Description

Technical Field

[0001] The utility model relates to the technical field of electrical equipment, in particular to an anti-condensation device. Background Art

[0002] As the most basic component of the distribution network, distribution stations are widely distributed and numerous. The 10kV switchgear in the station is the most direct equipment for supplying power to users. Its operating status is related to the quality and reliability of power supply. Experience shows that most distribution rooms have long-term problems such as poor air quality and humid environment. In particular, the air humidity in the switchgear is high, which can easily cause discharges between phases and between phases and ground of the busbar, as well as condensation on the inner wall of the cabinet, causing bushing creepage and flashover failures.

[0003] After searching, Chinese patent publication (announcement) number CN219086495U discloses a condensation-proof ventilation ring network cabinet, including a protective outer frame, a ring network cabinet body and a heat dissipation top frame, the ring network cabinet body is arranged inside the protective outer frame, a dehumidification structure is installed at the lower part of the two ends of the protective outer frame, both sides of the ring network cabinet body are provided with a fastening structure, the top of the protective outer frame is fixedly connected with the heat dissipation top frame, the top of the protective outer frame is provided with a heat dissipation groove, both sides of the heat dissipation top frame are provided with exhaust fans, and the top of the heat dissipation groove is provided with a dustproof structure. The utility model is provided with a dehumidification structure, because absorbent cotton is filled in the interior of the installation frame, and the absorbent cotton stably filters the air entering the ring network cabinet under the installation of the installation frame and the mesh cover, so that the moisture in the humid air is absorbed by the absorbent cotton, thereby preventing the surface of the ring network cabinet body from condensing during the air flow inside the protective outer frame, thereby achieving dehumidification of the flowing air.

[0004] Although the above patent can absorb moisture in the air through washing cotton, as the use time of the absorbent cotton increases, the cotton fibers will become full, resulting in a decrease in water absorption capacity, and the water absorption effect of the absorbent cotton will gradually weaken. In addition, the absorbent cotton absorbs and retains a large amount of moisture, causing it to become dense and easy to gather together, thereby hindering the free flow of air and making it difficult for outside air to enter the cabinet. Therefore, it is necessary to design an anti-condensation device to solve the above problems. Utility Model Content

[0026] During specific use, through the arrangement of the induced ventilator 2, refrigerator 4, condensing sheet 5, drain pipe 7, heating end 8, heater 9 and exhaust fan 11, when the induced ventilator 2 is started, the external air enters the interior of the air duct 3 through the through hole 13, the refrigerator 4 is turned on to reduce the temperature of the condensing sheet 5, and the external humid air encounters cold on the condensing sheet 5 to produce condensation and cool down, thereby obtaining low-temperature dry air, the guide plate 6 guides the condensed water and discharges it to the outside through the drain pipe 7, and then initially heats up the air under the action of the heating end 8 of the refrigerator 4, the heater 9 heats the initially heated air to an appropriate temperature, and finally the dry air is transported to the interior of the shell 1 under the action of the exhaust fan 11, which effectively improves the dryness of the air and can prevent the air temperature in the equipment from being too low to cause condensation, thereby playing a role in dehumidification and anti-condensation, and the heat of the refrigerator 4 is utilized by the heating end 8 arranged on the right side of the refrigerator 4.

[0027] In this embodiment, a temperature and humidity sensor 12 is fixedly connected to the middle of the lower surface of the air duct 3 .

[0028] During specific use, the temperature and humidity inside the device can be monitored by setting the temperature and humidity sensor 12.

[0031] In this embodiment, a one-way valve 15 is fixedly connected to the bottom of the outer surface of the drain pipe 7 , and a filter plug 16 is fixedly connected to one end of the drain pipe 7 .

[0032] During specific use, the one-way valve 15 can be provided to prevent water in the drain pipe 7 from flowing back, and the filter plug 16 can filter external dust and impurities to prevent pipe blockage.

[0033] In this embodiment, a cover body 17 is fixedly connected to a side of the lower surface of the air duct 3 close to the exhaust fan 11 , and a hose 18 is fixedly connected to the lower surface of the cover body 17 .

[0037] In this embodiment, ventilation slots 21 are formed on both sides of the inner side surface of the housing 1 .

[0038] During specific use, the ventilation slots 21 are arranged so that the interior of the housing 1 can maintain a ventilated and heat-dissipating state, while reducing the entry of external dust.

[0039] In this embodiment, a motor 22 is fixedly connected to both sides of the inner side of the shell 1, a screw rod 23 is fixedly connected to the output end of the motor 22, a slider 24 is threadedly connected to the outer surface of the screw rod 23, and a baffle 25 is fixedly connected to the outer surface of the slider 24.

The ventilation groove 21 is opened when the equipment is ventilated, and the ventilation groove 21 is closed when the equipment is not ventilated.

[0041] Working principle: During use, the temperature and humidity sensor 12 monitors the temperature and humidity inside the equipment. When the temperature difference between the inside and outside of the shell 1 is about to reach the dew point, the anti-condensation mechanism is controlled to work, and the induced fan 2 draws the external air into the inside of the air duct 3 through the through hole 13. The dustproof screen 14 filters the external dust and impurities. The refrigerator 4 is turned on to reduce the temperature of the condensing plate 5. The external humid air encounters cold on the condensing plate 5 to produce condensation and cool down, thereby obtaining low-temperature dry air. The guide plate 6 guides the condensed water and discharges it to the outside through the drain pipe 7. The one-way valve 15 prevents the water in the drain pipe 7 from flowing back. The filter plug 16 filters the external dust and impurities to avoid pipe blockage. Under the action of the heating end 8 of the refrigerator 4, the low temperature The air is initially heated up, and the heater 9 heats the initially heated air to an appropriate temperature. Finally, the exhaust fan 11 acts to transport the dry air to the inside of the shell 1, which effectively improves the dryness of the air and can prevent the air temperature in the equipment from being too low to cause condensation, thereby playing a role in dehumidification and anti-condensation. The cover 17 guides and gathers the dry air exhausted by the exhaust fan 11, and a plurality of air holes 19 discharge the dry air inside the hose 18, so that the air discharge inside the shell 1 is more uniform. The motor 22 drives the screw rod 23 to rotate, so that the slider 24 drives the baffle 25 to move up and down, thereby opening and closing the ventilation slot 21. The ventilation slot 21 is opened when the equipment is ventilated, and the ventilation slot 21 is closed when the equipment is not ventilated.
