Technical Field
[0001] This utility model relates to the field of power plant electrical cabinet technology, specifically to an anti-condensation mechanism for power plant electrical cabinets in high humidity environments. Background Technology
[0002] Electrical cabinets in power plants are core devices used for the centralized control, distribution, and protection of electrical equipment in power generation, transmission, and distribution systems. They typically integrate components such as circuit breakers, relays, and transformers, possessing high protection levels and environmental adaptability. They are widely used in power plants for generator control, transmission line protection, distribution system management, and automated monitoring to ensure the safe and stable operation of the power system. In some power plants, electrical cabinets are exposed to high humidity environments for extended periods. Condensation can easily lead to short circuits and corrosion of internal components, severely impacting equipment lifespan and operational safety.
[0003] Chinese Patent (Authorization Announcement No.: CN217903709U, Authorization Announcement Date: 2022.11.25) proposes an anti-condensation device for electrical cabinets, belonging to the field of electrical cabinet technology. It addresses the problem that existing electrical cabinets are easily corroded by condensation, causing short circuits and affecting their service life. The device includes an electrical cabinet body, fixing slots, a cover, an anti-condensation mechanism, and anti-condensation plates. Two sets of fixing slots are provided, located on the upper left and right sides of the electrical cabinet body. The cover is rotatably connected to the front of the electrical cabinet body. The anti-condensation mechanism is fixedly connected inside the electrical cabinet body. The anti-condensation plates are also fixedly connected inside the electrical cabinet body, with both sets of anti-condensation plates tilted to the left and right sides respectively. This invention achieves the function of removing condensation from the electrical cabinet. Furthermore, the device has a simple structure, saves costs, and the collected condensation also provides heat dissipation for the electrical cabinet, effectively utilizing resources.
[0004] The aforementioned anti-condensation device for electrical cabinets relies on heating pipes to directly heat the air inside the cabinet for dehumidification. During dehumidification, the large amount of hot air generated by the heating pipes tends to accumulate inside the cabinet, conflicting with the heat dissipation requirements and causing a decrease in the heat dissipation efficiency of the electrical cabinet. This is especially true in scenarios where power plant equipment operates under high loads and requires continuous heat dissipation. On the other hand, the incoming air is not dried, and heating alone is insufficient to completely remove moisture from the air. The dehumidification effect is limited in high humidity environments. Therefore, we propose an anti-condensation mechanism for power plant electrical cabinets in high humidity environments. Utility Model Content
[0005] To address the shortcomings of existing technologies, this invention provides an anti-condensation mechanism for power plant electrical cabinets in high-humidity environments. It utilizes a molecular sieve within the drying cylinder of the air inlet assembly to dry and dehumidify the air entering the electrical cabinet, preventing the hot air generated by heating the dried air from affecting internal heat dissipation. The heating elements on the inner wall of the drying cylinder are used to restore the adsorption activity of the molecular sieve after it has been in operation for a period of time, ensuring that the molecular sieve can be reused to maintain a stable dehumidification effect. A quick-release mechanism facilitates maintenance and replacement of the molecular sieve, and the invention combines a humidity sensor and controller to achieve automatic dynamic adjustment of the dehumidification process, thus solving the problems mentioned earlier.

[0015] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0016] Please see Figure 1-6 This utility model provides a technical solution: a power plant electrical cabinet anti-condensation mechanism under high humidity environment, including an electrical cabinet 1, a cabinet door 2 is provided on the front side of the electrical cabinet 1, an air inlet component is installed on the right side of the electrical cabinet 1, an air outlet component is installed on the top of the electrical cabinet 1, and a water collection component is also provided on the top of the electrical cabinet 1. In a high-humidity environment, when the anti-condensation mechanism of the power plant's electrical cabinet is working, the cabinet door 2 on the front side of the electrical cabinet 1 is kept closed to ensure that the environment inside the cabinet is relatively sealed. Then, outside air enters the electrical cabinet 1 through the air intake component installed on the right side of the electrical cabinet 1, providing dry air to the cabinet. While the dry air entering the electrical cabinet 1 is flowing, the electrical cabinet 1 exhausts air outward through the air outlet component installed on its top, forming a complete air circulation process. Because the exhaust air has a high humidity, condensation may be generated on the top of the electrical cabinet 1 during the air outlet process. The condensation will be collected in time by the water collection component installed on the top of the electrical cabinet 1 to prevent condensation from adhering to the components inside the cabinet. Through the orderly coordination of "air intake - condensation collection - air outlet", the anti-condensation effect of the electrical cabinet 1 is achieved.
[0017] The air inlet assembly includes a drying cylinder 12, which is located in the middle of the right side of the electrical cabinet 1. An air inlet 13 is also provided on the right side of the electrical cabinet 1. A filter plate 3 is fixedly connected to the air inlet 13. An air outlet 17 and an air inlet 18 are provided at the top and bottom of the drying cylinder 12, respectively. The air inlet 18 and the air inlet 13 are fixedly connected by a pipe. A fan 14 is fixedly installed on the right side of the interior of the electrical cabinet 1. The input end of the fan 14 is fixedly connected to the air outlet 17 by a pipe. A filter cylinder 22 is slidably connected to the inner wall of the drying cylinder 12. A molecular sieve 23 is provided inside the filter cylinder 22. A quick-release mechanism is provided between the filter cylinder 22 and the drying cylinder 12. Heating elements 33 are also installed on the front and rear sides of the inner wall of the drying cylinder 12.
[0018] The quick-release mechanism includes a sealing cover 19, a fixing plate 20 fixedly connected to the middle left side of the sealing cover 19, a threaded groove 21 opened in the middle left side of the fixing plate 20, a sliding groove 26 opened at the right end of the drying cylinder 12, the sealing cover 19 being inserted into the sliding groove 26, the right end of the filter cylinder 22 being threadedly inserted into the threaded groove 21, and fixing blocks 1 24 fixedly connected to the front and rear sides of the fixing plate 20, both sets of fixing blocks 1 24 being slidably connected to the sliding groove 26, the top side of one set of fixing blocks 1 24 and the bottom side of the other set of fixing blocks 1 24 being fixedly connected to insert plates 25, the top and bottom left sides of the sliding groove 26 being fixedly connected to fixing blocks 27, the top of one set of fixing blocks 27 and the bottom of the other set of fixing blocks 27 being slotted 28, the two sets of insert plates 25 being slidably inserted into the two sets of slots 28 respectively, and the front and rear right sides of the sealing cover 19 being provided with pull grooves 29.
[0019] When the air intake assembly is working, outside air first enters through the air inlet 13 on the right side of the electrical cabinet 1. The filter plate 3 fixed on the air inlet 13 performs preliminary filtration of the air. The filtered air is then connected to the air inlet 18 at the bottom of the drying cylinder 12 through a pipe, and then enters the drying cylinder 12 located in the middle of the right side of the electrical cabinet 1. The filter cylinder 22, which is slidably connected to the inner wall of the drying cylinder 12, is equipped with a molecular sieve 23. When the air flows through the filter cylinder 22, the molecular sieve 23 adsorbs and dehumidifies the water vapor in the air. The dehumidified air is then drawn into the electrical cabinet 1 through the air outlet 17 at the top of the drying cylinder 12 by the fan 14 fixedly installed on the right side of the electrical cabinet 1, providing dry air for the cabinet. After the molecular sieve 23 has been working for a period of time, the heating plates 33 installed on the front and rear sides of the inner wall of the drying cylinder 12 are activated to heat the molecular sieve 23 to restore its moisture content. To restore its adsorption activity, when the filter 22 or molecular sieve 23 needs maintenance or replacement, the sealing cover 19 is operated through the pull groove 29 on the front and rear sides of the right side. This allows the two sets of fixing blocks 24 fixed on the front and rear sides of the fixing plate 20 to slide in the slide groove 26 opened at the right end of the drying cylinder 12. This causes the insert plates 25 on the top side of one set of fixing blocks 24 and the bottom side of the other set of fixing blocks 24 to slide out from the slots 28 opened on the top and bottom fixing blocks 27 on the left side of the slide groove 26. Since the right end of the filter 22 is threaded into the threaded groove 21 in the middle of the left side of the fixing plate 20, and the sealing cover 19 is inserted into the slide groove 26, the sealing cover 19, the fixing plate 20, and the filter 22 can be taken out together for maintenance. After maintenance, the operation is reversed so that the insert plate 25 is reinserted into the slot 28 and the sealing cover 19 is reinserted into the slide groove 26, completing the assembly.
[0020] The air outlet assembly includes an exhaust fan 7, which is fixedly installed on the top side inside the electrical cabinet 1. An air outlet 4 is provided on the top side of the electrical cabinet 1 directly above the exhaust fan 7. A solenoid valve 5 is installed on the top right side of the electrical cabinet 1, and the input end of the solenoid valve 5 is fixedly connected to the air outlet 4 through a pipe.
[0021] When the air outlet assembly is working, the exhaust fan 7, which is fixedly installed on the top side inside the electrical cabinet 1, starts and guides the air inside the electrical cabinet 1 upward. Since an air outlet 4 is opened through the top side of the electrical cabinet 1 directly above the exhaust fan 7, the guided air can be discharged to the outside of the electrical cabinet 1 through the air outlet 4. At the same time, the solenoid valve 5 installed on the top right side of the electrical cabinet 1 is fixedly connected to the air outlet 4 through a pipe. The solenoid valve 5 can control the air discharge path at the air outlet 4 according to actual needs, thereby regulating the air discharge process inside the electrical cabinet 1.
[0022] The water collection assembly includes an A-shaped diversion plate 8, which is fixedly connected to the top side of the electrical cabinet 1. The A-shaped diversion plate 8 is located directly below the exhaust fan 7 and has a ventilation hole 10. A collection trough 9 is fixedly connected to the inner wall of the top side of the electrical cabinet 1. The bottom left and right ends of the A-shaped diversion plate 8 are respectively located on the top left and right sides of the collection trough 9. A water outlet 15 is opened on the rear side of the collection trough 9. A water outlet pipe 16 is fixedly connected to the bottom end of the water outlet 15. A U-shaped pipe 31 is fixedly connected to the bottom end of the water outlet pipe 16. A drain outlet 32 is opened at the bottom rear side of the electrical cabinet 1. The drain outlet 32 and the U-shaped pipe 31 are fixedly connected by a pipe.
[0023] When the water collection assembly is working, the A-shaped diversion plate 8, which is fixedly connected to the top side inside the electrical cabinet 1, is used to collect the condensation generated inside the electrical cabinet 1. Since the A-shaped diversion plate 8 has a ventilation hole 10 directly below the exhaust fan 7, it can avoid obstructing the airflow guided by the exhaust fan 7. The left and right ends of the bottom of the A-shaped diversion plate 8 are respectively attached to the top left and right sides of the collection tank 9, which is fixedly connected to the inner wall of the top side of the electrical cabinet 1, so that the condensation collected on the A-shaped diversion plate 8 can flow into the collection tank 9 along its inclined structure. The water outlet 15 opened on the rear side of the collection tank 9 and the water outlet pipe 16 fixedly connected to the bottom end form a drainage path. The condensation collected in the collection tank 9 enters the water outlet pipe 16 through the water outlet 15. The bottom end of the water outlet pipe 16 is fixedly connected to the U-shaped pipe 31. The condensation further flows into the U-shaped pipe 31. The U-shaped pipe 31 achieves water sealing, and then through the drain outlet 32 at the bottom rear side of the electrical cabinet 1, which is connected to the U-shaped pipe 31, it is finally discharged to the outside of the electrical cabinet 1.
[0024] The right side of the sealing cover 19 is provided with a switch rotation direction indicator 30. When the filter 22 or molecular sieve 23 needs to be maintained and the sealing cover 19 needs to be operated, the switch rotation direction indicator 30 on the right side of the sealing cover 19 can intuitively indicate the correct opening and closing rotation direction of the sealing cover 19.
[0025] A humidity sensor 6 is installed on the left side inside the electrical cabinet 1, and a controller 11 is installed on the rear side inside the electrical cabinet 1. The humidity sensor 6 continuously monitors the humidity data inside the electrical cabinet 1 and transmits the monitored humidity information to the controller 11 installed on the rear side inside the electrical cabinet 1 in real time. After receiving the information transmitted by the humidity sensor 6, the controller 11 can adjust the operating status of the anti-condensation related components of the electrical cabinet 1 (such as the fan 14 and heating element 33 of the air inlet assembly, and the exhaust fan 7 and solenoid valve 5 of the air outlet assembly) based on the humidity data, so that the anti-condensation mechanism can be started or its working intensity adjusted as needed, ensuring that the humidity inside the electrical cabinet 1 is maintained within a reasonable range.
[0026] Working principle: In a high humidity environment, when the anti-condensation mechanism of the electrical cabinet of the power plant is working, the cabinet door 2 on the front side of the electrical cabinet 1 is kept closed to ensure that the environment inside the cabinet is relatively sealed. Then, the outside air first enters through the air inlet 13 on the right side of the electrical cabinet 1. The filter plate 3 fixed on the air inlet 13 performs preliminary filtration of the air. The filtered air is connected to the air inlet 18 at the bottom of the drying cylinder 12 through the pipe, and then enters the drying cylinder 12 located in the middle of the right side of the electrical cabinet 1. The filter cylinder 22 slidably connected to the inner wall of the drying cylinder 12 is equipped with a molecular sieve 23. When the air flows through the filter cylinder 22, the molecular sieve 23 adsorbs and dehumidifies the water vapor in the air. The dehumidified air is drawn into the electrical cabinet 1 through the air outlet 17 at the top of the drying cylinder 12 by the fan 14 fixedly installed on the right side of the electrical cabinet 1, providing dry air for the cabinet. As the dry air flows into the electrical cabinet 1, the exhaust fan 7, which is fixedly installed on the top side of the electrical cabinet 1, starts and guides the air inside the electrical cabinet 1 upward. Since the exhaust fan 7 is directly above the exhaust fan 7, the air guided by the exhaust fan 7 can be discharged to the outside of the electrical cabinet 1 through the exhaust fan 7, forming a complete air circulation process. At the same time, the solenoid valve 5 installed on the top right side of the electrical cabinet 1 is fixedly connected to the exhaust fan 4 through a pipe. The solenoid valve 5 can control the air discharge path at the exhaust fan 4 according to actual needs. Because the exhaust air has high humidity, condensation may form on the top of the electrical cabinet 1 during the exhaust process. The A-shaped deflector plate 8, fixedly connected to the top side inside the electrical cabinet 1, collects this condensation. Since the A-shaped deflector plate 8 has a ventilation hole 10 directly below the exhaust fan 7, it avoids obstructing the airflow guided by the exhaust fan 7. The bottom left and right ends of the A-shaped deflector plate 8 are respectively positioned on the top left and right sides of the collection trough 9 fixedly connected to the inner wall of the top side of the electrical cabinet 1, allowing the condensation collected on the A-shaped deflector plate 8 to flow into the collection trough 9 along its inclined structure. The outlet 15 on the rear side of the collection tank 9 forms a drainage passage with the outlet pipe 16 fixedly connected to the bottom. The condensate collected in the collection tank 9 enters the outlet pipe 16 through the outlet 15. The bottom end of the outlet pipe 16 is fixedly connected to the U-shaped pipe 31. The condensate further flows into the U-shaped pipe 31, which achieves a water seal. Then, through the drain outlet 32 at the bottom of the rear side of the electrical cabinet 1, which is connected to the U-shaped pipe 31, the condensate is finally discharged to the outside of the electrical cabinet 1, thus preventing condensation from adhering to the components inside the cabinet. Through the orderly coordination of "air intake - condensate collection - air exhaust", the anti-condensation effect of the electrical cabinet 1 is achieved. After the molecular sieve 23 has been working for a period of time, the heating plates 33 installed on the front and rear sides of the inner wall of the drying cylinder 12 are activated to heat the molecular sieve 23 and restore its adsorption activity. When maintenance or replacement of the filter cylinder 22 or the molecular sieve 23 is required, the sealing cover 19 is operated through the slot 29 on the front and rear sides of the right side of the sealing cover 19. This causes the two sets of fixing blocks 24 fixed on the front and rear sides of the fixing plate 20 to slide in the sliding groove 26 opened at the right end of the drying cylinder 12, thereby driving the top side of one set of fixing blocks 24 and the other set of fixing blocks 24 to move. The insert plate 25 on the bottom side of the fixed block 24 slides out from the slots 28 opened on the top and bottom of the fixed block 27 on the left side of the slide groove 26. Since the right end of the filter tube 22 is threaded into the threaded groove 21 in the middle of the left side of the fixed plate 20, and the sealing cover 19 is inserted into the slide groove 26, the sealing cover 19, the fixed plate 20 and the filter tube 22 can be taken out together for maintenance. After maintenance, the operation is reversed so that the insert plate 25 is reinserted into the slot 28 and the sealing cover 19 is inserted back into the slide groove 26 to complete the assembly.
