Description

Technical Field

[0001] The present invention belongs to the technical field of performance testing, and in particular relates to a method, device and medium for determining performance failure of a component. Background Art

[0002] The anti-seismic structure of the shutdown circuit breaker panel is the technical difficulty of the equipment. The rigidity and strength of the cabinet structure are the decisive factors for whether the shutdown circuit breaker, time relay, intermediate relay and other devices can perform their safety functions under vibration conditions. Once the cabinet structure design of the shutdown circuit breaker is unreasonable, the cabinet will be deformed due to insufficient rigidity or strength, and even cause damage to the components inside the cabinet. Therefore, it is particularly important to test the mechanical strength and internal components of the shutdown circuit breaker panel.

[0003] Based on the above background, the existing method for determining the performance failure of components in the shutdown circuit breaker panel adopts a unified determination method, that is, after the shutdown circuit breaker panel is in a vibration condition, the components inside the shutdown circuit breaker panel are manually inspected to see if they are normal. This detection method can determine whether the performance of the components has failed to a certain extent. However, due to the different internal and external structures of the shutdown circuit breaker panel and the different types of its components, this determination method is inefficient and inaccurate, and is no longer applicable to the performance failure determination of components in the shutdown circuit breaker panel.

[0004] To this end, we propose performance failure determination methods, equipment and media for components. Summary of the invention

[0005] In view of the deficiencies in the prior art, the present invention aims to provide a method, device and medium for determining performance failure of components.

[0006] The technical problems to be solved by the present invention are:

[0007] How to achieve comprehensive judgment on the performance of components in the shutdown circuit breaker panel based on multi-source data.

[0008] In order to achieve the above object, the present invention adopts the following technical solutions:

[0009] In the first aspect, a method for determining performance failure of a component, the method steps specifically include:

[0010] Step S101, measuring the cabinet specifications of the shutdown circuit breaker panel;

[0011] Step S102, measuring the protection level of the shutdown circuit breaker panel without components installed;

[0012] Step S103, completing the installation of various components in the shutdown circuit breaker panel, and analyzing the installation status of the components in the shutdown circuit breaker panel;

[0013] Step S104, setting corresponding test parameters of the shutdown circuit breaker panel according to the protection level and the structural complexity coefficient; the test parameters include mechanical collision test parameters and seismic test parameters;

[0014] Step S105, performing a mechanical collision test and a seismic test on the shutdown circuit breaker panel according to the test parameters;

[0015] Step S106, performing an environmental operation test on the shutdown circuit breaker panel;

[0016] Step S107, determining the performance failure risk of components in the shutdown circuit breaker panel according to the test results;

[0017] Step S108, executing corresponding structural reinforcement measures according to the risk level.

[0018] Furthermore, the protection level determination process of the shutdown circuit breaker panel in step S102 is specifically as follows:

[0019] Obtain the cabinet length BC, cabinet width BK, and cabinet height BG of the shutdown circuit breaker panel, and calculate the cabinet space volume BV of the shutdown circuit breaker panel according to the formula. The specific formula is as follows:

[0020] BV = BC × BK × BG;

[0021] Obtain the compartment length GCi, compartment width GKi and compartment height GGi of each functional compartment in the shutdown circuit breaker panel, where i is the functional compartment number, i is a positive integer, the upper limit of i is n, and the value of n is equal to the number of functional compartments in the shutdown circuit breaker panel;

[0022] Then the functional space volume GV of the shutdown circuit breaker panel is calculated according to the formula, which is as follows:

[0023] ; Among them, the value of the functional space volume is always smaller than the value of the cabinet space volume;

[0024] Finally, the buffer reserve coefficient HY of the shutdown circuit breaker panel is calculated according to the formula, and the specific formula is as follows:

[0025] HY = (BV-GV) / BV;

[0026] Compare the buffer reserve factor of the shutdown circuit breaker panel with the buffer reserve threshold;

[0027] If the buffer reserve coefficient is less than or equal to the first buffer reserve threshold, it is determined that the protection level of the shutdown circuit breaker panel is the third protection level;

[0028] If the buffer reserve coefficient is greater than the first buffer reserve threshold and less than or equal to the second buffer reserve threshold, it is determined that the protection level of the shutdown circuit breaker panel is the second protection level;

[0029] If the buffer reserve coefficient is greater than the second buffer reserve threshold, it is determined that the protection level of the shutdown circuit breaker panel is the first protection level;

[0030] Among them, the buffer reservation threshold is pre-stored in the memory, the values ​​of the first buffer reservation threshold and the second buffer reservation threshold are both greater than zero, the first buffer reservation threshold is less than the second buffer reservation threshold, the protection requirement of the first protection level is lower than the protection requirement of the second protection level, and the protection requirement of the second protection level is lower than the protection requirement of the third protection level.

[0031] Furthermore, the analysis process of the component installation status in step S103 is specifically as follows:

[0032] Counting the component configuration data of each functional compartment, the component configuration data includes the number of energized components DYi, the number of non-energized components FYi and the critical spacing distance LMi of each functional compartment in the shutdown circuit breaker panel, wherein the spacing distance between adjacent components in the functional compartment is measured by a measuring device, and the minimum value of the spacing distance obtained by traversal comparison is recorded as the critical spacing distance;

[0035] Among them, s1 is the structural complexity weight of the energized components, s2 is the structural complexity weight of the non-energized components, the values ​​of s1 and s2 are both greater than zero, s1+s2=1, and LB is the standard spacing distance.

[0036] Furthermore, the corresponding relationship between the mechanical collision test parameters and the protection level in step S104 is as follows:

[0037] If the protection level of the shutdown circuit breaker panel is the first protection level, the corresponding mechanical collision test parameters are the first collision intensity and the third collision contact area;

[0038] If the protection level of the shutdown circuit breaker panel is the second protection level, the corresponding mechanical collision test parameters are the second collision intensity and the second collision contact area respectively;

[0039] If the protection level of the shutdown circuit breaker panel is the third protection level, the corresponding mechanical collision test parameters are the third collision intensity and the first collision contact area;

[0040] The mechanical collision force of the first collision intensity is lower than the mechanical collision force of the second collision intensity, the mechanical collision force of the second collision intensity is lower than the mechanical collision force of the third collision intensity, the value of the first collision contact area is lower than the value of the second collision contact area, and the value of the second collision contact area is lower than the value of the third collision contact area;

[0041] The corresponding relationship between the seismic test parameters and the structural complexity coefficient in step S104 is as follows:

[0042] The seismic test parameters are specifically the forced vibration interval of the components. The forced vibration interval is a symmetrical interval with a middle value of zero. The interval length corresponding to the forced vibration interval is inversely proportional to the structural complexity coefficient of the shutdown circuit breaker panel.

[0043] Furthermore, the testing process of the mechanical collision test in step S105 is specifically as follows;

[0044] Obtain and select a corresponding collision hammer head according to the collision contact area corresponding to the shutdown circuit breaker panel;

[0045] Obtain and set the collision speed of the collision hammer according to the collision strength corresponding to the shutdown circuit breaker panel;

[0046] Perform collision tests on various test surfaces of the shutdown circuit breaker panel, including the upper test surface, the lower test surface, the left test surface, the right test surface, the front test surface and the rear test surface;

[0047] The collision deformation value of the shell of the shutdown circuit breaker panel before and after the collision is obtained by a measuring device, and the collision deformation value is compared with the standard deformation range;

[0048] If the collision deformation value belongs to the first standard deformation interval, the collision test result of the shutdown circuit breaker panel is determined to be qualified;

[0049] If the collision deformation value belongs to the second standard deformation range, the collision test result of the shutdown circuit breaker panel is determined to be unqualified;

[0050] Among them, the values ​​of the first standard deformation interval and the second standard deformation interval are both greater than zero, and the values ​​of the first standard deformation interval are both smaller than the values ​​of the second standard deformation interval;

[0051] The test process of the seismic test in step S105 is specifically as follows:

[0052] The shutdown circuit breaker panel is fixed on the vibration test bench. After the vibration test bench is turned on, it vibrates periodically at a fixed vibration frequency. The periodic vibration includes up-and-down vibration and left-and-right vibration.

[0053] Obtain the amplitude of components in the functional compartment of the shutdown circuit breaker panel through the measuring device;

[0054] Compare the forced vibration amplitude of each component in the functional compartment with the corresponding forced vibration range;

[0055] If the forced amplitude of any component does not belong to the corresponding forced vibration range, the seismic test result of the shutdown circuit breaker panel is judged to be unqualified;

[0056] If the forced amplitudes of the components all belong to the corresponding forced vibration range, the seismic test results of the shutdown circuit breaker panel are judged to be qualified.

[0057] Furthermore, the test process of the environment operation test in step S106 is specifically as follows:

[0058] The shutdown circuit breaker panel is placed in the center of the test site, and the test site is equipped with temperature control equipment to simulate high temperature environment;

[0059] After starting the temperature control equipment, the external temperature of the shutdown circuit breaker panel and the compartment temperature of each functional compartment are obtained through a thermometer, the temperature of the shell of the shutdown circuit breaker panel is obtained through an infrared thermometer and recorded as the external temperature, and the temperature inside the functional compartment is obtained through a thermometer set in each functional compartment of the shutdown circuit breaker panel and recorded as the compartment temperature;

[0060] Gradually increase the output power of the temperature control equipment, and continuously record the external temperature WT of the shutdown circuit breaker panel and the compartment temperature GTi of each functional compartment until the external temperature reaches the test critical temperature, then stop recording;

[0061] The thermal conduction barrier value RZ of the shutdown circuit breaker panel is calculated according to the formula, which is as follows:

[0062] ;

[0063] Compare the thermal conduction barrier value of the shutdown circuit breaker panel during the test with the thermal conduction barrier critical value;

[0064] If the heat conduction barrier value is greater than or equal to the heat conduction barrier critical value, the environmental operation test result of the shutdown circuit breaker panel is determined to be qualified;

[0065] If the thermal conduction barrier value is less than the thermal conduction barrier critical value, the environmental operation test result of the shutdown circuit breaker panel is determined to be unqualified.

[0066] Furthermore, the determination process of the performance failure risk in step S107 is specifically as follows:

[0067] Obtain the collision test results, seismic test results and environmental operation test results of the shutdown circuit breaker panel;

[0068] If two or more of the test results are unqualified, the failure risk level of the shutdown circuit breaker panel is determined to be the third risk level;

[0069] If one of the test results is unqualified, the failure risk level of the shutdown circuit breaker panel is determined to be the second risk level;

[0070] If any of the test results is qualified, the failure risk level of the shutdown circuit breaker panel is determined to be the first risk level;

[0071] Among them, the performance failure risk of the first risk level is lower than the performance failure risk of the second risk level, and the performance failure risk of the second risk level is lower than the performance failure risk of the third risk level.

[0072] Furthermore, the correspondence between the structural reinforcement measures and the risk levels in step S108 is as follows:

[0073] If the failure risk level of the shutdown circuit breaker panel is determined to be the first risk level, no structural reinforcement measures are required;

[0074] If the failure risk level of the shutdown circuit breaker panel is determined to be the second risk level, the load-bearing parts and connection parts of the shutdown circuit breaker panel are reinforced by welding with reinforcing ribs;

[0075] If the failure risk level of the shutdown circuit breaker panel is determined to be the third risk level, the load-bearing parts and connection parts of the shutdown circuit breaker panel are reinforced by welding reinforcing ribs, and components with seismic performance are selected to the maximum extent possible, and the layout of components is optimized during the installation process.

[0080] In summary, due to the adoption of the above technical solution, the beneficial effects of the present invention are:

[0081] On the one hand, the present invention measures the cabinet specifications of the shutdown circuit breaker panel, determines the protection level of the shutdown circuit breaker panel without components installed based on the measured data, then completes the installation of various components in the shutdown circuit breaker panel, and analyzes the installation status of the components of the shutdown circuit breaker panel to obtain the corresponding structural complexity coefficient of the shutdown circuit breaker panel, sets the corresponding test parameters of the shutdown circuit breaker panel according to the protection level and the structural complexity coefficient, and performs mechanical collision test and seismic test on the shutdown circuit breaker panel according to the test parameters. On the other hand, the shutdown circuit breaker panel is tested for environmental operation, and the performance failure risk of the components in the shutdown circuit breaker panel is determined according to the three test results to obtain the corresponding risk level, and corresponding structural reinforcement measures are implemented according to the risk level.

[0087] The technical solution of the present invention will be clearly and completely described below in conjunction with the embodiments. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0088] Embodiment 1:

[0089] See also Figure 1-3 As shown, the technical solution provided by the present invention is: a method for determining performance failure of a component, and the method steps specifically include:

[0090] Step S101, measuring the cabinet specifications of the shutdown circuit breaker panel;

[0091] In this embodiment, the basic frame of the shutdown circuit breaker panel is preferably a floor-standing self-supporting structure, the main frame is formed by welding and screw assembly, and the shutdown circuit breaker panel is fixed and installed by welding the bottom of the cabinet to the foundation channel steel;

[0092] The cabinet of the shutdown circuit breaker panel is divided into several functional areas by partitions. In the actual working process, taking the DC shutdown circuit breaker panel as an example, the cabinet of the DC shutdown circuit breaker panel is divided into four functional compartments by partitions. The functional compartments include busbar room, electrical room, cable room and instrument control room. The main busbar room is set at the top of the cabinet, the electrical room is set at the front of the cabinet, the cable room is set at the lower rear of the cabinet, and the instrument control room is set at the upper front of the cabinet. Each functional compartment is independently isolated accordingly;

[0093] In step S101, refer to Figure 2 and Figure 3 As shown, the cabinet specification data of the shutdown circuit breaker panel is obtained by a measuring device, and the cabinet specification data includes the cabinet length, cabinet width, cabinet height, and compartment length, compartment width, and compartment height of each functional compartment in the shutdown circuit breaker panel;

[0094] like Figure 3 As shown, the distance between the left and right shells of the shutdown circuit breaker panel is measured and recorded as the cabinet length. Similarly, the distance between the upper and lower shells of the shutdown circuit breaker panel is measured and recorded as the cabinet height. The distance between the front and rear shells of the shutdown circuit breaker panel is measured and recorded as the cabinet width.

[0095] The distance between the left and right inner walls of the functional compartment in the shutdown circuit breaker panel is also measured and recorded as the compartment length. Similarly, the distance between the upper and lower inner walls of the functional compartment in the shutdown circuit breaker panel is measured and recorded as the compartment height. The distance between the front and rear inner walls of the functional compartment in the shutdown circuit breaker panel is measured and recorded as the compartment width. In this embodiment, the inner wall of the functional compartment includes a partition provided in the shutdown circuit breaker panel and a cabinet of the shutdown circuit breaker panel.

[0096] Step S102, measuring the protection level of the shutdown circuit breaker panel without components installed;

[0097] In step S102, the protection level determination process of the shutdown circuit breaker panel is as follows:

[0098] Obtain the cabinet length BC, cabinet width BK, and cabinet height BG of the shutdown circuit breaker panel, and calculate the cabinet space volume BV of the shutdown circuit breaker panel according to the formula. The specific formula is as follows:

[0099] BV = BC × BK × BG;

[0100] Obtain the compartment length GCi, compartment width GKi and compartment height GGi of each functional compartment in the shutdown circuit breaker panel, where i is the functional compartment number, i is a positive integer, the upper limit of i is n, and the value of n is equal to the number of functional compartments in the shutdown circuit breaker panel. Calculate the functional space volume GV of the shutdown circuit breaker panel according to the formula, which is as follows:

[0101] ;

[0102] Among them, the value of the functional space volume is always smaller than the value of the cabinet space volume. In the actual working process, a certain amount of buffer space is reserved between the shell of the shutdown circuit breaker panel and each functional compartment. When the cabinet of the shutdown circuit breaker panel is deformed due to mechanical collision and vibration, the buffer space will reduce the impact on each functional compartment.

[0103] The buffer reserve coefficient HY of the shutdown circuit breaker panel is calculated according to the formula, and the formula is as follows:

[0104] HY = (BV-GV) / BV;

[0105] It can be understood that the buffer reserve coefficient reflects the percentage of the space in the shutdown circuit breaker panel that plays a buffering role. The larger the value of the buffer reserve coefficient, the higher the degree of deformation that the shell of the shutdown circuit breaker panel can withstand.

[0106] Compare the buffer reserve factor of the shutdown circuit breaker panel with the buffer reserve threshold;

[0107] If the buffer reserve coefficient is less than or equal to the first buffer reserve threshold, it is determined that the protection level of the shutdown circuit breaker panel is the third protection level;

[0108] If the buffer reserve coefficient is greater than the first buffer reserve threshold and less than or equal to the second buffer reserve threshold, it is determined that the protection level of the shutdown circuit breaker panel is the second protection level;

[0109] If the buffer reserve coefficient is greater than the second buffer reserve threshold, it is determined that the protection level of the shutdown circuit breaker panel is the first protection level;

[0110] The buffer reservation threshold is pre-stored in the memory, the values ​​of the first buffer reservation threshold and the second buffer reservation threshold are both greater than zero, the first buffer reservation threshold is less than the second buffer reservation threshold, the protection requirement of the first protection level is lower than the protection requirement of the second protection level, and the protection requirement of the second protection level is lower than the protection requirement of the third protection level;

[0111] Step S103, completing the installation of various components in the shutdown circuit breaker panel, and analyzing the installation status of the components in the shutdown circuit breaker panel;

[0112] In this embodiment, the components include energized components and non-energized components;

[0113] In actual operation, the components installed in the shutdown circuit breaker panel include circuit breakers, intermediate relays, DC contactors, time relays, wiring terminals, temperature and humidity controllers, fuses and other energized components, as well as terminal baffles, busbar clamps, busbar wiring clamps, cross-connectors and other non-energized components;

[0114] In step S103, the analysis process of component installation status is as follows:

[0115] Counting the component configuration data of each functional compartment, the component configuration data includes the number of energized components DYi, the number of non-energized components FYi and the critical spacing distance LMi of each functional compartment in the shutdown circuit breaker panel, wherein the spacing distance between adjacent components in the functional compartment is measured by a measuring device, and the minimum value of the spacing distance obtained by traversal comparison is recorded as the critical spacing distance;

[0116] The structural complexity coefficient JGi of each functional compartment in the shutdown circuit breaker panel is calculated according to the formula. The specific formula is as follows:

[0117] ;

[0118] Among them, s1 is the structural complexity weight of the energized components, s2 is the structural complexity weight of the non-energized components, the values ​​of s1 and s2 are both greater than zero, s1+s2=1, and LB is the standard spacing distance. It can be understood that when the critical spacing distance is greater than the standard spacing distance, it is not easy for components to collide with each other, and when the critical spacing distance is less than the standard spacing distance, it is easy for components to collide with each other;

[0119] Step S104, setting the test parameters corresponding to the shutdown circuit breaker panel according to the protection level and the structural complexity coefficient;

[0120] The test parameters include mechanical collision test parameters and seismic test parameters;

[0121] In step S104, the correspondence between the mechanical collision test parameters and the protection level is as follows:

[0122] If the protection level of the shutdown circuit breaker panel is the first protection level, the corresponding mechanical collision test parameters are the first collision intensity and the third collision contact area;

[0123] If the protection level of the shutdown circuit breaker panel is the second protection level, the corresponding mechanical collision test parameters are the second collision intensity and the second collision contact area respectively;

[0124] If the protection level of the shutdown circuit breaker panel is the third protection level, the corresponding mechanical collision test parameters are the third collision intensity and the first collision contact area;

[0125] The mechanical collision force of the first collision intensity is lower than the mechanical collision force of the second collision intensity, the mechanical collision force of the second collision intensity is lower than the mechanical collision force of the third collision intensity, the value of the first collision contact area is lower than the value of the second collision contact area, and the value of the second collision contact area is lower than the value of the third collision contact area;

[0126] In step S104, the corresponding relationship between the seismic test parameters and the structural complexity coefficient is as follows:

[0127] The seismic test parameters are specifically the forced vibration interval of the components. The forced vibration interval is a symmetrical interval with a middle value of zero. The interval length of the corresponding forced vibration interval is inversely proportional to the structural complexity coefficient of the shutdown circuit breaker panel. For example, when the structural complexity coefficient of the shutdown circuit breaker panel is 20, the corresponding forced vibration interval is (-10mm, 10mm). When the structural complexity coefficient of the shutdown circuit breaker panel is 30, the corresponding forced vibration interval is (-7.5mm, 7.5mm).

[0128] Step S105, performing a mechanical collision test and a seismic test on the shutdown circuit breaker panel according to the test parameters;

[0129] In step S105, the testing process of the mechanical collision test is specifically as follows;

[0130] Obtain and select a corresponding collision hammer head according to the collision contact area corresponding to the shutdown circuit breaker panel. In the actual test process, the collision hammer head performs a collision test at an angle perpendicular to the shell of the shutdown circuit breaker panel. During the collision process, the contact area between the collision hammer head and the shell of the shutdown circuit breaker panel is equal to the corresponding collision contact area.

[0131] Obtain and set the collision speed of the collision hammer according to the collision strength corresponding to the shutdown circuit breaker panel. It should be specifically noted that, in this embodiment, the collision hammer selected has the same properties except for the collision contact area and the collision speed, for example, the hammer material, the hammer mass, the distance between the hammer and the shutdown circuit breaker panel housing, etc.;

[0132] It can be understood that according to the momentum formula: p=mv, when the mass of the hammer is the same, the faster the collision speed of the impact hammer, the higher the collision intensity;

[0133] Perform collision tests on various test surfaces of the shutdown circuit breaker panel, including the upper test surface, the lower test surface, the left test surface, the right test surface, the front test surface and the rear test surface;

[0134] The collision deformation value of the shell of the shutdown circuit breaker panel before and after the collision is obtained by a measuring device. In this embodiment, the difference between the deepest point of the shell of the shutdown circuit breaker panel after the collision and the shell is measured by a vernier caliper and recorded as the collision deformation value;

[0135] Compare the collision deformation value with the standard deformation range;

[0136] If the collision deformation value belongs to the first standard deformation interval, the collision test result of the shutdown circuit breaker panel is determined to be qualified;

[0137] If the collision deformation value belongs to the second standard deformation range, the collision test result of the shutdown circuit breaker panel is determined to be unqualified;

[0138] Among them, the values ​​of the first standard deformation interval and the second standard deformation interval are both greater than zero, and the values ​​of the first standard deformation interval are all less than the values ​​of the second standard deformation interval. It can be understood that when the standard deformation interval belongs to the second standard deformation interval, the collision deformation of the outer shell of the shutdown circuit breaker panel will be transmitted to the functional compartment, thereby causing damage to components;

[0139] The test process of the seismic test is as follows:

[0140] The shutdown circuit breaker panel is fixed on the vibration test bench. After the vibration test bench is turned on, it vibrates periodically at a fixed vibration frequency. The periodic vibration includes up and down vibration and left and right vibration. In this embodiment, the duration of the periodic vibration remains consistent.

[0141] The amplitude of the components in the functional compartments of the shutdown circuit breaker panel is obtained by a measuring device. In this embodiment, the amplitude of the forced vibration of the components is obtained by an amplitude meter arranged in each functional compartment and recorded as the forced amplitude of the components;

[0142] Compare the forced vibration amplitude of each component in the functional compartment with the corresponding forced vibration range;

[0143] If the forced amplitude of any component does not belong to the corresponding forced vibration range, the seismic test result of the shutdown circuit breaker panel is judged to be unqualified;

[0144] If the forced vibration amplitudes of the components all belong to the corresponding forced vibration range, the seismic test results of the shutdown circuit breaker panel are judged to be qualified;

[0145] Step S106, performing an environmental operation test on the shutdown circuit breaker panel;

[0146] In step S106, the test process of the environment operation test is as follows:

[0147] The shutdown circuit breaker panel is placed in the center of the test site. The test site is equipped with temperature control equipment for simulating high temperature environment. In the actual working process, the temperature control equipment includes but is not limited to heating equipment such as spotlights and quartz lamps;

[0148] After starting the temperature control equipment, the external temperature of the shutdown circuit breaker panel and the compartment temperature of each functional compartment are obtained through a thermometer, the temperature of the shell of the shutdown circuit breaker panel is obtained through an infrared thermometer and recorded as the external temperature, and the temperature inside the functional compartment is obtained through a thermometer set in each functional compartment of the shutdown circuit breaker panel and recorded as the compartment temperature;

[0149] Gradually increase the output power of the temperature control equipment, and continuously record the external temperature WT of the shutdown circuit breaker panel and the compartment temperature GTi of each functional compartment until the external temperature reaches the test critical temperature, then stop recording;

[0150] The thermal conduction barrier value RZ of the shutdown circuit breaker panel is calculated according to the formula, which is as follows:

[0151] ;

[0152] It can be understood that the heat conduction barrier value reflects the barrier effect of the shutdown circuit breaker panel shell on heat conduction. The larger the value of the heat conduction barrier value, the better the barrier effect of heat conduction.

[0153] Compare the thermal conduction barrier value of the shutdown circuit breaker panel during the test with the thermal conduction barrier critical value;

[0154] If the heat conduction barrier value is greater than or equal to the heat conduction barrier critical value, the environmental operation test result of the shutdown circuit breaker panel is determined to be qualified;

[0155] If the heat conduction barrier value is less than the heat conduction barrier critical value, the environmental operation test result of the shutdown circuit breaker panel is judged to be unqualified;

[0156] Wherein, the heat conduction barrier critical value is pre-stored in the memory, and when the conduction barrier value is less than the heat conduction barrier critical value, the shutdown circuit breaker panel loses its original heat insulation property;

[0157] Step S107, determining the performance failure risk of components in the shutdown circuit breaker panel according to the test results;

[0158] In step S107, the component performance determination process is as follows:

[0159] Obtain the collision test results, seismic test results and environmental operation test results of the shutdown circuit breaker panel;

[0160] If two or more of the test results are unqualified, the failure risk level of the shutdown circuit breaker panel is determined to be the third risk level;

[0161] If one of the test results is unqualified, the failure risk level of the shutdown circuit breaker panel is determined to be the second risk level;

[0162] If any of the test results is qualified, the failure risk level of the shutdown circuit breaker panel is determined to be the first risk level;

[0163] Among them, the performance failure risk of the first risk level is lower than the performance failure risk of the second risk level, and the performance failure risk of the second risk level is lower than the performance failure risk of the third risk level;

[0164] Step S108, executing corresponding structural reinforcement measures according to the risk level;

[0165] In step S108, the correspondence between the structural reinforcement measures and the risk levels is as follows:

[0166] If the failure risk level of the shutdown circuit breaker panel is determined to be the first risk level, no structural reinforcement measures are required;

[0167] If the failure risk level of the shutdown circuit breaker panel is determined to be the second risk level, the load-bearing parts and connection parts of the shutdown circuit breaker panel are reinforced by welding with reinforcing ribs;
