Temperature adjusting device for box-type substation

Abstract

The invention relates to the technical field of box-type substations, and discloses a temperature adjusting device for a box-type substation. When the temperature in the box body is too high, cold air generated by the evaporator flows in the box body through the air pump so as to adjust the temperature in the box body, and when the humidity in the box body is high, the ventilation plate rotates to be opened so that the interior of the box body can communicate with the exterior of the box body. Natural wind outside the box body penetrates through the position of the ventilation plate to conduct ventilation on air in the box body so as to adjust the humidity in the box body, and therefore during long-time operation of the box-type transformer substation, automatic adjustment can be conducted when the internal temperature is increased after internal equipment operates and generates heat or the internal humidity is increased by water vapor in the air, and the working efficiency of the box-type transformer substation is improved. Especially in relatively severe environments such as gobi, desert and the like, equipment operation faults caused by relatively high temperature or relatively high humidity are effectively avoided, the operation stability of the box-type substation is improved, and the service life of the equipment is prolonged.

Description

Technical Field

[0001] This invention relates to the field of prefabricated substation technology, specifically a temperature regulation device for prefabricated substations. Background Technology

[0002] A prefabricated substation, also known as a prefabricated transformer substation, is a factory-prefabricated, compact indoor / outdoor power distribution unit that integrates high-voltage switchgear, distribution transformers, and low-voltage power distribution equipment according to a specific wiring scheme. It organically combines transformer voltage reduction and low-voltage power distribution functions, all housed in a moisture-proof, rust-proof, dust-proof, rodent-proof, fire-proof, theft-proof, heat-insulated, and movable steel structure box. It represents a new type of substation that has emerged after traditional civil engineering substations. Especially in renewable energy power plants located in environments such as the Gobi Desert, deserts, and beaches, where there is prolonged exposure to sunlight, limited equipment space, complex load conditions, and harsh operating conditions, the demand for temperature-controlled prefabricated substations is even higher.

[0003] In existing prefabricated substations, such as Chinese patent CN119787154B, an intake fan draws air from outside the substation body through a first filter and an intake pipe into the substation body. The original air inside the substation body is then discharged through an exhaust structure. When cleaning dust from the first filter is required, an adjustment mechanism drives a sealing cover to move. The sealing cover then drives a pusher to move below the first filter, which in turn pushes the filter to slide from the clearance hole into the intake pipe. The pusher then stops supporting the filter, and an elastic support moves the filter down to its lowest position, causing the dust at the bottom of the filter to fall off. When ventilation and heat dissipation are not required within the substation body, the adjustment mechanism drives the sealing cover to seal the clearance hole, allowing the dust adsorbed on the first filter to be cleaned without affecting ventilation efficiency and ensuring that heat dissipation efficiency remains within a preset range. However, the following problems still exist: the design of the prefabricated substation is relatively sealed and insulated. With long-term operation, the heat generated by the internal equipment will be locked inside the prefabricated substation, resulting in a high overall temperature after long-term operation. The high temperature will make the equipment prone to failure and reduce the service life of the equipment.

[0004] However, the following problems still exist: the design of the prefabricated substation is relatively sealed and insulated. With long-term operation, the heat generated by the internal equipment will be locked inside the prefabricated substation. Especially in relatively harsh environments, the temperature will rise more rapidly after long-term operation. The higher temperature will make the equipment more prone to failure and reduce the service life of the equipment. Summary of the Invention

[0016] Compared with the prior art, the present invention provides a temperature regulation device for prefabricated substations, which has the following advantages: 1. This temperature regulation device for prefabricated substations works by installing the prefabricated substation at the required location. It utilizes the substation mechanism to convert high-voltage electricity to low-voltage electricity for transmission. With prolonged use, due to the prefabricated substation's sealed design, internal heat generation, and moisture in the air, the temperature and humidity inside the prefabricated substation can become excessively high. When the internal temperature becomes too high, the evaporator generates cool air. Simultaneously, an air pump is moved to a position opposite the evaporator. The air pump draws air from one side of the prefabricated substation and blows it onto the evaporator on the other side. The air pump circulates the cool air generated by the evaporator within the prefabricated substation, thereby regulating the temperature and humidity inside the subfabricated substation. When the humidity is high, move the air pump to the side of the enclosure. Once the air pump is on the side, it triggers the ventilator. The ventilator rotates and opens, connecting the inside of the enclosure with the outside. Natural air from outside passes through the ventilator to circulate and exchange air inside the enclosure, thereby adjusting the humidity inside. This allows for automatic adjustment during long-term operation of the prefabricated substation when internal equipment generates heat, increasing the internal temperature, or when moisture in the air increases the internal humidity. Especially in relatively harsh environments such as the Gobi Desert, this effectively prevents equipment malfunctions caused by high temperatures or high humidity, improving the stability of the prefabricated substation and extending the service life of the equipment.

[0017] 2. This temperature adjustment device for prefabricated substations, through the setting of the support grid frame and the use of the ventilation holes on the support grid frame, allows the adjustment mechanism on the support grid frame to be connected to the high-voltage chamber, low-voltage chamber, and transformer chamber, so that the adjustment mechanism can stably adjust the overall temperature and humidity of the high-voltage chamber, low-voltage chamber, and transformer chamber, thereby improving the processing efficiency of the adjustment mechanism.

[0018] 3. This temperature regulation device for prefabricated substations protects the condenser by covering it with a protective casing. The condenser dissipates heat through the vents on the protective casing, thereby improving the stability of equipment operation and extending the service life of the prefabricated substation.

[0021] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. 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 are within the scope of protection of the present invention.

[0022] As described in the background section, there are shortcomings in the existing technology. In order to solve the above-mentioned technical problems, this application proposes a temperature regulation device for prefabricated substations.

[0023] Example 1, a typical implementation of this application, such as Figure 1 As shown, a temperature adjustment device for a prefabricated substation includes a housing 1, a substation mechanism 2 disposed within the housing 1, and an adjustment mechanism 3 disposed within the housing 1. The substation mechanism 2 is disposed within the housing 1 and is a transformer structure used for transformer conversion. The adjustment mechanism 3 includes a vent plate 313, an air pump 316, and an evaporator 319. Ventilation plates 313 are provided on both sides of the housing 1, and the vent plates 313 penetrate the wall of the housing 1. An air pump 316 is provided inside the housing 1 and moves linearly inside the housing 1. An evaporator 319 is provided inside the housing 1 and generates cold air using the refrigeration principle. When adjusting the temperature inside the housing 1, the air pump 316 moves linearly to the point where the distance to the corresponding evaporator 319 is shortest, and the air pump 316 blows the cold air generated by the evaporator 319 towards the bottom of the housing 1. When adjusting the humidity inside the housing 1, the air pump 316 moves linearly to the side of the housing 1, causing the air pump 316 to trigger the vent plate 313 to open.

[0024] When using this invention: After the prefabricated substation is installed at the required location, it is put into use. The substation mechanism 2 converts high-voltage electricity into low-voltage electricity for transmission. With prolonged use, due to the prefabricated substation's sealed design, internal heat generation, and moisture in the air, the temperature and humidity inside the enclosure 1 become excessively high. When the temperature inside enclosure 1 becomes too high, the evaporator 319 is activated, generating cool air. Simultaneously, the air pump 316 is moved to a position opposite the evaporator 319. The air pump 316 draws air from one side of enclosure 1 and blows it onto the evaporator 319 on the other side of enclosure 1. The air pump 316 circulates the cool air generated by the evaporator 319 within enclosure 1, thereby adjusting the temperature and humidity inside enclosure 1. When the humidity is high, the air pump 316 is moved to the side of the enclosure 1. After the air pump 316 is moved to the side of the enclosure 1, it triggers the ventilation plate 313 to open. The ventilation plate 313 rotates and opens, connecting the inside of the enclosure 1 with the outside. Natural wind from outside the enclosure 1 passes through the ventilation plate 313 to circulate and exchange air inside the enclosure 1, thereby adjusting the humidity inside the enclosure 1. Thus, during the long-term operation of the prefabricated substation, when the internal temperature is increased due to heat generated by the internal equipment or when the internal humidity is increased due to moisture in the air, the system can automatically adjust. Especially in relatively harsh environments such as the Gobi Desert, this effectively avoids equipment malfunctions caused by high temperature or high humidity, improves the stability of the prefabricated substation operation, and extends the service life of the equipment.

[0025] Example 2, as Figures 2-5 As shown, the difference from the above embodiment is that the substation mechanism 2 includes a high-voltage chamber 21. The high-voltage chamber 21 is provided on one side of the enclosure 1. The enclosure 1 is provided with a first opening and closing door. The first opening and closing door of the enclosure 1 is adjacent to the high-voltage chamber 21.

A low-pressure cabinet 24 is fixedly installed in the low-pressure chamber 23. The low-pressure cabinet 24 is used to control the connection of the low-pressure end.

[0027] Furthermore, a transformer chamber 25 is provided inside the enclosure 1. A third door is provided on the enclosure 1.

The transformer chamber 25 is located between the high-voltage chamber 21 and the low-voltage chamber 23. A partition plate is provided between the transformer chamber 25 and the high-voltage chamber 21, and a partition plate is provided between the transformer chamber 25 and the low-voltage chamber 23. A transformer 26 is fixedly installed inside the transformer chamber 25. The high-voltage end of the transformer 26 is electrically connected to the high-voltage cabinet 22, and the low-voltage end of the transformer 26 is electrically connected to the low-voltage cabinet 24.

[0028] When using a prefabricated substation, place it at the desired installation location and install it. Then, electrically connect the high-voltage cabinet 22 in the high-voltage compartment 21 to the high-voltage end of the transformer 26 in the transformer compartment 25. Next, electrically connect the low-voltage cabinet 24 in the low-voltage compartment 23 to the low-voltage end of the transformer 26 in the transformer compartment 25. Finally, connect the high-voltage cabinet 22 to the high-voltage transmission network and the low-voltage cabinet 24 to the community circuit.

The support frame 31 is provided with multiple ventilation holes. A temperature detector 32 is fixedly installed on the support frame 31 for detecting the temperature inside the housing 1. A humidity detector 33 is fixedly installed on the support frame 31 for detecting the humidity inside the housing 1.

[0030] Furthermore, a rail frame 34 is fixedly installed at the top of the box 1. The length of the rail frame 34 is adapted to the length of the box 1. The rail frame 34 is located above the supporting grid frame 31. A sliding member 35 is slidably fitted on the rail frame 34. The sliding member 35 is located below the rail frame 34. A screw 36 is rotatably fitted inside the box 1. The screw 36 is located in the rail frame 34. The screw 36 passes through the sliding member 35. The screw 36 and the sliding member 35 are threadedly fitted. The length of the screw 36 is adapted to the length of the rail frame 34.

[0031] Furthermore, a servo motor 37 is fixedly installed on the support frame 31, a first pulley 38 is fixedly installed on the shaft of the servo motor 37, a second pulley 39 is sleeved on the screw 36, the second pulley 39 and the first pulley 38 are located on the same vertical plane, and a toothed belt 310 is tensioned on the second pulley 39 and the first pulley 38. The toothed belt 310 meshes with the first pulley 38 and the second pulley 39.

[0032] Furthermore, extension rods 311 are fixedly installed on both sides of the bottom end of the sliding member 35, and the extension rods 311 extend to both sides of the sliding member 35 respectively. Trigger controllers 312 are fixedly installed on both inner walls of the box body 1. The trigger controllers 312 are located above the support frame 31 and are at the same height as the extension rods 311. Multiple ventilation plates 313 are rotatably fitted on the upper ends of both sides of the box body 1. The ventilation plates 313 are used to control the communication between the inside and outside of the box body 1. Multiple stepper motors 314 are fixedly installed on the box body 1. Each stepper motor 314 is poweredly connected to each ventilation plate 313. The stepper motors 314 are signal connected to the trigger controllers 312. Multiple fans 315 are fixedly installed on both sides of the support frame 31. Each fan 315 is adjacent to each ventilation plate 313.

[0033] Furthermore, an air pump 316 is fixedly installed at the bottom of the sliding member 35. The air pump 316 is located between the extension rods 311 on both sides. An air inlet pipe 317 is fixedly installed on one side of the air pump 316 and is connected to the air pump 316. An air outlet pipe 318 is fixedly installed on the other side of the air pump 316 and is connected to the air pump 316.

[0034] Furthermore, an evaporator 319 is fixedly installed on the support frame 31, a compressor 320 is fixedly installed on the support frame 31, a condenser 321 is fixedly installed on the top of the housing 1, the evaporator 319 is connected to the compressor 320, the evaporator 319 is connected to the condenser 321, and the compressor 320 is connected to the condenser 321.

[0035] Furthermore, a protective shell is fitted over the condenser 321 to protect it. The protective shell has vent holes, through which the condenser 321 dissipates heat.

[0036] During the temperature adjustment process inside the prefabricated substation, the temperature detector 32 detected a high temperature inside the enclosure 1, activating the servo motor 37. The servo motor 37 drives the first pulley 38 to rotate, which in turn drives the toothed belt 310 to rotate. The toothed belt 310 then drives the second pulley 39 to rotate, which in turn drives the screw 36 to rotate. The screw 36 drives the sliding member 35 to move on the rail frame 34, which in turn moves the air pump 316, aligning the air outlet pipe 318 on the air pump 316 with the evaporator. 319. Start the compressor 320. The compressor 320 drives the refrigerant in the refrigeration pipeline formed by the compressor 320, condenser 321 and evaporator 319 to circulate, so that the evaporator 319 produces cold air and the condenser 321 dissipates heat. Start the air pump 316. The air pump 316 draws gas from the air inlet pipe 317 and discharges it from the air outlet pipe 318, so that the gas is blown towards the evaporator 319. The cold air produced by the evaporator 319 is blown into the interior of the cabinet 1, thereby adjusting the temperature inside the cabinet 1. When adjusting the humidity inside the prefabricated substation, the humidity detector 33 detects that the humidity inside the box 1 is high. The movement of the sliding member 35 drives the extension rod 311 to move, so that the extension rod 311 touches the trigger controller 312. The trigger controller 321 controls the stepper motor 314 to start, and the stepper motor 314 drives the ventilation plate 313 to rotate, so that the ventilation plate 313 opens the connection between the inside and outside of the box 1. The external natural wind passes through the position of the ventilation plate 313 to pass through the inside of the box 1, thereby adjusting the humidity inside the box 1.

[0037] Working principle of the invention: After the prefabricated substation is installed at the required location, it is put into use. The substation mechanism 2 converts high-voltage electricity into low-voltage electricity for transmission. With prolonged use, due to the prefabricated substation's sealed design, internal heat generation, and moisture in the air, the temperature and humidity inside the enclosure 1 become excessively high. When the temperature inside enclosure 1 becomes too high, the evaporator 319 is activated, generating cool air. Simultaneously, the air pump 316 is moved to a position opposite the evaporator 319. The air pump 316 draws air from one side of enclosure 1 and blows it onto the evaporator 319 on the other side of enclosure 1. The air pump 316 circulates the cool air generated by the evaporator 319 within enclosure 1, thereby adjusting the temperature and humidity inside enclosure 1. When the humidity is high, the air pump 316 is moved to the side of the enclosure 1. After the air pump 316 is moved to the side of the enclosure 1, it triggers the ventilation plate 313 to open. The ventilation plate 313 rotates and opens, connecting the inside of the enclosure 1 with the outside. The natural wind outside the enclosure 1 passes through the ventilation plate 313 to circulate and exchange the air inside the enclosure 1, thereby adjusting the humidity inside the enclosure 1. In the long-term operation of the prefabricated substation, when the internal equipment generates heat and increases the internal temperature or when the moisture in the air increases the internal humidity, it can be automatically adjusted. Especially in relatively harsh environments such as the Gobi Desert, it can effectively prevent high temperature or high humidity from causing equipment failure, improve the stability of the prefabricated substation operation, and extend the service life of the equipment. When using a prefabricated substation, place the prefabricated substation at the required installation location and install it. Then, electrically connect the high-voltage cabinet 22 in the high-voltage compartment 21 to the high-voltage end of the transformer 26 in the transformer compartment 25. Then, electrically connect the low-voltage cabinet 24 in the low-voltage compartment 23 to the low-voltage end of the transformer 26 in the transformer compartment 25. Finally, connect the high-voltage cabinet 22 to the high-voltage transmission network and the low-voltage cabinet 24 to the community circuit. This completes the installation of the prefabricated substation. When adjusting the temperature inside the prefabricated substation, the temperature detector 32 detects that the temperature inside the enclosure 1 is too high, and the servo motor 37 is started. The servo motor 37 drives the first pulley 38 to rotate, the first pulley 38 drives the toothed belt 310 to rotate, the toothed belt 310 drives the second pulley 39 to rotate, the second pulley 39 drives the screw 36 to rotate, the screw 36 drives the sliding member 35 to move on the rail frame 34, and the sliding member 35 drives the air pump 316 to move, so that the air outlet pipe 318 on the air pump 316 is aligned with the evaporator 31. 9. Start the compressor 320. The compressor 320 drives the refrigerant in the refrigeration pipeline formed by the compressor 320, condenser 321 and evaporator 319 to circulate, so that the evaporator 319 produces cold air and the condenser 321 dissipates heat. Start the air pump 316. The air pump 316 draws gas from the air inlet pipe 317 and discharges it from the air outlet pipe 318, so that the gas is blown towards the evaporator 319. The cold air produced by the evaporator 319 is blown into the interior of the cabinet 1, thereby adjusting the temperature inside the cabinet 1. When adjusting the humidity inside the prefabricated substation, the humidity detector 33 detects that the humidity inside the box 1 is high. The movement of the sliding member 35 drives the extension rod 311 to move, so that the extension rod 311 touches the trigger controller 312. The trigger controller 321 controls the stepper motor 314 to start, and the stepper motor 314 drives the ventilation plate 313 to rotate, so that the ventilation plate 313 opens the connection between the inside and outside of the box 1. The external natural wind passes through the position of the ventilation plate 313 to pass through the inside of the box 1, thereby adjusting the humidity inside the box 1.
