Description

Technical Field

[0001] The present invention relates to the field of heat dissipation control technology, and in particular to a heat dissipation control method, system, computer equipment and storage medium for a high-protection power distribution cabin. Background Art

[0002] The distribution cabin, as a core component of the power system, plays the role of effectively distributing electric energy to various types of electrical equipment. It is an indispensable part of ensuring the safe and stable supply of electricity.

[0003] In the past, power distribution cabins were mainly used in air-conditioned power distribution rooms, which usually have lower protection requirements and good natural heat dissipation conditions. However, with the advancement of technology and the expansion of application scenarios, power distribution cabins are increasingly being deployed in harsh outdoor environments, which require higher levels of protection and often require the power distribution cabin to be placed in a confined space. This change has brought new challenges, especially the significant reduction in heat dissipation space, which has put forward more stringent requirements on the environmental adaptability of high-power power distribution cabins. Therefore, how to achieve effective heat dissipation design in a high-protection level power distribution cabin has become a major difficulty in the current power distribution cabin design.

[0004] The common solution to the heat dissipation problem of such high-protection-level distribution cabins is to install heat dissipation devices such as cooling fans and ventilation shutters, and control the start and stop of temperature control equipment through temperature sensors in the cabin. These sensors are usually placed at specific locations in the air duct inside the cabin. However, this method faces multiple challenges in practical applications:

[0005] First, due to insufficient circulation turbulence in the cabin, the temperature control equipment may not respond in time, causing local overheating of certain core components in the distribution cabin, thereby accelerating the aging of insulation materials and increasing the risk of safety accidents such as short circuits or fires.

[0006] Secondly, for multi-branch distribution room equipment, since the operating status of each branch is different, when a single branch or several branches are operating independently, if the operating branch is not within the monitoring range of the temperature sensor, traditional temperature control strategies will find it difficult to accurately judge such operating conditions, which may cause the fan to fail to start in time, and then cause local overheating problems.

[0007] Finally, if the fan start-up condition is simply set to whether the distribution compartment is running, the fan may continue to run, which will not only cause unnecessary energy consumption but also reduce the operating efficiency of the entire system.

[0008] In summary, the heat dissipation design of a high protection level distribution cabin is a complex and arduous task, which requires comprehensive consideration of multiple factors to find the optimal solution.

[0059] Embodiment 1

[0060] Please refer to Figure 1 , is a flow chart of a method for controlling heat dissipation in a high-protection power distribution compartment provided in the first embodiment of the present invention. The method is implemented by a computer program of a controller deployed in the power distribution compartment. Each computer program can be visualized by a virtual functional module. In addition, the hardware involved includes a temperature sensor, a heat dissipation device, and a current sensor. The method specifically includes the following steps:

[0061] S1. Check whether the power distribution compartment is in operation; if so, execute S2; if not, continue to execute S1.

[0062] It should be noted that this step is to confirm whether the power distribution compartment is operating. If the power distribution compartment is not operating, then thermal control is not necessary.

[0063] S2. Obtain at least one ambient temperature in the power distribution compartment, at least one copper busbar temperature, and a total current flowing through the copper busbars.

[0064] It should be noted that the ambient temperature in the power distribution compartment is measured using a temperature sensor, which may include the temperatures of multiple points to obtain more comprehensive ambient temperature data.

[0065] The temperature sensor is also used to measure the temperature of the copper busbar, which is one of the components with the highest heat generation in the distribution compartment. The temperature of multiple points may also be included to obtain more comprehensive copper busbar temperature data.

[0066] Use a current sensor to measure the total current flowing through the copper busbar, as the current is directly related to the heat generated.

[0067] S3, determine whether at least one of the ambient temperatures reaches a preset first heat dissipation start temperature, or at least one of the copper busbar temperature reaches a preset second heat dissipation start temperature, or the total current of the copper busbar reaches a preset heat dissipation start current; if so, execute S4; if not, return to execute S2.

[0068] It should be noted that, when comparing the ambient temperature with the set first heat dissipation start temperature, if any of the ambient temperatures reaches or exceeds the threshold, the condition is met.

[0069] Compare the copper bar temperature with the set second heat dissipation start temperature. If any copper bar temperature reaches or exceeds this threshold, the condition is met.

[0070] Compare the total busbar current with the set heat dissipation startup current. If the total current reaches or exceeds this threshold, the condition is also met.

[0071] If any of the above conditions is met, S4 is executed; if not, the process returns to S2 to continue monitoring data.

[0072] S4, starting the heat dissipation device in the power distribution compartment to start heat dissipation.

[0073] It should be noted that when the risk of overheating is detected in the distribution compartment, the heat dissipation device is activated in time to reduce the temperature.

[0074] This heat dissipation control method can comprehensively evaluate the thermal risk in the distribution compartment and accurately control the startup of the heat dissipation device by real-time monitoring of the ambient temperature, copper busbar temperature, and total current of the copper busbar in the distribution compartment. This method not only improves the timeliness and accuracy of heat dissipation, but also helps save power consumption because the heat dissipation device is only started when necessary. This method is applicable to distribution compartments of various sizes and has wide promotion and application value.

[0075] In a detailed and specific implementation of this embodiment, additional initialization and fault detection steps are added to the original heat dissipation control process to ensure the safe and stable operation of the power distribution compartment. Specifically, before S1, the method further includes:

[0076] S0.0: After the system is turned on, the heat dissipation device in the power distribution compartment is tested to see if it is operating normally; if so, S1 is executed; if not, S0.1 is executed.

[0077] It should be noted that the purpose of this step is to detect whether the heat dissipation device can operate normally as expected, including key indicators such as its startup, operating efficiency, and response speed. If the heat dissipation device performs normally during the trial operation, without abnormal alarms or performance degradation, the system will continue to execute the subsequent S1 step and enter normal operating status monitoring; conversely, if the heat dissipation device fails or performs abnormally during the trial operation, the system will immediately enter the S0.1 step for fault handling.

[0078] S0.1. Obtain at least one ambient temperature in the power distribution compartment, at least one copper busbar temperature, and the total current flowing through the copper busbars.

[0079] It should be noted that these data are crucial for determining the current heat load status of the distribution compartment and the potential risk of overheating.

[0080] S0.2. Determine whether at least one of the ambient temperatures reaches a preset first heat dissipation start temperature, or at least one of the copper busbar temperature reaches a preset second heat dissipation start temperature, or the total current of the copper busbar reaches a preset heat dissipation start current; if so, execute S0.3; if not, return to execute S0.1.

[0081] It should be noted that these judgment conditions together constitute the early warning mechanism for the overheating risk of the distribution compartment. If any of the above conditions is met, the system will immediately enter step S0.3 and take emergency shutdown protection measures; if not, the system will return to step S0.1 and continue to monitor environmental data until an abnormality is detected or it enters a normal operating state.

[0082] S0.3, shutdown protection and high temperature alarm.

[0083] It should be noted that once the system determines that there is a risk of overheating in the power distribution compartment, it will immediately perform a shutdown protection operation to cut off the power supply that may cause further thermal damage. At the same time, the system will trigger a high temperature alarm mechanism to promptly remind the operation and maintenance personnel to pay attention to and deal with the current overheating problem through sound and light alarms, remote notifications, etc. This step is the last line of defense to ensure the safe operation of the power distribution compartment and is also a key measure to prevent potential safety accidents.

[0084] In summary, this embodiment not only improves the reliability and accuracy of the heat dissipation control of the power distribution compartment by adding a series of pre-steps from S0.0 to S0.3, but also provides a strong guarantee for the safe and stable operation of the system.

[0085] In a more detailed and careful implementation of this embodiment, after S0.3, the process of heat dissipation device fault recovery detection and heat dissipation control restart is further integrated to ensure that the power distribution compartment can safely and orderly resume operation after encountering overheating risks and being effectively handled. Specifically, after S0.3, the method further includes:

[0086] S0.4, detecting whether the fault of the heat dissipation device is restored; if so, executing S0.5; if not, continuing to execute S0.4.

[0087] It should be noted that the core of this step is to verify whether the heat sink has recovered from its previous fault state and regained the ability to operate normally through a preset detection program. If the heat sink fault has been restored, that is, it is confirmed that it has returned to normal, the system will enter step S0.5; if the fault has not been restored, the system will continue to execute step S0.4 until the heat sink status returns to normal or other fault handling measures are taken.

[0088] S0.5. Obtain at least one ambient temperature in the power distribution compartment, at least one copper busbar temperature, and the total current flowing through the copper busbars.

[0089] It should be noted that these data are crucial for evaluating the current heat load status of the distribution compartment and determining whether the cooling device needs to be restarted.

[0090] S0.6. Determine whether at least one of the ambient temperatures reaches a preset first heat dissipation start temperature, or at least one of the copper busbar temperature reaches a preset second heat dissipation start temperature, or the total current of the copper busbar reaches a preset heat dissipation start current; if so, execute S0.7; if not, return to execute S0.5.

[0091] It should be noted that these conditions together constitute the early warning mechanism for the overheating risk of the distribution compartment. If any of the above conditions is met, that is, it is judged that the distribution compartment has an overheating risk, the system will enter step S0.7; if not, the system will return to step S0.5 and continue to monitor environmental data until the overheating risk is detected or the environmental status is stable.

[0092] S0.7. Start the heat dissipation device in the power distribution compartment to start heat dissipation, and restore the high temperature alarm and machine protection.

[0093] It should be noted that once the system determines that there is a risk of overheating in the power distribution compartment, it will immediately restart the heat dissipation device to start the heat dissipation process and reduce the temperature in the power distribution compartment. At the same time, the system will restore the previously triggered high temperature alarm and emergency shutdown protection status to ensure that the power distribution compartment can resume normal operation. This step not only helps to eliminate the risk of overheating, but also ensures that the power distribution compartment can quickly and safely restore its original operating state after experiencing a heat event.

[0094] In summary, this embodiment not only improves the flexibility and response speed of the heat dissipation control of the power distribution compartment by adding a series of subsequent steps from S0.4 to S0.7, but also provides a strong guarantee for the recovery and stable operation of the system after encountering the risk of overheating.

[0095] In a more complete and detailed implementation of this embodiment, after S4, a set of heat dissipation stop determination and control processes is added to ensure that the power distribution compartment can stop the operation of the heat dissipation device in a timely and accurate manner after the heat dissipation demand is met, thereby avoiding unnecessary energy consumption and equipment wear. Specifically, after S4, the method further includes:

[0096] S5. When the heat dissipation device is in operation, obtaining at least one ambient temperature in the power distribution compartment, at least one copper busbar temperature, and a total current flowing through the copper busbars.

[0097] It should be noted that when the heat dissipation device is in operation, the system will continuously obtain key environmental data in the power distribution compartment, including at least one ambient temperature reading, at least one copper busbar temperature monitoring value, and the total current of the copper busbar. These data provide the system with an important basis for real-time evaluation of heat dissipation effects and heat dissipation requirements.

[0098] S6. Determine whether at least one of the ambient temperatures reaches a preset first heat dissipation stop temperature, or at least one of the copper busbar temperature reaches a preset second heat dissipation stop temperature, or the total current of the copper busbar reaches a preset heat dissipation stop current; if so, execute S7; if not, return to execute S5.

[0099] It should be noted that based on the continuously acquired environmental data, the system will determine the heat dissipation stop conditions. This includes checking whether at least one ambient temperature has dropped below the preset first heat dissipation stop temperature threshold, or the temperature of at least one copper busbar has dropped below the second heat dissipation stop temperature threshold, or the total current of the copper busbar has decreased to below the preset value of the heat dissipation stop current. These conditions together constitute the basis for determining whether the heat dissipation device stops operating. If any of the above conditions is met, that is, it is judged that the heat dissipation demand of the distribution compartment has been met, the system will enter step S7; if not, the system will return to step S5 and continue to monitor the environmental data until the heat dissipation stop condition is met.

[0100] S7, stopping the heat dissipation device in the power distribution compartment to stop heat dissipation.

[0101] It should be noted that once the system determines that the heat dissipation demand of the power distribution compartment has been met, it will immediately stop the heat dissipation device to stop the heat dissipation process. This step not only helps save energy and reduce operating costs, but also prevents the heat dissipation device from continuing to operate when heat dissipation is not required, thereby extending its service life and reducing equipment failure rate.

[0102] In summary, this embodiment not only achieves precise control of the heat dissipation device by adding a series of subsequent steps from S5 to S7, but also improves the overall energy efficiency and operation stability of the power distribution compartment. This improvement not only helps to reduce operating costs, but also improves the safety and reliability of the power distribution compartment, providing a strong guarantee for the stable operation of the power system.

[0103] In a specific and innovative implementation of this embodiment, the specific type of the heat dissipation device is further clarified, that is, a dual-circulation air duct heat dissipation device is used as a heat dissipation solution for the distribution cabin, which can improve the cabin protection level while ensuring the heat dissipation in the cabin.

[0104] The dual-circulation duct cooling device is an efficient cooling system designed to achieve effective heat transfer and dissipation through two independent duct cycles. Specifically, the system usually includes an internal duct and an external duct. The internal duct is responsible for absorbing heat from the inside of the distribution compartment, while the external duct is responsible for dissipating the absorbed heat to the external environment. This design not only improves the heat dissipation efficiency, but also ensures the uniform distribution of temperature inside the distribution compartment, avoiding local overheating.

[0105] The use of dual-circulation air duct heat dissipation equipment as a heat dissipation device for the power distribution compartment has significant advantages. First, its efficient heat dissipation capacity can ensure that the power distribution compartment can maintain a stable temperature environment under long-term, high-load operation, thereby extending the service life of the equipment and improving the reliability of the system. Secondly, the design of the dual-circulation air duct makes the heat dissipation process more flexible, and the heat dissipation strategy can be dynamically adjusted according to the actual load and temperature changes of the power distribution compartment to achieve optimal energy consumption. Finally, this type of heat dissipation equipment usually has a lower noise level and can provide continuous heat dissipation protection for the power distribution compartment without affecting the work and life of personnel.

[0106] In summary, this embodiment adopts dual-circulation air duct heat dissipation equipment as the heat dissipation device of the distribution cabin, which not only improves the heat dissipation efficiency and stability, but also realizes the optimal control of energy consumption and noise, providing strong technical support for the safe and efficient operation of the distribution cabin.

[0107] In a more specific and advanced implementation of this embodiment, the specific form of the dual-circulation air duct heat dissipation device is clarified, that is, an exchanger or air conditioner is used as a dual-circulation air duct heat dissipation solution for the distribution cabin.

[0108] As a type of dual-circulation air duct heat dissipation equipment, the core of the exchanger is to transfer the heat inside the distribution compartment to the external environment through heat exchange. This type of equipment usually contains two independent fluid circulation systems, one for absorbing the heat inside the distribution compartment and the other for dissipating the heat to the external environment. Through the coordinated work of these two circulation systems, the exchanger can efficiently meet the heat dissipation needs of the distribution compartment while maintaining the stability of the internal temperature.

[0109] On the other hand, air conditioners, as another option for dual-circulation air duct heat dissipation equipment, also have excellent heat dissipation performance. The air conditioner absorbs the heat inside the distribution compartment and converts it into cold energy through the internal refrigeration system, and then releases the cold energy to the external environment through the air duct, thereby achieving the purpose of heat dissipation. Compared with the exchanger, the air conditioner usually has higher performance in terms of heat dissipation efficiency, temperature control accuracy and noise control.

[0110] Using an exchanger or air conditioner as the dual-circulation air duct cooling device of the power distribution compartment not only ensures the efficiency and stability of the cooling process, but also provides more flexible control options. For example, the operation mode and wind speed of the cooling device can be dynamically adjusted according to the actual load and temperature changes of the power distribution compartment to optimize energy consumption. In addition, these cooling devices usually also have intelligent monitoring and alarm functions, which can monitor the operating status of the cooling system in real time and issue alarms in time when faults or abnormal conditions occur, ensuring the safe operation of the power distribution compartment.

[0111] In an accurate and detailed implementation of this embodiment, the specific collection method and the type of sensor used for the ambient temperature, the copper busbar temperature and the total current of the copper busbar are further clarified.

[0112] For the collection of ambient temperature and copper busbar temperature, a temperature and humidity transmitter is used as a temperature sensor. A temperature and humidity transmitter is a sensor that integrates temperature and humidity measurement functions. It can sense and measure the temperature and humidity changes of the surrounding environment in real time through internal sensor elements. In the heat dissipation control system of the distribution cabin, the temperature and humidity transmitter is arranged in a key position to monitor the ambient temperature and copper busbar temperature inside the distribution cabin in real time. This sensor not only has high-precision and high-stability measurement performance, but also can convert the measurement data into a standard signal output, which is convenient for connection with the control system and data transmission.

[0113] For the collection of the total current of the copper busbar, a current sensor is used. A current sensor is a sensor that can measure the current in a circuit. It usually senses the magnetic field generated by the current in a non-contact or contact manner to measure the current. In the distribution compartment, the current sensor is installed on the main line of the copper busbar to monitor the total current of the copper busbar in real time. This sensor has the advantages of a wide measurement range, high accuracy, and fast response speed, and can provide accurate and reliable current data for the heat dissipation control system.

[0114] Although the terms such as distribution compartment and temperature are used more frequently in this application, the possibility of using other terms is not excluded. These terms are used only to more conveniently describe and explain the essence of the present invention; interpreting them as any additional restrictions is contrary to the spirit of the present invention.

[0115] An embodiment of the present invention provides a high-protection distribution cabin heat dissipation control method. By obtaining at least one ambient temperature, at least one copper busbar temperature and the total current of the copper busbar in the distribution cabin, the thermal risk in the distribution cabin can be comprehensively evaluated, thereby accurately controlling the start-up of the heat dissipation device to start heat dissipation. The method is not only timely and accurate, but also can save power consumption and is suitable for large-scale promotion and application.
