Abstract
Description
Technical Field
[0001] This utility model relates to the field of power equipment technology, specifically to a prefabricated substation heat dissipation duct structure. Background Technology
[0002] Prefabricated substations, also known as box-type substations, are compact, complete sets of power distribution facilities that house power transformers, high and low voltage switchgear, control equipment, and auxiliary equipment within a single enclosure structure. Most of the wiring and cabling between the internal equipment is prefabricated in the factory.
[0003] Prefabricated box-type substations are mobile substation devices that integrate high-voltage switchgear, transformers, and low-voltage switchgear, and are assembled in the manufacturing plant. These devices have a wide range of applications due to their small size, ease of on-site construction, lack of building requirements, simple operation, and high reliability. However, existing prefabricated substations are enclosed structures, and the switching of internal transformer components can easily lead to excessive internal temperature rise. Therefore, heat dissipation is necessary for prefabricated substations.
[0004] Conventional prefabricated substations (European-style box-type transformers) have two heat dissipation methods: one is natural ventilation through louvers, and the other is forced cooling by fans. However, when box-type transformers are used in shopping malls, important facilities, etc., direct exhaust to the outside will affect the normal use and safety of surrounding precision instruments and equipment. Summary of the Invention
[0005] This invention addresses the shortcomings of existing technologies by providing a prefabricated substation cooling duct structure. This structure is characterized by its simple structure, small footprint, good operational stability, and excellent heat dissipation. It solves the problem of direct exhaust air from the substation interfering with surrounding precision instruments and equipment, and prevents the surrounding environment from heating up due to the exhaust heat.

A top side plate fan is installed between the air outlet and the cooling duct. Each side plate includes a fixed side plate and a door side plate, and both the fixed side plate and the door side plate have several ventilation windows.
[0008] Preferably, a transformer is provided on the upper end of the base frame, a high-voltage cabinet connected to the transformer phase circuit is provided on one side of the transformer, a low-voltage auxiliary cabinet is provided on the other side of the transformer, and several low-voltage incoming line cabinets connected to the low-voltage auxiliary cabinet and the transformer phase circuit are provided between the low-voltage auxiliary cabinet and the transformer.

[0010] An SVG (Static Var Generator) is a reactive power compensation device based on power electronics technology, primarily used to regulate the reactive power and voltage stability of the power grid. It rapidly responds to the reactive power demand of the grid by controlling the phase and amplitude of the current, thereby improving power quality and enhancing the stability and reliability of the power grid.
[0011] Preferably, the top cover is provided with several top cover fans that penetrate the top cover, and the top side plate fans and air outlets, as well as the top cover fans and the top cover, are all installed and fixed by an embedded structure.

[0020] The technical solution of this utility model will be further described in detail below through embodiments and in conjunction with the accompanying drawings.
[0021] Example: Figure 1 , Figure 2 and Figure 3 As shown, a prefabricated substation cooling duct structure includes a base frame 8, with lifting holes 9 connected to each other on both sides of the base frame 8 at the front and rear ends. A transformer 15 is mounted on the upper end of the base frame 8. A high-voltage cabinet 17 connected to the phase circuit of the transformer 15 is located on one side of the transformer 15, and a low-voltage auxiliary cabinet 13 is located on the other side of the transformer 15. Two low-voltage incoming line cabinets 14 connected to the phase circuits of the low-voltage auxiliary cabinet 13 and the transformer 15 are located between the low-voltage auxiliary cabinet 13 and the transformer 15. Two SVG cabinets 18 connected to the phase circuits of the transformer 15 are located at the front end of the low-voltage incoming line cabinets 14. Bottom ventilation grilles 16, which are through-type supports for the bottom frame 8, are located at the lower ends of the SVG cabinets 18 and the transformer 15. Side plates 5 are located on the four sides of the upper end of the base frame 8. Each side plate 5 includes a fixed side plate 11 and a door side plate 12. Several ventilation windows 10 are provided on both the fixed side plate 11 and the door side plate 12. A top cover 2 is provided at the upper end of the side panel 5. A top side panel 4 is provided between the top cover 2 and the side panel 5. An air outlet 3 is provided on the top side panel 4. A heat dissipation pipe 1 connected to the air outlet 3 is provided around the top cover 2. A top side panel fan 6 is provided between the air outlet 3 and the heat dissipation pipe 1. Four top cover fans 19 are provided at the upper end of the top cover 2, penetrating the top cover 2. The top side panel fans 6 and the air outlet 3, as well as the top cover fans 19 and the top cover 2, are all installed and fixed with an embedded structure. A flange connection pipe 7 connected to the top side panel fan 6 is provided between the heat dissipation pipe 1 and the air outlet 3.
[0022] The heat dissipation pipe 1 is embedded in the top side plate 4. The air outlet 3 of the top side plate 4 is connected to the heat dissipation pipe 1. The hot air in the substation is blown to the heat dissipation pipe 1 by the top side plate fan 6 and the top cover fan 19. The heat dissipation pipe 1 transfers the heat to the outside. The bottom ventilation grille plate 16 and ventilation window 10 are used for air intake. The air flow carries away a large amount of heat from the transformer room.
