Technical Field
[0001] This utility model relates to the field of cable technology, specifically to a low-smoke halogen-free control flexible cable for photovoltaic power generation systems. Background Technology
[0002] Photovoltaic power generation is an important way to utilize renewable energy. Its power generation facilities are usually deployed in vast outdoor environments, such as deserts, mountains, and grasslands. These power generation facilities are connected together by cables.
[0003] In photovoltaic power generation systems, cables are key components connecting photovoltaic modules, inverters, and power distribution equipment. Once the cables are damaged, the power transmission of the entire system will be affected, and in severe cases, the photovoltaic modules may even fail to generate electricity normally, thereby affecting the operating efficiency and stability of the entire photovoltaic power generation system.
[0004] Due to the complex natural environment in these areas, cables often face attacks from various wild animals during installation and use, especially rodents such as rats. These rodents often gnaw on cables laid in the wild, which not only damages the outer protective layer of the cable but may also damage the internal conductors, thus affecting the normal operation of the cable and causing the power generation equipment to fail to generate electricity. This, in turn, affects the operating efficiency and stability of the entire photovoltaic power generation system. Utility Model Content

[0023] It should be noted that, unless otherwise specified, the embodiments and features described in this application can be combined with each other. This application will now be described in detail with reference to the accompanying drawings and embodiments.
[0024] To enable those skilled in the art to better understand the present application, the technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present application, and not all embodiments. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative effort should fall within the scope of protection of the present application.
[0025] like Figure 1-4 As shown, this application provides a low-smoke halogen-free control flexible cable for a photovoltaic power generation system, including: a conductor 1, a support assembly on the conductor 1, the support assembly including a support steel cable 2 disposed inside the conductor 1, and a protective layer 5 disposed outside the conductor 1, the support assembly being used to support the conductor 1.
[0026] Specifically, such as Figure 1 As shown, the support assembly also includes a flame-retardant layer 4 disposed on the outside of the conductor 1. The flame-retardant layer 4 is made of cross-linked polyethylene, which has low smoke and halogen-free characteristics when burning. The flame-retardant layer 4 can prevent the fire from becoming too large when the device catches fire, and can reduce the harm to the surrounding environment and personnel.
[0027] Specifically, such as Figure 1 As shown, a first filler 3 is provided between the wire 1 and the flame-retardant layer 4. The first filler 3 is made of aluminum hydroxide, which can absorb a large amount of heat, thereby achieving a flame-retardant effect and further reducing the spread of fire.
[0028] Specifically, such as Figure 1 As shown, a shielding layer 6 is provided outside the flame retardant layer 4. The shielding layer 6 is made of copper foil, which can effectively limit the electromagnetic field inside the cable to a certain range and prevent interference to the outside world.
[0029] Specifically, such as Figure 1 As shown, the protective layer 5 is set on the outside of the shielding layer 6. The protective layer 5 is made of rubber and can prevent heavy objects from damaging the wire 1.
[0030] The protective layer 5 is provided with a protective component, which includes a metal mesh 10 disposed outside the protective layer 5, an outer skin 8 disposed outside the metal mesh 10, and a cone-shaped block 11 disposed outside the outer skin 8. The protective component is used to prevent animals from biting.
[0031] Specifically, such as Figure 3 As shown, the protective component also includes a fixing block 9 in the middle of the surface of the protective layer 5, and connecting plates 12 on both sides of the fixing block 9. Both sets of connecting plates 12 are provided with placement grooves 14. Through the protective layer 5, the metal mesh 10 can be quickly fixed during production.
[0032] Specifically, such as Figure 3 As shown, a pressure block 13 is provided on the outer skin 8 corresponding to the placement groove 14. The pressure block 13 is movably disposed in the placement groove 14. The metal mesh 10 is disposed between the pressure block 13 and the placement groove 14. A second filler 7 is disposed outside the metal mesh 10, and the second filler 7 is located between the outer skin 8 and the protective layer 5. The material of the second filler 7 is silicon dioxide. The second filler 7 can reduce the possibility of fire. The cooperation between the pressure block 13 and the placement groove 14 can realize the rapid fixation of the metal mesh 10.
[0033] Specifically, such as Figure 3 As shown, multiple sets of support columns 15 are provided on the outer side of the outer skin 8, and a cone-shaped block 11 is provided at the top of the support column 15. The cone-shaped block 11 can increase the difficulty for wild animals to gnaw and reduce the probability of wild animals gnawing.
[0034] In this embodiment: the supporting steel cable 2 increases the flexibility of the device, allowing it to bend and move in complex environments. The combination of the first filler 3 and the flame-retardant layer 4 reduces the spread of fire and the generation of toxic and harmful fumes in the event of an accidental fire. The combination of the metal mesh 10 and the cone-shaped block 11 reduces the probability of wild animals biting the device, thereby maximizing the protection of the device and enabling it to function normally.
[0035] Specifically, this solution is as follows: By installing supporting steel cables 2 inside multiple sets of conductors 1, the flexibility of the device can be improved. The first filler 3 between the multiple sets of conductors 1, in conjunction with the flame-retardant layer 4, can reduce the emission of toxic and harmful fumes in the event of an accidental fire, thus maximizing the protection of the surrounding environment and personnel. The protective layer 5 can prevent the conductors 1 from being broken when heavy objects fall. By connecting the metal mesh 10 to a power source, it can provide an electric shock to wild animals after they have been bitten, thus better protecting the device. Personnel can view the metal mesh 10 through a terminal, making it easy for them to promptly identify the parts of the device that have been bitten by wild animals and facilitate maintenance. The cooperation between the placement groove 14 and the pressure block 13 can fix the metal mesh 10 during production, facilitating production. The second filler 7 can prevent fires after the metal mesh 10 is connected to a power source, thus protecting the device. The cone-shaped block 11 can increase the difficulty for wild animals to bite, thereby reducing the probability of wild animals biting the device.
[0036] Those skilled in the art should understand that the discussion of any of the above embodiments is merely exemplary; within the framework of this invention, the technical features of the above embodiments or different embodiments can also be combined, the steps can be implemented in any order, and there are many other variations of the different aspects of this invention as described above, which are not provided in detail for the sake of brevity.
