Description

Technical Field

[0001] The present invention relates to the technical field of outdoor boxes, and in particular to an anti-condensation outdoor box, and an anti-condensation outdoor box control method and equipment. Background Art

[0002] An outdoor box refers to a switch box placed outdoors for installing electrical components. Due to the high humidity and large temperature difference in the outdoor environment, condensation is likely to occur inside the outdoor box, especially in coastal areas and northeast and northwest regions due to high humidity or large temperature difference between day and night. Condensation is more likely to form, which can cause surface corrosion of electrical equipment, reduce insulation performance, cause flashover and creepage, and even cause short circuits. If electrical components operate in a high humidity environment for a long time, the life of the electrical components will be shortened. In particular, when condensation on the top cover drips onto live components, it will cause a short circuit or even a fire, which is very harmful to the electrical box.

[0003] The Chinese invention patent with application number CN201910895968.8 discloses an anti-condensation structure for an outdoor electrical box, which at least includes an electrical box body, a box top cover and a box base. The inner surface of the top cover of the electrical box is sprayed with a super-hydrophilic coating, and the surface water drop contact angle of the super-hydrophilic coating is less than 5°. When the water vapor in the air in the box is saturated, the water vapor can also completely wet and spread on its surface, and will not condense into particles to form condensation. The anti-condensation structure of the outdoor electrical box only passively prevents the condensation formed on the inner wall of the top cover of the electrical box from dripping on the surface of the electrical components through the top cover structure and the spraying of the super-hydrophilic coating on the inner wall of the top cover. It does not detect the changes in temperature and humidity inside the outdoor box and actively adjust the temperature difference between the air inside and outside the outdoor box. It cannot effectively avoid the occurrence of condensation. The degree of intelligence is low and needs to be improved. Summary of the invention

[0055] The “first” and “second” mentioned in the present invention do not represent specific quantities and orders, but are merely used to distinguish names.

[0056] Embodiment 1:

[0057] Most of the existing outdoor box shells are made of metal, and metal has a faster heat transfer rate. The temperature and humidity inside the outdoor box are easily affected by the outdoor environment, especially in the coastal areas and the northeast and northwest regions. Due to high humidity or large temperature difference between day and night, condensation is easily formed. Condensation can cause surface corrosion of electrical equipment and performance degradation or even damage of electrical components. The existing outdoor box anti-condensation structure passively prevents condensation formed on the inner wall of the top cover of the electrical box from dripping on the surface of electrical components through structural settings, such as applying a super-hydrophilic coating on the top cover. However, condensation will still occur due to the high humidity and large temperature difference of the outdoor electrical box. Therefore, it is necessary to improve the outdoor box to actively avoid the occurrence of condensation to better ensure the safe and effective operation of electrical components.

[0058] In order to solve the problems existing in the existing outdoor box anti-condensation structure, this embodiment provides an anti-condensation outdoor box, such as Figure 1As shown, it includes a housing 1, a top cover 2 installed on the top of the housing, and a base 3 installed on the bottom of the housing. The housing 1, the top cover 2 and the base 3 enclose an installation space for installing electrical components. The housing is provided with an air inlet 4 and an air outlet 5. The electrical components include but are not limited to circuit breakers, disconnectors, instruments, terminals, busbars, etc.

[0059] The anti-condensation outdoor box also includes a first data acquisition component, a dew point adjustment component and a controller.

[0060] The first data acquisition component is used to collect first basic real-time data related to the dew point temperature of the first target area in the outdoor box.

[0061] Preferably, the first data acquisition module includes a first temperature sensor, a first humidity sensor and a first air pressure sensor installed around the first target area, the first basic real-time data includes a first basic real-time air temperature, a first basic real-time air humidity and a first basic real-time air pressure, and the first temperature sensor, the first humidity sensor and the first air pressure sensor are all electrically connected to the controller.

[0062] The first data acquisition component also includes an external air temperature sensor for acquiring the external air temperature of the outdoor box. The first basic real-time data also includes the external air temperature. The first basic real-time air humidity is preferably the relative humidity value of the air.

[0063] A dew point temperature comparison table is pre-stored in the controller. After obtaining the first basic real-time air temperature, the first basic real-time air humidity, and the first basic real-time air pressure, the controller can obtain the corresponding dew point temperature by querying the dew point temperature comparison table.

[0064] The difference between the first base real-time air temperature and the dew point temperature represents how close the air is to saturation.

[0065] The dew point adjustment component is used to respond to the real-time adjustment action instruction to adjust the first real-time status data of the first target area in the outdoor box.

[0066] The first real-time status data includes but is not limited to the real-time temperature value and the real-time humidity value of the first target area in the outdoor box. The dew point adjustment component includes but is not limited to a ventilation component for adjusting the air temperature of the first target area or a temperature adjustment component (such as a heating component or a cooling unit) for adjusting the temperature of the first target area.

[0067] The controller is used to calculate the air saturation level of the first target area based on the first basic real-time data, generate a real-time adjustment action instruction and send it to the dew point adjustment component when the air saturation level is less than a preset saturation level threshold, and control the action of the dew point adjustment component according to the real-time adjustment action instruction to adjust the first real-time status data of the first target area to achieve anti-condensation operation.

[0068] A preset saturation threshold is pre-stored in the controller. The purpose of generating a real-time adjustment action instruction when the air saturation is less than the preset saturation threshold is to adjust the temperature or air temperature of the first target area through the dew point adjustment component, actively reduce the temperature difference between the first target area in the outdoor box and the external air, avoid the occurrence of condensation in the outdoor box, so as to better realize the anti-condensation operation and improve the working performance and life of the electrical components in the outdoor box.

[0069] That is to say, the anti-condensation outdoor box collects the first basic real-time data related to the dew point temperature of the first target area in the outdoor box, calculates the air saturation level of the first target area, generates a real-time adjustment action instruction and sends it to the dew point adjustment component when the air saturation level is less than the preset saturation level threshold, and actively controls the action of the dew point adjustment component according to the real-time adjustment action instruction to adjust the first real-time status data of the first target area to realize anti-condensation operation, which can effectively avoid the occurrence of condensation and improve the intelligence level of anti-condensation of the outdoor box.

[0070] Preferably, the controller includes a real-time instruction generating unit, a condensation probability calculating unit and a preparatory instruction calculating unit.

[0071] The real-time instruction generating unit is used to generate a real-time adjustment action instruction when the air saturation level is less than a preset saturation level threshold, and send the real-time adjustment action instruction to the dew point adjustment component.

[0072] The condensation probability calculation unit is used to obtain the predicted condensation probability of the first target area according to the first basic historical data and the first basic real-time data.

[0073] Specifically, the first basic historical data includes first basic historical temperature, humidity and air pressure data, and a neural network model is constructed and trained using the first basic historical data. The trained neural network model is used to calculate a preset condensation probability of the first target area in the next preset time period. According to the trained neural network model and the first basic real-time data, the predicted condensation probability of the first target area is obtained.

[0074] Preferably, first basic prediction data is obtained according to the trained neural network model and the first basic real-time data, and the predicted condensation probability of the first target area is obtained according to the first basic prediction data.

[0075] The predicted condensation probability p1 of the first target area = 1-(t1-TD1 / TD1)*100%, wherein t1 represents the average value of the first basic predicted air temperature of the first target area, and TD1 represents the average value of the first basic predicted dew point temperature of the first target area in the next preset time period.

[0076] The next preset time period takes the current time as the time starting point and the time ending point is calculated based on the width of the preset time period.

[0077] The preparatory instruction generating unit is used to generate a preparatory adjustment action instruction when the predicted condensation probability is greater than a preset probability threshold and the air saturation level is not less than the preset saturation level threshold, and send the preparatory adjustment action instruction to the dew point adjustment component.

[0078] The dew point adjustment component is also used to respond to the preparatory adjustment action instruction and enter a preparatory state matching the preparatory adjustment action instruction.

[0079] Here, the preparatory state may be a standby state, that is, a low-speed operation state.

[0080] By acquiring first basic historical data, the predicted condensation probability of the first target area is acquired according to the basic historical data and the first basic real-time data, and when the predicted condensation probability is greater than a preset probability threshold and the air saturation level is not less than the preset saturation level threshold, a preparatory adjustment action instruction is generated, so that the dew point adjustment component responds to the preparatory adjustment action instruction and enters a preparatory state matching the preparatory adjustment action instruction. When the outdoor box is in a normal state and condensation is likely to occur next, the dew point adjustment component can be prepared in advance and then in a preparatory state, thereby further improving the degree of intelligence while improving the response speed of anti-condensation.

[0081] In addition, by acquiring the predicted condensation probability of the first target area, the active anti-condensation function of the outdoor switch box can also be better implemented.

[0082] Preferably, if Figure 2 As shown, the dew point adjustment assembly includes a bracket 6, a fan and a plurality of ventilation ducts.

[0083] The bracket 6 is fixed on the side panel of the housing 1; the fan (not shown in the figure) is fixedly mounted on the bracket 6, and its inlet is connected to the air inlet; the inlets of multiple ventilation ducts (not shown in the figure) are connected to the outlets of the fan, and a ventilation regulating valve is installed on each ventilation duct.

[0084] The ventilation regulating valve is connected to the controller signal, and the controller controls the opening size and opening and closing of the ventilation regulating valve by sending a command signal to the ventilation regulating valve.

[0085] Wherein, a plurality of ventilation ducts form a plurality of different ventilation paths in the outdoor box.

[0086] Specifically, the ventilation duct can be installed along the side panel of the housing, passing through the center, edge or top of the first target area and the plurality of second target areas, and ventilation holes are opened on the side walls of the ventilation duct facing the first target area and the second target area. The plurality of ventilation ducts pass through the first target area and the plurality of second target areas in different ways to form a plurality of different ventilation paths. Of course, a plurality of different ventilation paths can also be formed by setting the orientation angle of the ventilation duct.

[0087] By controlling the opening of the ventilation regulating valve through the controller, different ventilation paths can be selected as needed to ventilate the first target area and multiple second target areas, so that the temperature difference of the air inside and outside the outdoor box is reduced, avoiding the occurrence of condensation, and performing overall anti-condensation operations on the outdoor box.

[0088] Preferably, a plurality of second data acquisition components are also installed in the housing.

[0089] The plurality of second data acquisition components are used to respectively acquire second basic real-time data related to the dew point temperature of a plurality of second target areas in the outdoor box.

[0090] The controller is also used to calculate the total condensation probability index of the first target area and multiple second target areas under each of the ventilation paths based on the first basic real-time data and the second basic real-time data, select the optimal one from the multiple ventilation paths based on the total condensation probability index, and generate real-time adjustment action instructions based on the optimal ventilation path.

[0092] By setting up multiple ventilation ducts, multiple different ventilation paths are formed in the outdoor box, the total condensation probability index of each ventilation path is calculated, and the optimal one is selected from the multiple ventilation paths according to the total condensation probability index. According to the optimal ventilation path, real-time adjustment action instructions are generated, and overall anti-condensation operations can be performed for multiple different target areas in the outdoor box, thereby improving the overall efficiency of anti-condensation in multiple different areas of the outdoor box, ensuring the safety and stability of the operation of electrical components in the outdoor box, and thus increasing the service life of the electrical components.

[0121] Specifically, the ventilation duct can be installed along the side panel of the housing, passing through the center, edge or top of the first target area and the plurality of second target areas, and ventilation holes are opened on the side walls of the ventilation duct facing the first target area and the second target area. The plurality of ventilation ducts pass through the first target area and the plurality of second target areas in different ways to form a plurality of different ventilation paths. Of course, a plurality of different ventilation paths can also be formed by setting the orientation angle of the ventilation duct.

[0122] By controlling the opening of the ventilation regulating valve through the controller, different ventilation paths can be selected as needed to ventilate the first target area and multiple second target areas, so that the temperature difference of the air inside and outside the outdoor box is reduced, avoiding the occurrence of condensation, and performing overall anti-condensation operations on the outdoor box.

[0123] Preferably, a plurality of second data acquisition components are also installed in the housing.

[0124] The plurality of second data acquisition components are used to respectively acquire second basic real-time data related to the dew point temperature of a plurality of second target areas in the outdoor box.

[0125] The controller is also used to calculate the total condensation probability index of the first target area and multiple second target areas under each of the ventilation paths based on the first basic real-time data and the second basic real-time data, select the optimal one from the multiple ventilation paths based on the total condensation probability index, and generate real-time adjustment action instructions based on the optimal ventilation path.

[0126] Specifically, the second data acquisition module includes a second temperature sensor, a second humidity sensor and a second air pressure sensor installed around the second target area, the second basic real-time data includes a second basic real-time air temperature, a second basic real-time air humidity and a second basic real-time air pressure, and the second temperature sensor, the second humidity sensor and the second air pressure sensor are all electrically connected to the controller.

[0127] The total condensation probability index of the optimal ventilation path is the largest.

[0128] By setting up multiple ventilation ducts, multiple different ventilation paths are formed in the outdoor box, the total condensation probability index of each ventilation path is calculated, and the optimal one is selected from the multiple ventilation paths according to the total condensation probability index. According to the optimal ventilation path, real-time adjustment action instructions are generated, and overall anti-condensation operations can be performed for multiple different target areas in the outdoor box, thereby improving the overall efficiency of anti-condensation in multiple different areas of the outdoor box, ensuring the safety and stability of the operation of electrical components in the outdoor box, and thus increasing the service life of the electrical components.

[0129] This embodiment also provides a method for controlling an anti-condensation outdoor cabinet. Figure 3 As shown, it includes the following steps:

[0130] S1, collecting first basic real-time data related to the dew point temperature of the first target area in the outdoor box.

[0131] S2, calculating the air saturation of the first target area according to the first basic real-time data, and generating a real-time adjustment action instruction when the air saturation is less than a preset saturation threshold.

[0132] S3, responding to the real-time adjustment action instruction, adjusting the first real-time status data of the first target area in the outdoor box to implement an anti-condensation operation.

[0133] The anti-condensation outdoor box control method collects first basic real-time data related to the dew point temperature of a first target area in the outdoor box, calculates the air saturation level of the first target area, generates a real-time adjustment action instruction and sends it to the dew point adjustment component when the air saturation level is less than a preset saturation level threshold, and actively controls the action of the dew point adjustment component according to the real-time adjustment action instruction to adjust the first real-time status data of the first target area to implement anti-condensation operation, which can effectively avoid the occurrence of condensation and improve the intelligence level of anti-condensation of the outdoor box.

[0134] Preferably, if Figure 4 As shown, the anti-condensation outdoor box control method also includes the following steps:

[0135] S4: Obtain the predicted condensation probability of the first target area according to the basic historical data and the first basic real-time data.

[0136] S5, when the predicted condensation probability is greater than a preset probability threshold and the air saturation level is not less than the preset saturation level threshold, generating a preparatory adjustment action instruction.

[0137] S6, the dew point adjustment component responds to the preparatory adjustment action instruction and enters a preparatory state matching the preparatory adjustment action instruction.

[0138] By acquiring first basic historical data, the predicted condensation probability of the first target area is acquired according to the basic historical data and the first basic real-time data, and when the predicted condensation probability is greater than a preset probability threshold and the air saturation level is not less than the preset saturation level threshold, a preparatory adjustment action instruction is generated, so that the dew point adjustment component responds to the preparatory adjustment action instruction and enters a preparatory state matching the preparatory adjustment action instruction. When the outdoor box is in a normal state and condensation is likely to occur next, the dew point adjustment component can be prepared in advance and then in a preparatory state, thereby further improving the degree of intelligence while improving the response speed of anti-condensation.

[0139] In addition, by acquiring the predicted condensation probability of the first target area, the active anti-condensation function of the outdoor switch box can also be better implemented.

[0140] Preferably, if Figure 5 As shown, the anti-condensation outdoor box control method also includes the following steps:

[0141] S7, respectively collecting second basic real-time data related to the dew point temperature of multiple second target areas in the outdoor box.

[0142] S8, calculating a total condensation probability index of the first target area and a plurality of the second target areas under each of the ventilation paths according to the first basic real-time data and the second basic real-time data.

[0143] S9: Selecting an optimal one from the multiple ventilation paths according to the total condensation probability index.

[0144] Among them, in step S2, the specific method of generating a real-time adjustment action instruction when the air saturation level is less than the preset saturation level threshold includes: S10, when the air saturation level is less than the preset saturation level threshold, generating a real-time adjustment action instruction according to the optimal ventilation path.

[0145] By setting up multiple ventilation ducts, multiple different ventilation paths are formed in the outdoor box, the total condensation probability index of each ventilation path is calculated, and the optimal one is selected from the multiple ventilation paths according to the total condensation probability index. According to the optimal ventilation path, real-time adjustment action instructions are generated, and overall anti-condensation operations can be performed for multiple different target areas in the outdoor box, thereby improving the overall efficiency of anti-condensation in multiple different areas of the outdoor box, ensuring the safety and stability of the operation of electrical components in the outdoor box, and thus increasing the service life of the electrical components.

[0146] This embodiment also provides a computer-readable storage medium storing a computer program, which implements the anti-condensation outdoor box control method when the computer program is executed by a processor.

[0147] The present invention also provides an anti-condensation outdoor box control device, which includes:

[0148] Controller;

[0149] A memory storing executable instructions;

[0150] Among them, the executable instructions can be run on the controller and implement the anti-condensation outdoor box control method.

[0151] Embodiment three:

[0152] It should be understood that this embodiment includes all the technical features of the above embodiments and is further specifically elaborated on the basis of the above embodiments.

[0153] In this embodiment, the specific structure of the anti-condensation outdoor box is further described. In this embodiment, the first target area is the bottom surface of the top cover, the second target area is the surface of the four side panels of the front, back, left and right of the shell located inside the outdoor box, the inner diameter of the ventilation duct is between 1.5CM and 2.5CM, the wall thickness is between 2mm-4mm, and it is made of plastic or rubber to ensure its air insulation performance.

[0154] The width of the top cover ranges from 1.0M to 1.2M, the length ranges from 1.5M to 2.5M, the length of the side panel is between 2M and 3M, the diameter of the ventilation hole is between 3mm and 4mm, and the ventilation duct is located above the first target area and the second target area, the distance between the ventilation duct and the first target area and the second target area is 5-8mm, each ventilation duct is of equal length and no more than 35M in length, the number of ventilation holes on the ventilation duct corresponding to the first target area and each second target area is no more than 3, and the fan speed is between 6.5m / s and 10.9m / s.

[0155] Based on the specific structure and parameters of the above-mentioned anti-condensation outdoor box, the total condensation probability index of each ventilation path is in,

[0156] Where, L represents the length of the ventilation duct, L 1 represents the length of the ventilation duct from one of the ventilation holes to the ventilation duct inlet corresponding to the first target area, L 2irepresents the length of the ventilation duct from one of the ventilation holes of the ventilation duct corresponding to the i-th second target area to the ventilation duct entrance, n represents the number of second target areas, T0 represents the outside air temperature, T1 represents the first basic real-time air temperature of the first target area, T2 represents the second basic real-time air temperature of the second target area, TD1 represents the dew point temperature of the first target area, TD 2i represents the dew point temperature of the i-th second target area, and λ represents the temperature attenuation adjustment coefficient, which can be taken as 1.1 here.

[0157] Since the basic real-time air temperature, basic real-time air pressure and basic real-time air humidity of the first target area and the second target area in the outdoor box are substantially the same, the dew point temperature of the first target area and the dew point temperature of the second target area can be considered equivalent.

[0158] By calculating the total condensation probability index of each ventilation path through the above formula, the best one can be quickly and accurately selected from multiple ventilation paths according to the total condensation probability index, and then the overall anti-condensation operation can be performed on multiple different target areas in the outdoor box to improve the overall anti-condensation effect.

To make the description concise, not all possible combinations of the technical features in the above-described embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0160] The above-mentioned embodiments only express several implementation methods of the present invention, and the descriptions thereof are relatively specific and detailed, but they cannot be understood as limiting the scope of the invention patent. It should be pointed out that, for ordinary technicians in this field, several variations and improvements can be made without departing from the concept of the present invention, and these all belong to the protection scope of the present invention.
