Description

Technical Field

[0001] The utility model relates to the technical field of switch cabinets, and specifically relates to a switch cabinet for power transmission and distribution. Background Technique

[0002] A switch cabinet is an electrical device, and its main function is to open, close, control, and protect electrical equipment during the processes of power generation, power transmission, power distribution, and power conversion in the power system. It can be divided into high-voltage switch cabinets, medium-voltage switch cabinets, low-voltage switch cabinets, etc. according to different voltage levels. It is mainly applicable to various different occasions such as power plants, substations, petrochemical industries, metallurgical rolling mills, light industry and textile industries, factories and mines, residential communities, high-rise buildings, etc.

[0003] The switch cabinet is often used in the power transmission and distribution process of substations. The cabinet body mainly relies on the heat dissipation holes on both sides for natural heat dissipation. However, the heat dissipation effect only relying on the heat dissipation holes is poor, which will cause the problem of untimely heat dissipation and heat removal, and then lead to a relatively high temperature inside the cabinet. This will indirectly cause damage to the internal components of the switch cabinet, and may seriously affect the normal use of the substation, posing a relatively large potential safety hazard. Therefore, we propose a switch cabinet for power transmission and distribution to solve the above problems. Content of the Utility Model

A heat dissipation fan is detachably installed in the ventilation grooves, and a dust-proof net is covered and installed at the front opening of the ventilation grooves.

[0006] As a further optimized solution of the utility model, a plurality of limiting blocks distributed in an array are installed inside the ventilation grooves. The heat dissipation fan is detachably installed between the plurality of limiting blocks, and a limiting member is installed on the limiting blocks to stabilize the heat dissipation fan through the limiting member.

[0007] As a further optimized solution of the utility model, a limiting groove is opened on one side of the limiting block close to the center of the ventilation groove. The side of the limiting groove close to the opening of the ventilation groove is an open end, and the open end is adapted to the outer edge of the heat dissipation fan. The outer edge of the heat dissipation fan is clamped with a plurality of limiting grooves, and the limiting member is installed outside the open end and limits the edge of the heat dissipation fan.

[0008] As a further optimized solution of the utility model, the limiting member includes a rotating column and a baffle. The rotating column is rotatably installed on the limiting block and is located outside the limiting groove, and the baffle is installed on the rotating column. By rotating the rotating column, the baffle is driven to move to the outside of the limiting groove to press and limit the outer edge of the heat dissipation fan.

[0009] As a further optimized solution of the present utility model, a limiting hole is provided at one end of the rotating column away from the limiting block, and a limiting post corresponding to and adapted to the limiting hole is installed on the back surface of the dust-proof net. The dust-proof net covers the opening of the ventilation groove, and the limiting post is tightly inserted into the limiting hole.

[0010] As a further optimized solution of the present utility model, the baffle is made of iron, and a magnet corresponding to the limiting groove is installed on the back surface of the dust-proof net. The back surface of the dust-proof net is magnetically fixed to the baffle through the magnet.

[0011] As a further optimized solution of the present utility model, a storage groove corresponding to and adapted to the baffle is provided on the inner wall of the ventilation groove, and the baffle is rotated by the rotating column and transferred into the storage groove for storage.

[0012] As a further optimized solution of the present utility model, the dust-proof net includes a frame and a filter screen. The filter screen is installed in the inner circle of the frame. The frame covers the opening of the ventilation groove, and the area of the frame is larger than the area of the opening of the ventilation groove.

[0015] By providing a ventilation groove on the outer wall of the cabinet body and installing a heat dissipation fan in the ventilation groove, the present utility model utilizes the rotation of the heat dissipation fan to accelerate the air flow rate inside the cabinet body, which is beneficial to the timely discharge of heat, thereby improving the heat dissipation effect inside the cabinet body, avoiding damage to components caused by too high temperature inside the cabinet body, reducing potential safety hazards, facilitating the normal use of the substation, and by installing a dust-proof net at the opening of the ventilation groove, it can also play a certain dust-proof role while not affecting the air-cooled heat dissipation, which is beneficial to the normal use of the cabinet body.

[0028] Please refer to Figures 1 - 5 , a switch cabinet for power transmission and distribution, mainly used for power transmission and distribution in substations, specifically including a cabinet body 1. Ventilation slots 2 communicating with its inner cavity are provided on the outer wall of the cabinet body 1. A heat dissipation fan 3 is detachably installed in the ventilation slots 2, and a dust-proof net 4 is covered and installed at the front opening of the ventilation slots 2;

[0029] The number of the ventilation slots 2 is multiple and they are evenly distributed on the back of the cabinet body 1. Both sides of the cabinet body 1 are provided with heat dissipation holes with traditional designs. The heat dissipation fan 3 is installed in the ventilation slots 2 and is connected to the power supply inside the cabinet body 1 through a wire. After being powered on, the heat dissipation fan 3 rotates. The outside air enters the cabinet body 1 after being filtered by the dust-proof net 4, and the air inside the cabinet body 1 is discharged outward from the heat dissipation holes on both sides, which can accelerate the air flow rate inside the cabinet body 1, realize air-cooled heat dissipation, and thus improve the actual heat dissipation effect;

[0030] Specifically, as Figure 2 shown, a plurality of limiting blocks 5 distributed in an array are installed inside the ventilation slots 2. The heat dissipation fan 3 is detachably installed between the plurality of limiting blocks 5, and limiting members are installed on the limiting blocks 5 to stabilize the heat dissipation fan 3;

[0031] Furthermore, as Figure 3 shown, a limiting groove 11 is provided on one side of the limiting block 5 close to the center of the ventilation slot 2. The side of the limiting groove 11 close to the opening of the ventilation slot 2 is an open end, and the open end is adapted to the outer edge of the heat dissipation fan 3. The outer edge of the heat dissipation fan 3 is clamped with a plurality of limiting grooves 11, and the limiting member is installed outside the open end to limit the edge of the heat dissipation fan 3;

[0032] Furthermore, the ventilation slots 2 are rectangular grooves. The number of the limiting blocks 5 is four and they are respectively installed on the inner walls at the four corners of the ventilation slots 2. The outer frame shape of the heat dissipation fan 3 is rectangular, and the four corners of the heat dissipation fan 3 are respectively clamped with the adjacent limiting grooves 11, which can realize the quick installation of the heat dissipation fan 3;

[0033] Further, the limiting member includes a rotating column 6 and a baffle 7. The rotating column 6 is rotatably installed on the limiting block 5 and is located outside the limiting groove 11. The baffle 7 is installed on the rotating column 6. By rotating the rotating column 6, the baffle 7 is driven to move outside the limiting groove 11 to press and limit the outer edge of the cooling fan 3. The limiting member can also be a buckle, a bolt or a screw in the prior art, etc.;

[0034] The four baffles 7 press and cover the four corners of the cooling fan 3 respectively, so that the cooling fan 3 can be stably installed between the four limiting blocks 5, and at the same time, it is convenient for disassembly, assembly, inspection and maintenance;

[0035] Further, a limiting hole 9 is opened at one end of the rotating column 6 away from the limiting block 5. A limiting post 8 corresponding to and adapted to the limiting hole 9 is installed on the back surface of the dust-proof net 4. The dust-proof net 4 covers the opening of the ventilation groove 2, and the limiting post 8 is tightly inserted into the limiting hole 9, which is convenient to stably cover the dust-proof net 4 on the opening of the ventilation groove 2;

[0036] The limiting post 8 and the limiting hole 9 can be fastened by friction or stabilized by magnetic attraction;

[0037] Further, the baffle 7 is made of iron, and a magnet 10 corresponding to the limiting groove 11 is installed on the back surface of the dust-proof net 4. The back surface of the dust-proof net 4 is magnetically fixed to the baffle 7 by the magnet 10, which can further improve the installation stability of the dust-proof net 4;

[0038] Further, a receiving groove 12 corresponding to and adapted to the baffle 7 is opened on the inner wall of the ventilation groove 2. By rotating the rotating column 6, the baffle 7 is driven to be transferred into the receiving groove 12 for storage;

[0039] When installing the cooling fan 3, it is necessary to first rotate the four baffles 7 so that the baffles 7 move to the peripheral area of the limiting groove 11. The baffles 7 are transferred into the receiving groove 12 for storage, and the front opening of the limiting groove 11 is exposed. Then, the four corners of the cooling fan 3 are respectively inserted into the adjacent limiting grooves 11 to complete the assembly between the cooling fan 3 and the four limiting blocks 5.

[0040] Specifically, the dust-proof net 4 includes a frame 41 and a filter screen 42. The filter screen 42 is installed in the inner circle of the frame 41. The frame 41 covers the opening of the ventilation groove 2, and the area of the frame 41 is larger than the opening area of the ventilation groove 2, which can prevent dust from entering the cabinet 1 through the gap between the ventilation groove 2 and the dust-proof net 4. Moreover, the outer edge of the frame 41 extends to the peripheral area of the ventilation groove 2, which is convenient for removing the dust-proof net 4;

[0041] Specifically, as Figure 5As shown in the figure, a ventilation opening 13 is provided on one side of the ventilation groove 2 close to the inner cavity of the cabinet body 1. The ventilation opening 13 is communicated with the inner cavity of the ventilation groove 2. The motor driving part of the heat dissipation fan 3 is located at the center of the ventilation opening 13, which not only facilitates the connection of the motor to the power supply inside the cabinet body 1, but also facilitates air circulation and improves the heat dissipation effect.

[0042] In summary, for the switch cabinet for power transmission and distribution proposed by the present utility model, by opening the ventilation groove 2 on the outer wall of the cabinet body 1 and installing the heat dissipation fan 3 in the ventilation groove 2, the rotation of the heat dissipation fan 3 is used to accelerate the air flow rate inside the cabinet body 1, which is beneficial to the timely discharge of heat, thereby improving the heat dissipation effect inside the cabinet body 1, avoiding damage to components caused by too high temperature inside the cabinet body 1, reducing potential safety hazards, and facilitating the normal use of the substation. Moreover, by installing a dust-proof net 4 at the opening of the ventilation groove 2, it can play a certain dust-proof role while not affecting the air-cooled heat dissipation, which is beneficial to the normal use of the cabinet body 1.
