Description

Technical Field

[0001] This invention relates to the field of integrated primary and secondary ring network box technology, specifically a high-reliability integrated primary and secondary ring network box. Background Technology

[0002] In the context of power system upgrades towards smart distribution networks, traditional ring main units (RMS) suffer from limitations due to the separate deployment of primary equipment (such as circuit breakers, busbars, and disconnectors) and secondary equipment (such as measurement and control modules, protection devices, and data acquisition units). These are connected by complex cables, resulting in low integration, large space requirements, and data exchange delays due to signal transmission losses, affecting measurement accuracy and protection response speed. This makes it difficult to meet the demands of modern power supply for efficient operation and precise control. To address this, integrated primary and secondary RMS systems have emerged. Through integrated design, they deeply integrate the electrical functions of primary equipment with the monitoring, protection, and control functions of secondary equipment. At the hardware level, this achieves a compact layout, reducing cable connections. At the functional level, it optimizes traditional measurement and acquisition processes, improving data transmission efficiency while enhancing fault diagnosis and self-healing capabilities. This allows for rapid location of line anomalies and triggering of protection mechanisms, significantly improving the overall operational stability and intelligence level of the RMS.

[0003] In arid northern regions and high-altitude mountainous areas with large diurnal temperature variations, the outdoor environment is characterized by intense daytime heat and sudden nighttime cooling, with temperature fluctuations exceeding 10°C within hours. This poses a significant challenge to outdoor integrated primary and secondary ring main units. The metal enclosure (mostly stainless steel or aluminum alloy) of these ring main units exhibits different temperature changes compared to the internal air: during the day, the enclosure heats up along with the outside air, resulting in unsaturated moisture. At night, the enclosure cools rapidly due to the high thermal conductivity of metal, causing the inner walls to cool as well. However, the internal air cools later due to the sealed enclosure, dense components, and residual heat, creating an asynchronous temperature state between the low inner walls and the high air temperature. When the inner wall temperature falls below the air dew point, moisture inside the enclosure condenses on its surface, and the sealed design restricts moisture escape, further exacerbating condensation buildup. Condensation easily adheres to secondary components and cable joints, leading to decreased insulation performance and component corrosion, severely impacting the operational reliability of integrated primary and secondary ring main units and becoming a typical hidden danger for equipment operation in such areas. Summary of the Invention

[0004] The purpose of this invention is to provide a highly reliable integrated primary and secondary ring network box to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, the present invention provides the following technical solution: a high-reliability primary and secondary fusion ring network box, comprising a box body, a ring network cabinet installed inside the box body, and several ventilation openings surrounding the box body. An installation partition is fixedly installed on the inner wall of the box body near each ventilation opening. An insulation box is fixedly installed on the outside of one side of the installation partition, and a liquid storage tank is fixedly installed on the outside of one side of the insulation box. A heating and decondensation removal assembly is provided inside and outside the insulation box, and a liquid injection and repair assembly is provided outside the liquid storage tank. The heating and decondensation removal assembly includes a thermally conductive copper plate and several heat-dissipating copper fins. The thermally conductive copper plate is horizontally installed inside the bottom of the insulation box, and the several heat-dissipating copper fins are vertically installed at equal intervals inside the top of the insulation box. The insulation box is filled with a phase change material, and a drive cover assembly is provided outside the insulation box near the thermally conductive copper plate.

[0006] Furthermore, one side of each of the several heat dissipation copper fins is attached to the inner wall of the housing, and a first heat insulation cover is fixedly installed on the outside of the housing near each heat dissipation copper fin. The first heat insulation cover is C-shaped in plan view.

[0007] Furthermore, the drive cover assembly includes a second heat insulation cover and a liquid storage pipe. The second heat insulation cover is disposed on the outside of the bottom end of the heat-conducting copper plate near the heat-insulating box, and the liquid storage pipe is fixedly installed on the inner wall of one side of the box.

[0008] Furthermore, a rotating shaft is fixedly installed through the bottom of the second heat insulation cover, and rotating seats are rotatably installed through both ends of the rotating shaft. The bottom end of the rotating seat is fixedly installed outside the heat insulation box. A heat-conducting copper column is fixedly installed through the box wall near the liquid storage pipe. A positioning plate is fixedly installed at the end of the liquid storage pipe away from the heat-conducting copper column. An abutment rod is slidably installed through the middle of the positioning plate. A limit seat is slidably installed through the outside of the abutment rod. The bottom end of the limit seat is fixedly installed outside the heat insulation box.

[0009] Furthermore, a first piston block is fixedly installed at one end of the contact rod inside the liquid storage tube. The first piston block is slidably and sealingly installed inside the liquid storage tube, and the space between the first piston block and the thermally conductive copper column inside the liquid storage tube is filled with a thermally expanding and contracting liquid.

[0010] Furthermore, a limiting rack is fixedly installed at the end of the abutment rod away from the first piston block, and a limiting gear is fixedly installed at the end of the rotating shaft near the limiting rack, with the limiting gear meshing with the limiting rack.

[0011] Furthermore, a sealing ring is fixedly installed on the edge of the insulation box near the second insulation cover, and a return spring is sleeved on the outer side of the section of the contact rod located inside the liquid storage tube. The two ends of the return spring are respectively fixedly installed on the outer side of one side of the first piston block and the outer side of one side of the positioning plate.

[0012] Furthermore, the fluid injection repair assembly includes a fixing frame and a piston cylinder. The fixing frame is fixedly installed on the outside of the mounting partition, and the piston cylinder is fixedly installed inside the fixing frame. A second piston block is slidably and sealed inside the piston cylinder, and a connecting rod is vertically fixed at the top center of the second piston block.

[0013] Furthermore, a connecting frame is fixedly installed at the top of the connecting rod, one end of the connecting frame is fixedly installed on the outside of one side of the abutting rod, and an inlet pipe and an outlet pipe are fixedly installed through the bottom of the piston cylinder. A first one-way valve is fixedly connected inside the inlet pipe near the piston cylinder, and a second one-way valve is fixedly connected inside the outlet pipe near the piston cylinder.

[0014] Furthermore, one end of the inlet pipe is fixedly installed inside the bottom of the storage tank, and an addition pipe is fixedly installed through one side of the top of the storage tank. A sealing cap is threaded onto the top of the addition pipe. One end of the drain pipe is fixedly installed inside the top of the insulation box. An S-shaped pipe is fixedly connected to the end of the drain pipe inside the top of the insulation box. Several nozzles facing the phase change material are fixed at equal intervals on the bottom wall of the S-shaped pipe.

[0015] Compared with the prior art, the beneficial effects of the present invention are:

[0016] 1. By using an insulated box and a heating and decondensation decongestion assembly, this integrated primary and secondary ring main unit can utilize the phase change material filled inside the insulated box to absorb and stably store external radiant heat and residual heat from the operation of the equipment inside the box during the day. At night, the heat is conducted through the heat-conducting copper plate in the heating and decondensation decongestion assembly, and then directionally transferred to the inner wall of the box through several heat dissipation copper fins. At the same time, the first insulation cover covers the other sides of the heat dissipation copper fins to prevent heat from escaping to the air inside the box or to the outside of the box. This forces the heat to act only on the inner wall, preventing the inner wall temperature from dropping below the air dew point, thereby preventing condensation from forming on the surface of secondary components and cable joints. This effectively avoids the hidden dangers of decreased insulation performance and component corrosion, ensuring operational reliability. Meanwhile, by setting up the drive cover assembly, the second heat insulation cover can cover the heat-conducting copper plate at the bottom of the heat insulation box under structural linkage when dissipating heat at night, closing the heat transfer channel at the bottom and preventing the heat stored in the heat insulation box from being lost to the outside cold air through the heat-conducting copper plate. This achieves concentrated heat to the inner wall, further enhancing the anti-condensation effect and meeting the usage needs of areas with large day-night temperature differences.

[0017] 2. By configuring the drive cover assembly and the liquid injection repair assembly, the integrated primary and secondary ring network box, during use, utilizes the reciprocating motion of the contact rod in the drive cover assembly to drive the connecting rod and the second piston block of the liquid injection repair assembly to slide within the piston cylinder. This draws the repair liquid from the storage tank into the piston cylinder through the inlet pipe, then through the outlet pipe to the S-shaped pipe, and finally evenly injects it into the phase change material (PCM) inside the insulation box through several nozzles. This fills the microscopic cracks caused by the long-term diurnal PCM cycle, restores the internal heat conduction pathways of the PCM, and prevents uneven heat storage and heat release discontinuity caused by cracks, thus maintaining the heat storage and release performance of the PCM. Simultaneously, the drive cover assembly closes its bottom at night to prevent heat loss, working synergistically with the liquid injection repair assembly to ensure the PCM provides stable heating support for the inner wall over a long period, preventing condensation problems from recurring, extending the service life of the PCM and the overall equipment, and further improving the long-term operational reliability of the equipment in areas with large diurnal temperature differences.

Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0034] Example 1: Please refer to Figure 1 - Figure 9 A high-reliability primary and secondary integrated ring network box includes a box body 1, a ring network cabinet 2 installed inside the box body 1, and several ventilation openings 3 surrounding the inside of the box body 1. A mounting partition 9 is fixedly installed on the inner wall of the box body 1 near each ventilation opening 3. An insulation box 4 is fixedly installed on the outside of one side of the mounting partition 9. A liquid storage tank 5 is fixedly installed on the outside of one side of the insulation box 4. A heating and decondensation component is provided inside and outside the insulation box 4. The heating and decondensation component includes a heat-conducting copper plate 6 and several heat-dissipating copper fins 7. The heat-conducting copper plate 6 is horizontally installed through the bottom of the insulation box 4. The several heat-dissipating copper fins 7 are vertically installed through the top of the insulation box 4 at equal intervals. The inside of the insulation box 4 is filled with a phase change material. A drive cover assembly is provided on the outside of the insulation box 4 near the heat-conducting copper plate 6.

[0035] Several heat dissipation copper fins 7 are attached to the inner wall of the housing 1 on one side. The housing 1 is covered and fixed with a first heat insulation cover 8 near the outside of each heat dissipation copper fin 7. The first heat insulation cover 8 is C-shaped in plan view.

[0036] The drive cover assembly includes a second heat insulation cover 10 and a liquid storage pipe 15. The second heat insulation cover 10 is located on the outside of the bottom end of the heat insulation box 4 near the heat-conducting copper plate 6, and the liquid storage pipe 15 is fixedly installed on the inner wall of one side of the box body 1.

[0037] A rotating shaft 11 is fixedly installed inside the bottom of the second heat insulation cover 10. Rotating seats 12 are rotatably installed at both ends of the rotating shaft 11. The bottom end of the rotating seat 12 is fixedly installed outside the heat insulation box 4. A heat-conducting copper column 16 is fixedly installed on the wall of the box body 1 near the liquid storage pipe 15. A positioning plate 35 is fixedly installed at the end of the liquid storage pipe 15 away from the heat-conducting copper column 16. A contact rod 19 is slidably installed through the middle of the positioning plate 35. A limit seat 18 is slidably installed through the outside of the contact rod 19. The bottom end of the limit seat 18 is fixedly installed outside the heat insulation box 4.

[0038] The first piston block 17 is fixedly installed at one end of the contact rod 19 inside the liquid storage tube 15. The first piston block 17 is slidably and sealingly installed inside the liquid storage tube 15. The space inside the liquid storage tube 15 between the first piston block 17 and the thermally conductive copper column 16 is filled with a thermally expanding and contracting liquid.

[0039] A limiting rack 20 is fixedly installed at the end of the abutment rod 19 away from the first piston block 17, and a limiting gear 14 is fixedly installed at the end of the rotating shaft 11 near the limiting rack 20. The limiting gear 14 is meshed with the limiting rack 20.

[0040] A sealing ring 13 is fixedly installed on the edge of the insulation box 4 near the second insulation cover 10. A return spring 21 is sleeved on the outside of the section of the contact rod 19 located inside the liquid storage tube 15. The two ends of the return spring 21 are fixedly installed on the outside of one side of the first piston block 17 and the outside of one side of the positioning plate 35, respectively.

[0041] In this embodiment, when this high-reliability integrated primary and secondary ring network cage is used in areas with large day-night temperature differences, its working principle revolves around a purely mechanical linkage logic of efficient heat absorption and storage during the day and directional heat release and insulation at night. The specific process is as follows:

[0042] During the day, the outside temperature rises and solar radiation is strong. Simultaneously, the operation of equipment such as the ring main unit 2 inside the enclosure 1 generates residual heat. At this time, the heat-conducting copper column 16 quickly senses the high temperatures both outside and inside the enclosure and transfers the heat to the thermally expanding liquid inside the storage pipe 15. The thermally expanding liquid expands upon heating, generating a thrust on the slidingly sealed first piston block 17 inside the storage pipe 15, pushing it to move axially along the storage pipe 15. The contact rod 19, fixedly connected to the first piston block 17, moves synchronously, compressing the sleeve on the contact rod during the process. The return spring 21 outside the contact rod 19; because the end of the contact rod 19 away from the first piston block 17 is fixed with a limiting rack 20, and the limiting rack 20 is meshed with the limiting gear 14 fixed on the rotating shaft 11, the movement of the contact rod 19 will drive the limiting gear 14 to rotate around its own axis, thereby driving the rotating shaft 11 fixed with the limiting gear 14 to rotate synchronously, and finally causing the second heat insulation cover 10 to rotate around the rotating shaft 11 in a direction away from the bottom of the heat insulation box 4, until it is fully opened and the heat-conducting copper plate 6 installed through the bottom of the heat insulation box 4 is exposed.

[0043] After the second insulation cover 10 is opened, the heat-conducting copper plate 6 can fully contact the hot air entering through the vent 3, and at the same time efficiently absorb the residual heat generated by the operation of the equipment inside the box 1. The heat-conducting copper plate 6 quickly conducts the absorbed heat to the phase change material filled inside the insulation box 4. After being heated, the phase change material changes from solid to liquid, and stores heat stably through the phase change process. During this process, the C-shaped first insulation cover 8, which is installed on the outside of the box 1 near the heat dissipation copper plate 7, can cover the other sides of the heat dissipation copper plate 7 except for the side that is in contact with the inner wall of the box 1, to prevent the heat absorbed during the day from being lost to the air inside the box or the outside of the box 1 through the heat dissipation copper plate 7, and ensure that the heat is concentrated and stored in the phase change material, thereby improving the heat absorption and storage efficiency during the day and laying the foundation for heat release at night.

[0044] As night falls, the outside temperature drops sharply in areas with large day-night temperature differences, and the temperature inside the box also decreases accordingly. After sensing the low temperature, the heat-conducting copper column 16 transfers the cold energy to the thermally expanding and contracting liquid in the liquid storage tube 15. The liquid shrinks in volume when it encounters cold, and the elastic restoring force of the return spring 21 pushes the first piston block 17 to return to its original position along the axial direction of the liquid storage tube 15. This causes the contact rod 19 and the limiting rack 20 to move in opposite directions synchronously, which in turn causes the limiting gear 14 and the rotating shaft 11 to rotate in opposite directions. This causes the second heat insulation cover 10 to rotate around the rotating shaft 11 towards the bottom of the heat insulation box 4 until it is completely covered by the heat-conducting copper plate 6. At this time, the sealing ring 13 fixed on the edge of the heat insulation box 4 near the second heat insulation cover 10 can make the second heat insulation cover 10 fit tightly with the bottom of the heat insulation box 4, completely blocking the heat inside the heat insulation box 4 from being lost to the outside cold air through the heat-conducting copper plate 6, thus achieving heat preservation at night.

[0045] Meanwhile, as the temperature decreases at night, the phase change material inside the insulation box 4 changes from liquid to solid and releases the heat stored during the day. The heat is efficiently conducted through the vertically fixed heat dissipation copper fins 7 at equal intervals inside the top of the insulation box 4. Because one side of the heat dissipation copper fins 7 is tightly attached to the inner wall of the box 1, and the first insulation cover 8 restricts the heat from spreading in other directions, the heat is forced to be directionally transferred to the inner wall of the box 1, so that the temperature of the inner wall of the box 1 is always maintained above the air dew point, effectively preventing condensation from forming on the inner wall of the box 1 and on the internal secondary components and cable joints, avoiding the hidden dangers of decreased insulation performance and component corrosion. The whole process does not require electric drive. The automatic opening and closing of the second insulation cover 10 is achieved through the linkage of thermal expansion and contraction of the liquid and mechanical structure. Combined with the heat storage and release of the phase change material and the directional heat conduction of the first insulation cover 8, a complete day and night heat circulation system is formed, which specifically solves the condensation problem of ring network boxes in areas with large day and night temperature differences, and significantly improves the reliability of equipment operation and environmental adaptability.

[0046] Example 2: Please refer to Figure 10 - Figure 13 This embodiment further illustrates Example 1, wherein an injection repair component is provided on the outside of the liquid storage tank 5.

[0047] The fluid injection repair assembly includes a fixing frame 22 and a piston cylinder 23. The fixing frame 22 is fixedly installed on the outside of the mounting partition 9, and the piston cylinder 23 is fixedly installed inside the fixing frame 22. A second piston block 32 is slidably and sealed inside the piston cylinder 23, and a connecting rod 25 is vertically fixed at the top center of the second piston block 32.

[0048] A connecting bracket 24 is fixedly installed at the top of the connecting rod 25. One end of the connecting bracket 24 is fixedly installed on the outside of one side of the abutting rod 19. An inlet pipe 26 and an outlet pipe 28 are fixedly installed through the bottom of the piston cylinder 23. A first check valve 27 is fixedly connected inside the inlet pipe 26 near the piston cylinder 23. A second check valve 29 is fixedly connected inside the outlet pipe 28 near the piston cylinder 23.

[0049] One end of the inlet pipe 26 is fixedly installed inside the bottom of the liquid storage tank 5. An adder pipe 33 is fixedly installed through one side of the top of the liquid storage tank 5. A sealing cap 34 is threaded onto the top of the adder pipe 33. One end of the drain pipe 28 is fixedly installed inside the top of the insulation box 4. An S-shaped pipe 30 is fixedly connected to the end of the drain pipe 28 inside the top of the insulation box 4. Several nozzles 31 facing the phase change material are fixed at equal intervals on the bottom wall of the S-shaped pipe 30.

[0050] In this embodiment, the automatic repair of the phase change material inside the insulation box 4 is achieved through the pure mechanical linkage between the liquid injection repair component and the drive cover component. Its working principle revolves around the logic of drawing out the repair liquid when the second insulation cover 10 is open during the day and dripping the repair liquid when the second insulation cover 10 is closed at night. The specific process is as follows:

[0051] During the day, as the outside temperature rises, the liquid in the reservoir tube 15 of the drive cover assembly expands due to heat, pushing the first piston block 17 and the contact rod 19 to move synchronously (this process is consistent with Embodiment 1, ultimately causing the second heat insulation cover 10 to open). Since one end of the connecting frame 24 of the injection repair assembly is fixed to the outside of the contact rod 19, the movement of the contact rod 19 will drive the connecting frame 24 to move synchronously, thereby pulling the connecting rod 25 fixed to the connecting frame 24, causing the connecting rod 25 to drive the second piston block 32, which is slidably and sealed inside the piston cylinder 23, to slide upward along the axial direction of the piston cylinder 23. At this time, a negative pressure is formed in the space below the second piston block 32 inside the piston cylinder 23. The repair liquid, such as hydrophobic silicone oil, stored in the reservoir 5 is drawn into the piston cylinder 23 through the first one-way valve 27 and the inlet pipe 26, completing the suction and storage of the repair liquid. The entire suction process requires no additional power and is achieved entirely by the mechanical movement of the drive cover assembly. The fixed bracket 22 provides stable support for the piston cylinder 23, ensuring that the second piston block 32 slides without deviation and guaranteeing suction efficiency. At the same time, the addition pipe 33 at the top of the reservoir 5 cooperates with the sealing cap 34 to conveniently replenish the repair liquid when it is insufficient. The sealing cap 34 can prevent the liquid from getting damp or contaminated, ensuring the stability of the repair liquid performance.

[0052] As night falls and the outside temperature drops, the liquid in the drive cover assembly, which expands and contracts with temperature changes, contracts. The return spring 21 pushes the first piston block 17 and the contact rod 19 to reset in the opposite direction (this process is consistent with Embodiment 1, ultimately closing the second insulation cover 10). The reset of the contact rod 19 causes the connecting frame 24 and the connecting rod 25 to move in opposite directions synchronously, pushing the second piston block 32 to slide downward along the piston cylinder 23 axially, squeezing the repair liquid stored in the piston cylinder 23. At this time, the liquid pressure increases, and the repair liquid is delivered through the drain pipe 28 and the second one-way valve 29 to the S-shaped pipe 30 inside the top of the insulation box 4. The curved structure of the S-shaped pipe 30 allows the liquid to be evenly distributed, and then through several nozzles 31 fixed at equal intervals on its bottom pipe wall, the repair liquid is evenly dripped into the phase change material inside the insulation box 4.

[0053] The dripped repair liquid can precisely fill the microscopic cracks caused by long-term day-night phase change cycles in the phase change material, restore the internal heat conduction pathways of the phase change material, and avoid uneven heat storage and heat release discontinuity caused by cracks. At the same time, the hydrophobicity of the liquid can form a protective film on the surface of the phase change material, blocking the intrusion of trace moisture and further delaying the aging of the material. This repair process is synchronized with the nighttime heat release process in Example 1. The repaired phase change material can more efficiently transfer heat to the inner wall of the box 1 through the heat dissipation copper plate 7, which works synergistically with the heat preservation effect after the second insulation cover 10 is closed. This ensures that the anti-condensation effect is not interrupted and extends the service life of the phase change material. The entire liquid injection repair process is purely mechanically driven and requires no power support.

[0054] Meanwhile, from a structural installation perspective, the first one-way valve 27 is fixed and open at the end of the inlet pipe 26 near the piston cylinder 23, allowing liquid to flow only from the storage tank 5 towards the piston cylinder 23; the second one-way valve 29 is fixed and open at the end of the outlet pipe 28 near the piston cylinder 23, allowing liquid to flow only from the piston cylinder 23 towards the insulation box 4. This strictly restricts the one-way flow of liquid, ensuring that the repair liquid only enters and does not exit during the suction stage and only exits and does not enter during the discharge stage, avoiding repair failure or liquid contamination caused by backflow, ensuring that the repair liquid accurately acts on the phase change material, and significantly improving the long-term operational reliability of the equipment in areas with large day-night temperature differences.
