Description

Technical Field

[0001] This application relates to the field of power equipment heat dissipation technology, and in particular to a European-style transformer substation chimney-type heat dissipation top cover. Background Technology

[0002] In modern power systems, European-style prefabricated substations, with their advantages of high integration, small footprint, and convenient installation, have become core equipment for urban power distribution networks, industrial and mining enterprises, and residential communities. Internally, they integrate key electrical components such as high-voltage switchgear, transformers, and low-voltage distribution devices. During operation, they continuously generate a large amount of heat due to energy conversion and line losses. If the heat dissipation system is poorly designed or environmental ventilation is limited, heat will accumulate continuously in the enclosed space, causing a significant increase in internal temperature.

[0003] European-style transformer substation heat dissipation covers are typically made of high-strength aluminum alloy or stainless steel, combining lightweight, corrosion resistance, and high mechanical strength. Their main structure consists of a frame, heat sinks, vents, and a protective mesh. The frame provides a stable support structure for the cover. The heat sinks, in the form of fins, are distributed over a large area on the surface or inside of the cover, increasing heat dissipation efficiency by increasing the surface area. The vents are arranged in an array to create channels for airflow, and the protective mesh covers the vents to prevent foreign objects from entering the transformer substation. The working principle is based on heat exchange theory. Heat generated inside the transformer substation is transferred to the cover and heat sinks through heat conduction. When outside air flows through the vents, the cool air comes into contact with the hot heat sinks, using the principle of thermal convection to remove heat. Simultaneously, the forced convection generated by natural wind further accelerates airflow, enhancing the heat dissipation effect and thus maintaining the electrical components inside the transformer substation within a reasonable operating temperature range.

[0004] Some current European-style transformer substation heat dissipation covers have significant defects in actual use. On the one hand, traditional heat dissipation covers rely on natural convection or a single fan for heat dissipation when the transformer substation is under high load. The air circulation speed is slow and it is difficult to quickly dissipate a large amount of heat, causing the internal temperature of the equipment to rise continuously, which seriously affects the stability and service life of electrical components. On the other hand, expanding the ventilation openings to enhance heat dissipation can easily cause rainwater to backflow. If a closed design is adopted to ensure waterproofing, the heat dissipation effect will be greatly weakened, resulting in the inability to meet the requirements of heat dissipation and waterproofing at the same time. Therefore, a European-style transformer substation chimney-type heat dissipation cover is proposed to solve the above problems. Utility Model Content

[0005] The purpose of this application is to provide a chimney-type heat dissipation top cover for European-style prefabricated substations, which aims to improve the problems of insufficient heat dissipation efficiency and difficulty in balancing heat dissipation and waterproofing functions in existing European-style prefabricated substations during high-load operation.

[0006] The technical solution for the European-style transformer substation chimney-type heat dissipation top cover provided in this application is as follows:

[0007] A European-style transformer substation chimney-type heat dissipation top cover includes a top cover body, and a ventilation mechanism is provided at the top of the top cover body;

[0008] The ventilation mechanism includes two fixed frames, the bottom ends of which are fixedly connected to the top of the main body of the top cover. A waterproof cover plate is fixedly connected to the top of each fixed frame. A ventilation fan is fixedly connected inside the fixed frame. A ventilation opening is provided between the fixed frame and the waterproof cover plate. A reinforcing component is provided at the bottom of the main body of the top cover.

[0009] As a further description of the above technical solution, the ventilation fan and the chimney-type ventilation structure work together to accelerate air convection. Compared with traditional heat dissipation methods, the heat dissipation efficiency is significantly improved, which can meet the heat dissipation requirements of the transformer substation when operating under high load. At the same time, the waterproof cover can effectively prevent rainwater from entering the interior of the transformer substation.

[0010] Preferably, the reinforcing component includes multiple vertical fixing plates, the external of which are fixedly connected to the bottom end of the top cover body, multiple horizontal fixing plates are fixedly connected to the adjacent side of two vertical fixing plates, and a support frame is fixedly connected to the bottom end of the top cover body.

[0011] As a further description of the above technical solution, the horizontal and vertical fixing plates cooperate with the support frame to enhance the structural strength of the main body of the top cover. Even in severe weather conditions such as strong winds and heavy rain, the stability of the top cover can be guaranteed, and the heat dissipation and waterproof functions can be avoided due to structural damage.

[0012] Preferably, the outer surfaces of the plurality of horizontal fixing plates are arranged in an array on adjacent sides of the two vertical fixing plates;

[0013] As a further description of the above technical solution, the distribution of multiple horizontal fixed plates in an array improves the overall stability of the device.

[0014] Preferably, the top of the main body of the top cover is slanted to facilitate the flow of rainwater, thus combining heat dissipation and waterproofing functions.

[0015] As a further description of the above technical solution, the sloping top cover design allows rainwater to slide off quickly under the action of gravity, preventing rainwater from accumulating on the top cover surface and seeping into the box. Combined with the waterproof cover plate, it achieves double waterproof protection and ensures the safety of the equipment inside the transformer.

[0016] Preferably, the two fixing frames are arranged in an array at the top of the top cover body.

[0017] As a further description of the above technical solution, the positioning of the mounting bracket improves the ventilation effect.

[0018] Preferably, the fixing frame and the waterproof cover plate form a chimney-type ventilation structure.

[0019] As a further description of the above technical solution, the chimney-type ventilation structure utilizes the chimney effect to accelerate the exhaust of hot air and guide the replenishment of external cold air with the assistance of a ventilation fan, forming an efficient air circulation and significantly improving the heat dissipation effect.

[0020] In summary, this application includes at least one of the following beneficial technical effects:

[0021] 1. This utility model effectively solves the heat dissipation and waterproofing problems of European-style box-type substations. In terms of heat dissipation, the ventilation mechanism at the top of the cover adopts a combination of a chimney-type structure and a ventilation fan. When the box-type substation generates heat during operation, the fan drives the air to flow upward through the ventilation opening, using the chimney effect to accelerate the discharge of hot air, while simultaneously promoting the continuous replenishment of external cold air, forming efficient convection. Compared with traditional heat dissipation methods, this significantly improves the airflow speed and flow rate, meeting the heat dissipation requirements of the box-type substation operating under high load. In terms of waterproofing, the waterproof cover plate directly covers the ventilation opening, which can effectively prevent rainwater from entering the interior of the box-type substation. The sloping top cover body allows rainwater to slide off quickly, preventing water from seeping in. In addition, the reinforcement components enhance the structural strength of the top cover through horizontal and vertical fixing plates and support frames, ensuring the stability of the top cover under severe weather conditions, making the waterproofing and heat dissipation functions continuously reliable, and ensuring the stable operation of the box-type substation in complex environments.

[0028] The following is in conjunction with the appendix Figure 1 - Appendix Figure 4 This application will be described in further detail below.

[0029] Example: A European-style transformer substation chimney-type heat dissipation top cover, refer to Figures 1 to 3 The system includes a top cover body 1, which is made of high-strength, corrosion-resistant metal with a special coating that effectively resists corrosion from complex outdoor environments and provides a stable mounting base for internal components. A ventilation mechanism 2 is located at the top of the top cover body 1. This mechanism is specifically designed to address heat dissipation during operation, achieving efficient cooling through an innovative structure. The ventilation mechanism 2 includes two mounting brackets 21, whose bottom ends are fixedly connected to the top of the top cover body 1 with high-strength bolts, ensuring a secure connection and providing reliable support for subsequent component installation. Each mounting bracket 21 has a waterproof cover plate 22 fixedly connected to its top for waterproofing. The cover plate 22 adopts a streamlined design, which can not only effectively block rainwater, but also reduce wind resistance. The internal fixed connection of the fixing frame 21 is a ventilation fan 23. The ventilation fan 23 is a high-speed, low-noise model that can generate strong wind and accelerate air flow during operation. A ventilation opening 24 is provided between the fixing frame 21 and the waterproof cover plate 22. The size of the ventilation opening 24 has been precisely calculated to ensure smooth air flow and prevent foreign objects from entering. A reinforcing component 25 is provided at the bottom of the top cover body 1. The reinforcing component 25 is used to enhance the overall structural strength of the top cover and ensure stable operation in severe weather. The two fixing frames 21 are arranged in an array at the top of the top cover body 1.

[0030] Specifically, when the transformer substation generates heat during operation, the ventilation fan 23 is activated, and its high-speed operation generates strong airflow. Driven by the wind, air enters the chimney-like ventilation structure composed of the fixed frame 21 and the waterproof cover 22 through the ventilation opening 24. Due to the chimney effect, the hot air accelerates upward and is discharged, while external cold air continuously replenishes it, forming an efficient air convection circulation. This quickly removes the heat generated by the transformer substation, achieving efficient heat dissipation. At the same time, the streamlined design of the waterproof cover 22 effectively guides rainwater, preventing rainwater from entering the interior of the transformer substation through the ventilation opening 24, thus ensuring both heat dissipation and good waterproofing.

[0031] Reference Figure 1 , Figure 3 and Figure 4The reinforcing component 25 includes multiple vertical fixing plates 252. The external parts of the multiple vertical fixing plates 252 are firmly fixed to the bottom of the main body 1 of the top cover by welding or bolts, forming a vertical support structure to enhance the deformation resistance of the top cover. Multiple horizontal fixing plates 251 are fixedly connected to the adjacent side of two vertical fixing plates 252. The horizontal fixing plates 251 and the vertical fixing plates 252 are interlaced to form a grid-like reinforcing structure, which further improves the stability of the top cover. The bottom of the main body 1 of the top cover is fixedly connected to a support frame 253. The support frame 253 adopts a triangular stable structure design to provide additional support for the entire top cover. The external parts of the multiple horizontal fixing plates 251 are arranged in an array on the adjacent side of two vertical fixing plates 252. The fixing frame 21 and the waterproof cover plate 22 form a chimney-type ventilation structure. This structure utilizes the principle of aerodynamics to naturally guide the airflow. The top of the main body 1 of the top cover is slanted, and its tilt angle is scientifically designed to facilitate the rapid flow of rainwater, so as to take into account both heat dissipation and waterproof functions.

[0032] Specifically, the vertical fixing plate 252 is fixed vertically to the bottom of the main body 1 of the roof, forming a stable vertical support to resist external forces in the vertical direction and enhance the roof's resistance to deformation. The horizontal fixing plate 251 is staggered with the vertical fixing plate 252 to form a grid-like reinforcement system, which disperses and bears loads from different directions, further improving the overall stability of the roof. The triangular structure of the support frame 253 utilizes the stability principle of triangles to provide additional support for the roof, ensuring that the main body 1 of the roof will not shake or deform under severe weather conditions such as strong winds and heavy rain, ensuring the continuous and stable operation of the ventilation mechanism 2 and the waterproof structure, so that the heat dissipation and waterproof functions are not affected.

[0033] Working principle: In terms of heat dissipation, the ventilation mechanism 2 set at the top of the main body 1 plays a key role. The bottom ends of the two fixed brackets 21 in the ventilation mechanism 2 are connected to the top of the main body 1. The ventilation fan 23 is fixedly connected inside the fixed bracket 21. At the same time, the fixed bracket 21 and the waterproof cover plate 22 form a ventilation opening 24. The two together form a chimney-type ventilation structure. When the transformer generates heat during operation, the ventilation fan 23 is activated. Driven by the fan, the air flows upward from the inside of the transformer through the ventilation opening 24. Utilizing the chimney effect, the hot air is accelerated to be discharged. External cold air is continuously replenished into the inside of the transformer, forming air convection. Compared with traditional heat dissipation methods, the combination of the chimney-type structure and the ventilation fan 23 significantly enhances the air flow speed and flow rate, thereby greatly improving the heat dissipation efficiency and meeting the heat dissipation requirements of the transformer during high-load operation.

[0034] In terms of waterproofing, on the one hand, the waterproof cover plate 22 is installed on the top of the fixing frame 21 of the ventilation mechanism 2, which can directly block rainwater from falling and prevent rainwater from entering the transformer through the ventilation opening 24; on the other hand, the top of the top cover body 1 is designed to be inclined. When rainwater falls on the top cover body 1, it will slide down quickly along the inclined surface under the action of gravity, further preventing rainwater from accumulating on the surface of the top cover and seeping into the transformer. The vertical fixing plate 252, horizontal fixing plate 251 and support frame 253 in the reinforcement component 25 enhance the structural strength of the top cover body 1, ensure the stability of the entire heat dissipation top cover under severe weather conditions, and ensure that the waterproof and heat dissipation functions are not affected.
