Description

Technical Field

[0001] The utility model belongs to the technical field of photovoltaic solar panels and relates to a photovoltaic solar panel connecting cable. Background Art

[0002] Photovoltaic solar panels are devices used to convert sunlight into electrical energy. The basic working principle is to use the photovoltaic effect to directly convert solar radiation into direct current for use by loads or store in batteries, and transmit the electrical energy to other electrical equipment through photovoltaic solar panel connection cables. If the photovoltaic solar panel connection cables cannot be protected from bending and damage, it may cause a series of problems, affect the normal operation of the entire solar energy system, and may even cause safety accidents.

[0003] First, cable bending and damage will lead to a decrease in power transmission efficiency. The power generated by solar panels is transmitted to other devices or the power grid through cables. If the cables are bent and damaged, the resistance will increase, resulting in a decrease in transmission efficiency, loss of some power, and reduced utilization of solar energy.

[0004] Secondly, cable bend damage may cause short circuit or open circuit. If the insulation layer of the cable is damaged or the conductor is broken at the bend, it may cause a short circuit or open circuit, affecting the normal operation of the equipment. In the case of a short circuit, the current directly passes through the conductor at the bend, which may burn the cable and related equipment; in the case of an open circuit, the current cannot pass and the equipment cannot work normally.

[0005] Thirdly, cable bending damage may cause safety accidents. If the cable is exposed after being damaged at the bend, it may cause electric shock accidents. Especially in a humid environment, damaged cables are more likely to cause electric shock accidents. In addition, if solar panels or other equipment fail during operation due to cable bending damage, it may cause safety accidents such as fire.

[0006] Finally, cable bend damage will increase maintenance costs. Solar panels and other equipment require regular inspection and maintenance. If cable bend damage is found, it needs to be replaced or repaired, which will increase maintenance costs. If the bend damage is severe or occurs multiple times, it may be necessary to replace the entire cable or solar system component, which is more expensive.

[0007] Therefore, effective protective measures should be taken to prevent the photovoltaic solar panel connecting cable from bending and damage to ensure the normal operation and safety of the solar energy system. Therefore, a photovoltaic solar panel connecting cable is urgently needed to solve the above problems. Utility Model Content
