Description

Technical Field

[0001] The present invention relates to the technical field of transformer substations, in particular to a high and low voltage prefabricated transformer substation. Background Art

[0002] There are many types of substations, such as outdoor substations, indoor substations, underground substations, box-type substations, etc. Among them, box-type substations are also called prefabricated substations. With the widespread application of prefabricated substations, prefabricated cabins, as an important component, have also received widespread attention for their safety. Condensation is likely to occur inside the prefabricated cabin due to the influence of factors such as the external environment, external temperature, and installation location, which poses a potential hazard to the safe operation of the substation.

[0003] For example, in summer, the temperature difference between day and night is large, and the temperature outside the cabin gradually decreases after dusk. Regardless of whether the equipment inside the prefabricated cabin is operating normally, the temperature of the prefabricated cabin body will gradually decrease at a rate greater than the cooling rate of the air inside the cabin, resulting in the cabin surface temperature being lower than the cabin interior temperature. When the humid and hot ambient air encounters the lower temperature cabin surface, water vapor will condense to form condensation. When the equipment inside the cabin is operating normally and the cabin surface temperature is reduced, the cabin interior ambient temperature is still rising due to the heat generated by the equipment. The temperature difference between the cabin surface and the cabin environment is even greater, resulting in more condensation, especially when affected by electrical equipment with high operating heat generation. When the condensation gathers to form liquid water droplets that fall on components or mix with dust inside the equipment to produce corresponding conductive channels, it will affect the electrical insulation of the equipment, causing areas that should not be conductive to be converted into normal conductive areas, thereby causing the equipment to short-circuit.

DETAILED DESCRIPTION

[0036] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0037] Example 1

[0038] See also Figure 1 , Figure 2 , Figure 4 , Figure 5 , Figure 6 and Figure 8 The present invention provides a technical solution: a high and low voltage prefabricated substation, comprising a station body 1 and an inspection door 11, the inspection door 11 is installed on the front of the station body 1, a temperature equalizing component is arranged on the station body 1, the temperature equalizing component is used to reduce the generation of condensation, a ventilation component is arranged on the station body 1, and the ventilation component is used to dissipate heat, and a wiping component is arranged inside the station body 1, and the wiping component is used to wipe off condensation;

[0039] The temperature-averaging component includes a shell 2, which is fixedly mounted on the top of the station body 1, a bidirectional electric telescopic rod 21 is fixedly mounted on the top of the inner cavity of the shell 2, a driving block 22 is fixedly mounted on the output shaft of the bidirectional electric telescopic rod 21, a guide column 23 is movably mounted inside the driving block 22, the guide column 23 is fixedly mounted inside the shell 2, a first connecting member 24 is fixedly mounted on the bottom of the driving block 22, a driving rod 25 is movably mounted on the first connecting member 24, a second connecting member 26 is movably mounted on one end of the driving rod 25 away from the first connecting member 24, and a mounting plate 27 is fixedly mounted on the bottom of the second connecting member 26;

[0040] A power frame 28 is fixedly installed on both sides of a set of symmetrical parts of the mounting plate 27, a baffle 29 is fixedly installed on the bottom of the power frame 28, a first driving groove 210 is opened inside the station body 1, a first air guide groove 211 is opened inside the rear wall of the inner cavity of the station body 1, a through hole 212 is opened on the rear wall of the inner cavity of the station body 1, and the inner cavity of the station body 1 is connected with the first air guide groove 211 through the through hole 212;

[0041] A first fan 213 is installed in the first air guide groove 211, a drying frame 214 is fixedly installed on the upper side of the first air guide groove 211, a guide bin 215 is installed on one side of the drying frame 214, the guide bin 215 passes through the first air guide groove 211 and extends to the inner cavity of the station body 1, and a second fan 216 is fixedly installed at one end of the guide bin 215 located in the inner cavity of the station body 1;

[0042] The baffle 29 is above the through hole 212. When the baffle 29 is driven to the lowermost side, the through hole 212 is inside the baffle 29. A rock wool board 217 is provided inside the rear wall of the station body 1. The rock wool board 217 is between the inner cavity of the station body 1 and the first air guide groove 211. A hollow groove is provided on the surface of the drying frame 214. A desiccant is provided inside the drying frame 214. The hollow groove on the surface of the drying frame 214 is in contact with the guide bin 215.

[0043] When installing the electrical equipment inside the substation, it is necessary to align the heat dissipation slot of the electrical equipment with the through hole 212;

[0044] In the summer evening, the bidirectional electric telescopic rod 21 is started intermittently, so that the bidirectional electric telescopic rod 21 drives the driving block 22, and the driving block 22 drives the driving rod 25, so that the driving rod 25 drives the mounting plate 27 downward, and when the mounting plate 27 moves downward, it can drive the power frame 28 to move downward, so that the baffle 29 moves downward, and then the baffle 29 blocks the through hole 212. Since the bidirectional electric telescopic rod 21 is started intermittently, the baffle 29 will reciprocate up and down, intermittently blocking the through hole 212, and at the same time start the first fan 213 and the second fan 216;

[0045] When the first fan 213 is started, the heat emitted by the electrical equipment will be drawn into the first air guide slot 211 along with the air. The temperature outside the first air guide slot 211 is lower than the temperature inside the first air guide slot 211. At this time, the hot air in the first air guide slot 211 will be cooled, and the cooled air will be guided by the second fan 216 and then flow out from the guide bin 215. At this time, the temperature of the outflowing air is relatively low, which can dissipate the heat of the electrical equipment and make the temperature of the inner cavity of the station body 1 uniform, so that the temperature of the inner cavity of the station body 1 is close to the temperature outside the station body 1. By reducing the temperature difference between the inside and outside of the station body 1, the amount of condensation generated can be reduced.

[0046] It should be noted that the hot air is cooled by the temperature outside the station body 1 in the first air guide slot 211, which will cause condensation on the inner wall of the first air guide slot 211. The condensation on the inner wall of the first air guide slot 211 will be dried by the airflow intermittently flowing into the first air guide slot 211, resulting in water vapor in the airflow. Therefore, a desiccant needs to be placed in the drying frame 214 to dry the air.

[0047] The baffle 29 intermittently blocks the through hole 212 because the temperature of the air flow discharged from the guide chamber 215 is lower than the temperature of the inner cavity of the station body 1. Therefore, when it directly dissipates heat to the electrical equipment, water vapor may be generated on the surface of the electrical equipment. The intermittent heat dissipation can allow the heat of the electrical equipment itself to dry the water vapor, preventing the continuous accumulation of water vapor and causing condensation. At the same time, it also reduces the water vapor processing load of the drying frame 214, preventing the drying frame 214 from being overloaded, causing the air with water vapor to enter the inner cavity of the station body 1 and generate condensation.

[0048] Example 2

[0049] See also Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 6 , Fig. 9 and Fig.10 The ventilation assembly includes a heat insulation layer 3, which is arranged above the inner cavity of the station body 1. A drive frame 31 is fixedly installed on the front of the drive block 22, and a piston plate 32 is fixedly installed on one end of the drive frame 31 away from the drive block 22. The width of the heat insulation layer 3 is equal to the length of the piston plate 32, and the height of the heat insulation layer 3 is equal to the height of the piston plate 32;

[0050] A second driving groove 33 adapted to the driving frame 31 is provided on the top of the station body 1, and a second air guide groove 34 is provided on a group of symmetrical sides and the middle of the inner cavity of the station body 1, and the heat insulation layer 3 is connected with the inner cavity of the station body 1 through the second air guide groove 34;

[0051] The heat insulation layer 3 is divided into two side spaces and a middle space by two piston plates 32, and the third air guide grooves 35 are provided above the two side spaces and the middle space, and the second air guide grooves 34 are provided at the bottom of the three spaces respectively. An air guide frame 36 is fixedly installed on the top of the station body 1, and the third air guide grooves 35 are located on the inner side of the air guide frame 36. A cover plate 37 is hinged on the top of the air guide frame 36, and micropores are provided on the surface of the cover plate 37. An elastic rope 38 is fixedly connected to one side of the cover plate 37, and one end of the elastic rope 38 away from the cover plate 37 is fixedly connected to the top of the station body 1. A water storage tank 39 is fixedly installed inside the heat insulation layer 3;

[0052] The length and width of the inner cavity of the water storage box 39 are both greater than the length and width of the bottom of the third air guide slot 35 , and the water storage box 39 is located directly below the third air guide slot 35 .

[0053] On the basis of Example 1, when the driving block 22 is driven, the driving frame 31 is driven to move, so that the driving frame 31 drives the piston plate 32 to move inward. When the piston plate 32 moves inward, under the influence of negative pressure, the two side spaces inside the heat insulation layer 3 will inhale air from the inner cavity of the station body 1 and the outside of the station body 1 through the second air guide groove 34 and the micropores on the cover plate 37, so that the air inside and outside the station body 1 is evenly cooled and heated in the heat insulation layer 3;

[0054] As the driving block 22 is reset, the second air guide groove 34 will also be reset. At this time, part of the air in the side space will be discharged from the third air guide groove 35, and the discharged airflow will break the cover plate 37 and enter the outside of the station body 1, so that air exchange can be achieved and the temperature of the inner cavity of the station body 1 is dissipated, and another part of the air will be re-introduced into the inner cavity of the station body 1 by the second air guide groove 34. At this time, the temperature of the mixed air is between the air temperatures inside and outside the station body 1, so that the temperature of the inner cavity of the station body 1 is closer to the temperature outside the station body 1, thereby reducing the temperature difference and further reducing the probability of condensation.

[0055] Furthermore, the negative pressure effects generated by the side space and the middle space inside the heat insulation layer 3 are opposite. When the side space inhales air, the middle space discharges air. Under the influence of the kinetic energy of the air, the air in the inner cavity of the station body 1 will flow, so that the hotter air in the inner cavity of the station body 1 is mixed with the cooler air introduced after being cooled, so that the air in the inner cavity of the station body 1 can descend evenly, avoiding the problem of condensation caused by local heat and local cold inside the station body 1.

[0056] Furthermore, due to the presence of micropores on the cover plate 37, the air sucked into the heat insulation layer 3 includes more air in the inner cavity of the station body 1 and less air sucked from the outside of the station body 1, so the temperature of the mixed air is closer to the temperature of the inner cavity of the station body 1, thereby preventing the mixed air from entering the inner cavity of the station body 1, causing the temperature of the inner cavity of the station body 1 to change rapidly and generate condensation;

[0057] In addition, the intermittent operation of the bidirectional electric telescopic rod 21 can also reduce the frequency of air exchange inside and outside the station body 1, so that the airflow in the inner cavity of the station body 1 can be mixed more fully and evenly, further avoiding the problem of condensation caused by local cold and hot in the inner cavity, and cooperating with the heat dissipation of the electrical equipment by the guide bin 215 in Example 1, it can also prevent the problem of condensation caused by the temperature of the electrical equipment being higher than the ambient temperature of the inner cavity of the station body 1 after the inner cavity of the station body 1 is cooled down, further avoiding the generation of condensation, but it should be noted that the temperature of the inner cavity of the station body 1 cannot be too much lower than the temperature of the electrical equipment itself, so as to prevent condensation from being generated on the surface of the electrical equipment;

[0058] On the other hand, when the mixed air in the heat insulation layer 3 is discharged from the third air guide groove 35, condensation may be generated in the third air guide groove 35 because the temperature outside is lower than the discharge temperature. In addition, on rainy days, rainwater may also enter the heat insulation layer 3 through the micropores on the cover plate 37. At this time, the water storage tank 39 can be used to collect the fallen condensation and rainwater to prevent rainwater from flowing into the inner cavity of the station body 1 from the second air guide groove 34.

[0059] During installation, it is necessary to install drain pipes at the upper and lower positions of the inner cavity of the water storage tank 39, and extend the drain pipes to the outside of the station body 1. In summer, close the lower drain pipe and open the upper drain pipe to prevent the water in the inner cavity of the water storage tank 39 from overflowing and flowing out. At the same time, there is still water on the lower side of the upper drain pipe in the water storage tank 39. When the temperature is high during the day, the thermal insulation effect of the thermal insulation layer 3 can be improved by evaporation of water. In winter, open the lower drain pipe to fully drain the water and avoid the generation of water vapor.

[0060] Example 3

[0061] See also Figure 3 , Figure 4 , Figure 6 , Figure 7 , Fig. 9 and Fig.11 The wiping assembly includes a connecting block 4, which is fixedly mounted on the bottom of the piston plate 32. A first wiping member 41 is fixedly mounted on the bottom of the connecting block 4. A set of symmetrical two sides of the first wiping member 41 are provided with mounting grooves 42. A rubber elastic column 43 is fixedly connected to the mounting groove 42. The other end of the rubber elastic column 43 is fixedly connected to a second wiping member 44. A third driving groove 45 adapted to the connecting block 4 is provided at the bottom of the inner cavity of the station body 1.

[0062] A guide plate 47 is fixedly installed on the top of the inner cavity of the station body 1, and the number of guide plates 47 is two, and the two guide plates 47 are respectively located on the left and right sides of the inner cavity of the station body 1, and the guide plates 47 are located below the second air guide grooves 34 on the two sides, and there is a distance between the guide plates 47 and the side wall of the inner cavity of the station body 1;

[0063] A fourth air guide slot 46 is provided in the middle space of the heat insulation layer 3 . The fourth air guide slot 46 is designed to be inclined, and the inclined direction is from the rear side of the inner cavity of the station body 1 to the front side and inclined downward.

[0064] If the temperature difference between the inside and outside of the station body 1 changes too quickly, it will be difficult for Embodiment 1 and Embodiment 2 to fully and timely reduce the condensation, resulting in some condensation still being generated on the top and four walls of the inner cavity of the station body 1;

[0065] On the basis of Example 2, when the piston plate 32 moves, it will drive the connecting block 4 to move in the third driving groove 45, so that the connecting block 4 drives the first wiping member 41 to move, thereby wiping the condensation on the top of the inner cavity of the station body 1. Since the stroke of the piston plate 32 is limited, the first wiping member 41 can only wipe the condensation on the top of the inner cavity of the station body 1.

[0066] When the first wiping member 41 reaches the maximum stroke and stops, under the action of inertia, the second wiping member 44 in the moving direction will continue to move and stretch the rubber elastic column 43, thereby increasing the wiping stroke and improving the dew removal effect on the top of the inner cavity of the station body 1;

[0067] The airflow in the second air guide slot 34 can be guided by the guide plate 47, so that after the airflow hits the second air guide slot 34, it moves in different directions, one part of which acts on the side wall of the inner cavity of the station body 1 to dry and remove the condensation generated on the side wall, and another part of which acts on the top of the inner cavity of the station body 1 to remove the condensation on the top more comprehensively, thereby improving the dew removal effect;

[0068] On the other hand, part of the airflow will act on the first wiping piece 41 and the second wiping piece 44 to dry the first wiping piece 41 and the second wiping piece 44, thereby improving the water absorption effect of the first wiping piece 41 and the second wiping piece 44, thereby further improving the dew removal effect. Through the action of the guide plate 47, part of the airflow discharged from the insulation layer 3 will act on the front wall of the inner cavity of the station body 1 to dry the condensation produced on its surface.

[0069] Example 4

[0070] See also Figures 2 to 4 A moisture-proof layer 5 is provided at the bottom of the station body 1 , and fifth air guide grooves 51 are provided inside the side walls of the station body 1 . The heat insulation layer 3 and the moisture-proof layer 5 are connected through the moisture-proof layer 5 .

[0071] When the project site is in a pothole area, moisture can easily enter the interior through the bottom of the station body 1, thereby increasing the relative humidity of the internal environment of the station body 1, causing condensation to easily occur;

[0072] By placing a desiccant in the moisture-proof layer 5, moisture that penetrates into the inner cavity from the bottom of the station body 1 can be dried. In addition, the fifth air guide groove 51 can be used to introduce part of the airflow derived from the side space of the insulation layer 3 into the moisture-proof layer 5 and air-dry the interior. In this way, the moisture that penetrates into the moisture-proof layer 5 can be further dried, reducing the probability of condensation.
