Description

Technical Field

[0001] The present application relates to the field of power distribution cabinet technology, and in particular to a method and system for controlling the temperature of a power distribution cabinet. Background Art

[0002] A distribution cabinet, also often called a distribution box or distribution board, is an electrical device used for power distribution. Its main function is to receive and distribute electrical energy.

[0003] In related technologies, in order to ensure the safe and stable operation of electrical equipment in the distribution cabinet, heat dissipation equipment such as exhaust fans are usually installed on the distribution cabinet. After the temperature sensor installed on the distribution cabinet detects that the temperature inside the distribution cabinet reaches the preset safety temperature, it starts to control the exhaust fan to start to cool the distribution cabinet.

[0004] Regarding the above-mentioned related technologies, the safe temperature is a temperature that will not cause damage to the distribution cabinet, but the safe temperature is still a relatively high temperature. After the temperature inside the distribution cabinet reaches the safe temperature, it is cooled down. The distribution cabinet will be at the safe temperature for a long time. When the distribution cabinet is at a high temperature above the safe temperature for a long time, it is very easy to cause aging of the components in the distribution cabinet, resulting in poor heat dissipation protection effect on the distribution cabinet, and there is still room for improvement. Summary of the Invention

[0005] In order to improve the protective effect of heat dissipation on the power distribution cabinet, the present application provides a temperature control method and system for the power distribution cabinet.

[0006] In a first aspect, the present application provides a method for controlling the temperature of a power distribution cabinet, which adopts the following technical solution:

[0007] A method for controlling temperature of a power distribution cabinet, comprising:

[0008] Get the load power information of the preset power distribution cabinet;

[0009] Determine the heat generation information of the distribution cabinet based on the load power information and the preset heat generation power relationship information;

[0010] Obtain heat dissipation information of the power distribution cabinet;

[0011] Determine whether the heat generation information meets the requirements of the heat dissipation information;

[0012] If it meets the requirements, continue to obtain the load power information of the distribution cabinet for cyclic judgment;

[0013] If not, obtain the power maintenance time information of the power distribution cabinet;

[0014] The power maintenance time information, heat generation information and heat dissipation information are analyzed to control the preset temperature control device to adjust the temperature of the distribution cabinet.

[0015] By adopting the above technical solution, when the heat generation information of the distribution cabinet exceeds the heat dissipation information of the distribution cabinet, it indicates that when working with the current load power information, the distribution cabinet will continue to heat up, and the temperature control device is controlled to lower the temperature of the distribution cabinet according to the power maintenance time information, heat generation information and heat dissipation information, so as to cool down the distribution cabinet before the temperature rises, so as to delay or prevent the temperature of the distribution cabinet from rising to a safe temperature, thereby improving the protection effect of heat dissipation on the distribution cabinet.

[0016] Optionally, the step of analyzing the power maintenance time information, the heat generation information, and the heat dissipation information to control a preset temperature control device to adjust the temperature of the power distribution cabinet includes:

[0017] Calculate the product of the power maintenance time information and the heat generation information, and define the calculated product as the total heat generation information;

[0018] Determine temperature change value information based on total heat output information and preset heat-temperature relationship information;

[0019] Get the initial temperature information of the power distribution cabinet;

[0020] Calculate the sum of the initial temperature information and the temperature change value information, and define the calculated sum as the final temperature information;

[0021] Determine whether the final temperature information meets the requirements of the preset safety temperature information;

[0022] If it meets the requirements, continue to obtain the load power information of the distribution cabinet for cyclic judgment;

[0023] If not, the difference between the heat generation information and the heat dissipation information is calculated, and the calculated difference is defined as the heat deviation information;

[0024] The temperature control device is controlled to adjust the temperature of the power distribution cabinet based on analysis of the heat deviation information and the power maintenance time information.

[0025] By adopting the above technical solution, when it is determined that the final temperature information of the distribution cabinet can reach the safe temperature information, the temperature control device is controlled to adjust the temperature of the distribution cabinet according to the heat deviation information and the power maintenance time information, instead of adjusting it regardless of the final temperature, thereby improving the rationality of the temperature adjustment of the distribution cabinet.

[0026] Optionally, the step of analyzing the heat deviation information and the power maintenance time information to control the temperature control device to adjust the temperature of the power distribution cabinet includes:

[0027] determining temperature control heat dissipation information of the temperature control device according to the heat deviation information;

[0028] Obtain active heat dissipation information of the temperature control device;

[0029] Determine whether the temperature control heat dissipation information meets the requirements of active heat dissipation information;

[0030] If it does not meet the requirements, the temperature of the power distribution cabinet will be adjusted according to the preset power reduction method;

[0031] If it meets the requirements, the power maintenance time information is analyzed to determine the temperature control time information;

[0032] The temperature control device is controlled according to the temperature control time information and the temperature control heat dissipation information to reduce the temperature of the power distribution cabinet.

[0033] By adopting the above technical solution, when the temperature-controlled heat dissipation information exceeds the active heat dissipation information, it indicates that even if the temperature control device performs temperature adjustment, the temperature of the distribution cabinet will still rise. Therefore, the temperature of the distribution cabinet is adjusted according to the power reduction method; when the temperature-controlled heat dissipation information does not exceed the active heat dissipation information, the temperature control device is controlled to reduce the temperature of the distribution cabinet according to the temperature control time information and the temperature control heat dissipation information, thereby improving the rationality of the temperature adjustment method of the distribution cabinet.

[0034] Optionally, the step of analyzing the power maintenance time information to determine the temperature control time information includes:

[0035] Calculate the difference between the safety temperature information and the initial temperature information, and define the calculated difference as temperature concession information;

[0036] determining temperature increase information based on the heat deviation information and the heat-temperature relationship information;

[0037] Calculating a quotient between the temperature concession information and the temperature increase information, and defining the calculated quotient as time concession information;

[0038] The difference between the power maintenance time information and the time concession amount information is calculated, and the calculated difference is defined as the temperature control time information.

[0039] By adopting the above technical solution, the quotient between the temperature concession information and the temperature increase information is calculated to obtain the time concession information required for the distribution cabinet temperature to rise from the initial temperature to the safe temperature. Then, the difference between the power maintenance time information and the time concession information is calculated to obtain the temperature control time information, thereby improving the accuracy of the temperature control time.

[0040] Optionally, the step of obtaining active heat dissipation information of the temperature control device includes:

[0041] Get ambient temperature information;

[0042] Determine whether the ambient temperature information meets the requirements of the initial temperature information;

[0043] If it meets the requirements, the inlet air temperature difference information of the temperature control device is obtained;

[0044] Analyze the inlet air temperature difference information, the preset maximum air volume information and the air specific heat capacity information to determine the active heat dissipation information;

[0045] If not, obtain the outlet temperature difference information of the temperature control device;

[0046] The active heat dissipation information is determined by analyzing the outlet air temperature difference information, the preset maximum air volume information and the air specific heat capacity information.

[0047] By adopting the above technical solution, the inlet cooling or outlet cooling of the temperature control device is determined according to the size relationship between the ambient temperature information and the initial temperature information, so as to determine the active heat dissipation information of the temperature control device according to different cooling methods, thereby improving the accuracy of the active heat dissipation information.

[0048] Optionally, the step of adjusting the temperature of the power distribution cabinet according to a preset power reduction method includes:

[0049] Control the temperature control device to lower the temperature of the power distribution cabinet based on the active heat dissipation information, and obtain the actual temperature information of the power distribution cabinet in real time;

[0050] When the actual temperature information is equal to the safety temperature information, the safety power information is determined according to the active heat dissipation information, the heat dissipation information and the heating power relationship information;

[0051] The power of the power distribution cabinet is reduced according to the safety power information to adjust the temperature of the power distribution cabinet.

[0052] By adopting the above technical solution, when the temperature control device is controlled to lower the temperature of the distribution cabinet using the active heat dissipation information, when it is determined that the actual temperature information is equal to the safety temperature information, the power of the distribution cabinet is reduced using the safety power information, thereby extending the working time of the distribution cabinet as much as possible, and timely lowering the temperature of the distribution cabinet, thereby improving the rationality of the temperature control of the distribution cabinet.

[0053] Optionally, the step of reducing the power of the power distribution cabinet according to the safety power information to adjust the temperature of the power distribution cabinet includes:

[0054] Obtain detailed load power information of the distribution cabinet and the corresponding load serial number information;

[0055] Obtain the corresponding rated load power information according to the load serial number information;

[0056] Calculating a difference between the detailed load power information and the corresponding rated load power information, and defining the calculated difference as excess power information;

[0057] Analyze the excess power information and the corresponding load sequence number information to determine load reduction sequence information;

[0058] Calculating a difference between the load power information and the safety power information, and defining the calculated difference as reduced power information;

[0059] analyzing the load reduction sequence information, the detailed load power information, and the power reduction information to determine load power reduction parameter information;

[0060] The power distribution cabinet is controlled to reduce power according to the load power reduction parameter information to adjust the temperature of the power distribution cabinet.

[0061] By adopting the above technical solution, the load sequence information is sorted according to the size of the excess power information to obtain the load reduction sequence information, and then the load power reduction parameter information is determined based on the load reduction sequence information, detailed load power information and power reduction information, so as to stop the load with the highest heat generation, thereby improving the cooling effect of the distribution cabinet.

[0062] In a second aspect, the present application provides a temperature control system for a power distribution cabinet, which adopts the following technical solution:

[0063] A temperature control system for a power distribution cabinet, comprising:

[0064] An acquisition module is used to obtain load power information, heat dissipation information, and power maintenance time information;

[0065] A memory, used to store a program of a temperature control method for a power distribution cabinet as described in any one of the above items;

[0066] The processor and the program in the memory can be loaded and executed by the processor to implement a temperature control method for a power distribution cabinet as described in any one of the above items.

[0067] By adopting the above technical solution, a series of data related to the temperature control of the distribution cabinet is obtained through the acquisition module, and the processor is controlled to load and execute a program of a distribution cabinet temperature control method stored in the memory, so that when the distribution cabinet is working, it is determined that the distribution cabinet will heat up to a safe temperature, and the temperature control device is promptly controlled to cool down in advance to delay or prevent the temperature of the distribution cabinet from reaching a safe temperature, prevent the distribution cabinet from being in a high temperature state for a long time, and thereby improve the protection effect of heat dissipation on the distribution cabinet.

[0068] In summary, this application includes at least one of the following beneficial technical effects:

[0069] 1. When the heat generation information of the power distribution cabinet exceeds the heat dissipation information of the power distribution cabinet, it indicates that the power distribution cabinet will continue to heat up when operating at the current load power information. Therefore, the temperature control device is controlled to lower the temperature of the power distribution cabinet based on the power maintenance time information, heat generation information and heat dissipation information. Therefore, the temperature of the power distribution cabinet is lowered before the temperature rises, thereby delaying or preventing the temperature of the power distribution cabinet from rising to a safe temperature, thereby improving the heat dissipation protection effect on the power distribution cabinet;

[0070] 2. When the final temperature of the power distribution cabinet is determined to have reached the safe temperature, the temperature control device is controlled to adjust the temperature of the power distribution cabinet based on the heat deviation information and power maintenance time information, rather than adjusting the temperature regardless of the final temperature. This improves the rationality of the temperature adjustment of the power distribution cabinet.

[0071] 3. By calculating the quotient between the temperature concession information and the temperature increase information, the time concession information required for the distribution cabinet temperature to increase from the initial temperature to the safe temperature is obtained. Then, the difference between the power maintenance time information and the time concession information is calculated to obtain the temperature control time information, thereby improving the accuracy of the temperature control time.

[0079] In order to make the purpose, technical solutions and advantages of this application more clear, the following Figure 1-Figure 7 It should be understood that the specific embodiments described herein are only used to explain the present application and are not intended to limit the present application.

[0080] The embodiment of the present application discloses a method for controlling the cooling of a distribution cabinet, a processing terminal, a distribution cabinet and a temperature control device. The temperature control device and the processing terminal are all installed on the distribution cabinet, and the processing terminal is connected to the various components and the temperature control device on the distribution cabinet through data wires, thereby realizing data interaction and the processing terminal's control of the components and the temperature control device in the distribution cabinet. After the distribution cabinet sends the load power information to the processing terminal, the processing terminal determines the heat generation information caused by the load power information. When the heat generation information exceeds the heat dissipation information, the processing terminal calls the power maintenance time information, thereby controlling the temperature control device to cool the distribution cabinet according to the power maintenance time information, the heat generation information and the heat dissipation information. The heat generated by the distribution cabinet during operation is dissipated before the temperature of the distribution cabinet rises, delaying or preventing the distribution cabinet from being at a high temperature for a long time, thereby improving the heat dissipation protection effect on the distribution cabinet.

[0081] Reference Figure 1 , the embodiment of the present application discloses a method for controlling the temperature of a power distribution cabinet, comprising the following steps:

[0082] Step S100: Obtain load power information of a preset power distribution cabinet.

[0083] The power distribution cabinet refers to electrical equipment used to distribute power. The specific model is determined by those skilled in the art and is not described here. Load power information refers to the total load power value of the power distribution cabinet, which is obtained by sending the power to the processing terminal using a power factor meter installed on the power distribution cabinet.

[0084] Step S101: determining the heating value information of the power distribution cabinet according to the load power information and the preset heating power relationship information.

[0085] Among them, the heating power relationship information refers to a database that stores the corresponding relationship between the power of the distribution cabinet and the heat generated per unit time. The power of the distribution cabinet is directly proportional to the heat generated per unit time, that is, the greater the power of the distribution cabinet, the greater the heat generated per unit time. The ratio between the two is determined by technical personnel in this field based on the actual situation of the distribution cabinet, and the two are stored in the database after one-to-one correspondence.

[0086] The heat generation information refers to the heat generated by the distribution cabinet per unit time under the current load power. The processing terminal inputs the power value corresponding to the load power information into the database corresponding to the heat generation power relationship information, thereby matching the heat generation corresponding to the load power information and outputting it to the processing terminal.

[0087] Step S102: Obtain heat dissipation information of the power distribution cabinet.

[0088] Among them, the heat dissipation information refers to the natural heat dissipation of the distribution cabinet per unit time. The method for obtaining the heat dissipation is: first calculate the temperature difference between the inside and outside of the distribution cabinet, and then determine the positive and negative relationship of the thermal conductivity coefficient based on the positive and negative relationship of the temperature difference, and then calculate the thermal conductivity coefficient and the heat dissipation area of ​​the distribution cabinet to obtain the heat dissipation per unit time. The temperature difference can be detected by the internal and external temperature sensors, and the thermal conductivity coefficient and the heat dissipation area are stored in the processing terminal by technical personnel in this field.

[0089] Step S103: Determine whether the heat generation information meets the requirements of the heat dissipation information.

[0090] The heat dissipation requirement refers to not exceeding the heat dissipation value per unit time corresponding to the heat dissipation information. The processing terminal determines whether the heat dissipation per unit time corresponding to the heat dissipation information does not exceed the heat dissipation value per unit time corresponding to the heat dissipation information. This determines whether the heat dissipation of the power distribution cabinet in its natural state can eliminate the heat generated during operation, thereby ensuring that the temperature of the power distribution cabinet does not rise.

[0091] Step S1031: If it is true, continue to obtain the load power information of the power distribution cabinet to make a cyclic judgment.

[0092] Among them, if the processing terminal determines that the heat generation per unit time corresponding to the heat generation information does not exceed the heat dissipation value per unit time corresponding to the heat dissipation information, it indicates that the heat dissipation of the distribution cabinet in the natural state can eliminate the heat value generated during operation, and the temperature of the distribution cabinet will not rise when working. Therefore, it continues to send and receive the load power information of the distribution cabinet, thereby continuing to pay attention to changes in the working status of the distribution cabinet.

[0093] Step S1032: If not, obtain the power maintenance time information of the power distribution cabinet.

[0094] Among them, if the processing terminal determines that the heat generation per unit time corresponding to the heat generation information exceeds the heat dissipation value per unit time corresponding to the heat dissipation information, it indicates that the heat dissipation of the distribution cabinet in the natural state cannot eliminate the heat value generated during operation, and the temperature of the distribution cabinet will rise when it is working. Therefore, the power maintenance time information of the distribution cabinet is detected to provide data support for the subsequent temperature adjustment of the distribution cabinet.

[0095] The power maintenance time information refers to the time that the distribution cabinet works at the current load power. In one embodiment, a technician in this field can input it into the processing terminal to obtain it. In another embodiment, the processing terminal can call the historical power data of the distribution cabinet and analyze the time that the current time works at the current power from the historical power data.

[0096] Step S104: Analyze the power maintenance time information, the heat generation information, and the heat dissipation information to control a preset temperature control device to adjust the temperature of the power distribution cabinet.

[0097] Among them, after the processing terminal determines the power maintenance time information, it analyzes the power maintenance time information, heat information and heat dissipation information to determine the specific adjustment method to control the temperature control device to adjust the temperature of the distribution cabinet. The specific method is referred to Figure 2 steps.

[0098] The temperature control device refers to a device used to cool the distribution cabinet. Cooling fans can be installed at the bottom and top of the distribution cabinet. The cooling fans can both exhaust and blow air. The specific mode to be selected depends on which mode has a higher heat dissipation capacity.

[0099] Reference Figure 2 The steps of analyzing the power maintenance time information, the heat generation information, and the heat dissipation information to control a preset temperature control device to adjust the temperature of the power distribution cabinet include:

[0100] Step S200: Calculate the product between the power maintenance time information and the heat generation information, and define the calculated product as the total heat generation information.

[0101] The total heat generation information refers to the total heat generated by the distribution cabinet when working under the current load power, and is obtained by calculating by the processing terminal the product of the time value corresponding to the power maintenance time information and the heat generation per unit time corresponding to the heat generation information.

[0102] Step S201: determining temperature change value information according to total heat generation information and preset heat-temperature relationship information.

[0103] Among them, the heat-temperature relationship information refers to a database that stores the correspondence between the total heat output and the increased temperature of the distribution cabinet. The total heat output is proportional to the increased temperature, that is, the higher the total heat output, the higher the increased temperature. The technical personnel in this field will match the two one by one and store them in the database.

[0104] The temperature change value information refers to the temperature value that increases when the distribution cabinet is under the current total heat output. The processing terminal inputs the heat output corresponding to the total heat output information into the database corresponding to the heat-temperature relationship information, thereby matching the temperature corresponding to the total heat output and outputting it to the processing terminal.

[0105] Step S202: Acquire initial temperature information of the power distribution cabinet.

[0106] The initial temperature information refers to the temperature of the distribution cabinet when the distribution cabinet sends the load power to the processing terminal, which is detected by the temperature sensor installed in the distribution cabinet and sent to the processing terminal.

[0107] Step S203: Calculate the sum of the initial temperature information and the temperature change value information, and define the calculated sum as the final temperature information.

[0108] The final temperature information refers to the temperature value increased by the distribution cabinet without any heat dissipation, and is obtained by calculating the sum of the temperature value corresponding to the initial temperature information and the temperature value corresponding to the temperature change value information by the processing terminal.

[0109] Step S204: Determine whether the final temperature information meets the preset safety temperature information requirements.

[0110] The safety temperature information refers to the warning temperature of the power distribution cabinet. The specific value is determined by those skilled in the art based on actual conditions and stored in the processing terminal. The safety temperature information requirement is that it should not exceed the temperature value corresponding to the safety temperature information.

[0111] The processing terminal determines whether the temperature value corresponding to the final temperature information is not greater than the temperature value corresponding to the safety temperature information, thereby determining whether the increased temperature value of the distribution cabinet will cause the distribution cabinet to be at a high temperature corresponding to the safety temperature information.

[0112] Step S2041: If it is true, continue to obtain the load power information of the distribution cabinet to make a cyclic judgment.

[0113] Among them, if the processing terminal determines that the temperature value corresponding to the final temperature information is not greater than the temperature value corresponding to the safety temperature information, it means that even if working at the current load power, the temperature of the distribution cabinet will not reach the safety temperature. Therefore, it continues to send and receive the load power information of the distribution cabinet, thereby continuously monitoring the working status of the distribution cabinet.

[0114] Step S2042: If not, the difference between the heat generation information and the heat dissipation information is calculated, and the calculated difference is defined as heat deviation information.

[0115] Among them, if the processing terminal determines that the temperature value corresponding to the final temperature information is greater than the temperature value corresponding to the safety temperature information, it indicates that the distribution cabinet is working at the current load power, and the temperature of the distribution cabinet will be greater than the safety temperature. Therefore, the processing terminal calculates the difference between the heat generation corresponding to the heat generation information and the heat dissipation corresponding to the heat dissipation information to obtain the heat deviation information, which provides data support for the subsequent temperature adjustment of the distribution cabinet.

[0116] The heat deviation information refers to the excess heat generated by the power distribution cabinet per unit time, and is obtained by calculating the difference between the heat generation corresponding to the heat generation information and the heat dissipation corresponding to the heat dissipation information by the processing terminal.

[0117] Step S205: Analyze the heat deviation information and the power maintenance time information to control the temperature control device to adjust the temperature of the power distribution cabinet.

[0118] Among them, after the processing terminal receives the heat deviation information, the processing terminal determines the appropriate heat dissipation method after analyzing the heat deviation information and power maintenance time information, thereby controlling the temperature control device to adjust the temperature of the distribution cabinet. The specific method is referred to Figure 3 steps.

[0119] Reference Figure 3 The steps of analyzing the heat deviation information and the power maintenance time information to control the temperature control device to adjust the temperature of the power distribution cabinet include:

[0120] Step S300: determining the temperature control heat dissipation information of the temperature control device according to the heat deviation information.

[0121] The temperature control heat dissipation information refers to the heat dissipation actively provided by the temperature control device per unit time, that is, the heat dissipation per unit time corresponding to the heat deviation information is the same.

[0122] Step S301: Obtain active heat dissipation information of the temperature control device.

[0123] The active heat dissipation information refers to the maximum amount of heat that the temperature control device can dissipate per unit time. For specific acquisition methods, refer to Figure 5 steps.

[0124] Step S302: determining whether the temperature-controlled heat dissipation information meets the requirements of the active heat dissipation information.

[0125] The active heat dissipation requirement is that the heat dissipation per unit time must not exceed the heat dissipation per unit time corresponding to the active heat dissipation information. The processing terminal determines whether the heat dissipation per unit time corresponding to the temperature control heat dissipation information is not greater than the heat dissipation per unit time corresponding to the active heat dissipation information, thereby determining whether the power distribution cabinet will not heat up after the temperature control device actively dissipates heat.

[0126] Step S3021: If not, the temperature of the power distribution cabinet is adjusted according to a preset power reduction method.

[0127] Among them, if the processing terminal determines that the heat dissipation per unit time corresponding to the temperature control heat dissipation information is greater than the heat dissipation per unit time corresponding to the active heat dissipation information, it means that even if the temperature control device dissipates heat with the heat dissipation per unit time corresponding to the active heat dissipation information, the temperature of the distribution cabinet will still rise. Therefore, the temperature of the distribution cabinet is adjusted according to the power reduction method. The specific method is referred to Figure 6 steps.

[0128] The power reduction method refers to a method for adjusting the temperature of the power distribution cabinet by reducing the power. It is stored in the processing terminal by those skilled in the art. For specific methods, refer to Figure 6 steps.

[0129] Step S3022: If it is met, analyze the power maintenance time information to determine the temperature control time information.

[0130] Among them, if the processing terminal determines that the heat dissipation per unit time corresponding to the temperature control heat dissipation information is not greater than the heat dissipation per unit time corresponding to the active heat dissipation information, it indicates that when the temperature control device dissipates heat with the heat dissipation per unit time corresponding to the temperature control heat dissipation information, the temperature of the distribution cabinet will not rise. Therefore, the temperature control time information is determined based on the power maintenance time information to provide data support for the subsequent temperature adjustment of the distribution cabinet.

[0131] Temperature control time information refers to the heat dissipation time of the temperature control device to the distribution cabinet, which is determined by the processing terminal after analyzing the power maintenance time information. For specific methods, refer to Figure 4 steps.

[0132] Step S303: controlling the temperature control device to lower the temperature of the power distribution cabinet according to the temperature control time information and the temperature control heat dissipation information.

[0133] Among them, after the processing terminal obtains the temperature control time information, the processing terminal controls the temperature control device to cool the distribution cabinet according to the time corresponding to the temperature control time information and the air volume corresponding to the temperature control heat dissipation information.

[0134] Reference Figure 4 The steps of analyzing the power maintenance time information to determine the temperature control time information include:

[0135] Step S400: Calculate the difference between the safety temperature information and the initial temperature information, and define the calculated difference as temperature concession information.

[0136] The temperature concession information refers to the temperature value increased from the initial temperature of the distribution cabinet to the safe temperature, which is obtained by calculating the difference between the temperature value corresponding to the safe temperature information and the temperature value corresponding to the initial temperature information by the processing terminal.

[0137] Step S401: determining temperature increase information according to heat deviation information and heat-temperature relationship information.

[0138] Among them, the temperature increase information refers to the temperature value increased in the distribution cabinet per unit time. The processing terminal inputs the unit time heat value corresponding to the heat deviation information into the database corresponding to the heat-temperature relationship information, thereby matching the temperature increase information corresponding to the heat deviation information and outputting it to the processing terminal.

[0139] Step S402: Calculate the quotient between the temperature concession information and the temperature increase information, and define the calculated quotient as the time concession information.

[0140] Among them, the time concession information refers to the time required for the distribution cabinet to increase from the initial temperature to the safe temperature, which is obtained by the processing terminal calculating the quotient between the temperature value corresponding to the temperature concession information and the temperature value increased per unit time corresponding to the temperature increase information.

[0141] Step S403: Calculate the difference between the power maintenance time information and the time yield information, and define the calculated difference as the temperature control time information.

[0142] Among them, the temperature control time information in this step is consistent with the temperature control time information in step S3022. The processing terminal calculates the difference between the time value corresponding to the power maintenance time information and the time value corresponding to the time concession information, thereby making the temperature control time of the temperature control device more accurate, and ensuring that the temperature of the distribution cabinet will not exceed the safe temperature within the minimum temperature control time.

[0143] Reference Figure 5 The steps of obtaining active heat dissipation information of the temperature control device include:

[0144] Step S500: Acquire ambient temperature information.

[0145] The ambient temperature information refers to the temperature of the environment in which the power distribution cabinet is located, which is detected by a temperature sensor installed outside the power distribution cabinet and sent to the processing terminal.

[0146] Step S501: Determine whether the ambient temperature information meets the requirements of the initial temperature information.

[0147] The initial temperature information requirement is that the temperature value corresponding to the initial temperature information should not be greater than the temperature value corresponding to the initial temperature information. The processing terminal determines whether the temperature value corresponding to the ambient temperature information is greater than the temperature value corresponding to the initial temperature information, thereby determining whether the temperature control device should use exhaust cooling or intake cooling.

[0148] Step S5011: If it is met, obtain the inlet air temperature difference information of the temperature control device.

[0149] Among them, if the processing terminal determines that the temperature value corresponding to the ambient temperature information is not greater than the temperature value corresponding to the initial temperature information, it indicates that the outside temperature is low. Therefore, it is necessary to control the temperature control device to cool down the air inlet, thereby detecting the air inlet temperature difference information of the temperature control device to provide data support for the subsequent determination of the active heat dissipation information.

[0150] The inlet air temperature difference information refers to the temperature change value of the air drawn from the outside into the distribution cabinet by the temperature control device. It is obtained by calculating the difference between the readings of the internal and external temperature sensors by the processing terminal.

[0151] Step S50111: Analyze the inlet air temperature difference information, the preset maximum air volume information and the air specific heat capacity information to determine the active heat dissipation information.

[0152] The maximum air volume information in this step refers to the maximum air volume that can be supplied to the temperature control device per unit time. The specific value is input into the processing terminal by a person skilled in the art based on actual conditions. The specific heat capacity of air refers to the amount of heat required to raise a unit temperature of a unit volume of air. This constant is stored in the processing terminal by a person skilled in the art.

[0153] The active heat dissipation information in this step refers to the maximum heat dissipation when the temperature control device cools the incoming air, which is obtained by calculating by the processing terminal the product of the temperature difference corresponding to the incoming air temperature difference information, the air volume corresponding to the maximum air volume information, and the air specific heat capacity corresponding to the air specific heat capacity information.

[0154] Step S5012: If not, obtain the outlet temperature difference information of the temperature control device.

[0155] Among them, if the processing terminal determines that the temperature value corresponding to the ambient temperature information is greater than the temperature value corresponding to the initial temperature information, it indicates that the external temperature is high. Therefore, it is necessary to control the temperature control device to exhaust and cool down, so as to detect the outlet temperature difference information of the temperature control device, and provide data support for the subsequent determination of the active heat dissipation information.

[0156] The outlet air temperature difference information refers to the temperature change of the air when the temperature control device draws air from the distribution cabinet to the outside world. It is obtained by calculating the difference between the readings of the internal and external temperature sensors by the processing terminal.

[0157] Step S50121: Analyze the outlet air temperature difference information, the preset maximum air volume information, and the air specific heat capacity information to determine the active heat dissipation information.

[0158] The maximum air volume information in this step refers to the maximum air volume extracted by the temperature control device per unit time. The specific value is input into the processing terminal by a person skilled in the art based on actual conditions. The specific heat capacity of air refers to the amount of heat required to raise a unit temperature of a unit volume of air. This constant is stored in the processing terminal by a person skilled in the art.

[0159] The active heat dissipation information in this step refers to the maximum heat dissipation when the temperature control device discharges air for cooling, which is obtained by calculating by the processing terminal the product of the temperature difference corresponding to the air temperature difference information, the air volume corresponding to the maximum air volume information, and the air specific heat capacity corresponding to the air specific heat capacity information.

[0160] Reference Figure 6 The steps of adjusting the temperature of the power distribution cabinet according to the preset power reduction method include:

[0161] Step S600: controlling the temperature control device to lower the temperature of the power distribution cabinet according to the active heat dissipation information, and obtaining the actual temperature information of the power distribution cabinet in real time.

[0162] Among them, the processing terminal controls the temperature control device to lower the temperature of the distribution cabinet according to the air volume and cooling method corresponding to the active heat dissipation information, thereby delaying the time for the temperature of the distribution cabinet to reach a safe temperature as much as possible, and detecting the actual temperature information of the distribution cabinet in real time, providing data support for the subsequent determination of when to reduce the power of the distribution cabinet.

[0163] The actual temperature information refers to the operating temperature of the power distribution cabinet, which is detected by the temperature sensor installed in the power distribution cabinet and sent to the processing terminal.

[0164] Step S601: when the actual temperature information is equal to the safety temperature information, determining the safety power information according to the active heat dissipation information, the heat dissipation information, and the heating power relationship information.

[0165] Among them, after the processing terminal receives the actual temperature information, it compares the actual temperature information with the safety temperature information. After determining that the two are equal, the processing terminal determines the safety power information based on the active heat dissipation information, heat dissipation information and heating power relationship information, providing data support for the subsequent control of the distribution cabinet to achieve the purpose of reducing temperature by reducing power.

[0166] Safety power information refers to the power that will not heat up when the distribution cabinet is working under the cooling conditions of the distribution cabinet and the temperature control device. The processing terminal calculates the sum of the heat corresponding to the active heat dissipation information and the heat corresponding to the heat dissipation information to obtain the total heat dissipation. The same total heating value is obtained based on the total heat dissipation, and the total heating value is input into the database corresponding to the heating power relationship information, and the safety power when the total heating value is output by the distribution cabinet is matched.

[0167] Step S602: reducing the power of the power distribution cabinet according to the safety power information to adjust the temperature of the power distribution cabinet.

[0168] Among them, after the processing terminal obtains the safety power information, the processing terminal reduces the power of the distribution cabinet according to the power corresponding to the safety power information, thereby reducing the heat of the distribution cabinet to achieve the purpose of cooling the distribution cabinet. The specific control method refers to Figure 7 steps.

[0169] Reference Figure 7 The steps of reducing the power of the power distribution cabinet according to the safety power information to adjust the temperature of the power distribution cabinet include:

[0170] Step S700: Obtain detailed load power information of the power distribution cabinet and corresponding load serial number information.

[0171] The detailed load power information refers to the power of each load in the distribution cabinet, and the load serial number information refers to the serial number of the detailed load power information, which is obtained by the power factor meter on each load line sending the reading and its own serial number to the processing terminal.

[0172] Step S701: Obtain corresponding rated load power information according to the load serial number information.

[0173] The rated load power information refers to the rated power of each load line, which is obtained by the processing terminal calling the corresponding rated power stored in the processing terminal according to the serial number corresponding to the load serial number information.

[0174] Step S702: Calculate the difference between the detailed load power information and the corresponding rated load power information, and define the calculated difference as excess power information.

[0175] The excess power information refers to the value by which the power of each load exceeds the corresponding rated power, and is obtained by calculating the difference between the power corresponding to the detailed load power information and the power corresponding to the corresponding rated load power information by the processing terminal.

[0176] Step S703: Analyze the excess power information and the corresponding load sequence information to determine load reduction sequence information.

[0177] The load reduction sequence information refers to the order of reducing the load power. The processing terminal compares the power corresponding to the excess power information, and arranges the corresponding load sequence information in descending order to obtain the load reduction sequence information.

[0178] Step S704: Calculate the difference between the load power information and the safety power information, and define the calculated difference as reduced power information.

[0179] The power reduction information refers to the power value that the distribution cabinet needs to reduce, which is obtained by calculating the difference between the power value corresponding to the load power information and the power value corresponding to the safety power information by the processing terminal.

[0180] Step S705: Analyze the load reduction sequence information, the detailed load power information, and the power reduction information to determine load power reduction parameter information.

[0181] Among them, the load power reduction parameter information refers to the specific parameters for reducing the load power, including the load serial number and power value of the reduced power. The processing terminal sorts the power corresponding to the detailed load power information one by one according to the serial number corresponding to the load reduction sequence information, and then reduces the power corresponding to the first serial number according to the power reduction information until the reduced power is equal to the power corresponding to the power reduction information. After that, the load power reduction parameter information is obtained by counting the load serial number of the reduced power and the corresponding reduced power.

[0182] Step S706: Control the power distribution cabinet to reduce power according to the load power reduction parameter information to adjust the temperature of the power distribution cabinet.

[0183] Among them, after the processing terminal obtains the load power reduction parameter information, the processing terminal controls the distribution cabinet to reduce power according to the load number corresponding to the load power reduction parameter information and the corresponding reduced power, thereby reducing the heat generation of the distribution cabinet and further achieving the purpose of lowering the temperature.
