Description

Technical Field

[0001] The utility model relates to the technical field of photovoltaics, and more specifically, to a photovoltaic box. Background Art

[0002] In the application field of photovoltaic boxes, although significant progress has been made in current technical practices, a kind of photovoltaic box transformer proposed in the Chinese utility model patent application number: CN201820664268.9, includes a box body, the box body includes a first side plate, a second side plate, a third side plate and a fourth side plate, the first side plate, the second side plate, the third side plate and the fourth side plate surround to form a high-voltage chamber, a low-voltage chamber and a transformer chamber, the transformer chamber is arranged between the high-voltage chamber and the low-voltage chamber, the first side plate and the third side plate are arranged opposite to each other, the second side plate and the fourth side plate are arranged opposite to each other, and it is characterized in that: a transformer is installed in the transformer chamber, the transformer chamber is provided with a protective net and a protective door, the protective door opens towards the low-voltage chamber side, a low-voltage chamber cabinet door for opening the low-voltage chamber is arranged on the first side plate, a high-voltage chamber cabinet door for opening the high-voltage chamber is arranged on the third side plate, and a ventilation device is arranged at the position of the fourth side plate corresponding to the transformer chamber. The utility model has a good heat dissipation effect.

[0003] There are still some deficiencies in the existing photovoltaic boxes during use that need to be improved. The primary problem lies in the fixing mechanism of wire terminals. Traditionally, wire terminals are fastened by bolts. This fixing method is particularly inconvenient when dealing with diverse and differently lengthed wire connections because it cannot flexibly adapt to the position requirements of different connection points. It cannot slide-adjust according to the different lengths of different wires and the different connection positions of the wire terminals. Secondly, the bolt fixing method commonly used for installing components inside the photovoltaic box is not only cumbersome and time-consuming but also increases the difficulty of replacing or adjusting components during maintenance. Moreover, regarding the problem of chaotic wire management, existing photovoltaic boxes often lack effective wire combing and fixing devices. The disorderly arrangement of wires inside the box not only affects the aesthetics but may also lead to performance degradation or even failures due to mutual entanglement or extrusion. Therefore, we make improvements and propose a photovoltaic box. Summary of the Utility Model
