Description

Technical Field

[0001] The invention relates to the field of high-voltage power distribution cabinets, and in particular to a high-voltage power distribution cabinet with a dehumidification function and a control system thereof. Background Art

[0002] At present, in modern industrial and civil buildings, high-voltage distribution cabinets are an important part of the power system, and their stability and reliability are crucial to the entire power supply. However, due to changes in environmental humidity, moisture is easily generated inside the high-voltage distribution cabinet, causing components to become damp, thus affecting the normal operation of the distribution cabinet and even causing safety accidents. Although traditional distribution cabinets have certain moisture-proof functions, they often cannot effectively cope with the dehumidification needs in high humidity environments.

[0003] In patent 202311626799.0, it is proposed to set a dehumidification component for the distribution cabinet. When the external electronic components are installed into the cabinet through the assembly rack, the dehumidification ball moves irregularly inside the dehumidification box, so that the dehumidification ball absorbs moisture and dehumidifies the moisture inside the cabinet through the dehumidification box, so that the inside of the cabinet is in a relatively dry environment to ensure the working environment and stability of the electronic components inside the cabinet, and avoid the cabinet being too humid during operation, which causes the electronic components to be damp and malfunction, thereby improving the service life and safety of the cabinet. By setting a wind circulation component, when the dehumidification ball is located inside the dehumidification box for dehumidification, air is continuously transported to the inside of the dehumidification box, so that the dehumidification ball is affected by the wind and moves irregularly inside the dehumidification box, absorbing moisture and dehumidifying the air inside the cabinet, and at the same time, suction is generated to suck and transfer the dehumidification ball after it is saturated with moisture inside the retention barrel, so as to avoid the dehumidification ball being difficult to move and transfer when in use, thereby improving the dehumidification effect and convenience of use of the dehumidification ball. By arranging the inlet tube, the exhaust tube and the partition net, when the positive blade fan and the reverse blade fan are in operation, the air blown out by the positive blade fan and the air sucked by the reverse blade fan are guided, so that the positive blade fan can input the air outside the cabinet into the inside of the cabinet, and the reverse blade fan can extract the air inside the cabinet out of the cabinet. At the same time, a circulation pipeline is provided for the circulating dehumidification ball, thereby improving the circulation effect of the air inside the cabinet and the dehumidification ball.

[0016] The technical solution of the present invention is further described in detail below through the accompanying drawings and embodiments. BRIEF DESCRIPTION OF THE DRAWINGS

[0017] The accompanying drawings are used to provide a further understanding of the present invention and constitute a part of the specification. Together with the embodiments of the present invention, they are used to explain the present invention and do not constitute a limitation of the present invention.

[0018] The preferred embodiments of the present invention are described below in conjunction with the accompanying drawings. It should be understood that the preferred embodiments described herein are only used to illustrate and explain the present invention, and are not used to limit the present invention.

[0019] like Figure 1 As shown, this embodiment provides a high-voltage distribution cabinet with a dehumidification function proposed by the present invention, and the high-voltage distribution cabinet includes: A humidity sensing component, including an infrared humidity detector and a humidity sensing device, which is used to generate a control signal, wherein the humidity sensing device is used to determine the air humidity in the high-voltage distribution cabinet, and the infrared humidity detector is used to determine the humidity of components in the high-voltage distribution cabinet; A dehumidification component, comprising a wind-heating device and an adsorption device, wherein the wind-heating device is used to perform wind-heat dehumidification on the wet components, and the adsorption device is used to adsorb evaporated water during the dehumidification process, and the adsorption device comprises a drainage channel connected to an external condenser, and an air-drying duct equipped with an adsorption box, and the air-drying duct and the drainage channel are isolated by an adsorbent; The circulation pipeline comprises a first pipeline and a second pipeline, wherein the first pipeline is connected to the heat flow input end of the wind heating device, and the second pipeline is connected to the air drying duct output end of the adsorption device.

[0020] The present invention proposes a high-voltage power distribution cabinet with a dehumidification function. The power distribution cabinet integrates multiple components such as humidity sensing, dehumidification and circulation pipelines to form an efficient dehumidification system. Among them, the humidity sensing component can monitor the humidity conditions inside and outside the power distribution cabinet in real time through an infrared humidity detector and a humidity sensor device, providing accurate data support for the operation of the dehumidification system. The dehumidification component adopts a combination of a wind heating device and an adsorption device, which can not only quickly dehumidify the wet components, but also effectively collect and remove evaporated moisture through the adsorption device to maintain a dry environment inside the power distribution cabinet.

[0021] In addition, the setting of the circulation pipeline enables heat energy and air flow to circulate efficiently inside the distribution cabinet, ensuring the uniformity and durability of the dehumidification effect. This high-voltage distribution cabinet with dehumidification function not only improves the operating stability of the power system, but also extends the service life of components and reduces the failure rate and maintenance costs caused by humidity problems.

[0022] The size of the power distribution cabinet is 2 meters × 1.5 meters × 1.2 meters, which is suitable for indoor environments. In the humidity sensing component, the infrared humidity detector is installed on the top of the power distribution cabinet, and the humidity sensing devices are distributed in key positions in the cabinet. The wind and heat device in the dehumidification component is installed on the side of the cabinet, and the adsorption device is located at the bottom of the cabinet and connected to the external condenser through a drainage channel.

[0023] When the humidity sensor detects that the air humidity in the cabinet exceeds the set threshold, the infrared humidity detector starts to work and judges the humidity status of the components. Once the components are found to be damp, the wind heating device starts to blow hot air to the components through the first pipeline of the circulation pipeline for dehumidification. At the same time, the air drying duct of the adsorption device is opened, and the evaporated water is collected through the second pipeline, and dried through the adsorbent in the adsorption box. The water flows into the external condenser through the drainage channel and is finally discharged from the distribution cabinet.

[0024] The present invention can quickly and effectively dehumidify the interior of the high-voltage distribution cabinet through the combined action of the wind heating device and the adsorption device to ensure the dryness of the components. The humidity sensing component can monitor humidity changes in real time and start the dehumidification program in time to prevent components from being damaged by moisture. The design of the circulation pipeline allows heat energy and airflow to circulate efficiently, improves dehumidification efficiency, and reduces energy consumption. By removing moisture, electrical failures caused by humidity are reduced, and the safety and reliability of the distribution cabinet are improved. As an embodiment of the present invention, the infrared humidity detector comprises: The first input terminal is used to obtain an infrared spectrum image of any component in the high-voltage power distribution cabinet; wherein the infrared spectrum image is a temperature infrared spectrum image of the corresponding component in the high-voltage power distribution cabinet; The second input terminal is used to obtain the power spectrum of any component in the high-voltage distribution cabinet; wherein the power spectrum is the operating power conversion spectrum of the corresponding component in the high-voltage distribution cabinet; A first processing unit is used to generate a first interference function based on humidity interference according to the temperature infrared spectrum image and the operation power conversion spectrum, and determine whether the humidity values ​​corresponding to the temperature infrared spectrum image and the operation power conversion spectrum are consistent; The output terminal element is used to determine the first real-time humidity value when the humidity values ​​corresponding to the temperature infrared spectrum image and the operating power conversion spectrum are consistent, and when the humidity values ​​corresponding to the temperature infrared spectrum image and the operating power conversion spectrum are inconsistent, call the humidity association spectrum of the corresponding component in the preset database, match the humidity association spectrum with the temperature infrared spectrum image and the operating power conversion spectrum respectively, determine the closest association spectrum, and use the humidity value corresponding to the closest association spectrum as the second real-time humidity value.

[0025] The infrared humidity detector is an important humidity sensing component that can more accurately and quickly determine the humidity status of each component in the high-voltage distribution cabinet. The infrared humidity detector mainly includes two input ports, one for receiving the infrared image of any component in the high-voltage distribution cabinet, and the other for receiving the operating power of this component. Through these two input ports, the infrared humidity detector can obtain accurate humidity information.

[0026] The infrared humidity detector uses a series of processing units to process the received information. First, it generates a first interference function based on humidity interference according to the received infrared image and operating power. The main function of this function is to determine whether the humidity values ​​corresponding to the received infrared image and the operating power are consistent. If they are consistent, then this function will output a real-time humidity value. If they are inconsistent, then this function will call a preset database, find the humidity correlation map of the corresponding component from the database, and then determine the closest correlation map through matching, and use the humidity value corresponding to this map as the second real-time humidity value. In this way, even in the presence of some interference factors, the humidity status in the high-voltage distribution cabinet can be accurately judged. As an embodiment of the present invention, the humidity sensing device comprises: The clock signal processing end is used to set multiple monitoring cycles and collect humidity data for the high-voltage distribution cabinet according to the monitoring cycle; The superposition mean end is used to determine the humidity mean by accumulating and averaging the humidity data based on the monitoring period and treating the adjacent monitoring periods as a mean value group; The humidity processing end is used to determine whether the humidity mean exceeds the preset humidity threshold value. When any humidity mean value exceeds the preset humidity threshold value, a dehumidification signal is generated.

[0027] In specific implementation, the humidity sensing device includes a clock signal processing end, which can set multiple monitoring cycles and collect humidity data for the high-voltage distribution cabinet according to the monitoring cycle. At the same time, it also includes a superposition average end, which can accumulate and average the humidity data of adjacent monitoring cycles according to the monitoring cycle and determine the humidity average. Finally, it also includes a humidity processing end, which can make an over-limit judgment on the obtained humidity average according to the preset humidity threshold. When the humidity average of any group exceeds the preset humidity threshold, a dehumidification signal will be generated.

[0028] Such a design can greatly improve the accuracy and reliability of humidity measurement, because each measurement is carried out within a fixed period, and the humidity data within each period will be carefully calculated and compared. In this way, the influence of some accidental errors can be eliminated, making the measurement results more stable and reliable. At the same time, by timely alarming any abnormal situation of any set of data, problems can be discovered more quickly to avoid serious problems with the equipment.

[0029] As an embodiment of the present invention, the infrared humidity detector and humidity sensing device further include the following dehumidification component determination step: Step 1: In response to the dehumidification signal input by the humidity sensing device, a multi-angle humidity inspection is performed through an infrared humidity detector to determine the position data of the components that need to be dehumidified; Step 2: Input the component location data into the trained classifier to output the first dehumidification strategy of the corresponding component; wherein the dehumidification strategy includes dehumidification temperature, dehumidification time and dehumidification air volume intensity; Step 4: Based on the dehumidification strategy, determine whether there are components that need multiple rounds of dehumidification treatment, and generate a second dehumidification strategy; Step 5: When there are multiple rounds of dehumidification treatment, the first dehumidification strategy and the second dehumidification strategy are temporally and spatially sorted, and based on the temporal and spatial sorting results, a multiple round dehumidification model is determined; Step 6: When there are no multiple rounds of dehumidification treatment, the dehumidification time of each component in the first dehumidification strategy is sorted in time and space to generate a dehumidification time interval model; Step 7: Based on the multi-round dehumidification model and the dehumidification time interval model, a control signal of the dehumidification component is generated.

[0030] In the specific implementation, step 1: respond to the dehumidification signal output by the humidity sensing device, conduct a multi-angle humidity inspection through the infrared humidity detector, and determine the position data of the components that need to be dehumidified. Step 2: Input the position data of the components into the trained classifier to output the first dehumidification strategy for the corresponding components. This classifier can be a neural network classifier based on deep learning, which can automatically learn and optimize the dehumidification strategy to obtain the optimal dehumidification effect. Step 4: Based on the dehumidification strategy, determine whether there are components that need multiple rounds of dehumidification treatment, and generate a second dehumidification strategy. This judgment process can be completed by analyzing the humidity status of different components and comparing the effects of different dehumidification strategies. If there are multiple rounds of dehumidification treatment, proceed to the next step. Step 5: When there are multiple rounds of dehumidification treatment, sort the first dehumidification strategy and the second dehumidification strategy in time and space, and determine the multiple rounds of dehumidification model based on the time and space sorting results. This step can determine the best dehumidification model by analyzing the application effects of different dehumidification strategies at different times and different locations. Step 6: When there is no multi-round dehumidification treatment, the dehumidification time of each component in the first dehumidification strategy is sorted in time and space to generate a dehumidification time interval model. This step can determine the optimal dehumidification time interval model by analyzing the use of different dehumidification strategies, thereby ensuring that each component can be fully dehumidified. Step 7: Based on the multi-round dehumidification model and the dehumidification time interval model, generate the control signal of the dehumidification component. This step can obtain the most suitable dehumidification control signal for each component through comprehensive analysis and optimization of these models, thereby ensuring the stable operation of the equipment. As an embodiment of the present invention, the wind heating device includes: A hot air unit, comprising a full-angle adjustment mechanism and a multi-frequency hot air blower installed on the full-angle adjustment structure; The angle control unit is used to obtain the target dehumidification components, perform multi-target segmentation on the target dehumidification components, and determine the dehumidification angle of each dehumidification component based on the multi-target segmentation to construct the dehumidification component coordinate information; the wind and heat parameter configuration unit is used for the angle control parameters, dehumidification time, wind flow, dehumidification range and temperature parameters of the hot air unit.

[0031] In a specific implementation, the wind-heating device includes a hot air unit, which includes a full-angle adjustment mechanism, on which a multi-frequency hot air blower is installed, which can achieve precise control of the air temperature in the working area. At the same time, the device also includes an angle control unit for obtaining the position information of the target dehumidification component, and then performing multi-target segmentation on the target dehumidification component, and according to the result of the multi-target segmentation, determining the dehumidification angle of each dehumidification component, and constructing the coordinate information of the dehumidification component. In this way, the working angle of each dehumidification component can be accurately controlled to achieve the best dehumidification effect. The wind-heating device also includes a wind-heating parameter configuration unit for setting the angle control parameters, dehumidification time, wind flow, dehumidification range and temperature parameters of the hot air unit, so as to provide a preset parameter for the entire dehumidification process. Such a design can make the system more intelligent and improve work efficiency and dehumidification effect.

[0033] During specific implementation, the function of the wind-heat parameter configuration unit is to receive control signals from the humidity sensing component and determine the dehumidification demand parameters of the dehumidification components based on these signals. Then, based on these demand parameters, the wind-heat parameter configuration unit will use the existing data models of dehumidification distance, dehumidification angle, dehumidification level and dehumidification air volume intensity to build a dehumidification control model. This model will be used as the basis for the subsequent generation of control parameter information. Then, based on the generated control parameter information, the wind-heat parameter configuration unit will generate the angle control parameters, dehumidification time, air flow, dehumidification range and temperature parameters of the hot air unit. These parameters will guide and control the operation of the hot air unit, thereby achieving effective dehumidification of humid components. As an embodiment of the present invention, the air-drying duct is further provided with a chain circulation component, and the chain circulation component is used to cyclically transport the adsorption box to the tail of the air-drying duct and between the air-drying duct and the drainage channel.

[0034] The chain circulation component can be composed of a series of annular components and transmission components, wherein the annular component includes an adsorption box and a transmission component, wherein the transmission component can be a motor or an electromagnetic drive component, wherein the adsorption box is used to adsorb evaporated water during the dehumidification process, wherein the annular components are connected in a chain to form a circulation path, and wherein the transmission component can enable the annular components to move along the circulation path.

[0035] A chain circulation component may also be arranged between the air-drying duct and the drainage duct, and the chain circulation component may transport the adsorption box in the air-drying duct to a position between the air-drying duct and the drainage duct through a chain connection, so as to replenish the adsorption box in time and improve the dehumidification efficiency.

[0036] The infrared measuring instrument can be installed inside the high-voltage power distribution cabinet. The infrared measuring instrument can obtain information such as the surface temperature and color of the measured object by measuring the infrared spectrum of the surface of the measured object, and compare this information with the control signal to determine whether the actual state meets the expected state, thereby realizing automatic control of the high-voltage power distribution cabinet.
