Description

Technical Field

[0001] This invention relates to the field of prefabricated substation partition technology, and more particularly to a prefabricated substation partition, temperature control method, device, electronic equipment, and storage medium. Background Technology

[0002] Prefabricated substations, as crucial power distribution equipment in power systems, are widely used in various scenarios such as outdoor environments, industrial parks, and residential communities. Their operational stability directly impacts the security and continuity of power supply. The partition, as the core enclosure component of the prefabricated substation enclosure, primarily undertakes functions such as heat insulation and protection, isolating external environmental interference and providing a stable operating environment for the substation's internal equipment. Therefore, the structural performance and temperature control capabilities of the partition have a significant impact on the long-term reliable operation of the prefabricated substation.

[0003] Currently, existing prefabricated substation partitions mostly adopt traditional color steel sandwich panels and ordinary hollow panels, which have many technical defects and cannot meet the needs of use in complex outdoor environments and the high precision requirements of equipment operation. Specifically, the inner and outer panels of existing partitions are mostly spliced ​​separately, resulting in poor sealing performance at the joints, making them prone to the infiltration of moisture, dust, and corrosive gases. At the same time, there is a lack of effective supporting and reinforcing structures between the panels, resulting in weak overall resistance to bending, compression, and deformation. Under the impact of outdoor forces, the cavity is prone to collapse and the panels may crack, seriously affecting the service life and protective effect of the partition.

[0004] In terms of construction and maintenance, the existing method of assembling the partition is relatively complicated. The splicing process requires complex on-site sealing treatment, which results in long construction period, low efficiency, and problems such as sealing failure in the splicing gaps.

[0005] In terms of fixed structure design, existing partitions mostly adopt rigid fixing methods, which do not take into account the deformation stress caused by outdoor temperature fluctuations and thermal expansion and contraction. After long-term use, this can easily lead to panel cracking and sealing failure. At the same time, the corrosion resistance of the fasteners is insufficient, and electrochemical corrosion is prone to occur in complex outdoor environments, further shortening the service life of the partition.

[0006] In terms of temperature control, most existing prefabricated substations do not have a precise temperature control system for the partitions, or only use simple passive insulation methods. They cannot actively control the internal temperature of the partitions according to the equipment's operating requirements, making it difficult to stabilize the internal temperature within the equipment's suitable operating range. This can easily lead to equipment failure due to temperature deviations and increase manual maintenance costs.

[0007] In summary, existing prefabricated substation partitions suffer from numerous problems, including poor structural stability, insufficient sealing performance, inadequate heat insulation, inconvenient construction and maintenance, low temperature control accuracy, and insufficient economy and practicality. These issues make it difficult to meet the requirements for long-term stable operation of prefabricated substation equipment. Therefore, developing a prefabricated substation partition with optimized structure, superior performance, and convenient operation and maintenance has significant practical significance and application value.

[0008] Therefore, it is necessary to develop and design a method for partitioning and temperature control in a prefabricated substation. Summary of the Invention

Detailed Implementation

[0025] In the following description, specific details such as particular system structures and techniques are set forth for illustrative purposes and not for limitation, so as to provide a thorough understanding of embodiments of the invention. However, those skilled in the art will understand that the invention can be implemented in other embodiments without these specific details. In other instances, detailed descriptions of well-known systems, apparatuses, and methods are omitted so as not to obscure the description of the invention with unnecessary detail.

[0026] To make the objectives, technical solutions, and advantages of the present invention clearer, specific embodiments will be described below in conjunction with the accompanying drawings.

[0027] The embodiments of the present invention will be described in detail below. This example is implemented based on the technical solution of the present invention, and provides detailed implementation methods and specific operation processes. However, the protection scope of the present invention is not limited to the following embodiments.

[0028] like Figure 1-2 As shown, a first aspect of the present invention provides a prefabricated substation partition, comprising: The inner panel 110, the outer panel 120, and at least two air nozzles 130 are integrally formed; The inner panel 110 and the outer panel 120 form a closed cavity, and a supporting rib connecting the inner panel 110 and the outer panel 120 is provided inside the cavity. The air nozzle 130 is connected to the cavity; When one of the air nozzles 130 is connected to the vacuum extraction device and the other air nozzles 130 are closed, a vacuum structure can be formed in the cavity through the vacuum extraction device.

[0029] In one possible implementation, the prefabricated substation partition further includes: a sealing splice; The sealing assembly includes a sealing body 210; The sealing body 210 is provided with an air passage interface on its upper part, and the sealing body 210 is provided with an air passage that communicates with the air passage interface; When the air nozzle 130 is inserted into the air passage interface, the air passage is connected to the cavity.

[0030] In one possible implementation, the prefabricated substation partition also includes: a fastener 140, a bolt 150, and a spring 160; The fastener 140 has an upwardly extending first side plate on its first side, and the first side plate has a mounting hole. The second side of the fastener 140 is provided with a downwardly extending first pressure plate; The fastener 140 is provided with a first hole penetrating the upper and lower surfaces; The spring 160 is sleeved on the cylindrical part of the bolt 150, and the cylindrical part of the bolt 150 passes through the first hole from bottom to top.

[0031] For example, the partition of this prefabricated substation is an integrated sealed structure, the core of which consists of an integrally formed inner panel 110, an outer panel 120 and at least two air nozzles 130, mainly used for heat insulation and structural protection inside the prefabricated substation to ensure the stable operation of the substation equipment.

[0032] The inner panel 110 and the outer panel 120 are integrally molded from high-strength, weather-resistant composite materials. They are arranged in parallel and their edges are seamlessly connected through a sealing structure, forming a hollow cavity with good airtightness. To improve the overall structural rigidity of the partition and prevent the cavity from deforming under negative pressure or external force, several supporting ribs are evenly distributed inside the cavity. The two ends of the supporting ribs are firmly connected to the inner wall of the inner panel 110 and the inner wall of the outer panel 120, respectively, so as to realize the synchronous stress of the inner and outer panels 120. At the same time, the internal space of the cavity is reasonably divided, further optimizing the structural stability.

[0033] The air nozzle 130 is made of corrosion-resistant sealing material and is embedded in the preset mounting position of the inner panel 110 or the outer panel 120. Its internal flow channel completely penetrates the panel wall thickness to ensure a tight connection with the inside of the cavity. The air nozzle 130 is designed in a multi-group layout to meet the operational needs under different working conditions. When one air nozzle 130 is sealed to the vacuum extraction device, and the other air nozzles 130 are sealed with special sealing plugs, the vacuum extraction device can be activated to continuously extract air from the cavity, forming a stable vacuum structure inside the cavity. This significantly improves the heat insulation and sound insulation performance of the partition and reduces the impact of the external environment on the equipment inside the substation.

[0034] Description of the sealing splice structure: In practical applications, to achieve modular assembly of multiple partitions, the box-type substation is equipped with sealing splicing components for each partition. These components have the dual functions of splicing and fixing as well as air passage, ensuring the airtightness of the overall structure after assembly.

[0035] The sealing assembly includes a high-density, weather-resistant sealing body 210, which is manufactured using a one-piece molding process, possessing excellent sealing performance and structural strength. A dedicated air passage interface is pre-installed on the top of the sealing body 210, with sealing grooves on the inner wall of the interface to ensure a tight seal with the air nozzle 130. A through-type air passage is pre-designed inside the sealing body 210, with one end connected to the air passage interface and the other end extending to the splicing surface of the sealing body 210, forming a complete air passage. When the air nozzle 130 of the partition is inserted into the corresponding air passage interface, the outer wall of the air nozzle 130 forms an interference seal with the inner wall of the interface, achieving a sealed connection between the air passage and the cavity. This ensures the overall sealing performance of the assembled multiple partitions and provides a unified air passage interface for vacuum extraction or gas filling of the cavity, improving construction convenience.

[0036] Description of fastener 140 and its matching connection structure: To ensure a secure connection between the partition and the box-type substation frame, and to counteract the deformation stress caused by changes in ambient temperature, the partition is equipped with fasteners 140, bolts 150, and springs 160 to form an elastic fixing structure.

[0037] The fastener 140 is made of corrosion-resistant metal through stamping and has an overall L-shaped structure. Its first side extends vertically upward to form a first side plate, and standard mounting holes are provided on the first side plate for bolting 150 to the steel structure frame of the prefabricated substation enclosure to ensure a firm connection. The second side of the fastener 140 is positioned opposite to the first side and extends vertically downward to form a first pressure plate. The first pressure plate is attached to the edge of the partition panel to vertically limit the panel and prevent it from shifting.

[0038] The fastener 140 has a first hole extending vertically through its upper and lower surfaces, precisely corresponding to the pre-drilled mounting holes on the edge of the partition panel. A spring 160 is coaxially fitted onto the cylindrical portion of a bolt 150. The bolt 150's cylindrical portion passes sequentially from bottom to top through the first hole in the fastener 140 and the pre-drilled mounting holes in the partition panel. A lock nut is fitted to the threaded section at the top of the bolt 150. After tightening the lock nut, the spring 160 is compressed between the first pressure plate of the fastener 140 and the partition panel, forming an elastic preload. This effectively counteracts the deformation stress caused by temperature fluctuations and outdoor thermal expansion and contraction during the operation of the prefabricated substation, preventing the panel from cracking due to rigid connections. It also prevents the cavity sealing performance from failing, extending the service life of the partition.

[0039] The partition of this invention is formed by inner and outer polymer panels and supporting ribs to form an independent and sealed air partition. It serves as a carrier cavity that can switch between vacuum insulation and gas-filled heat exchange. The cavity has good airtightness and no risk of leakage or seepage during long-term use. The supporting ribs can effectively resist vacuum negative pressure and ensure the stability of the cavity structure.

[0040] Figure 3 A flowchart of a temperature control method for a prefabricated substation provided in an embodiment of the present invention.

[0041] like Figure 3 As shown, a flowchart illustrating the implementation of the prefabricated substation temperature control method provided by an embodiment of the present invention is presented, and is described in detail below: In step 301, the sign value representing the adjustment direction of the system is obtained.

[0042] In some implementations, the sign value is determined based on the disturbance compensation amount applied to the first regulating valve, including: Obtain the first initial temperature and the opening degree of the first regulating valve; Multiple first temperatures obtained at preset time intervals are constructed into a first temperature queue; Obtain the second initial temperature and adjust the opening of the first regulating valve according to the disturbance compensation amount; Multiple second temperatures obtained at preset time intervals are constructed into a second temperature queue; Substituting the first temperature queue and the second temperature queue into the heating equation respectively, the heating power of the first system and the heating power of the second system are obtained, wherein the heating power of the first system and the heating power of the second system correspond to the opening of the first regulating valve before and after the superimposed disturbance compensation amount. The difference between the heating power of the second system and the heating power of the first system is taken as the power difference; Multiply the power difference by the disturbance compensation amount to obtain the reference product; The sign of the reference product is used as the sign value.

[0043] In some embodiments, the heating equation is: In the formula, for Temperature at any moment The initial temperature. This refers to the heating power. For thermal resistance, It is a natural constant. This is the heating time constant.

[0044] For example, Figure 7 A schematic diagram of a prefabricated substation with partitions is shown. The partitions provided in the first aspect serve as the outer surface of the prefabricated substation 710. In terms of air supply, these partitions are interconnected via air inlets. For example, the air inlets of multiple partitions are divided according to their air intake and exhaust functions, with air intake nozzles connected in parallel and exhaust nozzles connected in parallel, thereby enabling temperature control of the internal operating environment of the substation 710 through the vacuum chamber structure of the partitions.

[0045] Specifically, in order to achieve precise temperature control inside the partition of the prefabricated substation and ensure the stability of the substation equipment operating environment, a temperature regulation and control system is designed based on the vacuum cavity structure of the partition. This system controls the vacuum level and gas flow rate inside the partition to enable the partition to achieve the effects of heat insulation and / or heat dissipation. Figure 4 A schematic diagram of a gas path based on a partition structure is shown. In the diagram, the first gas nozzle of partition 201 is connected to throttle valve 203 (first regulating valve), while the other gas nozzle is connected to vacuum pump 202 via a one-way valve. Throttle valve 203 is typically a needle valve; by adjusting the opening of throttle valve 203, the vacuum level within the partition and the flow rate of gas flowing through it can be adjusted. This allows for relatively precise control of the internal temperature of the substation partition based on the external air temperature.

[0046] Its core regulation process includes the following steps, which work together to achieve dynamic balance control of temperature.

[0047] Obtain the sign value representing the adjustment direction of the system: The sign value is a core parameter for determining the direction of temperature regulation, used to clarify the opening trend (increase or decrease) of the first regulating valve. It is obtained based on a disturbance compensation test of the first regulating valve, determined by comparing the changes in system heat generation power before and after the disturbance. The specific implementation process is as follows: First, when the system is in a stable operating state, the first initial temperature inside the current compartment (i.e., the reference temperature when no disturbance compensation is applied) is collected, and the opening degree of the first regulating valve at this time is recorded as the reference parameter for subsequent comparison. Then, according to the preset time node interval (the interval length can be set according to the actual operating requirements, usually 0.5-30s), the first temperature data inside multiple compartments is continuously collected, and they are constructed into the first temperature queue according to the collection time sequence to characterize the temperature change law of the system when no disturbance is applied.

[0048] Subsequently, the second initial temperature after applying the disturbance compensation amount is collected. At the same time, according to the preset disturbance compensation amount (set based on the system temperature control accuracy requirements, usually 5%-10% of the maximum valve opening), the opening of the first regulating valve is adjusted to bring the system into the operating state after the disturbance. Similarly, according to the preset time intervals mentioned above, the second temperature data inside multiple compartments are continuously collected and constructed into a second temperature queue according to the collection time sequence, which is used to characterize the temperature change law of the system after the disturbance is applied.

[0049] Substituting the constructed first and second temperature queues into the preset temperature rise equation, the heating power of the first system (corresponding to the opening degree of the first regulating valve before the added disturbance compensation) and the heating power of the second system (corresponding to the opening degree of the first regulating valve after the added disturbance compensation) are calculated respectively. The temperature rise equation is as follows: In the formula, for The internal temperature of the partition at any given time, in °C; The initial temperature (i.e., the first initial temperature or the second initial temperature) is expressed in °C. The system heat output power, measured in W, is the core parameter characterizing the system's heat generation capacity. The system thermal resistance is expressed in °C / W and is determined by parameters such as the properties of the insulation material and the cavity structure. Since the vacuum level of the insulation layer in this system is variable, it needs to be determined by combining multiple sets of data: the first temperature queue and the second temperature queue with the heating equation. It is a natural constant (with a value of approximately 2.718); This is the heating time constant, in units of... The temperature is determined by the system's thermal inertia, based on the vacuum degree of the insulation layer and the thermal conductivity of the material. Similarly, since the vacuum degree of the insulation layer in this system is variable, it needs to be determined by multiple sets of data: the first temperature queue and the second temperature queue combined with the heating equation.

[0050] The difference between the heating power of the second system and the heating power of the first system is calculated to obtain the power difference, which reflects the degree of influence of the disturbance compensation on the system's heat generation capacity. The power difference is multiplied by the applied disturbance compensation to obtain the reference product. The sign (positive or negative) of the reference product is the sign value representing the system's adjustment direction, where a positive sign indicates that the adjustment direction is to increase the valve opening, and a negative sign indicates that the adjustment direction is to decrease the valve opening.

[0051] For example, assuming the preset disturbance compensation is positive (i.e., increasing the opening of the first regulating valve), if the calculated reference product is positive, it means that increasing the valve opening can increase the system's heat generation power. The corresponding scenario may be that the internal temperature of the substation is low, while the external temperature is high, and the partition receives more external heat radiation. The corresponding temperature adjustment direction is to increase the opening. If the reference product is negative, it means that increasing the valve opening will reduce the system's heat generation power. The corresponding scenario may be that the internal temperature of the substation is high, the external temperature is low, and the partition receives less external heat radiation. The corresponding temperature adjustment direction is to decrease the opening. The sign value provides a clear directional guide for subsequent valve opening adjustments.

[0052] In step 302, multiple first temperature differences are determined based on the current temperature, multiple historical temperatures, and the target temperature. Each first temperature difference corresponds to a current temperature or a historical temperature, and the first temperature difference characterizes the deviation between the target temperature and the historical temperature or the current temperature.

[0053] In step 303, with the target temperature as the target, the opening of the first regulating valve is adjusted according to the symbol value and the plurality of first temperature differences. In this case, one or more air nozzles of the box-type substation partition are connected to a vacuum pumping device, the remaining air nozzles of the box-type substation partition are connected to the first end of the first regulating valve, and the second end of the first regulating valve is open to the atmosphere.

[0054] In some embodiments, adjusting the opening of the first regulating valve based on the target temperature, the sign value, and the plurality of first temperature differences includes: Based on the first formula, the time interval, and the plurality of first temperature differences, a first coefficient, a second coefficient, and a third coefficient are determined, wherein the time interval is the interval between two adjacent time nodes, and the first formula is: In the formula, , as well as These are the first coefficient, the second coefficient, and the third coefficient, respectively. This is the proportionality coefficient. The integral coefficient is... These are the differential coefficients. The time interval is a time node; Substituting the sign value, the first coefficient, the second coefficient, and the third coefficient into the control valve opening compensation equation, the valve opening compensation amount is obtained, wherein the control valve opening compensation equation is: In the formula, This is the valve opening compensation amount. For the first The first temperature difference at each time point For sign values; Adjust the opening of the first regulating valve according to the valve opening compensation amount.

[0055] For example, after obtaining the sign value, the adjustment range needs to be further clarified based on the temperature deviation data. Specifically, multiple first temperature differences need to be calculated based on the current temperature of the interlayer, multiple historical temperatures, and a preset target temperature. Among them, the target temperature is preset according to the operating requirements of the prefabricated substation equipment (usually 15-35℃), and the historical temperatures are temperature data collected at the preset time intervals before the current temperature. The number of historical temperatures can be set according to the control accuracy requirements (usually 3-5).

[0056] Each first temperature difference corresponds to a current temperature or a historical temperature. Its core characteristic is the deviation between the preset target temperature and the corresponding temperature (historical or current temperature). The calculation logic is: First temperature difference = Target temperature - Corresponding temperature (historical or current temperature). When the first temperature difference is positive, it indicates that the corresponding temperature is lower than the target temperature, and the system temperature needs to be increased by adjusting the valve opening. When the first temperature difference is negative, it indicates that the corresponding temperature is higher than the target temperature, and the system temperature needs to be decreased by adjusting the valve opening. When the first temperature difference is zero, it indicates that the corresponding temperature is the same as the target temperature, and the system is in a stable state.

[0057] The opening degree of the first regulating valve is adjusted based on the sign value and the first temperature difference: This invention uses a preset target temperature as the core of regulation, and combines the acquired sign value (regulation direction) and calculated multiple first temperature differences (regulation amplitude basis) to precisely adjust the opening of the first regulating valve, thereby achieving dynamic balance of the internal temperature of the partition. Specifically, the connection relationship of the partition in the prefabricated substation must meet the following requirements: one or more air nozzles are sealed and connected to a vacuum pumping device to maintain or regulate the vacuum level of the cavity; the remaining air nozzles of the partition are sealed and connected to the first end of the first regulating valve, while the second end of the first regulating valve is open to the atmosphere. By adjusting the opening of the first regulating valve, the flow rate of air into the partition cavity can be controlled, thereby regulating the internal temperature of the cavity (increasing the amount of air entering reduces the cavity vacuum level and improves thermal conductivity, achieving cooling when the external temperature is low and heat radiation is low, and heating when the external temperature is high and heat radiation is high; decreasing the amount of air entering increases the cavity vacuum level and reduces thermal conductivity, achieving heat preservation or heating when the external temperature is low and heat radiation is low, and heat insulation or cooling when the external temperature is high and heat radiation is high).

[0058] In the specific implementation process, the opening adjustment based on the target temperature can be divided into the following three sub-steps: The first step is to determine the adjustment coefficient. Based on the first formula, the preset time interval, and multiple first temperature differences, the first coefficient is determined through simultaneous calculations. ), second coefficient ( ) and the third coefficient ( The time interval is the time difference between two adjacent temperature acquisition time points, and the first formula is: In the formula, , , These are the first coefficient, the second coefficient, and the third coefficient, all of which are dimensionless coefficients. This is a proportionality coefficient used to adjust the response speed of temperature deviation, with a value range of 0.5-2.0, calibrated according to the required control accuracy. This is the integral coefficient, used to eliminate steady-state temperature error, with a value range of 0.01-0.1 to avoid integral saturation; This is the differential coefficient, used to suppress temperature fluctuations, with a value ranging from 0.1 to 1.0, to improve system stability; The time interval is in seconds.

[0059] The second step is to calculate the valve opening compensation amount. The obtained sign value ( The first coefficient obtained from the first step ( ), second coefficient ( ) and the third coefficient ( Substituting the values ​​into the preset regulating valve opening compensation equation, the valve opening compensation amount is calculated. This compensation amount is used to determine the specific adjustment range of the first regulating valve, and the regulating valve opening compensation equation is: In the formula, This is the valve opening compensation amount, expressed as a percentage (relative to the maximum valve opening). For the first The first temperature difference at each time point (i.e., the temperature difference corresponding to the current temperature), in °C; For the first The first temperature difference at each time point (i.e., the temperature difference corresponding to the most recent historical temperature), in °C; For the first The first temperature difference at each time point (i.e., the temperature difference corresponding to the second most recent historical temperature), in °C; The sign value (takes a value of +1 or -1) is used to control the direction of the opening compensation amount (positive value increases the opening, negative value decreases the opening).

[0060] The third step is to perform valve opening adjustment. Based on the calculated valve opening compensation, the current opening of the first regulating valve is adjusted. The adjustment logic is: current valve opening + valve opening compensation = adjusted valve opening. After adjustment, the internal temperature data of the partition is continuously collected, and the above steps are repeated to form a closed-loop control, ensuring that the internal temperature of the partition remains stable within the preset target temperature range, thus providing a stable operating environment for the prefabricated substation equipment.

[0061] The present invention provides an embodiment of a temperature control method for a prefabricated substation. First, a sign value representing the system's adjustment direction is obtained. Then, based on the current temperature, multiple historical temperatures, and a target temperature, multiple first temperature differences are determined, where each first temperature difference corresponds to a current temperature or a historical temperature, and the first temperature difference represents the deviation between the target temperature and the historical temperature or the current temperature. Finally, with the target temperature as the objective, the opening of a first regulating valve is adjusted according to the sign value and the multiple first temperature differences. One or more air nozzles in the prefabricated substation compartment are connected to a vacuum pump, the remaining air nozzles in the prefabricated substation compartment are connected to a first end of the first regulating valve, and the second end of the first regulating valve is open to the atmosphere.

[0062] This prefabricated substation partition, through optimized structural design and coordinated temperature control system, offers several significant advantages over traditional prefabricated substation partitions, effectively improving the stability, reliability, and economy of substation operation. Specifically: Firstly, its excellent structural stability and sealing performance provide a solid foundation for equipment protection. The inner and outer panels of the partition are integrally molded from high-strength, weather-resistant composite materials with seamless edge sealing. Combined with the evenly distributed support ribs inside the cavity, this not only significantly improves the overall bending, compressive, and deformation resistance of the partition, effectively resisting outdoor impacts and cavity collapse under negative pressure, but also ensures the airtightness of the hollow cavity, preventing the entry of external moisture, dust, and corrosive gases. At the same time, the separation effect of the support ribs further optimizes the structural stress and extends the outdoor service life of the partition.

[0063] Secondly, it boasts outstanding thermal insulation performance, ensuring a safe operating environment for equipment. Through the combination of a multi-nozzle design and a vacuum extraction device, a stable vacuum structure can be formed in the partition cavity. Combined with the thermal insulation properties of the high-strength composite material itself, the thermal insulation efficiency is improved by more than 30% compared to traditional non-vacuum partitions. It can effectively isolate external environmental temperature fluctuations and avoid the impact of high and low temperatures on the internal equipment of the substation. At the same time, the vacuum structure can significantly reduce sound wave transmission and reduce the interference of equipment operating noise.

[0064] Thirdly, modular assembly is convenient, reducing construction and maintenance costs. The sealing splice has dual functions of splicing and fixing as well as air passage conduction. It can realize the rapid modular assembly of multiple partitions without complicated on-site sealing treatment, which significantly shortens the construction period. At the same time, it can ensure the airtightness of the overall structure after assembly and avoid vacuum leakage caused by splicing gaps. Meanwhile, the multi-air nozzle layout and the air passage design of the sealing splice facilitate the later detection, replenishment and maintenance of the cavity vacuum level without disassembling the entire partition structure, reducing maintenance workload and costs.

[0065] Fourth, the flexible fixing structure is scientifically designed and adaptable to complex outdoor environments. The flexible fixing structure, composed of fasteners, bolts, and springs, uses the preload of the springs to offset the deformation stress caused by temperature fluctuations and outdoor thermal expansion and contraction during the operation of the prefabricated substation. This avoids problems such as cracking and sealing failure of the partition panels due to rigid connections. At the same time, the corrosion-resistant metal fasteners can effectively resist outdoor electrochemical corrosion, further improving the environmental adaptability of the partition and meeting the outdoor operation requirements under different climatic conditions.

[0066] Fifth, precise and efficient temperature control ensures stable equipment operation. The integrated temperature regulation and control system accurately determines the adjustment direction through sign values ​​and calculates valve opening compensation by combining multiple temperature differences and adjustment coefficients. This achieves closed-loop precise control of the internal temperature of the partition, stabilizing the temperature within the required 15-25℃ range for equipment operation. This effectively avoids problems such as insulation aging and operational failures caused by excessively high or low temperatures, improving the operational reliability and service life of substation equipment. At the same time, the control process is highly automated, requiring no manual intervention and reducing manual maintenance costs.
