Abstract
Description
Technical Field
[0001] The present invention relates to the technical field of power equipment, and particularly relates to a dust-proof and heat-dissipating switch cabinet. Background Art
[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 a power system. The external wires of the switch cabinet first enter the main control switch inside the cabinet, and then enter the sub-control switch, and each branch is set as required.
[0003] The main function of the switch cabinet is to open, close, control, and protect electrical equipment during the processes of power generation, power transmission, power distribution, and power conversion in a power system; the components inside the switch cabinet mainly include a circuit breaker, a disconnector, a load switch, an operating mechanism, an instrument transformer, and various protection devices, etc.
[0004] As can be seen from the above introduction, there are many electrical components inside the switch cabinet, and the use environment is relatively harsh. In order to dissipate heat, the existing switch cabinets generally leave gaps at the joint of the cabinet door when assembling the cabinet body for air intake and heat dissipation. However, due to the relatively harsh use environment of the switch cabinet, dust can easily enter the cabinet body of the switch cabinet and accumulate on the electrical components inside the cabinet. Since the components inside the cabinet are arranged relatively closely, when the dust accumulates to a certain amount, it will generate a certain amount of static electricity, or seriously affect the heat dissipation effect of the electrical components themselves.
[0005] In addition, most of the current switch cabinets are composed of multiple sealed boxes fixedly installed together. When in use, each individual box inside the switch cabinet will generate a relatively high amount of heat. However, the current switch cabinets have a poor heat dissipation effect and cannot timely dissipate the heat generated by the electrical components inside each individual box, seriously affecting the normal operation of the electrical components inside the switch cabinet, thereby shortening the service life of the electrical components inside the high- and low-voltage switch cabinets.
[0006] Some current cabinets are equipped with exhaust fans, which can make some flowing air currents inside the cabinet and play a certain heat dissipation effect. However, due to the poor sealing performance of the cabinet body itself, the air currents generated inside the cabinet are not large, and for some components with large heat dissipation, the air current cannot flow through their positions alone.
[0007] Therefore, how to improve the heat dissipation performance and dust removal performance of the switch cabinet and ensure the normal operation of the switch cabinet is the direction that those skilled in the art have been working hard on. Summary of the Invention

[0054] Embodiment 1
[0055] As Figures 1 to 16 shown, the present invention discloses a dust-proof and heat-dissipating switch cabinet, including:
[0056] A cabinet body 1, in which a partition 14 is arranged. Above the partition 14, an electrical component installation area 18 is formed, and below the partition 14, a cooling area 19 is formed.
[0057] An upper sealing door 2, used to close the electrical component installation area 18, and the upper sealing door 2 can be rotated to open.
[0058] A lower sealing door 3, used to close the cooling area 19, and the lower sealing door 3 can be rotated to open.
[0059] A heat-dissipating device, arranged inside the cabinet body 1, including a sliding heat storage device 13 and a track device. The sliding heat storage device 13 can slide or be fixed on the track device, and the sliding heat storage device 13 can switch between the electrical component installation area 18 and the cooling area 19.
[0060] An air-cooling device, including a air supply device 6. The air supply device 6 is used to supply air into the cooling area 19 to perform air-cooling heat dissipation on the sliding heat storage device 13 in the cooling area 19, and the heat-dissipated air is discharged through an air outlet 10 arranged in the cooling area 19.
[0061] Among them, the sliding heat storage device 13 can absorb the heat dissipated by the electrical components in the electrical component installation area 18. When the heat storage heat exchange plate 1303 on the sliding heat storage device 13 reaches the preset heat exchange temperature or preset deformation amount, the sliding heat storage device 13 can slide on the track device under the action of the control device and slide to the cooling area 19, and then be air-cooled by the air supply device 6 in the cooling area 19. After cooling, the sliding heat storage device 13 slides back into the electrical component installation area 18 again.
[0062] In the dust-proof and heat-dissipating switch cabinet disclosed in the present invention, by arranging the sliding heat storage device 13 and the track device, the heat storage heat exchange plate 1303 stores heat when the electrical components in the electrical component installation area 18 dissipate heat. When the heat storage reaches a certain threshold, it can slide to the cooling area 19 under the action of the control device to realize heat exchange and cooling of the heat storage heat exchange plate 1303 after heat storage. When the heat storage heat exchange plate 1303 returns to the low-temperature heat exchange temperature or the original shape, the cooling of the heat storage heat exchange plate 1303 is realized. The sliding heat storage device 13 slides back into the electrical component installation area 18 again to absorb the heat dissipated by the electrical components in the electrical component installation area 18. The sliding heat storage device 13 can slide or be fixed at any position on the track device under the action of the control device.
[0063] The dust-proof and heat-dissipating switch cabinet disclosed in the present invention has a clever structure. Under the condition that the cabinet body of the switch cabinet 100 is relatively well sealed, by arranging the sliding heat storage device 13 and the track device, the heat storage heat exchange plate 1303 on the sliding heat storage device 13 can absorb the heat dissipated by the electrical components in the electrical component installation area 18 and move to the cooling area 19 for cooling, avoiding sudden increase or decrease of the temperature inside the electrical component installation area 18. It can not only fully dissipate the heat of the components in the cabinet, but also ensure the stable operation of the electrical components. Moreover, during heat dissipation, the dust removal effect can be ensured, and the problems of heat dissipation and dust removal are solved at the same time.
[0064] As a preferred example of the present invention, the track device includes a first sliding track 11, a first steering track 12, a first connecting track 16, a second steering track 17 and a second connecting track 20. The first sliding track 11 and the first steering track 12 are arranged in the electrical component installation area 18. The first steering track 12 is used to steer and guide the sliding heat storage device 13 on the first sliding track 11. The second steering track 17 and the second connecting track 20 are arranged in the cooling area 19. The second steering track 17 is used to steer and guide the sliding heat storage device 13 on the first connecting track 16 or the second connecting track 20. The first connecting track 16 is used to connect the first steering track 12 and the second steering track 17.
[0065] As a preferred example of the present invention, multiple rows of the first sliding tracks 11 are provided, and a first turning track 12 is provided at the end of each row of the first sliding tracks 11. Adjacent two first turning tracks 12 can be transferred to be collinear, so as to realize the transfer of the sliding heat storage device 13 between the two first sliding tracks 11; the sliding heat storage device 13 on the first sliding track 11 close to the cooling area 19 can be transferred to the first connecting track 16 through the first turning track 12 provided at the end of this first sliding track 11, and then can be transferred to the second turning track 17 under the action of the control device. The sliding heat storage device 13 on the second turning track 17 can be transferred to and fixed on the second connecting track 20 corresponding to this second turning track 17, or the sliding heat storage device 13 on the second turning track 17 can be transferred to another second turning track 17 adjacent to this second turning track 17. Multiple rows of the second connecting tracks 20 are provided, and a second turning track 17 is provided at the end of each row of the second connecting tracks 20.
[0066] This setting discloses a specific structure of the track device, enabling the sliding heat storage device 13 to reliably and accurately appear at more positions in the electrical component installation area 18 and the cooling area 19, meeting the needs of heat dissipation, heat exchange, cooling and cooling.
[0067] As a preferred example of the present invention, the sliding heat storage device 13 includes a sliding block 1301, and a support frame 1302 is arranged on the sliding block 1301. The support frame 1302 is used to support and fix the heat storage and heat exchange plate 1303. The sliding block 1301 and the track device slide relative to each other or are fixed through a gear and rack structure.
[0068] This setting realizes the relative sliding or fixing of the sliding heat storage device 13 and the track device through the sliding structure of the gear and rack, with reasonable structure, easy to implement, reliable transmission and stable fixation.
[0069] Preferably, the sliding block 1301 includes a sliding plate body 13011. A first sliding side wall 13012 is arranged at one end of the sliding plate body 13011, and a second sliding side wall 13013 is arranged at the other end of the sliding plate body 13011. A guiding block structure is arranged on the first sliding side wall 13012 and / or the second sliding side wall 13013, and a guiding groove device is arranged on the track device. During the sliding process of the sliding heat storage device 13, the guiding block structure is guided and limited by the guiding groove device.
[0070] This setting further improves the smoothness and reliability of the movement of the sliding heat storage device 13 during the sliding process.
[0071] Specifically, taking the first sliding track 11 as an example, the first sliding track 11 includes a first track main body 1101. First guiding grooves 1102 are provided on both the upper and lower surfaces of the first track main body 1101. A first groove 1103 is provided on the front surface of the first track main body 1101, and a first rack 1104 is provided in the first groove 1103. A first guiding block 13014 is provided on one side of the first sliding side wall 13012 close to the second sliding side wall 13013, and a second guiding block 13015 is provided on one side of the second sliding side wall 13013 close to the first sliding side wall 13012. The first guiding block 13014 and the second guiding block 13015 can respectively extend into the first guiding grooves 1102 provided on the upper and lower sides of the first track main body 1101 for limiting. A sliding gear 13016 is provided on the side surface of the sliding plate body 13011 away from the regenerative heat exchange plate 1303. The sliding gear 13016 is connected to a motor (not shown in the figure) and rotates under the action of a control device. The sliding gear 13016 extends out of the surface of the sliding plate body 13011 and can be meshed and connected with the first rack 1104 on the first sliding track 11.
[0072] This setting discloses a specific structure for the sliding movement of the sliding regenerative heat storage device 13 and the first sliding track 11, with reasonable structure, smooth, reliable sliding and easy to control.
[0073] As a preferred example of the present invention, the first turning track 12 includes a second track main body 1201, and the second track main body 1201 can perform an integral rotational movement under the driving action of the rotating shaft 1204.
[0074] Specifically, the rotating shaft 1204 is driven by a motor, and the rotating shaft 1204 and the second track main body 1201 are connected through gear meshing. When the rotating shaft 1204 rotates driven by the motor, the second track main body 1201 rotates together therewith.
[0075] As a preferred example of the present invention, second guiding grooves 1202 are provided on both side surfaces of the second track main body 1201, and a second rack 1203 is provided on the front surface of the second track main body 1201. The second rack 1203 is arranged corresponding to the first rack 1104 on the first sliding track 11.
[0076] This setting enables the sliding heat storage device 13 to slide onto the first turning track 12 when it slides to the end on the first sliding track 11. Then, under the rotational movement of the first turning track 12, the sliding heat storage device 13 on the first turning track 12 can be transferred to another adjacent first turning track 12 or the first connecting track 16, realizing the transformation of the sliding heat storage device 13 in different directions or positions. This setting has a clever structure, reliable turning, convenient operation, and is easy to control.
[0077] As a preferred example of the present invention, a first avoidance gap 1206 is provided between the second track body 1201 and the first track body 1101, and an avoidance bevel 1205 is provided at one end of the second track body 1201 away from the rotating shaft 1204. This setting prevents the second track body 1201 from being obstructed by the first track body 1101 during rotation, ensuring the reliability of the turning of the first turning track 12.
[0078] As an example of the present invention, the structure of the second turning track 17 is similar to that of the first turning track 12, and the structure of the second connecting track 20 is similar to that of the first sliding track 11, which will not be elaborated here one by one.
[0079] As an example of the present invention, a through hole 15 is provided on the partition 14, a sliding sealing plate 21 is provided at the position of the through hole 15, at least one end of the first connecting track 16 extends out of the through hole 15, and the sliding sealing plate 21 can open or close the through hole 15.
[0080] Specifically, a second sliding track 22 is provided at the through hole 15. The second sliding track 22 is provided on the upper surface of the partition 14. The first connecting track 16 includes an upper connecting track 1601 and a lower connecting track 1602. The upper connecting track 1601 is provided above the partition 14. A second avoidance gap 1603 is provided between the upper connecting track 1601 and the lower connecting track 1602. When the sliding sealing plate 21 slides on the second sliding track 22, it can be inserted into the second avoidance gap 1603.
[0081] This setting enables the electrical component installation area 18 and the cooling area 19 to be relatively isolated. The cooling air introduced by the air cooling device mainly conducts air cooling on the sliding heat storage device 13 after heat storage in the cooling area 19. The cooling air or the heat dissipation air will not flow towards the electrical component installation area 18, thereby ensuring reliable heat dissipation in the electrical component installation area 18 and avoiding dust inflow at the same time, achieving the purpose of dust prevention.
[0082] As a preferred example of the present invention, the support frame 1302 includes a vertical support rod 13021, a first horizontal support rod 13022 is arranged at the upper end of the vertical support rod 13021, and a second horizontal support rod 13023 is arranged at the lower end of the vertical support rod 13021. The heat storage and heat exchange plate 1303 is arranged in a flexible manner, and the upper and lower ends of the heat storage and heat exchange plate 1303 are respectively inserted and connected to the first horizontal support rod 13022 and the second horizontal support rod 13023.
[0083] Specifically, the vertical support rod 13021 is arranged on the side of the sliding plate body 13011 away from the sliding gear 13016. The heat storage and heat exchange plate 1303 includes two heat exchange membranes, namely a first heat exchange membrane and a second heat exchange membrane. The two heat exchange membranes are fixedly formed into a plurality of upper heat storage and heat exchange bags 13031 and lower heat storage and heat exchange bags 13032 by welding. A heat storage material is sealed in the upper heat storage and heat exchange bags 13031 and the lower heat storage and heat exchange bags 13032.

[0104] S4: The control module notifies the operator through the communication circuit and presets a waiting time t. If the operator arrives for processing within the preset time, step S5 is executed; if the operator does not process within the preset time t, the smoke alarm gives an audible and visual alarm;
[0105] S5: The operator remotely controls the detection of the switch cabinet failure situation and executes the corresponding solution procedure;
[0106] S6: When the temperature of the sliding heat storage device drops to T 低 , and / or the number of touches of the upper heat storage and heat exchange part and the lower heat storage and heat exchange part is 0, the control module controls the sliding heat storage device to slide into the electrical component installation area on the track device;
