1. The present utility model relates to the technical field of photovoltaic power generation, in particular, to a novel photovoltaic cable junction box device.Background technique:2. Photovoltaic power generation technology has become more and more popular nowadays. Large-scale photovoltaic modules
2. Inventory of photovoltaic high current junction box requirements From the electrical performance parameters of typical high-current modules of photovoltaic module factories and the selection of rated current of junction boxes, it can be seen that the M10 module with a current of 13.9A adopts the mature single-core solution in the industry and has sufficient safety margin, and uses diodes of higher specifications. The reliability of the high-current junction box is guaranteed. The 18.4A G12 ultra-high current module adopts a new dual-core solution (not verified by the industry), and the safety margin of the double-sided module is too small.
In a photovoltaic power station, to gather the power of a large number of components together and enter the inverter, it must rely on cables and connectors. The photovoltaic connector is one of the components, combiner boxes, controllers, and inverters in the photovoltaic power generation system.
How to ensure the quality and safety of photovoltaic connector parts under the general trend? In recent years, with the rapid development of the photovoltaic industry, how to increase power generation and reduce power generation costs on the premise of ensuring long-term stable and safe operation has become a difficult problem for the photovoltaic industry. The photovoltaic industry is constantly developing, and photovoltaic technology and photovoltaic products are also advancing with the times, constantly adapting to the requirements of the development of the entire market. But no matter how it changes, quality will be our common goal.
Under the background of realizing the "dual carbon goal", it is expected that in the next five years, my country's annual new installed capacity of photovoltaics will reach 62 to 68GW, and the cumulative installed capacity of China's photovoltaic power plants will reach 561GW in 2025. In the process
