quickly guide the rainwater on the top surface of the cover 3 to slide down.

[0031] Reference Figure 3 and Figure 4 A clearance is pre-set between the bottom surface of the protruding part of the box cover 3 and the top surface of the box door 2 when it is closed. A locking element 5 is provided on the outside of the box body 1. A protective component 4 is provided on both the front and rear sides of the box cover 3. The protective component 4 includes a protective plate 41 that is horizontally engaged in the clearance and fixed by the locking element 5. A guide slope 411 is provided on the top surface of the protective plate 41 away from the edge of the box cover 3. When the distribution box is installed and applied, the protective plate 41 is used to further protect the box cover 3 when it is closed. Then, the guide slope 31 and the guide slope 411 cooperate with each other to allow rainwater to flow down quickly during rainy days.

[0032] Reference Figure 4 , Figure 5 and Figure 6 The outer side of the housing 1 is provided with a fixing member 6, and the locking member 5 includes an elastic locking rod 51 that is rotatably mounted on the left and right sides and has elastic shortening performance. The other end of the elastic locking rod 51 is rotatably connected to the left and right sides of the protective plate 41. Two locking blocks 15 are fixed on the vertical inner wall of the clearance gap. The protective plate 41 has an installation notch 412 on the side facing the housing 1. An installation rod 42 is detachably installed inside the installation notch 412. A locking slot 421 is provided on the installation rod 42. The two elastic locking rods 51 on the vertical side of the same housing 1 can rotate to a vertically upward storage state facing each other and to a horizontal locking state facing away from each other. During the transportation of the distribution box, the elastic locking rod 51 is pre-adjusted to the locked state, and the protective plate 41 is then rotated to a horizontal protective state located in the clearance gap. The locking block 15 is then elastically inserted into the locking slot 421 by utilizing the elastic shortening performance of the elastic locking rod 51. When the elastic locking rod 51 is pre-adjusted to the retracted state during the transportation of the distribution box, the protective plate 41 is rotated to a horizontal retracted state located above the box cover 3 and fixed by the fastener 6. The guide slope 411 then abuts against the flow guiding slope 31, reducing the transportation volume occupied by the distribution box in this state and reducing transportation costs.

[0033] Reference Figure 7 , Figure 8 and Figure 9 The fixing member 6 includes an elastic fixing rod 61 that is rotatably mounted on the left and right sides and has elastic shortening properties. The two ends of the elastic fixing rod 61 are vertically fixed with a middle rod 62. A fixing protrusion 63 is rotatably connected to the end face of the middle rod 62 away from the elastic fixing rod 61. A first inclined surface 631 is provided at the outer edge of the end of the fixing protrusion 63 away from the middle rod 62. A first slot 32 is provided on the guide inclined surface 31 on the box cover 3. When the protective plate 41 is in the protective state, a second slot 413 is provided in the vertical direction at the edge away from the box body 1, and a limit slot 417 is provided at the outer edge of the bottom surface. When the protective plate 41 is in a horizontal storage state (i.e., when the distribution box is being transported), the elastic fixing rod 61 rotates to a vertical upward state, and the fixing protrusion 63 rotates to a vertical downward state and is inserted into the first slot 32. The cross-section of the first slot 32 is larger than the cross-section of the fixing protrusion 63 so that the fixing protrusion 63 can be smoothly inserted into the first slot 32. The outer side of the middle rod 62 abuts against the side of the protective plate 41 facing the box door 2 at this time, thereby limiting and locking the state of the protective plate 41 at this time. When the protective plate 41 is in a horizontal protective state (i.e., in the application of the distribution box), the elastic fixing rod 61 rotates to an inclined upward state along the direction close to the box door 2, the fixing protrusion 63 rotates to a vertical upward state and inserts into the second slot 413, and the middle rod 62 is inserted into the limiting slot 417. In this way, the elastic fixing rod 61 is used to further tilt and support the protective plate 41 in this state, and the elastic fixing rod 61 is used to limit the opening angle of the box door 2 to prevent the box door 2 from being opened too much.

[0034] Reference Figure 10 , Figure 11 and Figure 12 When the protective plate 41 is in a horizontal protective state, a positioning groove 414 is provided on the bottom surface. The positioning groove 414 is provided with a positioning notch 415 communicating with the installation notch 412 on the side facing the box 1. A first slot 4121 is provided on the inner wall of the installation notch 412. When the protective plate 41 is in a horizontal protective state, a positioning plate 43 is rotatably installed on the edge away from the box 1. The positioning plate 43 is provided with an elastic positioning rod 44 fixed on the side facing the box 1, which is placed in the positioning notch 415, detachably connected to the lower end face of the mounting rod 42, and has elastic shortening performance. A mounting block 45 is fixed on the mounting rod 42. The mounting block 45 has a second inclined surface 451 on the outer edge of its side away from the mounting rod 42, and a third inclined surface 33 is provided on the front and rear edges of the bottom surface of the box cover 3. When the protective plate 41 is in a horizontal protective state, the positioning plate 43 is in a horizontal state and is placed in the positioning groove 414, the elastic positioning rod 44 is in the positioning notch 415, the mounting rod 42 is placed in the mounting notch 412, and the mounting block 45 is elastically engaged in the first slot 4121.

[0035] Reference Figure 12 and Figure 13 When the two protective plates 41 are in a horizontal storage state, a second slot 416 is provided on the side that is close to each other. The elastic positioning rod 44 is rotatably connected to the mounting rod 42. The positioning groove 414 is provided on the top wall of the protective plate 41 when it is in a horizontal protective state. The positioning plate 43 is fixed on the top surface at this time with a moving wheel 46 placed in the accommodating groove 4141. When the protective plate 41 is in a horizontal protective state, the moving wheel 46 is stored in the receiving trough 4141; when the protective plate 41 is in a horizontal stored state, the positioning plate 43 rotates out from the positioning trough 414 and flips to a horizontal state, the mounting rod 42 rotates to a vertical downward state, the mounting block 45 is inserted into the second slot 416, and then the entire distribution box is flipped to a state where the moving wheel 46 faces the ground. At this time, the distribution box can be moved quickly and short distances by means of the rolling friction between the moving wheel 46 and the ground.

[0036] The implementation principle of this application embodiment is as follows: When the equipment is in protective operation, the elastic locking rods 51 on both sides of the housing 1 are rotated to a horizontal locking position, causing the front and rear protective plates 41 to horizontally engage in the clearance between the housing cover 3 and the housing door 2. Utilizing the elastic shortening characteristic of the elastic locking rods 51, the locking block 15 elastically engages in the locking slot 421, completing the positioning and fixing of the protective plate 41. Simultaneously, the elastic fixing rod 61 is rotated to an upward tilting position, allowing the fixing protrusion 63 to insert into the second slot 413, with the top surface of the middle rod 62 adhering to the bottom surface of the protective plate 41, providing auxiliary support for the protective plate 41 and limiting the opening angle of the housing door 2. At the same time, the positioning plate 43 is housed in the positioning recess 414 of the protective plate 41, and the elastic positioning rod 44, in conjunction with the installation block 45, engages in the first slot 4121 of the installation notch 412, locking the position of the installation rod 42. At this time, the guiding slope 411 of the protective plate 41 and the flow guiding slope 31 of the housing cover 3 cooperate to form a complete water guiding structure, with all structures of the equipment interlocked, maintaining stable protective operation.

[0037] When the equipment is in the transport and storage state, first adjust the elastic locking rod 51 to the vertically upward storage state to release the lock on the protective plate 41. Flip the protective plate 41 to the horizontal storage position above the box cover 3, so that the guide slope 411 is tightly attached to the guide slope 31 of the box cover 3. Rotate the elastic fixing rod 61 to the vertically upward state, so that the fixing protrusion 63 is inserted into the first slot 32 to limit and fix the protective plate 41 in the storage state. Then flip the positioning plate 43 so that it rotates out of the positioning groove 414, driving the mounting rod 42 to the vertically downward. Through the mounting block 45, it is locked into the second slot 416 of the other protective plate 41, locking the overall state of the positioning plate 43. At this time, the moving wheels 46 on the top surface of the positioning plate 43 are exposed inside and outside the groove 4141. Flip the entire distribution box so that the moving wheels 46 contact the ground. Relying on the rolling contact, the equipment can be moved quickly over a short distance. The overall structure is completely folded up, adapting to the transport and storage conditions.
