Description

Technical Field

[0001] The present invention relates to the technical field of outdoor boxes, and in particular, to a dew-proof outdoor box, a control method and device for a dew-proof outdoor box. 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, it is easy to cause dew condensation inside the outdoor box. Especially in coastal areas, as well as in the northeast and northwest regions, due to reasons such as high humidity or large day-night temperature differences, dew condensation is more likely to form. The dew condensation phenomenon can cause surface corrosion of electrical equipment, reduce insulation performance, generate flashover and creepage phenomena, and even cause short-circuit phenomena. Electrical components operating in a high-humidity environment for a long time will shorten the service life of the electrical appliances. Especially when the dew drops on the top cover drip onto the live components, it will cause a short circuit and even trigger a fire, which poses a great hazard to the electrical box.

[0003] The Chinese invention patent with the application number CN201910895968.8 discloses a dew-proof 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 layer of the electrical box top cover is sprayed with a super-hydrophilic coating, and the contact angle of water droplets on the surface of the super-hydrophilic coating is less than 5°. When the water vapor in the box is saturated, the water vapor can also be completely wetted and spread out on its surface without condensing into particles to form dew condensation. This dew-proof structure for an outdoor electrical box only passively avoids the dew condensation formed on the inner wall of the top cover of the electrical box from dripping onto the surface of the electrical components through the top cover structure and spraying a super-hydrophilic coating on the inner wall of the top cover. It does not actively adjust the temperature difference between the inside and outside of the outdoor box by detecting the temperature and humidity changes inside the outdoor box, and cannot effectively avoid the generation of the dew condensation phenomenon, and the degree of intelligence is relatively low and needs to be improved.

[0056] Embodiment 1:

[0057] Most of the existing outdoor box housings are made of metal, and the heat transfer of metal is relatively fast. The temperature and humidity inside the outdoor box are easily affected by the outdoor environment. Especially in coastal areas, as well as in the northeast, northwest regions, due to reasons such as high humidity or large temperature differences between day and night, condensation is likely to form. The condensation phenomenon will cause surface corrosion of electrical equipment and deterioration or damage of the performance of electrical components. The existing anti-condensation structure of outdoor boxes passively avoids the condensation formed on the inner wall of the top cover of the electrical box from dripping onto the surface of electrical components through structural settings, such as applying a super-hydrophilic coating on the top cover. However, the condensation phenomenon will still occur due to the high air humidity and large temperature difference in the outdoor electrical box. Therefore, it is necessary to improve the outdoor box to actively avoid the generation of the condensation phenomenon in order to better ensure the safe and effective operation of electrical components.

[0058] In order to solve the problems existing in the existing anti-condensation structure of outdoor boxes, this embodiment provides an anti-condensation outdoor box, as Figure 1As shown in the figure, 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. An air inlet 4 and an air outlet 5 are provided on the housing. The electrical components include, but are not limited to, circuit breakers, disconnectors, instrumentation, terminal blocks, and busbars, etc.

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

[0060] The first data acquisition component is used to acquire first basic real-time data related to the dew point temperature in the first target area of 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 the first basic real-time air temperature, the first basic real-time air humidity, and the first basic real-time air pressure. 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 further includes an external air temperature sensor for acquiring the external air temperature of the outdoor box. The first basic real-time data further 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 the controller obtains the first basic real-time air temperature, the first basic real-time air humidity, and the first basic real-time air pressure, it can obtain the corresponding dew point temperature by querying the dew point temperature comparison table.

[0064] The difference between the first basic real-time air temperature and the dew point temperature represents the degree of air saturation.

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

[0066] The first real-time state 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 for adjusting the temperature of the first target area (such as a heating component or a cooling unit).

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

[0068] A preset saturation degree threshold is pre-stored in the controller. The purpose of generating a real-time adjustment action instruction when the air saturation degree is less than the preset saturation degree threshold is to adjust the temperature of the first target area or the air temperature 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 generation of condensation in the outdoor box, so as to better achieve the anti-condensation operation and improve the working performance and service 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 in the first target area of the outdoor box, calculates the air saturation degree of the first target area, generates a real-time adjustment action instruction when the air saturation degree is less than the preset saturation degree threshold, sends the instruction to the dew point adjustment component, and actively controls the dew point adjustment component to act according to the real-time adjustment action instruction to adjust the first real-time state data of the first target area, so as to achieve the anti-condensation operation, which can effectively avoid the generation of condensation and improve the intelligent degree of anti-condensation of the outdoor box.

[0070] Preferably, the controller includes a real-time instruction generation unit, a condensation probability calculation unit, and a preliminary instruction calculation unit.

[0071] The real-time instruction generation unit is used to generate a real-time adjustment action instruction when the air saturation degree is less than the preset saturation degree 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 the first basic historical temperature, humidity, and air pressure data. By constructing a neural network model and training the neural network model with the first basic historical data, the trained neural network model is used to calculate the 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 in the first target area, and TD1 represents the average value of the first basic predicted dew point temperature in the next preset time period in the first target area.

[0076] The next preset time period takes the current moment as the starting point of time and calculates the end point of time with the width of the preset time period.

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

[0078] Wherein, the dew point adjustment component is further 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 can be a standby state, that is, a low-speed operation state.

[0080] By obtaining the first basic historical data, obtaining the predicted condensation probability of the first target area according to the basic historical data and the first basic real-time data, and generating a preparatory adjustment action instruction when the predicted condensation probability is greater than the preset probability threshold and the air saturation degree is not less than the preset saturation degree threshold, 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, it is possible to make the dew point adjustment component prepare in advance when the outdoor box is in a normal state and condensation is likely to occur next, and then enter the preparatory state, which improves the response speed of anti-condensation and further improves the degree of intelligence.

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

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

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

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

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

[0087] By controlling the opening degree of the ventilation regulating valve by the controller, different ventilation paths can be selected as needed to ventilate the first target area and a plurality of second target areas, so as to reduce the temperature difference between the inside and outside of the outdoor box and avoid the occurrence of condensation, so as to perform an overall anti-condensation operation 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 in a plurality of second target areas in the outdoor box.

[0091] 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 the second basic real-time air temperature, the second basic real-time air humidity and the 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.

[0092] By setting multiple ventilation ducts, multiple different ventilation paths are formed inside the outdoor box. Calculate the total condensation probability index of each ventilation path, select the optimal one from the multiple ventilation paths according to the total condensation probability index, and generate a real-time adjustment action instruction according to the optimal ventilation path, which can perform the overall anti-condensation operation for multiple different target areas inside the outdoor box, improve the overall efficiency of anti-condensation in multiple different areas of the outdoor box, ensure the safety and stability of the operation of electrical components inside the outdoor box, and thus improve the service life of electrical components.

[0118] The bracket 6 is fixed on the side plate of the housing; the fan is fixedly installed on the bracket 6, and the inlet is communicated with the air inlet; the inlets of a plurality of ventilation ducts are communicated with the outlet of the fan, and a ventilation regulating valve is installed on each ventilation duct.

[0119] The ventilation regulating valve is signal-connected to the controller, and the controller controls the opening degree and the opening and closing of the ventilation regulating valve by sending command signals to the ventilation regulating valve.

[0120] Among them, a plurality of ventilation ducts form a plurality of different ventilation paths in the outdoor box.

[0121] Specifically, the ventilation ducts can be installed along the side plate of the housing, passing through the centers, edges or above of the first target area and a plurality of second target areas, and ventilation holes are opened on the side walls of the ventilation ducts facing the first target area and the second target areas. The paths of the plurality of ventilation ducts passing through the first target area and the plurality of second target areas are different to form a plurality of different ventilation paths. Of course, different ventilation paths can also be formed by setting the orientation angles of the ventilation ducts.

[0122] By controlling the opening degree of the ventilation regulating valve through the controller, different ventilation paths can be selected as needed to ventilate the first target area and a plurality of second target areas, so as to reduce the temperature difference between the inside and outside of the outdoor box and avoid the occurrence of condensation, so as to perform an overall anti-condensation operation on the outdoor box.

[0123] Preferably, a plurality of second data acquisition components are further 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 in a plurality of second target areas in the outdoor box.

[0125] The controller is further used to calculate the total condensation probability index of the first target area and the plurality of second target areas under each ventilation path according to the first basic real-time data and the second basic real-time data, select the optimal one from the plurality of ventilation paths according to the condensation probability total index, and generate a real-time adjustment action instruction according to 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 the second basic real-time air temperature, the second basic real-time air humidity and the 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 multiple ventilation ducts to form multiple different ventilation paths inside the outdoor box, calculating the total condensation probability index of each ventilation path, selecting the optimal one from multiple ventilation paths according to the total condensation probability index, and generating a real-time adjustment action instruction based on the optimal ventilation path, the overall anti-condensation operation can be carried out for multiple different target areas inside the outdoor box, 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 inside the outdoor box, and thus increasing the service life of electrical components.

[0129] This embodiment also provides an anti-condensation control method for an outdoor box, as Figure 3 shown, which includes the following steps:

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

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

[0132] S3, Respond to the real-time adjustment action instruction, and adjust the first real-time state data of the first target area inside the outdoor box to achieve the anti-condensation operation.

[0133] The anti-condensation control method for the outdoor box collects the first basic real-time data related to the dew point temperature in the first target area inside the outdoor box, calculates the air saturation degree 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 degree is less than the preset saturation degree threshold, and actively controls the dew point adjustment component to act according to the real-time adjustment action instruction to adjust the first real-time state data of the first target area, so as to achieve the anti-condensation operation, which can effectively avoid the generation of condensation phenomenon and improve the intelligent degree of anti-condensation of the outdoor box.

[0134] Preferably, as Figure 4 shown, the anti-condensation control method for the outdoor box further 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, Generate a preliminary adjustment action instruction when the predicted condensation probability is greater than the preset probability threshold and the air saturation degree is not less than the preset saturation degree threshold.

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

[0138] By obtaining the first basic historical data, the predicted condensation probability of the first target area is obtained based on the basic historical data and the first basic real-time data. When the predicted condensation probability is greater than the preset probability threshold and the air saturation degree is not less than the preset saturation degree threshold, a preliminary adjustment action instruction is generated, so that the dew point adjustment component responds to the preliminary adjustment action instruction and enters a preliminary state matching the preliminary 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 enter the preliminary state, improving the response speed of anti-condensation and further enhancing the degree of intelligence.

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

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

[0143] S9. Select the optimal one from 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 degree is less than the preset saturation degree threshold includes: S10. When the air saturation degree is less than the preset saturation degree threshold, generate a real-time adjustment action instruction according to the optimal ventilation path.

[0145] By setting multiple ventilation ducts to form multiple different ventilation paths inside the outdoor box, calculating the total condensation probability index of each ventilation path, selecting the optimal one from multiple ventilation paths according to the total condensation probability index, and generating a real-time adjustment action instruction according to the optimal ventilation path, the overall anti-condensation operation can be carried out for multiple different target areas inside the outdoor box, 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 inside the outdoor box, and thus improving the service life of electrical components.

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

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

[0148] A controller;

[0149] A memory storing executable instructions;

[0150] wherein the executable instructions can run on the controller and implement the anti-condensation outdoor box control method described above.

[0151] Embodiment III:

[0152] It should be understood that this embodiment includes all the technical features of the above embodiments and further elaborates 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 areas are the inner surfaces of the front, rear, left, and right four side plates of the outer shell, the inner diameter of the ventilation duct is between 1.5 CM and 2.5 CM, and the wall thickness is between 2 mm and 4 mm, which is made of plastic or rubber to ensure its air heat preservation performance.

[0154] The width range of the top cover is 1.0 M - 1.2 M, the length range is 1.5 M - 2.5 M, the length of the side plates is between 2 M and 3 M, the diameter of the ventilation holes is between 3 mm and 4 mm, and the ventilation duct is located above the first target area and the second target areas. The distance between the ventilation duct and the first target area and the second target areas is 5 - 8 mm. Each ventilation duct is of equal length and the length is not greater than 35 M. The number of ventilation holes on the ventilation duct corresponding to the first target area and each second target area is not greater than 3, and the fan wind speed is between 6.5 m / s and 10.9 m / s.

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

[0156] wherein, L represents the length of the ventilation duct, L1 represents the length of the duct from one of the ventilation holes corresponding to the first target area to the inlet of the ventilation duct, L 2irepresents the pipe length from one of the ventilation holes of the ventilation pipe corresponding to the i-th second target area to the inlet of the ventilation pipe, n represents the number of second target areas, T0 represents the external 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 take the value of 1.1 here.

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

[0158] By calculating the total condensation probability index of each of the ventilation paths through the above formula, the optimal one can be quickly and relatively accurately selected from multiple ventilation paths according to the total condensation probability index, and then the overall anti-condensation operation can be carried out for multiple different target areas in the outdoor box, improving the overall anti-condensation effect.

[0159] The technical features of the above-described embodiments can be combined arbitrarily. For the sake of brevity of description, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, it should be considered as the scope described in this specification.

[0160] The above-described embodiments only represent several implementation manners of the present invention, and their descriptions are relatively specific and detailed, but they should not be construed as limiting the scope of the invention patent. It should be noted that for those of ordinary skill in the art, without departing from the concept of the present invention, several deformations and improvements can still be made, and these all belong to the protection scope of the present invention. Therefore, the protection scope of the present invention patent should be subject to the appended claims.
