Description

Technical Field

[0001] This application relates to the technical field of ring main units, and in particular to a ring main unit that integrates primary and secondary maintenance for convenient upkeep. Background Technology

[0002] A ring main unit is a compact switchgear used in medium-voltage power distribution systems. It connects cables in different directions and is responsible for distributing power to various user areas.

[0003] In related technologies, a ring main unit includes a box body, a mounting plate installed inside the box body, and electrical components installed inside the box body. The box body includes a top plate, side plates, and a bottom plate. The side plates have inlet and outlet holes for wires to be introduced and led out, and several heat dissipation holes for heat dissipation.

[0004] However, during the use of the aforementioned ring main unit, the electrical components inside the unit generate a large amount of heat, resulting in a temperature difference between the inside and outside of the unit. This causes condensation to easily form on the inner wall of the unit, which is especially noticeable in cold weather. This leads to high humidity inside the unit, moisture-induced short circuits in the electrical components, seriously affecting the normal use of the ring main unit and the safe operation of the power system. Furthermore, subsequent maintenance requires disconnecting the switches on the electrical components one by one to cut off the power, resulting in low maintenance efficiency. Therefore, improvements are needed. Summary of the Invention

[0005] To improve the maintenance efficiency of ring main units, this application provides a convenient maintenance method for ring main units that integrates primary and secondary maintenance.

[0006] The technical solution for a convenient maintenance ring main unit integrating primary and secondary circuits provided in this application is as follows:

[0007] A convenient maintenance ring main unit with integrated primary and secondary circuits includes a housing and several electrical components disposed within the housing. The housing includes a top plate, side plates, and a bottom plate. Several heat dissipation holes are provided on the side plates for heat dissipation. Each electrical component is equipped with a switch, and the switch has a connecting groove. A magnetic block is provided on the groove wall. A drive rod is also connected to the switch, and the drive rod has several trigger rods. An adsorption block with the opposite magnetic properties to the magnetic block is provided at the end of the trigger rod away from the drive rod, and the adsorption block extends into the connecting groove.

[0008] By adopting the above technical solution, when the electrical components inside the enclosure become damp and short-circuit, simply rotating the drive rod in the direction of opening will disconnect the switching blades on all electrical components, eliminating the need for personnel to disconnect the switching blades on each component individually. This saves time, improves the maintenance efficiency of the ring main unit, and the trigger rod increases the torque when rotating the switching blades, thereby reducing the force required for opening and closing, making it more effortless. During normal operation, the drive rod can also be directly removed from the switching blades, allowing the suction block to disengage from the connecting slot, enabling individual operation of the switching blades on a single electrical component. The operation is simple.

[0009] Optionally, it also includes a dehumidification mechanism disposed on the inner wall of the side panel. The dehumidification mechanism includes a sliding plate slidably disposed on the inner wall of the side panel and a driving assembly for driving the sliding plate to slide. The sliding plate is tightly fitted to the side panel, and a drain hole for water to flow out of the box is opened on the side of the side panel near the bottom plate.

[0010] By adopting the above technical solution, when condensation forms on the inner wall of the enclosure, the drive assembly will drive the sliding plate to slide tightly against the inner wall of the side plate, causing the condensation on the inner wall of the side plate to be scraped off onto the bottom plate. The condensation then flows out of the enclosure through the drain holes, thus reducing the possibility of condensation buildup leading to increased humidity inside the enclosure and preventing electrical components from short-circuiting due to moisture. This helps ensure the normal operation of the ring main unit. The dehumidification action does not affect the normal ventilation function of the heat dissipation holes, balancing heat dissipation and moisture prevention requirements.

[0011] Optionally, the drive assembly includes a rotating rod rotatably mounted on the inner wall of the side plate, a brake mounted on the rotating rod, and a connecting rod rotatably mounted on the rotating rod. One end of the connecting rod is rotatably connected to the sliding plate, and the other end is rotatably connected to the rotating rod. The rotating rod and the connecting rod are located on the side of the sliding plate away from the bottom plate, and the brake can drive the rotating rod to rotate.

[0012] By employing the above technical solution, when dehumidification of the inner wall of the cabinet is required, the braking component drives the rotating rod to rotate, thereby causing the connecting rod to rotate relative to the rotating rod and simultaneously rotate relative to the sliding plate. This increases or decreases the angle between the rotating rod and the connecting rod, and simultaneously causes the rotating rod and the connecting rod to extend or retract between the rotating rod's axis and the sliding plate. Through the lever principle, the small-amplitude rotation of the rotating rod is converted into a large-amplitude sliding of the connecting rod, causing the sliding plate to slide towards or away from the bottom plate, thus scraping the condensate on the inner wall of the side plate onto the bottom plate. Furthermore, the rotating rod and the connecting rod are located above the sliding plate on the side plate, and will not interfere with the layout of the electrical components inside the cabinet.

[0013] Optionally, the sliding plate includes a sliding part and moisture-absorbing cotton disposed on both sides of the sliding part. The moisture-absorbing cotton is disposed on both sides of the sliding part near and away from the side plate, and the connecting rod is rotatably connected to the sliding part.

[0014] By adopting the above technical solution, when the sliding plate slides on the inner wall of the side plate, if the sliding plate fails to completely scrape the condensate on the side plate onto the bottom plate, the moisture-absorbing cotton near the side plate can absorb the remaining condensate, completely cleaning the condensate from the side plate. This further reduces the possibility of condensate remaining inside the cabinet, thereby reducing the possibility of humid air corroding electrical components. In addition, the moisture-absorbing cotton away from the side plate can absorb moisture from the air inside the cabinet, further reducing the humidity inside the cabinet.

[0015] Optionally, the braking component includes a hydrophilic plate rotatably mounted on a rotating rod, an elastic element mounted on a sliding plate, and a magnetic block mounted on the side of the sliding plate away from the connecting rod. The sliding part is provided with a magnetic strip with magnetic properties opposite to those of the magnetic block. The magnetic block is provided with a squeezing plate on the side near the sliding plate. The distance between the squeezing plate and the side plate is less than the total thickness of the sliding part and the absorbent cotton. The elastic element has a tendency to drive the sliding plate to slide away from the bottom plate.

[0016] By adopting the above technical solution, when condensation forms on the inner wall of the cabinet, the hydrophilic plate absorbs a large amount of condensation, increasing its overall weight. This causes the hydrophilic plate to slide towards the bottom plate under gravity, pushing the connecting rod towards the bottom plate. Simultaneously, the absorbent cotton also absorbs some condensation, increasing its weight and automatically driving the sliding plate towards the bottom plate. At this point, the magnetic strip and magnetic block on the sliding plate get closer, increasing the magnetic force of the magnetic block on the magnetic strip, thus adsorbing the sliding plate to the side panel near the bottom plate. Simultaneously, the condensation on the inner wall of the side panel is absorbed into the absorbent cotton. When the sliding plate slides to the squeezing plate, the squeezing plate compresses the absorbent cotton, causing the condensation to drain and fall onto the bottom plate, then drain out of the cabinet through the drain hole. The increased weight of the hydrophilic plate upon contact with moisture drives the rotating rod, achieving automatic dehumidification when humidity is high, eliminating the need for a separate drive source to drive the rotating rod, thus simplifying the drive assembly structure. The magnetic blocks and strips hold the sliding plate in place, ensuring the squeegee action is complete. After the absorbent cotton absorbs the condensate, the water is expelled by the squeezing plate, reducing its weight and allowing the sliding plate to slide away from the base plate under the action of the elastic element. The sliding plate then returns to its original position, ready for the next condensation to form for dehumidification.

[0017] Optionally, a sliding groove is provided on the side plate, and the hydrophilic plate is slidably disposed in the sliding groove. The contact surface between the groove wall and the hydrophilic plate is smooth, and an absorbent cloth is provided on the groove wall near the bottom plate.

[0018] By adopting the above technical solution, when the weight of the hydrophilic plate absorbed condensed water increases, the hydrophilic plate will slide in the sliding groove. The groove wall can limit the sliding trajectory of the hydrophilic plate, ensuring that it slides only in the vertical direction. This reduces the risk of mechanical jamming caused by the hydrophilic plate's skewness, thus stabilizing the pushing effect of the hydrophilic plate on the connecting rod and rotating rod. Furthermore, the smooth, almost frictionless contact surface between the hydrophilic plate and the sliding groove improves the sensitivity and timeliness of the hydrophilic plate's humidity sensing. When the hydrophilic plate slides to abut against the groove wall near the bottom plate, it will contact the absorbent cloth, absorbing the condensed water on the hydrophilic plate onto the absorbent cloth. This reduces the weight of the hydrophilic plate, facilitating the elastic element to reset the sliding plate.

[0019] Optionally, the elastic element includes a return spring disposed on the side of the sliding plate away from the base plate, a mounting block is provided on the inner wall of the side plate, a guide post is provided on the mounting block, the return spring is sleeved on the guide post, and a mounting hole for the guide post to pass through is provided on the sliding plate.

[0020] By adopting the above technical solution, when the sliding plate slides towards or away from the base plate, the connecting spring will extend or retract. The guide post can limit the extension and retraction direction of the connecting spring, making the extension and retraction path of the connecting spring vertical. This makes the connecting spring less prone to tilting, thereby ensuring the resetting effect of the connecting spring on the sliding plate. At the same time, it is not easy to damage the connecting spring, thus extending its service life.

[0021] Optionally, the connecting rod includes a fixed section and a telescopic section. The fixed section has a movable groove for accommodating the telescopic section. The telescopic section is slidably disposed in the movable groove. A connecting spring is provided between the telescopic section and the groove wall of the movable groove. The fixed section is rotatably connected to a rotating rod, and the sliding plate is rotatably disposed on the telescopic section.

[0022] By adopting the above technical solution, when the sliding plate slides towards the side closer to the bottom plate, the telescopic section slides towards the bottom plate in the movable groove, increasing the overall length of the connecting rod. At this time, the connecting spring is stretched, allowing the sliding plate to cover a longer area of ​​the side plate, thus improving its dehumidification effect. Conversely, when the sliding plate slides away from the bottom plate, the stretched connecting spring contracts, assisting the telescopic section in retracting and facilitating the sliding plate's return to its original position. Furthermore, the overall length of the connecting rod shortens compared to a fixed length, allowing the sliding plate to move upwards to a position closer to the top plate. This allows the sliding plate to cover a larger area of ​​the side plate during its next slide, further enhancing its dehumidification effect.

[0023] Optionally, a guide groove is provided on the side of the base plate near the side plate, the bottom wall of the guide groove is inclined, and the drain hole is opened on the side plate and near the lowest point of the bottom wall of the guide groove.

[0024] By adopting the above technical solution, after the condensate on the side panel is scraped onto the bottom plate, the condensate preferentially enters the drainage channel. Then, the inclined bottom wall of the drainage channel collects the condensate to the lowest point, and then the condensate flows out of the cabinet through the drain hole, reducing the possibility of water accumulation. The drain hole is located at the lowest point of the bottom wall of the drainage channel, utilizing the gravity of the condensate for natural drainage, which improves drainage efficiency and reduces the possibility of condensate remaining on the bottom plate, thus helping to reduce the humidity inside the cabinet.

[0025] In summary, this application includes at least one of the following beneficial technical effects:

[0026] 1. By setting drive rods and trigger rods on the opening and closing switches of electrical components, the opening and closing switches of multiple electrical components can be connected together, enabling the simultaneous opening and closing of the opening and closing switches of multiple electrical components at one time, thus improving the efficiency of fault repair.

[0027] 2. The sliding plate moves the moisture-absorbing cotton to scrape the water on the inner wall of the side panel onto the bottom plate and drain it through the drain hole. This reduces the amount of condensation that remains in the box, which helps to ensure the normal operation of electrical components.

[0028] 3. When condensation forms inside the chamber, the hydrophilic plate and absorbent cotton will automatically absorb the condensation and increase their own weight, thereby automatically pushing the connecting rod and sliding plate towards the bottom plate to start dehumidification. When the absorbent cotton slides into place, the water in the absorbent cotton will be squeezed out by the squeezing plate, thereby reducing the weight of the absorbent cotton and making it easier to reset under the action of the elastic element for the next dehumidification operation.

[0037] The following is in conjunction with the appendix Figure 1-6 This application will be described in further detail.

[0038] This application discloses a ring network box that integrates primary and secondary maintenance.

[0039] Reference Figure 1 and Figure 2 A convenient maintenance ring main unit with integrated primary and secondary circuits includes a housing 1 and several electrical components 2, wherein the electrical components 2 are located inside the housing 1 and are equipped with switch blades 21. The housing 1 includes a top plate 11, a side plate 12 and a bottom plate 13. The side plate 12 is provided with several heat dissipation holes 121 for heat dissipation and drainage holes 122 for water supply to flow out of the housing 1.

[0040] Reference Figure 2 and Figure 3 The switch 21 has a connecting groove 211, and a magnetic block 212 is provided on the groove wall. The switch 21 is also connected to a drive rod 213, and a number of trigger rods 214 are fixed on the drive rod 213. Each trigger rod 214 corresponds to a switch 21. The end of the trigger rod 214 away from the drive rod 213 is provided with an adsorption block 215 with the opposite magnetic properties to the magnetic block 212. The adsorption block 215 extends into the connecting groove 211, so that the switch 21 can be connected together by the magnetic attraction between the adsorption block 215 and the magnetic block 212, which facilitates the disassembly and connection of the switch 21 and the trigger rod 214.

[0041] Reference Figure 4 Each of the bottom plates 13 and the side plates 12 is provided with a guide groove 131. The bottom wall of the guide groove 131 is inclined. The drain hole 122 is opened at the lowest point of the bottom wall of the side plate 12 near the guide groove 131 so that condensed water can flow out from the drain hole 122.

[0042] Reference Figure 4 Each side panel 12 has a dehumidification mechanism 3 on its inner wall. The dehumidification mechanism 3 includes a sliding plate 31 slidably mounted on the inner wall of the side panel 12 and a driving assembly 4 for driving the sliding plate 31 to slide. The sliding plate 31 includes a sliding part 311 and absorbent cotton 312 disposed on both sides of the sliding part 311. The absorbent cotton 312 is disposed on both sides of the sliding part 311, near and away from the side panel 12, with the absorbent cotton 312 near the side panel 12 in close contact with it. The absorbent cotton 312 can be made of highly absorbent sponge material, which has strong water absorption and can quickly absorb condensation. Alternatively, cotton fiber material with good moisture absorption properties can be used. The sliding part 311 and the absorbent cotton 312 can be connected by adhesive, a simple and secure connection method. Alternatively, a snap-fit ​​connection can be used for easy replacement of the absorbent cotton 312.

[0043] Reference Figure 4 and Figure 5 The drive assembly 4 includes a rotating rod 41 rotatably mounted on the inner wall of the side plate 12, a brake element 42 mounted on the rotating rod 41, and a connecting rod 43 rotatably mounted on the rotating rod 41. The rotating rod 41 is rotatably mounted on the inner wall of the side plate 12 via bearings, which reduces friction during rotation and makes rotation smoother. The brake element 42 includes a hydrophilic plate 421 rotatably mounted on the rotating rod 41, an elastic element 422 mounted on the sliding plate 31, and a magnetic block 423 mounted on the side plate 12. The hydrophilic plate 421 can be made of a hydrophilic plastic material, such as polyvinyl alcohol, which can quickly absorb moisture. Alternatively, a metal plate coated with a hydrophilic coating can be used.

[0044] Reference Figure 5 and Figure 6The connecting rod 43 includes a fixed section 431 and a telescopic section 432. The fixed section 431 has a movable groove 433 for accommodating the telescopic section 432. The telescopic section 432 is slidably disposed in the movable groove 433. A connecting spring 434 is provided between the telescopic section 432 and the groove wall of the movable groove 433. The telescopic section 432 is rotatably connected to the sliding plate 31. The fixed section 431 is rotatably connected to the rotating rod 41. The rotating rod 41 and the connecting rod 43 are both disposed on the side of the sliding plate 31 away from the bottom plate 13.

[0045] Reference Figure 5 The magnetic block 423 is located on the side of the sliding plate 31 away from the connecting rod 43. The sliding part 311 is provided with a magnetic strip 313 with the opposite magnetic properties to the magnetic block 423. The side of the magnetic block 423 near the sliding plate 31 is provided with a squeezing plate 424 on the side plate 12. The distance between the squeezing plate 424 and the side plate 12 is less than the total thickness of the sliding part 311 and the moisture-absorbing cotton 312, so that when the magnetic block 423 and the magnetic strip 313 are attracted, the squeezing plate 424 can squeeze the moisture-absorbing cotton 312 to deform it, thereby expelling moisture.

[0046] Reference Figure 4 and Figure 5 The inner wall of the side plate 12 is provided with a mounting block 425, and a guide post 426 is fixed on the mounting block 425. The sliding plate 31 is provided with a mounting hole 314, and the guide post 426 passes through the mounting hole 314. The elastic element 422 includes a return spring 427 provided on the side of the sliding plate 31 away from the bottom plate 13. The return spring 427 is sleeved on the guide post 426, and the return spring 427 has a tendency to drive the sliding plate 31 to slide away from the bottom plate 13.

[0047] Reference Figure 5 A sliding groove 123 is provided on the side plate 12. The sliding groove 123 is arc-shaped. The hydrophilic plate 421 is slidably disposed in the sliding groove 123. The contact surface between the groove wall of the sliding groove 123 and the hydrophilic plate 421 is smooth to reduce the resistance when the hydrophilic plate 421 slides in the sliding groove 123 and increase the sensitivity of the hydrophilic plate 421 to humidity. The arc shape of the sliding groove 123 matches the circumferential arc shape of the rotating rod 41. An absorbent cloth 124 is provided on the groove wall of the sliding groove 123 near the bottom plate 13.

[0048] Reference Figure 5 With the above settings, when condensation is adsorbed on the hydrophilic plate 421, the hydrophilic plate 421 will automatically slide towards the bottom plate 13 under the action of gravity, thereby causing the rotating rod 41 to rotate towards the bottom plate 13, and at the same time causing the connecting rod 43 to push the sliding plate 31 towards the bottom plate 13, so that the moisture-absorbing cotton 312 absorbs the condensation on the side plate 12 and then discharges it from the box 1.

[0049] The implementation principle of the primary and secondary integrated convenient maintenance ring main unit in this application embodiment is as follows: When the electrical component 2 is damp and short-circuited, the drive rod 213 can be directly rotated to simultaneously disconnect the opening and closing switches 21 of multiple electrical components 2, thereby improving the fault repair efficiency of the ring main unit. When condensation forms on the inner wall of the side plate 12, the weight of the hydrophilic plate 421 and the sliding plate 31 will increase, causing the sliding plate 31 to slide closer to the bottom plate 13. During the sliding process, the magnetic block 423 will simultaneously generate an adsorption force on the magnetic strip 313 on the sliding plate 31, causing the sliding plate 31 to slide to the squeezing plate 424. Then, the squeezing plate 424 will squeeze the condensation in the moisture-absorbing cotton 312 into the guide groove 131, and then the condensation will be discharged from the box 1 through the drain hole 122. After the squeezing plate 424 squeezes out the condensed water from the absorbent cotton 312, the weight of the sliding plate 31 is reduced. Simultaneously, the hydrophilic plate 421 has also come into contact with the absorbent cloth 124, thus reducing its weight as well. At this point, the sliding plate 31 and the hydrophilic plate 421 will reset under the action of the return spring 427, so that when condensation occurs on the inner wall of the side plate 12 next time, the condensation on the side plate 12 can be scraped off. Through the above configuration, when condensation occurs inside the housing 1, the dehumidification mechanism 3 can automatically drain the water, which helps maintain a dry internal environment, reduces the probability of failure of electrical components 2, and improves the reliability and safety of the ring main unit.

[0050] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
