Description

Technical Field

[0001] This application relates to the field of stainless steel transformer substation technology, and in particular to a stainless steel transformer substation with anti-salt spray function. Background Technology

[0002] A prefabricated substation, also known as a prefabricated transformer substation, is a factory-prefabricated, compact indoor or outdoor power distribution device that integrates high-voltage switchgear, distribution transformers, and low-voltage power distribution equipment according to a specific wiring scheme. It organically combines the functions of transformer voltage reduction and low-voltage power distribution.

[0003] However, research has revealed the following technical problems: When the transformer substation is installed outdoors, especially in coastal areas, industrial areas, and high-dust areas, salt spray particles and dust in the air will enter the equipment with the airflow. If they directly contact the internal electrical components, they will gradually corrode the metal parts and damage the insulation layer, eventually leading to faults such as short circuits and leakage. After long-term use, the filter screen of traditional transformer substations will be blocked by salt crystals and dust, resulting in a decrease in filtration efficiency. Unfiltered salt spray directly contacts the electrical components, accelerating metal corrosion and insulation layer aging, eventually causing faults such as short circuits and insulation failure. After drainage, traditional transformer substations often have water or droplets remaining at the bottom. Especially in rainy and high-humidity environments, the water is difficult to evaporate naturally, causing the inside of the transformer substation to be in a damp state for a long time. This water will seep through the connection gaps of the transformer body, causing corrosion and affecting the structural stability of the transformer substation.

[0004] In response to the aforementioned technologies, a solution is proposed. Summary of the Invention

A load-bearing base plate is provided at the bottom of the box-type transformer body.

[0008] The anti-collision base is located below the load-bearing base plate. A hollow reinforcing bracket is welded to the center of the inner cavity of the anti-collision base.

[0011] Preferably, an insect screen is installed on the side of the air intake connecting cylinder away from the mounting box, and a filter screen is installed on the opposite side between the insect screen and the self-driving fan blade. The filter screen is composed of an activated carbon layer and a fiber layer integrated in a layered composite manner.

[0013] Preferably, corrosion-resistant fans are installed on both sides of the upper end of the mounting box, the output end of the corrosion-resistant fans is connected to a connecting pipe, and the input end of the corrosion-resistant fans is connected to the mounting box.

[0014] Preferably, an air supply pipe is installed at the upper end of the anti-collision base, and the ends of the two sets of connecting pipes away from the anti-corrosion fan are connected to the pipe body of the air supply pipe.

[0015] Preferably, a drain outlet is provided at the front of the upper end of the load-bearing base plate, and an air inlet is provided at the rear of the upper end of the load-bearing base plate.

[0018] In summary, this application includes at least one of the following beneficial technical effects:

[0019] 1. The linkage design of the ratchet structure and the self-driven fan blades realizes the self-cleaning and anti-clogging function of the filter screen. It can shake off residual impurities such as salt crystals and dust attached to the surface of the filter screen through high-frequency micro-vibration, avoiding the filter screen from reducing filtration efficiency due to long-term accumulation and clogging. It is suitable for long-term stable operation in harsh environments such as coastal areas and high dust. At the same time, it can maintain the filter screen permeability in real time, ensuring that the air entering the installation box is always fully filtered, so that the salt spray concentration of the airflow sent into the transformer body remains at a low level, effectively protecting the electrical components in the high-voltage compartment, low-voltage compartment and transformer compartment from corrosion and reducing the risk of insulation failure.

[0020] 2. The air blowing assembly achieves air drying inside the impact-resistant base through the linkage of the bevel gear shaft. It can accelerate the evaporation of water accumulated at the bottom of the impact-resistant base after drainage, blow away residual droplets, and quickly remove water in conjunction with the bottom slope and electric drain valve. This can effectively reduce the humidity inside the base, avoid the corrosion of the internal structure by the long-term damp environment, keep the inside of the base dry, prevent moisture from penetrating into the transformer body, avoid damage to the load-bearing base plate and the connecting parts below due to moisture, reduce equipment safety hazards caused by the aging of the base structure, and ensure that the transformer maintains stable support performance during long-term use.

[0032] The following is in conjunction with the appendix Figure 1 -Appendix Figure 10 This application will be described in further detail below.

[0033] This application discloses a stainless steel box-type transformer with anti-salt spray function.

[0034] The system includes a transformer substation body 1, an anti-collision base 8, an air blowing assembly 13, and an anti-salt spray assembly 14. A transformer compartment 2 is located at the center of the inner cavity of the transformer substation body 1. As the core frame of the entire system, the transformer substation body 1 provides the installation foundation and protective shell for all internal functional areas and components. The stainless steel material effectively resists corrosion from the external environment, ensuring the safe operation of the internal equipment. Its structural design ensures a rational layout of each area, facilitating equipment integration and maintenance. The transformer compartment 2 is specifically designed to house the transformer, providing it with an independent and enclosed operating space, reducing interference from external environmental factors, promoting heat dissipation, ensuring stable operation, and facilitating individual inspection and maintenance of the transformer. A high-voltage compartment 3 is located on the left side of the transformer compartment 2, used for installing high-voltage... Related electrical equipment enables centralized placement and isolation of high-voltage equipment, reducing the safety impact of high-voltage equipment on other areas, improving operational safety, and facilitating the management and maintenance of high-voltage equipment. A low-voltage room 4 is located on the right side of the transformer room 2, where low-voltage electrical equipment is centrally installed, forming a partition with the high-voltage room 3 to avoid mutual interference between high and low voltage equipment, facilitating the control, allocation, and maintenance of low-voltage circuits, and ensuring the stable operation of the low-voltage power distribution system. The bottom of the transformer body 1 is equipped with a load-bearing base plate 7, which bears the weight of the transformer body 1 and all internal equipment, providing a stable bottom support for the transformer. Reinforcing ribs are provided inside to enhance the stability and load-bearing capacity of the overall structure, while separating the transformer body 1 from the impact-resistant base 8, reducing the impact of the bottom environment on the interior of the transformer.

[0035] The anti-collision base 8 is located below the load-bearing base plate 7, providing a solid bottom support for the entire transformer substation. Its structural design effectively resists external collision impacts, protecting the transformer substation body 1 and internal equipment from damage and enhancing the equipment's impact resistance in complex outdoor environments. A hollow reinforcing bracket 11 is welded to the center of the inner cavity of the anti-collision base 8, enhancing the structural strength and stability of the anti-collision base 8, improving its load-bearing capacity and deformation resistance. At the same time, the hollow design does not affect the airflow and ventilation inside the base. The air blowing assembly 13 is positioned above the hollow reinforcing bracket 11. This assembly generates airflow through its own structure, providing ventilation to the interior of the impact-resistant base 8 and related components. This helps maintain the dryness of the base's interior and reduces the impact of moisture on the components. Anti-salt spray assemblies 14 are installed on both sides of the air blowing assembly 13. These assemblies treat the air entering the equipment, filtering out corrosive substances such as salt spray, reducing the corrosion of the transformer's internal equipment by salt spray, protecting the equipment, and extending its service life.

[0036] In a preferred embodiment, the air blowing assembly 13 includes a mounting box 131, which is installed at the center of the upper end of the hollowed-out reinforcing bracket 11. The mounting box 131 provides a stable bearing foundation for the gear transmission and corrosion-resistant fan 15 inside the assembly, ensuring the structural stability when the components work together. A first conical gear shaft 132 is installed on both sides of the bottom of the mounting box 131, and a drying fan blade 133 is installed at the bottom of the first conical gear shaft 132. The first conical gear shaft 132 transmits power through gear meshing, providing rotational driving force for the drying fan blade 133. The drying fan blade 133 is installed at the bottom of the first conical gear shaft 132 and generates directional airflow when rotating, accelerating the evaporation of water accumulated at the bottom of the anti-collision base 8 and dispersing residual droplets, maintaining a dry environment inside the base. Corrosion-resistant fans 15 are installed on both sides of the upper end of the mounting box 131, serving as the active air supply... The wind power source, the output end of the corrosion-resistant fan 15 is equipped with a connecting pipe 16, the input end of the corrosion-resistant fan 15 is connected to the mounting box 131, and the upper end of the anti-collision base 8 is equipped with an air supply pipe 17. The ends of the two sets of connecting pipes 16 away from the corrosion-resistant fan 15 are connected to the pipe body of the air supply pipe 17. The corrosion-resistant fan 15 pressurizes the filtered air and delivers it to the air supply pipe 17 through the connecting pipe 16, providing clean airflow to the inside of the transformer body 1, and driving the entire airflow circulation system. The connecting pipe 16 connects the output end of the corrosion-resistant fan 15 and the air supply pipe 17, playing a role in airflow guidance, ensuring that the pressurized clean air is efficiently delivered to the designated area. The air supply pipe 17 is installed on the upper end of the anti-collision base 8, collects the airflow of the two sets of connecting pipes 16 and delivers it evenly to the inside of the transformer body 1, ensuring that all areas inside the transformer can obtain clean air, forming a slightly positive pressure environment to block the intrusion of external pollutants.

[0037] In a preferred embodiment, the anti-salt spray component 14 includes an air inlet connecting cylinder 141, which is installed on one side of the mounting box 131. The front and rear ends of the anti-collision base 8 are both provided with mounting ports 12. The ends of the two sets of air inlet connecting cylinders 141 furthest from the mounting box 131 penetrate the inner cavity of the mounting port 12. The air inlet connecting cylinder 141 provides an independent and closed channel for external air to enter the equipment, preventing secondary pollution of the airflow during transmission. Furthermore, the design of penetrating the mounting port 12 ensures that the collected air comes from the open environment outside the transformer substation. The tubular structure of the air inlet connecting cylinder 141 guides the airflow in a directional manner. A second conical gear shaft 142 is provided at the connection between the air inlet connecting cylinder 141 and the mounting box 131. The first conical gear shaft 132 and the second conical gear shaft 142 mesh with each other. The second conical gear shaft 142 achieves power sharing through gear transmission, ensuring that the two sets of components operate at the same rhythm. A self-driving fan blade 143 is sleeved on the outer surface of the second conical gear shaft 142. The self-driving fan blade 143 is driven by airflow to rotate itself and the second conical gear shaft 142. A ratchet structure 144 is installed on one side of the self-driving fan blade 143. The ratchet structure 144 installed on one side of the self-driving fan blade 143 utilizes the characteristics of one-way locking and reverse sliding. When clockwise rotation occurs during reverse air exchange, intermittent collisions and sliding occur between the pawl and the ratchet, forming high-frequency micro-vibrations. This vibration can precisely act on the surface of the filter screen 145. The reverse airflow shakes off attached salt crystals, dust particles, and other impurities, preventing long-term accumulation and clogging of the pores. This extends the replacement cycle of the filter 145, reduces maintenance costs, and the vibration amplitude is controllable, ensuring it does not affect the structural stability of the self-driving fan blade 143 or the intake connecting cylinder 141. An insect screen 146, made of high-density metal mesh, is installed on the side of the intake connecting cylinder 141 furthest from the mounting box 131. This effectively blocks mosquitoes, willow catkins, pebbles, and other foreign objects from entering the intake connecting cylinder 141, preventing them from entangled in the self-driving fan blade 143 or clogging the filter 145. This ensures smooth operation of the internal mechanical structure of the components, making it particularly suitable for outdoor environments with many mosquitoes and debris. The insect screen 146 and the self-driving fan blade 143 are integrated into the filter 145. A filter screen 145 is installed on the opposite surface between the drive fan blades 143. The filter screen 145 is integrated by stacking activated carbon layer and fiber layer. The fiber layer can physically intercept large dust particles and water vapor condensation beads in the air, while the activated carbon layer removes the core components of salt spray in the air through adsorption, reducing the corrosion of electrical components inside the transformer from the source. The stacked structure can also increase the contact area between air and filter material, improve filtration efficiency and extend the saturation cycle of the filter screen. The two sets of anti-salt spray components 14 are set in a mirror image, which can collect air from the front and rear sides of the anti-collision base 8 at the same time, doubling the air intake and meeting the ventilation needs of the large space inside the transformer.

[0038] In a preferred embodiment, a drain outlet 9 is provided at the front of the upper end of the load-bearing base plate 7. The drain outlet 9 can quickly drain the condensate generated inside and the small amount of rainwater that seeps in. An air inlet 10 is provided at the rear of the upper end of the load-bearing base plate 7. The lower end of the air inlet 10 is connected to the air supply pipe 17, which can introduce clean air treated with anti-salt spray into the transformer body 1 to provide fresh airflow to each functional compartment and maintain internal air circulation. At the same time, it works with the air supply pipe 17 to form a directional airflow path to ensure that clean air efficiently covers key equipment. The inner cavity of both the drain outlet 9 and the air inlet 10 is provided with a filter screen 18, which can intercept dust and debris carried in the drain outlet 9 and the air inlet 10. To prevent pipe blockage and ensure smooth drainage and airflow, a high-voltage partition 5 is installed between transformer chamber 2 and high-voltage chamber 3, and a low-voltage partition 6 is installed between transformer chamber 2 and low-voltage chamber 4. The high-voltage partition 5 and low-voltage partition 6 achieve physical isolation between the two, separating the high-voltage and low-voltage equipment areas. Holes and slots for installing electrical equipment are opened on the surface. The bottom of the inner cavity of the impact-resistant base 8 is provided with a 5° slope. Electric drain valves 19 are installed on the bottom of both sides of the impact-resistant base 8. The 5° slope at the bottom of the inner cavity of the impact-resistant base 8 can guide the water to flow to both sides, accelerate the water flow to the electric drain valves 19 at the bottom, improve drainage efficiency, and prevent the base from becoming damp due to long-term water retention.

[0039] The implementation principle of this application embodiment is as follows: First, the anti-salt spray component 14 starts working. External air enters the air intake connecting cylinder 141 through the mounting ports 12 at the front and rear ends of the anti-collision base 8. During this process, the tubular structure of the air intake connecting cylinder 141 guides the airflow in a directional manner, reducing energy loss caused by airflow turbulence. The air first passes through the insect-proof net 146. The high-density metal mesh insect-proof net 146 is tightly attached to the inner wall of the connecting cylinder, completely blocking insects, willow catkins, and gravel foreign objects from entering and wrapping around the self-driving fan blade 143 or clogging the filter 145. Then the airflow passes through the filter 145. The filter 145 is composed of an activated carbon layer and a fiber layer in a stacked composite manner. The fiber layer physically intercepts large dust particles and water vapor condensation beads in the air with its fine pore structure, while the activated carbon layer adsorbs the core components of salt spray in the air through its rich microporous structure. The two layers work together. The system performs deep air purification. Simultaneously, due to the meshing of the first conical gear shaft 132 and the second conical gear shaft 142, when the air blowing assembly 13 operates, the power is precisely transmitted to the second conical gear shaft 142 through gear meshing, driving the self-driven fan blade 143 sleeved on its outer surface to rotate, further accelerating the purified air to quickly enter the mounting box 131. When the equipment periodically reverses the airflow, the self-driven fan blade 143 reverses accordingly, and the ratchet structure 144 installed on one side begins to function. Intermittent collisions and sliding occur between the pawl and the ratchet, and the resulting high-frequency micro-vibrations are transmitted to the surface of the filter screen 145 through the fan blades. Combined with the impact force of the reverse airflow, the salt crystals, dust particles and other impurities attached to the surface of the filter screen 145 are completely shaken off. The impurities are discharged from the air intake connecting cylinder 141 with the reverse airflow, realizing the efficient self-cleaning of the filter screen and ensuring that the filter screen always maintains a good permeability.

[0040] After the purified air enters the installation box 131, the installation box 131 provides a temporary storage and buffer space for the air. Then, it is drawn in by the anti-corrosion fans 15 on both sides of the upper end of the installation box 131. After the anti-corrosion fans 15 are started, they generate strong suction to pressurize the air. The pressurized air is delivered to the air supply pipe 17 through the connecting pipe 16. The pipeline route of the connecting pipe 16 has been optimized to minimize the resistance during the airflow process. The air supply pipe 17 collects the airflow delivered by the connecting pipes 16 on both sides and then delivers it evenly into the interior of the transformer body 1 through the air inlet 10 at the rear of the upper end of the load-bearing base plate 7. The airflow diffuses inside the transformer body 1, providing continuous clean air for the equipment in the transformer room 2, high voltage room 3 and low voltage room 4, so that a stable micro-positive pressure environment is formed inside the transformer. The pressure difference between the inside and outside effectively blocks the intrusion of unfiltered salt mist air and pollutants from the outside, and the internal air environment is guaranteed by continuous ventilation.

[0041] The hollowed-out reinforced bracket 11 further enhances the impact resistance of the anti-collision base 8 through its own structure. The 5° slope at the bottom of the inner cavity of the anti-collision base 8 acts as a guide, allowing accumulated water to flow to both sides under the combined action of gravity and airflow, eventually converging at the electric drain valves 19 on both sides of the bottom. An infrared liquid level sensor is located at the end of the 5° slope near the electric drain valve 19. When the water level is detected, the electric drain valve 19 automatically opens to quickly drain the accumulated water from the outside of the anti-collision base 8, preventing the base from becoming damp due to long-term water retention. Meanwhile, the first conical gear shaft 132 in the air blowing assembly 13 drives the drying fan blades 133 at the bottom to rotate at high speed during power transmission. The directional airflow generated by the rotation of the drying fan blades 133 covers all areas of the bottom of the inner cavity of the anti-collision base 8, accelerating the evaporation rate of the water at the bottom of the base. For residual tiny droplets, the air... The flow can also disperse the liquid, preventing droplets from remaining inside the anti-collision base 8 for a long time. The condensate generated inside the transformer body 1 during operation, as well as the occasional small amount of rainwater that seeps in, will collect at the front of the upper end of the load-bearing base plate 7 under the action of gravity, and then be discharged from the transformer body 1 through the drain outlet 9. The filter screen 18 installed in the inner cavity of the drain outlet 9 and the air inlet 10 respectively performs secondary filtration for the drainage and air intake processes. The filter screen 18 can effectively intercept fine dust and debris carried in the water and air, preventing these impurities from entering the pipe and causing blockage, ensuring that the drainage system and the air intake system always remain unobstructed. In addition, the high-voltage partition 5 installed between the transformer room 2 and the high-voltage room 3, and the low-voltage partition 6 installed between the transformer room 2 and the low-voltage room 4, are made of materials with excellent insulation properties to avoid mutual interference between high-voltage equipment and low-voltage equipment, and between transformers and high and low voltage equipment.

[0042] In this embodiment, the infrared liquid level sensor is a commonly used device that can be purchased directly from the market and is known to those skilled in the art. It can be customized or selected according to actual needs. Here we are only using it and have not made any structural or functional improvements to it, so we will not go into details here.

Identical components are represented by the same reference numerals. Therefore, all equivalent changes made to the structure, shape, and principle of this application should be covered within the scope of protection of this application.
