Description

Technical Field

[0001] This specification relates to the technical field of power plant equipment, and particularly to an outdoor distribution box. Background Art

[0002] In the outdoor environment of a power plant, distribution box equipment is often installed and used. However, due to the influence of the external environment, the humidity and temperature inside the distribution box often become abnormal, affecting the safe operation and service life of the distribution box.

[0003] Specifically, for example, in spring, due to the excessive humidity of the external environment, the humidity inside the distribution box is also relatively high. Excessive humidity will reduce the insulation strength of the components inside the distribution box. On the one hand, it will reduce the insulation performance of the air inside the distribution box, and many switch components in the distribution box rely on air gaps for insulation. On the other hand, it will also cause moisture in the air to adhere to the surface of the insulation materials of the components, reducing the insulation resistance of the relevant components. Especially for equipment components with a longer service life, due to the accumulation of dust inside, moisture is adsorbed, resulting in a more serious degree of dampness and a lower insulation resistance, increasing the leakage current of the equipment components and even possibly causing insulation breakdown and safety accidents.

[0004] Again, for example, in summer, due to the excessive temperature of the external environment, the temperature inside the distribution box is also relatively high. Excessive temperature will cause the aging and thermal failure of the insulation materials of components such as switches and cables inside the distribution box, accelerating the aging of the equipment components and even triggering faults of the equipment components.

[0005] Once again, for example, in winter, due to the excessively low temperature of the external environment, the temperature inside the distribution box is relatively low, for example, as low as 5°C. At this time, condensation is likely to occur in the equipment components inside the distribution box, resulting in a reduction in insulation resistance and thus prone to faults such as short circuits, grounding, and insulation breakdown.

[0006] For the above problems, the existing distribution boxes cannot effectively solve them. Utility Model Content

[0035] In order to enable those skilled in the art to better understand the technical solutions in this application, the technical solutions in the embodiments of this application will be clearly and completely described below in conjunction with the accompanying drawings in the embodiments of this application. Obviously, the described embodiments are only a part of the embodiments of this application, rather than all of the embodiments. Based on the embodiments in this application, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of this application.

[0036] Refer to Figure 1 As shown, an outdoor distribution box provided in this specification, specifically in implementation, may at least include: a housing, and a distribution box main body, a first fan, a second fan, and a heater disposed inside the housing; where

[0037] The first fan is disposed at the air inlet; the second fan is disposed at the air outlet; the air inlet is disposed at a lower position on one side of the housing; the air outlet is disposed at an upper position on the other side of the housing;

[0038] The first fan, the second fan, and the heater are respectively connected to a temperature control circuit and a humidity control circuit; the temperature control circuit and the humidity control circuit are connected to the main circuit of the distribution box main body;

[0039] The humidity control circuit at least includes a humidity-sensitive resistor switch; the temperature control circuit at least includes a thermistor switch; the humidity-sensitive resistor switch is disposed within a first adjacent range of the main body of the distribution box; the thermistor switch is disposed within a second adjacent range of the main body of the distribution box.

[0040] Among them, the main body of the distribution box is the core component that mainly works in the outdoor distribution box. The main body of the distribution box is connected to the main circuit. The main circuit provides the electric energy required for the operation of the main body of the distribution box.

[0041] Specifically, the first fan disposed at the air inlet is used to draw in cold air from the external environment. The second fan disposed at the air outlet is used to discharge the hot air inside the housing to the external environment. The first fan and the second fan can specifically be axial fans.

[0042] Specifically, the air inlet is arranged at a lower position on one side of the housing (for example, the left side of the housing), considering that cold air is usually heavier than hot air. The first fan at the air inlet disposed at the lower position can preferentially draw in relatively colder cold air from the external environment, thereby more effectively reducing the temperature inside the housing.

[0043] At the same time, the air outlet is arranged at an upper position on the other side of the housing (for example, the right side of the object), considering that hot air is usually lighter than cold air. The second fan at the air outlet disposed at the upper position can preferentially discharge the relatively hotter hot air inside the housing to the external environment, thereby more effectively reducing the temperature inside the housing.

[0044] Specifically, the above heater is used to heat the inside of the housing so that the moisture inside the housing (for example, the moisture carried by the air inside the housing, etc.) is heated and converted into water vapor; and then cooperate with the second fan to discharge it from the housing, thereby effectively reducing the humidity inside the housing.

[0045] Specifically, the above outdoor distribution box may specifically further include a temperature control circuit and a humidity control circuit.

[0046] Among them, the above temperature control circuit is specifically used to adjust and control the temperature inside the distribution box so that the internal temperature of the distribution box is less than or equal to the first temperature threshold and greater than or equal to the second temperature threshold, and is maintained within a suitable temperature range.

[0047] The above humidity control circuit is specifically used to adjust and control the humidity inside the distribution box so that the internal humidity of the distribution box is less than or equal to the preset humidity threshold and is maintained within a suitable humidity range.

[0048] Specifically, the above first fan, second fan, and heater are respectively connected to the temperature control circuit and the humidity control circuit. Among them, the temperature control circuit at least includes a thermistor switch, and the humidity control circuit at least includes a humidity-sensitive resistor switch.

[0049] Specifically, the above-mentioned thermistor switch is arranged within the first adjacent range of the distribution box main body (for example, the range with a distance less than or equal to 0.1 meter from the distribution box main body), and is used to monitor the temperature of the distribution box main body or the area near the distribution box main body. When it is detected that the temperature of the distribution box main body is too high (for example, greater than the first temperature threshold) or too low (for example, less than the second temperature threshold), affecting the normal operation of the distribution box main body, the switch automatically closes, conducts the temperature control circuit, and controls the operation of one or more of the first fan, the second fan, and the heater through the temperature control circuit, so that the temperature inside the distribution box is maintained within a suitable temperature range (for example, less than or equal to the first temperature threshold and greater than or equal to the second temperature threshold), to ensure the normal operation of the distribution box main body.

[0050] The above-mentioned humidity-sensitive resistor switch is arranged within the second adjacent range of the distribution box main body (for example, the range with a distance less than or equal to 0.5 meter from the distribution box main body), and is used to monitor the humidity of the distribution box main body or the area near the distribution box main body. When it is detected that the humidity of the distribution box main body is too high (for example, greater than the preset humidity threshold), affecting the normal operation of the distribution box main body, the switch automatically closes, conducts the humidity control circuit, and controls the operation of one or more of the first fan, the second fan, and the heater through the humidity control circuit, so that the humidity inside the distribution box is maintained within a suitable humidity range (for example, less than or equal to the humidity threshold), to ensure the normal operation of the distribution box main body.

[0051] During specific implementation, for example, when the humidity-sensitive resistor switch detects that the internal humidity is greater than the preset humidity threshold, the switch automatically closes, conducts the humidity control circuit, and automatically performs dehumidification processing. Specifically, the heater is controlled to operate through the humidity control circuit to heat up the inside of the distribution box, so as to convert the internal moisture into water vapor; at the same time, the second fan is controlled to operate to discharge the water vapor outside the housing, thereby reducing the humidity inside the distribution box. In addition, the humidity-sensitive resistor switch continuously monitors the internal humidity. When it is detected that the humidity is less than or equal to the preset humidity threshold, the switch automatically disconnects, the humidity control circuit disconnects, and the dehumidification processing automatically stops.

[0052] Also, for example, when the thermistor switch detects that the internal temperature is greater than the first temperature threshold, the switch automatically closes, conducts the temperature control circuit, and automatically performs cooling processing. Specifically, based on the cooling rule, the first fan is controlled to operate through the temperature control circuit to inhale relatively cold air from the external environment; at the same time, the second fan is controlled to operate to discharge the relatively hot air with a higher internal temperature to the external environment, thereby reducing the temperature inside the distribution box. In addition, the thermistor switch continuously monitors the internal temperature. When it is detected that the temperature is less than or equal to the first temperature threshold, the switch automatically disconnects, the temperature control circuit disconnects, and the cooling processing automatically stops.

[0053] For another example, when the thermistor switch monitors that the internal temperature is less than the second temperature threshold, the switch automatically closes, conducts the temperature control circuit, and automatically performs a heating process. Specifically, based on the heating rule, the heater is controlled by the temperature control circuit to increase the internal temperature of the distribution box. In addition, the thermistor switch continuously monitors the internal temperature. When the monitored temperature is greater than or equal to the second temperature threshold, the switch automatically disconnects, the temperature control circuit is disconnected, and the heating process automatically stops.

[0054] Based on the outdoor distribution box with the above structure, it can automatically monitor the humidity and temperature of the distribution box body inside the housing, and timely control the operation of the first fan, the second fan, and the heater through the humidity control circuit and / or the temperature control circuit when needed, so as to automatically maintain the temperature and humidity inside the outdoor distribution box within a suitable numerical range, ensure the safe and stable operation of the distribution box body, and better adapt to the complex and changeable outdoor environmental scenarios.

[0055] In some embodiments, the humidity control circuit and the temperature control circuit are respectively connected to the main circuit through a control transformer.

[0056] Specifically, the 220V power supply led out from the main circuit can be voltage-transformed by the control transformer to obtain a suitable voltage (for example, 12V voltage), and then provided to the humidity control circuit and the temperature control circuit for use respectively.

[0057] Based on the above structure, there is no need to additionally set up and use other power supplies, and the power supplies of the main circuit can be conveniently used to supply energy to the humidity control circuit and the temperature control circuit.

[0058] In some embodiments, a linkage circuit can also be provided between the humidity control circuit and the temperature control circuit.

[0059] Based on the above structure, by introducing and using the linkage circuit, in some cases, the temperature control circuit and the humidity control circuit can be simultaneously conducted to control the operation of the first fan, the second fan, and the heater by combining the temperature control circuit and the humidity control circuit, so as to more effectively maintain the temperature and humidity inside the distribution box within a suitable range.

[0060] In some embodiments, the above outdoor distribution box may further include: a processor. Wherein, the processor is respectively connected to the thermistor switch, the temperature control circuit, the humidity-sensitive resistor switch, and the humidity control circuit.

[0061] The above processor can monitor and determine the specific conditions of the temperature and humidity inside the distribution box according to the closing conditions of the thermistor switch and the thermistor switch; furthermore, according to the specific conditions of the temperature and humidity inside the distribution box, based on the corresponding regulation rules, the temperature control circuit and / or the humidity control circuit can be finely regulated, so as to more precisely adjust and control the temperature and humidity inside the distribution box through the regulated temperature control circuit and / or humidity control circuit.

[0062] Based on the above structure, by introducing and using a processor, the temperature and humidity inside the distribution box can be regulated more accurately and effectively.

[0063] In some embodiments, the heater may specifically include: a first heater and a second heater;

[0064] Among them, the first heater is arranged at the middle position on one side of the housing, and the second heater is arranged at the middle position on the other side of the housing.

[0065] Based on the above structure, by introducing two heaters, namely the first heater and the second heater, and distributing the two heaters at the middle positions on both sides of the housing, the air on the left side, right side, upper side and lower side of the housing can be heated simultaneously, obtaining a relatively better heating effect.

[0066] In some embodiments, rainproof edges are provided at positions adjacent to the upper sides of the air inlet and the air outlet outside the housing.

[0067] Based on the above structure, by introducing and using the rainproof edges, rainwater can be effectively prevented from flowing into the first fan and the second fan through the air inlet and the air outlet, protecting the first fan and the second fan.

[0068] In some embodiments, referring to Figure 2 , Figure 3 , Figure 4 As shown, ventilation windows are respectively provided at the air outlet and the air inlet. Among them, a plurality of baffles are equidistantly arranged in the ventilation windows.

[0069] Based on the above structure, by introducing and using the ventilation windows, while facilitating the inhalation or discharge of air from the external environment, it can effectively prevent animals such as insects in the external environment from entering the distribution box through the air inlet and the air outlet, affecting the operation of the distribution box main body, and thus can better protect the operation safety of the distribution box main body.

[0070] In some embodiments, referring to Figure 3 and Figure 5 As shown, a display panel is provided on the front of the housing outside;

[0071] Among them, the display panel at least includes a temperature control indicator light and a humidity control indicator light. The above display panel can be specifically arranged on the front of the housing.

[0072] Based on the above structure, by introducing and using the temperature control indicator light and the humidity control indicator light, the operating states of the temperature control circuit and the humidity control circuit can be more intuitively represented to the user.

[0073] In some embodiments, referring toFigure 5 As shown, the temperature control indicator lights may specifically include: a temperature control stop indicator light and a temperature control operation indicator light; the humidity control indicator lights include: a humidity control stop indicator light and a humidity control operation indicator light;

[0074] Among them, the temperature control stop indicator light and the temperature control operation indicator light are connected to the temperature control circuit, and the humidity control stop indicator light and the humidity control operation indicator light are connected to the humidity control circuit.

[0075] During specific implementation, when the temperature control circuit is turned on, the temperature control stop indicator light goes out and the temperature control operation indicator light lights up; when the temperature control circuit is turned off, the temperature control stop indicator light lights up and the temperature control operation indicator light goes out.

[0076] Similarly, when the humidity control circuit is turned on, the humidity control stop indicator light goes out and the humidity control operation indicator light lights up; when the humidity control circuit is turned off, the humidity control stop indicator light lights up and the humidity control operation indicator light goes out.

[0077] Based on the above structure, the specific operating states of the temperature control circuit and the humidity control circuit can be more precisely represented to the user (for example, the operation and maintenance personnel of the distribution box).

[0078] In some embodiments, referring to Figure 5 As shown, the display panel may further include: a temperature control manual / automatic conversion handle, a temperature manual control stop button, and a temperature manual control start button;

[0079] Among them, the temperature control manual / automatic conversion handle, the temperature manual control stop button, and the temperature manual control start button are connected to the temperature control circuit.

[0080] During specific implementation, when the user wants to manually control the temperature control circuit, the temperature control manual / automatic conversion handle on the display panel can be operated to adjust the temperature control circuit, which is originally in the default automatic mode, to the manual mode. In the manual mode, the user can flexibly cut off the temperature control circuit manually or turn on the temperature control circuit manually by operating the temperature manual control stop button or the temperature manual control start button on the display panel according to the specific situation, so as to achieve manual control of the temperature control circuit.

[0081] Based on the above structure, it can support the user to manually control the temperature control circuit manually by operating on the display panel when needed, meeting the diverse scenario requirements.

[0082] In some embodiments, referring to Figure 5 As shown, the display panel may further include: a humidity control manual / automatic conversion handle, a humidity manual control stop button, and a humidity manual control start button;

[0083] Among them, the humidity control manual-automatic conversion handle, the humidity manual control stop button, and the humidity manual control start button are connected to the humidity control circuit.

[0084] During specific implementation, when a user wants to manually control the humidity control circuit, they can operate the humidity control manual-automatic conversion handle on the display panel to adjust the humidity control circuit, which is originally in the default automatic mode, to the manual mode. In the manual mode, the user can, according to specific circumstances, flexibly cut off the humidity control circuit manually by operating the humidity manual control stop button on the display panel, or turn on the humidity control circuit manually by operating the humidity manual control start button, so as to achieve manual control of the humidity control circuit.

[0085] Based on the above structure, it can support users to manually control the humidity control circuit manually through operations on the display panel when needed, meeting the diverse scenario requirements.

[0086] In some embodiments, referring to Figure 5 As shown, the display panel may further include: an audible and visual alarm; wherein, the audible and visual alarm is connected to the humidity control circuit and the temperature control circuit.

[0087] Specifically, when the temperature inside the distribution box is too high, too low, or the humidity is too high, the humidity control circuit is turned on, or the temperature control circuit is turned on. At this time, the audible and visual alarm is powered on. Correspondingly, the audible and visual alarm can emit a warning sound or warning light (for example, an audible and visual alarm signal) to timely prompt the user that the current temperature and / or humidity inside the distribution box exceeds the safe range, so that the user can pay attention in time and strengthen patrol and maintenance. Thus, the operation safety of the outdoor distribution box can be better protected.

[0088] In some embodiments, the display panel may also be provided with an abnormal warning light. Among them, the abnormal warning light is connected to the processor. After the processor monitors that after a specified duration (for example, 1 hour) of corresponding regulation and control processing through the temperature control circuit and / or the humidity control circuit, the above temperature control circuit and / or humidity control circuit is still in the on state, it is judged that the temperature and / or humidity inside the distribution box is probably unable to be automatically regulated and restored to the safe range. At this time, the abnormal warning light can be lit to timely remind the user to perform manual intervention processing.

[0089] In some embodiments, the above thermistor switch may specifically include: a first thermistor switch and a second thermistor switch. Among them, the first thermistor switch corresponds to a second temperature threshold, and the second thermistor switch corresponds to a first temperature threshold.

[0090] Specifically, when the temperature is greater than the first temperature threshold, the second thermistor switch acts, closes the switch, and turns on the circuit where it is located. When the temperature is less than the second temperature threshold, the first thermistor switch acts, closes the switch, and turns on the circuit where it is located.

[0091] Further, the above temperature control circuit may specifically include a first sub-circuit and a second sub-circuit. Among them, the first sub-circuit at least includes a first thermistor, and the second sub-circuit at least includes a second thermistor. The above first sub-circuit and the second sub-circuit are independent of each other and are connected into the temperature control circuit. The above second sub-circuit is connected in series with the first fan and the second fan in the temperature control circuit. The above first sub-circuit is connected in series with the heater in the temperature control circuit.

[0092] Specifically, when the temperature is greater than the first temperature threshold, the second thermistor switch closes, turning on the second sub-circuit; further, the first fan and the second fan in the temperature control circuit can be powered on through the turned-on second sub-circuit, and the first fan and the second fan can be controlled to operate for temperature reduction. When the temperature is less than or equal to the first temperature threshold, the second thermistor switch opens, the second sub-circuit is correspondingly disconnected, the power supply to the first fan and the second fan is stopped, and further the temperature reduction process is stopped.

[0093] When the temperature is less than the second temperature threshold, the first thermistor switch closes, turning on the first sub-circuit; further, the heater in the temperature control circuit can be powered on through the turned-on first sub-circuit; and the heater can be controlled to operate for temperature increase. When the temperature is greater than or equal to the second temperature threshold, the first thermistor switch opens, the first sub-circuit is correspondingly disconnected, the power supply to the heater is stopped, and further the temperature increase process is stopped.

[0094] In some embodiments, a temperature sensor and a humidity sensor may also be provided at a position in the housing close to the main body of the distribution box; the above display panel is also provided with an information display screen; among them, the information display screen is connected to the temperature sensor and the humidity sensor. Correspondingly, the display panel can display the temperature and humidity inside the distribution box monitored in real time to the user through the information display screen, so that the user can timely understand the latest temperature and humidity conditions inside the distribution box.

[0095] In some embodiments, the above temperature control circuit may specifically refer to Figure 6 as shown.

[0096] In Figure 6 in order to simplify the description, an icon M is used to represent two fans, namely the first fan and the second fan. Among them, N represents the neutral line in the main circuit, and L represents the live line in the main circuit.

[0097] Referring to Figure 6 as shown, in addition to the thermistor switch (RT), the above temperature control circuit may further include: a temperature control operation indicator light (D1), a temperature control stop indicator light (D2), a control transformer (TC), a temperature control manual / automatic conversion handle (SA), a temperature manual control start button (SB1), a temperature manual control stop button (SB2), a heater (R), and an audible and visual alarm (BSG).

[0098] Specifically, the thermistor switches included in the temperature control circuit may include two thermistor switches: the first thermistor switch RT1 and the second thermistor switch RT2. Among them, the above RT1 corresponds to the second temperature threshold, and the above RT2 corresponds to the first temperature threshold.

[0099] And the above temperature control circuit further includes: a first sub-circuit containing RT1 and a second sub-circuit containing RT2.

[0100] Among them, when the temperature inside the distribution box is greater than the first temperature threshold, RT2 closes and the second sub-circuit conducts; at this time, the temperature control circuit mainly relies on the second sub-circuit to complete the corresponding cooling process.

[0101] When the temperature inside the distribution box is less than the second temperature threshold, RT1 closes and the first sub-circuit conducts; at this time, the temperature control circuit mainly relies on the first sub-circuit to complete the corresponding heating process.

[0102] In addition, the above temperature control circuit may further include: AC contactors KM1, KM2, KM3, and main power switch QF, heater power switch QF1, and fan power switch QF2.

[0103] Based on the above temperature control circuit, in specific implementation, when the temperature inside the distribution box is greater than the first temperature threshold, the second thermistor switch RT2 operates, attracts electricity and becomes charged; the coil of the AC contactor KM2 is charged and attracts; the sound and light alarm BSG is charged and operates to emit sound and light alarms. At the same time, the normally open contacts of the AC contactor KM2 close, and the fan M (including the first fan and the second fan) is charged and starts, sucking out the hot air inside the distribution box and discharging it out of the distribution box, and sending in the cold air from the external environment for cooling treatment.

[0104] When the temperature inside the current distribution box drops below and is equal to the first temperature threshold, the second thermistor switch RT2 resets; the coil of the AC contactor KM2 is powered off and disconnected; the sound and light alarm BSG is powered off; at the same time, the fan M stops running.

[0105] When the temperature inside the distribution box is less than the second temperature threshold, the first thermistor switch RT1 operates, attracts electricity and becomes charged; the coil of the AC contactor KM1 is charged and attracts; the sound and light alarm BSG is charged and operates to emit sound and light alarms. At the same time, the normally open contacts of the AC contactor KM1 close, and the heater R is powered on to work, heating the distribution box for heating treatment.

[0106] When the temperature inside the distribution box rises above and is equal to the second temperature threshold, the first thermistor switch RT1 resets; the coil of the AC contactor KM1 is powered off and disconnected, and the sound and light alarm BSG is powered off; at the same time, the heater R stops running.

[0107] Based on the above temperature control circuit, it can effectively perform corresponding cooling or heating treatment on the inside of the distribution box.

[0108] In some embodiments, the above-mentioned humidity control circuit can be specifically referred to Figure 7 as shown.

[0109] In Figure 7 , for the sake of simplicity of expression, an icon M is used to represent two fans, namely the first fan and the second fan. Among them, N represents the neutral wire in the main circuit, and L represents the live wire in the main circuit.

[0110] Referring to Figure 7 as shown, in addition to the humidity-sensitive resistor switch (H), the above-mentioned humidity control circuit may further include: a humidity control operation indicator light (D1), a humidity control stop indicator light (D2), a control transformer (TC), a humidity control manual-automatic conversion handle (SA), a humidity manual control start button (SB1), a humidity manual control stop button (SB2), a heater (R), and an audible and visual alarm (BSG).

[0111] In addition, the above-mentioned humidity control circuit may further include: AC contactors KM1, KM2, KM3, and a main power switch QF, a heater power switch QF1, and a fan power switch QF2.

[0112] Based on the above-mentioned humidity control circuit, in specific implementation, when the humidity inside the distribution box is greater than the preset humidity threshold, the humidity-sensitive resistor switch H acts and is energized and closed; the coil of the AC contactor KM3 is energized and closed; the audible and visual alarm BSG is energized and acts to give an audible and visual alarm. At the same time, the normally open contact of the AC contactor KM3 is closed, the heater R is energized and operates to heat the distribution box, heating the air containing moisture inside the distribution box; at the same time, the fan M starts to extract and discharge the moisture (for example, water vapor) generated by heating from the distribution box for dehumidification treatment.

[0113] When the humidity inside the distribution box drops to be less than or equal to the preset humidity threshold, the humidity-sensitive resistor switch H resets, the coil of the AC contactor KM3 is de-energized and opened, the audible and visual alarm BSG is de-energized, and the heater R and the fan M stop operating.

[0114] Based on the above-mentioned humidity control circuit, the inside of the distribution box can be effectively dehumidified accordingly.

[0115] In a specific scenario example, the outdoor distribution box provided in this specification can be used to automatically control and alarm the temperature and humidity of the distribution box in a power plant. The specific implementation process may include the following content.

[0116] In specific implementation, 220V power can be led from the lower port of the distribution box incoming line (main circuit) switch to the control transformer to step down the voltage to 12V. Then, the control transformer is connected to the humidity-sensitive resistor switch and the thermistor switch; among them, the switch load end can be connected to the heater and the fan.

[0117] When the environmental humidity reaches the set upper limit (e.g., a preset humidity threshold), the humidity-sensitive resistor switch operates, the audible and visual alarm operates to give an audible and visual alarm, the heater starts to heat the moisture; at the same time, the fan starts to extract the heated moisture from the distribution box. When the environmental humidity drops below the set upper limit, the humidity-sensitive resistor switch resets, the audible and visual alarm is powered off, and the dehumidification circuit (e.g., the humidity control circuit) stops operating.

[0118] When the environmental temperature reaches the set upper limit (e.g., the first temperature threshold), the thermistor switch operates, the audible and visual alarm operates to give an audible and visual alarm, the upper and lower fans in the distribution box (e.g., the first fan, the second fan) start to extract the hot air in the distribution box and send in cold air. After the environmental temperature drops below the set upper limit, the thermistor switch resets, the audible and visual alarm is powered off, and the cooling circuit (e.g., the temperature control circuit) stops operating.

[0119] When the environmental temperature drops below the set lower limit (e.g., the second temperature threshold), the thermistor switch operates, the audible and visual alarm operates to give an audible and visual alarm, the heater starts to heat the distribution box. When the temperature exceeds the set lower limit, the thermistor switch resets, the audible and visual alarm is powered off, and the heating circuit (e.g., the temperature control circuit) stops operating.

[0120] Thus, the above structure can ensure that the temperature and humidity in the outdoor distribution box are within the normal range, ensuring the safe and stable operation of electrical equipment.

[0121] Through the above scenario examples, it is verified that an outdoor distribution box provided in this specification has the following advantages: 1) Integrating the automatic control of temperature and humidity together reduces the increase in the number of devices caused by separately setting the corresponding device controls; 2) It does not require manual operation by the user, and automatically starts and stops through sensors, achieving high efficiency, speed, and accuracy, and also simplifies the user's operation; 3) Adding extraction and supply fans speeds up air circulation, quickly dehumidifies and cools, and reduces the risk of equipment water ingress; 4) Adding the function of alarming when the temperature and humidity exceed the limit reminds personnel that the temperature and humidity status in the distribution box is abnormal.
