Description

Technical Field

[0001] The invention relates to the technical field of dehumidification and heat dissipation, and in particular to a switch cabinet with good dehumidification and heat dissipation effects. Background Art

[0002] High-voltage switchgear refers to the switch, control or protection functions used in power generation, transmission, distribution, power conversion and consumption of power systems. High-voltage switchgear is divided into several categories, including electrical products with voltage levels of 3.6kV550kV, high-voltage disconnectors and earthing switches, high-voltage load switches, high-voltage automatic reclosing and disconnecting devices, high-voltage operating mechanisms, high-voltage explosion-proof distribution devices and high-voltage switchgear.

[0003] In the prior art, the high-voltage switchgear is a closed structure. When the high-voltage switchgear is working, various electrical devices installed in the switchgear body work. When the electrical devices are working, heat is inevitably generated. A large amount of heat generated cannot be discharged out of the cabinet body in the closed space of the switchgear body. On the one hand, a large amount of heat will accelerate the aging of the electrical devices, shorten the service life of the electrical devices, and increase the cost. On the other hand, a large amount of heat is bound to cause the temperature inside the switchgear body to rise. When the temperature rises to a certain level, the electrical devices continue to work, which is prone to accidents such as fire, and there are safety hazards. Therefore, it is very necessary to set up a good ventilation and heat dissipation device.

[0004] At present, the heat dissipation of switch cabinets on the market is mainly to allow the internal air and the external air to flow, and take away the heat inside the switch cabinet during the flow. However, since the air contains dust that is invisible to the naked eye, the dust that enters the switch cabinet will be adsorbed on the surface of the electrical appliance due to static electricity. After long-term use and air flow, a large amount of dust will accumulate on the electronic components inside the switch cabinet, resulting in a decrease in the heat dissipation effect. Secondly, in summer, the air is also hot due to the temperature. At this time, allowing the air inside and outside the switch cabinet to flow will not only fail to cool down the cabinet, but will also cause the temperature inside the switch cabinet to rise.

[0005] In addition, due to the different geographical locations where the switch cabinet is used, humidity may occur inside the switch cabinet. Currently, most of the methods for dealing with humidity on the market are to heat up the inside of the switch cabinet to reduce the humidity inside the switch cabinet. However, when heating up the inside of the switch cabinet, the temperature of the internal electronic components will increase, causing the original heat dissipation effect to become even worse.

[0006] Therefore, in order to solve the dehumidification and heat dissipation problems inside the switch cabinet, we specially propose a switch cabinet with good dehumidification and heat dissipation effects. Summary of the invention

[0034] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0035] See also Figures 1 to 10 , the present invention provides a technical solution: A switch cabinet with good dehumidification and heat dissipation effect includes a main cabinet 1, a humidity monitor 101 is fixedly installed on the inner left side surface of the main cabinet 1, and a temperature monitor 102 is fixedly installed on the inner right side surface. The humidity monitor 101 can monitor the humidity inside the main cabinet 1 in real time. When the humidity inside the main cabinet 1 reaches a preset value, its dehumidification structure will operate to dehumidify the inside of the main cabinet 1.

[0036] The temperature monitor 102 can monitor the humidity inside the main cabinet 1 in real time. When the temperature inside the main cabinet 1 reaches a preset value, the cooling structure will operate to cool the inside of the main cabinet 1, thereby ensuring the temperature and humidity inside the main cabinet 1 and ensuring that the main cabinet 1 can operate with maximum efficiency.

[0037] A connection port 113 is provided from the bottom surface of the main cabinet 1 to the outside, and two first installation slots 103 are provided from the lower front side of the main cabinet 1 to the inside, wherein the length and width of the first installation slots 103 are greater than the connection port 113. Figure 6 As shown, a first filter plate 105 is slidably installed inside the upper first mounting groove 103, and a second filter plate 106 is slidably installed inside the lower first mounting groove 103, wherein the filter hole diameter of the first filter plate 105 is smaller than that of the second filter plate 106, and the filter holes on the first filter plate 105 and the second filter plate 106 are staggered with each other, so as to ensure the filtering effect of dust in the air.

[0038] Two air outlets 107 are provided from the top to the inside of the main cabinet 1, and a first motor 108 is installed at the center of the two air outlets 107 using a connecting rod, and a first fan blade 109 is fixedly installed on the output shaft of the first motor 108. Figure 7 As shown, Start the first motor 108, and the output shaft of the first motor 108 will drive the first fan blade 109 to rotate. During the rotation of the first fan blade 109, the internal air of the main cabinet 1 can continuously flow upward, and then pass through the air outlet 107, so that the heat inside the main cabinet 1 can be discharged from the inside of the main cabinet 1.

[0039] An L-shaped air outlet pipe 110 is fixedly installed at the outer edge of the two air outlet holes 107 on the top of the main cabinet 1. The air passing through the air outlet holes 107 will enter the interior of the L-shaped air outlet pipe 110, and two closing plates 111 are rotatably installed at the ends of the two L-shaped air outlet pipes 110 that are away from each other. Among them, the two adjacent closing plates 111 can seal the upper outlet position of the L-shaped air outlet pipe 110 to prevent dust from entering the interior, thereby preventing dust from entering the interior of the main cabinet 1. It should be noted that a return spring is used at the position where the closing plate 111 is rotatably connected to the L-shaped air outlet pipe 110, so as to prevent the closing plates 111 at the lower ends on the left and right sides from falling off, resulting in the outlet position of the L-shaped air outlet pipe 110 being unable to be closed.

[0040] During use, due to the operation of the first motor 108, the airflow generated can blow the two adjacent closed plates 111 to rotate, so that the outlet of the L-shaped air outlet pipe 110 can be in an open state, so that the hot air inside the main cabinet 1 can pass through the air outlet hole 107, enter the interior of the L-shaped air outlet pipe 110, and then flow out.

[0041] An air inlet box 2 is fixedly installed at the lower end of the main cabinet 1 . The interior of the air inlet box 2 is a cavity structure, and the top is open, so the air inlet box 2 is in a through state with the main cabinet 1 .

[0042] Air inlet holes 201 are opened on the left and right sides of the air inlet box 2. A second motor 207 is fixedly installed with a connecting rod at the inner center position of the air inlet hole 201. A second fan blade 208 is fixedly installed on the output shaft of the second motor 207. Steel wire meshes are fixedly installed at the inner edges of the left and right air inlet holes 201 to block larger impurities, thereby ensuring the safe operation of the second motor 207 and the second fan blade 208.

[0043] Two through holes 202 in an inclined state are provided from the front end surface to the inside of the air inlet box 2, and four U-shaped frames 203 are fixedly installed inside the air inlet box 2, wherein the U-shaped frames 203 are arranged in groups of two, such as Figure 4 As shown, the upper and lower adjacent U-shaped frames 203 and the through holes 202 are in an aligned state.

[0044] Therefore, during use, the interlayer filter plate 204 can pass through the through hole 202 into the interior of the air inlet box 2, and then maintain an inclined state under the action of the upper and lower U-shaped frames 203, so that the first filtering operation can be performed on the air entering the air inlet box 2.

[0045] Secondly, a mounting groove 205 is opened in the interlayer of the interlayer filter plate 204, and a row of cold pipes 206 are fixedly installed inside the mounting groove 205. When the outside air is filtered by the interlayer filter plate 204, the cold pipes 206 can cool the passing air, so that the hot air can be lowered in the summer to ensure that the hot air does not enter the interior of the main cabinet 1.

[0046] Secondly, two symmetrical guide plates 209 are fixedly installed inside the air inlet box 2 between the left and right interlayer filter plates 204. Under the action of the guide plates 209, the air entering from the left and right sides will not collide with each other, thereby preventing the outside air from entering from the air inlet hole 201 on the left and going out from the air inlet hole 201 on the right, ensuring that the air can smoothly enter the interior of the main cabinet 1, and can guide the air to flow upward. A plurality of adsorption activated carbon beads 210 are evenly fixedly installed between the two upper U-shaped frames 203. The adsorption activated carbon beads 210 can adsorb moisture in the passing air, thereby ensuring that moisture in the air will not enter the interior of the main cabinet 1, and ensuring that the air will not cause damage to the electronic components inside the main cabinet 1.

[0047] Rectangular holes 112 are provided on the left and right sides of the main cabinet 1, and protective covers 301 are fixedly installed on the left and right sides of the main cabinet 1. A condenser 312 is fixedly installed on the top of the protective cover 301. An L-shaped air intake cover 306 is fixedly installed on the upper end of the inner part of the protective cover 301. The front end of the air intake cover 306 can pass through the rectangular hole 112 and the interior of the main cabinet 1. Then, a third motor 307 is fixedly installed on the left side of the rear end of the air intake cover 306, and a third fan blade 308 is fixedly installed on the output shaft of the third motor 307. Figure 8 and Fig. 9 shown.

[0048] During use, the third motor 307 is started, and the output shaft of the third motor 307 can rotate with the third fan blade 308 . During the rotation, the moisture inside the main cabinet 1 can pass through the rectangular hole 112 and enter the interior of the air intake hood 306 .

[0049] A condensation box 309 is fixedly installed at the lower end of the air inlet hood 306, and a mounting plate 310 is fixedly installed at the upper end of the interior of the condensation box 309, and a plurality of condensation tubes 311 are evenly fixedly installed from the upper end to the lower end of the mounting plate 310, wherein circular holes matching the condensation tubes 311 are provided from the upper end surface to the lower end surface of the mounting plate 310, and each condensation tube 311 is plugged into the inside of the circular hole, and the mounting plate 310 ensures that moisture can smoothly enter the inside of the condensation tube 311 without slipping through the gaps between the condensation tubes 311, resulting in the inability to liquefy the moisture.

[0050] It should be noted that there is a certain distance between the condensation box 309 and the inner bottom surface of the protective cover 301, such as Figure 8 As shown, the inner bottom surface of the condensation box 309 is provided with a circular hole matching the condensation tube 311, so as to allow the liquefied liquid to flow into the interior of the protective cover 301. At this time, during the operation, the moisture entering the condensation box 309 will gradually enter the interior of the condensation tube 311. At this time, due to the start-up of the condenser 312, the internal temperature of the condensation tube 311 is below the hour, so that the moisture can be liquefied. Due to the low temperature, the moisture continues to liquefy, and the liquefied water will flow along the condensation tube 311 into the inner bottom surface of the protective cover 301.

[0051] A water pump 302 is fixedly installed at the lower end of the protective cover 301, a filter cartridge 303 is fixedly installed at the lower end of the water pump 302 by using flanges, bolts and nuts, and a water outlet nozzle 304 is fixedly installed at the lower end of the filter cartridge 303 by using flanges, bolts and nuts. Figure 8 Secondly, a rectangular frame 305 is fixedly installed on the left and right sides of the air inlet box 2, and the lower end of the water outlet nozzle 304 is located inside the rectangular frame 305.

[0052] When in use, starting the water pump 302 can extract the liquefied water inside the protective cover 301, and the extracted water will be filtered by the filter barrel 330 and sprayed out through the water outlet nozzle 304. During the spraying process, the air entering the rectangular frame 305 can be cooled, thereby realizing the secondary utilization of resources.

[0053] Working principle: First, the humidity monitor 101 and the temperature monitor 102 can monitor the internal humidity and temperature of the main cabinet 1 in real time. When the temperature exceeds a preset value, the first motor 108 is started, and the output shaft of the first motor 108 rotates with the first fan blade 109, so that the hot air inside the main cabinet 1 can move downward, and the air passes through the air outlet 107 into the interior of the L-shaped air outlet pipe 110, and then flows out of the interior of the L-shaped air outlet pipe 110.

[0054] The second motor 207 is started, and the output shaft of the second motor 207 rotates with the second fan blade 208 , so that the outside air can pass through the rectangular frame 305 and the air inlet hole 201 into the interior of the air inlet box 2 .

[0055] The incoming air will be filtered for the first time by the sandwich filter plate 204. When the air passes through the cold pipe 206, the cold pipe 206 cools the air, and then the air flows upward along the guide plate 209.

[0056] After the air moves upward, the activated carbon beads 210 will absorb the moisture in the air, and then the air will pass through the second filter plate 106 and the first filter plate 105 in sequence. Under the action of the first filter plate 105 and the second filter plate 106, the air is filtered for the second time to ensure that dust does not enter the interior of the main cabinet 1. The filtered cold air then enters the interior of the main cabinet 1 to cool the interior of the main cabinet 1. In addition, with the action of the first motor 108 on the top, the internal air can flow.

[0057] When the humidity exceeds a preset value, the third motor 307 is started, and the output shaft of the third motor 307 rotates with the third fan blade 308, allowing the humid air inside the main cabinet 1 to pass through the rectangular hole 112 into the air intake hood 306, and then enter the condensation box 309.

[0058] Start the condenser 312. Under the action of the condenser 312, the air entering the condenser tube 311 can be liquefied. The liquefied liquid is stored inside the protective cover 301. When necessary, start the water pump 302 to allow the liquid to enter the filter tube 303, and then be sprayed out by the water outlet nozzle 304 to cool the air entering the rectangular frame 305.

[0059] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the aforementioned embodiments, or replace some or all of the technical features therein with equivalents.
