[0001] This application relates to the technical field of distribution equipment, and particularly to an outdoor underground prefabricated substation. Background Art
[0002] Prefabricated substations are widely used in the distribution field of urban commercial and civil buildings. Currently, most of the prefabricated substations in use have the transformer and switchgear placed on the same layer, which occupies a large area. Moreover, when the transformer is overloaded, it is prone to catching fire, and the fire is likely to spread around during a fire. Therefore, flammable items cannot be set within a certain range around it. In addition, since half of the transformer coil belongs to the high-voltage part, it will generate a certain amount of electromagnetic interference to the surrounding area. Summary of the Utility Model
[0003] An embodiment of this application provides an outdoor underground prefabricated substation. After the transformer in this outdoor underground prefabricated substation catches fire, it is not easy to spread, the fire is easy to control after ignition, and the transformer has less electromagnetic interference to the surrounding area.
[0004] The outdoor underground prefabricated substation provided by the embodiment of this application includes a prefabricated base cabin, a transformer, a base cabin cover plate, a foundation channel steel, a distribution box body, and a cable clamp cabin. The prefabricated base cabin is buried below the outdoor ground, and the top of the prefabricated base cabin is lower than the ground. The transformer is arranged inside the prefabricated base cabin;
[0005] The base cabin cover plate and the foundation channel steel are arranged above the prefabricated base cabin. The cable clamp cabin is arranged above the foundation channel steel, and the cable clamp cabin has a plurality of openings for the entry and exit of power distribution cables. The distribution box body is arranged above the cable clamp cabin.
[0006] In addition, the outdoor underground prefabricated substation provided by the embodiment of this application may also have the following additional technical features:

[0008] The distribution box body has a front side and a back side in the width direction. One side of the foundation channel steel along the width direction is flush with the front side of the distribution box body and the side line of the prefabricated base cabin. The base cabin cover plate is located directly above the transformer, and the base cabin cover plate extends from the back side of the distribution box body to the other side line of the prefabricated base cabin.
[0009] In an alternative solution, along the length direction of the distribution box body, the prefabricated base cabin is located between the two side edges of the distribution box body. Define the shortest distance from the side edge of the prefabricated base cabin to the corresponding side edge of the distribution box body as L 1 , then L 1 > 50 cm.
[0010] In an alternative solution, as defined, the width of the transformer is L, and the width of the base cabin cover plate is L 2 , then L 2 -L > 10 cm;
[0011] The upper surface of the base cabin cover plate is flush with the ground, and the thickness H of the base cabin cover plate is not less than 10 cm.
[0012] The beneficial effects of the embodiments of the present application are as follows:
[0013] In the outdoor underground prefabricated substation in the embodiments of the present application, the transformer is arranged in the prefabricated base cabin, and then the prefabricated base cabin is buried below the outdoor ground.

[0024] As Figure 1-2 shown, the embodiments of the present application provide an outdoor underground prefabricated substation, which includes a prefabricated base cabin 2, a transformer 1, a base cabin cover 3, a foundation channel steel 4, a distribution box body 5, and a cable clamping cabin 6. Among them, the prefabricated base cabin 2 is buried below the outdoor ground, and the top of the prefabricated base cabin 2 is lower than the ground, and the transformer 1 is arranged in the prefabricated base cabin 2; the base cabin cover 3 and the foundation channel steel 4 are arranged above the prefabricated base cabin 2, the cable clamping cabin 6 is arranged above the foundation channel steel 4, and the cable clamping cabin 6 has a plurality of openings for the access of power distribution cables, and the distribution box body 5 is arranged above the cable clamping cabin 6.
[0025] In this embodiment, the transformer 1 is arranged in the prefabricated base cabin 2, and then the prefabricated base cabin 2 is buried below the outdoor ground. In this way, when the transformer 1 catches fire, it is not easy to spread, and because the ventilation in the underground cabin is not good, the fire is easier to control after it catches fire; the distribution box body 5 and the cable clamping cabin 6 are arranged above the ground, and the base cabin cover 3 and the foundation channel steel 4 are arranged at the position where the prefabricated base cabin 2 is close to the ground, and the transformer 1 has little electromagnetic interference to the surrounding area; the entire outdoor underground prefabricated substation occupies a smaller area, and it is also more convenient to maintain or replace the transformer 1.
[0026] As Figure 2As shown, in a specific embodiment, the distribution box body 5 and the transformer 1 are arranged in a staggered manner, and the projections of the distribution box body 5 and the transformer 1 on the horizontal plane do not overlap. The completely staggered distribution box body 5 and transformer 1 can minimize the impact of the fire on the distribution box body 5 after the transformer 1 catches fire, thereby reducing the losses caused by the fire. The distribution box body 5 has a front surface 51 and a back surface 52 in the width direction. The foundation channel steel 4 is flush with the front surface 51 of the distribution box body 5 and the side line of the prefabricated cabin 2 along one side in the width direction. The cabin cover plate 3 is located directly above the transformer 1, and the cabin cover plate 3 extends from the back surface 52 side of the distribution box body 5 to the other side line of the prefabricated cabin 2. The flush-mounted foundation channel steel 4 and cabin cover plate 3 can reduce the amount of materials used on the premise of playing a preset role, thereby reducing the manufacturing cost of the entire outdoor underground prefabricated substation.
[0027] As Figure 1-2 shown, in a specific embodiment, along the length direction of the distribution box body 5, the prefabricated cabin 2 is located between the two side edges of the distribution box body 5. Define the shortest distance between the side edge of the prefabricated cabin 2 and the corresponding side edge of the distribution box body 5 as L1, then L1 > 50 cm. In addition, if the width of the transformer 1 is defined as L and the width of the cabin cover plate 3 is defined as L2, then L2 - L > 10 cm to facilitate the hoisting of the transformer 1; the upper surface of the cabin cover plate 3 is flush with the ground, and the thickness H of the cabin cover plate 3 is not less than 10 cm.
[0028] The above are only the preferred embodiments of the present application and are not used to limit the present application. For those skilled in the art, various changes and modifications can be made to the present application. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present application shall be included in the protection scope of the present application.
