Description

Technical Field

[0001] This utility model relates to the field of control cabinets, and in particular to a control cabinet suitable for outdoor circuit breakers. Background Technology

[0002] For electrical equipment, traditionally, control cabinets had pre-drilled square cable entry holes at the bottom. After the circuit breaker arrived at the construction site, the cables from the main unit to the control cabinet were laid and connected. After construction was completed, the control cabinet was sealed with cable sealant. However, this construction method requires on-site work. When our personnel lack the necessary permits for on-site work in foreign countries, on-site work cannot be carried out. Furthermore, it does not take into account protection during ventilation and heat dissipation, making it easy for foreign objects in the outside air to enter the control cabinet. Utility Model Content

[0021] Example 1

[0022] like Figures 1-7 As shown in the figure, the control cabinet for outdoor circuit breakers proposed in this embodiment includes a cabinet body 1, a cabinet door, and a ventilation assembly.

[0023] Cabinet 1 is made of 316 stainless steel with an IP66 protection rating and an overall powder-coated finish. Cabinet 1 has a left and right compartment, and multiple metal connector mounting holes 101 at the bottom for installing metal connectors. These holes can be adjusted according to the size of the metal connectors, cable specifications, and terminal block wiring positions to meet the needs of different projects. Cabinet 1 also has cable trays inside. Ventilation holes 102 are located on both sides of cabinet 1. Three rows of side beams 7 are arranged horizontally inside cabinet 1, and multiple rear beams 8 are located at the rear. Each row of side beams 7 has four beams, and five rear beams 8 are installed in both the left and right compartments. The side beams 7 and rear beams 8 are horizontally distributed and connected to cabinet 1 with bolts, effectively enhancing the structural strength of the entire control cabinet and preventing deformation. The side beams 7 and rear beams 8 also have mounting ports for installing components. A rain cover 6 is installed on the top of the cabinet 1. The rain cover 6 is connected to the cabinet 1 by bolts. The length and width of the rain cover 6 are larger than the length and width of the cabinet 1, respectively. A grounding copper busbar 9 is installed inside the left compartment and is connected to the cabinet 1 by bolts.

[0024] like Figure 4 As shown, multiple mounting brackets 10 are arranged side by side on the back of the cabinet 1. The mounting brackets 10 have an L-shaped structure and have connection holes at the ends for fixing the control cabinet to the existing mounting bracket. The L-shaped mounting brackets 10 have high strength and prevent deformation.

[0025] The cabinet includes two outer doors 2 for opening and closing the left and right compartments respectively, and an inner door 5 located inside the left compartment. The outer doors 2 are hinged to the cabinet body 1 via hinges 21 and are equipped with outer door locks. The two outer doors 2 are arranged in a double-opening configuration. The inner door 5 is hinged to the cabinet body 1 and is equipped with an inner door lock 51. The inner door 5 can be fitted with an operating handle, indicator lights, a counter, and has printed electrical main wiring diagrams. A glass window 4 is provided on the outer door 2 outside the left compartment, allowing the viewer to see the status of the components on the inner door 5.

[0026] like Figure 7 As shown, for ventilation of this control cabinet, two sets of ventilation components are used. These components are located outside the ventilation holes 102 on both sides of the cabinet 1, and include a ventilation hood 11 with its opening facing downwards, mounted on the cabinet 1, and multiple partitions 12 arranged side-by-side inside the ventilation hood 11. The downward-facing opening of the ventilation hood 11 blocks the ventilation holes 102 horizontally, providing initial protection. The multiple partitions 12 are staggered vertically to provide offset blocking of foreign objects in the outside air, providing secondary protection. Air inside the cabinet 1 can circulate through the ventilation holes 102 without hindering heat dissipation and ventilation.

[0027] In this embodiment, a metal connector is installed at the metal connector mounting hole 101 at the bottom of the cabinet 1 to prevent moisture from entering the cabinet 1, thus creating a relatively enclosed space inside the cabinet 1. This is suitable for overseas projects where cable installation permits are unavailable, allowing the mechanical cables to be installed in the factory, avoiding on-site cable installation, reducing secondary cable work on-site, and making the process simpler, more convenient, and more flexible. The control cabinet effectively blocks foreign objects, such as dust and rainwater, from entering the cabinet 1 through the ventilation hood 11 and staggered partitions 12, preventing damage to internal components, without hindering ventilation. The control cabinet has a robust and reliable structure, suitable for mass production.

[0028] Example 2

[0029] like Figures 1-7 As shown in this embodiment, a control cabinet suitable for outdoor circuit breakers is proposed. Compared with Embodiment 1, in this embodiment, the outer door lock includes a lock handle 3 mounted on the outer door 2, a lock plate 31 connected to the lock handle 3, and two sets of linkage limiting components respectively connected to both ends of the lock plate 31. The linkage limiting components include a lock rod 32 rotatably connected to one end of the lock plate 31, a retaining wheel 33 mounted on the other end of the lock rod 32, a bracket 34 mounted on the outer door 2, and an elastic sleeve 35 mounted on the bracket 34. The elastic sleeve 35 is engaged with the bracket 34 and has a channel for the lock rod 32 to pass through. The channel size is larger than the diameter of the lock rod 32, sufficient for the lock rod 32 to move. The lock rod 32 does not move straight up and down, and the lock rod 32 will not jam when unlocking and locking.

[0030] In this embodiment, after the outer door 2 is closed, the lock handle 3 is rotated, which drives the lock plate 31 to rotate. The lock plate 31 is locked onto the cabinet body 1. The lock plate 31 also drives the two lock rods 32 to move. The upper lock rod 32 moves up and the lower lock rod 32 moves down. They are respectively locked onto the top and bottom of the inner side of the cabinet body 1 by two locking wheels 33, thereby achieving three-point limiting and reliable locking.

[0031] The embodiments of the present invention have been described in detail above with reference to the accompanying drawings. However, the present invention is not limited thereto. Various changes can be made within the scope of knowledge possessed by those skilled in the art without departing from the spirit of the present invention.
