Description

Technical Field

[0001] This utility model relates to the field of substation technology, and in particular to a prefabricated outdoor box-type substation. Background Technology

[0002] Prefabricated box-type substations refer to devices in which the main equipment of the substation, such as transformers, high-voltage switchgear, and low-voltage switchgear, are pre-assembled and debugged in the factory and installed in a specially designed enclosed box. There is no need for complicated equipment installation and debugging work on the construction site. The prefabricated box-type substation can be put into use simply by transporting it to the designated location, carrying out simple foundation construction and connecting external lines. This greatly saves on-site construction time and can quickly meet the power needs of users.

[0003] Prefabricated outdoor box-type substations generate heat from their internal components during use, thus requiring a heat dissipation system. Existing air-cooled systems often require gas to be delivered into the box to carry away the heat from the surface of the components. To prevent the gas entering the box from carrying dust and affecting the heat dissipation of the components, filters such as screens are installed.

[0004] After a period of use, the filter screen inside a prefabricated outdoor box-type substation will accumulate dust on its surface. Some of the dust will clog the filter pores, reducing the airflow into the box and affecting the heat dissipation of the internal components. Existing prefabricated outdoor box-type substations can only be cleaned manually every once in a while, which is not only inconvenient but also requires stopping the cooling system during cleaning, thus affecting the normal operation of the substation. Based on the above problems, a prefabricated outdoor box-type substation is proposed. Utility Model Content

[0021] Reference Figure 1-4A prefabricated outdoor box-type substation includes a box body 1. A mounting frame 4 is fixedly installed on the top of the box body 1. A filter cartridge 8 is rotatably installed inside the mounting frame 4 via bearings. Filter holes 11 are opened on the surface of the filter cartridge 8. A first rotating shaft 7 is fixedly installed inside the filter cartridge 8. A connecting plate 21 is rotatably installed on the right side of the filter cartridge 8. An air inlet 14 is opened on the surface of the connecting plate 21. A second rotating shaft 9 is rotatably installed inside the connecting plate 21. A cleaning brush 10 is fixedly installed on the surface of the second rotating shaft 9. A fixing plate 19 is fixedly installed on the top of the box body 1. The fixing plate 19 and the first rotating shaft 7 are rotatably connected. A drive assembly is installed on the surface of the first rotating shaft 7. The drive assembly includes a motor 6 fixedly installed on the left end of the first rotating shaft 7. The output end of the motor 6 is fixedly connected to the first rotating shaft 7. A bracket 5 is fixedly installed on the surface of the motor 6. The bracket 5 and the mounting frame 4 are fixedly connected. The prefabricated outdoor box-type substation is equipped with a drive gear 12, and a driven gear 13 meshes with the surface of the drive gear 12. The driven gear 13 is fixedly connected to the second rotating shaft 9. A cooling unit is installed on the top of the box 1, and a component group 22 is fixedly installed inside the box 1. When the start motor 6 is activated, it drives the first rotating shaft 7 to rotate. The rotation of the first rotating shaft 7 drives the filter cartridge 8 to rotate. At the same time, the rotation of the first rotating shaft 7 drives the drive gear 12 to rotate. The rotation of the drive gear 12 drives the driven gear 13, which meshes with it, to rotate. The rotation of the driven gear 13 drives the second rotating shaft 9 to rotate. The rotation of the second rotating shaft 9 drives the cleaning brush 10 to rotate. The cleaning brush 10 cleans the filter cartridge 8 during the rotation process. This device can clean the filter device inside the heat dissipation system, preventing dust from clogging the filter holes 11 and affecting the heat dissipation effect on the internal components of the substation. At the same time, the heat dissipation system does not need to be stopped during cleaning.

[0022] Specifically, the cooling system includes a processing box 15 fixedly mounted on the top of the housing 1. An air intake pump 17 is fixedly mounted on the left side of the processing box 15, with its outlet end penetrating through the processing box 15 and extending into its interior. Multiple thermoelectric coolers 16 are fixedly mounted inside the processing box 15, arranged linearly. The cold ends of the thermoelectric coolers 16 are located inside the processing box 15, while their hot ends are located outside. An air supply pipe 18 is fixedly mounted on the right side of the processing box 15, with its inlet end penetrating through the processing box 15 and extending into its interior. The outlet end of the air supply pipe 18 penetrates through a fixing plate 19 and a connecting plate 21. Extending to the left side of the connecting plate 21, the air intake pump 17 is started to draw gas into the processing box 15 and cool it through the cold end of the semiconductor cooling chip 16. Then, the low-temperature gas enters the left side of the fixed plate 19 through the gas supply pipe 18, and then enters the filter cartridge 8 through the air inlet 14. It then enters the box 1 through the filter holes 11 on the surface of the filter cartridge 8, so that the gas entering the box 1 for heat dissipation is cooled down. The cold air can improve the heat dissipation effect on the substation components. An exhaust pump 20 is fixedly installed on the right side of the box 1. The air inlet of the exhaust pump 20 penetrates the box 1 and extends into the interior of the box 1. Starting the exhaust pump 20 can extract the gas after it has been cooled down, so as to prevent the high-temperature gas from staying inside the substation and affecting heat dissipation.

[0023] Specifically, the surface of the housing 1 is hinged with a door 2, and the bottom of the housing 1 is fixed with a set of casters 3 by bolts. There are multiple casters 3, and the multiple casters 3 are distributed in a rectangular array. Opening the door 2 allows for the inspection of the internal component group 22. The casters 3 facilitate the movement of the device. The casters 3 are self-locking casters, which can prevent the device from moving further after it has been transported to the designated position.

[0024] All electrical components mentioned in this article are connected to an external main controller and 220V AC mains power, and the main controller can be a conventional known device such as a computer that can control it.

[0025] In use: Start the air intake pump 17 to draw gas into the processing chamber 15 and cool it through the cold end of the semiconductor cooling chip 16. Then, the low-temperature gas enters the left side of the fixed plate 19 through the gas supply pipe 18, and then enters the filter cartridge 8 through the air intake hole 14. It enters the chamber 1 through the filter holes 11 on the surface of the filter cartridge 8 to dissipate heat from the component group 22. Then, start the exhaust pump 20 to extract the cooled gas. At the same time, the motor 6 drives the first rotating shaft 7 to rotate. The rotation of the first rotating shaft 7 drives the filter cartridge 8 to rotate. The rotation of the first rotating shaft 7 drives the second rotating shaft 9 to rotate through the drive gear 12 and the driven gear 13. The rotation of the second rotating shaft 9 drives the cleaning brush 10 to clean the filter cartridge 8 during the rotation process.

[0026] In summary, this prefabricated outdoor box-type substation, starting motor 6 drives the first rotating shaft 7 to rotate, the first rotating shaft 7 drives the filter cartridge 8 to rotate, and at the same time the first rotating shaft 7 drives the drive gear 12 to rotate, the drive gear 12 drives the driven gear 13 that meshes with it to rotate, the driven gear 13 drives the second rotating shaft 9 to rotate, the second rotating shaft 9 drives the cleaning brush 10 to rotate, and the cleaning brush 10 cleans the filter cartridge 8 during the rotation process.
