Description

Technical Field

[0001] This application relates to the technical field of substation cable installation, and particularly to a power supply line protection device for a substation. Background Art

[0002] In the power system, the protection of the power supply line in a substation is an important link to ensure the safe and stable transmission of electricity. In order to effectively manage the cables, including dust prevention, moisture protection, and improving the overall aesthetics, a bridge system is widely used for wiring and installation of the power supply lines.

[0003] However, the existing trough bridges usually adopt a single cover design, and the cover is fixed above the bridge through a sliding plug-in method to achieve the enclosed protection of the cables inside the trough. Although this design meets the requirements of dust prevention and moisture protection to a certain extent, its limitations gradually appear when facing bridges with a large span. Specifically, when it is necessary to repair or maintain the cables in the bridge, it is usually necessary to first slide the entire cover off the bridge. Due to limited indoor space, especially in a complex environment such as a substation, the process of disassembling and reinstalling the cover is not only cumbersome but also time-consuming, greatly affecting the work efficiency.

[0004] In addition, the traditional bridge also has deficiencies in cable separation. Since there is no clear separation structure inside the trough, different types or functions of cables are often mixed together, which not only increases the difficulty of maintenance but also reduces the overall aesthetics.

[0005] In view of the above problems, a power supply line protection device for a substation is now designed. Summary of the Utility Model

[0006] The embodiments of this application provide a power supply line protection device for a substation to solve the problem that in the related art, the existing trough bridges usually adopt a single cover design, and in a complex environment such as a substation, the disassembly process of the cover is cumbersome, affecting the work efficiency.

[0007] In a first aspect, a power supply line protection device for a substation is provided, including:

[0008] A bridge, which has a trough inside for accommodating cables;

[0009] A number of cross beams, which are sequentially arranged above the bridge;

[0010] A number of covers, which are arranged between adjacent two cross beams, and the covers are attached to the top of the bridge;

[0011] A number of connecting pieces are provided at the bottom of the cover, and installation grooves adapted to the connecting pieces are opened above the bridge;

[0012] A number of baffles are detachably arranged inside the channel, and the baffles are used to divide the channel to form a plurality of chambers for accommodating cables.

[0013] In some embodiments, the connecting member includes a fixed block and a permanent magnet that are connected to each other. Both the fixed block and the permanent magnet are inserted into the installation groove, and one end of the fixed block is connected to the cover plate.

[0014] In some embodiments, two grips are oppositely arranged above the cover plate.

[0015] In some embodiments, the baffle includes a horizontal plate and a slider that are connected to each other. A number of clamping grooves are formed inside the channel, the slider is inserted into the clamping groove, and the top of the horizontal plate is attached to the cover plate.

[0016] In some embodiments, the baffle includes arc-shaped blocks that are oppositely arranged on both sides of the horizontal plate. The bottom of the arc-shaped block is attached to the bottom of the channel, and obtuse angles are provided at both ends of the bottom of the channel.

[0017] In some embodiments, a cable holder is further included. The bottom of the cable holder is provided with a second slider that is adapted to the clamping groove. The cable holder has a receiving groove for accommodating cables, and both ends of the top of the cable holder are made of elastic material.

[0018] In some embodiments, a number of connection holes are formed at both ends of the cable bridge, and two cable bridges are connected through the connection holes and an external connection piece.

[0019] The embodiment of the present application provides a power supply line protection device for a substation. Through the detachable cover plate design, the inspection and maintenance work of the cables becomes more convenient and efficient. There is no need to disassemble the cover plate as a whole, and only partial opening is required to complete the inspection task, which greatly saves time and labor costs.

[0020] The partitioning function of the baffle makes the cable layout more orderly and reasonable. Different types or functions of cables are separated in different chambers, reducing the occurrence of mixing and interference phenomena, and improving the overall aesthetics and safety.

[0021] The close fit between the cover plate and the cable bridge and the closed design inside the channel effectively prevent external factors such as dust and moisture from damaging the cables, and extend the service life of the cables. Description of the Drawings

[0030] In order to make the objectives, technical solutions and advantages of the embodiments of the present application clearer, the technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present application. Obviously, the described embodiments are part of the embodiments of the present application, rather than all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present application.

[0031] The embodiment of the present application provides a power supply line protection device for a substation, which can solve the problem that in the related art, the existing trough-type bridge usually adopts a single cover plate design, and in a complex environment such as a substation, the disassembly process of the cover plate is cumbersome, affecting the work efficiency.

[0032] Please refer to Figures 1 - 3 , a power supply line protection device for a substation includes; a bridge 1, a plurality of cross beams 3 and a plurality of cover plates 4. The bridge 1 has a channel 2 for accommodating cables inside; the plurality of cross beams 3 are sequentially arranged above the bridge 1; the cover plates 4 are arranged between two adjacent cross beams 3, and the cover plates 4 are attached to the top of the bridge 1; a plurality of connecting pieces 5 are arranged at the bottom of the cover plates 4, and installation grooves 6 adapted to the connecting pieces 5 are opened above the bridge 1; a plurality of baffles 7 are detachably arranged inside the channel 2, and the baffles 7 are used to divide the channel 2 into a plurality of chambers for accommodating cables.

[0033] The power supply line protection device realizes effective protection, convenient maintenance and orderly management of the power supply line. Its working principle is mainly reflected in the following aspects:

[0034] Bridge and cable tray design: The bridge 1 is the main structure of the entire device, and the cable tray 2 opened inside it provides a safe passage space for the cables. The design of the cable tray takes into account both the cable accommodation capacity and is convenient for subsequent maintenance and management.

[0035] Installation of crossbeams and covers: A number of crossbeams 3 are sequentially arranged above the bridge 1. These crossbeams not only play a supporting role but also provide a reference for the installation of the cover 4. The cover 4 is cleverly arranged between two adjacent crossbeams 3 and is connected to the installation groove 6 above the bridge 1 through the connecting piece 5 at its bottom. This design enables the cover 4 to fit firmly above the bridge 1, achieving the closed protection of the cable tray 2.

[0036] Detachability of the cover: Since the cover 4 is connected to the installation groove 6 of the bridge 1 through the connecting piece 5, in actual operation, the cover 4 can be conveniently detached and installed. This detachable design greatly improves the convenience of cable maintenance and repair, eliminating the need to disassemble the cover as a whole like traditional bridges.

[0037] Baffle separation function: The baffle 7 can separate the cable tray 2 according to actual needs, forming multiple independent chambers for accommodating cables. In this way, different types or functions of cables can be separated in an orderly manner, which not only facilitates management but also effectively reduces potential problems such as electromagnetic interference.

[0038] The detachable cover 4 design makes the cable maintenance and repair work more convenient and efficient. Instead of disassembling the cover as a whole, only a partial opening is required to complete the maintenance task, greatly saving time and labor costs.

[0039] The separation function of the baffle 7 makes the cable layout more orderly and reasonable. Different types or functions of cables are separated in different chambers, reducing the occurrence of mixing and interference phenomena, and improving the overall aesthetics and safety.

[0040] The close fit between the cover 4 and the bridge 1 and the closed design inside the cable tray effectively prevent external factors such as dust and moisture from damaging the cables, extending the service life of the cables.

[0041] The device can be flexibly configured and adjusted according to actual needs. Whether it is the number of crossbeams, the size of the cover or the separation method of the baffle can be customized according to specific circumstances to meet the power supply line protection requirements of different substations.

[0042] The bridge 1 in this implementation plan is U-shaped, and both ends of the channel 2 are open.

[0043] Both the bridge 1 and the cover plate 4 in this implementation plan are made of stainless steel.

[0044] Both the bridge 1 and the cover plate 4 are made of stainless steel, and this choice has many advantages. First of all, stainless steel has excellent corrosion resistance and can resist the erosion of corrosive substances such as moisture, salt, acid, and alkali in the environment, thereby extending the service life of the equipment. Secondly, the stainless steel material has high strength and hardness and can withstand large mechanical stresses and impacts, ensuring the stability and safety of the bridge 1 and the cover plate 4 during long-term use. In addition, stainless steel also has good aesthetics and easy cleaning properties, which can keep the surface of the equipment clean and shiny and improve the overall visual effect.

[0045] Preferably, in this implementation plan, the connector 5 includes a fixed block 51 and a permanent magnet 52 that are connected to each other. Both the fixed block 51 and the permanent magnet 52 are inserted into the installation groove 6, and one end of the fixed block 51 is connected to the cover plate 4.

[0046] The connector 5 is composed of two parts, the fixed block 51 and the permanent magnet 52, which are connected to each other. One end of the fixed block 51 is firmly connected to the cover plate 4 to ensure the stability of the cover plate 4; the other end is connected to the permanent magnet 52 and they are jointly inserted into the installation groove 6 above the bridge 1.

[0047] The permanent magnet 52 utilizes its strong magnetic properties to achieve a firm connection between the connector 5 and the installation groove 6. This magnetic connection method not only simplifies the installation process but also makes the disassembly and installation of the cover plate 4 more convenient and rapid.

[0048] Adopting the magnetic connection between the permanent magnet 52 and the installation groove 6 makes the installation and disassembly process of the cover plate 4 faster and simpler. Without the need to use additional tools or complex operation steps, the installation and disassembly of the cover plate can be easily completed, improving work efficiency.

[0049] Due to the adoption of the magnetic connection method, the use of traditional mechanical connectors such as screws and nuts is reduced, thereby reducing the maintenance cost. At the same time, the magnetic connectors are not easily worn or damaged, extending the service life and further reducing the long-term maintenance cost.

[0050] Furthermore, in this implementation plan, two handles 8 are oppositely arranged above the cover plate 4.

[0051] The design of having two grips 8 arranged oppositely above the cover plate 4 is for the consideration of improving operation convenience and safety. The grips 8 are usually designed in an ergonomic shape and size for easy holding by the operator. They are installed on both sides of the cover plate 4, opposite and symmetrically positioned to ensure stable support and balance during operation.

[0052] In one embodiment, the baffle 7 includes a horizontal plate 71 and a slider 72 connected to each other. A plurality of clamping grooves are provided inside the channel 2, and the slider 72 is inserted into the clamping grooves. The top of the horizontal plate 71 is in contact with the cover plate 4.

[0053] The horizontal plate 71, as the main part of the baffle 7, mainly functions to divide the space inside the channel 2 to form multiple independent chambers for accommodating cables. The top of the horizontal plate 71 is in contact with the cover plate 4, ensuring the stability of the baffle 7 after installation and preventing cables from spilling out of the divided area.

[0054] The slider 72 is another important part of the baffle 7. It is connected to the horizontal plate 71 and inserted into the clamping grooves provided inside the channel 2. This insertion method makes the installation and disassembly of the baffle 7 very simple. The operator only needs to align the slider 72 with the clamping groove and gently push it in to complete the installation; when disassembly is needed, just gently pull out the slider 72.

[0055] By adjusting the number and position of the baffles 7, the space inside the channel 2 can be flexibly divided to form multiple independent cable chambers. This division method helps to reduce interference and confusion between cables and improve the efficiency of cable management.

[0056] The number and position of the clamping grooves can be adjusted as needed to adapt to different numbers and arrangements of the baffles 7. This design makes the baffle 7 in this embodiment have strong adaptability and flexibility and can meet the cable management requirements in different scenarios.

[0057] As a preferred embodiment, the baffle 7 includes arc-shaped blocks 73 arranged oppositely on both sides of the horizontal plate 71. The bottom of the arc-shaped blocks 73 is in contact with the bottom of the channel 2, and obtuse angles are provided at both ends of the bottom of the channel 2.

[0058] The design of the baffle 7 is further optimized, especially by adding arc-shaped blocks 73 on both sides of the horizontal plate 71. This improvement not only enhances the stability of the baffle 7 but also strengthens its adaptability and sealing performance with the channel 2. The bottom of the arc-shaped blocks 73 is in contact with the bottom contour of the channel 2, enabling the arc-shaped blocks 73 to better fit the bottom of the channel when inserted into the channel 2, reducing the shaking or loosening caused by gaps. At the same time, the bottom of the arc-shaped blocks 73 is in close contact with the bottom of the channel 2, further enhancing the stability of the baffle 7.

[0059] The arc block 73 is a part of the baffle 7, and its arc design cleverly conforms to the natural bending shape of the cable. When the cable is placed inside the chamber, the curved surface of the arc block 73 can guide the cable to transition smoothly, avoiding direct collision between the cable and the baffle and scratching by sharp edges.

[0060] At the same time, compared with acute angles or right angles, the obtuse angles at both ends of the bottom of the groove 2 provide a larger contact area and a smoother transition when the cable contacts the bottom of the groove. This design reduces the friction and shear force generated by the cable and the bottom of the groove when the cable moves or adjusts its position, thereby further protecting the integrity of the cable. In addition, the obtuse angle design also helps to disperse the pressure of the cable on the bottom of the groove, reducing the risk of deformation or damage to the groove due to long-term stress.

[0061] In another embodiment, a cable holder 9 is further included, wherein a slider 2 adapted to the slot is disposed at the bottom of the cable holder 9, the cable holder 9 has a receiving slot 91 for receiving the cable, and the two ends of the top of the cable holder 9 are made of elastic material. The two ends of the receiving slot are open.

[0062] In this embodiment, a cable holder 9 is introduced as an important component for cable management. The cable holder 9 is designed to provide a more flexible and convenient cable fixing method to further improve the overall performance and maintainability of the substation power supply line protection device.

[0063] The bottom of the cable clamp 9 is provided with a slider 2 adapted to the slot, so that the cable clamp 9 can be installed in the channel 2 quickly and firmly through the plug-in mode of the slider and the slot, just like the baffle 7 .

[0064] The cable holder 9 is provided with a receiving groove 91 for receiving the cable. The shape and size of the receiving groove 91 can be customized according to the diameter and number of the cables to ensure that the cables can be firmly placed therein. At the same time, the design of the receiving groove 91 also takes into account the bending radius and heat dissipation requirements of the cables to ensure that the cables are not damaged during the fixing process and maintain a good operating state.

[0065] The top ends of the cable holder 9 are made of elastic material. This design enables the cable holder 9 to produce a certain deformation and buffering effect when subjected to external force, thereby protecting the cable from being squeezed or damaged. At the same time, the elastic material top also helps to simplify the insertion and removal process of the cable, making it convenient to press the cable into the receiving groove 91, thereby improving the operating efficiency.

[0066] Both ends of the receiving groove 91 are designed to be open. This design allows the cable to easily enter or leave the receiving groove 91 from the opening without complicated operation steps or tools. At the same time, the open design also helps to reduce the friction and resistance of the cable during the fixing process, thereby improving the fixing effect.

[0067] Furthermore, it should be noted that in this implementation scheme, a number of connection holes are provided at both ends of the cable tray 1, and the two cable trays are connected through the connection holes and external connection pieces.

[0068] In order to achieve a stable connection between the cable trays 1, in this implementation scheme, a combination of connection holes and external connection pieces is adopted. Specifically, a number of connection holes are provided at both ends of the cable tray 1. The designed positions, quantities, and hole diameters of these connection holes have all been precisely calculated to ensure the connection strength and stability between the cable trays.

[0069] When connecting two cable trays, a dedicated external connection piece can be used. The external connection piece usually has bolt holes or hook structures that match the connection holes of the cable tray. The operator only needs to place the external connection piece between the cable trays to be connected and pass the bolts or hooks through the connection holes for fastening. This connection method is not only simple and fast to operate, but also has high connection strength and reliability. By reasonably arranging the positions of the connection holes and external connection pieces, horizontal, vertical, or inclined connections between the cable trays can also be achieved to meet the installation requirements in different scenarios.

[0070] Furthermore, it should be noted that in this implementation scheme, one end of the channel 2 is connected to the ventilation duct of the external central air conditioner, and a filter screen is provided at the other end.

[0071] The channel 2 is not only limited to the accommodation and management of cables, but also incorporates considerations for ventilation and heat dissipation. Specifically, one end of the channel 2 is connected to the ventilation duct of the external central air conditioner. This design allows the cold or hot air generated by the central air conditioner to be directly conveyed into the channel, thereby effectively regulating the temperature of the cables inside the channel. In summer, the cold air can reduce the temperature inside the channel and prevent the cables from aging or being damaged due to high temperature. In addition, this ventilation design also helps to reduce the humidity inside the channel, further protecting the cables from the influence of a humid environment.

[0072] A filter screen is provided at the other end of the channel 2. The main function of the filter screen is to prevent sundries such as dust and insects from entering the inside of the channel, ensuring the unobstructed ventilation duct and the cleanliness inside the channel. Through the filtering effect of the filter screen, the amount of dust adhering to the cables can be reduced, and the risks of poor heat dissipation and short circuits caused by dust accumulation can be lowered.
