Description

Technical Field

[0001] This invention relates to the field of electrical switch technology, and in particular to a control method and system for an electric spring operating mechanism with a clutch. Background Technology

[0002] An electrical switch is an electrical component that can connect, disconnect, or switch circuits. Its core function is to control the transmission path and on / off state of electrical energy, ensuring the safety, stability, and controllability of circuit operation. It is widely used in power systems, industrial automation, building power distribution, new energy, and daily life.

[0003] The spring-energy-storage electric operating mechanism is an electrical switch used for high-voltage isolation, grounding, and load control. It includes a motor, a worm gear for transmission, an energy-storage spring, a driven pin mounted on the end of the energy-storage spring, an output shaft, a driven crank arm, an eccentric wheel, and a micro switch. The driven crank arm and eccentric wheel are both mounted on the output shaft. The driven pin drives the driven crank arm to rotate, and the eccentric wheel controls the micro switch to open. When the spring-energy-storage electric operating mechanism is in the open position, pressing the close button energizes the motor, causing the worm gear to rotate. The worm gear drives the driven pin to rotate clockwise, compressing the energy-storage spring. At the moment the energy-storage spring passes its midpoint, it rapidly releases energy. The driven pin then drives the driven crank arm, causing the output shaft to rotate and complete the closing action. Simultaneously, the eccentric wheel on the output shaft opens the normally closed contact of the micro switch, stopping the motor. When the circuit is closed, pressing the trip button controls the motor to be energized, which drives the driven shaft pin to rotate counterclockwise and compresses the energy storage spring. When the energy storage spring passes the center, the driven shaft pin pushes the driven crank arm to drive the output shaft to rotate and complete the tripping action.

[0004] When a spring-powered electric operating mechanism is used for a long time, the energy storage spring is prone to fatigue and deformation due to prolonged stress. This can lead to a slower closing speed or even failure to complete the closing action, which in turn can cause circuit failures. Summary of the Invention

[0005] To reduce the probability of circuit failures, this invention provides a control method and system for an electric spring operating mechanism with a clutch.

[0006] In a first aspect, the present invention provides a control method for an electric spring operating mechanism with a clutch, employing the following technical solution:

[0007] A control method for an electric spring-operated mechanism with a clutch, comprising:

[0008] Collect switch opening and closing requirements, transmission specifications, spring specifications, and stress test values;

[0009] Determine the energy storage reference value and stress reference value according to the spring specifications;

[0010] Calculate the difference between the stress test value and the stress reference value and use it as the stress deviation value;

[0011] Collect historical usage parameters of the switch;

[0012] Determine the stress reference deviation value based on the historical usage parameters of the switch, and determine whether the stress deviation value is less than the stress reference deviation value.

[0013] If so, then determine the stress deviation adjustment value based on the stress deviation value, and use the stress deviation adjustment value as the stress adjustment value;

[0014] If not, then collect the switch environmental parameters, determine the environmental impact value based on the switch environmental parameters, determine the environmental adjustment value by combining the environmental impact value and the stress deviation value, and use the environmental adjustment value as the stress adjustment value;

[0015] Calculate the product between the energy storage baseline value and the stress adjustment value and use it as the energy storage change value; determine the energy storage time based on the switching requirements.

[0016] The motor rotation power is determined by combining the energy storage time, energy storage change value, and transmission specifications, and the motor rotation parameters are output.

[0017] By adopting the above technical solution, the requirements for switch opening and closing, transmission specifications, spring specifications, and stress detection values ​​are collected. First, the energy storage reference value and stress reference value are determined based on the spring specifications. By distinguishing between two cases where the stress deviation value is less than the stress reference deviation value, the stress deviation adjustment value or the environmental adjustment value combined with environmental parameters is used as the stress adjustment value, and then the energy storage change value is calculated. Finally, the motor rotation power is determined and the parameters are output by combining the energy storage time and transmission specifications. This achieves precise matching between the motor rotation parameters and the real-time energy storage status of the spring, improves the operational stability and reliability of the electric spring operating mechanism with clutch, and reduces the probability of circuit failure.

[0018] Optional methods for determining environmental impact values ​​include:

[0019] Based on the switch environment parameters, retrieve the ambient temperature, ambient humidity, and ambient dust parameters;

[0020] The temperature effect value is determined by combining the ambient temperature value and the spring specifications;

[0021] Based on environmental dust parameters, retrieve the type of dust and the amount of dust per type;

[0022] The corrosion impact value and the dust impact value are determined by combining the ambient humidity value, dust type and the amount of single dust type;

[0023] The comprehensive impact value is determined based on the temperature impact value, corrosion impact value, and dust impact value, and is used as the environmental impact value.

[0024] By adopting the above technical solution, the influence values ​​of temperature, corrosion and dust are determined by retrieving the ambient temperature, humidity and dust parameters, and finally the comprehensive influence value is obtained as the environmental influence value. This reduces the abnormal spring stress caused by environmental factors such as temperature, humidity and dust, and ensures the accuracy of the stress adjustment value.

[0025] Optional methods for determining corrosion impact values ​​include:

[0026] Select a dust type that is consistent with the preset corrosion type and use it as the consistent type. Also, use the amount of dust of the single type corresponding to the consistent type as the consistent dust amount.

[0027] Determine the humidity unit value and the number of consistent values ​​based on the consistent category;

[0028] Determine whether there is only one identical value;

[0029] If so, the corrosion coefficient value is determined by combining the ambient humidity value and the humidity unit value;

[0030] Calculate the product between the consistent dust amount and the corrosion coefficient value and use it as the single-type influence value, and use the single-type influence value as the corrosion influence value;

[0031] If not, then combine the consistent dust amount and humidity unit values ​​to determine the multi-category coefficient values;

[0032] Calculate the product between the ambient humidity value and the multi-type coefficient value and use it as the multi-type influence value, and use the multi-type influence value as the corrosion influence value.

[0033] By adopting the above technical solution, the accuracy of corrosion impact value calculation is improved by screening dust of the same type and distinguishing the same value as single or multiple, and calculating the single-type impact value or the multi-type impact value as corrosion impact value. This ensures the accuracy of subsequent environmental adjustment value and stress adjustment value.

[0034] Optional methods for determining the values ​​of multiple coefficients include:

[0035] The duration value is retrieved based on the consistent dust level;

[0036] Sort the values ​​by duration from smallest to largest, and then obtain the time sorting value based on the sorting result;

[0037] Based on the consistent dust amount, the dust is sorted from smallest to largest, and the content ranking value is obtained according to the ranking result;

[0038] Calculate the sum between the time-ranked value and the content-ranked value, and use it as the comprehensive ranking value;

[0039] The ranking percentage coefficient is determined based on the comprehensive ranking value;

[0040] The humidity unit values ​​are weighted based on the sorting proportion coefficient to determine the coefficient values ​​for various categories.

[0041] By adopting the above technical solution, the duration and content of consistent dust are sorted, a comprehensive sorting value is calculated and a sorting ratio coefficient is determined, and then the humidity unit value is weighted to obtain various coefficient values, which provides reliable support for the accurate calculation of environmental impact values.

[0042] Optional methods for determining dust impact values ​​include:

[0043] Dust types other than the same type are considered as the remaining types, and the amount of dust of each of the remaining types is considered as the remaining dust amount.

[0044] Retrieve the remaining humidity and viscosity values ​​and the viscosity reference humidity range based on the remaining types;

[0045] Determine the humidity reference value by combining the ambient humidity value with the viscosity reference humidity range;

[0046] Determine the viscosity ratio by combining the humidity reference value and the viscosity value at residual humidity;

[0047] Calculate the product between the viscosity ratio and the amount of remaining dust, and use it as the dust adhesion amount;

[0048] The adhesion effect value is determined by combining the dust adhesion amount and the spring specifications, and the adhesion effect value is used as the dust effect value.

[0049] By adopting the above technical solution, the remaining types of dust are classified, and the humidity reference value is determined by combining the remaining humidity viscosity value and the viscosity reference humidity range. Then, the dust adhesion amount and adhesion influence value are calculated as the dust influence value. This realizes the differentiation and quantification of the influence of corrosive dust and non-corrosive dust, and takes into account the increase in spring extension resistance and stress anomaly caused by dust adhesion. This makes the assessment of the influence of dust factors on spring stress more comprehensive and improves the adaptability of stress adjustment value.

[0050] Optionally, after using the environmental adjustment value as the stress adjustment value, the following may also be included:

[0051] Collect spring displacement values;

[0052] The displacement change value is determined based on the spring displacement value;

[0053] Determine the estimated deformation based on the displacement change value;

[0054] Determine the standard deformation reference value based on the spring specifications;

[0055] When the estimated deformation value is greater than the standard deformation reference value, the difference between the estimated deformation value and the standard deformation reference value is calculated and used as the deformation deviation value.

[0056] The deformation adjustment value is determined based on the deformation deviation value, and then added to the stress adjustment value for updating and replacement.

[0057] By adopting the above technical solution, the displacement change value and deformation estimate are determined by collecting the spring displacement value. The deformation reference value is compared with the standard value. After the deformation estimate exceeds the limit, the deformation deviation value is calculated and the deformation adjustment value is determined to update the stress adjustment value. This allows for timely detection of stress anomalies caused by spring deformation, avoids energy storage imbalance caused by spring plastic deformation, and further ensures the accuracy of the stress adjustment value.

[0058] Optional methods for determining deformation estimates include:

[0059] Retrieve the change time value and the previous change value based on the displacement change value;

[0060] Calculate the quotient between the displacement change value and the change time value, and use it as the change rate value;

[0061] Determine the rate estimate based on the rate of change value;

[0062] The change estimate is determined by combining the rate estimate with the previous change value;

[0063] Retrieve the previous displacement value based on the spring displacement value;

[0064] The deformation estimate is determined by combining the previous displacement value with the change estimate.

[0065] By adopting the above technical solution, the rate of change is calculated by retrieving the change time value of the displacement change value and the previous change value. The change estimate is determined by combining the rate estimate with historical data, and finally the deformation estimate is obtained. This enables a forward-looking prediction of the spring deformation trend and provides data support for the timely determination of the subsequent deformation adjustment value.

[0066] Optional methods for determining the deformation adjustment value include:

[0067] Determine the spacing deviation value by combining the spring specifications and deformation deviation value;

[0068] Determine the adhesion tolerance and spacing deviation adjustment value based on the spacing deviation value;

[0069] Determine whether the amount of dust adhering is less than the allowable amount;

[0070] If so, the spacing deviation adjustment value will be used as the deformation adjustment value;

[0071] If not, calculate the difference between the dust adhesion amount and the adhesion tolerance and use it as the adhesion deviation value;

[0072] Determine the influence value of adhesion deviation based on the adhesion deviation value;

[0073] Calculate the product between the adhesion deviation influence value and the spacing deviation adjustment value, and use it as the deformation adjustment value.

[0074] By adopting the above technical solution, the spacing deviation value is determined by combining the spring specifications and the deformation deviation value. It distinguishes whether the amount of dust adhesion is less than the adhesion tolerance. The spacing deviation adjustment value or the product value of the adhesion deviation influence value is used as the deformation adjustment value, which realizes the linkage control between deformation adjustment and dust adhesion influence. This makes the deformation adjustment value more consistent with the actual deformation cause of the spring and improves the final calibration accuracy of the stress adjustment value.

[0075] Secondly, the present invention provides a control system for an electric spring operating mechanism with a clutch, which adopts the following technical solution:

[0076] A control system for an electric spring-operated mechanism with a clutch, comprising:

[0077] The data acquisition module is used to collect switch opening and closing requirements, transmission specifications, spring specifications, stress detection values, historical switch usage parameters, switch environmental parameters, and spring displacement values.

[0078] The memory stores a program for implementing a control method for an electric spring-operated mechanism with a clutch as described in any one of the first aspects;

[0079] The processor loads and executes programs stored in memory.

[0080] In summary, the present invention has at least one of the following beneficial technical effects:

[0081] 1. By collecting data on switch opening and closing requirements, transmission specifications, spring specifications, and stress detection values, the energy storage reference value and stress reference value are first determined based on the spring specifications. By distinguishing between two cases where the stress deviation value is less than the stress reference deviation value, the stress deviation adjustment value or the environmental adjustment value combined with environmental parameters is used as the stress adjustment value, and then the energy storage change value is calculated. Finally, the motor rotation power is determined and the parameters are output by combining the energy storage time and transmission specifications. This achieves precise matching between the motor rotation parameters and the real-time energy storage status of the spring, improves the operational stability and reliability of the electric spring operating mechanism with clutch, and reduces the probability of circuit failure.

[0082] 2. By retrieving ambient temperature, humidity, and dust parameters, the influence values ​​of temperature, corrosion, and dust are determined respectively, and the final comprehensive influence value is used as the environmental influence value. This reduces the abnormal spring stress caused by environmental factors such as temperature, humidity, and dust, and ensures the accuracy of the stress adjustment value.

[0083] 3. By combining the spring specifications and deformation deviation values ​​to determine the spacing deviation value, and distinguishing whether the amount of dust adhesion is less than the allowable adhesion amount, the spacing deviation adjustment value or the product of the adhesion deviation influence value is used as the deformation adjustment value, respectively. This realizes the linkage control between deformation adjustment and dust adhesion influence, making the deformation adjustment value more consistent with the actual deformation cause of the spring and improving the final calibration accuracy of the stress adjustment value.

[0084] Figure 1 This is a flowchart of the control method for an electric spring operating mechanism with a clutch. Detailed Implementation

[0085] The present invention will now be described in further detail with reference to the accompanying drawings and embodiments.

[0086] A control method for an electric spring-operated mechanism with a clutch is disclosed. This method collects data on switch opening and closing requirements, transmission specifications, spring specifications, stress detection values, historical switch usage parameters, switch environmental parameters, and spring displacement values. Based on the spring specifications, it determines energy storage and stress reference values. Combining stress deviation, historical usage parameters, and environmental parameters (temperature, humidity, dust) differences, it determines stress adjustment values ​​and refines the quantitative calculation logic for corrosion and dust effects. Subsequently, it monitors deformation trends using spring displacement values; if limits are exceeded, it supplements deformation adjustment values ​​and updates the stress adjustment values. Finally, it combines energy storage time and transmission specifications to output motor rotation parameters. This achieves precise matching between motor parameters and spring energy storage requirements, improving the operational stability and reliability of the electric spring-operated mechanism with a clutch, thereby reducing the probability of circuit failures.

[0087] Reference Figure 1 This invention discloses a control method for an electric spring operating mechanism with a clutch, comprising:

[0088] S1: Collect switch opening and closing requirements, transmission specifications, spring specifications, and stress test values.

[0089] Among them, switch opening and closing requirements refer to the instructions required for high-voltage switchgear to perform closing (connecting the circuit) or opening (disconnecting the circuit) operations. Switch opening and closing requirements include the types of opening and closing requirements and the energy storage time.

[0090] Transmission specifications refer to the specifications of the transmission devices between the motor and the energy storage spring when the motor drives the energy storage spring to store energy. Transmission specifications include the transmission ratio between the worm and the worm wheel, the transmission ratio between the worm wheel and the driven shaft pin, etc.

[0091] Spring specifications refer to the specifications and parameters of energy storage springs, such as spacing, material, stiffness, free length, rated compression stroke, rated load during energy storage, mean diameter, wire diameter, and rated energy storage capacity.

[0092] The stress test value refers to the stress test data of the energy storage spring.

[0093] Transmission specifications and spring specifications are obtained after being pre-input by the operator. Switch opening and closing requirements are obtained by acquiring electrical command signals from the control circuit of the high-voltage switch. Stress detection values ​​are obtained by collecting resistance strain gauges attached to the stress concentration area of ​​the energy storage spring.

[0094] S2: Determine the energy storage reference value and stress reference value according to the spring specifications.

[0095] The energy storage benchmark value refers to the standard value of the rated energy storage capacity of the spring determined to meet the power requirements for opening and closing high-voltage switches. The stress benchmark value refers to the standard stress value corresponding to the spring reaching the energy storage benchmark value.

[0096] The stiffness and rated compression stroke of the energy storage spring are obtained by referencing the spring specifications, and the energy storage baseline value is obtained by calculating using the elastic potential energy formula. Furthermore, the load, mean diameter, and wire diameter of the energy storage spring during rated energy storage are obtained by referencing the spring specifications, and the stress baseline value is obtained by calculating using the spring torsional shear stress formula, facilitating subsequent use.

[0097] S3: Calculate the difference between the stress test value and the stress reference value and use it as the stress deviation value.

[0098] Among them, the stress deviation value refers to the difference between the stress detection value and the stress reference value.

[0099] Calculating the stress deviation value facilitates subsequent use.

[0100] S4: Collect historical usage parameters of the switch.

[0101] Among them, the historical usage parameters of the switch refer to parameters such as the number of times the high-voltage switch was opened and closed and the usage time over a historical period. The historical usage parameters of the switch are obtained by querying the logs stored in the intelligent control module of the operating mechanism.

[0102] S5: Determine the stress reference deviation value based on the historical usage parameters of the switch, and check whether the stress deviation value is less than the stress reference deviation value. If yes, proceed to S6; if no, proceed to S7.

[0103] Among them, the stress reference deviation value refers to the reference value of stress deviation under the corresponding number of uses.

[0104] The number of uses is retrieved by accessing the switch history parameters and then entered into a preset database to match the stress reference deviation value for convenient subsequent use.

[0105] The greater the number of uses, the greater the corresponding stress reference deviation value. The number of uses database pre-stores a lookup table of different numbers of uses and their corresponding stress reference deviation values. The number of uses database is obtained by the operator performing stress tests on energy storage springs of the same specification at different numbers of uses and calculating the corresponding stress reference deviation values.

[0106] By judging whether the stress deviation value is less than the stress reference deviation value, it can be determined whether the stress deviation is normal.

[0107] S6: Determine the stress deviation adjustment value based on the stress deviation value, and use the stress deviation adjustment value as the stress adjustment value.

[0108] Among them, the stress adjustment value refers to the adjustment value corresponding to the energy storage when adjusting the energy storage capacity based on the actual stress condition of the energy storage spring. The stress deviation adjustment value refers to the adjustment parameter used to correct the energy storage reference value based on the stress deviation value.

[0109] When the stress deviation value is less than the stress reference deviation value, it indicates that the stress deviation is normal. Therefore, the product value between the stress deviation value and the preset stress energy storage correlation coefficient is calculated, and the calculation result is used as the stress deviation adjustment value. Then, the stress deviation adjustment value is used as the stress adjustment value to improve the accuracy of the obtained stress adjustment value.

[0110] The stress-energy storage correlation coefficient is derived from the fitting of experimental data on the stress and energy storage of springs of the same specification. It reflects the energy storage adjustment range corresponding to a unit stress deviation and usually ranges from 0.7 to 0.9.

[0111] S7: Collect switch environmental parameters, determine the environmental impact value based on the switch environmental parameters, determine the environmental adjustment value by combining the environmental impact value and the stress deviation value, and use the environmental adjustment value as the stress adjustment value.

[0112] Among them, switch environment parameters refer to the environmental characteristic parameters of the operating site of high-voltage switchgear and its supporting electric spring operating mechanism. These parameters include key indicators such as ambient temperature, ambient humidity, and ambient dust parameters (dust type and quantity of each type). Ambient temperature refers to the temperature at the operating site of the high-voltage switchgear and its supporting electric spring operating mechanism. Ambient humidity refers to the humidity at the operating site of the high-voltage switchgear and its supporting electric spring operating mechanism. Ambient dust parameters refer to the types and concentrations of dust at the operating site of the high-voltage switchgear and its supporting electric spring operating mechanism. These switch environment parameters are obtained through temperature and humidity sensors and dust concentration sensors pre-installed inside the high-voltage switchgear operating mechanism box and around the equipment.

[0113] Environmental impact value refers to a quantitative indicator used to characterize the comprehensive effect of environmental factors on spring stress. Environmental adjustment value refers to the adjustment value corresponding to the adjustment of energy storage capacity based on environmental impact.

[0114] When the stress deviation value is not less than the stress reference deviation value, it indicates that there is an abnormality in the stress deviation. Therefore, the switch environment parameters are collected and analyzed to determine the environmental impact value. Then, the product between the environmental impact value and the stress deviation value is calculated as the stress environment deviation value. Next, the product between the stress environment deviation value and the preset stress energy storage correlation coefficient is calculated, and the calculation result is used as the environmental adjustment value. Then, the environmental adjustment value is used as the stress adjustment value, thereby improving the accuracy of the obtained stress adjustment value.

[0115] To further ensure the rationality of the environmental impact value, it is necessary to conduct a further separate analysis and calculation of the environmental impact value, which will be explained in detail through the steps shown below.

[0116] The methods for determining environmental impact values ​​include the following steps:

[0117] S71: Retrieves ambient temperature, ambient humidity, and ambient dust parameters based on switch environmental parameters.

[0118] Among them, the ambient temperature, ambient humidity and ambient dust parameters can be retrieved by switching on and off, which is convenient for subsequent use.

[0119] S72: Determine the temperature effect value by combining the ambient temperature value and the spring specifications.

[0120] Among them, the temperature influence value refers to the quantitative index that characterizes the effect of the actual ambient temperature deviating from the rated operating temperature of the spring on the stress state of the spring.

[0121] The rated operating temperature range is retrieved by adjusting the spring specifications, and the ambient temperature value is judged to fall within the rated operating temperature range. When the ambient temperature value falls within the rated operating temperature range, a preset temperature reference influence value is output as the temperature influence value. When the ambient temperature value does not fall within the rated operating temperature range, the difference between the ambient temperature value and the rated operating temperature range is calculated as the temperature deviation value. Then, a temperature correction coefficient is selected based on the temperature deviation value. Finally, the absolute value of the temperature deviation value, the preset temperature stress coefficient, and the selected temperature correction coefficient are calculated as the product value as the temperature influence value, which facilitates subsequent use.

[0122] The temperature stress coefficient is obtained by fitting the temperature stress of the spring material through temperature stress experiments, reflecting the stress change corresponding to a unit temperature deviation. The temperature correction coefficient is selected based on the sign of the temperature deviation value; when the temperature deviation value is negative, the temperature correction coefficient is 0.8, and when the temperature deviation value is positive, the temperature correction coefficient is 1.

[0123] S73: Retrieve dust types and quantities of individual dust types based on environmental dust parameters.

[0124] Dust type refers to the category to which dust in the environment is classified. The amount of dust of a single type refers to the quantitative value of each type of dust per unit volume of the environment.

[0125] By retrieving the dust type and concentration from environmental dust parameters, and calculating the product between the dust concentration and the preset switch volume, the amount of dust of a single type is obtained for convenient subsequent use.

[0126] The switch volume refers to the volume corresponding to the electric spring operating mechanism, which is obtained after being pre-input by the operator.

[0127] S74: Determine the corrosion impact value and dust impact value by combining the ambient humidity value, dust type and the amount of single type of dust.

[0128] The corrosion impact value refers to the quantitative indicator of how corrosive dust (such as salt dust and acidic industrial dust) causes rust damage to the spring under the synergistic effect of environmental humidity, resulting in a reduction in the effective cross-section of the spring and thus an increase in stress. The dust impact value refers to the quantitative indicator of how non-corrosive dust (such as sand and sawdust) adheres to the spring surface under the influence of environmental humidity, increasing the spring's extension and contraction friction resistance and thus causing stress fluctuations.

[0129] By combining and analyzing environmental humidity values, dust types, and the amount of each type of dust, the corrosion impact value and dust impact value can be determined, which will facilitate subsequent use.

[0130] To further ensure the rationality of the corrosion impact value, it is necessary to perform a further separate analysis and calculation of the corrosion impact value, which will be explained in detail through the steps shown below.

[0131] The method for determining the corrosion impact value includes the following steps:

[0132] S741: Select a dust type that is consistent with the preset corrosion type and use it as the consistent type, and use the amount of dust of the single type corresponding to the consistent type as the consistent dust amount.

[0133] Among them, corrosion type refers to the type of dust that causes rust damage to the spring and reduces the effective cross-section of the spring. Corrosion types include salt dust, acidic industrial dust, etc.

[0134] By selecting and defining consistent types and amounts of dust, it becomes easier to use them later.

[0135] S742: Determine the humidity unit value and the number of consistent values ​​based on the consistent type.

[0136] Among them, the humidity unit value refers to the quantitative coefficient of the influence of unit ambient humidity change and unit dust amount on the intensity of corrosion of the same type of dust. The consistent value refers to the value corresponding to the same type.

[0137] By counting the consistent types and using the count results as the consistent number, and inputting the consistent types into a preset type database to match the humidity unit value, the humidity unit value can be obtained for convenient subsequent use.

[0138] The category database contains a pre-stored table of different consistent categories and their corresponding humidity unit values. The category database is obtained after the operator pre-enters the data.

[0139] S743: Determine if there is only one consistent value. If yes, proceed to S744; otherwise, proceed to S746.

[0140] In this process, by determining whether there is only one identical value, it is possible to determine whether different types of dust will affect each other.

[0141] S744: Determine the corrosion coefficient value by combining the ambient humidity value and the humidity unit value.

[0142] The corrosion coefficient value refers to the quantitative coefficient of corrosion impact caused by a unit amount of dust.

[0143] When there is only one consistent value, it indicates that there is no mutual influence between different types of dust. Therefore, the rated working humidity value is retrieved through the spring specification. When the ambient humidity value is less than the rated working humidity value, the humidity unit value is directly used as the corrosion coefficient value. When the ambient humidity value is greater than the rated working humidity value, the difference between the ambient humidity value and the rated working humidity value is calculated, and then the product of the difference and the humidity unit value is calculated as the corrosion coefficient value for convenient subsequent use.

[0144] S745: Calculate the product between the consistent dust amount and the corrosion coefficient value and use it as the single-type influence value, and use the single-type influence value as the corrosion influence value.

[0145] Among them, the single-type influence value refers to the influence value of a single dust type on the stress of the energy storage spring.

[0146] By calculating the product between the consistent dust amount and the corrosion coefficient value and using it as the single-type influence value, and then using the single-type influence value as the corrosion influence value, the accuracy of the obtained corrosion influence value is improved.

[0147] S746: Determine the coefficient values ​​for multiple types by combining consistent dust quantity and humidity unit values.

[0148] Among them, the multi-type coefficient value refers to the quantitative coefficient of the influence of the corrosion intensity under the synergistic effect of multiple corrosive dusts under a unit change in ambient humidity.

[0149] When there is only one consistent value, it indicates that different types of dust are influencing each other. Therefore, the consistent dust quantity and humidity unit value are analyzed together to determine the coefficient values ​​of various types for subsequent use.

[0150] To further ensure the rationality of the coefficient values ​​for multiple categories, it is necessary to perform further separate analysis and calculation on the coefficient values ​​for multiple categories, which will be explained in detail through the steps shown below.

[0151] The method for determining the coefficient values ​​of multiple categories includes the following steps:

[0152] S7461: Retrieve duration value based on consistent dust amount.

[0153] The duration value refers to the length of time that the dust type corresponding to the consistent dust amount continues to exist at the switch operation site.

[0154] The duration value is retrieved by maintaining a consistent dust level, which facilitates subsequent use.

[0155] S7462: Sort the duration values ​​from smallest to largest, and obtain the time sorting value based on the sorting result.

[0156] Among them, the time sort value refers to the result value after sorting according to time.

[0157] By sorting the duration values ​​from smallest to largest, and obtaining the time sorting value based on the sorting result, it is convenient for subsequent use.

[0158] S7463: Sort the dust content from smallest to largest based on the consistent dust amount, and obtain the content ranking value based on the ranking result.

[0159] Among them, the content ranking value refers to the result value corresponding to the ranking based on the amount of dust.

[0160] By sorting the uniform dust amount from smallest to largest, and obtaining the content ranking value based on the ranking result, it is convenient for subsequent use.

[0161] S7464: Calculate the sum between the time-ranked value and the content-ranked value and use it as the comprehensive ranking value.

[0162] The comprehensive ranking value refers to the ranking value after combining time and dust quantity.

[0163] The sum of the time-sorted value and the content-sorted value is calculated, and the result is used as the comprehensive sorting value for convenient subsequent use.

This spacing ratio value is then input into the spacing ratio database to match and obtain the adhesion influence value. Finally, the adhesion influence value is used as the dust influence value, thereby improving the accuracy of the obtained dust influence value.

[0192] The larger the spacing ratio value, the greater the adhesion effect value. The spacing ratio database has a pre-stored lookup table of different spacing ratio values ​​and their corresponding adhesion effect values. The spacing ratio database is obtained after the operator pre-inputs the data.

[0194] The comprehensive impact value refers to the impact value after taking into account temperature, corrosion, and dust.

[0195] By weighting the impact values ​​of temperature, corrosion, and dust, and using the calculated result as the comprehensive impact value, the accuracy of the obtained environmental impact value is improved.

[0228] Among them, the specification deformation reference value refers to the maximum allowable elastic deformation of the energy storage spring.

[0229] By inputting the spring specifications into a preset specification database, the specification deformation reference value is obtained for convenient subsequent use.

[0230] The specification database pre-stores a table of different spring specifications and their corresponding deformation reference values, which is obtained after the operator pre-inputs the data.

It reflects the energy storage adjustment range corresponding to a unit deformation deviation, and typically ranges from 5 to 8. The unit area is obtained after pre-input by the operator.

[0248] S7664: Use the spacing deviation adjustment value as the deformation adjustment value.

[0249] When the amount of dust adhering is less than the allowable amount, it means that the adhering dust will not have a synchronous impact. Therefore, the spacing deviation adjustment value is directly used as the deformation adjustment value to improve the accuracy of the obtained deformation adjustment value.
