[0002] Substation is the place where the voltage and current of electric energy are transformed, concentrated and distributed in the power system. In order to ensure the quality of electric energy and the safety of equipment, voltage adjustment, flow control, and protection of transmission and distribution lines and major electrical equipment are also required in the substation.

[0003] For example, the prefabricated substation with the authorization announcement number "CN214673852U" has solved the problem of water entering the internal electronic instruments of the existing prefabricated substation, causing serious consequences. The water source on the base is discharged through the diversion hole, so it can prevent the water source from entering the box body and causing safety accidents. At the same time, the base raises the bottom of the box body, which can further prevent the ground water source from flowing into the box body. Considering that most of the substations need to find the pre-installation position after installing, the embedded connector is passed through the box body and the nut for connection, which makes the pre-installation process more troublesome.

[0008] Preferably, an air inlet is installed on the outer wall of the box cover, and a filter is installed on the inner wall of the air inlet.

[0009] Preferably, the lower end of the box body is fixedly connected to the sealing gasket, and the lower end of the sealing gasket is in contact with the pre-installed seat.

[0010] Preferably, the surface of the pre-installed seat is provided with a first threaded hole, an assembly hole and an exhaust port, and the outer wall of the box cover is provided with a second threaded hole.

[0011] The utility model proposes a prefabricated substation, which has the beneficial effect of separating the pre-installed seat and the box body, and only needs to fix the pre-installed seat and the installation position before pre-installation.

[0026] Working principle:

[0027] Pre-installation stage

[0028] First, use external rivets or the like to pass through the first threaded hole 9 to fix the pre-installed seat 306 at the required position, so that the reserved installation stage is completed. When the substation needs to be installed, place the box 1 on the upper end of the pre-installed seat 306, and ensure that the block 305 at the lower end of the box 1 enters the assembly hole 10 on the surface of the pre-installed seat 306.

[0029] Installation Phase

[0030] Open the door panel 2 on the box body 1, and manually rotate the round rod 304 to drive the block 305 to move to the other side of the assembly hole 10, so that the block 305 is blocked by the pre-installed seat 306 and cannot be separated from the assembly hole 10. At the same time, the round block 303 on the round rod 304 rotates inside the mounting block 302 to ensure that the round rod 304 and the box body 1 are in a connected relationship. Continue to put the box cover 403 vertically on the upper end of the box body 1, turn the fixing screw 402 to rotate it into the connecting column 401 for threaded connection, and the outer side of the fixing screw 402 will press against the box The outer wall of the cover 403 is installed between the box cover 403 and the box body 1. When working, the air entering through the air inlet 7 from the outside is filtered by the filter 13, and then continues to enter the interior of the box body 1 from the flow cavity 404. At the same time, the air at the lower end of the box body 1 is filtered by the filter bottle 6 from the connecting pipe 5, and finally discharged to the outside through the exhaust port 11, so as to achieve the effect of internal air flow. According to actual needs, the second threaded hole 12 can also be used to install a cooling fan on the outer wall of the air inlet 7 to achieve the effect of accelerating the internal air flow.
