Description

Technical Field

[0001] The present application relates to the technical field of European-style substations, and in particular to a European-style substation. Background Art

[0002] The European-style substation was the first power transformation technology introduced to China from Europe. It is also called the YBW-12 series prefabricated substation. The YBW-12 series prefabricated substation combines high-voltage electrical equipment, transformers, low-voltage electrical equipment, etc. into a compact complete distribution device. The box material is made of channel steel, aluminum alloy and flame-retardant composite materials.

[0003] In the related art, European-style substations that can be spliced and assembled will generate a lot of noise during use, and many European-style substations are installed in cities, such as residential areas, and the noise they generate can easily affect the daily lives of surrounding residents. Summary of the Invention

[0004] In order to reduce the noise during operation of a European-style substation, the present application provides a European-style substation.

[0005] The European-style substation provided in this application adopts the following technical solutions: A European-style substation comprises a bottom module mechanism, a side module mechanism and a top module mechanism which are sequentially connected; The bottom module structure includes a square middle block, edge blocks, and corner blocks that are assembled and spliced together to form the bottom surface. The bottom surface is provided with a plurality of support frames arranged along the outer wall. The plurality of support frames are provided with a plurality of mounting slots, and the plurality of support frames are provided with a plurality of ventilation holes. The support frames are provided with sound-absorbing sponge strips that fit the ventilation holes. The side module mechanism includes a plurality of side panels, each of which extends into and is inserted into corresponding mounting slots. After installation, the plurality of side panels form two continuous inner and outer side walls, the outer side wall cover is arranged on the inner side wall, and the inner side wall is sleeved on the bottom surface; The top surface module mechanism includes several outer top plates connected to the outer side wall and several inner top plates connected to the inner side wall. The several inner top plates cooperate with the inner side wall to form an inner top surface. A servo motor is provided on the inner top surface. A supporting top plate is provided on the rotating shaft of the servo motor. The outer top plate and the supporting top plate are connected to form the outer top surface, and the fan blades are fixedly connected to the rotating shaft.

[0006] By adopting this technical solution and assembling standardized panels (center, edge, and corner panels), the construction period is shortened and costs are reduced. Rubber strips between panels provide shock absorption, while sound-absorbing sponge strips absorb noise. Combined with the spiral airflow created by the air guide structure, this suppresses noise transmission. A servo motor drives the fan blades, creating air flow, and hot air is discharged through the side panel vents, improving heat dissipation efficiency within the substation.

[0007] Optionally, the bottom module mechanism further includes connecting plates for connecting the modules, and the connecting plates extend into adjacent blocks respectively.

[0008] By adopting the above technical solution, the connecting plate fixes the blocks with bolts to prevent loosening and improve the overall structural rigidity. The connecting plate abuts against the rubber strip to further absorb vibration between the blocks and reduce noise sources.

[0011] Optionally, the side module mechanism further includes an air guide vertical plate arranged between the inner side wall and the outer side wall, and the air guide vertical plate extends into the support frame.

[0012] By adopting this technical solution, the vertical air guide plate guides the spiral airflow at the top to the ventilation holes at the bottom, forming a circulating air duct and improving heat dissipation efficiency. The vertical plate cooperates with the support frame to block the outward transmission path of noise and reduce external noise interference.

[0013] Optionally, the side panel located on the outer side wall is provided with an outer door that rotates outward to open, and the side panel located on the inner side wall is provided with an inner door that opens outward, and the positions of the inner door and the outer door correspond.

[0014] By adopting this technical solution, the double doors provide independent access and exit channels, facilitating simultaneous maintenance of equipment on the inner and outer walls. When closed, the double doors form a labyrinth seal, reducing air leakage and dust intrusion.

[0015] Optionally, the servo motor upper cover is provided with an arc-shaped cover located below the fan blades, the arc-shaped cover smoothly transitions to the inner top surface, the outer top surface is provided with a plurality of air inlets, and dust screens are provided in the air inlets.

[0016] By adopting this technical solution, the curved hood isolates the fan blades from the external environment, preventing foreign matter from entering and reducing maintenance frequency. The dust screen filters incoming dust, preventing internal dust accumulation that affects heat dissipation efficiency; the curved hood smooths airflow and reduces turbulent noise.

[0017] Optionally, the side module mechanism also includes a number of wind guide horizontal plates arranged between the inner top surface and the outer top surface, the number of wind guide horizontal plates are arranged along the circumference of the arc cover, one end of the number of wind guide horizontal plates is connected to the arc cover, and the other end of the number of wind guide horizontal plates extends between the inner and outer continuous side walls.

[0018] By adopting this technical solution, the horizontal air guide plate guides the spiral airflow from the top to the side wall vents, forming a continuous air duct and improving heat dissipation uniformity. The horizontal air guide plate is fixed to the fan-shaped strips and curved plates to help support the top module and prevent deformation.

[0019] Optionally, the top surface module mechanism also includes a number of inner top frames arranged on the upper end surface of the inner wall and a number of outer top frames arranged on the upper end surface of the outer wall. The positions of the several inner top frames and the outer top frames are arranged correspondingly. A fixing plate is provided on one side of the several inner top frames close to the outer wall, and the fixing plate extends toward the outer wall and is connected to the outer wall.

[0020] By adopting this technical solution, the inner and outer top frames form a double-layer frame, distributing the top load and improving the compressive strength. The fixed plate connects the inner and outer top frames, stabilizing the position of the wind guide plate and ensuring a stable airflow path.

[0021] In summary, this application includes at least one of the following beneficial technical effects: 1. Rapid assembly is achieved through standardized blocks, adapting to different scene requirements and reducing construction difficulty; 2.
