Description

TECHNICAL FIELD

[0001] The application relates to the technical field of low-voltage cabinet cooling, and in particular to a low-voltage cabinet cooling method and system, an intelligent terminal and a storage medium. BACKGROUND

[0002] A low-voltage cabinet is a key device in a low-voltage power distribution system and is mainly used for power distribution, control, protection and monitoring. Since a large amount of heat is generated in the low-voltage cabinet during operation, the operation of the low-voltage cabinet is affected. Therefore, the key measure to ensure the stable operation of the internal electrical elements of the low-voltage cabinet and prolong the service life of the device is to ensure the stable operation of the internal electrical elements of the low-voltage cabinet and prolong the service life of the device.

[0003] In the related art, the low-voltage cabinet is cooled by the cooperative operation of an air conditioner and a fan. On the one hand, the air conditioner is turned on to reduce the temperature of the environment in which the low-voltage cabinet is located. On the other hand, the bottom and the top of the low-voltage cabinet are provided with fans. The fan at the bottom is used for air intake, and the fan at the top is used for air exhaust. The external air enters the low-voltage cabinet from the bottom and leaves from the top, thereby achieving circulating heat dissipation.

[0004] In the related art, since there are many elements in the low-voltage cabinet, the elements not only block the flow of air but also heat the air during the upward movement of the air. As a result, the temperature of the air conducted to the upper part of the low-voltage cabinet is relatively high, which reduces the heat dissipation efficiency of the low-voltage cabinet. SUMMARY

[0005] In order to improve the heat dissipation efficiency of the low-voltage cabinet, the application provides a low-voltage cabinet cooling method, system, intelligent terminal and storage medium.

[0006] In a first aspect, the application provides a low-voltage cabinet cooling method, which adopts the following technical scheme:

[0007] A low-voltage cabinet cooling method, comprising:

[0008] monitoring the cabinet temperature and the cabinet temperature outside the low-voltage cabinet;

[0009] calculating the difference between the cabinet temperature and the cabinet temperature outside the low-voltage cabinet to obtain a temperature rise value;

[0010] if the cabinet temperature is greater than a first temperature threshold or the temperature rise value is greater than a second temperature threshold, an abnormal position corresponding to the cabinet temperature is obtained;

[0011] if the abnormal position is located at the bottom or the top of the low-voltage cabinet, a cooling device of the low-voltage cabinet is turned on. The cooling device comprises an air inlet assembly located at the bottom of the low-voltage cabinet and an air outlet assembly located at the top of the low-voltage cabinet. A plurality of accommodating cavities are arranged in the low-voltage cabinet. An auxiliary device is arranged in each accommodating cavity. The auxiliary device is close to a conduction channel in the low-voltage cabinet. The conduction channel penetrates through the accommodating cavities.

[0013] determining a target auxiliary device corresponding to the cavity number;

[0014] starting the cooling device and the target auxiliary device at the same time, so that the target auxiliary device sucks air from the conduction channel.

[0015] By using the above technical solution, whether the overheat phenomenon occurs in the low-voltage cabinet is determined by combining the temperature in the cabinet and the temperature rise value, and the abnormal position is determined after the overheat phenomenon occurs. If the abnormal position is in the middle of the low-voltage cabinet, the target auxiliary device and the conduction channel are used to realize cooling. Since the conduction channel penetrates the containing cavity, the temperature of the air flowing in the conduction channel is low, and when the target auxiliary device is used, it will suck air from the conduction channel, ensuring that the temperature of the air used for cooling is low, thereby improving the cooling efficiency of the low-voltage cabinet.

[0016] Optionally, in the case that there are two abnormal positions, a first abnormal position and a second abnormal position are determined;

[0022] By using the above technical solution, in the case that there are two abnormal positions, a first auxiliary device and a second auxiliary device are determined, and the working direction of the first auxiliary device swings between a first angle and a second angle, and the working direction of the second auxiliary device is controlled to align with the second abnormal position. The operation mode of the first auxiliary device not only can cool the two abnormal positions, but also can promote the air flow in the containing cavity, thereby improving the cooling efficiency of the low-voltage cabinet.

[0023] Optionally, the first abnormal position in the first cabinet temperature and the second abnormal position at the second cabinet temperature are monitored;

[0026] If the second cabinet temperature is greater than the first temperature threshold within a preset time, the working power of the first auxiliary device is reduced, and the working power of the second auxiliary device is increased.

[0027] By using the above technical scheme, when the first cabinet temperature at the first abnormal position is greater than the first temperature threshold, the working direction of the first auxiliary device is controlled to align with the first abnormal position, thereby ensuring the cooling effect of the first abnormal position. When the second cabinet temperature at the second abnormal position is greater than the first temperature threshold, the working direction of the first auxiliary device is controlled to align with the second abnormal position, and the working power of the second auxiliary device is increased when the first auxiliary device is closed within a preset time. The influence of the first auxiliary device on the air in the conduction channel is reduced, and the cooling effect of the second auxiliary device is ensured, thereby improving the cooling efficiency of the low-voltage cabinet.

[0028] Optionally, in response to detecting that the cabinet temperature is greater than a third temperature threshold, a lower auxiliary device of the target auxiliary device is determined, and the third temperature threshold is greater than the first temperature threshold;

[0029] According to the positional relationship between the abnormal position and the lower auxiliary device, a lower target direction is set;

[0030] According to the difference between the cabinet temperature and the first temperature threshold, the working power of the lower auxiliary device is set;

[0031] The lower auxiliary device is turned on according to the working power, and the lower auxiliary device is controlled to work towards the target direction.

[0032] By using the above technical scheme, when the cabinet temperature is greater than the third temperature threshold, the lower auxiliary device is turned on, and the lower auxiliary device is used to cool the abnormal position, thereby quickly reducing the temperature at the abnormal position and achieving rapid cooling of the low-voltage cabinet.

[0033] Optionally, the temperature in the conduction channel is monitored to obtain a conduction temperature;

[0034] In a case that the conduction temperature is greater than a fourth temperature threshold, a shielding auxiliary device is determined according to the target auxiliary device, and the shielding auxiliary device is located between the target auxiliary device and the air inlet assembly;

[0035] The shielding auxiliary device is started, and a working direction of the shielding auxiliary device is controlled to be a vertical upward direction;

[0036] A blocking auxiliary device is determined according to the target auxiliary device, and the blocking auxiliary device is located in an upper layer of a containing cavity in which the target auxiliary device is located;

[0037] The blocking auxiliary device is started, and a working direction of the blocking auxiliary device is controlled to be toward the conduction channel.

[0038] By using the above technical solution, if the temperature in the conduction channel is greater than the fourth temperature threshold, the shielding auxiliary device and the blocking auxiliary device are started, the working direction of the shielding auxiliary device is the vertical upward direction, and the working direction of the blocking auxiliary device is toward the conduction channel, so that an isolation zone is formed between the conduction channel and the containing cavity, and air with a lower temperature is directly sent to the target auxiliary device.

[0039] Optionally, the air outlet assembly includes a first air outlet subassembly and a second air outlet subassembly, the first air outlet subassembly is used for ventilating the containing cavity, and the second air outlet subassembly is used for ventilating the conduction channel;

[0040] A remaining auxiliary device is determined according to the shielding auxiliary device, and the remaining auxiliary device is located between the shielding auxiliary device and the air outlet assembly;

[0041] A remaining cabinet temperature corresponding to the remaining auxiliary device is obtained;

[0042] If a target remaining cabinet temperature greater than the first temperature threshold exists in the remaining cabinet temperature, a target remaining auxiliary device corresponding to the target remaining cabinet temperature is determined;

[0043] A working remaining auxiliary device is determined according to the target remaining auxiliary device, and the working remaining auxiliary device is located between the target remaining auxiliary device and the air outlet assembly;

[0044] The working remaining auxiliary device is started, and a working direction of the working remaining auxiliary device is controlled to be a vertical downward direction;

[0045] The second air outlet subassembly is started, and the second air outlet subassembly ventilates an inside of the low-voltage cabinet.

[0046] By adopting the technical scheme, after the target remaining auxiliary device appears in the remaining auxiliary device, the working remaining auxiliary device is started, the working direction of the working remaining auxiliary device is a vertical downward direction, the second air outlet subassembly is started, and air with a reduced temperature is sent to the target remaining auxiliary device, so that the temperature is reduced, and the cooling efficiency of the low-voltage cabinet is ensured.

[0047] Optionally, a high-temperature area corresponding to the target remaining auxiliary device is determined according to the target remaining cabinet temperature.

[0048] According to the relative position relationship between the high-temperature area and the target remaining auxiliary device, a target remaining direction is generated.

[0049] If the included angle between the target remaining direction and a preset horizontal direction is positive, the target remaining auxiliary device is controlled to work according to the target remaining direction.

[0050] If the included angle between the target remaining direction and the preset horizontal direction is negative, the target remaining auxiliary device is controlled to work according to the preset horizontal direction.

[0051] By adopting the technical scheme, the included angle between the target remaining direction of the target remaining auxiliary device and the preset horizontal direction is adjusted, and the working direction of the target remaining auxiliary device is selected, so that the temperature can be reduced as much as possible under the premise of ensuring the gas flow in the low-voltage cabinet, and the cooling efficiency of the low-voltage cabinet is improved.

[0056] A processor, and the program in the memory can be loaded and executed by the processor and implement the cooling method for the low-voltage cabinet.

[0057] By adopting the technical scheme, whether the overheat phenomenon occurs in the low-voltage cabinet is determined by combining the cabinet temperature and the temperature rise value, and the abnormal position is determined after the overheat phenomenon occurs. If the abnormal position is in the middle part of the low-voltage cabinet, the target auxiliary device and the conduction channel are used to achieve cooling. Since the conduction channel penetrates the containing cavity, the temperature of the air flowing in the conduction channel is relatively low, and when the target auxiliary device is used, the air is attracted from the conduction channel, so that the temperature of the air used for cooling is relatively low, and the cooling efficiency of the low-voltage cabinet is improved.

[0077] To make the purpose, technical solution, and advantages of this application clearer, the following description is provided in conjunction with the appendix. Figure 1 To be continued Figure 11 The present application will be further described in detail below with reference to embodiments. It should be understood that the specific embodiments described herein are for illustrative purposes only and are not intended to limit the scope of the application.

[0078] This application discloses a method for cooling a low-voltage switchgear. (Refer to...) Figure 1 The method includes:

[0079] Step S101: Monitor the internal and external temperatures of the low-voltage switchgear.

[0080] The internal temperature refers to the temperature inside the low-voltage switchgear. There can be multiple internal temperatures. For example, each cavity of the low-voltage switchgear is equipped with a temperature sensor, which obtains the specific temperature value inside the switchgear.

[0081] The cabinet-out temperature refers to the ambient temperature outside the low-voltage cabinet. For example, the low-voltage cabinet is arranged in a room, and the temperature inside the room is the cabinet-out temperature.

[0082] Step S102: Calculate the difference between the cabinet-in temperature and the cabinet-out temperature to obtain a temperature rise value.

[0083] The temperature rise value can directly reflect the cabinet-in capacity of the low-voltage cabinet. The higher the temperature rise value, the worse the heat dissipation capacity of the heat dissipation cabinet, and the more the low-voltage cabinet needs to be promoted to dissipate heat.

[0084] Step S103: If the cabinet-in temperature is greater than a first temperature threshold or the temperature rise value is greater than a second temperature threshold, an abnormal position corresponding to the cabinet-in temperature is obtained.

[0085] The first temperature threshold is a preset empirical value, and the first temperature threshold is related to the upper limit of the heat resistance of the internal elements of the low-voltage cabinet. For example, the first temperature threshold is 60°C.

[0086] The second temperature threshold is a preset empirical value, for example, the second temperature threshold is 40°C.

[0087] For example, a temperature sensor corresponding to the cabinet-in temperature is determined, and a position where the temperature sensor is located is set as the abnormal position.

[0088] Step S104: If the abnormal position is located at the bottom or the top of the low-voltage cabinet, a cooling device of the low-voltage cabinet is started. The cooling device includes an air inlet assembly located at the bottom of the low-voltage cabinet and an air outlet assembly located at the top of the low-voltage cabinet. A plurality of accommodating cavities are arranged in the low-voltage cabinet, and an auxiliary device is arranged in the accommodating cavity. The auxiliary device is close to a conduction channel in the low-voltage cabinet, and the conduction channel penetrates the accommodating cavity.

[0089] Optionally, the cooling device adopts a fan.

[0090] For example, please refer to Figure 2 The low-voltage cabinet 20 includes a cooling device, and the cooling device includes an air inlet assembly 21 located at the bottom of the low-voltage cabinet and an air outlet assembly 22 located at the top of the low-voltage cabinet. A plurality of accommodating cavities 25 are arranged in the low-voltage cabinet 20, and an auxiliary device 23 is arranged in the accommodating cavity. The auxiliary device 23 is close to a conduction channel 24 in the low-voltage cabinet 20, and the conduction channel 24 penetrates the accommodating cavity 25. The accommodating cavity 25 is used to place the elements of the low-voltage cabinet 20. Further, the accommodating cavity 25 is formed by the arrangement of a partition plate 26, and the partition plate 26 can be a metal mesh plate, and air can pass through the partition plate 26.

[0091] Optionally, the temperature sensor is arranged inside the accommodating cavity, so that the abnormal position corresponding to the accommodating cavity can be determined through the position of the temperature sensor, and whether the abnormal position is located at the bottom or the top of the low-voltage cabinet is determined through the accommodating cavity corresponding to the abnormal position. For example, please refer to Figure 2If the accommodating cavity 251 is at the bottom of the low-voltage cabinet 20, it is considered that the accommodating cavity 251 is at the bottom of the low-voltage cabinet 20, and it is further considered that the abnormal position is at the bottom of the low-voltage cabinet 20. If the accommodating cavity 252 is at the top of the low-voltage cabinet 20, it is considered that the accommodating cavity 252 is at the top of the low-voltage cabinet 20, and it is further considered that the abnormal position is at the top of the low-voltage cabinet 20.

[0092] If the abnormal position is at the bottom or the top of the low-voltage cabinet, since the cooling device includes the air inlet assembly at the bottom of the low-voltage cabinet and the air outlet assembly at the top of the low-voltage cabinet, after the cooling device is started, the air inlet assembly directly acts on the abnormal position at the bottom of the low-voltage cabinet, and the air outlet assembly directly acts on the abnormal position at the top of the low-voltage cabinet, so that the air at the abnormal position flows, thereby achieving cooling of the abnormal position.

[0093] Step S105: If the abnormal position is in the middle of the low-voltage cabinet, the cavity number of the abnormal position in the low-voltage cabinet is determined.

[0094] The cavity number is used to uniquely represent the accommodating cavity inside the low-voltage cabinet. The cavity number can be numbered in the order from top to bottom or in the order from bottom to top.

[0095] Optionally, if the abnormal position is not at the bottom or the top of the low-voltage cabinet, it is considered that the abnormal position is in the middle of the low-voltage cabinet.

[0096] Step S106: Determine the target auxiliary device corresponding to the cavity number.

[0097] For example, please refer to Figure 2 The auxiliary device 231 in the accommodating cavity 25 is regarded as the target auxiliary device if the abnormal position is in the accommodating cavity 25.

[0098] Step S107: Start the cooling device and simultaneously start the target auxiliary device, so that the target auxiliary device sucks air from the conduction channel.

[0099] For example, please refer to Figure 2 The auxiliary device 231 is the target auxiliary device, and when the auxiliary device 231 works, one end of the auxiliary device 231 sucks air from the conduction channel 24, and the other end blows air. The air in the conduction channel 24 is sent into the low-voltage cabinet 20 from the outside by the air inlet assembly 21, and the air in the conduction channel 24 is less affected by the elements inside the accommodating cavity during the flow process, so that the temperature is lower, and the cooling effect is better.

[0100] By adopting the technical scheme, whether overheating phenomenon occurs in the low-voltage cabinet is determined by combining the cabinet temperature and the temperature rise value, and the abnormal position is determined after the overheating phenomenon occurs. If the abnormal position is in the middle of the low-voltage cabinet, the target auxiliary device and the conduction channel are used to realize cooling. Since the conduction channel penetrates the containing cavity, the temperature of the air flowing in the conduction channel is low, and when the target auxiliary device is used, it will attract air from the conduction channel, ensuring that the temperature of the air used for cooling is low, thereby improving the cooling efficiency of the low-voltage cabinet.

[0101] In the following embodiments, if two abnormal positions occur, two auxiliary devices need to be turned on at the same time, and the operation of the auxiliary devices will affect each other. To reduce the influence, the present application discloses a method for operating an auxiliary device. Figure 3 The method comprises:

[0102] Step S301: In the case where two abnormal positions exist, a first abnormal position and a second abnormal position are determined.

[0103] In some embodiments, the first abnormal position and the second abnormal position both refer to the position of the temperature sensor in the containing cavity.

[0104] In some embodiments, the temperature sensor can adopt an infrared sensor, at this time, the cabinet temperature at each place in the containing cavity where the infrared sensor is located can be obtained, at this time, the specific position of a certain place can be regarded as an abnormal position.

[0105] Step S302: A first auxiliary position corresponding to the first abnormal position and a second auxiliary position corresponding to the second abnormal position are determined.

[0106] For example, as shown in Figure 4 , the auxiliary device 231 is located below the auxiliary device 232, the auxiliary device 231 is the first auxiliary device, and the auxiliary device 232 is the second auxiliary device.

[0107] Further, when the first auxiliary device works, the first auxiliary device will extract part of the air from the conduction channel, so that the temperature of the air sucked from the conduction channel by the second auxiliary device is high, which affects the cooling of the second abnormal position by the second auxiliary device.

[0108] Step S303: A first angle is obtained according to the relative positional relationship between the position of the first auxiliary device and the first abnormal position.

[0109] Taking the position of the first auxiliary device as the origin, a first ray is obtained by emitting to the first abnormal position. The included angle between the first ray and the ray vertically upward is taken to obtain the first angle.

[0110] For example, as shown in Figure 4The first ray is emitted from the position of the first auxiliary device 231 to the first abnormal position 41.

[0111] The second angle is obtained according to the relative position relationship between the position of the first auxiliary device and the second abnormal position.

[0112] The second ray is emitted from the position of the first auxiliary device to the second abnormal position. The second angle is obtained by taking the included angle between the second ray and the ray in the vertical upward direction.

[0113] For example, refer to Figure 4 The second ray is emitted from the position of the first auxiliary device 231 to the second abnormal position 42.

[0114] Step S305: Control the working direction of the first auxiliary device to swing between the first angle and the second angle.

[0115] The working direction refers to the blowing direction of the auxiliary device.

[0116] Controlling the working direction of the first auxiliary device to swing between the first angle and the second angle can not only cool the first abnormal position and the second abnormal position, but also compensate for the influence of the deviation of the cooling effect of the second auxiliary device.

[0117] Step S306: Control the working direction of the second auxiliary device to align with the second abnormal position.

[0118] Controlling the working direction of the second auxiliary device to align with the second abnormal position can cool the abnormally high temperature at the second abnormal position, so as to ensure the normal operation of the low-voltage cabinet as much as possible.

[0119] By adopting the above technical solutions, in the case that there are two abnormal positions, the first auxiliary device and the second auxiliary device are determined, the working direction of the first auxiliary device swings between the first angle and the second angle, and the working direction of the second auxiliary device is controlled to align with the second abnormal position. The operation mode of the first auxiliary device can not only cool the two abnormal positions, but also promote the air flow in the containing cavity, thereby improving the cooling efficiency of the low-voltage cabinet.

[0120] In the following embodiments, in the process that the first auxiliary device and the second auxiliary device are both working, the temperature of the first abnormal position or the second abnormal position may still be too high, which affects the normal work of the low-voltage cabinet. Therefore, the present application embodiment discloses a second running method of an auxiliary device. Refer to Figure 5 The method comprises:

[0121] Step S501: monitoring the first cabinet temperature at the first abnormal position and the second cabinet temperature at the second abnormal position.

[0122] The first cabinet temperature refers to the temperature at the first abnormal position or the temperature in the accommodating cavity corresponding to the first abnormal position.

[0123] The second cabinet temperature refers to the temperature at the second abnormal position or the temperature in the accommodating cavity corresponding to the second abnormal position.

[0124] Step S502: in response to detecting that the first cabinet temperature is greater than the first temperature threshold, controlling the working direction of the first auxiliary device to be aligned with the first abnormal position.

[0125] When the first cabinet temperature is detected to be greater than the first temperature threshold, it indicates that the temperature at the first abnormal position is too high, and the first abnormal position has a risk of overheating. Therefore, the working direction of the first auxiliary device is controlled to be aligned with the first abnormal position, so that the first auxiliary device continuously cools the first abnormal position to reduce the temperature at the first abnormal position as much as possible.

[0126] Step S503: in response to detecting that the second cabinet temperature is greater than the first temperature threshold, controlling the working direction of the first auxiliary device to be aligned with the second abnormal position.

[0127] When the second cabinet temperature is detected to be greater than the first temperature threshold, it indicates that the temperature at the second abnormal position is too high, and the second abnormal position has a risk of overheating. Therefore, the working direction of the first auxiliary device is controlled to be aligned with the second abnormal position, so that the first auxiliary device continuously cools the second abnormal position to reduce the temperature at the first abnormal position as much as possible.

[0128] Step S504: if the second cabinet temperature is greater than the first temperature threshold within a preset time period, reducing the working power of the first auxiliary device and increasing the working power of the second auxiliary device.

[0129] The preset time period is a preset empirical value, for example, the preset time period is 2 minutes.

[0130] When the second cabinet temperature is detected to be greater than the first temperature threshold within the preset time period, it indicates that the temperature of the second abnormal position is continuously abnormal, and the cooling means in step S502 has less effect on the second abnormal position. Therefore, in this step, the working power of the first auxiliary device needs to be reduced and the working power of the second auxiliary device needs to be increased. In the case of reducing the influence of the first auxiliary device on the conduction channel, the air temperature sent into the accommodating cavity by the second auxiliary device is low, and the working power of the second auxiliary device is increased to ensure the cooling effect of the second auxiliary device.

[0131] By adopting the technical scheme, when the first in-cabinet temperature at the first abnormal position is detected to be greater than the first temperature threshold, the working direction of the first auxiliary device is controlled to be aligned with the first abnormal position, so as to ensure the cooling effect of the first abnormal position. When the second in-cabinet temperature at the second abnormal position is detected to be greater than the first temperature threshold, the working direction of the first auxiliary device is controlled to be aligned with the second abnormal position, and the first auxiliary device is turned off and the working power of the second auxiliary device is increased when the second in-cabinet temperature is greater than the first temperature threshold within a preset time length, so as to reduce the influence of the first auxiliary device on the air in the conduction channel, ensure the cooling effect of the second auxiliary device, and further improve the cooling efficiency of the low-voltage cabinet.

[0132] In the following embodiments, during the working process of the auxiliary device, the change of the in-cabinet temperature needs to be paid attention to in real time, and corresponding measures need to be taken when the in-cabinet temperature further increases, so as to ensure the cooling efficiency of the low-voltage cabinet. Therefore, the present application discloses a joint control method of an auxiliary device. Referring to Figure 6 The method comprises:

[0133] Step S601: In response to detecting that the in-cabinet temperature is greater than a third temperature threshold, determining a lower auxiliary device of a target auxiliary device, and the third temperature threshold is greater than the first temperature threshold.

[0134] The third temperature threshold is a preset empirical value, for example, the third temperature threshold is 70℃.

[0135] The lower auxiliary device is located in a containing cavity one layer below the target auxiliary device. For example, the target auxiliary device is located in the third layer containing cavity from top to bottom in the low-voltage cabinet, and the lower auxiliary device is the auxiliary device in the fourth layer containing cavity.

[0136] Step S602: Setting a target direction of the lower auxiliary device according to the positional relationship between the abnormal position and the lower auxiliary device.

[0137] For example, a direction connecting line is obtained by connecting the positions of the abnormal position and the lower auxiliary device. The target direction is obtained by taking the direction from the position of the lower auxiliary device to the abnormal position on the direction connecting line.

[0138] Step S603: Setting the working power of the lower auxiliary device according to the difference between the in-cabinet temperature and the first temperature threshold.

[0139] In some embodiments, the difference between the in-cabinet temperature and the first temperature threshold is calculated to obtain a temperature deviation value. In a preset temperature-power mapping table, the working power corresponding to the temperature deviation value is determined. The temperature-power mapping table is used to record the mapping relationship between the temperature and the working power. The temperature-power mapping table can be obtained by repeated experiments of technicians.

[0140] Step S604: Turn on the lower auxiliary device according to the working power, and control the lower auxiliary device to work towards the target direction.

[0141] For example, after turning on the lower auxiliary device, the power of the lower auxiliary device is adjusted to the working power, and the working direction of the lower auxiliary device is adjusted to the target direction.

[0142] By adopting the above technical solution, when it is detected that the temperature in the cabinet is greater than the third temperature threshold, the lower auxiliary device is turned on, and the lower auxiliary device is used to cool the abnormal position, so as to quickly reduce the temperature at the abnormal position, and realize the rapid cooling of the low-voltage cabinet.

[0143] In the following embodiments, if the temperature of the air in the conduction channel is too high, the cooling effect of the target auxiliary device will be affected, so the temperature of the air in the conduction channel needs to be monitored to ensure that the auxiliary device can attract air with lower temperature. Therefore, the present application discloses a second auxiliary device joint control method. Referring to Figure 7 , the method comprises:

[0144] Step S701: Monitor the temperature in the conduction channel to obtain the conduction temperature.

[0145] Optionally, a temperature sensor is also arranged in the conduction channel, and the conduction temperature is obtained through the reading of the temperature sensor.

[0146] Further, a plurality of temperature sensors are arranged in the conduction channel, and the reading of the temperature sensor closest to the target auxiliary device is taken as the conduction temperature.

[0147] Step S702: In the case that the conduction temperature is greater than a fourth temperature threshold, a shielding auxiliary device is determined according to the target auxiliary device, and the shielding auxiliary device is located between the target auxiliary device and the air inlet assembly.

[0148] The fourth temperature threshold is a preset empirical value, and the technical personnel can adjust the specific value of the fourth temperature threshold according to the actual demand.

[0149] Optionally, if the cavity numbers are arranged from bottom to top, after the cavity number corresponding to the target auxiliary device is determined as n, the cavity number is reduced by one to obtain n-1. The auxiliary devices corresponding to the cavity numbers 1 to n-1 are taken as the shielding auxiliary devices.

[0150] For example, referring to Figure 8 , the target auxiliary device is the auxiliary device 231, and the shielding auxiliary device is the auxiliary device 233.

[0151] Step S703: Turn on the shielding auxiliary device, and control the working direction of the shielding auxiliary device to be a vertical upward direction.

[0152] The power of the shielding auxiliary device is adjusted according to the power of the air supply assembly, so that the air speed corresponding to the shielding auxiliary device is consistent with the air speed corresponding to the air supply assembly.

[0153] When the working directions of the shielding auxiliary devices are all vertical upward directions, the air blown by the shielding auxiliary devices can form an air wall, and the air speed corresponding to the shielding auxiliary devices is consistent with the air speed corresponding to the air supply assembly, so that the air in the accommodation cavity and the conduction channel is separated, the air flows quickly along the conduction channel, the amount of air entering the accommodation cavity from the conduction channel is reduced, and the amount of air in the accommodation cavity entering the conduction channel is also reduced.

[0154] For example, as shown in FIG. 2, the working directions of the auxiliary devices 232 and 233 are all vertical upward directions. Figure 8

[0155] Step S704: determining a blocking auxiliary device according to the target auxiliary device, the blocking auxiliary device being located in an upper accommodation cavity of an accommodation cavity where the target auxiliary device is located.

[0156] Optionally, if the cavity numbers are arranged from bottom to top, the cavity number n corresponding to the target auxiliary device is added by one to obtain n+1. The auxiliary device corresponding to the cavity number n+1 is taken as the blocking auxiliary device.

[0157] Step S705: turning on the blocking auxiliary device and controlling the working direction of the blocking auxiliary device to be directed to the conduction channel.

[0158] The working direction of the blocking auxiliary device is an acute angle with the horizontal direction, and the working direction is higher than the horizontal direction.

[0159] By turning on the blocking auxiliary device and controlling the working direction of the blocking auxiliary device to be directed to the conduction channel, the air blown by the blocking auxiliary device can be used to limit the air flow in the conduction channel, so that the air does not continue to flow above the target auxiliary device.

[0160] For example, as shown in FIG. 2, the working directions of the auxiliary devices 232 and 233 are all vertical upward directions. Figure 8

[0161] By adopting the above technical solution, if the temperature in the conduction channel is greater than the fourth temperature threshold, the shielding auxiliary device and the blocking auxiliary device are turned on, the working direction of the shielding auxiliary device is a vertical upward direction, and the working direction of the blocking auxiliary device is directed to the conduction channel, so that an isolation zone is formed between the conduction channel and the accommodation cavity, and the air with a lower temperature is directly sent to the target auxiliary device.

[0162] ​​In the following embodiments, for the auxiliary devices other than the target auxiliary device, the shielding auxiliary device and the blocking auxiliary device, these auxiliary devices are located above the target auxiliary device, and cannot be cooled by the conduction channel, so these auxiliary devices are prone to overheating, and therefore need to be separately cooled, and therefore the present application discloses a method three for jointly controlling auxiliary devices. Referring to Figure 9 The method comprises the following steps:

[0163] Step S901: determining remaining auxiliary devices according to the shielding auxiliary device, the remaining auxiliary devices being located between the shielding auxiliary device and the air outlet assembly.

[0164] The air outlet assembly comprises a first air outlet sub-assembly and a second air outlet sub-assembly, the first air outlet sub-assembly being used for ventilating the accommodation cavity, and the second air outlet sub-assembly being used for ventilating the conduction channel.

[0165] For example, referring to Figure 8 The remaining auxiliary devices are the auxiliary device 234 and the auxiliary device 235.

[0166] Step S902: obtaining remaining cabinet temperatures corresponding to the remaining auxiliary devices.

[0167] The remaining cabinet temperature refers to the temperature in the accommodation cavity corresponding to the remaining auxiliary device. Optionally, the remaining cabinet temperature can be measured by a temperature sensor in the accommodation cavity corresponding thereto.

[0168] Step S903: if there is a target remaining cabinet temperature greater than the first temperature threshold in the remaining cabinet temperatures, determining a target remaining auxiliary device corresponding to the target remaining cabinet temperature.

[0169] The target remaining cabinet temperature is any one of the remaining cabinet temperatures. The target remaining auxiliary device is one of the remaining auxiliary devices.

[0170] Step S904: determining a working remaining auxiliary device according to the target remaining auxiliary device, the working remaining auxiliary device being located between the target remaining auxiliary device and the air outlet assembly.

[0171] For example, referring to Figure 8 If the target remaining auxiliary device is the auxiliary device 234, the working remaining auxiliary device is the auxiliary device 235.

[0172] Step S905: starting the working remaining auxiliary device, so that the working direction of the working remaining auxiliary device is a vertical downward direction.

[0173] When the working remaining auxiliary device is started and the working direction of the working remaining auxiliary device is a vertical downward direction, the air in the containing cavity and the conduction channel can be separated, the air can flow quickly along the conduction channel, and the amount of air entering the containing cavity from the conduction channel and the amount of air in the containing cavity entering the conduction channel can be reduced.

[0174] Step S906: Start the second air outlet subassembly, and make the second air outlet subassembly ventilate the inside of the low-voltage cabinet.

[0175] When the second air outlet subassembly is started and the second air outlet subassembly ventilates the inside of the low-voltage cabinet, the second air outlet subassembly can provide part of ventilation for the conduction channel, and the target remaining auxiliary device can use the air provided by the second air outlet subassembly to cool the containing cavity. Moreover, since the shielding auxiliary device is in working, the conduction channel can be divided into two parts, and the interference between the two parts is small.

[0176] By using the above technical solution, after the target remaining auxiliary device appears in the remaining auxiliary device, the working remaining auxiliary device is started, the working direction of the working remaining auxiliary device is a vertical downward direction, and the second air outlet subassembly is started to send the air with reduced temperature to the target remaining auxiliary device, so that cooling is realized and the cooling efficiency of the low-voltage cabinet is ensured.

[0177] The embodiment of the application discloses a kind of combined control methods of auxiliary device four. Refer to Figure 10 , the method comprises:

[0178] Step S1001: determine the high temperature area corresponding to the target remaining auxiliary device according to the target remaining cabinet temperature.

[0179] Illustratively, compare the target remaining cabinet temperature with the first temperature threshold. Take the area where the target remaining cabinet temperature is greater than the first temperature threshold to obtain the high temperature area.

[0180] Step S1002: generate target remaining direction according to the relative position relationship between the high temperature area and the target remaining auxiliary device.

[0181] Illustratively, make the position of the target remaining auxiliary device point to the vector of the high temperature area, and the direction of the vector is taken as the target remaining direction.

[0182] Step S1003: if the included angle between the target remaining direction and the preset horizontal direction is positive, control the target remaining auxiliary device to work according to the target remaining direction.

[0183] Illustratively, in the view angle shown in Figure 8 , the preset horizontal direction is the horizontal right direction, and if the component of the target remaining direction in the vertical direction is the vertical upward direction, it is considered that the included angle between the target remaining direction and the preset horizontal direction is positive.

[0184] Step S1004: If the included angle between the target residual direction and the preset horizontal direction is negative, controlling the target residual auxiliary device to work according to the preset horizontal direction.

[0185] If the component of the target residual direction in the vertical direction is the vertical downward direction, it is considered that the included angle between the target residual direction and the preset horizontal direction is negative.

[0186] If the target residual auxiliary device is controlled to work according to the target residual direction, it will cause serious interference between the wind blown by the target residual auxiliary device and the wind sent by the air inlet assembly, and the cooling effect of the target residual auxiliary device will be greatly reduced.

[0187] By adopting the above technical solution, the included angle between the target residual direction of the target residual auxiliary device and the preset horizontal direction is adjusted to select the working direction of the target residual auxiliary device, so that the temperature can be reduced as much as possible and the cooling efficiency of the low-voltage cabinet can be improved under the premise of ensuring the gas flow in the low-voltage cabinet.

[0191] The processor 1103, the program in the memory can be loaded and executed by the processor and realize the above-mentioned cooling method of the low-voltage cabinet.

[0192] By adopting the above technical solution, the temperature in the cabinet and the temperature rise value are combined to judge whether the overheating phenomenon occurs in the low-voltage cabinet, and the abnormal position is determined after the overheating phenomenon occurs. If the abnormal position is in the middle part of the low-voltage cabinet, the target auxiliary device and the conduction channel are used to realize cooling. Since the conduction channel penetrates the containing cavity, the temperature of the air flowing in the conduction channel is low, and when the target auxiliary device is used, it will attract air from the conduction channel, so that the temperature of the air used for cooling is low, thereby improving the cooling efficiency of the low-voltage cabinet.
