[0002] Ring main units are a type of equipment used in power transmission and distribution networks. They are widely used in substations and prefabricated substations in load centers such as residential communities, large public buildings, and factories, and many are also installed outdoors.

[0003] Ring main units generate a lot of heat during operation, so matching heat dissipation holes need to be designed. However, in the current outer casing structure of ring main units, most only a few strip openings are opened at the bottom or top of the side wall to achieve a simple ventilation and heat dissipation effect. However, the opening position of the holes is not good, and the airflow path is not restricted in any way. Even if there is external wind, it cannot be well utilized. There is still room for improvement in heat dissipation performance. Utility Model Content

[0016] The technical solution of this utility model will be further described below with reference to the accompanying drawings and specific embodiments.

[0017] like Figures 1 to 4 As shown in the figure, a specific embodiment of the present invention discloses an outer casing structure for a ring main unit, including a casing 100. One wall of the casing has an open opening, and a door is installed at the open opening. Each wall of the casing 100 has a vertically extending strip opening 110, which is located on the same side of the corresponding wall, so that the four strip openings are distributed near the four corners of the casing. An air guide 200 is installed at the strip opening 110, and the air outlet of the air guide extends into the interior of the casing and bends towards the center of the casing, so that the airflow moves towards the edge near the center of the casing. The top of the casing 100 has an exhaust hole 120 for external exhaust. The aforementioned ring main unit enclosure structure, by incorporating air guides, can limit the direction of airflow, allowing it to flow along the inner wall of the enclosure and pass through the outer perimeter of the internal unit, thus better removing heat and improving heat dissipation performance. Furthermore, during active exhaust, airflow from different directions will not interfere with each other, accelerating airflow speed and further enhancing heat dissipation. Even on walls with enclosure doors, air guides are installed, ensuring unimpeded door installation and opening / closing, while also guiding airflow from that wall direction, effectively directing and utilizing external airflow. It should be noted that enclosure doors are common structural components, and their installation methods are relatively conventional, so details will not be elaborated upon.

[0018] Furthermore, such as Figure 5 , Figure 6 As shown, the air guide 200 includes a frame strip 210, with a pressure strip 220 fixedly provided on one outer wall of the frame strip 210, and the other side bent. The frame strip 210 is snapped into the slot 110, and the pressure strip 220 abuts against the outer wall of the housing 100 and is fixedly connected by bolts. The bent side extends into the interior of the housing and bends towards the center of the housing. The frame strip 210 is provided with a channel 230 extending along the length direction. The channel runs through both sides of the frame strip along the bending direction, serving as the part through which the gas flows. This further defines the structure of the air guide. The channel is designed along the bending direction, thereby limiting the airflow to move in the direction of the bend. The pressure strip is installed on the housing by bolts, making it a detachable component, which facilitates its processing and production, and also makes assembly convenient. The air guide is snapped into the slot. It should be noted that the end face of the bent part is flush with one side of the slot, ensuring that this part can extend into the interior of the housing through the slot, avoiding installation difficulties due to interference.

[0019] Furthermore, the width of the channel 230 gradually increases from the inner port to the outer port, forming a flared structure at the outer port. The outer port is the wind inlet, which can facilitate the smooth entry of external airflow. It can also strengthen the airflow and expand the heat dissipation range by narrowing the flow passage.

[0020] Furthermore, multiple flow-limiting plates 240 are fixedly installed at the inner port of the channel 230. The flow-limiting plates are evenly spaced along the vertical direction of the frame. The flow-limiting plates are inclined downward towards the inner side of the channel. This design can provide an upward guiding effect for the airflow, which can better carry the heat upward and facilitate its discharge from the exhaust port. On the other hand, it can also block moisture to a certain extent, especially in rainy weather, to prevent rainwater from entering the interior and reduce the amount of moisture entering the interior.

[0021] Furthermore, a flow divider 250 is provided at the inner port of the channel 230. The flow divider is located in the middle and extends vertically to the top and bottom, penetrating the flow limiter and forming a separation between the flow limiter 240. On the one hand, it can strengthen the overall structural strength, and on the other hand, it can limit and reduce the opening, preventing external animals such as snakes and rats from entering without significantly affecting the airflow path.

[0022] Furthermore, such as Figure 2 , Figure 3As shown, a through hole 130 is provided in the middle of the top surface of the box 100. A support tube 140 extending upward is fixed on the outer side of the top of the through hole 130. A baffle 150 is provided on the top of the support tube 140. The baffle 150 extends outward from all sides beyond the outer wall of the support tube 140 to form a shield. An exhaust hole 120 is provided on the outer wall of the support tube 140. The exhaust part is another important point for heat dissipation. Since hot air has the characteristic of rising, it is located at the top of the box. It also matches the collection and discharge of the airflow guided upward by the air guide. Considering rainy weather, an upward-protruding support tube is provided to raise the position of the exhaust hole. With the shielding and covering of the baffle, rainwater is effectively prevented from entering the box through the exhaust hole.

[0023] Furthermore, a sponge pad 160 is provided on the outer bottom of the support tube 150, and the sponge pad 160 is attached and fixed to the top surface of the box 100. The sponge pad 160 extends outwards from all sides, beyond the coverage area of ​​the baffle 150; the sponge pad buffers and absorbs rainwater falling from above, reducing the splashing of rainwater caused by hard impacts, and further preventing rainwater from entering the interior of the box.

[0024] Furthermore, such as Figure 2 , Figure 4 As shown, a support frame 300 is provided below the bottom of the through hole 130. The support frame 300 is bolted to the top inner wall of the housing 100. The bottom of the support frame 300 extends downward and is provided with a bracket 310. There is a gap between the bracket and the top inner wall of the housing, and the support frame is provided with holes for airflow. An exhaust fan 400 is installed on the bracket 310, and the exhaust fan blows air towards the through hole. This structural design enables active exhaust cooling, further coping with different weather conditions and meeting the required cooling needs. It should be noted that a wind direction and speed sensor for monitoring wind direction and speed is also installed on the housing, and a temperature sensor for monitoring the internal temperature is installed inside the housing to match natural airflow cooling or active exhaust cooling according to wind direction, wind speed, and internal temperature. It should be noted that the wind direction and speed sensor and the temperature sensor are common sensors that can be purchased and used on the market, and will not be described in detail.

[0025] Furthermore, such as Figure 2As shown, the box includes a support frame with open top and bottom, a support plate installed at the bottom, and first angle steel at each of the four corners of the top surface of the support plate. The first angle steel is tightly attached to the inner wall of the bottom corner of the box and fixedly connected by bolts. A cover plate is installed on the top of the support frame, and second angle steel at each of the four corners of the bottom surface of the cover plate is tightly attached to the inner wall of the top corner of the box and fixedly connected by bolts, thus forming the box. The box adopts a split structure, which facilitates the processing and production of each structural component and also facilitates assembly. The box includes through holes... The support tube and sponge pad are both located on the cover plate. The baffle is welded and fixed to the top of the support tube, or can be detachably installed on the top of the support tube. Its main function is to block rain and prevent rainwater from drifting horizontally into the box. In addition, the top surface of the cover plate is arched in the middle and slopes downward from the middle to the surrounding area at an angle of 1°-2° to form a downward guide surface, which facilitates the downward flow of rainwater. Furthermore, the sponge pad can reduce the impact effect of falling rainwater and further prevent rainwater from splashing and entering the box through the vent.
