Description

Technical Field

[0001] This invention relates to the field of power distribution equipment technology, and in particular to a highly integrated primary and secondary fusion ring network box. Background Technology

[0002] A ring main unit is an electrical device that houses a group of power transmission and distribution equipment (high-voltage switchgear) within a metal or non-metal insulated cabinet or is configured as a modular ring network power supply unit. Its core components utilize load switches and fuses. It offers advantages such as simple structure, small size, low cost, improved power supply parameters and performance, and enhanced power supply safety. It is widely used in substations and prefabricated substations in load centers such as urban residential areas, high-rise buildings, large public buildings, and factories.

[0003] As a core device in power distribution networks, ring main units (RMS) undertake critical functions such as power distribution, line protection, and fault isolation. Existing RMS units suffer from the following technical deficiencies in practical applications: their rainproof structure design is unreasonable, often using integrated bolt-fixed rainproof baffles, requiring complete disassembly and replacement when partially damaged; and the lack of dedicated insulation between the rainproof structure and the enclosure makes the weak current circuits of the secondary monitoring and control unit susceptible to interference from the primary high-voltage circuit. Therefore, this paper proposes to develop a highly integrated primary and secondary fusion RMS. Summary of the Invention

[0004] In view of the above-mentioned problems existing in the prior art, the purpose of the present invention is to provide a highly integrated primary and secondary fusion ring main unit that integrates rainproof, insulation and lightning protection functions, improves outdoor safety and operation and maintenance convenience, and adapts to the power distribution needs of primary and secondary fusion.

[0005] This invention is achieved using the following technical solution: a highly integrated primary and secondary fusion ring network box, comprising a ring network box body, multiple sets of rainproof plate assemblies, insulators, support bases, connecting slides, fixing bolts, lightning conductor assemblies, and support assemblies; Multiple sets of the aforementioned rainproof plate components are installed on top of the ring network box in a splicing manner to achieve rain protection for the ring network box; The insulator is installed between the ring network box and the rainproof plate assembly via a support base and a connecting slide. The support base and the ring network box are fixedly connected by fixing bolts, and the connecting slide and the rainproof plate assembly are fixedly connected by bolts. By utilizing the insulation characteristics of the insulator, an insulating isolation state is formed between the rainproof plate assembly and the ring network box. The lightning-attracting component is installed on one side of the connecting slide, and a grounding wire is fixedly connected to the connecting slide. When lightning strikes, the lightning-attracting component can conduct the lightning to the connecting slide and then conduct the lightning to the underground grounding terminal through the grounding wire to complete the lightning protection grounding. The support assembly is installed laterally between two insulators. The support assembly can lock and fix the relative positions of the two insulators to ensure that the insulators maintain a preset distance after installation.

[0006] As a further improvement to the above solution, the rainproof panel assembly has a recessed V-shaped groove in the middle, and the inner cavity of the V-shaped groove is symmetrically provided with baffle plates. The two together form a rain collection groove, which can collect rainwater on rainy days and achieve natural cooling of the rainproof panel assembly. The rainproof panel assembly has a combination plate one and a combination plate two on both sides, and the combination plate one and the combination plate two are adapted to be spliced ​​together. The top of the combination plate one is provided with a limiting protrusion, and the bottom of the combination plate two is provided with a limiting groove that matches the limiting protrusion. Adjacent rainproof panel assemblies are spliced ​​together by the combination plate one, the combination plate two, the limiting protrusion, and the limiting groove.

[0007] As a further improvement to the above solution, the connecting slide includes a U-shaped connecting plate and a U-shaped support plate; the top of the U-shaped connecting plate is provided with a connecting ear plate, and the bottom is provided with two guide grooves; a guide bolt passes through the inner cavity of the guide groove, and the U-shaped support plate is installed at the bottom of the U-shaped connecting plate by the guide bolt, and a guide nut is screwed on the bottom end of the guide bolt; the guide bolt can slide along the inner cavity of the guide groove, and when disassembling the rainproof plate assembly, it pushes the insulator so that its bottom end is detached from the top of the support base.

[0008] As a further improvement to the above solution, a limiting baffle is provided on one side of the U-shaped connecting plate, and a long bolt is provided through the side wall of the U-shaped support plate. The threaded end of the long bolt passes through the limiting baffle and is screwed with a limiting nut. A compression spring is provided between the limiting nut and the limiting baffle. When the bottom end of the insulator is inserted into the top of the support base, the compression spring is in an elastic compression state to ensure the installation stability of the insulator.

[0009] As a further improvement to the above solution, the lightning attracting assembly includes a lightning attracting base, a lightning attracting support rod, and a lightning attracting rod; the lightning attracting base is sleeved on the bottom of the U-shaped connecting plate, and the lightning attracting base is snapped and fixed to the bottom of the limiting baffle; the lightning attracting support rod is fixed to one side of the lightning attracting base; the lightning attracting rod is fixed to the free end of the lightning attracting support rod away from the lightning attracting base, and the lightning attracting rod is suspended above the rainproof plate assembly; the effective attraction of lightning is achieved by utilizing the tip discharge characteristics of the lightning attracting rod.

[0010] As a further improvement to the above solution, the support assembly includes an adjusting plate and two sliding plates, the two sliding plates being slidably mounted at both ends of the adjusting plate; the ends of the sliding plates are provided with rotatable snap-fit ​​plates for snap-fitting and fixing insulators.

[0011] As a further improvement to the above solution, a U-shaped limiting frame is provided at the bottom of both ends of the adjusting plate, and the sliding plate can slide linearly within the U-shaped limiting frame; an adjusting slot is provided at the top of the adjusting plate, and an adjusting bolt connected to the sliding plate is provided in the inner cavity of the adjusting slot, and the position of the sliding plate is locked by the adjusting bolt and the locking nut.

[0012] As a further improvement to the above solution, the sliding plate has an arc-shaped groove at its end, and the locking plate can be rotatably installed on the end of the sliding plate by rotating bolts with a rotation angle of 0-90°. One end of the locking plate is provided with a locking bolt, which is locked by engaging with the arc-shaped groove.

[0013] Compared with the prior art, the beneficial effects of the present invention are as follows: This invention adopts a combined structure of "interlocking rainproof panel + flexible connecting slide + adjustable support component" to optimize the entire process of maintenance, disassembly, and adaptation; the interlocking rainproof panel component is designed to achieve precise splicing through "convex strip-groove" cooperation; at the same time, it integrates a V-shaped rain collection groove structure to use natural rainwater to cool the component, slow down outdoor sun exposure aging, and take into account both maintenance convenience and durability; This invention uses an insulator structure to construct an insulating barrier between the rainproof plate and the enclosure, avoiding high-voltage interference with the secondary unit; it constructs a three-in-one protection system of "insulation isolation + lightning protection grounding + sealing and rainproof", which is suitable for the complex operating environment of primary and secondary integration; This invention adopts a "standardized component + adjustable structure" design. The design includes a connecting slide with a guide groove and a compression spring to achieve an elastic connection between the insulator and the rainproof plate. During disassembly and assembly, the insulator can be detached from its positioning by sliding, without the need for complete disassembly. The matching adjustable support component, through the cooperation of the sliding plate and the rotating snap-fit ​​plate, enables flexible adjustment and quick locking of the insulator spacing, taking into account both installation stability and ease of disassembly and assembly.

[0019] To keep the following description of the embodiments of this disclosure clear and concise, detailed descriptions of known functions and known components are omitted.

[0020] Please combine Figure 1-11 As shown, this embodiment of the invention provides a highly integrated primary and secondary fusion ring main unit, the main structure of which includes a ring main unit 1, multiple sets of rainproof plate assemblies 2, insulators 3, support bases 4, connecting slides 5, fixing bolts 6, lightning conductor assemblies 7, and support assemblies 8; the ring main unit 1 is a cuboid structure, with a reserved area for rainproof plate installation on the top of the unit, and L-shaped clamping plates 11 are symmetrically fixed on the front and rear sides. The L-shaped clamping plates 11 are integrally bent at the top of the unit, and their material is galvanized steel plate, which has sufficient support strength; the top of the L-shaped clamping plate 11... Multiple positioning screw holes 12 are evenly provided along the length direction. The diameter of the positioning screw holes 12 is M10 (the spacing between adjacent screw holes is 100mm), which are used to support the positioning and installation of the base 4. The top of the box is also provided with a grounding terminal for connecting the grounding device to achieve overall grounding protection. In the prior art, the rainproof baffle of the ring network box 1 is mostly fixed with bolts. This structure requires the entire baffle to be replaced when the rainproof baffle is partially damaged, which is inconvenient. Moreover, there is no insulation and lightning protection structure between the rainproof baffle and the ring network box 1, which poses a safety hazard. Figures 1 to 5 As shown, the rainproof plate assembly 2 adopts a splicing structure design and is made of insulating flame-retardant fiberglass, which has good rainproof, insulation and anti-aging properties. Multiple rainproof plate assemblies 2 are spliced ​​and installed on the top of the ring network box 1 to achieve rain protection for the ring network box 1. When a single rainproof plate assembly 2 is damaged, it can be disassembled and replaced individually without the need for overall disassembly and assembly. The L-shaped clamping plate 11 is used to clamp and fix the insulator 3, and the top of the L-shaped clamping plate 11 is evenly provided with multiple positioning screw holes 12, which are adapted to the top positioning installation of the rainproof plate assembly 2. Two insulators 3 are vertically positioned between the ring network box 1 and the rainproof plate assembly 2, and the two insulators 3 are symmetrically distributed front and back. Utilizing the insulation characteristics of the insulators 3, an insulating isolation state is formed between the rainproof plate assembly 2 and the ring network box 1. Both the upper and lower ends of the insulators 3 are integrally formed with threaded rods 31, and locking nuts are fitted on the threaded rods 31. The locking nuts facilitate the detachable connection between the insulators 3 and the support base 4 and the connecting slide 5. The support base 4 is installed at the bottom end of the insulators 3, and the support base 4 is snapped into the inner side of the L-shaped clamping plate 11. The support base 4 has a U-shaped structure, and a U-shaped groove 41 is opened in the middle of the top of the support base 4 near the side. The U-shaped groove 41 and the threaded rod 31 at the bottom of the insulator 3 are in clearance fit, and the locking nut on the threaded rod 31 at the bottom of the insulator 3 is not tightened, which makes it easy to snap the bottom end of the insulator 3 into the U-shaped groove 41 of the support base 4. The top of the support base 4 has a mounting hole. The threaded end of the fixing bolt 6 is screwed into the inner cavity of the positioning screw hole 12. The screw end of the fixing bolt 6 passes through the mounting hole on the top of the support base 4 and abuts against the bottom plate of the support base 4. The fixing bolt 6 and the positioning screw hole 12 are connected by threads to fix the position of the support base 4 inside the L-shaped clamping plate 11. A connecting slide 5 is installed between the top of the insulator 3 and the bottom of the rainproof plate assembly 2. A grounding wire is fixedly connected to the connecting slide 5. The lightning conductor 7 is installed on one side of the connecting slide 5, and the free end of the lightning conductor 7 extends above the rainproof plate assembly 2. When lightning strikes, the lightning conductor 7 can conduct the lightning to the connecting slide 5 and introduce the lightning to the ground grounding terminal through the grounding wire to complete the lightning protection grounding. A support assembly 8 is installed horizontally between the two insulators 3. The support assembly 8 can lock and fix the relative position of the two insulators 3 to ensure that the insulators 3 maintain the preset distance after installation and ensure insulation stability. This solution can realize the integrated function of rainproof, insulation and lightning protection, and is suitable for the power distribution needs of primary and secondary integration.

[0021] like Figures 4 to 6As shown, the rainproof panel assembly 2 has a recessed V-shaped groove 21 in the middle (the depth of the V-shaped groove 21 is 20mm and the included angle is 60°). Symmetrical baffle plates 22 are welded to the left and right sides of the inner cavity of the V-shaped groove 21. The two baffle plates 22 and the V-shaped groove 21 together form a rain collection trough. This rain collection trough can collect rainwater on rainy days and use the collected rainwater to naturally cool the rainproof panel assembly 2, reducing the aging rate of the assembly caused by outdoor sun exposure. A combination clamping plate 23 is integrally formed on one side of the rainproof panel assembly 2, and a limiting protrusion 24 is provided on the top of the combination clamping plate 23. The other side of the rainproof panel assembly 2 is integrally formed with the combination... The first card plate 23 is matched with the second card plate 25. The bottom of the second card plate 25 has a limiting groove 26 that matches the limiting protrusion 24. When two adjacent rainproof panel components 2 are spliced, the second card plate 25 is pressed on top of the first card plate 23, and the limiting protrusion 24 is inserted into the inner cavity of the limiting groove 26, which effectively improves the structural stability after splicing and prevents rainwater from leaking from the splicing gap. The bottom of the rainproof panel component 2 is welded with a mounting block 27 with threaded holes. The connecting slide 5 and the mounting block 27 are fixedly connected by bolts to achieve precise positioning and installation of the connecting slide 5 and the rainproof panel component 2. like Figures 7 to 8 As shown, the connecting slide 5 includes a U-shaped connecting plate 51 and a U-shaped support plate 54; connecting ear plates 52 are fixed at both ends of the top of the U-shaped connecting plate 51, and positioning holes that match the threaded holes of the mounting block 27 are opened on the connecting ear plates 52, so as to facilitate the bolts to pass through and realize the positioning and installation of the connecting ear plates 52 and the mounting block 27. Two guide grooves 53 are provided at the bottom of the U-shaped connecting plate 51. Guide bolts 55 are inserted in the guide grooves 53. The bottom end of the guide bolts 55 passes through the top of the U-shaped support plate 54 and is screwed with a guide nut. The guide nut is not tightened, so that the guide bolts 55 can slide along the inner cavity of the guide grooves 53 (sliding stroke is 0-50mm). Then, when disassembling the rainproof plate assembly 2, the insulator 3 is pushed so that its bottom end is disengaged from the inner cavity of the U-shaped slot 41 of the support base 4. The bottom of the U-shaped support plate 54 is provided with a through hole that matches the threaded rod 31 of the insulator 3. The locking nut on the threaded rod 31 at the top of the insulator 3 is tightened and fixed, so that the U-shaped support plate 54 is firmly installed on the top of the insulator 3. A terminal ring 56 is welded on one side of the U-shaped support plate 54. The terminal ring 56 is used to connect and fix the grounding wire to achieve grounding conduction. A limiting baffle 57 is vertically fixed on the side of the U-shaped connecting plate 51 away from the connecting ring 56. A long bolt 58 is installed through the side wall of the U-shaped support plate 54. The threaded end of the long bolt 58 passes through the side wall of the limiting baffle 57 and is screwed with a limiting nut 581. The limiting nut 581 and the threaded end of the long bolt 58 are fixed together by a cylindrical pin to prevent loosening. A compression spring 59 is provided between the limiting nut 581 and the limiting baffle 57. The compression spring 59 is sleeved on the outer wall of the long bolt 58. When the bottom end of the insulator 3 is inserted into the inner cavity of the U-shaped slot 41, the compression spring 59 is in an elastic compression state, which ensures the installation stability of the insulator 3. When the insulator 3 is disassembled, the elastic restoring force of the compression spring 59 can push the U-shaped support plate 54 at the top of the insulator 3, so that the U-shaped support plate 54 slides along the guide groove 53 under the double limiting of the guide bolt 55 and the limiting baffle 57, so as to realize the convenient disassembly of the insulator 3. like Figure 9 As shown, the lightning attracting assembly 7 includes a lightning attracting base 71, a lightning attracting support rod 72, and a lightning rod 73. The lightning attracting base 71 is sleeved on the bottom of the U-shaped connecting plate 51, and the lightning attracting base 71 is snapped and fixed to the bottom of the limiting baffle 57. This snapping structure facilitates the quick assembly and disassembly of the lightning attracting assembly 7 and the U-shaped connecting plate 51. The lightning attracting support rod 72 is welded to one side of the lightning attracting base 71, and the lightning rod 73 is welded to the free end of the lightning attracting support rod 72 away from the lightning attracting base 71. The lightning rod 73 is suspended above the rainproof plate assembly 2, and a preset gap is left between the bottom end of the lightning rod 73 and the top of the rainproof plate assembly 2. The effective attraction of lightning is achieved by utilizing the tip discharge characteristics of the lightning rod 73. like Figures 10 to 11 As shown, the support assembly 8 includes an adjusting plate 81, two sliding plates 82, and two snap-fit ​​plates 83. The snap-fit ​​plate 83 has a Y-shaped structure, with one end being an arc-shaped snap-fit ​​part that can be fitted and snapped onto the outer wall of the insulator 3, and the other end being a straight connecting plate with two assembly holes. U-shaped limiting frames 811 are welded to the bottom of both ends of the adjusting plate 81, and the sliding plate 82 is inserted into the inner cavity of the U-shaped limiting frame 811, so that the sliding plate 82 can slide linearly along the adjusting plate 81 under the limiting action of the U-shaped limiting frame 811. Both ends of the adjusting plate 81 are provided with adjusting slots 812. Adjusting bolts 813 are inserted into the adjusting slots 812. The bottom end of the adjusting bolts 813 passes through the end of the sliding plate 82 and is screwed with a locking nut. Tightening the locking nut can lock the position of the sliding plate 82 on the adjusting plate 81, so that the adjusting plate 81 and the sliding plate 82 are fixedly connected. When the locking nut is loosened, the sliding plate 82 can slide along the adjusting slots 812 to achieve spacing adjustment. An L-shaped support plate 821 is welded to the bottom of the sliding plate 82 away from the adjusting plate 81. The bottom of the L-shaped support plate 821 abuts against the top of the ring network box 1, providing vertical support for the sliding plate 82 and improving the structural stability of the support assembly 8. A snap-fit ​​plate 83 is rotatably mounted on the end of the sliding plate 82 away from the adjusting plate 81 by a rotating bolt 823. A snap-fit ​​bolt 824 passes through the end of the straight connecting plate of the snap-fit ​​plate 83, and an arc-shaped groove 8 matching the snap-fit ​​bolt 824 is opened at the end of the sliding plate 82. 22; Rotate the snap-fit ​​plate 83 around the rotating bolt 823 (rotation angle is 0-90°) so that the snap-fit ​​bolt 824 is snapped into the inner cavity of the arc-shaped snap-fit ​​groove 822. Then tighten the locking nut to fix the position of the sliding plate 82. The outer walls of the two insulators 3 can be snapped together by the arc-shaped snap-fit ​​part of the snap-fit ​​plate 83 to achieve the support and fixation of the distance between the two insulators 3. When disassembling the insulator 3, loosen the locking nut and rotate the snap-fit ​​plate 83 around the rotating bolt 823 to release the snap-fit ​​fixation of the snap-fit ​​plate 83 on the insulator 3 and complete the disassembly of the insulator 3.
