[0052] Unless otherwise specified, the term "plurality" means two or more.

[0053] As can be seen from the background art, various devices installed in the switchgear cabinet generate a large amount of heat during operation. If this heat cannot be effectively dissipated, it may cause the devices to overheat, thereby affecting their performance and lifespan, and affecting the safety and reliability of the power system.

[0054] In the prior art, ventilation openings are added to the switchgear cabinet to improve air circulation, thereby enhancing the heat dissipation effect. However, the actual effect of this method is limited. Especially in the case of dense equipment, the ventilation openings may not provide sufficient heat dissipation.

[0055] To improve the heat dissipation effect, a fan can be installed on the switchgear cabinet to force air flow, thereby improving the heat dissipation efficiency. However, the blowing angle of the fan is difficult to adjust, which may cause uneven heat dissipation inside the switchgear cabinet.

[0056] A liquid cooling system can also be arranged inside the switchgear cabinet to take away the heat generated by the devices through circulating coolant. However, the cost of the liquid cooling system is relatively high, and the system design and maintenance are relatively complex, which is relatively limited in practical applications.

[0057] Accordingly, the embodiment of the present application provides a relay protection room cabinet, including a cabinet body, the cabinet body forming a receiving cavity for accommodating electrical components; the cabinet body is provided with an air inlet and an air outlet, an intake fan is arranged in the cabinet body, the air inlet end of the intake fan is communicated with the outside of the cabinet body, and the air outlet end of the intake fan discharges air into the receiving cavity through the air inlet of the cabinet body; an exhaust fan is arranged in the cabinet body, the air inlet end of the exhaust fan is communicated with the receiving cavity, and the air outlet end of the exhaust fan discharges air to the outside of the cabinet body through the air outlet of the cabinet body; through the intake fan and the exhaust fan, a heat dissipation structure with forced air flow is formed on the cabinet body, promoting the air outside the cabinet body to enter the cabinet body and promoting the hot air inside the cabinet body to be discharged from the cabinet body, improving the air flow rate inside the cabinet body, thereby improving the heat dissipation efficiency, and further effectively improving the heat dissipation effect inside the relay protection room cabinet.

[0058] The technical solution of the present application will be described in detail below with reference to the accompanying drawings and specific embodiments. These specific embodiments may be combined with each other, and the same or similar concepts or processes may not be described again in some embodiments.

[0059] Figure 1 It is a schematic structural diagram of the relay protection room cabinet provided by the embodiment of the present application; Figure 2 is Figure 1 a schematic structural diagram with the intake fan removed; Figure 3 is Figure 1 a schematic structural diagram with the exhaust fan removed.

[0060] As Figures 1 to 3 shown, the embodiment of the present application provides a relay protection room cabinet, including a cabinet body 100, electrical components, an intake fan 200 and an exhaust fan 300; the cabinet body 100 forms a receiving cavity, and the receiving cavity accommodates electrical components; the cabinet body 100 is provided with an air inlet 120 and an air outlet 130, and both the air inlet 120 and the air outlet 130 are communicated with the receiving cavity; the intake fan 200 is arranged in the cabinet body 100, the air inlet end of the intake fan 200 is communicated with the outside of the cabinet body 100, and the air outlet end of the intake fan 200 discharges air into the receiving cavity through the air inlet 120 of the cabinet body 100; the exhaust fan 300 is arranged in the cabinet body 100, the air inlet end of the exhaust fan 300 is communicated with the receiving cavity, and the air outlet end of the exhaust fan 300 discharges air to the outside of the cabinet body 100 through the air outlet 130 of the cabinet body 100.

[0061] It can be understood that the electrical components include electrical equipment, relays, protection devices and their auxiliary equipment in the relay protection system. These devices generate a large amount of heat during operation, especially high-power devices such as relays and protection devices. If these devices cannot be effectively cooled, it will cause the temperature to be too high, resulting in equipment failure or even damage, affecting the safety and reliability of the power system.

[0062] In specific implementation, the operation of the intake fan 200 can force the air flow near the intake fan 200 to introduce the air with relatively lower temperature outside the cabinet body 100 (hereinafter referred to as cold air) into the accommodation cavity of the cabinet body 100, thereby reducing the internal temperature of the cabinet body 100 to achieve heat dissipation for the electrical components.

[0063] However, it is not enough to only introduce the cold air outside the cabinet body 100 through the intake fan 200. It is also necessary to discharge the hot air from the cabinet body 100. By setting the exhaust fan 300, the hot air inside the cabinet body 100 can be discharged to the outside of the cabinet body 100. Thus, it can promote the air flow in the cabinet body 100, improve the heat dissipation effect, ensure the timely dissipation of internal heat, and prevent the equipment from overheating.

[0064] Specifically, by setting the intake fan 200 and the exhaust fan 300 on the cabinet body 100, a heat dissipation structure for forced air flow is formed, which promotes the cold air outside the cabinet body 100 to enter the cabinet body 100 and promotes the hot air inside the cabinet body 100 to be discharged from the cabinet body 100, improving the rate of air flow inside the cabinet body 100, thereby improving the heat dissipation efficiency, further effectively improving the heat dissipation effect inside the relay protection room cubicle, reducing the risk of overheating of electrical components, extending the service life of electrical components, and improving the safety and reliability of the power system.

[0065] It should be noted that the embodiments of the present application do not impose any restrictions on the shapes of the air inlet 120 and the air outlet 130. When the intake fan 200 operates, it can exhaust air into the accommodation cavity through the air inlet 120, and when the exhaust fan 300 operates, it can exhaust air to the outside of the cabinet body 100 through the air outlet 130.

[0066] The sizes of the air inlet 120 and the air outlet 130 can be determined in combination with the parameters of the actually installed intake fan 200 and exhaust fan 300. Exemplarily, the sizes of the air inlet 120 and the air outlet 130 can be slightly larger than the outlet sizes of the fans to avoid air flow restriction and ensure the smoothness of air circulation.

[0067] Exemplarily, a dust-proof net can be provided at the air inlet 120 to reduce the possibility of external dust entering the cubicle through the air inlet 120 and ensure the normal operation of the electrical components installed inside.

[0068] In some embodiments, the cabinet body 100 has a front wall and a rear wall that are oppositely arranged, and two side walls that are oppositely arranged; the air inlet 120 is provided on one of the front wall and the rear wall, and the air outlet 130 is provided on the other of the front wall and the rear wall.

[0069] It should be noted that the side of the outer shell of the cabinet body 100 facing Figure 2 the X direction is the front wall of the cabinet body 100, and the outer shell of the cabinet body 100 faces away from Figure 2One side in the X direction is the rear wall of the cabinet body 100; the outer shell of the cabinet body 100 faces Figure 2 One side in the Y direction is the left side wall of the cabinet body 100, and the outer shell of the cabinet body 100 faces away from Figure 2 One side in the Y direction is the right side wall of the cabinet body 100; the outer shell of the cabinet body 100 faces Figure 2 One side in the Z direction is the top wall of the cabinet body 100, and the outer shell of the cabinet body 100 faces away from Figure 2 One side in the Z direction is the bottom wall of the cabinet body 100.

[0070] Exemplarily, the air inlet 120 can be arranged on the front wall of the cabinet body 100, and the air outlet 130 can be arranged on the rear wall of the cabinet body 100. By arranging the air inlet 120 and the air outlet 130 in the front-rear direction of the cabinet body 100, and the air inlet 120 and the air outlet 130 are located on the opposite sides of the cabinet body 100, an air flow path along the front-rear direction of the cabinet body 100 can be formed for the air inlet 120, the accommodation cavity and the air outlet 130. The cold air enters the cabinet body 100 through the air inlet 120, can effectively pass through the whole cabinet body 100, thereby taking away more heat, and the formed hot air is then discharged from the cabinet body 100 through the air outlet 130, improving the heat dissipation efficiency.

[0071] In some other embodiments, the air inlet 120 is arranged on one of the two side walls, and the air outlet 130 is arranged on the other of the two side walls.

[0072] Exemplarily, the air inlet 120 can be arranged on the left side wall of the cabinet body 100, and the air outlet 130 can be arranged on the right side wall of the cabinet body 100. By arranging the air inlet 120 and the air outlet 130 in the left-right direction of the cabinet body 100, and the air inlet 120 and the air outlet 130 are located on the opposite sides of the cabinet body 100, an air flow path along the left-right direction of the cabinet body 100 can be formed for the air inlet 120, the accommodation cavity and the air outlet 130. The cold air enters the cabinet body 100 through the air inlet 120, can effectively pass through the whole cabinet body 100, thereby taking away more heat, and the formed hot air is then discharged from the cabinet body 100 through the air outlet 130, improving the heat dissipation efficiency.

[0073] It can be understood that the layout positions of the air inlet 120 and the air outlet 130 can be adaptively selected according to the actual installation environment and heat dissipation requirements of the relay protection indoor switchgear. For example, when the front-rear space of the cabinet body 100 is limited, the air inlet 120 and the air outlet 130 can be arranged in the left-right direction of the cabinet body 100; when the left and right sides of the cabinet body 100 are limited in space, the air inlet 120 and the air outlet 130 can be arranged in the front-rear direction of the cabinet body 100.

[0074] In some embodiments, an opening is provided on the front wall of the cabinet body 100, and the opening communicates with the accommodation cavity; a movable door body 110 is provided on the front wall, and the door body 110 closes or opens the opening; an air inlet 120 is provided on the door body 110, and the air inlet fan 200 is fixedly connected to the door body 110; an air outlet 130 is provided on the rear wall of the cabinet body 100, and the air outlet fan 300 is fixedly connected to the rear wall of the cabinet body 100.

[0075] It can be understood that the opening on the front wall provides a convenient access and operation channel, enabling maintenance personnel to easily access and operate the internal electrical components.

[0076] In practical applications, the electrical components installed in the cabinet need to be regularly maintained and inspected. For the convenience of maintenance, a door body 110 is usually provided on the rear wall of the cabinet body 100, so that maintenance personnel can easily enter the interior of the cabinet body 100 to perform necessary operations and maintenance work, reducing the maintenance difficulty and time, and improving the maintenance efficiency and operation convenience.

[0077] Among them, the air inlet 120 can be provided on the door body 110 located on the front wall of the cabinet body 100; the air outlet 130 can be provided on the door body 110 located on the rear wall of the cabinet body 100, and the air outlet fan 300 is fixedly connected to the door body 110 located on the rear wall of the cabinet body 100. By arranging both the air inlet fan 200 and the air outlet fan 300 on the door body 110, the space inside the cabinet body 100 can be avoided from being occupied, and the space utilization rate inside the cabinet body 100 can be improved.

[0078] Specifically, in the embodiment of the present application, an opening and a movable door body 110 are provided on the front wall, an air inlet 120 and an air inlet fan 200 are provided on the door body 110, and an air outlet 130 and an air outlet fan 300 are provided on the rear wall, forming an air flow path in the front-rear direction. This design not only improves the operation convenience and maintenance efficiency of the cabinet, but also ensures that cold air can directly enter the interior of the cabinet body 100, and hot air can smoothly discharge from the cabinet body 100, improving the heat dissipation efficiency and the heat dissipation effect of the cabinet.

[0079] In some embodiments, the height of the air inlet 120 is different from the height of the air outlet 130.

[0080] If the heights of the air inlet 120 and the air outlet 130 are different, after the air enters the accommodation cavity through the air inlet 120, it will move a certain path along the height direction of the cabinet body 100 inside the cabinet body 100 to be discharged from the cabinet body 100 through the air outlet 130, so that the heat of the electrical components installed at different height positions inside the cabinet body 100 can be taken away to achieve a better heat dissipation effect.

[0081] In some embodiments, the air inlet 120 is close to the bottom end of the cabinet body 100, and the air outlet 130 is close to the top end of the cabinet body 100.

[0082] It is understandable that hot air will naturally rise due to its lower density, while cold air will naturally sink due to its higher density.

[0083] By setting the air inlet 120 at a lower position, cold air can more easily enter the interior of the cabinet body 100, forming an effective cooling effect; by setting the air outlet 130 at a higher position, hot air can more easily be discharged from the cabinet body 100, enhancing the effect of air flow, ensuring that excessive heat does not accumulate in the upper area of the equipment, and improving the heat dissipation efficiency.

[0084] Specifically, in the embodiment of the present application, by setting the air inlet 120 near the bottom end of the cabinet body 100 and the air outlet 130 near the top end of the cabinet body 100, the natural convection principle of cold air sinking and hot air rising can be fully utilized to form an efficient air circulation system. Cold air enters from the bottom and hot air is discharged from the top, ensuring a more uniform temperature distribution inside the cabinet body 100. This not only improves the efficiency of air flow but also helps to reduce the working burden of the fan, and overall improves the heat dissipation performance and reliability of the relay protection room screen cabinet.

[0085] Figure 4 It is a schematic structural diagram of the diversion structure installed on the door body in the relay protection room screen cabinet provided by the embodiment of the present application; Figure 5 is Figure 4 the enlarged view of part A in Figure 4 and Figure 5 As shown in

[0086] By setting the diversion structure 400 at the air inlet 120 and arranging a plurality of diversion openings 401 on the diversion structure 400, the cold air blown out by the air inlet fan 200 can be effectively guided to be more evenly distributed inside the cabinet body 100. The plurality of diversion openings 401 disperse the cold air into multiple airflows, ensuring a more uniform temperature inside the accommodation cavity, improving the utilization efficiency of the cold air, being beneficial for the electrical components to be fully cooled, and improving the heat dissipation performance and reliability of the relay protection room screen cabinet.

[0087] In some embodiments, the diversion structure 400 includes a frame 410 and a plurality of diversion plates 420 arranged on the inner side of the frame 410; the outer surface of the frame 410 abuts against the inner wall of the air inlet 120; the plurality of diversion plates 420 are arranged at intervals in sequence, and a diversion opening 401 is formed between two adjacent diversion plates 420.

[0088] The frame 410 can provide an installation space for the deflector 420. The deflector 420 can be stably installed on the frame 410, and the position of the deflector 420 corresponds to the position of the air inlet 120, capable of guiding the cold air entering the accommodation cavity through the air inlet 120, so as to make the cold air flow specifically to the position where the electrical components with greater heat generation are located, improving the heat dissipation effect.

[0089] In some embodiments, a plurality of deflectors 420 are arranged along the vertical direction ( Figure 2 the Z direction in Figure 2 ), and the extending direction of the deflector 420 is parallel to the horizontal direction (

[0090] the Y direction in

[0091] ). The deflector 420 is rotatably arranged on the frame 410, and the rotation axis of the deflector 420 is parallel to the horizontal direction to adjust the orientation of the diversion port 401.

[0092] By arranging the deflectors 420 along the vertical direction, a plurality of horizontal air flow channels can be formed, enabling the cold air to be dispersed to different heights of the cabinet 100, helping to avoid local overheating and improving the heat dissipation effect.

[0093] By designing the rotatable deflector 420, the flow direction of the air entering the accommodation cavity can be adjusted according to actual needs, ensuring that the cold air can more effectively cover the area to be cooled, improving flexibility and adjustability, and helping to optimize the heat dissipation effect.

[0094] The adjusting members 430 of the plurality of deflectors 420 are sequentially connected, so that the angles of the plurality of deflectors 420 can be adjusted simultaneously through one adjustment operation, improving the convenience and efficiency of the operation.

[0095] Combined with Figure 5 As shown, in some embodiments, the adjusting member 430 is set as an adjusting gear 431, and the adjusting gear 431 is rotatably arranged on the frame 410; the frame 410 is provided with an intermediate gear 432, and the intermediate gear 432 is arranged between two adjacent adjusting gears 431; the adjusting gears 431 of the plurality of deflectors 420 are sequentially meshed through the intermediate gear 432, so that the adjusting gears 431 of the plurality of deflectors 420 rotate synchronously.

[0096] It should be noted that gear transmission is a simple and reliable mechanical transmission method. By adjusting the rotation of gear 431, the angle of the deflector 420 can be precisely controlled, thereby changing the orientation of the diversion port 401 to ensure the optimal distribution of cold air.

[0097] Among them, the rotating shaft of the deflector 420 is rotatably connected to the frame 410. The adjusting gear 431 is fixedly connected to one end of the rotating shaft, and the adjusting gear 431 can be arranged outside the frame 410. Correspondingly, the intermediate gear 432 is also rotatably connected to the outside of the frame 410.

[0098] The number of teeth of the adjusting gear 431 and the intermediate gear 432 is the same, so that the rotation speed of each gear is the same, and the synchronous adjustment of the deflector 420 can be realized. The rotation angles of all deflectors 420 are the same, which can ensure the same flow direction of cold air.

[0099] An operating rod 433 can be arranged on one of the adjusting gears 431, and the operating rod 433 can be fixedly connected to the adjusting gear 431. Specifically, when implemented, by rotating the operating rod 433, the adjusting gear 431 can be driven to rotate, so as to drive the intermediate gear 432 and the remaining adjusting gears 431 that are meshed in sequence to rotate synchronously. When the adjusting gear 431 rotates, it can drive the rotation of the deflector 420, thereby realizing the synchronous rotation of multiple deflectors 420.

[0100] In some other embodiments, the number of teeth of each adjusting gear 431 and each intermediate gear 432 can be set to be different to change the transmission ratio between two adjacent gears. For example, from top to bottom, the number of teeth of the gears increases in sequence, so that the transmission ratio between two adjacent gears is less than 1. When adjusting, the rotation angle of the deflector 420 located above is greater than the rotation angle of the deflector 420 located below, so that the orientation of each diversion port 401 is different, which helps to further direct the cold air to more areas in the accommodation cavity.

[0101] Exemplarily, after the angle of the deflector 420 is adjusted, in order to prevent the deflector 420 from swinging under the action of gravity or air flow, an anti-slip sleeve can be lined between the rotating shaft of the deflector 420 and the frame 410 to increase the friction between the rotating shaft of the deflector 420 and the frame 410 and limit the swing of the deflector 420.

[0102] Of course, the rotation of the deflector 420 under the action of gravity or air flow can also be restricted by other structures, such as a ratchet structure, etc. The embodiments of the present application do not limit this.

[0103] In summary, the embodiment of the present application provides a relay protection room screen cabinet. By setting an intake fan 200 and an exhaust fan 300, a heat dissipation structure with forced air flow is formed on the cabinet body 100, which promotes the air outside the cabinet body 100 to enter the cabinet body 100 and promotes the hot air inside the cabinet body 100 to be discharged from the cabinet body 100, improving the air flow rate inside the cabinet body 100 and thus improving the heat dissipation efficiency. A flow guiding structure 400 is provided at the air intake 120, which can adjust the flow direction of the air entering the accommodation cavity according to actual needs, ensuring that the cold air can more effectively cover the area to be cooled, improving the flexibility and adjustability, and further improving the heat dissipation effect, thereby solving the problem of limited heat dissipation effect of the relay protection room screen cabinet.
