Description

Technical Field

[0001] This utility model relates to the field of prefabricated substation technology, specifically a prefabricated prefabricated substation heat dissipation device. 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 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, fully enclosed, and movable steel structure box. It is particularly suitable for urban power grid construction and renovation, and represents a new type of substation that has emerged after traditional civil engineering substations.

[0003] Prefabricated box-type substations are widely used due to their compact structure and convenient installation. However, heat can easily accumulate in the enclosed space, leading to excessive temperature rise of equipment, which affects its lifespan and operational safety. Most existing box-type substations directly guide outside air into the substation for cooling. Although this can achieve cooling, the air contains particulate dust, and if it is rainy, the guided air will be humid, which can cause damage to the electrical components inside the box-type substation, thus affecting the applicability of the box-type substation.

[0004] Therefore, we propose a prefabricated box-type substation heat dissipation device to solve the above problems. Utility Model Content

[0005] (a) Technical problems to be solved

[0006] To address the shortcomings of existing technologies, this utility model provides a prefabricated box-type substation heat dissipation device, which solves the problem mentioned in the background art that most existing box-type substations directly guide outside air into the box-type substation for cooling, but the air contains particulate dust and is relatively humid on rainy days, which causes damage to electrical components inside the box-type substation.

[0007] (II) Technical Solution

[0008] To achieve the above objectives, this utility model specifically adopts the following technical solution:

[0009] A prefabricated box-type substation heat dissipation device includes a door panel rotatably connected to one side of the box-type substation body, and further includes:

[0010] The channel components are symmetrically arranged on the left and right sides of the box-type substation body. A guide compartment is fixed on the outside of the box-type substation body, and a filter screen is installed at the lower end of the guide compartment.

[0011] The filtration and drying mechanism, located inside the channel component, is used to dry the gas entering the box-type substation.

[0012] The unblocking port is fixed at the upper end of the channel component, and the unblocking port is connected to the guide chamber through the channel component.

[0013] Furthermore, the outer side of the guide chamber is inclined, and the interior of the guide chamber is symmetrically equipped with fan components.

[0014] Furthermore, the filtration and drying mechanism includes a positioning chute, a support plate, and a drying mesh plate. The positioning chute is located inside the box-type substation body and is connected to the channel component. The support plate is fixed to the inner wall of the positioning chute, and the drying mesh plate is evenly fixed inside the support plate.

[0015] Furthermore, the positioning groove is arranged in a stepped shape, and the drying mesh plate is evenly arranged along the inside of the support plate.

[0016] Furthermore, an exhaust port is provided at the lower rear end of the box-type substation body, and the exhaust port has a built-in filter.

[0017] Furthermore, a semiconductor cooling component is fixed to the lower inner end face of the channel component.

[0018] (III) Beneficial Effects

[0019] Compared with the prior art, this utility model provides a pre-installed box-type substation heat dissipation device, which has the following beneficial effects:

[0020] This invention, by incorporating a channel component, a guide chamber, and a fan component, accelerates airflow between the inside and outside of the prefabricated substation, improving heat dissipation efficiency. The guide chamber is angled to facilitate the introduction of external air, while the fan component provides power for airflow. Simultaneously, the drying screen and filter-drying mechanism filter and dry the gas entering the prefabricated substation, reducing the impact of dust and moisture on the equipment. The filter screen initially removes larger particulate impurities from the gas, while the drying screen absorbs moisture. The stepped positioning grooves facilitate the installation and fixation of the support plate and improve the contact efficiency between the gas and the drying screen. Finally, a semiconductor cooling component cools the gas entering the channel component, further enhancing heat dissipation and lowering the temperature of the air entering the prefabricated substation, thus improving heat dissipation performance.

[0027] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0028] Example

[0029] like Figure 1-5 As shown in the figure, an embodiment of the present invention provides a prefabricated box-type substation heat dissipation device, including a door panel 2 rotatably connected to one side of the box-type substation body 1. The door panel 2 facilitates the inspection and maintenance of the equipment inside the box-type substation body 1. The device also includes:

[0030] Channel components 3 are symmetrically arranged on the left and right sides of the box-type substation body 1. Channel components 3 provide a channel for air to enter the interior of the box-type substation body 1. A guide chamber 4 is fixed on the outside of the box-type substation body 1. A filter screen 5 is installed at the lower end of the guide chamber 4. Since the filter screen 5 can perform preliminary filtration on the air entering the guide chamber 4, it can block larger dust particles and debris from entering and causing damage to the fan components 6.

[0031] The outer side of the guide chamber 4 is inclined, and the fan components 6 are symmetrically arranged inside the guide chamber 4. The inclined structure of the guide chamber 4 can more effectively collect and guide the outside air in. Then, when the fan components 6 are working, they can draw the outside air into the guide chamber 4 to provide power for air flow.

[0032] The unblocking port 10 is fixed at the upper end of the channel component 3 and is connected to the guide chamber 4 through the channel component 3. The filtered and dried air enters the interior of the box-type substation body 1 through the unblocking port 10 to dissipate heat from the equipment. The port of the unblocking port 10 can correspond to the electrical equipment, thereby accelerating the heat dissipation effect.

[0033] The filtration and drying mechanism is located inside the channel component 3 and is used to dry the gas entering the box-type substation body 1. The positioning chute 7 is arranged in a stepped shape, and the drying mesh plate 9 is evenly arranged along the inside of the support plate 8. The filtration and drying mechanism includes the positioning chute 7, the support plate 8, and the drying mesh plate 9. The positioning chute 7 is opened on the inside of the box-type substation body 1 and is connected to the channel component 3. The support plate 8 is fixed to the inner wall of the positioning chute 7, and the drying mesh plate 9 is evenly fixed inside the support plate 8. A desiccant can be placed inside the drying mesh plate 9 to dry the passing air. The stepped positioning chute 7 can make the support plate 8 more stable and increase the contact area and time between the air and the drying mesh plate 9, thereby improving the drying effect.

[0034] An exhaust port 11 is provided at the lower rear end of the box-type substation body 1, and the exhaust port 11 has a built-in filter screen. Hot air inside the box-type substation body 1 is discharged through the exhaust port 11 to achieve air circulation. The built-in filter screen can prevent external dust from entering. A semiconductor cooling component 12 is fixed on the lower inner end face of the channel component 3. When the semiconductor cooling component 12 is working, it can reduce the temperature of the air inside the channel component 3, so that the temperature of the air entering the box-type substation body 1 is lower, thereby enhancing the heat dissipation effect. One side of the semiconductor cooling component 12 can cool, and the other side can conduct heat. The heat-conducting side leaks out from the bottom of the box-type substation body 1, thereby ensuring its subsequent heat dissipation effect.

[0035] When the prefabricated substation is in operation, the fan 6 starts, drawing outside air into the guide chamber 4. The air first undergoes preliminary filtration through the filter screen 5 to remove larger impurities. Then, the air enters the channel component 3, where the semiconductor cooling component 12 cools the air. Next, the air flows through the filter drying mechanism, where the drying screen 9 dries the air to remove moisture. The treated cold air enters the interior of the prefabricated substation body 1 through the vent port 10, where it exchanges heat with the equipment. The hot air, having absorbed heat, is discharged outside the box through the exhaust port 11, completing the heat dissipation cycle.

[0036] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
