Description

Technical Field

[0001] The utility model relates to the technical field of cables, in particular to an anti-aging cable dedicated to photovoltaics. Background Art

[0002] Photovoltaic, or photovoltaic power generation system, is a power generation system that uses the photovoltaic effect of semiconductor materials to convert solar radiation energy into electrical energy. The energy of the photovoltaic power generation system comes from inexhaustible solar energy, which is a clean, safe and renewable energy source. The photovoltaic power generation process does not pollute the environment or damage the ecology. Photovoltaic power generation systems are divided into independent photovoltaic systems and grid-connected photovoltaic systems. Photovoltaic power generation systems are composed of solar cell arrays, battery packs, charge and discharge controllers, inverters, AC distribution cabinets, solar tracking control systems and other equipment.

[0003] Usually, it is a rope-like cable made of several or several groups of wires (at least two in each group), each group of wires is insulated from each other and often twisted around a center, and the entire outside is covered with a highly insulating covering. The cable has the characteristics of internal power supply and external insulation.

[0004] Photovoltaic power generation systems are usually installed in large open areas such as mountains and lakes. Cables are needed to transmit and store electricity during power generation. Since the cables are laid in the soil or water for a long time, the outer surface of the cables is more prone to aging and cracking, which in turn affects their use. Therefore, we propose a photovoltaic-specific anti-aging cable. Utility Model Content

[0005] The purpose of the utility model is to solve the shortcomings existing in the prior art. Photovoltaic power generation systems are usually installed in large open areas such as mountains and lakes. Cables are needed to transmit and store electricity during power generation.

[0009] As a preferred solution of the utility model, the protection structure also includes a first protective layer, the first protective layer is wrapped around the outer surfaces of the multiple battery cells and the rubber sleeve, and the first protective layer is made of polyvinyl chloride.

[0010] The technical effect of adopting the above further scheme is that polyvinyl chloride has strong chemical corrosion resistance and good corrosion resistance to chemical substances such as acid, alkali, salt, oil, etc., and is suitable for use in various environmental conditions.

[0011] As a preferred solution of the utility model, the outer layer of the first protective layer is further wrapped with a second protective layer, and the second protective layer is made of polytetrafluoroethylene.

[0012] The technical effect of adopting the above further scheme is that polytetrafluoroethylene has good friction and wear resistance, can work stably under high speed, high temperature and high pressure conditions, and has high tensile strength.

[0013] As a preferred solution of the utility model, the outer layer of the second protective layer is also wrapped with a third protective layer and an outer surface layer. The third protective layer is made of polypropylene and is used to protect the internal battery core in a polyacidic and alkaline environment. The outer surface layer is made of polytetrafluoroethylene.

[0014] The technical effect of adopting the above further scheme is: polypropylene has good chemical properties, does not absorb water, does not react with most chemicals, and has high stability, while polytetrafluoroethylene is resistant to high temperatures and strong in acid and alkali resistance. The combination of the two as the outermost layer has good anti-aging, acid and alkali resistance and stability.
