Install the corresponding size hinge plate on the outlet 7 of the switchgear 6. When laying cables, use cable clamps 3 to hold the cable clamps 3 on the cable bracket 1. To facilitate the cable passing through the hinge plate from the switchgear 6, the hinge plate can be opened during cable laying, and closed and tightened with bolts after laying. After wiring is completed, if there is a deviation between the position of the cable clamp 3 and the actual cable route, the cable clamp 3 can be opened and its position adjusted. The vertical position of the cable clamp 3 can also be adjusted by adjusting the height of the flat steel to prevent assembly stress and better protect the cable.

[0074] The vehicle-mounted mobile substation switchgear incoming and outgoing line system 5 of this utility model is a switchgear 6 incoming and outgoing line system that integrates cable bracket 1, hinge plate, and cable clamp 3.

[0075] The cable bracket 1, cable clamp 3, and hinge plate are used together to clamp, fix, and protect the cables entering and exiting the switchgear 6.

The cable clamp 3 is installed on the cable bracket 1 and serves to clamp and protect the cables.

[0078] The position of cable clamp 3 can be adjusted in both the horizontal and vertical directions, and can be precisely adapted to the actual cable route to better protect the cable.

[0080] Specifically, in this embodiment, for the vehicle-mounted mobile substation, the cable bracket 1 is installed on the semi-trailer beam 4, and the hinge plate is installed on the bottom or side of the switchgear 6. The bottom of the switchgear 6 corresponds to the vehicle's load-bearing surface, allowing the cables inside the switchgear 6 to pass through the hinge plate. The hinge plate provides a certain clamping and fixing effect on the cables and can be closed and the tower-type protective coil installed during the transportation of the vehicle-mounted mobile substation, thereby improving the sealing of the switchgear 6's internal compartment. When the cables passing through the hinge plate pass through the cable bracket 1, they can be directly tied to the cable bracket 1 or fixed using several cable clamps 3. Then, the cables are connected to the power distribution equipment, forming a switchgear 6 incoming and outgoing line system, achieving reliable clamping and fixing of the cables outside the switchgear 6.

[0081] The vehicle-mounted mobile substation switchgear incoming and outgoing line system 5 in this embodiment is applicable not only to vehicle-mounted mobile substation switchgear 6, but also to other mobile substation switchgear 6.

[0082] The vehicle-mounted mobile substation switchgear incoming and outgoing line system 5 and the vehicle-mounted mobile substation in this embodiment can reliably install cables outside the switchgear 6 when it is difficult to fix cables inside the switchgear 6. The cables are clamped and fixed outside the switchgear 6, improving the stability and reliability of the cable arrangement. This system can be installed on the semi-trailer beam 4 or other support beams of the mobile substation, and the incoming and outgoing cables are fixed by hinges and cable clamps 3. This structure allows for cable fixing outside the switchgear 6, reducing the space occupied inside the switchgear 6, thereby reducing the height of the switchgear 6 and improving its applicability in height-restricted situations. It is suitable for sealing openings in both operating and non-operating (such as transport) states of the mobile substation. Furthermore, the hinges of this structure can be opened and closed via hinges, facilitating installation and improving the protective performance of the switchgear 6's internal compartment. The cable bracket 1 has a simple, robust, and reliable structure, ensuring cable support outside the switchgear 6.
