[0019] It is easy to understand that according to the technical solution of the utility model, without changing the essential spirit of the utility model, a person skilled in the art can propose a variety of interchangeable structural modes and implementation modes. Therefore, the following specific implementation modes and drawings are only exemplary descriptions of the technical solution of the utility model, and should not be regarded as the entirety of the utility model or as a limitation or restriction to the technical solution of the utility model.

[0020] According to one embodiment of the present invention, Figure 1-Figure 3 Shown.

[0021] like Figure 1 as well as Figure 3 As shown, for the overall structure, in this embodiment, a closed switch cabinet includes: a cabinet body 1 with a square structure, the front side of the cabinet body 1 is hollowed out and a semi-open door lock plate 2 is hinged on the front side, the door lock plate 2 is provided with an electromagnetic lock 3 of an electrical switch at the opening and closing position corresponding to the cabinet body 1, an integrated lining cabinet 4 is fixed in the cabinet body 1, and PV cable ducts 5 are correspondingly arranged on multiple inner wall surfaces in the lining cabinet 4, each of the PV cable ducts 5 is respectively fixed on the inner wall of the lining cabinet 4 through a corresponding fixing part, the PV cable duct 5 is a U-shaped structure with a hollow center, and a cable groove 6 is recessed around one side of the outer edge, with the front side of the cabinet body 1, the PV cable duct 5 fixing directions include parallel upright placement, vertical flat placement and vertical standing placement, and the PV cable ducts 5 on the inner wall surface of each lining cabinet 4 are arranged in groups with equal spacing.

[0022] By positioning and installing the wire duct 6 in multiple installation directions on multiple inner walls of the lining cabinet 4, the cable wiring requirements of the subsequent electrical component installation process can be met to ensure that the internal line layout of the switch cabinet is safer and more reasonable, which is convenient for later maintenance. The overall structure is isolated and closed by the design of the lining cabinet 4 and the outer cabinet body 1, and the electromagnetic lock 3 of the electrical switch is used to seal the overall structure. The sealing structure is more reliable and moisture-proof and pollution-proof.

[0023] Furthermore, the convex depth of one side of the outer edge of the PV wire trough 5 is not less than 2mm, and the corners and the concave parts at the corners are chamfered. The two ends of the convex part of one side of the outer edge of the PV wire trough 5 are chamfered. Sufficient groove depth can ensure that the signal cable is fully accommodated, and the two chamfers corresponding to the concave parts can avoid the cable damage caused by the large corner when winding, and at the same time, the two ends of the corresponding concave parts can relatively compress the wrapped cables, which is beautiful and reliable.

[0024] Furthermore, the fixing part includes a ladder 7 and a U-shaped plug-in platform 8. The back side of the parallel square PV cable trough 5 and the back side of the vertically standing PV cable trough 5 corresponding to the fixing direction are both fixed to the inner wall of the lining cabinet 4 through the ladder 7. The PV cable trough 5 corresponding to the fixing direction being vertically laid flat passes through the U-shaped plug-in platform 8 and is fixed to the inner wall of the lining cabinet 4.

[0025] Furthermore, the U-shaped plug-in platform 8 is inserted and fixed at one end of the short side of the PV wire trough 5, and the distance between its top and the inner wall of the liner cabinet 4 is not less than 3 cm. Sufficient spacing distance can ensure the convenience of threading in the subsequent wiring process, and arranging it at one end of the short side of the PV wire trough 5 can further reduce the threading length.

[0026] Furthermore, an air cooling module 9 is fixed to the top of the inner lining cabinet 4 to reduce heat and temperature when the internal electrical components are working.

[0027] Furthermore, the cabinet 1 is also connected to a terminal box 10 on the outside, a power interface 11 is integrated at the bottom of the terminal box 10, and a plurality of wiring ports 12 are integrated on the side of the cabinet 1 away from the terminal box 10. Lifting rings 13 are symmetrically fixed at both ends of the top of the cabinet 1, and foot pads 14 are fixed at the four corners of the outer bottom. The lifting rings 13 are used to facilitate the lifting and transportation of the switch cabinet as a whole, and the foot pads 14 are used to stably place the switch cabinet as a whole.

[0028] The technical scope of the present invention is not limited to the contents described above. Those skilled in the art can make various deformations and modifications to the above embodiments without departing from the technical concept of the present invention, and these deformations and modifications should all fall within the protection scope of the present invention.
