Description

Technical Field

[0001] This utility model relates to the field of prefabricated substation technology, and in particular to an outdoor steel structure prefabricated substation. Background Technology

[0002] Outdoor steel structure prefabricated substations are integrated and modular outdoor power equipment. They enclose transformers, high and low voltage switchgear, protection devices, and other electrical equipment within a steel structure enclosure. This equipment is fully enclosed, dustproof, moisture-proof, and corrosion-resistant, allowing direct installation in outdoor environments without the need for a separate distribution room. Its steel structure enclosure provides IP54 or higher protection rating and is equipped with an intelligent temperature control system, capable of adapting to harsh environmental temperature variations from -40℃ to +50℃, enabling it to receive, transform, and distribute electrical energy. These substations are characterized by their compact structure, quick installation, convenient maintenance, and small footprint, and are widely used in urban power distribution networks, industrial parks, and new energy power plants, serving as crucial distribution node equipment in modern power systems. However, existing outdoor steel structure prefabricated substations still suffer from poor cooling capabilities and inability to isolate themselves from the damp environment of the ground.

[0003] Therefore, it is essential to invent an outdoor steel-structured box-type substation. Utility Model Content

[0004] To address the aforementioned technical problems, this utility model provides an outdoor steel structure prefabricated substation, solving the issues of poor cooling capacity and inability to isolate the substation from the damp environment of the ground. An outdoor steel structure prefabricated substation includes a transformer box, a stabilizing base, a sealed door, a circulating cooling mechanism, a sealed roof, a sunshade roof, and a rainproof curtain. The stabilizing base is fixedly installed on the ground, and the transformer box is fixedly installed on the surface of the stabilizing base. The sealed door is installed on one side of the transformer box. The circulating cooling mechanism is fixedly installed on the outer walls at both ends of the transformer box, and the sealed roof is fixedly installed on the top of the transformer box. The sunshade roof is fixedly installed above the sealed roof. The rainproof curtain is fixedly installed at one end of the sunshade roof.

[0005] The stabilizing base includes a base plate, a lifting mounting platform, a mounting bracket, and a vegetation area. The base plate is fixedly installed on the ground, and the lifting mounting platform is fixedly installed on the surface of the base plate. The mounting bracket is fixedly installed on the surface of the lifting mounting platform, and the vegetation area is located at one end of the surface of the base plate. A transformer box is fixedly installed on top of the mounting bracket.

[0006] The circulating cooling mechanism includes a mounting plate, an air chamber, an air outlet, a connecting plate, and a fan. The mounting plate is fixedly installed on the outer walls at both ends of the transformer box, and the air chamber is fixedly installed on the surface of the mounting plate. The air outlet is fixedly installed on the air chamber, and the fan is fixedly installed on the air outlet through the connecting plate.

[0007] The base plate and lifting platform inside the stable base are made of concrete, and the lifting platform and mounting bracket lift the transformer box off the ground; the vegetation area is a soil layer, and the surface of the vegetation area is covered with plants, which can carry out respiration and transpiration.

[0008] The circulating cooling mechanism consists of a pair of identical structures. One set of air vents faces upwards as the air outlet, exhausting air outwards, while the other set faces downwards as the air inlet, drawing air inwards. The air inlet of the circulating cooling mechanism faces the vegetation area and draws in low-temperature air from below via a fan. The air outlet of the circulating cooling mechanism faces upwards and exhausts high-temperature air floating upwards via a fan, which is then shielded by a rain curtain.

[0009] Compared with the prior art, the present invention has the following beneficial effects:

[0010] 1. The stable base of this utility model provides a solid foundation support through the base plate, and the lifting platform lifts the substation body off the ground to isolate moisture and high surface temperature. It can utilize the transpiration and carbon sink function of plants in the vegetation area, and cooperate with the fan of the circulating cooling mechanism to draw cooling air to form an ecological and mechanical synergistic cooling system. This structure integrates three major functions: load distribution, microclimate regulation, and energy consumption optimization, which is a key guarantee for the efficient operation of substations.

[0011] 2. The circulating cooling mechanism of this utility model adopts a dual-circulation design with low-level air intake and high-level air exhaust. A fan actively draws in low-temperature air from the vegetated area and inputs it into the housing, while simultaneously exhausting hot air from inside, forming a forced convection circulation. This mechanism, together with the vegetation cooling of the stable base and the heat insulation function of the sun-shielding roof, constitutes a three-stage temperature control system. This system can keep the internal temperature of the substation 10-15℃ lower than the ambient temperature, and the ventilation efficiency is 2-3 times that of natural convection, ensuring stable operation of the equipment in high-temperature environments.

[0018] To enable those skilled in the art to better understand the present invention, the technical solutions in the embodiments of the present invention will be clearly and completely described below. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort should fall within the protection scope of the present invention.

[0019] As attached Figure 1 To be continued Figure 4 As shown.

[0020] This utility model provides an outdoor steel structure box-type substation, including a transformer box body 1, a stabilizing base 2, a sealing door 3, a circulating cooling mechanism 4, a sealed roof 5, a sunshade roof 6, and a rainproof curtain 7. The stabilizing base 2 is fixedly installed on the ground, and the transformer box body 1 is fixedly installed on the surface of the stabilizing base 2. The sealing door 3 is installed on one side of the transformer box body 1. The circulating cooling mechanism 4 is fixedly installed on the outer walls at both ends of the transformer box body 1, and the sealed roof 5 is fixedly installed on the top of the transformer box body 1. The sunshade roof 6 is fixedly installed above the sealed roof 5. The rainproof curtain 7 is fixedly installed at one end of the sunshade roof 6.

[0021] The stabilizing base 2 includes a base plate 21, a lifting mounting platform 22, a mounting bracket 23, and a vegetation area 24. The base plate 21 is fixedly installed on the ground, and the lifting mounting platform 22 is fixedly installed on the surface of the base plate 21. The mounting bracket 23 is fixedly installed on the surface of the lifting mounting platform 22, and the vegetation area 24 is located at one end of the surface of the base plate 21. A transformer box 1 is fixedly installed above the mounting bracket 23.

[0022] The circulating cooling mechanism 4 includes a mounting plate 41, an air chamber 42, an air outlet 43, a connecting plate 44, and a fan 45. The mounting plate 41 is fixedly installed on the outer walls at both ends of the transformer box 1, and the air chamber 42 is fixedly installed on the surface of the mounting plate 41. The air outlet 43 is fixedly installed on the air chamber 42, and the fan 45 is fixedly installed on the air outlet 43 through the connecting plate 44.

[0023] The base plate 21 and the lifting mounting platform 22 inside the stable base 2 are made of concrete, and the lifting mounting platform 22 and the mounting bracket 23 lift the transformer box 1 off the ground; the vegetation area 24 is a soil layer, and the surface of the vegetation area 24 is covered with plants, which can carry out respiration and transpiration.

[0024] The circulating cooling mechanism 4 consists of a pair of identical structures. One set of air vents 43 of the circulating cooling mechanism 4 faces upward as the air outlet, exhausting air outward, while the other set of air vents 43 of the circulating cooling mechanism 4 faces downward as the air inlet, drawing air inward. The air inlet vents 43 of the circulating cooling mechanism 4 face the vegetation area 24 and draw in low-temperature air from below through the fan 45. The air outlet vents 43 of the circulating cooling mechanism 4 face upward and exhaust air outward through the fan 45, expelling the high-temperature air that floats upward, and are shielded by the rain curtain 7.

[0025] This equipment employs a triple temperature control system of passive protection, active heat dissipation, and intelligent regulation to achieve a highly efficient and stable operating environment. The high-reflective coating of the sun-shielding roof 6 and the air insulation layer of the sealed roof 5 block over 90% of solar radiation heat. Simultaneously, the vegetation zone 24 of the stable base 2 utilizes plant transpiration to cool the surrounding air by 3-5°C. The circulating cooling mechanism 4 uses two sets of fans 45 to create forced convection, delivering the pre-cooled air from the vegetation into the transformer box 1 and expelling hot air from the top, achieving an air exchange rate of 20 m³ per hour and ensuring that the internal temperature of the equipment remains 10-15°C lower than the ambient temperature.

[0026] This equipment combines ecological cooling with mechanical heat dissipation, automatically adjusting operating parameters through an integrated intelligent control system. Temperature and humidity sensors installed inside the transformer substation 1 monitor the internal environment in real time. When the temperature exceeds 35℃, the circulating cooling mechanism 4 automatically activates, switching to full-speed mode at 50℃. When the humidity exceeds 80%, the bottom air intake is shut off, switching to top-mounted unidirectional exhaust. This intelligent temperature control system, combined with photovoltaic auxiliary power supply, can reduce operating energy consumption by 40%, resulting in an annual carbon emission reduction of over 50kg. It fully complies with international electrical standards for outdoor substation temperature control, demonstrating significant energy-saving and environmental advantages.

[0027] Any technical solution that achieves the above-mentioned technical effects by utilizing the technical solution described in this utility model, or by designing a similar technical solution inspired by the technical solution described in this utility model, falls within the protection scope of this utility model.
