[0014] The present application embodiment provides an adaptive temperature control method for a power distribution cabinet, such as Figure 1 As shown, the method includes: Step S100, obtain multiple insulation protection frames set in the power distribution cabinet, wherein each insulation protection frame is configured with a corresponding temperature control and adjustment module, and each insulation protection frame is configured with an independent temperature control device, and the temperature control and adjustment module performs temperature adjustment by controlling the temperature control device. Specifically, multiple insulation protection frames are set in the power distribution cabinet. First, the number and specifications of the protection frames should be determined according to the working environment of the power distribution cabinet, the type and power of the electrical equipment carried, etc., and reasonable arrangements should be made considering the spatial layout. Then, suitable insulation materials are selected to make the protection frames to ensure that they have good thermal insulation performance, are durable and have good sealing. Then, a suitable temperature control and adjustment module is selected for each insulation protection frame. The module should have an accurate temperature measurement function, a flexible control algorithm and a reliable output interface. After installation, it is debugged and calibrated to accurately measure the temperature in the protection frame and control it according to the preset range. At the same time, for different protection frames, independent temperature control devices such as fans, heaters, refrigerators, etc. are selected according to the temperature control requirements, installed in the protection frame and connected to the temperature control and adjustment module. The temperature control and adjustment module monitors the temperature inside the protection frame in real time through built-in or external temperature sensors, and transmits the data to the processor for analysis and processing. If the temperature exceeds the preset range, a control signal is issued to start the corresponding temperature control device for adjustment. The device operating parameters can be adjusted according to actual conditions, and the temperature change trend can be predicted and adjusted in advance. During the operation of the temperature control device, the module continues to monitor temperature changes and adjust the control strategy based on feedback information. If the effect is not ideal, the parameters can be adjusted or other measures can be taken. Regular maintenance and inspection are required to continuously optimize the temperature control strategy and parameters to improve the temperature control performance and reliability of the distribution cabinet.

[0015] Step S200, obtain the corresponding real-time temperature monitoring data sets in the multiple insulation protection frames, and obtain the first insulation protection frame to be adjusted according to the real-time temperature monitoring data sets. Specifically, obtain the corresponding real-time temperature monitoring data sets in the multiple insulation protection frames, install a high-precision temperature sensor in each insulation protection frame, and transmit the data to the central control system in real time for sorting and storage. Based on the data set, first set the temperature threshold range, and then compare the real-time temperature of each protection frame with the threshold range. At the same time, comprehensively consider factors such as the temperature change rate and the temperature difference with adjacent protection frames, and finally determine the first insulation protection frame to be adjusted that needs temperature adjustment. The protection frame has the highest temperature, changes the fastest, or has the greatest impact on the temperature stability of the distribution cabinet. After determination, temperature adjustment measures can be taken for it, and other protection frames also need to continue to be monitored and analyzed to prevent new temperature anomalies.

[0016] Step S300, obtain the position distribution information of the multiple insulation protection frames, and obtain the identification insulation protection frame of the first insulation protection frame to be adjusted according to the position distribution information, wherein the identification insulation protection frame is a protection frame whose influence degree of heat conduction is greater than the preset influence degree. Specifically, firstly, the inside of the power distribution cabinet is accurately measured and the layout is analyzed to obtain the position distribution information such as the three-dimensional position coordinates, adjacent distances, design dimensions and relative arrangement relationships of multiple insulation protection frames. Then, a heat conduction influence degree calculation model is constructed based on this information, and the convolution features are defined separately in contact and non-contact types. With the first insulation protection frame to be adjusted as the center, a calculation frame group with other protection frames is established, and the model is called to calculate the heat conduction influence degree for each frame group. The contact type uses a specific expression, and the non-contact type also has a corresponding expression. Finally, the protection frame with a greater than preset influence degree is selected from the calculated multiple influence degrees, which is the identification insulation protection frame of the first insulation protection frame to be adjusted. These protection frames are greatly affected by heat conduction and need special attention in temperature regulation.

[0017] In a possible implementation, position distribution information of the multiple insulation protection frames is obtained, and according to the position distribution information, an identification insulation protection frame of the first insulation protection frame to be adjusted is obtained, wherein the identification insulation protection frame is a protection frame whose degree of influence by heat conduction is greater than a preset degree of influence, and step S300 further includes step S310, obtaining the position distribution information, wherein the position distribution information includes the three-dimensional position coordinates of the insulation protection frame, the distance between adjacent insulation protection frames, the design size of the insulation protection frame, and the relative arrangement relationship of the protection frames. Specifically, first, it is necessary to accurately measure and analyze the multiple insulation protection frames in the distribution cabinet to obtain position distribution information. The three-dimensional position coordinates of the insulation protection frame can be determined by using three-dimensional measurement tools or sensor-based positioning technology to clarify the specific spatial position of each protection frame in the distribution cabinet. The distance between adjacent insulation protection frames can be obtained by direct measurement or based on coordinate calculation. Understanding the spacing between protection frames is crucial for analyzing heat conduction. The design dimensions of the insulation protection frame include parameters such as up and down, left and right, front and back length, width and height. The size information determines the spatial size and shape of the protection frame, and also affects the distribution and conduction of heat therein. The relative arrangement relationship of the protection frame describes the relative position and direction of each protection frame in the distribution cabinet, such as which protection frame is above, below, left or right of which protection frame, etc. By obtaining detailed position distribution information, basic data is provided for the subsequent construction of a heat conduction influence calculation model.

[0018] Step S320, constructing a heat conduction influence calculation model according to the position distribution information. Specifically, based on the position distribution information, a heat conduction influence calculation model is constructed, the purpose of the model is to quantify the degree of heat conduction between different protection frames, considering that the main modes of heat conduction are contact conduction and non-contact conduction (such as thermal radiation and air convection, etc.), wherein for the contact heat conduction influence calculation model, the contact convolution features are determined to include the distance between the two protection frames, the thermal conductivity of the contact surface, the contact area, and the temperature difference between the two protection frames, wherein for the non-contact heat conduction influence calculation model, the non-contact convolution features are determined to include the distance between the two protection frames, the air thermal conductivity of the two protection frames, and the temperature difference between the two protection frames, considering the contact and For non-contact conduction, the final heat conduction influence can be set as the sum of the two. The model needs to consider multiple factors comprehensively. For contact conduction, factors such as the distance between adjacent protection frames, the thermal conductivity of the contact surface, and the contact area will affect the intensity of heat conduction. For non-contact conduction, factors such as the distance between protection frames, air thermal conductivity, and temperature difference play an important role. Based on the above factors, a mathematical model is established. By inputting relevant parameters of the protection frames, such as position coordinates, distance, thermal conductivity, area, and temperature difference, the heat conduction influence between the two protection frames can be output. The model is verified and adjusted through actual measurement data to improve its accuracy and reliability.

[0019] Step S330, establish N calculation frame groups of the first insulation protection frame to be adjusted and other insulation protection frames, call the heat conduction influence calculation model to calculate each calculation frame group, and output N heat conduction influences. Specifically, establish N calculation frame groups of the first insulation protection frame to be adjusted and other insulation protection frames, take the first insulation protection frame to be adjusted as the center, and form a calculation frame group with each other protection frame to obtain N calculation frame groups. Then, call the constructed heat conduction influence calculation model to calculate each calculation frame group, input the relevant parameters of the two protection frames in each calculation frame group into the model, the model will calculate according to the preset algorithm and formula, and output a heat conduction influence value. After calculating the N calculation frame groups, N heat conduction influences will be obtained, and automatic calculation can be realized by programming to improve calculation efficiency and accuracy.

[0020] Step S340, screening out the protection frames with a greater than preset influence degree from the N heat conduction influence degrees as the identification insulation protection frames. Specifically, screening out the protection frames with a greater than preset influence degree from the N heat conduction influence degrees, and determining them as the identification insulation protection frames. The preset influence degree can be set according to actual needs and experience, and it represents a threshold. When the heat conduction influence degree between two protection frames is greater than this threshold, it means that the heat conduction between the two protection frames is more significant and needs special attention. Through screening, it can be determined which protection frames are greatly affected by the heat conduction of the first insulation protection frame to be adjusted. The protection frame is the identification insulation protection frame. In the subsequent temperature adjustment process, the identification insulation protection frame needs to be adjusted synchronously to prevent them from having an adverse effect on the temperature adjustment of the first insulation protection frame to be adjusted.

[0021] In a possible implementation, a heat conduction influence calculation model is constructed according to the position distribution information, and step S320 further includes step S321, wherein the heat conduction influence calculation model includes a contact-heat conduction influence calculation model and a non-contact-heat conduction influence calculation model. Specifically, it is first clarified that the heat conduction influence calculation model includes two types: contact and non-contact. In the power distribution cabinet, the heat conduction between the insulation protection frames is carried out by direct contact or non-contact. Therefore, different calculation models need to be established to accurately evaluate the influence of heat conduction. The existence of the two models can more comprehensively consider various possible heat transfer pathways and improve the analysis accuracy of heat conduction between insulation protection frames.

[0022] Step S322, defining the contact convolution features of the contact-heat conduction influence calculation model, wherein the contact convolution features include the distance between the two protection frames, the thermal conductivity of the contact surfaces of the two protection frames, the contact areas of the two protection frames, and the temperature difference between the two protection frames. Specifically, for the contact-heat conduction influence calculation model, its contact convolution features include the distance between the two protection frames, the thermal conductivity of the contact surface of the two protection frames, the contact area of ​​the two protection frames and the temperature difference between the two protection frames, among which the distance between the two protection frames refers to the shortest distance between the two protection frames at the contact position. The size of the distance will affect the intensity of heat conduction. Generally speaking, the closer the distance, the easier it is for heat conduction to occur; the thermal conductivity of the contact surface of the two protection frames is a parameter to measure the ability of the two protection frames to transfer heat on the contact surface. The thermal conductivity of the contact surface of different materials is different, which depends on the properties of the material and the tightness of the contact; the contact area of ​​the two protection frames, the larger the contact area, the more heat conduction pathways there are, and the total amount of conduction will increase accordingly; the temperature difference between the two protection frames, the temperature difference is the driving force of heat conduction, the larger the temperature difference, the greater the speed and intensity of heat conduction.

[0023] Step S323, defining the non-contact convolution features of the non-contact heat conduction influence calculation model, wherein the non-contact convolution features include the distance between the two protection frames, the air thermal conductivity of the two protection frames, and the temperature difference between the two protection frames. Specifically, for the non-contact heat conduction influence calculation model, its non-contact convolution features include the distance between the two protection frames, the air thermal conductivity of the two protection frames, and the temperature difference between the two protection frames, wherein the distance between the two protection frames is similar to the contact type, and the distance refers to the spatial distance between the two protection frames. The size of the distance will affect the intensity of non-contact heat conduction. Generally speaking, the closer the distance, the greater the influence of non-contact conduction methods such as thermal radiation and air convection; the air thermal conductivity of the two protection frames, the air thermal conductivity is a parameter to measure the ability of air to transfer heat, which is affected by factors such as air temperature, humidity, and pressure. The temperature difference between the two protection frames is also the driving force of heat conduction. The greater the temperature difference, the more obvious the trend of non-contact heat conduction will be.

[0024] In a possible implementation, a contact convolution feature of the contact-heat conduction influence calculation model is defined, and the contact convolution feature includes the distance between the two protection frames, the contact surface thermal conductivity of the two protection frames, the contact area of ​​the two protection frames, and the temperature difference between the two protection frames. Step S322 further includes step S3221, calculating each calculation frame group according to the contact convolution feature, and the expression is: ; in, is the heat conduction influence between the insulation protection frame i and the insulation protection frame j, is the thermal conductivity of the contact surface between the insulation protection frame i and the insulation protection frame j, is the contact area between the thermal insulation protection frame i and the thermal insulation protection frame j, is the temperature difference between the insulation protection frame i and the insulation protection frame j, is the distance between the insulation protection frame i and the insulation protection frame j. Specifically, when calculating the heat conduction influence between the insulation protection frame i and the insulation protection frame j, First, we need to clarify the calculation formula The meaning of each parameter in. Among them, It indicates the thermal conductivity of the contact surface between the two protection frames. It depends on the material properties of the contact part and can be determined by experimental measurement or by referring to the material manual. If the contact part is composed of multiple materials, the weighted average method can be used for calculation. Represents the contact area, the size of which directly affects the total amount of heat conduction. It can be measured or estimated based on the design dimensions. The actual contact part must be accurately determined to avoid including the non-contact area. It is the temperature difference between the two protection frames, which is the driving force for heat conduction. It is obtained by installing temperature sensors in the two protection frames to measure their respective temperatures and then subtracting them. Refers to the distance between two protective frames. In contact heat conduction, it is mainly the shortest distance of the contact part. It can be determined by measuring tools or based on position information. Substitute the determined parameter values ​​into the formula and calculate , and The product of the heat transfer potential is obtained by dividing by the distance In order to consider the influence of distance on heat conduction, each pair of contacting insulation protection frames is calculated to obtain multiple heat conduction influence values, which provide a basis for subsequent temperature adjustment and optimization.

[0025] In a possible implementation, a non-contact convolution feature of the non-contact heat conduction influence calculation model is defined, and the non-contact convolution feature includes the distance between two protection frames, the air thermal conductivity of the two protection frames, and the temperature difference between the two protection frames. Step S323 further includes step S3231, calculating each calculation frame group according to the non-contact convolution feature, and the expression is: ;in, is the heat conduction influence between the insulation protection frame i and the insulation protection frame j, is the thermal conductivity of the air between the insulation protection frame i and the insulation protection frame j, is the temperature difference between the insulation protection frame i and the insulation protection frame j, is the distance between the insulation protection frame i and the insulation protection frame j. Specifically, when calculating the non-contact heat conduction influence between the insulation protection frame i and the insulation protection frame j, When the calculation formula is clear The meaning of each parameter in. It indicates the thermal conductivity of the air between the two protection frames. It is affected by factors such as air temperature, humidity, and pressure. It can be determined by referring to a physics manual or experimental data, and adjusted according to the actual environment of the distribution cabinet. Represents the temperature difference between the two protection frames, which is the driving force for heat conduction. It is obtained by installing temperature sensors in the two protection frames and measuring their respective temperatures and then subtracting them. Refers to the distance between two protective frames. In non-contact heat conduction, the longer the distance, the more difficult the heat conduction is. It can be determined by measuring tools or based on position information. Substitute the determined parameter values ​​into the formula and calculate and The product of the theoretically possible heat transfer under a given air thermal conductivity and temperature difference, divided by the distance A certain power reflects the influence of distance on non-contact heat conduction. As the distance increases, the influence of heat conduction gradually decreases. Calculate each pair of non-contact insulation protection frames to obtain multiple non-contact heat conduction influence values ​​to understand the non-contact heat transfer in the distribution cabinet and provide a basis for subsequent temperature adjustment strategies.

[0026] Step S400, perform synchronous temperature adjustment according to the temperature control adjustment modules corresponding to the first insulation protection frame to be adjusted and the identification insulation protection frame. Specifically, the temperature of the first insulation protection frame to be adjusted and the identification insulation protection frame are synchronously adjusted. The first insulation protection frame to be adjusted is determined by the real-time temperature monitoring data set, and the identification insulation protection frame is determined according to the position distribution information. The temperature control adjustment module of each insulation protection frame adjusts the temperature by controlling an independent temperature control device. The modules of the two special protection frames need to assume more important tasks. Before performing synchronous temperature adjustment, the heat conduction relationship between them needs to be analyzed. It can be determined based on the influence of heat conduction, and the conduction direction and intensity are understood to formulate effective strategies. For example, if the identification insulation protection frame has a great impact on the first frame to be adjusted, its temperature should be lowered first. Next, determine the synchronous adjustment target, determine the specific temperature value range or relatively stable state according to the working requirements and safety standards of the distribution cabinet, and then coordinate the work of the temperature control and adjustment modules of each protection frame through the central control system or distributed control network. According to the synchronous adjustment target and the coordinated control instructions, the module adjusts the corresponding temperature control equipment parameters. These two frames may need to be adjusted more frequently. During the temperature synchronous adjustment process, the temperature changes are continuously monitored, and the temperature sensor provides real-time feedback information. The system judges the adjustment effect based on the feedback and adjusts the strategy and parameters in time. If it is not ideal, the conduction relationship can be re-analyzed, the target can be adjusted, or the module working mode can be optimized.

[0027] In a possible implementation, the temperature is synchronously adjusted according to the temperature control adjustment modules corresponding to the first insulation protection frame to be adjusted and the identification insulation protection frame, and step S400 further includes step S410, constructing an influence association matrix according to the heat conduction influence between the identification insulation protection frames. Specifically, first, the influence association matrix is ​​constructed according to the heat conduction influence between the identification insulation protection frames. The identification insulation protection frame is a protection frame whose heat conduction influence is greater than the preset influence. The heat conduction relationship between them is crucial for the temperature synchronization adjustment. The number of identification insulation protection frames is determined to be n. For each pair of identification insulation protection frames i and j, according to the heat conduction influence calculated previously, , construct an n×n matrix A, where , represents the influence of heat conduction of thermal insulation protection frame i on thermal insulation protection frame j. This matrix reflects the heat conduction relationship between thermal insulation protection frames, that is, the influence of temperature change of one protection frame on other protection frames.

[0028] Step S420, based on the goal of minimizing the sum of the heat conduction influences of the identified insulation protection frames, a temperature synchronization adjustment module is constructed to obtain the initial synchronization temperature control parameters corresponding to the first insulation protection frame to be adjusted and the identified insulation protection frame. Specifically, the temperature synchronization adjustment module is constructed with the goal of minimizing the sum of the heat conduction influences of the identified insulation protection frames. The goal is to reduce the heat conduction between the identified insulation protection frames by adjusting the temperature control parameters, thereby achieving synchronous temperature adjustment. The goal is defined as making the sum of the heat conduction influences between all the identified insulation protection frames as small as possible. Through the optimization method, a set of optimal temperature setting values ​​is found. The goal can be understood as making the heat conduction between each protection frame as small as possible, so that the temperature of the entire system is more stable. A temperature synchronization adjustment module is constructed. The module can use a specific optimization algorithm, such as gradually adjusting the temperature setting value, trying different combinations of operating power of the temperature control device, etc., to solve the optimal temperature value. Through the module, the initial synchronization temperature control parameters corresponding to the first insulation protection frame to be adjusted and the identified insulation protection frame can be obtained. The parameters include the preliminarily determined temperature setting value, the approximate power of the temperature control device, etc., which are the basis for achieving temperature synchronization adjustment.

[0029] Step S430, optimize the initial synchronous temperature control parameters according to the influence association matrix, and output the optimized synchronous temperature control parameters. Specifically, the initial synchronous temperature control parameters are optimized according to the influence association matrix, and the influence association matrix reflects the heat conduction relationship between the identification insulation protection frames. The matrix can be used to further adjust the temperature control parameters to improve the effect of temperature synchronization regulation. Some constraints are set based on the influence association matrix. For example, for any two identification insulation protection frames, their temperature difference is required to be within a certain range. The constraints can prevent excessive temperature differences from causing excessive heat conduction, thereby making the system more stable. The initial synchronous temperature control parameters are adjusted and optimized again using the optimization algorithm. The influence association matrix and the constraints are comprehensively considered to obtain more optimized synchronous temperature control parameters. The parameters can more accurately reflect the heat conduction relationship between the identification insulation protection frames and the requirements of temperature synchronization regulation.

[0030] Step S440: the first to-be-adjusted insulation protection frame and the identified insulation protection frame synchronously adjust the temperatures of the temperature control adjustment modules respectively corresponding to the first to-be-adjusted insulation protection frame according to the optimized synchronous temperature control parameters. Specifically, the first insulation protection frame to be adjusted and the identification insulation protection frame perform temperature synchronous adjustment on the corresponding temperature control adjustment modules according to the optimized synchronous temperature control parameters to ensure that the temperature in the power distribution cabinet is maintained within a safe and stable range. If the first insulation protection frame to be adjusted performs a heat dissipation operation, since the heat will be transmitted to the identification insulation protection frame, in order to prevent its temperature from rising, the temperature control device of the identification insulation protection frame may need to take measures to enhance heat dissipation, such as increasing the fan speed, increasing the heat sink area, etc., or starting the cooling device in advance. If the first insulation protection frame to be adjusted performs a heating operation, in order to prevent the temperature of the identification insulation protection frame from being affected and overcooling or overheating, it may be necessary to slow down the heating speed, such as reducing the heater power, or adjust the cooling power, such as adjusting the running time of the cooling device, etc. By continuously monitoring the temperature changes, the temperature control adjustment module is adjusted in real time according to the optimized synchronous temperature control parameters to achieve synchronous temperature adjustment of the first insulation protection frame to be adjusted and the identification insulation protection frame to ensure that the temperature in the power distribution cabinet is always within an appropriate range.

[0031] In one possible implementation, based on the goal of minimizing the sum of the heat conduction influences of the identified insulation protection frame, a temperature synchronization adjustment module is constructed to obtain initial synchronization temperature control parameters corresponding to the first insulation protection frame to be adjusted and the identified insulation protection frame, respectively. Step S420 further includes step S421, obtaining a target adjustment temperature range of the first insulation protection frame to be adjusted. Specifically, determine the target adjustment temperature range of the first insulation protection frame to be adjusted. The range is usually determined based on the working requirements and safety standards of the electrical equipment installed in the distribution cabinet. Analyze the technical specifications of the electrical equipment to understand its normal operating temperature range. For example, some precision electronic equipment may need to work within a relatively low and stable temperature range, while some high-power equipment may be allowed to operate at a slightly higher temperature, but it cannot exceed a certain upper limit. Consider the environmental factors of the distribution cabinet, such as ambient temperature, ventilation conditions, etc. If the distribution cabinet is in a high temperature environment, it is necessary to set the target adjustment temperature range of the first insulation protection frame to be adjusted to a relatively low level to ensure the normal operation and life of the electrical equipment. Use a temperature sensor to monitor the temperature in the first insulation protection frame to be adjusted in real time. Combined with historical data and experience, determine a reasonable target adjustment temperature range. The range must not only ensure the normal operation of the electrical equipment, but also take into account the adjustment capability and efficiency of the temperature control equipment.

[0032] Step S422, obtaining the target adjustment temperature range of the identified thermal insulation protection frame. Specifically, the target adjustment temperature range of the identified thermal insulation protection frame is obtained. The identified thermal insulation protection frame is a protection frame that is greatly affected by heat conduction. The determination of its temperature range needs to comprehensively consider the relationship with the first thermal insulation protection frame to be adjusted and the requirements of the electrical equipment it carries. The influence of heat conduction between the identified thermal insulation protection frame and the first thermal insulation protection frame to be adjusted is considered. If the heat conduction between the two protection frames is more significant, then the target adjustment temperature range of the identified thermal insulation protection frame may need to be adjusted accordingly according to the temperature range of the first thermal insulation protection frame to be adjusted. The characteristics and working requirements of the electrical equipment installed in the identified thermal insulation protection frame are analyzed. Different electrical equipment may have different sensitivities to temperature. Therefore, it is necessary to determine a suitable target adjustment temperature range according to the specific situation. Combined with actual temperature monitoring data and experience, the target adjustment temperature range of the identified thermal insulation protection frame is determined. The range should not only ensure the normal operation of the electrical equipment, but also be coordinated with the temperature range of the first thermal insulation protection frame to be adjusted to achieve synchronous temperature adjustment.

[0033] Step S423, based on the target adjustment temperature range of the first insulation protection frame to be adjusted and the target adjustment temperature range of the identification insulation protection frame, generate constraint conditions, and constrain the temperature synchronization adjustment module with the constraint conditions. Specifically, based on the target adjustment temperature range of the first insulation protection frame to be adjusted and the identification insulation protection frame, generate constraint conditions to ensure that the temperature synchronization adjustment module can be adjusted within a reasonable range, and determine an upper limit temperature and a lower limit temperature based on the target adjustment temperature range of the first insulation protection frame to be adjusted. For example, if the target adjustment temperature range of the first insulation protection frame to be adjusted is [20°C, 30°C], then the upper limit temperature can be set to 30°C and the lower limit temperature can be set to 20°C. For the identification insulation protection frame, the corresponding upper limit temperature and lower limit temperature are also determined according to its target adjustment temperature range. Then, based on the heat conduction relationship between the two protection frames, establish constraint conditions. For example, it can be stipulated that the difference between the temperature of the identification insulation protection frame and the temperature of the first insulation protection frame to be adjusted cannot exceed a certain range. The generated constraint conditions are applied to the temperature synchronization adjustment module. When the temperature synchronization adjustment module is adjusting the temperature, these constraints must be met to ensure that the temperatures of the two protection frames are within the target adjustment temperature range. If the adjustment scheme calculated by the temperature synchronization adjustment module exceeds the constraints, it is necessary to readjust the parameters or use other optimization methods until the constraints are met to ensure that the temperatures of the first insulation protection frame to be adjusted and the identification insulation protection frame can be adjusted within a reasonable range, so as to achieve the goal of temperature synchronization adjustment and improve the reliability and stability of the electrical equipment in the power distribution cabinet.
