Description

Technical Field

[0001] This utility model relates to the field of prefabricated substation manufacturing, and in particular to a prefabricated substation with high ventilation. Background Technology

[0002] Prefabricated substations are modular substations that integrate high and low voltage equipment, transformers, switchgear, and other electrical components. They offer advantages such as small size, light weight, easy installation, and reliable operation, and are widely used in urban power grids, industrial parks, and residential communities. However, with the continuous growth of electricity demand and the increasing load on the power grid, the heat dissipation problem of prefabricated substations is becoming increasingly prominent. Traditional heat dissipation methods, such as natural convection or forced air cooling, often suffer from low heat dissipation efficiency, high energy consumption, and difficult maintenance. Natural convection cooling relies on only a few ventilation grilles, resulting in fewer ventilation holes throughout the enclosure and slightly lower heat dissipation performance. Utility Model Content

[0003] The purpose of this invention is to provide a prefabricated substation with good heat dissipation performance and high ventilation.

[0004] The purpose of this utility model is achieved as follows: a prefabricated substation with high ventilation, including a main box body, a top plate, a bottom plate, and side plates;

[0005] The main enclosure consists of a low-pressure chamber and a high-pressure chamber. The high-pressure chamber has a ventilation base plate at its bottom. The ventilation base plate consists of a fixed frame and a base plate. The fixed frame consists of an outer frame and an inner frame. The base plate is placed on the inner frame. The outer frame has a fixed step. The fixed step has a side plate and a movable door. An inclined slope is provided between the fixed step and the top of the outer frame. The base plate has multiple sets of ventilation holes. The movable door and the lower part of the side plate have ventilation grilles, and the upper part has extended ventilation grilles.

[0006] An eaves are provided above the top plate, extending to the outside of the main box. A ventilation plate is provided between the outer edge of the eaves and the main box, and multiple sets of ventilation holes are provided on the top plate.

[0007] Preferably, the extended ventilation grille is composed of an outer shell and a fixing plate. The fixing plate is placed inside the outer shell and has fan mounting holes. The outer shell is connected to the main housing by bolts. Multiple sets of L-shaped baffles are provided at the outer opening of the outer shell, and grilles are provided on the outer side of the L-shaped baffles.

[0008] Preferably, the L-shaped baffle has a rolled edge at the top, and each group of L-shaped baffles is arranged alternately in top and bottom.

[0009] Preferably, a rain guard is provided above the ventilation grille.

[0010] Preferably, the outer frame side is provided with frame ventilation holes that are connected to ventilation holes on the bottom plate.

[0011] Compared with the prior art, the advantages of this utility model are:

[0012] 1. A multi-layered, three-dimensional ventilation channel is formed through the ventilation holes on the bottom plate, the ventilation grilles on the side plates and the lower part of the movable door, and the ventilation holes on the top plate. This design can more effectively remove the heat generated in the high-pressure chamber, significantly reduce the operating temperature of the equipment, and improve heat dissipation efficiency.

[0013] 2. The extended ventilation grille not only increases the ventilation area, but its internal fan mounting holes also allow for the installation of fans for forced ventilation, further improving the heat dissipation effect; at the same time, the L-shaped baffle and grille design prevent foreign objects and rainwater from entering, ensuring smooth ventilation.

[0014] 3. The rain shelters and eaves effectively prevent rainwater from corroding the internal equipment of the substation, ensuring the normal operation of the substation under severe weather conditions. Attached Figure Description

[0025] like Figure 1-6 As shown, a prefabricated substation with high ventilation includes a main enclosure 1, a top plate 2, a base 3, and side plates 4.

[0026] The main housing 1 consists of a low-pressure chamber 101 and a high-pressure chamber 102. The bottom of the high-pressure chamber 102 is provided with a ventilation base plate 5. The ventilation base plate 5 is composed of a fixed frame 501 and a base plate 502. The fixed frame 501 is composed of an outer frame 5011 and an inner frame 5012. The base plate 502 is placed on the inner frame 5012. The outer frame 5011 is provided with a fixed step 50111. The fixed step 50111 is provided with a side plate 4 and a movable door 6. An inclined slope 50112 is provided between the fixed step 50111 and the top of the outer frame 5011. The inclined slope can be used to guide the rainwater that seeps in through the gap of the movable door to drain out, preventing it from seeping into the interior of the housing. The base plate 502 is provided with multiple sets of base plate ventilation holes 5021. The lower part of the movable door 6 and the side plate 4 are provided with ventilation grilles 7, and the upper part is provided with extended ventilation grilles 8.

[0027] like Figure 1 , 3 As shown in Figures 4 and 5, an eaves 9 is provided above the top plate 2, and the eaves 9 extends to the outside of the main box 1. A ventilation plate 10 is provided between the outer edge of the eaves 9 and the main box 1. Multiple sets of top plate ventilation holes 201 are opened on the top plate 2. The ventilation plate and the top plate ventilation holes are connected to improve heat dissipation performance.

[0028] like Figure 5-6 As shown, the extended ventilation grille 8 consists of an outer shell 801 and a fixing plate 802. The fixing plate 802 is placed inside the outer shell 801 and has a fan mounting hole 8021. The outer shell 801 is connected to the main housing 1 by bolts. Multiple sets of L-shaped baffles 803 are provided at the outer opening of the outer shell 801. Grilles 804 are provided on the outer side of the L-shaped baffles 803. The L-shaped baffles can effectively prevent external rainwater from entering.

[0029] like Figure 5-6 As shown, the L-shaped baffle 803 has a rolled edge 8031 ​​on the top, and each group of L-shaped baffles 803 is arranged in an alternating manner; it realizes the dual functions of ventilation and protection, and improves the reliability and safety of the substation.

[0030] like Figure 1 As shown, a rain guard (not shown in the figure) is provided above the ventilation grille 7 to prevent rainwater from dripping directly into the substation, protect the equipment from rainwater erosion, and improve waterproof performance.

[0031] like Figure 2 As shown, the outer frame 5011 has a frame ventilation hole 50113 on its side, which is connected to the ventilation hole 5021 on the bottom plate. When the fan is running, the bottom plate ventilation hole can be connected with the frame ventilation hole, which can ensure that the equipment operates under good heat dissipation conditions.

[0032] The working principle of this utility model is explained as follows: the ventilation holes on the ventilation base plate allow air to circulate freely, carrying away the heat generated by the equipment; at the same time, the ventilation design on the side plates, movable doors, and extended ventilation grilles further enhances the ventilation effect; when external air enters the substation through the ventilation holes, it is heated and rises, and then discharged through the ventilation holes on the top plate; in addition, the fan (if installed) in the extended ventilation grille can accelerate airflow and improve heat dissipation efficiency.
