Description

Technical Field

[0001] This utility model relates to the field of power equipment technology, and in particular to a bird protection device for capacitor towers in converter stations. Background Technology

[0002] With the improvement of the ecological environment, the living conditions for birds have been greatly improved, and their numbers are gradually increasing while their range of activity is also expanding. Statistical data shows that bird damage is one of the major hazards threatening the safe operation of power grids. In China, bird-related faults have become the second most common type of transmission line fault.

[0003] Converter stations are often located in remote areas with frequent bird activity and are often open structures, making them highly susceptible to bird damage. If a bird lands inside the capacitor tower, short circuits are highly likely to occur between capacitor terminals and tower layers, triggering the unbalanced current protection of the capacitor tower and causing the filter to trip. If the filter bank fails to meet the absolute minimum filter requirements at this time, the DC system power will decrease, causing load loss and potentially even DC blocking, jeopardizing the operation of the capacitor bank and affecting the effective and safe operation of the power grid.

[0004] However, currently, one method to prevent bird damage to capacitor towers in converter stations is to spray insulating materials. However, this method is not only time-consuming and labor-intensive but also ineffective. It may also affect the heat dissipation of capacitors and reduce their service life. Utility Model Content

[0020] The present invention will be further described in detail below with reference to the accompanying drawings.

[0021] Reference Figure 1 and Figure 2 This utility model discloses a bird protection device 1 for converter station capacitor towers, comprising a cuboid frame and a mesh composite insulator 10. The top of the cuboid frame is connected to the upper platform 21 of the converter station capacitor tower 2, and the bottom of the cuboid frame is connected to the lower platform 22 of the converter station capacitor tower 2. The mesh composite insulator 10 is arranged around the outer peripheral wall of the cuboid frame to cover the interlayer of the converter station capacitor tower 2. The mesh composite insulator 10 is made of composite material. This arrangement protects the converter station capacitor tower 2, preventing birds from entering the capacitor tower, while not affecting the heat dissipation and service life of the converter station capacitor tower 2.

[0022] The composite material includes a core material and an adhesive. The core material is any one of glass fiber, aramid, polyester, and nylon, and the adhesive is any one of high-temperature silicone rubber, epoxy resin, and polyurethane.

[0023] When glass fiber is used as the core material in composite materials, it is woven into a fabric-like structure using fine weaving techniques. The interweaving density and uniformity between fibers are strictly controlled to construct a stable basic framework for the board. Glass fiber possesses tensile, bending, and compressive strength, greatly enhancing the overall mechanical properties of the composite material. The excellent chemical stability of glass fiber allows the composite material to effectively resist the erosion of acids, alkalis, moisture, and various organic solvents, thus significantly extending its service life and durability. Furthermore, glass fiber gives the composite material higher stiffness, maintaining a more stable shape even under external forces, reducing deformation. High-temperature silicone rubber is then selected as the binder. High-temperature silicone rubber enhances the toughness of the composite material, possesses strong anti-flashover capabilities and unique hydrophobic migration properties, and also exhibits corrosion resistance and weather resistance. This makes the composite material less prone to breakage and protects the glass fiber from environmental erosion, thereby extending the service life of the composite material.

[0024] Furthermore, in this embodiment, the outer surface of the mesh composite insulator 10 is coated with an RTV coating, thereby enhancing the weather resistance of the mesh composite insulator 10.

[0025] Among them, the insulation and electrical properties of the composite material enable the mesh composite insulator 10 to withstand the voltage difference between the capacitor towers 2 of the converter station.

[0026] Furthermore, in this embodiment of the present invention, the mesh composite insulator 10 includes multiple insulating cylindrical strips, all of which are arranged around a cuboid frame. The multiple insulating cylindrical strips are spaced apart along the height direction of the cuboid frame, and there is a preset distance between each two adjacent insulating cylindrical strips.

[0027] Specifically, the method of wrapping an insulating cylindrical strip around the outer perimeter of the cuboid frame at preset intervals can be used to prevent birds from entering the bird protection device 1.

[0028] The preset distance ranges from 2cm to 4cm. In this embodiment, the preset distance is 2cm, and the method of wrapping the device around the bird at 2cm intervals can be used to prevent birds from entering the bird protection device 1, achieving a good bird-proofing effect.

[0029] Specifically, the diameter of the insulating cylindrical strip cross-section ranges from 4mm to 6mm. In this embodiment, the diameter of the insulating cylindrical strip cross-section is 4mm.

[0030] Multiple insulating cylindrical strips are laid from the top to the bottom of the cuboid frame, with one insulating cylindrical strip horizontally wrapped around the cuboid frame every 2cm, and the insulating cylindrical strips are tightly connected to the cuboid frame.

[0031] Furthermore, in this embodiment, the cuboid frame includes at least four insulating support columns 20, which are arranged in a cuboid shape. The top ends of the four insulating support columns 20 are all connected to the upper frame 21, and the bottom ends of the four insulating support columns 20 are all connected to the lower frame 22.

[0032] Specifically, the center lines of the four insulating support columns are set in parallel, and the top and bottom ends of the insulating support columns 20 are welded to the upper frame 21 and the lower frame 22, respectively.

[0033] like Figure 1 As shown, in this embodiment, there are 4 insulating support columns 20. Of course, the number of insulating support columns 20 can also be 5 or 6.

[0034] During use, the top and bottom of the four insulating support columns 20 are welded to the upper frame 21 and lower frame 22 of the converter station capacitor tower 2, respectively, and the mesh composite insulator 10 is placed around the cuboid frame, thereby covering the interlayer of the converter station capacitor tower 2 with the mesh composite insulator 10 and protecting the capacitor tower.

[0035] Continue to refer to Figure 3 and Figure 4 The mesh composite insulator 10 can also adopt a mesh structure; this setting makes its windproof performance better than other solid insulators; at the same time, it effectively avoids the accumulation of moisture and heat, thereby keeping the space ventilated and dry.

[0036] The mesh composite insulator 10 of the grid structure includes multiple horizontal composite cylindrical strips and multiple vertical composite cylindrical strips. The multiple horizontally arranged horizontal composite cylindrical strips and the multiple vertically arranged vertical composite cylindrical strips intersect, and the intersection of the horizontal composite cylindrical strips and the vertical composite cylindrical strips constitutes the node of the grid structure.

[0037] Among them, the larger and more sparsely arranged the holes on the mesh composite insulator 10, the better the ventilation. However, the holes should not be too large, otherwise they will not be able to effectively prevent birds. At the same time, they should not be too small, as small holes will easily accumulate snow on the surface of the mesh composite insulator 10, affecting its insulation performance.

[0038] The size of the hole is determined according to the actual situation, and this embodiment does not impose any restrictions on it.

[0039] It should be noted that the composite insulator with this grid structure can be used alone without a cuboid frame. When used alone, it can be directly installed around the outer perimeter of the converter station capacitor tower 2 for bird protection. When used alone, the composite insulator with this grid structure can also be used for bird protection of other outdoor equipment.

[0040] When used alone for bird protection on capacitor tower 2 of the converter station, the composite insulator with this mesh structure is installed around the outer surface of capacitor tower 2 to protect the space between the tower layers. Due to its unique mesh structure, birds cannot penetrate into the interior of the capacitor tower, effectively preventing filter tripping caused by birds falling into the tower. Simultaneously, the insulator's effective insulation allows it to withstand voltage differences between capacitor towers, thus enabling normal operation between towers.

[0041] The bird protection device 1 for converter station capacitor towers provided in this application includes a cuboid frame and a mesh composite insulator 10. The top of the cuboid frame is connected to the upper frame 21 of the converter station capacitor tower 2, and the bottom of the cuboid frame is connected to the lower frame 22 of the converter station capacitor tower 2. The mesh composite insulator 10 is arranged around the outer perimeter wall of the cuboid frame to cover the interlayer of the converter station capacitor tower 2. This arrangement protects the converter station capacitor tower 2, preventing birds from entering the capacitor tower, while not affecting the heat dissipation and service life of the converter station capacitor tower 2.

[0042] It should be noted that, in this document, relational terms such as "first" and "second" are used merely to distinguish one entity or operation from another, and do not necessarily require or imply any such actual relationship or order between these entities or operations. Furthermore, the terms "comprising," "including," or any other variations thereof are intended to cover non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements includes not only those elements but also other elements not expressly listed, or elements inherent to such a process, method, article, or apparatus. Without further limitation, an element defined by the phrase "comprising one..." does not exclude the presence of other identical elements in the process, method, article, or apparatus that includes said element.

[0043] Finally, it should be noted that the above embodiments are merely examples for clearly illustrating the present invention and are not intended to limit the implementation. Those skilled in the art can make other variations or modifications based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations. However, obvious variations or modifications derived therefrom are still within the protection scope of this invention.
