Description

Technical Field

[0001] This utility model relates to the field of building construction technology, and in particular to a centralized junction box assembly. Background Technology

[0002] Combiner boxes play a central role in solar photovoltaic systems, collecting and transmitting the direct current (DC) generated by multiple solar panels to the inverter, simplifying the system structure and improving power transmission efficiency. Simultaneously, the overcurrent protection devices built into the combiner box, such as fuses or circuit breakers, effectively prevent electrical faults and ensure system safety. Furthermore, they also feature lightning and surge protection, shielding the system from extreme weather conditions. Some combiner boxes are also equipped with data acquisition modules, allowing real-time monitoring of the power station's operating status and enabling remote maintenance, further enhancing system reliability and ease of maintenance.

[0003] As photovoltaic power plants grow larger, the size of combiner boxes also increases, requiring the collection of more cables. Traditional combiner boxes are directly installed on the poles, which is difficult to install and the poles have poor stability. Utility Model Content

[0004] The purpose of this utility model is to overcome the defects of the prior art, provide a centralized combiner box assembly, which facilitates the installation of the combiner box and improves the connection stability of the combiner box.

[0006] Two columns are arranged horizontally at intervals;

[0007] Two horizontal bars are arranged vertically at intervals, and their two ends are respectively connected to the two columns;

[0008] The combiner box is connected to the upper crossbar, and the bottom of the combiner box has a cable inlet for cable insertion.

[0009] A limiting bracket for preventing cables from being inserted into the inlet in a sequential manner is located below the combiner box and connected to the lower crossbar.

[0010] A further improvement of this utility model's centralized combiner box assembly is that the tops of both columns are higher than the upper crossbar, and the upper crossbar and the tops of both columns are connected by diagonal bracing.

[0011] A further improvement of this utility model's centralized combiner box assembly is that the limiting frame includes:

[0012] A base plate, which is connected to a lower crossbar;

[0013] A strip plate, the strip plate being connected laterally to the base plate;

[0014] Multiple inverted U-shaped clips are provided for one-to-one cable threading, and the multiple inverted U-shaped clips are spaced apart along the length direction of the strip plate.

[0015] A further improvement of this utility model's centralized combiner box assembly is that the limiting frame further includes a wire separating grid for separating the red and black wires of the cable, the wire separating grid comprising:

[0016] Multiple vertical rods are arranged at horizontal intervals, and each vertical rod is vertically connected to the base plate;

[0017] A stop bar is connected in series at the top of multiple vertical bars, and a threading channel is formed between adjacent vertical bars for a red or black wire to pass through.

[0018] A further improvement of this utility model's centralized combiner box assembly is that a cover plate for protecting cables is also connected to the base plate. The cover plate is detachably connected to the base plate, and a space for cables to pass through is formed between the cover plate and the base plate. A through hole for cable insertion is provided at the bottom of the cover plate.

[0019] A further improvement of this utility model's centralized combiner box assembly is that the base plate and the lower crossbar are connected by a mesh frame.

[0020] Compared with the prior art, the advantages of this utility model are:

[0021] 1. By setting up tie rods, an upward pulling force is always provided to the upper crossbar to counteract the weight of the junction box and ensure structural stability.

[0022] 2. Each cable is limited by a limit bracket. In addition, the red and black wires of the cable are separated and straightened to facilitate subsequent maintenance or removal. Attached Figure Description

[0033] Combiner box 3 is connected to the upper crossbar 2, and the bottom of the combiner box 3 is reserved with an inlet for inserting cable 6;

[0034] A limiting bracket 5 is used to limit the insertion of cables 6 into the inlet in a one-by-one manner. The limiting bracket 5 is located below the junction box 3 and connected to the lower crossbar 2.

[0035] By connecting the junction box 3 and the limiting frame 5 to different crossbars 2, the gravity load is shared, thus improving the structural stability.

[0044] Specifically, the bottom end of each inverted U-shaped buckle extends outward and forms a connecting plate, which is connected to the strip plate 503 by a fifth bolt.

[0045] Pass cable 6 through the corresponding inverted U-shaped buckle, then adjust the tightness of the fifth bolt to lock the inverted U-shaped buckle, thus limiting the position of cable 6.

[0050] Preferably, the base plate 502 is also connected to a cover plate for protecting the cable 6. The cover plate is detachably connected to the base plate 502, and a space is formed between the cover plate and the base plate 502 for the cable 6 to pass through. The bottom of the cover plate has a through hole for the cable 6 to be inserted.

[0051] By installing this cover, cable 6 is protected from the influence of the external environment, thus improving the service life of cable 6.

[0052] Specifically, the cover plate is connected to the base plate 502 by a fourth bolt.

[0053] Preferably, the base plate 502 is connected to the lower crossbar 2 by a mesh frame 501.

[0055] Specifically, the grid frame 501 is connected to the lower crossbar 2 by a third bolt.
