[0004] However, when moisture-proofing is performed in the above manner, when the temperature is low, condensation in the box freezes and the dehumidification effect of the exhaust fan is poor. Utility Model Content

[0005] The present application provides a moisture-proof box transformer, which is used to solve the problem that the prior art only uses fans for dehumidification, and when the temperature is low, condensation in the box freezes and the dehumidification effect is poor.

[0006] The present application provides a moisture-proof box transformer, comprising a box body, a controller, a temperature sensor, a humidity sensor, a heater and a fan;

[0007] The box is used to be arranged above the cable well, and the fan is arranged on a side of the box away from the cable well;

[0008] The temperature sensor is used to monitor the temperature inside the box, and the humidity sensor is used to monitor the humidity inside the box;

[0010] The controller is configured to control the fan to turn on when the humidity inside the box is greater than or equal to a preset humidity value and the temperature inside the box is greater than or equal to a first preset temperature value;

[0011] The controller is also configured to control the heater and the fan to turn on simultaneously when the humidity inside the box is greater than or equal to a preset humidity value and the temperature inside the box is less than a first preset temperature value.

[0012] In one possible implementation, the moisture-proof box transformer provided in the present application also includes a ventilation duct, which is arranged on a side of the box body opposite to the cable well, and the ventilation duct is connected to the interior of the box body, and a fan is arranged at the connection point between the box body and the ventilation duct.

[0013] In a possible implementation, in the moisture-proof box-type transformer provided in the present application, a side of the ventilation duct facing away from the box body is closed, and a ventilation hole is provided on a side wall of the ventilation duct.

[0014] In a possible implementation, the moisture-proof box transformer provided in the present application further includes a first dustproof plate, and the first dustproof plate is arranged at the connection point between the ventilation duct and the box body.

[0015] In a possible implementation, the moisture-proof box transformer provided in the present application further includes a second dustproof plate, and the second dustproof plate is arranged at the ventilation opening.

[0016] In a possible implementation, in the moisture-proof box transformer provided by the present application, at least one of the first dustproof plate and the second dustproof plate is in a grid shape.

[0017] In one possible implementation, the moisture-proof box transformer provided in the present application has a controller configured to control the fan to turn on when the temperature inside the box is greater than or equal to a second temperature preset value, and the second temperature preset value is greater than the first temperature preset value.

[0018] In one possible implementation, the moisture-proof box transformer provided in the present application also includes a display screen arranged on the outer wall of the box body, and the display screen is electrically connected to the temperature sensor and the humidity sensor to display the temperature detected by the temperature sensor and the humidity detected by the humidity sensor.

When the humidity in the box is greater than or equal to the humidity preset value, and the temperature in the box is less than the first temperature preset value, it proves that the condensation inside the box is likely to freeze, so the controller needs to control the heater to turn on to melt the ice, and turn on the fan at the same time to discharge the melted water through the fan to achieve the dehumidification effect; when the humidity in the box is greater than or equal to the humidity preset value, and the temperature in the box is greater than or equal to the first temperature preset value, it proves that the water inside the box is in liquid or gas state, and no heating is required. The controller only needs to control the fan to turn on for dehumidification.

[0038] The above drawings have shown clear embodiments of the present application, which will be described in more detail later. These drawings and text descriptions are not intended to limit the scope of the present application in any way, but to illustrate the concept of the present application to those skilled in the art by referring to specific embodiments. DETAILED DESCRIPTION

[0039] Exemplary embodiments will be described in detail herein, examples of which are shown in the accompanying drawings. When the following description refers to the drawings, the same numbers in different drawings represent the same or similar elements unless otherwise indicated. The implementations described in the following exemplary embodiments do not represent all implementations consistent with the present application. Instead, they are merely examples of devices and methods consistent with some aspects of the present application as detailed in the appended claims.

[0040] As shown in the background technology, in the prior art, the moisture-proof measure for the box transformer is to install an exhaust fan on the box transformer. When the humidity inside the box is high, the staff turns on the exhaust fan for dehumidification. However, in such dehumidification, the condensation inside the box is easy to freeze in a low temperature environment, resulting in poor dehumidification effect of the exhaust fan.

[0041] In view of the above technical problems, the embodiment of the present application provides a moisture-proof box transformer, including a box, a controller, a temperature sensor, a humidity sensor, a heater and a fan. The fan is arranged on the side of the box away from the cable well, so that when the fan is turned on, the air inside the box forms effective convection and enhances the dehumidification effect. The temperature sensor detects the temperature inside the box, and the humidity sensor detects the humidity inside the box. When the humidity inside the box is greater than or equal to the humidity preset value, if the temperature inside the box is less than the first temperature preset value, the controller controls the heater to turn on to prevent condensation inside the box from freezing, and turns on the fan at the same time to dehumidify; if the temperature inside the box is greater than or equal to the first temperature preset value, the controller only controls the fan to turn on for dehumidification. In this way, in a low temperature environment, the temperature inside the box is increased by the heater to prevent condensation from freezing, so as to ensure the dehumidification effect of the fan, so that the moisture-proof box transformer can maintain a good dehumidification effect under different temperature conditions, thereby improving its applicability.

[0042] The following specific embodiments are used to describe in detail the technical solution of the present application and how the technical solution of the present application solves the above-mentioned technical problems. The following specific embodiments can be combined with each other, and the same or similar concepts or processes may not be repeated in some embodiments. The embodiments of the present application will be described below in conjunction with the accompanying drawings:

[0043] See also Figure 3 , Figure 4 and Figure 5 As shown, the moisture-proof box transformer of the embodiment of the present application includes a box body 100, a controller (not shown in the figure), a temperature sensor 200, a humidity sensor 300, a heater 400 and a fan 500; the box body 100 is used to be arranged above the cable well, and the fan 500 is arranged on the side of the box body 100 away from the cable well; the temperature sensor 200 is used to monitor the temperature inside the box body 100, and the humidity sensor 300 is used to monitor the humidity inside the box body 100; the temperature sensor 200, the humidity sensor 300 and the heater 400 are all arranged in the box body 100, the controller is electrically connected to the temperature sensor 200, the humidity sensor 300, the heater 400 and the fan 500; the controller is configured to control the fan 500 to turn on when the humidity inside the box 100 is greater than or equal to the humidity preset value, and the temperature inside the box 100 is greater than or equal to the first temperature preset value; the controller is also configured to control the heater 400 and the fan 500 to turn on at the same time when the humidity inside the box 100 is greater than or equal to the humidity preset value, and the temperature inside the box 100 is less than the first temperature preset value.

[0044] In the present application, the temperature sensor 200 and the humidity sensor 300 are both arranged in the box 100, and are used to detect the temperature and humidity inside the box 100. The humidity sensor 300 and the temperature sensor 200 are both electrically connected to the input end of the controller, and the detected temperature signal and humidity signal are transmitted to the controller. The fan 500 and the heater 400 are both electrically connected to the output end of the controller, and the controller controls the start or shut down of the fan 500 and the heater 400 according to the temperature signal and the humidity signal.

[0045] Specifically, when the humidity detected by the humidity sensor 300 is greater than or equal to the humidity preset value, if the temperature detected by the temperature sensor 200 is greater than or equal to the first temperature preset value, it proves that the water inside the box 100 is in liquid or gas state, and the controller only needs to control the fan 500 to start to achieve the dehumidification effect; if the temperature detected by the temperature sensor 200 is lower than the first temperature preset value, condensation and ice may occur inside the box 100. To ensure the dehumidification effect, the controller needs to turn on the fan 500 and the heater 400 at the same time, and use the heater 400 to increase the temperature inside the box 100 so that all the ice melts into water, and then dehumidifies through the fan 500, thereby ensuring the dehumidification effect of the moisture-proof box in a low temperature environment.

[0046] Among them, the humidity preset value and the first temperature preset value can be set according to actual conditions. The specific values ​​are not limited in this application, and it is sufficient to ensure that the electrical equipment inside the box 100 works normally.

[0047] In addition, the fan 500 is arranged on the side of the box 100 facing away from the cable well. This is beneficial for effective convection of air in the box 100 when the fan 500 is turned on, thereby achieving effective ventilation and enhancing the dehumidification effect.

[0048] In this way, the moisture-proof box transformer provided in this embodiment dehumidifies only through the fan 500 in a high temperature environment, and ensures the dehumidification effect through the cooperation of the heater 400 and the fan 500 in a low temperature environment, so that the moisture-proof box transformer can maintain a good dehumidification effect under various temperature conditions, thereby improving the applicability of the moisture-proof box transformer.

[0049] In some possible implementations, see Figure 1 , Figure 4 and Figure 5 As shown, the embodiment of the present application also includes a ventilation duct 600, which is arranged on a side of the box 100 opposite to the cable well, and the ventilation duct 600 is connected to the interior of the box 100, and the fan 500 is arranged at the connection point between the box 100 and the ventilation duct 600.

[0050] In some embodiments, a ventilation duct 600 is provided on the housing 100, and a fan 500 is provided at the connection point between the ventilation duct 600 and the housing 100. Exposing the fan 500 to the outside for a long time may cause damage to the fan 500 due to external environment such as strong winds. The ventilation duct 600 can protect the fan 500.

[0051] In addition, various forms of air outlets may be provided on the ventilation duct 600 to adjust the amount of air delivered by the fan 500, or facilities such as a muffler may be provided on the ventilation duct 600 to avoid excessive noise during the dehumidification process.

[0052] In some possible implementations, see Figure 2 and Figure 4 As shown, the ventilation duct 600 of the embodiment of the present application is closed on one side facing away from the box body 100 , and a ventilation hole is provided on the side wall of the ventilation duct 600 .

[0053] In a specific implementation, the ventilation duct 600 has a vent on its side wall, which is closed on the side facing away from the box body 100. Thus, the vent is perpendicular to the box body 100, which can prevent rain or snow from passing through the vent along the ventilation duct 600 into the box body 100 in rainy and snowy weather and causing damage to internal electrical equipment, thereby ensuring that the moisture-proof box transformer can operate normally in different weather conditions.

[0054] In some possible implementations, see Figure 2 and Figure 4 As shown, the embodiment of the present application further includes a first dustproof plate 610 , and the first dustproof plate 610 is arranged at the connection point between the ventilation duct 600 and the box body 100 .

[0055] Specifically, a first dustproof plate 610 is provided at the connection point between the ventilation duct 600 and the box body 100 to prevent dust in the air from entering the inside of the box body 100 along the ventilation duct 600 and affecting the heat dissipation of the electrical equipment in the box body 100.

[0056] In some possible implementations, see Figure 2 and Figure 4 As shown, the embodiment of the present application further includes a second dustproof plate 620, and the second dustproof plate 620 is arranged at the ventilation opening.

[0057] Furthermore, a second dustproof plate 620 is provided at the ventilation opening to prevent dust in the air from entering the ventilation duct 600 , thereby further enhancing the dustproof effect and ensuring the normal operation of the electrical equipment inside the box 100 .

[0058] In some possible implementations, see Figure 2 and Figure 4 As shown, at least one of the first dustproof plate 610 and the second dustproof plate 620 of the embodiment of the present application is in a grid shape.

[0059] It is understandable that the first dustproof plate 610 and the second dustproof plate 620 can be set in a grid shape, and the grid-shaped dustproof plate can also play a certain dust-proof role without affecting the ventilation effect.

[0060] In some possible implementations, see Figure 4 and Figure 5 As shown, the controller of the embodiment of the present application is also configured to control the fan 500 to turn on when the temperature inside the box 100 is greater than or equal to a second temperature preset value, and the second temperature preset value is greater than the first temperature preset value.

[0061] In a specific implementation, since electrical equipment generates heat when it is running, the temperature inside the box 100 is high in hot weather. Too high a temperature may affect the operating efficiency of the electrical equipment and may even cause malfunctions. Therefore, when the temperature sensor 200 detects that the temperature inside the box 100 is greater than or equal to the second temperature preset value, the controller controls the fan 500 to turn on for heat dissipation, so as to reduce the temperature inside the box 100 and avoid malfunctions of the electrical equipment.

[0062] It is understandable that, since the first temperature preset value is the temperature at which condensation in the box 100 may freeze, and the second temperature preset value is the temperature at which the electrical equipment in the box 100 may overheat, etc., affecting the normal operation of the electrical equipment, the second temperature preset value is greater than the first temperature preset value. The specific value of the second temperature preset value can be set according to the working environment requirements of the electrical equipment, and this application does not limit it.

[0063] In some possible implementations, see Figure 1 , Figure 4 and Figure 5 As shown, the embodiment of the present application also includes a display screen 700 arranged on the outer wall of the box body 100, and the display screen 700 is electrically connected to the temperature sensor 200 and the humidity sensor 300 to display the temperature detected by the temperature sensor 200 and the humidity detected by the humidity sensor 300.

[0064] It should be noted that the display screen 700 is set on the outer wall of the box 100, and is used to display the temperature and humidity detected by the humidity sensor 300 and the temperature sensor 200, so that on-site staff can check the temperature and humidity conditions inside the box 100 at any time, and can manually control the fan 500 or heater 400 to start according to actual needs for dehumidification or heat dissipation.

[0065] In some possible implementations, see Figure 5 As shown, an embodiment of the present application includes an alarm device, and a controller is communicatively connected to the alarm device (not shown in the figure). The controller is configured to control the alarm device to send an alarm signal when the humidity inside the box 100 is greater than or equal to a humidity preset value, or when the temperature inside the box 100 is greater than or equal to a second temperature preset value.

[0066] Specifically, by setting an alarm device, when the temperature or humidity inside the box 100 is too high, an alarm signal is issued so that the staff can promptly detect the abnormal situation inside the box 100 and take corresponding measures to further improve the safety of the operation of the moisture-proof box transformer.

[0067] Among them, the alarm device can be a physical device installed near the moisture-proof box, which transmits the alarm signal by lighting up a warning light or making a buzzing sound. It can also be a communication tool such as a staff member's mobile phone, which transmits the alarm signal by sending information to the communication tool. The specific type of the alarm device is not limited in this application, as long as it can enable the staff to promptly perceive the humidity and temperature conditions inside the box 100.

[0068] In some possible implementations, see Figure 4 As shown, the ventilation duct 600 of the embodiment of the present application is a galvanized steel pipe.

[0069] It can be understood that galvanized steel pipes have the characteristics of strong oxidation resistance and excellent corrosion resistance. The use of galvanized steel pipes for the ventilation duct 600 is beneficial to improving the service life of the ventilation duct 600.

[0070] In summary, the moisture-proof box transformer provided by the present application includes a box 100, a controller, a temperature sensor 200, a humidity sensor 300, a heater 400 and a fan 500. The temperature sensor 200, the humidity sensor 300 and the heater 400 are all arranged inside the box 100. When the humidity inside the box 100 is greater than or equal to the humidity preset value, if the temperature inside the box 100 is greater than or equal to the first temperature preset value, the controller only controls the fan 500 to start; if the temperature inside the box 100 is less than the first temperature preset value, the controller controls the fan 500 and the heater 400 to start at the same time, so as to avoid condensation and ice formation inside the box 100 and affect the dehumidification effect. In this way, the moisture-proof box transformer of the present application can increase the temperature inside the box 100 with the assistance of the heater 400 in a low temperature environment, melt the ice, and ensure the dehumidification effect of the fan 500, so that the moisture-proof box transformer can maintain a good dehumidification effect under different temperature conditions, and has strong applicability.
