[0009] The historical life evaluation module is used to perform life evaluation analysis on scrapped relays: marking the scrapped relays as evaluation objects, marking the evaluation objects as environment optimization objects or fixed value optimization objects; sending the environment optimization objects and fixed value optimization objects to the environment optimization analysis module and the fixed value optimization analysis module respectively;

[0010] The environmental optimization analysis module is used to optimize and analyze the operating environment of the relay: the operating environment parameter of the environmental optimization object is marked as analysis parameter i, i=1, 2, ..., n, n is a positive integer, and the environmental optimization value HYi of the analysis parameter i is marked; the environmental optimization value HYi of all analysis parameters i is sent to the operation protection module;

[0011] The set value optimization analysis module is used to optimize and analyze the protection set values ​​of the relay: generate a fault performance set, clean the fault performance set to obtain a state collapse value, and send the state collapse value to the operation protection module;

[0012] The operation protection module is used to perform operation protection analysis on the relay: the relay that needs operation protection is marked as a protection object, and environmental protection analysis and fixed value protection analysis are performed after the protection object completes each complete mechanical operation.

[0013] Furthermore, the specific process of marking the evaluation object as an environmental optimization object or a fixed value optimization object includes: obtaining the number of mechanical operations of the evaluation object and marking it as the life value of the evaluation object, retrieving the life evaluation threshold through the database, and comparing the life value with the life evaluation threshold: if the life value is less than the life evaluation threshold, the corresponding evaluation object is marked as an environmental optimization object; if the life value is greater than or equal to the life evaluation threshold, the corresponding evaluation object is marked as a fixed value optimization object.

[0014] Furthermore, the specific process of marking the environmental optimization value HYi of the analysis parameter i includes: marking the average value of the analysis parameter i of the environmental optimization object during the historical operation process as the environmental assessment value HPi of the analysis parameter i corresponding to the environmental optimization object, and marking the environmental optimization object as an out-of-control object or a stable object; comparing the analysis parameters i of the out-of-control object with those of the stable object: if the minimum value of the environmental assessment value HPi of the analysis parameter i of all out-of-control objects is greater than the maximum value of the environmental assessment value HPi of the analysis parameter i of all stable objects, then the minimum value of the environmental assessment value HPi of the analysis parameter i of all out-of-control objects is marked as the environmental optimization value HYi of the analysis parameter i; otherwise, the maximum value of the environmental assessment value HPi of the analysis parameter i of all stable objects is marked as the environmental optimization value HYi of the analysis parameter i.

[0015] Furthermore, the specific process of marking an environmental optimization object as an out-of-control object or a stable object includes: performing numerical calculation through the life assessment threshold to obtain a life stratification threshold, and comparing the life value of the environmental optimization object with the life stratification threshold: if the life value is less than the life stratification threshold, the corresponding environmental optimization object is marked as an out-of-control object; if the life value is greater than or equal to the life stratification threshold, the corresponding environmental optimization object is marked as a stable object.

[0016] Furthermore, the generation process of the fault manifestation set includes: dividing the 0-life assessment threshold into several mechanical operation intervals, obtaining the number of mechanical operations of the constant value optimization object during the operation within the mechanical operation interval and marking it as the fault value of the mechanical operation interval corresponding to the constant value optimization object, summing and averaging the fault values ​​of all constant value optimization objects corresponding to the mechanical operation interval to obtain the fault manifestation value of the mechanical operation interval, and the fault manifestation values ​​of all mechanical operation intervals constitute a fault manifestation set.

[0017] Furthermore, the specific process of cleaning the fault manifestation set includes: performing variance calculation on all elements in the fault manifestation set to obtain a manifestation concentration coefficient, and comparing the manifestation concentration coefficient with a preset manifestation concentration threshold: if the manifestation concentration coefficient is greater than or equal to the manifestation concentration threshold, then eliminating the maximum element and the minimum element in the fault manifestation set, and then recalculating the manifestation concentration coefficient, and so on, until the manifestation concentration coefficient is less than the manifestation concentration threshold; if the manifestation concentration coefficient is less than the manifestation concentration threshold, marking the maximum value of the maximum boundary value of the mechanical operation range corresponding to all elements retained in the fault manifestation set as a state collapse value; and sending the state collapse value to the operation protection module.

[0018] Furthermore, the specific process of environmental protection analysis includes: calculating the average value of the detection value of the analysis parameter i of the protected object during the historical operation process and marking it as the historical record value LSi, and calculating the setting threshold SZi of the analysis parameter i of the protected object during the next mechanical operation process through the historical record value LSi of the analysis parameter i and the environmental optimization value HYi: the environmental optimization value HYi is the average value of the setting threshold SZi and the historical record value LSi; the setting value of the analysis parameter i of the protected object during the next mechanical operation shall not exceed the setting threshold SZi.

[0019] Furthermore, the specific process of the fixed value protection analysis includes: marking the number of mechanical operations completed by the protected object as the execution value of the protected object, and determining whether the execution value of the protected object is less than the state collapse value: if so, no optimization processing is performed; if not, the various protection fixed value parameters of the protected object are proportionally reduced.

[0020] The present invention has the following beneficial effects:

[0021] 1. The historical life assessment module can be used to conduct life assessment analysis on scrapped relays. After the life values ​​of the assessment objects are counted, the assessment objects are differentiated and marked according to the life values, providing data support for the environmental optimization analysis process and the fixed value optimization analysis process;

[0022] 2. The environmental optimization analysis module can optimize and analyze the operating environment of the relay. Based on the secondary marking results of the environmental optimization object, the environmental assessment value HPi of the analysis parameter i of the out-of-control object and the stable object is compared. Based on the comparison results, the environmental optimization value HYi of the analysis parameter i is generated to optimize the subsequent operating environment parameter control of the relay;

[0023] 3. The setting optimization analysis module can optimize and analyze the protection setting of the relay. The fault values ​​of different mechanical operation intervals are statistically analyzed by generating a fault performance set. The fault performance set is then cleaned to obtain the state collapse value. The triggering timing of the subsequent protection setting optimization of the relay can be determined based on the state collapse value, thereby reducing the probability of operational failure of the relay.

[0024] 4. The operation protection module is used to perform operation protection analysis on the relay. After the protected object completes each complete mechanical operation, environmental protection analysis and fixed value protection analysis are performed respectively to ensure that the relay can operate in any environment and slow down its aging speed. When necessary, fixed value optimization is performed to improve the timeliness of early warning. BRIEF DESCRIPTION OF THE DRAWINGS

The analysis parameters i of the out-of-control objects are compared with those of the stable objects: if the minimum value of the environmental assessment values ​​HPi of the analysis parameters i of all the out-of-control objects is greater than the maximum value of the environmental assessment values ​​HPi of the analysis parameters i of all the stable objects, the minimum value of the environmental assessment values ​​HPi of the analysis parameters i of all the out-of-control objects is marked as the environmental optimization value HYi of the analysis parameter i; otherwise, the maximum value of the environmental assessment values ​​HPi of the analysis parameters i of all the stable objects is marked as the environmental optimization value HYi of the analysis parameter i; the environmental optimization values ​​HYi of all the analysis parameters i are sent to the operation protection module; the operating environment of the relay is optimized and analyzed, and the environmental assessment values ​​HPi of the analysis parameters i of the out-of-control objects and the stable objects are compared based on the secondary marking results of the environmental optimization objects, and the environmental optimization value HYi of the analysis parameter i is generated according to the comparison results, so as to optimize the subsequent operating environment parameter control of the relay.

[0032] The constant value optimization analysis module is used to optimize and analyze the protection constant values ​​of the relay: the 0-life assessment threshold is divided into several mechanical operation intervals, the number of mechanical operations of the constant value optimization object and the number of faults that occur during the operation within the mechanical operation interval are obtained and marked as the fault value of the mechanical operation interval corresponding to the constant value optimization object, the fault values ​​of all constant value optimization objects corresponding to the mechanical operation interval are summed and averaged to obtain the fault performance value of the mechanical operation interval, the fault performance values ​​of all mechanical operation intervals constitute a fault performance set, the variance of all elements in the fault performance set is calculated to obtain the performance concentration coefficient, and the performance concentration coefficient is compared with the preset performance concentration threshold: if the performance concentration coefficient is greater than or equal to the performance concentration threshold, the fault is The maximum element and the minimum element in the fault manifestation set are eliminated, and then the manifestation concentration coefficient is recalculated, and so on, until the manifestation concentration coefficient is less than the manifestation concentration threshold; if the manifestation concentration coefficient is less than the manifestation concentration threshold, the maximum value of the maximum boundary value of the mechanical operation interval corresponding to all elements retained in the fault manifestation set is marked as the state collapse value; the state collapse value is sent to the operation protection module; the protection setting of the relay is optimized and analyzed, and the fault values ​​of different mechanical operation intervals are statistically analyzed in a way of generating a fault manifestation set, and then the fault manifestation set is cleaned to obtain the state collapse value, so that the triggering timing of the subsequent relay protection setting optimization can be determined according to the state collapse value, thereby reducing the probability of relay operation failure.

[0033] The operation protection module is used to perform operation protection analysis on the relay: the relay that needs to be operated protected is marked as a protection object, and environmental protection analysis and fixed value protection analysis are performed after the protection object completes each complete mechanical operation. The specific process of environmental protection analysis includes: calculating the average value of the detection value of the analysis parameter i of the protection object during the historical operation process and marking it as the historical record value LSi, and calculating the setting threshold SZi of the analysis parameter i of the protection object during the next mechanical operation process through the historical record value LSi and the environmental optimization value HYi: the environmental optimization value HYi is the average value of the setting threshold SZi and the historical record value LSi; the setting value of the analysis parameter i during the next mechanical operation of the protection object shall not exceed the setting threshold SZi; for example, when the analysis parameter i is the air temperature, under normal circumstances, the air temperature of the protection object is generally set below 85°C. After the protection object completes a complete mechanical operation, if its historical record value LSi is 65°C and the environmental optimization value HYi is 70°C, then the air temperature of the environment of the protection object is set below 75°C when the protection object performs a mechanical operation next time, and the original setting of the analysis parameter i The fixed range is indented so that the protected object can achieve dynamic balance in the operating environment of the whole life process and slow down its aging speed; the specific process of fixed value protection analysis includes: marking the number of mechanical operations completed by the protected object as the execution value of the protected object, and judging whether the execution value of the protected object is less than the state collapse value: if so, no optimization is performed; if not, the various protection fixed value parameters of the protected object are proportionally reduced; the protection fixed value parameters include contact resistance, coil resistance, overcurrent protection accuracy, etc. For example, when the protection fixed value parameter is contact resistance, the value of the protection fixed value parameter is The value generally does not exceed 0.5Ω. When the execution value of the protected object is greater than or equal to the state collapse value, 0.5 ohms is proportionally reduced; when the protection fixed value parameter is the coil resistance, the value of the protection fixed value parameter is generally set to ±20% of the nominal value. When the execution value of the protected object is greater than or equal to the state collapse value, ±20% is proportionally reduced; after the protected object completes each complete mechanical operation, environmental protection analysis and fixed value protection analysis are carried out respectively to ensure that the relay can operate in what environment and slow down its aging rate, and perform fixed value optimization when necessary to improve the timeliness of early warning.
