Description

Technical Field

[0001] This application relates to the technical field of prefabricated substations, and more particularly to a prefabricated substation structure. Background Technology

[0002] A box-type substation typically refers to a box-type substation, whose main function is to convert high-voltage electrical energy into low-voltage electrical energy and distribute the electrical energy to various electrical devices through a low-voltage power distribution network.

[0003] In related technologies, a prefabricated substation includes a box and multiple electronic devices installed inside the box. The box has multiple ventilation openings, and the electronic devices inside the box are used to achieve low-voltage power distribution.

[0004] However, during the operation of electronic components, they will gradually generate heat and cause the temperature inside the enclosure to rise. At this time, relying solely on the natural airflow at the ventilation openings will easily result in poor overall heat dissipation of the transformer. Utility Model Content

[0005] This application provides a prefabricated transformer structure to solve the problem of excessively high overall operating temperature of prefabricated transformers due to poor overall heat dissipation in the prior art.

[0006] To achieve the above objectives, the embodiments of this application provide the following technical solutions:

[0007] This application provides a prefabricated transformer structure, including a housing with ventilation openings and a heat dissipation assembly. The heat dissipation assembly includes a protective enclosure and a blower. The protective enclosure is movably mounted on the housing and has multiple ventilation holes. Some of the ventilation holes connect the interior of the protective enclosure to the interior of the housing, while others connect the interior of the protective enclosure to the exterior of the housing. The blower is disposed inside the protective enclosure to control airflow into and out of the housing.

[0008] In one possible implementation, the side of the enclosure has an installation opening, and the protective enclosure is slidably disposed within the installation opening along the opening direction of the installation opening.

[0009] In one possible implementation, the housing is provided with a connecting frame, and the outer wall of the protective housing has multiple sets of connecting holes, each set of connecting holes being distributed along the sliding direction of the protective housing, and the connecting frame being provided with fasteners that mate with each of the connecting holes in the same set.

[0010] In one possible implementation, the connection hole is located on the side of the protective box.

[0011] In one possible implementation, a drainage groove is provided on the lower surface of the connection hole, one end of which extends downward at an angle and connects to the outer surface of the protective box.

[0012] In one possible implementation, the ventilation hole connecting the interior of the protective box to the exterior of the box is located on the side of the protective box away from the interior of the box, and the opening of this part of the ventilation hole away from the box has an inclined downward structure.

[0013] In one possible implementation, the protective enclosure is provided with a filter screen that extends into the enclosure and is used to filter the airflow flowing within the enclosure.

[0014] In one possible implementation, the protective box has an opening on one side, the filter screen has a connecting strip at one end, the end of the filter screen away from the connecting strip is inserted into the protective box from the opening, and the connecting strip is detachably connected to the protective box.

[0015] In one possible implementation, the socket is located on the lower surface of the protective box.

[0016] In one possible implementation, the heat dissipation assembly further includes a temperature sensor electrically connected to the blower, the temperature sensor being disposed within the housing, the temperature sensor being used to detect the temperature within the housing, and controlling the blower to operate when the temperature reaches a preset value.

[0017] This application provides a prefabricated substation structure with a housing containing ventilation openings and a heat dissipation assembly. The heat dissipation assembly includes a protective enclosure and a blower. The protective enclosure is movably mounted on the housing and has multiple ventilation holes. Some ventilation holes connect the interior of the protective enclosure to the interior of the main housing, while others connect the interior of the protective enclosure to the exterior. The blower is located inside the protective enclosure to control airflow into and out of the housing. Therefore, in use, activating the blower increases the airflow speed within the protective enclosure, effectively increasing the airflow speed between the interior and exterior of the housing. Simultaneously, the airflow at the ventilation openings enhances the circulation of airflow between the interior and exterior of the housing, effectively increasing the overall heat dissipation of the substation. Furthermore, during actual installation, the position of the protective enclosure can be adjusted according to actual needs, improving the overall adaptability of the heat dissipation assembly installation and solving the problem of excessively high operating temperatures in existing prefabricated substations due to poor overall heat dissipation.

[0032] To make the objectives, technical solutions, and advantages of this application clearer, the technical solutions of this application and how they solve the aforementioned technical problems will be clearly and completely described below with reference to specific embodiments and the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this application, not all of them. The following specific embodiments can be combined with each other, and the same or similar concepts or processes may not be described again in some embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0033] The terms “first,” “second,” “third,” “fourth,” etc. (if present) in the specification, claims, and accompanying drawings of this application are used to distinguish similar objects and are not necessarily used to describe a particular order or sequence. It should be understood that such data can be interchanged where appropriate so that the embodiments of this application described herein can be implemented, for example, in orders other than those illustrated or described herein.

[0034] In this application, the terms "exemplary" or "for example" are used to indicate examples, illustrations, or descriptions. Any embodiment or design described as "exemplary" or "for example" in this application should not be construed as being more preferred or advantageous than other embodiments or designs. Specifically, the use of terms such as "exemplary" or "for example" is intended to present the relevant concepts in a specific manner.

[0035] In related technologies, the prefabricated substation includes a box and multiple electronic devices installed inside the box. The box has multiple ventilation openings to achieve low-voltage power distribution through the electronic devices inside the box. At the same time, airflow can circulate naturally at the ventilation openings to ensure a certain ventilation effect inside the box.

[0036] However, during the operation of electronic components, they gradually generate heat, leading to a high temperature inside the enclosure. At this time, relying solely on the natural airflow at the ventilation openings can result in poor overall heat dissipation of the transformer, thereby threatening the safe and stable operation of the transformer.

[0037] Therefore, this application provides a prefabricated substation structure with ventilation openings and heat dissipation components on the enclosure. The heat dissipation components include a protective box and a blower. The protective box is movably mounted on the enclosure and has multiple ventilation holes. Some ventilation holes connect the protective box to the interior of the enclosure, while others connect it to the exterior. The blower is located inside the protective box. Thus, in use, turning on the blower increases the airflow speed within the protective box, effectively increasing the airflow speed between the interior and exterior of the enclosure. Simultaneously, the airflow at the ventilation openings enhances the circulation of airflow between the interior and exterior of the enclosure, effectively increasing the overall heat dissipation of the prefabricated substation. Furthermore, during actual installation, the position of the protective box can be adjusted according to actual needs, improving the overall adaptability of the heat dissipation components and solving the problem of excessively high overall operating temperature of the prefabricated substation due to poor overall heat dissipation in existing technologies.

[0038] The technical solution of this utility model will now be described in detail with reference to the accompanying drawings and specific embodiments. The following specific embodiments can be combined with each other, and the same or similar concepts or processes may not be described again in some embodiments.

[0039] like Figure 1 As shown, this application embodiment provides a prefabricated transformer structure, including a housing 100, the housing 100 being provided with a ventilation opening 110 and a heat dissipation assembly 200; the heat dissipation assembly 200 includes a protective box 210 and a blower 220, the protective box 210 being movably mounted on the housing 100, the protective box 210 having multiple ventilation holes 211, some of the ventilation holes 211 connecting the interior of the protective box 210 to the interior of the housing 100, and other ventilation holes 211 connecting the interior of the protective box 210 to the exterior of the housing 100; the blower 220 being disposed inside the protective box 210, so as to control the airflow through the protective box 210 into / out of the housing 100.

[0040] Specifically, the transformer substation structure includes a housing 100 and electronic devices disposed within the housing 100. The electronic devices can be related equipment in the prior art, such as transformers, relays, switches, measuring instruments, communication equipment, etc., and there are no restrictions on them. Furthermore, the electronic devices are not specifically illustrated in this embodiment.

[0041] It is understood that the box 100 includes a main body 120 with an opening on one side and a door 130 that closes the opening on the side of the main body 120. The door 130 is hinged to the main body 120. Thus, the box 100 can be opened or closed by opening and closing the door 130.

[0042] The enclosure 100 has multiple ventilation openings 110. The ventilation openings 110 can be located on the side, top, bottom or other areas of the enclosure 100, and the specific shape of the ventilation openings 110 is not limited. For example, in this embodiment, the ventilation openings 110 are located at the bottom of the door 130, and the ventilation openings 110 are preferably louvered.

[0043] In this embodiment, the protective box 210 is movably disposed above the box door 130, so that the protective box 210 can slide relative to the box door 130 to achieve the purpose of the protective box 210 entering the box body 100 or sliding out of the box body 100.

[0044] During actual installation, the relative position between the protective box 210 and the box door 130 can be adjusted to facilitate adjustment of the outward or inward protrusion of the protective box 210 according to actual needs, increasing adaptability. For example, when it is necessary to reduce the possibility of pedestrians accidentally hitting the protective box 210, the protective box 210 can be fully extended into the box body 100; when it is necessary to appropriately increase the installation space for electronic components inside the box body 100, the protective box 210 can be fully extended out of the box body 100.

[0045] The protective box 210 has an internal hollow structure and multiple ventilation holes 211. Some of the ventilation holes 211 connect the interior of the protective box 210 to the interior of the box body 100, while other ventilation holes 211 connect the interior of the protective box 210 to the exterior of the box body 100, so that the interior of the box body 100 can be connected to the exterior of the box body 100 through the protective box 210.

[0046] The blower 220 is installed inside the protective box 210. The blower 220 is a fan, and the model is not limited. In actual installation, the fan can blow air into the box 100 or out of the box 100, so that the airflow can be controlled by the blower 220 to enter / exit the protective box 210.

[0047] In this embodiment, the fan is selected as a switchable forward and reverse fan, which allows the airflow direction to be switched according to the actual weather conditions. For example, on a sunny day, the airflow direction can be directed towards the inside of the housing 100 to maximize the airflow within the housing 100; on a rainy day, the airflow direction can be directed towards the outside of the housing 100, thereby ensuring a certain airflow while reducing the possibility of external rainwater being blown into the housing 100.

[0048] In actual implementation, the protective box 210 can be configured to include a main body and a lid. The main body has an opening on one side, and the lid is detachably mounted on the main body, covering the opening on the main body. This allows the blower 220 to be easily installed into the protective box 210 by opening and closing the lid. The lid can be connected to the main body by hinges, snap-fits, or other means; there are no restrictions on this.

[0049] When in use, opening the blower 220 can increase the airflow speed inside the protective box 210, thereby effectively increasing the airflow speed between the inside and outside of the box 100. At the same time, with the assistance of the airflow at the vent 110, the circulation effect of the airflow inside and outside the box 100 is improved, effectively increasing the overall heat dissipation effect of the transformer. In addition, during actual installation, the position of the protective box 210 can be adjusted according to actual needs to improve the overall adaptability of the heat dissipation component 200 installation, solving the problem of excessively high overall operating temperature of the transformer due to poor overall heat dissipation effect in the existing technology.

[0050] In other embodiments, the protective box 210 may be placed in other parts of the box body 100. Of course, the protective box 210 may also be rotatably mounted on the box body 100, and there are no restrictions on this.

[0051] like Figure 1 As shown, in some embodiments, the side of the housing 100 is provided with an installation port, and the protective box 210 is slidably disposed in the installation port along the opening direction of the installation port.

[0052] Specifically, the mounting opening is located on the upper part of the door 130, and the size of the mounting opening is adapted to the outer contour of the protective box 210, so that the protective box 210 can be embedded in the mounting opening, and the protective box 210 can slide on the door 130 closer to or further away from the main body 120, so as to adjust the protective box 210 between the inside and outside of the box 100.

[0053] like Figure 2 and Figure 3 As shown, in some embodiments, the housing 100 is provided with a connecting frame 300, and the outer wall of the protective housing 210 is provided with multiple sets of connecting holes 212. Each set of connecting holes 212 is distributed along the sliding direction of the protective housing 210, and the connecting frame 300 is provided with fasteners 310 that cooperate with each connecting hole 212 in the same set.

[0054] In this embodiment, the connecting frame 300 can be detachably fixed to the box door 130 by bolts, screws or other means. The connecting frame 300 has a rectangular frame structure, so that the extension trajectory of the connecting frame 300 is adapted to the outer contour of the protective box 210, so that the connecting frame 300 can be fitted onto the protective box 210.

[0055] At this time, multiple sets of connection holes 212 are provided on the outer wall of the protective box 210. The multiple connection holes 212 are grouped together, and each group of connection holes 212 is distributed along the sliding direction of the protective box 210. The connecting frame 300 is provided with fasteners 310, which can be screws. In this case, the connection holes 212 are internally threaded holes. The fasteners 310 pass through the connecting frame 300 and fit into the connection holes 212, thereby detachably fixing the protective box 210 to the connecting frame 300 through the fasteners 310.

[0056] During actual installation, the fasteners 310 on the connecting frame 300 can be matched with different sets of connecting holes 212 according to actual needs, thereby fixing the protective box 210 in different positions and adjusting the extension of the protective box 210 on the box door 130 to increase adaptability.

[0057] In other embodiments, the protective box 210 can be detachably fixed to the connecting frame 300 by means of buckles, connecting clips or other methods; the fastener 310 can also be a pin.

[0058] In actual implementation, the connecting frame 300 can be configured to include a first frame 320 and a second frame 330. The first frame 320 and the second frame 330 can be integrally formed, or they can be connected by welding or other methods. The second frame 330 is located on the inner edge of the first frame 320. The first frame 320 is connected to the door 130, and fasteners 310 are provided on the second frame 330 to connect the second frame 330 to the protective box 210.

[0059] like Figure 2 As shown, in some embodiments, the connection hole 212 is located on the side of the protective housing 210.

[0060] In actual implementation, the connecting holes 212 are horizontally formed on the outer wall of the protective box 210, and the opposite outer walls of the protective box 210 have multiple connecting holes 212, thereby ensuring the stability of the connecting frame 300 when connected to the protective box 210. In addition, the openings of the connecting holes 212 have a side-opening structure, which reduces the possibility of external rainwater accumulating in the connecting holes 212 when part of the connecting holes 212 are exposed outside the box 100, and reduces the possibility of corrosion of the internal threads of the connecting holes 212.

[0061] like Figure 4 As shown, in some embodiments, a drainage groove 213 is provided on the lower surface of the connection hole 212. One end of the drainage groove 213 extends downward at an angle and connects to the outer surface of the protective box 210.

[0062] It should be noted that the drainage channel 213 is a long, narrow channel located on the lower surface of the connecting hole 212. The drainage channel 213 extends from the bottom of the connecting hole 212 towards its opening, with the end of the drainage channel 213 facing downwards at an angle and connecting to the outer surface of the protective box 210. This design creates an inclined bottom wall for the drainage channel 213. If water enters the connecting hole 212, the drainage channel 213 facilitates the outward flow of water, significantly reducing the possibility of water accumulation within the connecting hole 212.

[0063] like Figure 5 As shown, in some embodiments, the ventilation hole 211 that connects the inside of the protective box 210 to the outside of the box body 100 is located on the side of the protective box 210 away from the inside of the box body 100, and the opening of this ventilation hole 211 at the end away from the box body 100 has an inclined downward structure.

[0064] In this embodiment, a portion of the ventilation holes 211 are located on the side of the protective box 210 facing the interior of the box body 100, and these ventilation holes 211 connect the interior of the protective box 210 with the interior of the box body 100. Another portion of the ventilation holes 211 are located on the side of the protective box 210 away from the interior of the box body 100, and these ventilation holes 211 connect the interior of the protective box 210 with the exterior of the box body 100; in this case, the opening of the portion of the ventilation holes 211 facing away from the box body 100 has an inclined downward structure.

[0065] Therefore, when it rains, external rainwater is less likely to enter the protective box 210 through the ventilation hole 211, thereby reducing the possibility of affecting the electronic components inside the box 100.

[0066] like Figure 5 As shown, the protective box 210 is further provided with a filter 400, which extends into the protective box 210 and is used to filter the airflow flowing inside the protective box 210.

[0067] The plane of the filter screen 400 is perpendicular to the sliding direction of the protective box 210, so that after the filter screen 400 extends into the protective box 210, it can cover the airflow entering and exiting the protective box 210, thereby having a certain filtering effect on the airflow. This further reduces the possibility of external debris entering the box 100 from the protective box 210.

[0068] like Figure 5 As shown, in some embodiments, a socket 214 is provided on one side of the protective box 210, and a connecting strip 410 is provided at one end of the filter screen 400. The end of the filter screen 400 away from the connecting strip 410 is inserted into the protective box 210 from the socket 214, and the connecting strip 410 is detachably connected to the protective box 210.

[0069] Specifically, the connecting strip 410 can be fixed to the filter screen 400 by welding, bonding or other methods. Of course, the two can also be integrally formed, and there is no restriction on this. A socket 214 is provided on one side of the protective box 210. The socket 214 penetrates the box wall of the protective box 210, so that the filter screen 400 can be inserted into the protective box 210 through the socket 214.

[0070] During installation, the end of the filter screen 400 furthest from the connecting strip 410 can be inserted into the protective box 210 through the inlet 214, so that the connecting strip 410 abuts against the outer wall of the protective box 210. Subsequently, the connecting strip 410 can be detachably fixed to the protective box 210 by screwing, plugging, or other methods, thereby realizing the detachable installation of the filter screen 400 on the protective box 210, which facilitates the subsequent disassembly and cleaning of the filter screen 400.

[0071] Preferably, the socket 214 is located on the lower surface of the protective box 210. This reduces the possibility of rainwater entering the protective box 210 through the socket 214.

[0072] like Figure 5 As shown, in some embodiments, the heat dissipation assembly 200 further includes a temperature sensor electrically connected to the blower 220. The temperature sensor is disposed inside the housing 100 and is used to detect the temperature inside the housing 100. When the temperature reaches a preset value, the blower 220 is controlled to operate.

[0073] The temperature sensor can be an existing device, and it is installed inside the enclosure 100, with no restrictions on its specific installation location. This allows the temperature sensor to detect the temperature inside the enclosure 100. When the temperature reaches a preset value, the blower 220 is activated. The type of temperature sensor is not limited, and no other restrictions are imposed, thereby improving overall automation and enhancing the user experience.

[0074] It can also be further configured to control the blower 220 to stop operating when the temperature sensor detects that the temperature inside the chamber 100 has dropped to a preset value.

[0075] In summary, this application provides a prefabricated transformer structure. When in use, opening the blower 220 increases the airflow speed within the protective box 210, thereby effectively increasing the airflow speed between the inside and outside of the box 100. Simultaneously, with the assistance of airflow at the vent 110, the circulation effect of airflow inside and outside the box 100 is improved, effectively increasing the overall heat dissipation of the prefabricated transformer. Furthermore, during actual installation, the position of the protective box 210 can be adjusted according to actual needs, improving the overall adaptability of the heat dissipation components 200. This solves the problem in the prior art where the overall operating temperature of the prefabricated transformer is too high due to poor overall heat dissipation.
