[0019] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all of the embodiments.

[0020] Refer to Figure 1-3, an outdoor box-type substation, comprising a first box body 1, a box door 101 is hinge-mounted on one side of the first box body 1, a plurality of first ventilation slots 102 are opened on both side walls of the first box body 1, a first plate body 2 is fixed to the bottom end surface of the first box body 1, an opening is provided on the bottom end surface of the first box body 1, the first plate body 2 is fixed at the bottom opening of the first box body 1, and a plurality of second ventilation slots 201 are opened on the first plate body 2. A U-shaped plate 9 is installed on the top end surface of the first plate body 2 by bolts. A first frame body 3 is fixed to the bottom end surface of the first plate body 2. Two cross plates 4 are fixed on the inner side walls of both sides of the first box body 1. Electric push rods 5 are fixed on the top end surfaces of the two cross plates 4. A second plate body 6 is fixed on the telescopic end of the electric push rod 5. A box top 7 is fixed on the second plate body 6. By starting the electric push rod 5, the electric push rod 5 can perform telescopic operations, and the electric push rod 5 drives the second plate body 6 and the box top 7 to move upward, so that the second plate body 6 and the box top 7 can be separated from the top end of the first box body 1, thereby enabling heat dissipation and ventilation operations in the internal space of the first box body 1. The inside of the box top 7 is hollow, and a second frame body 701 is fixed around the bottom end of the box top 7. The orthographic projection area of the second plate body 6 and the box top 7 is larger than the orthographic projection area of the first box body 1. The second frame body 701 on the box top 7 can increase rain protection, preventing rainwater from directly entering the inside of the first box body 1 on rainy days, further avoiding damage to the transformer 10 inside the first box body 1, and effectively improving the service life of the transformer 10. A plurality of third ventilation slots 601 are opened on the second plate body 6. Two heat dissipation mechanisms 8 are installed on the second plate body 6. Both heat dissipation mechanisms 8 include a motor 801. The motor 801 uses a permanent magnet synchronous motor with the model D180M-0160030B-E. The motor 801 is fixed on the second plate body 6. The output shaft of the motor 801 is installed through the outside of the bottom end of the second plate body 6. A fan blade 802 is installed on the output shaft of the motor 801. A U-shaped plate 9 is installed inside the first box body 1. A third plate body 901 is fixed to the bottom end of the U-shaped plate 9. The third plate body 901 is installed on the first plate body 2 by bolts. A plurality of fourth ventilation slots 902 are opened on the third plate body 901. A plurality of fifth ventilation slots 903 are opened on the U-shaped plate 9. A transformer 10 is installed inside the U-shaped plate 9. When starting the motors 801 of the two heat dissipation mechanisms 8, the output shaft of the motor 801 rotates the fan blade 802. When the fan blade 802 rotates, air can enter the inside of the first box body 1. The air enters the inside of the U-shaped plate 9 through a plurality of fifth ventilation slots 903, so that the air can blow towards the transformer 10 inside the U-shaped plate 9, ensuring heat dissipation operations for the transformer 10, further ensuring that the transformer 10 is in a dry environment, and ensuring the use of the transformer 10. The air passing through the transformer 10 then discharges the hot air through a plurality of fourth ventilation slots 902 and a plurality of second ventilation slots 201.

[0021] Usage method and advantages of the present utility model: When this outdoor box-type substation is in use, the working process is as follows:

[0022] As Figure 1 , Figure 2 and Figure 3 shown, when using an outdoor box-type substation, the electrical components in the present utility model are all electrically connected to an external power source and a power switch. The first box body 1, the first plate body 2, and the first frame body 3 are placed at the designated position where the user needs to install. Flip the door 101 hinged on the first box body 1 so that the internal space of the first box body 1 can be opened. The transformer 10 is installed on the first plate body 2 by bolts. At the same time, the transformer 10 is also installed inside the U-shaped plate 9. In good weather, when the transformer 10 generates a large amount of heat after long-term use, start the electric push rod 5 so that the electric push rod 5 can perform telescopic operations. The electric push rod 5 drives the second plate body 6 and the box top 7 to move upward, so that the second plate body 6 and the box top 7 can be separated from the top end of the first box body 1, thereby enabling heat dissipation and ventilation operations in the internal space of the first box body 1. In rainy weather, the second frame body 701 on the box top 7 can increase rain protection to prevent rainwater from directly entering the internal space of the first box body 1 on rainy days, further avoiding damage to the transformer 10 inside the first box body 1 and effectively increasing the service life of the transformer 10. At the same time, start the motors 801 of the two heat dissipation mechanisms 8. The output shafts of the motors 801 rotate the fan blades 802. When the fan blades 802 rotate, air can enter the internal space of the first box body 1. The air enters the inside of the U-shaped plate 9 through a number of fifth ventilation slots 903, so that the air can blow towards the transformer 10 inside the U-shaped plate 9, ensuring heat dissipation operations for the transformer 10 and further ensuring that the transformer 10 is in a dry environment to ensure the use of the transformer 10. The air passing through the transformer 10 then discharges the heated air through a number of fourth ventilation slots 902 and a number of second ventilation slots 201, increasing the heat dissipation method and ensuring the heat dissipation effect.
