Description

Technical Field

[0001] This invention relates to the field of high-voltage equipment, specifically a high-voltage equipment foundation condensation prevention and control system and its control method based on dual-dimensional humidity monitoring and intelligent linkage ventilation. Background Technology

[0002] In power systems, the foundations of high-voltage equipment (such as transformers, high-voltage switchgear, and cable joints) (e.g., equipment bases, embedded cabinets, terminal blocks) are often exposed to outdoor or semi-outdoor environments with fluctuating humidity and high levels of dust and impurities, making them highly susceptible to condensation due to moisture in the air. This condensation adheres to the metal components and insulation structures of the high-voltage equipment foundations, significantly reducing the equipment's insulation performance and leading to serious faults such as leakage, short circuits, and even equipment burnout. This directly impacts the safe and stable operation of the power system. Therefore, condensation control on high-voltage equipment foundations is one of the core requirements for power equipment operation and maintenance.

[0003] Currently, the industry's main technology for condensation control on high-voltage equipment foundations adopts a "single parameter monitoring + fixed mode execution" approach. Specifically, this involves installing a single temperature and humidity sensor inside the equipment foundation protection box to monitor the relative humidity and temperature of the air inside the box. When the relative humidity reaches a preset threshold (such as RH 85%), the ventilation fan is triggered or the heating element is activated to achieve dehumidification or humidity reduction. Some technologies are supplemented with passive moisture-proofing methods such as desiccants to further control the humidity inside the box.

[0004] However, existing technologies suffer from a critical flaw: insufficient precision in core prevention and control. Current technologies rely solely on temperature and humidity sensors to monitor only the single-dimensional parameter of "relative humidity." Relative humidity is significantly affected by ambient temperature and cannot accurately reflect the actual water vapor content (i.e., absolute water content) in the air. Specifically, in low-temperature environments (such as early winter mornings when the temperature inside the equipment enclosure drops below 5°C), even if the actual water vapor concentration inside the enclosure is low, the measured relative humidity can easily rise to the condensation threshold due to the temperature drop. This causes the existing system to misjudge a "condensation risk state," triggering heating and high-speed ventilation measures, resulting in unnecessary energy waste. Conversely, in high-temperature environments (such as summer afternoons when the temperature inside the enclosure rises above 35°C) and when the equipment heats up briefly, the temperature inside the enclosure increases, and the measured relative humidity drops to a safe range. However, the actual water vapor concentration inside the enclosure does not decrease at this time. The existing system may misjudge this as "no condensation risk," stopping or failing to activate prevention and control measures. When the temperature drops, the high concentration of water vapor rapidly condenses, causing damage to the equipment insulation and creating safety hazards.

[0005] This "misjudgment and miscontrol" or "missed judgment and missed control" caused by "the inability of a single monitoring dimension to match the actual water vapor state" is a core pain point that existing basic condensation prevention and control technologies for high-voltage equipment cannot solve. It seriously restricts the prevention and control effect and energy utilization efficiency, and cannot meet the needs of long-term stable operation of high-voltage equipment. Summary of the Invention

[0006] This invention provides a high-pressure equipment foundation condensation prevention and control system and its control method based on dual-dimensional humidity monitoring and intelligent linkage ventilation, in order to solve the problem of misjudgment, miscontrol, or missed judgment and control of condensation risk caused by relying on a single temperature and humidity sensor to monitor relative humidity, which is easily affected by temperature and cannot truly reflect the actual water vapor content.

[0007] To achieve the above objectives, the technical solution adopted by the present invention is as follows: A high-pressure equipment foundation condensation control system based on dual-dimensional humidity monitoring and intelligent linkage ventilation includes: The main housing (1) is used to house the foundation of the high-voltage equipment. The dual-modal humidity monitoring unit (3) includes an intelligent decision-making central module (35), a temperature and humidity detector (310), and a gas moisture detector (311). The temperature and humidity detector (310) acquires the temperature and humidity data of the air inside the main housing (1), and the gas moisture detector (311) acquires the water vapor concentration data of the air inside the main housing (1). The temperature and humidity detector (310) and the gas moisture detector (311) are electrically connected to the intelligent decision-making central module (35) respectively. The dynamic ventilation assembly (4) includes a centrifugal fan (43); when the centrifugal fan (43) is working, it draws the air in the main housing (1) to the outside of the main housing (1), and the intelligent decision-making central module (35) is electrically connected to the centrifugal fan (43); The active condensation suppression device (5) includes an installation chamber (51), a convection fan (52), a heat pipe (57), and an electric heating wire (56). The installation chamber (51) is divided into a convection chamber and a heating chamber. The convection fan (52) is located in the convection chamber. When the convection fan (52) is working, it causes the air outside the installation chamber (51) to convect in the convection chamber. The heat pipe (57) and the electric heating wire (56) are respectively located in the heating chamber. One end of the heat pipe (57) is connected to the convection chamber and the other end is connected to the main housing (1). When the electric heating wire (56) is working, it heats the heat pipe (57). The intelligent decision-making central module (35) is electrically connected to the convection fan (52) and the electric heating wire (56) respectively.

[0008] Furthermore, the dual-modal humidity monitoring unit (3) also includes a sensor integration box (31), which is connected to the main housing (1). A fan (38) is provided inside the sensor integration box (31), and the temperature and humidity detector (310) and the gas moisture detector (311) are both located inside the sensor integration box (31). When the fan (38) is working, it draws the air in the main housing (1) into the sensor integration box (31).

[0009] Furthermore, the temperature and humidity detector (310) is wrapped with a highly absorbent sponge layer (39).

[0010] Furthermore, a window opening is provided on one side of the main housing (1), and an electrically controlled ventilation window (6) is installed in the window opening; the centrifugal fan (43) in the dynamic ventilation assembly (4) is installed on the main housing (1) at a position corresponding to the window opening; the intelligent decision-making central module (35) is electrically connected to the electrically controlled ventilation window (6).

[0011] Furthermore, the convection chamber inside the installation compartment (51) of the active condensation suppression device (5) is separated into an independent space by a filter device, the convection fan (52) is located outside the independent space, and one end of the heat pipe (57) is connected to the independent space.

[0012] Furthermore, the electric heating wire (56) is wound around the heat-conducting tube (57).

[0013] Furthermore, the main housing (1) is divided into upper and lower chambers by a partition. The high-pressure equipment foundation is located in the upper chamber, and the partition is provided with ventilation holes that connect the upper and lower chambers. A filter screen is provided in the ventilation holes. The other end of the heat pipe (57) is connected to the lower chamber of the main housing (1).

[0014] A control method for the above-mentioned high-pressure equipment foundation condensation prevention and control system based on dual-dimensional humidity monitoring and intelligent linkage ventilation is as follows: The intelligent decision-making central module (35) receives temperature and humidity data (including relative humidity RH and ambient temperature T of the air inside the main chamber (1)) acquired by the temperature and humidity detector (310), and water vapor concentration data C (unit: g / m³) of the air inside the main chamber (1) acquired by the gas moisture detector (311). 3 ); The intelligent decision-making central module (35) compares and analyzes these two humidity data to determine the system's state and issues corresponding control commands. The specific comparison and judgment process is as follows: Set exclusive thresholds for different types of physical quantities, and preset auxiliary verification thresholds to improve the accuracy of judgment: ① Relative humidity exclusive thresholds: condensation warning threshold RH1 and condensation critical threshold RH2. These two thresholds are set according to the common condensation risk humidity range in the high-voltage equipment operating environment; ② Water vapor concentration exclusive thresholds: condensation warning threshold C1 and condensation critical threshold C2. These are set with reference to the safety standards for water vapor content in the high-voltage equipment moisture-proof design specifications; ③ Auxiliary verification thresholds: the difference thresholds ΔT1 and ΔT2 between ambient temperature T and real-time dew point temperature T_d. The dew point temperature T_d is calculated by the intelligent decision center module (35) based on "relative humidity RH + ambient temperature T" through the built-in dew point algorithm (the dew point temperature is the core standard for judging whether condensation will occur. When the air temperature drops to T_d, condensation will occur). The level of condensation risk can be further verified through the temperature difference. Layered comparison to determine system status: Normal state judgment: If the relative humidity RH does not exceed RH1, the water vapor concentration C does not exceed C1, and the difference between the ambient temperature T and the dew point temperature T_d is greater than ΔT1, it means that the air humidity inside the main box is low and the conditions for condensation are far away. Therefore, it is judged as a normal state, and the intelligent decision center module (35) issues an instruction to start basic ventilation. Condensation warning status judgment: If any of the following conditions are met, it means that the humidity inside the main box is close to the risk range, but has not yet reached the point where condensation will occur immediately. Therefore, it is judged as a condensation warning status, and the intelligent decision center module (35) issues an instruction to start enhanced ventilation: ① The relative humidity RH exceeds RH1 but is less than RH2, the water vapor concentration C does not exceed C1, and the difference between T and T_d is greater than ΔT2; ② The water vapor concentration C exceeds C1 but is less than C2, the relative humidity RH does not exceed RH1, and the difference between T and T_d is greater than ΔT2; ③ The relative humidity RH exceeds RH1 and the water vapor concentration C exceeds C1, but the difference between T and T_d is greater than ΔT1. Condensation risk status judgment: If any of the following conditions are met, it means that the interior of the main box is close to or has reached the conditions for condensation to form, and there is a clear risk of condensation. Therefore, it is judged as a condensation risk status. The intelligent decision center module (35) issues an instruction to start ventilation and heating dual suppression measures: ① The relative humidity RH reaches or exceeds RH2 (at this time, the air is close to saturation and is very easy to condense); ② The water vapor concentration C reaches or exceeds C2 (at this time, the water vapor content in the air is too high and the probability of condensation is extremely high); ③ The difference between the ambient temperature T and the dew point temperature T_d is less than or equal to ΔT2 (at this time, the air temperature is close to the dew point and condensation will occur soon); When the intelligent decision center module (35) determines that the state is normal, the intelligent decision center module (35) controls the electric ventilation window (6) to open and controls the centrifugal fan (43) in the dynamic ventilation assembly (4) to run at low speed to draw the air in the main box (1) to the outside of the main box (1) to achieve natural ventilation of the main box (1) to the outside. When the intelligent decision-making central module (35) determines that the condensation warning state is in effect, the intelligent decision-making central module (35) controls the ventilation window (6) to open, the centrifugal fan (43) in the dynamic ventilation assembly (4) to run at medium speed, and controls the convection fan (52) in the active condensation suppression device (5) to work at full load. When the convection fan (52) is working, it draws the air outside the installation chamber (51) into the convection chamber, which increases the air pressure in the convection chamber, thereby generating a pressure difference at both ends of the heat pipe (57), and then the air in the convection chamber enters the main box (1) through the heat pipe (57). With the medium speed operation of the centrifugal fan (43), the air in the main box (1) is replaced and the ventilation of the main box (1) to the outside is accelerated. When the intelligent decision-making central module (35) determines that there is a risk of condensation, the intelligent decision-making central module (35) opens the electrically controlled ventilation window (6), the centrifugal fan (43) in the dynamic ventilation assembly (4) runs at high speed, the convection fan (52) in the active condensation suppression device (5) works at full load, and controls the electric heating wire (56) to heat the air passing through the heat pipe (57), so that the air in the convection chamber is heated and enters the main box (1), thereby raising the temperature of the air in the main box (1), and then causing the moisture that may condense in the main box (1) to form water vapor and be drawn out to the outside of the main box (1) by the centrifugal fan (43).

[0015] Furthermore, the intelligent decision-making central module (35) compares the time in which the condensation risk state is in comparison with a preset time threshold. If the time in which the condensation risk state is in comparison with the preset time threshold, the intelligent decision-making central module (35) generates an alarm signal.

[0016] Compared with the prior art, the beneficial effects of the present invention are as follows: This invention employs a dual-modal design of "active air extraction + dual-parameter synchronous detection." On one hand, the fan of the dual-modal humidity monitoring unit ensures a stable flow of air into the sensor integration box from the main chamber, avoiding detection deviations caused by local airflow interference. On the other hand, it simultaneously collects temperature, humidity, and water vapor concentration data, forming a dual-dimensional detection system that effectively eliminates the limitations of single-parameter detection. Furthermore, the pre-treatment design of the highly absorbent sponge layer adsorbs trace amounts of condensed liquid water that may come into contact with the temperature and humidity sensors in the sealed environment of high-pressure equipment, preventing sensor distortion. Combined with the active air extraction design, it does not alter the true humidity of the air, ensuring continuous and stable detection data, thereby further stabilizing the detection environment. Combined with a high-frequency monitoring frequency of 1 time per minute, compared to the low-frequency passive detection of existing technologies, it achieves accurate capture and real-time feedback of humidity status, providing reliable data support for subsequent control and significantly reducing the condensation misjudgment rate.

[0017] This invention saves energy by using low-speed ventilation under normal conditions, enhances air exchange efficiency under warning conditions, and rapidly dehumidifies by combining heating with high-speed ventilation under risk conditions, achieving precise adaptation to different humidity scenarios. After the state returns to normal and stabilizes for 5 minutes within a set time, it automatically resumes low-load operation. If the state remains in a condensation risk state for an extended period without returning to normal, an alarm will be triggered in time. Furthermore, the system can switch to the warning state in advance via platform commands to achieve preventative control. Compared to the "one-size-fits-all" control of existing technologies, this invention reduces energy consumption by more than 30% while ensuring protective effects, and improves the response speed to the minute level, effectively avoiding the risk of condensation formation.

[0020] To enable those skilled in the art to better understand the present invention, the embodiments will be described in detail below with reference to the accompanying drawings and examples. This will allow for a full understanding of how the present invention uses technical means to solve technical problems and achieve corresponding technical effects, and to facilitate its implementation. The embodiments of the present invention and the various features within them can be combined with each other without conflict, and all resulting technical solutions are within the protection scope of the present invention.

[0021] Obviously, the described embodiments are only some, not all, of the embodiments of the present invention. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without inventive effort should fall within the scope of protection of the present invention.

[0022] It should be noted that the terms "comprising" and "having" and any variations thereof in the specification, claims, and accompanying drawings of this invention are intended to cover non-exclusive inclusion.

[0023] like Figures 1-6 As shown, this embodiment discloses a high-pressure equipment basic condensation control system based on dual-dimensional humidity monitoring and intelligent linkage ventilation. It includes a main housing 1 for providing a closed protective space, a dual-modal humidity monitoring unit 3 for dual-dimensional humidity detection, a condensation active suppression device 5 for actively suppressing condensation, a dynamic ventilation assembly 4 for realizing outward ventilation from the main housing 1, and an electrically controlled ventilation window 6 for adjusting the sealing and ventilation states.

[0024] like Figure 1 , Figure 2As shown, active condensation suppression devices 5 are installed on both outer walls of the main housing 1, and a window opening is provided in the middle of the top of the main housing 1. An exhaust duct 11 for guiding air out is installed on the top surface of the main housing 1. The bottom opening of the exhaust duct 11 connects to the interior of the main housing 1 through the window opening. A waterproof cover 12 to prevent rainwater infiltration is fixedly installed at the top opening of the exhaust duct 11. Inclined exhaust pipes 13 for dispersing exhaust are connected to the four side walls of the exhaust duct 11. An electrically controlled ventilation window 6 is installed in the window opening at the top of the main housing 1, and a dynamic ventilation assembly 4 is installed inside the exhaust duct 11.

[0025] The main housing 1 is divided into upper and lower chambers by a horizontal partition. A base 2 is located in the lower chamber, with its top supporting the middle portion of the partition and its bottom fixed to the bottom of the main housing 1. Ventilation holes are located on both sides of the partition extending beyond the base 2, connecting the upper and lower chambers. HEPA particulate filters 21 are installed within these ventilation holes to filter impurities. The high-voltage equipment foundation is placed in the upper chamber of the main housing 1, specifically within the partition portion supported by the base 2.

[0026] like Figure 4 As shown, a dual-mode humidity monitoring unit 3 is fixedly installed near the top of the upper chamber of the main housing 1. The dual-mode humidity monitoring unit 3 includes a sensor integration box 31. The top of the sensor integration box 31 is fixedly connected to the inner wall of the top of the main housing 1 via a mounting bracket 32. An air intake 33 for drawing air from the box is installed at the bottom of the sensor integration box 31. Specifically, the lower end of the air intake 33 is connected to the interior of the main housing 1, and the upper end of the air intake 33 is located at the bottom of the sensor integration box 31 and is connected to the interior of the sensor integration box 31.

[0027] The sensor integration box 31 contains a stabilizing bracket 34, which covers the upper end of the air intake 33 at the connection point at the bottom of the sensor integration box 31. An intelligent decision-making central module 35 for analyzing data and issuing commands is mounted on the top of the stabilizing bracket 34. The intelligent decision-making central module 35 includes a controller and a power supply. The controller of the intelligent decision-making central module 35 is electrically connected to a wireless data interaction terminal 36 for transmitting data and issuing warnings.

[0028] A low-noise motor 37 is installed in the upper part of the stable bracket 34. The output shaft of the low-noise motor 37 is vertically downward, and a fan blade is fixedly connected to the lower end of the output shaft of the low-noise motor 37. The low-noise motor 37 and the fan blade constitute a fan 38. The controller of the intelligent decision-making central module 35 is electrically connected to the low-noise motor 37 in the fan 38 (the fan 38 is used to actively draw air from the main housing and form a stable airflow in the bracket). The stable bracket 34 has a hollow mounting base (with a mesh structure to ensure smooth airflow) in the middle. A breathable and insulating protective sleeve is embedded in the hollow mounting base. A temperature and humidity detector 310 for detecting temperature and humidity is fixed in the breathable and insulating protective sleeve. The temperature and humidity detector 310 is electrically connected to the controller of the intelligent decision-making central module 35. The breathable and insulating protective sleeve can avoid external interference and eliminate the risk of leakage, while not obstructing the contact between air and the sensor. A gas moisture detector 311 for detecting water vapor concentration is installed in the lower part of the stable bracket 34. The gas moisture detector 311 is also electrically connected to the controller of the intelligent decision-making central module 35. The smooth airflow driven by the fan realizes dual-dimensional synchronous monitoring.

[0029] The core function of the super absorbent sponge layer 39 is to adapt to condensation prevention scenarios in high-pressure equipment, ensure the detection stability of temperature and humidity detectors, extend their service life, and improve the system's accuracy in predicting condensation risks, as detailed below: The sponge is porous and breathable, allowing air to pass through smoothly and contact the sensor probe without blocking gaseous water molecules. It only absorbs tiny condensation droplets formed on the sensor surface due to temperature differences, as well as mist droplets from the air; it does not adsorb water vapor molecules from the air. Since humidity meters measure the concentration of gaseous water molecules, this prevents the measured value from being too high, ensuring the reading matches the actual air humidity.

[0030] The key to capturing the critical state of condensation and providing early warnings for high-voltage equipment is to "initiate measures before condensation occurs." Without a sponge, tiny water droplets appearing on the sensor surface can cause sudden changes in humidity readings, making it impossible for the system to determine the true humidity trend. With a sponge, these water droplets are quickly absorbed, allowing the sensor to stably display the critical humidity range of "rapid condensation." By combining this data with that of another detector, the system can activate ventilation or heating devices in advance to prevent condensation from corroding the equipment.

[0031] Protecting sensors ensures durability and accuracy. High-voltage equipment enclosures are often placed in damp and dusty environments. Sponges can act as a "protective layer": on the one hand, they absorb condensation, preventing water droplets from directly soaking the sensor and causing short circuits and corrosion; on the other hand, they block dust, metal shavings, and other impurities, preventing the sensor's vents from being blocked and ensuring long-term detection accuracy and response speed.

[0032] like Figure 3As shown, the active condensation suppression device 5 includes a T-shaped mounting chamber 51, wherein the horizontal part of the T-shaped mounting chamber 51 and the vertical part of the T-shaped mounting chamber 51 are separated from each other, with the horizontal part of the T-shaped mounting chamber 51 serving as a convection chamber and the vertical part of the T-shaped mounting chamber 51 serving as a heating chamber.

[0033] The installation compartment 51 is fixed to the corresponding side of the main housing 1. Fans are installed on the two symmetrical sides of the convection chamber of the installation compartment 51 to form convection fans 52 for forcibly introducing external air. The controller of the intelligent decision-making central module 35 is electrically connected to the convection fans 52. The convection chamber is equipped with two layers of PTFE high-efficiency filter plates 53 for high-efficiency filtration. Strip-shaped sliders are fixedly connected to the upper and lower surfaces of the PTFE high-efficiency filter plates 53. The upper and lower end surfaces of the installation compartment 51 are respectively provided with grooved slide rails that match the sliders. The filter plates are precisely installed by the sliders being embedded in the slide rails. The mating surfaces of the sliders and slide rails, as well as the edges of the PTFE high-efficiency filter plates 53, are all wrapped with sealing strips to achieve a sealed installation. The PTFE high-efficiency filter plates 53 are filled with polyester fiber layers 54 to enhance the filtration effect. Through the sealed assembly structure, the two layers of PTFE high-efficiency filter plates 53 are tightly fitted with the side wall of the convection chamber to form an independent and sealed filtration space. An air guide tube is provided at the bottom center of the convection chamber to guide air. The upper end of the air guide tube is located at the bottom of the convection chamber and communicates with the convection chamber. The lower end of the air guide tube leads into the heating chamber.

[0034] One side of the heating chamber of the installation compartment 51 is provided with an installation port, in which a quick-release mounting plate 55 is detachably installed. An electric heating wire 56 for heating and dehumidification is connected to the inner side of the quick-release mounting plate 55 facing the heating chamber. The controller of the intelligent decision-making central module 35 is electrically connected to the electric heating wire 56. A heat-conducting pipe 57 is provided inside the heating chamber, and the electric heating wire 56 is wound around the outside of the heat-conducting pipe 57. The lower end of the heat-conducting pipe 57 is connected to the lower cavity of the main housing 1, and the upper end of the heat-conducting pipe 57 is threadedly connected to an air guide cylinder that enters the heating chamber via an external nut 58. A glass wool insulation layer 59 is also fixed around the inner wall of the heating chamber of the installation compartment 51 to reduce heat loss.

[0035] like Figure 6 As shown, the dynamic ventilation assembly 4 is located inside the exhaust air guide channel 11. The dynamic ventilation assembly 4 includes a silicone flexible support 41 with buffering characteristics. The upper end of the silicone flexible support 41 is fixedly connected to the bottom of the leak-proof top cover 12. A micro motor 42 is installed in the silicone flexible support 41. The output shaft of the micro motor 42 points vertically downward to the window at the top of the main housing 1. A centrifugal fan blade for accelerating exhaust is installed at the lower end of the output shaft of the micro motor 42. The micro motor 42 and the centrifugal fan blade form a centrifugal fan 43. The centrifugal fan blade of the centrifugal fan 43 extends into the upper layer of the window at the top of the main housing 1. The controller of the intelligent decision center module 35 is electrically connected to the micro motor 42 in the centrifugal fan 43.

[0036] like Figure 5 As shown, the electrically controlled ventilation window 6 includes a frame 61 fixed to the inner wall of the top of the main housing 1. The frame 61 surrounds the window at the top of the main housing 1. Several rotating rods 62 are arranged inside the frame 61. Each rotating rod 62 has a rubber sealing baffle 63 (with rounded chamfered edges to prevent jamming) installed on both sides for adjusting the seal. One end of each rotating rod 62 passes through one side of the frame 61 and is coaxially fixedly connected to a follower gear 64. The other end of each rotating rod 62 is rotatably connected to the other side of the frame 61. A miniature air pump 66 is provided outside the frame 61. The miniature air pump 66 is fixed to the inner wall of the top of the main housing 1. The output end of the miniature air pump 66 is fixedly connected to a rack 65 for driving the gears. The rack 65 and each follower gear 64 are engaged in transmission to realize the opening and closing control of the rubber sealing baffle 63. The controller of the intelligent decision-making central module 35 is electrically connected to the solenoid valve of the air circuit of the miniature air pump 66.

[0037] This embodiment also discloses the control method of the above-mentioned high-pressure equipment foundation condensation prevention and control system based on dual-dimensional humidity monitoring and intelligent linkage ventilation, including the following specific steps: Step S1: The external monitoring platform presets core parameters to the controller of the intelligent decision-making central module 35 via the wireless data interaction terminal 36. These parameters include: ① Specific thresholds: relative humidity condensation warning threshold RH1, condensation critical threshold RH2; water vapor concentration condensation warning threshold C1, condensation critical threshold C2; ② Auxiliary verification thresholds: thresholds ΔT1 and ΔT2 representing the difference between ambient temperature T and dew point temperature T_d; ③ Other parameters: monitoring frequency 1 time / minute, preset time threshold for condensation risk status (e.g., 10 minutes). All parameters are stored in the controller of the intelligent decision-making central module 35. Simultaneously, the controller incorporates a dew point algorithm, serving as the core basis for subsequent data processing and status determination.

[0038] In step S2, the controller of the intelligent decision-making central module 35 drives the low-noise motor 37 in the dual-modal humidity monitoring unit 3 to drive the fan 38 to work, drawing air from the main housing 1 through the air inlet 33 to the sensor integration box 31; the temperature and humidity detector 310 (embedded in the breathable insulating protective sleeve of the hollow mounting base to avoid leakage and data interference) detects the temperature and humidity data of the air, and the gas moisture detector 311 detects the water vapor concentration data of the air. The temperature and humidity data and water vapor concentration data are transmitted to the controller of the intelligent decision-making central module 35.

[0039] Step S3: The controller of the intelligent decision-making central module 35 has a built-in comparative analysis program. It first integrates and processes the collected temperature, humidity, and water vapor concentration data, and then calculates the current dew point temperature T_d based on "relative humidity + ambient temperature" using a built-in algorithm. After that, it combines the previously preset exclusive threshold and auxiliary verification threshold, and performs a step-by-step layered comparative analysis to determine the system's state and issue the corresponding control command. The specific judgment criteria are as follows: If the conditions are met that "relative humidity does not exceed the warning threshold RH1, water vapor concentration does not exceed the warning threshold C1, and the difference between ambient temperature and dew point temperature is greater than ΔT1", it is judged as "normal state" and a basic ventilation command is issued. If any of the following conditions are met, the system is considered to be in a "condensation warning state" and an enhanced ventilation command is issued: ① The relative humidity exceeds the warning threshold RH1 but does not reach the critical threshold RH2, the water vapor concentration does not exceed the warning threshold C1, and the difference between the ambient temperature and the dew point temperature is greater than ΔT2; ② The water vapor concentration exceeds the warning threshold C1 but does not reach the critical threshold C2, the relative humidity does not exceed the warning threshold RH1, and the difference between the ambient temperature and the dew point temperature is greater than ΔT2; ③ Both the relative humidity and the water vapor concentration exceed their respective warning thresholds, but the difference between the ambient temperature and the dew point temperature is greater than ΔT1. If any of the following conditions are met, the system is judged to be in a "condensation risk state" and a command for dual suppression of ventilation and heating is issued: ① The relative humidity reaches or exceeds the critical threshold RH2; ② The water vapor concentration reaches or exceeds the critical threshold C2; ③ The difference between the ambient temperature and the dew point temperature is less than or equal to ΔT2.

[0040] Then, all the judgment results, collected data and issued control commands will be transmitted in real time to the external monitoring platform through the wireless data interaction terminal 36, so that staff can clearly see the data and realize visual supervision.

[0041] Step S4: The intelligent decision-making central module 35 distributes instructions to each execution component to achieve coordinated control. When the intelligent decision-making central module 35 determines that the state is normal, the controller of the intelligent decision-making central module 35 controls the micro air pump 66 in the electrically controlled ventilation window 6 to drive the rack 65 to drive the follower gear 64, so that the rubber sealing baffle 63 rotates until the electrically controlled ventilation window 6 is fully opened. At the same time, the controller of the intelligent decision-making central module 35 controls the micro motor 42 to drive the centrifugal fan 43 to run at low speed, so as to draw the air in the main box 1 to the outside of the main box 1, so as to realize the natural ventilation of the main box 1 to the outside. When the controller of the intelligent decision-making central module 35 determines that the condensation warning state has been activated, the controller of the intelligent decision-making central module 35 controls the electric ventilation window 6 to open, the centrifugal fan 43 in the dynamic ventilation assembly 4 to run at medium speed, and controls the convection fan 52 in the active condensation suppression device 5 to work at full load. When the convection fan 52 is working, it draws the air outside the installation chamber 51 into the convection chamber, which increases the air pressure in the convection chamber. This creates a pressure difference at both ends of the heat pipe 57, which in turn causes the air in the convection chamber to be filtered through the PTFE high-efficiency filter plate 53 (sealed installation through a slider-rail structure to ensure no leakage) and the polyester fiber layer 54 before entering the independent space in the convection chamber. From the independent space, the air enters the lower chamber of the main housing 1 through the heat pipe 57. With the medium-speed operation of the centrifugal fan 43, the air in the lower chamber then enters the upper chamber to replace the air in the main housing 1 and accelerate the ventilation of the main housing 1 to the outside.

[0042] When the controller of the intelligent decision-making central module 35 determines that there is a risk of condensation, the controller of the intelligent decision-making central module 35 controls the electric ventilation window 6 to open, the centrifugal fan 43 in the dynamic ventilation assembly 4 to run at high speed, the convection fan 52 in the active condensation suppression device 5 to work at full load, and controls the electric heating wire 56 to heat the air passing through the heat pipe 57, so that the air in the convection chamber is heated and enters the main box 1, thereby heating the air in the main box 1, and causing the moisture that may condense in the main box 1 to form water vapor and be drawn out to the outside of the main box 1 by the high-speed centrifugal fan 43.

[0043] The controller of the intelligent decision-making central module 35 also determines whether the duration of the condensation risk state is greater than or equal to a preset time threshold. If the duration of the condensation risk state is less than the preset time threshold, and the condensation risk state returns to the normal state and stabilizes for 5 minutes, the controller of the intelligent decision-making central module 35 automatically switches to the normal working mode. If the duration of the condensation risk state is greater than or equal to the preset time threshold (such as 10 minutes), the controller of the intelligent decision-making central module 35 generates an alarm signal and sends a fault warning to the external monitoring platform through the wireless data interaction terminal 36 to remind manual intervention.

[0044] In this embodiment, relying on the temperature and humidity detector 310 and the gas moisture detector 311, combined with dew point temperature for auxiliary verification, the temperature, humidity and water vapor concentration data inside the main chamber 1 are collected simultaneously and transmitted to the intelligent decision-making central module 35 for comparison and analysis, avoiding errors caused by single monitoring and ensuring accurate humidity judgment. The intelligent decision-making central module 35 classifies data into three states: normal, warning, and risk. It then links the dynamic ventilation assembly 4 (adjusting the speed of the centrifugal fan 43), the active condensation suppression device 5 (controlling the start / stop of the convection fan 52 and the electric heating wire 56), and the electrically controlled ventilation window 6 (adjusting the opening and closing of the rubber sealing baffle 63) to achieve precise control in different scenarios. Heating and dehumidification via the electric heating wire 56 and heat pipe 57, combined with ventilation and dehumidification by the centrifugal fan 43 and convection fan 52, forms a dual active control system. Under normal conditions, only low-speed ventilation and the sealing baffle are maintained, reducing unnecessary energy consumption and balancing control effectiveness with energy-saving requirements. The wireless data interaction terminal 36 uploads status data and fault warnings to an external platform in real time for convenient remote monitoring.

[0045] according to Figure 1 , Figure 2 and Figure 3 As shown, convection fans 52 are fixed on both sides of the convection chamber of the installation compartment 51. The convection chamber contains PTFE high-efficiency filter plates 53, with polyester fiber layers 54 filling the filter plates. These two components work together to provide secondary high-efficiency filtration of the intake air. An air guide tube extending into the heating chamber is connected to the center of the bottom of the convection chamber to guide airflow. A quick-release mounting plate 55 is installed on one side of the heating chamber. Electric heating wires 56 are arranged inside the plate, and are sleeved on the outside of heat-conducting pipes 57. One end of the heat-conducting pipe 57 extends to the lower chamber of the main housing 1, and the other end is threadedly connected to the air guide tube via an external nut 58, ensuring uniform heat transfer to the lower chamber of the main housing 1 and dissipation within the main housing 1. A glass wool insulation layer 59 is fixed around the inner wall of the heating chamber of the installation compartment 51, adhered to the inner wall with adhesive, to prevent heat leakage from the heating wires and ensure heating efficiency.

[0046] according to Figure 1 and Figure 4 As shown, the dual-modal humidity monitoring unit 3, with the sensor integration box 31 as its core, is fixed inside the main housing 1 by a mounting bracket 32 ​​and connected to an air intake 33 to draw air from the main housing 1. A stabilizing bracket 34 is installed inside the sensor integration box 31, housing the intelligent decision-making central module 35 and a fan 38, which draws air from the main housing 1 into the sensor integration box 31 via the air intake 33. A temperature and humidity detector 310 is installed in the stabilizing bracket 34 and electrically connected to the intelligent decision-making central module 35, directly detecting the temperature and humidity of the air inside the main housing 1. A gas moisture detector 311 is also installed in the stabilizing bracket 34 and electrically connected to the intelligent decision-making central module 35, assisting in detecting the water vapor concentration in the air. The temperature and humidity data, along with the water vapor concentration data, form a dual-dimensional humidity monitoring system, with the data transmitted in real-time to the intelligent decision-making central module 35 for analysis.

[0047] according to Figure 2 and Figure 5As shown, in the electrically controlled ventilation window 6, several rotating rods 62 are arranged and installed inside the frame 61. The rubber sealing baffles 63 on both sides of the rotating rods 62 have rounded chamfered edges. When the rubber sealing baffles 63 are closed, they can achieve a sealed isolation between the main housing 1 and the exhaust air guide channel 11, preventing external moisture from flowing back in. When the rubber sealing baffles 63 are open, they ensure smooth airflow. The micro air pump 66 provides driving force as a power source, which drives all the follower gears 64 and rotating rods 62 to rotate through the movement of the rack 65, ultimately realizing unified opening and closing control of the rubber sealing baffles 63 and quickly switching between sealing and ventilation modes.

[0048] according to Figure 1 and Figure 6 As shown, the dynamic ventilation assembly 4 uses a flexible silicone support 41 as a connection and buffer component. The flexible silicone support 41 utilizes its bendability to provide buffer support for the micro motor 42. The micro motor 42 serves as a power source to drive the centrifugal fan 43. By driving the centrifugal fan 43 to rotate, the air inside the main housing 1 is accelerated and discharged through the exhaust guide channel 11 and the inclined exhaust pipe 13, thereby achieving the function of dynamically adjusting the ventilation rate.

[0049] The overall effect achieved by the organization is as follows: After powering the system, the intelligent decision-making central module 35 automatically triggers a self-test command. It checks the connection status and basic functions of the dual-modal humidity monitoring unit 3, dynamic ventilation assembly 4, condensation active suppression device 5, and electrically controlled ventilation window 6 through the internal communication link. The self-test passes after each component returns a "normal" signal. If a component returns an abnormality, it sends a fault prompt to the external monitoring platform through the wireless data interaction terminal 36. The system restarts after the fault is cleared. After the self-inspection is passed, staff can preset core parameters through an external monitoring platform or by directly operating the wireless data interaction terminal 36. These parameters include: ① Dual humidity monitoring core parameters: relative humidity condensation warning threshold RH1, condensation critical threshold RH2; water vapor concentration condensation warning threshold C1, condensation critical threshold C2; ② Auxiliary verification thresholds: thresholds ΔT1 and ΔT2 for the difference between ambient temperature T and dew point temperature T_d; ③ Other parameters: monitoring frequency (e.g., once / minute), preset time threshold for condensation risk status (e.g., 10 minutes). All parameters are synchronously stored in the intelligent decision-making central module 35 as the core basis for subsequent state determination. The parameters can be flexibly adjusted according to the humidity characteristics of different regions and seasons.

[0050] The dual-modal humidity monitoring unit 3 accurately captures the humidity status inside the main housing 1 through the "active air extraction + dual-parameter synchronous detection" mode. The intelligent decision-making central module 35 periodically drives the low-noise motor 37 in the dual-modal humidity monitoring unit 3 to operate according to the preset monitoring frequency. The low-noise motor 37 drives the fan 38 to rotate at high speed, so that the air inside the main housing 1 is continuously drawn into the sensor integration box 31 to form a stable airflow sample channel. The fan 38 formed by the low-noise motor 37 and the fan blades can effectively reduce operating noise and avoid interfering with high-voltage equipment. The extracted air sample undergoes a dual detection process. First, the airflow comes into contact with the highly absorbent sponge layer 39 (which can absorb some water vapor to stabilize the detection environment) at the lower end of the stable support 34. The temperature and humidity detector 310 directly collects the air temperature and relative humidity data to form "basic humidity parameters". Second, the gas moisture detector 311 simultaneously collects the water vapor concentration data in the airflow to form "precise humidity supplementary parameters". The two sets of data are transmitted in real time to the intelligent decision-making central module 35 through signal lines to achieve dual-dimensional monitoring of "temperature and humidity + water vapor concentration" to eliminate single detection errors.

[0051] After receiving the data, the intelligent decision-making central module 35 compares it with the preset thresholds. Based on the comparison results, it divides the data into three operating states and generates corresponding control commands: If the relative humidity does not exceed the warning threshold RH1, the water vapor concentration does not exceed the warning threshold C1, and the difference between the ambient temperature and the dew point temperature is greater than ΔT1, that is, the humidity data in both dimensions are ≤ the condensation warning humidity threshold, it is judged as "normal state" and generates a "basic ventilation" command to save energy. If any of the following conditions are met, i.e., any humidity data > the warning threshold and < the critical threshold, it is judged as a "condensation warning state" and a "strengthened ventilation" instruction is generated to reduce humidity by increasing the air exchange rate: ① The relative humidity exceeds the warning threshold RH1 but does not reach the critical threshold RH2, the water vapor concentration does not exceed the warning threshold C1, and the difference between the ambient temperature and the dew point temperature is greater than ΔT2; ② The water vapor concentration exceeds the warning threshold C1 but does not reach the critical threshold C2, the relative humidity does not exceed the warning threshold RH1, and the difference between the ambient temperature and the dew point temperature is greater than ΔT2; ③ Both the relative humidity and the water vapor concentration exceed their respective warning thresholds, but the difference between the ambient temperature and the dew point temperature is greater than ΔT1. If any of the following conditions are met, i.e., any humidity data is greater than or equal to the critical threshold, it is judged as a "condensation risk state" and a "ventilation + heating dual suppression" instruction is generated. The "ventilation + heating dual suppression" instruction is generated to quickly reduce humidity by combining active heating with strong ventilation: ① The relative humidity reaches or exceeds the critical threshold RH2; ② The water vapor concentration reaches or exceeds the critical threshold C2; ③ The difference between the ambient temperature and the dew point temperature is less than or equal to ΔT2.

[0052] After the decision is made, the current data, status results, and all control commands will be uploaded to the external monitoring platform in real time through the wireless data interaction terminal 36 to achieve remote visual supervision; if a sudden increase in external humidity is detected, the platform can be used to switch to the early warning state in advance to achieve preventive control.

[0053] Under normal conditions, the micro air pump 66 of the electrically controlled ventilation window 6 drives the rack 65 to move horizontally, and through meshing with the follower gear 64, drives the rotating rod 62 to rotate, so that the rubber sealing baffle 63 is fully opened. At the same time, the micro motor 42 of the dynamic ventilation assembly 4 drives the centrifugal fan 43 to run at low speed. The air inside the box flows slowly and is discharged through the exhaust guide channel 11 and the inclined exhaust pipe 13.

[0054] In the condensation warning state, the electronically controlled ventilation window 6 keeps the baffle open, the centrifugal fan 43 of the dynamic ventilation assembly 4 is adjusted to medium speed to enhance exhaust suction, the convection fan 52 of the condensation active suppression device 5 is started, and the external air is guided to the main chamber 1 by the air guide tube and heat conduction pipe 57. The air inside the main chamber 1 is accelerated to be discharged by the centrifugal fan 43, forming an efficient circulation and rapid dehumidification.

[0055] In the event of condensation risk, the convection fan 52 of the active condensation suppression device 5 operates at full load and the heating wire 56 is activated. Heat is evenly transferred to the lower chamber of the main housing 1 and diffused to the upper chamber through the air in the heat pipe 57. The glass wool insulation layer 59 in the heating chamber of the installation compartment 51 prevents heat leakage. The centrifugal fan 43 of the dynamic ventilation assembly 4 is adjusted to high speed to quickly exhaust humid air. The electrically controlled ventilation window 6 keeps the baffle open to ensure airflow circulation.

[0056] When the system executes instructions, the dual-modal humidity monitoring unit 3 continuously monitors humidity to form a closed-loop control: the controller of the intelligent decision-making central module 35 times the duration of the condensation risk state in real time and compares it with the preset time threshold; ① If the duration of the condensation risk state is less than the preset threshold, and the state subsequently falls back to the normal state and stabilizes for 5 minutes, the controller automatically switches to the normal state working mode to avoid frequent mode switching due to short-term fluctuations and improve the stability of system operation; ② If the duration of the condensation risk state is greater than or equal to the preset threshold (e.g., 10 minutes), the controller generates an alarm signal and sends a fault warning to the external monitoring platform through the wireless data interaction terminal 36 to remind staff to manually intervene and investigate, preventing long-term condensation from damaging high-voltage equipment. Meanwhile, when the system executes instructions, the dual-modal humidity monitoring unit 3 continuously monitors the humidity to form a closed-loop control: the controller of the intelligent decision-making central module 35 keeps track of the duration of the condensation risk state in real time and compares it with the preset time threshold; ① if the state falls back to the normal state within the set time threshold and stabilizes for 5 minutes, then each component resumes normal operation; ② if the state is a condensation risk state and does not fall back for 10 minutes, then an alarm signal is sent through the wireless data interaction terminal 36 to remind the site to investigate and prevent long-term condensation from damaging the high-voltage equipment.

[0057] In addition, the system enhances reliability and ease of maintenance through structural design: the leak-proof top cover 12 is fixed with bolts to prevent rainwater from seeping in; the heating wire 56 of the active condensation suppression device 5 is movable and easy to replace vulnerable parts through the quick-release mounting plate 55; the HEPA particulate filter 21 of the base 2 and the PTFE high-efficiency filter plate 53 of the installation chamber 51 form a dual filtration system to ensure the cleanliness of the air inside the box and reduce the risk of damage to the insulation performance of high-voltage equipment.

A control method for a high-pressure equipment foundation condensation prevention and control system based on dual-dimensional humidity monitoring and intelligent linkage ventilation as described in any one of claims 1-7, characterized in that, The process is as follows: The intelligent decision-making central module (35) receives the temperature and humidity data obtained by the temperature and humidity detector (310) and the water vapor concentration data C in the air inside the main box (1) obtained by the gas moisture detector (311); The intelligent decision-making central module (35) will compare and analyze these two humidity data, determine the state of the system, and issue corresponding control commands. The specific comparison and judgment process is as follows: Set exclusive thresholds for different types of physical quantities, and preset auxiliary verification thresholds to improve the accuracy of judgment: ① Relative humidity exclusive thresholds: condensation warning threshold RH1 and condensation critical threshold RH2. These two thresholds are set according to the common condensation risk humidity range in the high-voltage equipment operating environment; ② Water vapor concentration exclusive thresholds: condensation warning threshold C1 and condensation critical threshold C2. These are set with reference to the safety standards for water vapor content in the high-voltage equipment moisture-proof design specifications; ③ Auxiliary verification thresholds: the difference thresholds ΔT1 and ΔT2 between ambient temperature T and real-time dew point temperature T_d. The dew point temperature T_d is calculated by the intelligent decision center module (35) based on relative humidity RH + ambient temperature T using the built-in dew point algorithm. The level of condensation risk can be further verified by the temperature difference. Layered comparison to determine system status: Normal state judgment: If the relative humidity RH does not exceed RH1, the water vapor concentration C does not exceed C1, and the difference between the ambient temperature T and the dew point temperature T_d is greater than ΔT1, it means that the air humidity inside the main box is low and the conditions for condensation are far away. Therefore, it is judged as a normal state, and the intelligent decision center module (35) issues an instruction to start basic ventilation. Condensation warning status judgment: If any of the following conditions are met, it means that the humidity inside the main box is close to the risk range, but has not yet reached the point where condensation will occur immediately. Therefore, it is judged as a condensation warning status, and the intelligent decision center module (35) issues an instruction to start enhanced ventilation: ① The relative humidity RH exceeds RH1 but is less than RH2, the water vapor concentration C does not exceed C1, and the difference between T and T_d is greater than ΔT2; ② The water vapor concentration C exceeds C1 but is less than C2, the relative humidity RH does not exceed RH1, and the difference between T and T_d is greater than ΔT2; ③ The relative humidity RH exceeds RH1 and the water vapor concentration C exceeds C1, but the difference between T and T_d is greater than ΔT1. Condensation risk status judgment: If any of the following conditions are met, it means that the main box is close to or has reached the conditions for condensation to form, and there is a clear risk of condensation. Therefore, it is judged as a condensation risk status. The intelligent decision center module (35) issues an instruction to start ventilation and heating dual suppression measures: ① The relative humidity RH reaches or exceeds RH2; ② The water vapor concentration C reaches or exceeds C2 (at this time, the water vapor content in the air is too high, and the probability of condensation is extremely high); ③ The difference between the ambient temperature T and the dew point temperature T_d is less than or equal to ΔT2. When the intelligent decision center module (35) determines that the state is normal, the intelligent decision center module (35) controls the electric ventilation window (6) to open and controls the centrifugal fan (43) in the dynamic ventilation assembly (4) to run at low speed to draw the air in the main box (1) to the outside of the main box (1) to achieve natural ventilation of the main box (1) to the outside. When the intelligent decision-making central module (35) determines that the condensation warning state is in effect, the intelligent decision-making central module (35) controls the ventilation window (6) to open, the centrifugal fan (43) in the dynamic ventilation assembly (4) to run at medium speed, and controls the convection fan (52) in the active condensation suppression device (5) to work at full load. When the convection fan (52) is working, it draws the air outside the installation chamber (51) into the convection chamber, which increases the air pressure in the convection chamber, thereby generating a pressure difference at both ends of the heat pipe (57), and then the air in the convection chamber enters the main box (1) through the heat pipe (57). With the medium speed operation of the centrifugal fan (43), the air in the main box (1) is replaced and the ventilation of the main box (1) to the outside is accelerated. When the intelligent decision-making central module (35) determines that there is a risk of condensation, the intelligent decision-making central module (35) opens the electrically controlled ventilation window (6), the centrifugal fan (43) in the dynamic ventilation assembly (4) runs at high speed, the convection fan (52) in the active condensation suppression device (5) works at full load, and controls the electric heating wire (56) to heat the air passing through the heat pipe (57), so that the air in the convection chamber is heated and enters the main box (1), thereby raising the temperature of the air in the main box (1), and then causing the moisture that may condense in the main box (1) to form water vapor and be drawn out to the outside of the main box (1) by the centrifugal fan (43).

9. The control method for the high-pressure equipment foundation condensation prevention and control system based on dual-dimensional humidity monitoring and intelligent linkage ventilation according to claim 8, characterized in that, The intelligent decision-making central module (35) compares the time in which the condensation risk state is in comparison with a preset time threshold. If the time in which the condensation risk state is in comparison with the preset time threshold, the intelligent decision-making central module (35) generates an alarm signal.
