Abstract

This invention discloses a method for coordinated regulation of thermal and humidity conditions in high-voltage switchgear, specifically relating to the field of high-voltage switchgear operation monitoring and thermal and humidity regulation technology. The method includes collecting temperature, humidity, partial discharge, current, and voltage data of the high-voltage switchgear during the current regulation cycle, as well as the current set of permissible regulation actions. This data is then organized according to the time of collection and the position within the switchgear, and a position record set is output. Based on the position record set, the order of temperature changes, humidity changes, and partial discharge changes at each position within the switchgear are compared sequentially according to the conductive connection sequence, airflow sequence, and insulation surface unfolding sequence. By sequentially unfolding the responses of multiple physical quantities before and after the restricted activation of existing permissible actions, the actual reach of the regulation borrowed actions and the subsequent follow-up range of abnormalities are distinguished, the true follow-up path of abnormalities within the switchgear and the weak points in thermal and humidity are identified, and the subsequent regulation targets are redefined accordingly.

Description

Technical Field

[0001] This invention relates to the field of high-voltage switchgear thermal and humidity regulation technology, and more specifically, to a method for coordinated regulation of high-voltage switchgear thermal and humidity conditions. Background Technology

[0002] In the operation and control of high-voltage switchgear, existing technologies mainly focus on detecting signs of heating, dampness, partial discharge, and insulation degradation in the switchgear as early as possible without interrupting power supply or changing the existing power supply and distribution links. Based on the monitoring results, timely organization of fan start-up and shutdown, heating and dehumidification, load adjustment, or alarm handling is carried out. In actual application, temperature, humidity, current, voltage, and partial discharge information are usually continuously collected. Local temperature fluctuations, humidity redistribution, and changes in electrical stress caused by the operation of fans, heating, or changes in operating mode are treated as interference quantities to avoid affecting the judgment of abnormal conditions. Taking the long-term continuous operation of rows of high-voltage cabinets in the traction power supply room of rail transit or the power distribution room of industrial plants as an example, on site, it is not allowed to apply additional load, moisture or forced disturbance tests in order to find out the hidden weak parts inside the cabinet, and the control side is required to use the existing permitted actions to complete the risk suppression within the safe range. However, under these conditions, a situation that can be directly verified repeatedly occurred on site: although the temperature at a local measuring point dropped after a certain fan was put into operation, although the humidity reading at a certain location decreased after a certain heating was put into operation, and although the partial discharge characteristics weakened after a certain load adjustment, the anomaly subsequently reappeared in adjacent areas, leeward locations of the structure, or weak insulation zones. This indicates that while the existing handling method reduces the side effects of the action, it also eliminates a few response information that can reveal the true path of the anomaly inside the cabinet and potential weak thermal and humidity locations. As a result, subsequent control can only be carried out around surface changes, making it difficult to accurately redefine the objects that truly need to be controlled without introducing additional high-risk tests. The technical problem to be solved by this application is: how to identify the expansion path of abnormal heat and humidity and the weak points of heat and humidity in the high-voltage cabinet by utilizing the changes in temperature and humidity response before and after the action is put into operation within the existing allowable adjustment action and operation safety boundary of the high-voltage cabinet, and to redefine the subsequent heat and humidity adjustment objects accordingly. Summary of the Invention

[0003] To overcome the aforementioned deficiencies of the prior art, embodiments of the present invention provide a method for coordinated regulation of the thermal and humidity state of a high-voltage switchgear. By sequentially expanding the temperature and humidity response changes before and after the existing permissible thermal and humidity regulation actions are initiated, the method distinguishes between the range reached by the regulation actions and the subsequent expansion range of thermal and humidity anomalies, identifies the expansion path of thermal and humidity anomalies within the switchgear and the weak points of thermal and humidity, and accordingly redefines the objects of subsequent thermal and humidity regulation, thereby solving the problems mentioned in the background art.

[0004] To achieve the above objectives, the present invention provides the following technical solution: a method for coordinated regulation of the thermal and humidity conditions of a high-voltage switchgear, comprising: S1. Collect temperature data, humidity data, partial discharge data, current data, voltage data and current allowable adjustment action set of the high voltage switch in the current adjustment cycle, and organize them according to the corresponding time of collection and the position in the switchgear, and output the position record set; S2. Based on the location record set, according to the conductive connection sequence, airflow sequence, and insulation surface unfolding sequence, perform sequential comparison of the temperature change sequence, humidity change sequence, and partial discharge change sequence of each location in the cabinet. Extract the location in the cabinet where the thermal and humidity change occurs first and has not been carried over by the previous change as the initial thermal and humidity abnormality location. Select the adjustment borrowing action that can be directly put into each initial thermal and humidity abnormality location from the current set of allowed adjustment actions, and output the borrowing record set. S3. For the borrowing record set, perform a restricted input for the corresponding adjustment borrowing action to form the thermal and humidity adjustment response of the current adjustment cycle, and simultaneously acquire the temperature change, current change, voltage change, humidity change and partial discharge change of each observation point before and after input, execute sequential expansion according to the order of response occurrence, and output the response sequence set. S4. Based on the response sequence set, perform forward connection comparison and reverse back pointing comparison on each observation position. Connect the observation positions that are consistent with the propagation sequence of the action borrowed by the regulation into an action arrival sequence. Connect the observation positions that appear later than the action arrival sequence and can be continuously connected along the position inside the cabinet into a thermal humidity anomaly extension sequence. Determine the starting position of the thermal humidity anomaly extension sequence as the thermal humidity weak position and output the regulation object set.

[0005] In a preferred embodiment, it further includes: S5. Based on the set of adjustment objects, apply the subsequent adjustment actions to the locations of each thermal and humidity weak point and the coverage locations of each thermal and humidity abnormality extension sequence, perform thermal and humidity state adjustment on the high-voltage switchgear, and after execution, obtain the temperature data, humidity data, partial discharge data, current data and voltage data of the corresponding locations again, perform verification in the same order comparison method as S2, and output the results of the current adjustment round.

[0006] In a preferred embodiment, S1 includes: S11. Sort the temperature data, humidity data, partial discharge data, current data and voltage data in the current adjustment cycle in ascending order according to the acquisition time, and extract the data items that contain both the acquisition time and the position in the cabinet from each type of data, and output the data column to be aligned. S12. For each data item in the data column to be aligned, perform column splitting search according to data type and cabinet position, and extract the other data items that have the same collection time as the data item; if there are other data items with the same collection time, merge the data item with the other data items with the same collection time into a record of the same time; if there are no other data items with the same collection time, extract the adjacent time data items before the data item and the adjacent time data items after the data item in the same cabinet position, and select one of them in a fixed order to correspond to the data item, and output the corresponding set of the same time. S13. Based on the corresponding set at the same time, temperature data, humidity data, partial discharge data, current data, voltage data, and the set of currently allowed adjustment actions at the same acquisition time and location in the same cabinet are written into the same record item, and the location record set is output.

[0007] In a preferred embodiment, S2 includes: S21. Based on the location record set, the locations inside the cabinet are sequentially numbered according to the conductive connection sequence, airflow sequence, and insulation surface unfolding sequence, and the temperature data, humidity data, and partial discharge data of the corresponding locations inside the cabinet are extracted according to the same sequential numbering at each acquisition time to form conductive sequence, airflow sequence, and surface sequence. S22. For each conductivity sequence, airflow sequence, and surface sequence, extract the temperature difference, humidity difference, and partial discharge difference of the same location in the cabinet between the previous and subsequent acquisition times, and sequentially retrieve the cabinet location where each difference first shows a non-zero change according to the sequential numbering; if there is no non-zero change of the same type in the preceding cabinet location in the same sequence before the first non-zero change corresponding to a certain cabinet location, record the cabinet location as the starting change position of the corresponding sequence and output the set of starting change positions; S23. Perform cross-correspondence on each initial change position in the initial change position set, extract the initial change positions pointing to the same position in the cabinet in the conductive order column, airflow order column and surface order column as initial abnormal positions, and extract the corresponding adjustment borrowing actions from the current set of allowed adjustment actions according to the correspondence between the position in the cabinet and the position of the action and the action execution status is allowed to be put into operation, and output the borrowing record set.

[0008] In a preferred embodiment, S3 includes: S31. Based on the borrowing record set, perform a restricted input for each regulation borrowing action, and extract the temperature data, current data, voltage data, humidity data, and partial discharge data of each observation position at the adjacent time before and after the action start time using the action start time, action end time, action position, and observation position set as indexes. Solve the corresponding temperature change direction, current change direction, voltage change direction, humidity change direction, and partial discharge change direction respectively, and output the observation position change table. S32. Based on the observation position change table, construct motion propagation candidate edges according to the conductive connection sequence, airflow passage sequence, and insulation surface unfolding sequence, and perform sequence consistency check, reverse back-point elimination, and breakpoint continuation search on each motion propagation candidate edge. Connect the motion propagation candidate edges that satisfy the condition that the previous position has responded, the subsequent position has responded, and there is no recorded reverse relationship between the two positions into a candidate propagation chain. Stop connecting when the newly added motion propagation candidate edge is empty, and output the candidate propagation chain set.

[0009] In a preferred embodiment, S3 further includes: S33. For the candidate propagation chain set, according to the fixed field order of temperature change direction, current change direction, voltage change direction, humidity change direction and partial discharge change direction, perform item-by-item consistency check and conflict resolution on the multi-field response of the same observation position. When the previous field has formed a chain position and the next field has a reverse retracement, delete the chain position corresponding to the next field. When the previous field has not formed a chain position and the next field forms a continuous connection, retain the chain position corresponding to the next field and write the retention result back to the candidate propagation chain set, and output the consistent response chain set. S34. Based on the consistent response chain set, perform double-order expansion according to the time sequence from the start time of the action to the end time of the action and the chain position sequence. Record the time when each observation position first enters the consistent response chain set as the response occurrence time, and write it into each observation position according to the response occurrence time, chain position sequence and cabinet position sequence, and output the response sequence set.

[0010] In a preferred embodiment, S4 includes: S41. Based on the response sequence set, with the position of the adjustment borrowing action as the starting position, perform forward timing retrieval on each observation position according to the conductive connection sequence, airflow sequence, and insulation surface unfolding sequence, extract candidate subsequent positions whose response occurrence time is later than the starting position and whose positions in the cabinet are continuous, and simultaneously extract the reverse candidate relationship of each candidate subsequent position pointing back to the previous position, and output the forward candidate table and the back-pointing candidate table. S42. Solve the consistency constraints for each candidate position by using the forward candidate list and the back-pointing candidate list. The consistency constraints include shifting the response occurrence time sequentially from the previous position to the next position, retaining only one incoming edge and one outgoing edge for the same observation position, ensuring that there are no intermediate observation positions of the same order that are not connected to the chain between the previous and the next positions, and pointing back to the previous position that has been connected to the chain. When the consistency constraints are satisfied, the corresponding candidate position is connected to the tail of the chain and the tail position is updated. When there are no candidate positions that satisfy the consistency constraints, the connection is stopped and the action arrival sequence is output.

[0011] In a preferred embodiment, S4 further includes: S43. Based on the action arrival sequence, extract the observation bits whose response time is later than the corresponding chain position response time and have not been written into the action arrival sequence from the response sequence set. Perform chain access according to the same cabinet position continuity constraint, time shift constraint and back finger closure constraint as S42. Connect the observation bits subsequently received by the same chain tail position into a thermal and humidity anomaly extension sequence. When the same observation bit enters different thermal and humidity anomaly extension sequences at the same time, perform fixed sequence resolution according to the conductive connection sequence, airflow sequence and insulation surface unfolding sequence, and output thermal and humidity anomaly extension sequence set. S44. Perform first-position verification on each thermal humidity anomaly extension sequence through the thermal humidity anomaly extension sequence set, determine the first observation position in each thermal humidity anomaly extension sequence that is disconnected from the action arrival sequence and is followed by at least one subsequent observation position as the thermal humidity weak position, and merge the corresponding action arrival sequence, thermal humidity anomaly extension sequence and thermal humidity weak position into the same control object record, and output the regulation object set.

[0012] In a preferred embodiment, S5 includes: S51. Based on the set of adjustment objects, perform sequential sorting of the locations of each thermal and moisture weak point and the coverage locations of each thermal and moisture abnormality expansion sequence. Arrange the locations of the thermal and moisture weak points first, and arrange the coverage locations of the thermal and moisture abnormality expansion sequence last. Write the same type of locations in order of conductive connection, airflow passage, and insulation surface unfolding. Bind each location to the corresponding subsequent action execution location in the current set of allowed adjustment actions, and output the subsequent action table. S52. Based on the subsequent action table, perform heat and humidity adjustment for each subsequent action in the order of writing in the subsequent action table, and obtain the temperature data, humidity data, partial discharge data, current data and voltage data of the corresponding location after each subsequent action is executed. Combine the records before and after each subsequent action is executed according to the action order and the location in the cabinet, and output the verification record set. S53. Based on the verification record set, and following the same conductive connection sequence, airflow sequence, and insulation surface unfolding sequence as in S2, re-perform the sequential comparison of temperature change, humidity change, and partial discharge change at each corresponding position. Record the position that no longer enters the initial abnormal position as the adjustment completion position, and record the position that still enters the initial abnormal position as the adjustment continuation position. Combine and write the adjustment completion position, adjustment continuation position, and their corresponding subsequent actions, and output the result of the current adjustment round.

[0013] The technical effects and advantages of this invention are as follows: 1. This scheme, by performing sequential analysis on the response changes before and after the restricted input of the regulation borrowing action, and distinguishing between the action arrival sequence and the thermal and humidity anomaly expansion sequence, can identify the true following path and thermal and humidity weak points without applying additional high-risk disturbances, thereby relatively improving the accuracy of subsequent re-determination of the regulation target. 2. The temperature, humidity, partial discharge, current and voltage are organized according to the time of acquisition and their position in the cabinet to form a unified location record set. This can reduce the impact of time drift and position mismatch of multi-source data on the sequential comparison, thereby relatively improving the consistency of subsequent anomaly identification. 3. Extracting the initial change position along the conductive connection sequence, airflow sequence, and insulation surface unfolding sequence, and cross-determining the initial anomaly position, can reduce the interference of local deviations under a single observation path on anomaly location, thereby making the adjustment borrowing action selection closer to the actual anomaly starting point. 4. Construct candidate propagation chains for the direction of change of observed position, and perform sequential consistency verification, reverse retracement elimination, and breakpoint continuation retrieval. This can screen out invalid connections and reverse disturbances in the propagation process of adjustment borrowing actions, thereby relatively improving the interpretability of response path solution. 5. Performing item-by-item consistency checks and conflict resolution on the candidate propagation chain set in a fixed field order can reduce chain position confusion caused by inconsistencies in the responses of multiple physical quantities, thus making the resulting consistent response chain set more suitable as a direct basis for response sequence expansion. 6. Apply subsequent actions to the location of the weak points in heat and humidity and the coverage of the heat and humidity anomaly extension sequence, and perform verification in the same order comparison method as the previous sequence. This can distinguish between the adjustment completion point and the adjustment continuation point, thereby forming a complete control result that can be inherited to the next control round.

[0015] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0016] Refer to the instruction manual appendix Figure 1 The high-voltage switchgear thermal and humidity state coordinated adjustment method of the present invention includes: S1. Collect temperature data, humidity data, partial discharge data, current data, voltage data and current allowable adjustment action set of the high voltage switch in the current adjustment cycle, and organize them according to the corresponding time of collection and the position in the switchgear, and output the position record set; In this embodiment, S1 is used to organize temperature data, humidity data, partial discharge data, current data, and voltage data that are not completely consistent within the current adjustment cycle into a set of position records that can be directly read for subsequent sequential comparison. During processing, the current adjustment cycle number, the start time of this cycle, and the end time of this cycle are first locked. Then, a unified position index table and the currently allowed adjustment action set are called. The unified position index table includes at least the cabinet position number, the compartment it belongs to, the positions before and after conductive connections, the positions before and after airflow, and the positions before and after insulation surfaces. The currently allowed adjustment action set includes at least the action number, action type, action execution status, action location, and the allowed input mark for this cycle. Subsequently, only the acquisition records with consistent cycle numbers and acquisition times between the start and end times of this cycle are retained. This implementation process includes the following steps: S11 is used to form the basic data column corresponding to the same moment; the input is the temperature data, humidity data, partial discharge data, current data, and voltage data within the current adjustment cycle; the processing actions include creating data columns according to data type, arranging them in ascending order according to the acquisition time, retaining the first record in the original writing order and writing the remaining records into the duplicate record table when the acquisition time is the same, and then extracting the data items that have both the acquisition time and the cabinet position number; the output is the data column to be aligned, which must include at least the current adjustment cycle number, data type, acquisition time, cabinet position number, and record value, and is written to S12 for reading; records that lack an acquisition time or cabinet position number are written into the missing record table and are not included in the data column to be aligned; S12 is used to generate a unique same-time correspondence result for each data item; the input is the data column to be aligned and the unified location index table; the processing actions include, for each data item in the data column to be aligned, searching for data items in other data types that have the same collection time and the same location number in the cabinet according to the cabinet location number; when there are data items with the same collection time, the current data item is merged with the data item to form a same-time record; when there are no data items with the same collection time, the most recent data item before the current data item and the most recent data item after the current data item under the same location number in the cabinet are extracted respectively. When both exist, the previous data item is selected in a fixed order of first and last; when only the previous data item exists, the previous data item is selected; when only the next data item exists, the next data item is selected; when neither exists, a missing field mark is written; the output is the same-time correspondence set, which is written to S13 for reading; when there are multiple data items with the same collection time in the same data type, the first record is retained according to the original writing order, and the remaining records are written to the duplicate correspondence table; S13 is used to generate a location record set; the input quantities are the corresponding set at the same time and the set of currently allowed adjustment actions; the processing actions include grouping according to the reference acquisition time and the cabinet position number, writing the temperature data, humidity data, partial discharge data, current data and voltage data under the same reference acquisition time and the same cabinet position number into the same record item, and then writing the action number, action type, action execution status and the allowed input mark of this round into the record item, which are consistent with the action position of the action in the current allowed adjustment action set and the cabinet position number; the output quantity is the location record set, which includes at least the current adjustment round number, acquisition time, cabinet position number, temperature data, humidity data, partial discharge data, current data, voltage data, corresponding action field, missing field mark and replenishment source mark, and writes it into S2 for reading; when there is no corresponding action, write an empty action mark, and record items with missing field marks are retained, but missing fields do not participate in subsequent non-zero change calculations; Through the above processing, S1 completes the unified sorting, synchronous correspondence, and position merging of multiple physical quantity data within the current adjustment cycle, obtaining a position record set, which provides a unified input basis for the sequential comparison in S2. In practical applications: when the temperature, humidity, and current data are collected at 10:00:05, the partial discharge data is collected at 10:00:04, and the voltage data is collected at 10:00:06, under the same cabinet position number, S11 first completes the sorting and duplicate record removal. S12 uses 10:00:05 as the corresponding benchmark, selects the partial discharge data at 10:00:04 and the voltage data at 10:00:06 to complete the synchronous correspondence. S13 then writes the five types of data and the current allowed action corresponding to the position into the same record item, forming a position record set that S2 can directly read.

[0017] S2. Based on the location record set, according to the conductive connection sequence, airflow sequence, and insulation surface unfolding sequence, perform sequential comparison of the temperature change sequence, humidity change sequence, and partial discharge change sequence of each location in the cabinet. Extract the location in the cabinet where the thermal and humidity change occurs first and has not been carried over by the previous change as the initial thermal and humidity abnormality location. Select the adjustment borrowing action that can be directly put into each initial thermal and humidity abnormality location from the current set of allowed adjustment actions, and output the borrowing record set. In this embodiment, S2 is used to identify the initial abnormal position within the current adjustment cycle based on the position record set, and select the adjustment borrowing action that can be directly applied for each initial abnormal position. The processing principle is to first establish independent sequences for the positions in the same cabinet according to the conductive connection sequence, airflow sequence, and insulation surface unfolding sequence, and then compare the changes in temperature data, humidity data, and partial discharge data at the time of collection before and after each sequence column, extract the initial change position that appears first in each sequence column and has not been taken over by the previous position, and finally perform cross-correspondence on the three types of initial change positions, and complete the adjustment borrowing action binding in combination with the current allowed adjustment action set. This implementation process includes the following steps: S21 is used to expand the location record set into three directly comparable priority columns; the inputs are the location record set, the unified location index table, and the current adjustment cycle number; the processing actions include: first, extracting the record item whose cycle number matches the current adjustment cycle number from the location record set; then reading the cabinet position number, conductivity priority number, airflow priority number, and surface priority number from the unified location index table, where the cabinet position number is unique and fixed in the unified location index table, and the conductivity priority number, airflow priority number, and surface priority number each independently correspond to the same cabinet position number; subsequently, grouping by acquisition time, and at each acquisition time, extracting the temperature and humidity data corresponding to the cabinet position number based on the conductivity priority number, airflow priority number, and surface priority number. The system records partial discharge data and writes it in ascending order of rank number. The output consists of a conductivity rank column, an airflow rank column, and a surface rank column. Each rank column contains at least the current adjustment cycle number, acquisition time, cabinet position number, corresponding rank number, temperature data, humidity data, and partial discharge data, which are then written to S22 for reading. The system handles anomalies or missing data as follows: if a cabinet position number has a position record at a certain acquisition time but the temperature data, humidity data, or partial discharge data has a missing field marker, the record is retained, but the missing field is marked as not eligible for change calculation. If a cabinet position number has no corresponding record at a certain acquisition time, the record is not created, but is only marked as empty in the rank column at that acquisition time. S22 is used to extract the initial change position from three types of sequential columns; the input quantities are the conductivity sequential column, the airflow sequential column, and the surface sequential column; the processing actions include: extracting the temperature data, humidity data, and partial discharge data of the same cabinet location number at the previous and subsequent acquisition times for each sequential column according to the acquisition time sequence, calculating the temperature difference, humidity difference, and partial discharge difference respectively, where the difference between the recorded value at the later acquisition time and the recorded value at the previous acquisition time is the corresponding difference value, and if the difference is not equal to zero, it is recorded as a non-zero change, and if the difference is equal to zero, it is recorded as a zero change, without introducing threshold comparison; then, in each sequential column, the records where the temperature difference, humidity difference, and partial discharge difference of each cabinet location number first show a non-zero change are retrieved in ascending order of sequential number; Before the first non-zero change of a cabinet location number, if there is no first non-zero change of the same type of cabinet location number in the same priority column with a priority number preceding it, the cabinet location number is recorded as the starting change position of that priority column. If multiple cabinet location numbers in the same priority column simultaneously exhibit the same type of non-zero change for the first time at the same acquisition time, the cabinet location number that appears first in ascending priority number is retained as the starting change position, and the remaining cabinet location numbers are recorded as parallel change positions but not written into the starting change position set. The output quantity is the starting change position set, which includes at least the priority column type, cabinet location number, corresponding acquisition time, change type, and corresponding difference value, and is written to S23 for reading. Abnormal or missing handling is as follows: when a cabinet location number contains a missing field marker in the previous or subsequent acquisition time, that field is not included in the corresponding difference value calculation; when a priority column has not formed any starting change positions in the current adjustment cycle, an empty priority result marker is written to that priority column. S23 is used to determine the initial abnormal position from the initial change position set and bind the adjustment borrowing action; the input quantities are the initial change position set, the currently allowed adjustment action set, and the unified position index table; the processing actions include: first, performing cross-correspondence on each initial change position in the initial change position set according to the cabinet position number, and prioritizing the extraction of the same cabinet position number that appears simultaneously in the conductivity order column, airflow order column, and surface order column as the initial abnormal position; when no three columns of corresponding results are extracted, the corresponding results of the conductivity order column and airflow order column, the corresponding results of the conductivity order column and surface order column, and the corresponding results of the airflow order column and surface order column are extracted in sequence as the initial abnormal position; when there are still no corresponding results, the current adjustment... In each round, no initial abnormal bit is generated, and a crossover failure flag is written. After the initial abnormal bit is generated, actions whose action position matches the cabinet position number of the initial abnormal bit and whose action execution status is allowed to be put into operation are retrieved from the current set of allowed adjustment actions as candidate adjustment borrowing actions. When there are multiple candidate adjustment borrowing actions, the first action is retained according to the writing order in the current set of allowed adjustment actions. When there is no allowed action with the same action position, actions whose action position matches the cabinet position number before or after the initial abnormal bit and whose action execution status is allowed to be put into operation are retrieved, and the first action is retained according to the writing order in the current set of allowed adjustment actions. Subsequently, an observation set is developed around the initial anomaly position. The observation set includes at least the initial anomaly position, the location of the adjustment borrowing action, and the cabinet position numbers located one position before and one position after the initial anomaly position's conductivity sequence number, airflow sequence number, and surface sequence number in the unified position index table. Duplicate cabinet position numbers are retained only once. The output is a borrowing record set, which includes at least the current adjustment cycle number, the initial anomaly position, the adjustment borrowing action, the location of the adjustment borrowing action, and the observation set. This record set is then written to S3 for reading. The handling of anomalies or missing information is as follows: when the initial anomaly position has been generated but no permitted adjustment borrowing action has been found, the initial anomaly position is retained, and the adjustment borrowing action field is marked as an empty action, while a "pending manual handling" mark is also written. Through the above processing, S2 converts the position record set into the initial change position under the conductive connection sequence, airflow sequence, and insulating surface unfolding sequence, and further solves the initial abnormal position and adjustment borrowing action to form a borrowing record set for S3 to read directly; this processing ensures that the source of the initial abnormal position is clear, the order is consistent, parallel changes can be resolved, and empty results can be written back, avoiding the lack of positioning basis for subsequent adjustment borrowing actions; In practical applications: When, in a given adjustment cycle, position P03 inside the cabinet first shows a non-zero temperature difference in the conductivity, airflow, and surface order columns, and its preceding position does not show a similar non-zero change, S22 records P03 into the three types of initial change positions, and S23 determines P03 as the initial abnormal position accordingly; if there are fan and heating actions with the same action position P03 in the current allowed adjustment action set and their execution status is allowed to be put into operation, then the action that ranks first in the current allowed adjustment action set is selected as the adjustment borrowing action, and P03 and its preceding and following positions in the three order columns are written into the observation position set, and finally the corresponding borrowing record set is generated for S3 to perform a restricted input.

[0018] S3. For the borrowing record set, perform a restricted input for the corresponding adjustment borrowing action to form the thermal and humidity adjustment response of the current adjustment cycle, and simultaneously acquire the temperature change, current change, voltage change, humidity change and partial discharge change of each observation point before and after input, execute sequential expansion according to the order of response occurrence, and output the response sequence set. In this embodiment, S3 is used to perform a restricted input on the adjustment borrowing action in the borrowing record set, and organize the changes of multiple physical quantities before and after the adjustment borrowing action into a response sequence set that can be directly read for subsequent path identification; the processing principle is to first lock the start time, end time, action position, and observation position set of the adjustment borrowing action within the current adjustment round, and then solve the change direction of the temperature data, current data, voltage data, humidity data, and partial discharge data of each observation position before and after the start time of the action; then, candidate propagation chains are constructed according to the conductive connection sequence, airflow sequence, and insulation surface unfolding sequence, and consistency verification and conflict resolution are performed on the multi-field response; finally, the response sequence set is unfolded according to the time sequence and chain position sequence; the implementation process includes the following steps: S31 is used to generate the observation position change table. Its working mechanism is to bind a restricted input of the adjustment borrowing action with the adjacent records before and after each observation position to form a unified direction change input. The input quantities are the borrowing record set, the position record set, and the current adjustment round result cache. The processing actions include: performing a restricted input on each adjustment borrowing action in the borrowing record set in the writing order, wherein a restricted input is limited to performing a write on only one adjustment borrowing action in the current adjustment round, and no second adjustment borrowing action is superimposed before the end of the adjustment borrowing action; the time when the adjustment borrowing action is written is recorded as the action start time, and the time when the end state of the adjustment borrowing action is first written back is recorded as the action end time. If the end state is not written back, the end time of the current adjustment round is used instead. Then, using the start time, end time, action location, and observation set as indexes, extract the temperature, current, voltage, humidity, and partial discharge data from the most recent record before and after the start time of the action for each observation location in the location record set. For each field, subtract the previous record value from the next record value; a difference greater than zero indicates an upward movement, a difference less than zero indicates a downward movement, and a difference equal to zero indicates no change. The output is an observation location change table, which includes at least the current regulation cycle number, the regulation borrowed action number, the start time, the end time, the action location, the observation location, the direction of temperature change, the direction of current change, the direction of voltage change, the direction of humidity change, and the direction of partial discharge change, and writes it to S32 for reading. Abnormal or missing data handling is as follows: if there is no corresponding record for an observation location before or after the start time of the action, write the corresponding field of that observation location into a missing direction marker and do not participate in subsequent candidate edge generation; if multiple records with the same time exist on the same side for the same observation location, retain the first record according to the original writing order. S32 is used to construct candidate propagation chains from the observation position change table. Its working mechanism is to extract action propagation candidate edges that satisfy the sequential relationship along three types of sequences, and form verifiable propagation chains through consistent verification, back-point elimination, and breakpoint continuation. The input quantities are the observation position change table, the unified position index table, and the adjustment borrowed action action position. The processing actions include: reading the sequence number of the observation position in the unified position index table according to the conductive connection sequence, the airflow passage sequence, and the insulation surface unfolding sequence, respectively, and generating action propagation candidate edges only for two observation positions corresponding to adjacent sequence numbers. When generating candidate edges, the preceding position must have recorded any non-missing direction among the temperature change direction, current change direction, voltage change direction, humidity change direction, or partial discharge change direction, and the subsequent position must have recorded a non-missing direction at its subsequent time. Subsequently, each action propagation candidate edge is sequentially subjected to sequence consistency verification, reverse retrieval elimination, and breakpoint continuation retrieval. Sequence consistency verification is used to confirm that the previous position response is earlier than the subsequent position response. Reverse retrieval elimination is used to delete candidate edges that have been connected to the previous position except for those where the subsequent position has already pointed back to the previous position. Breakpoint continuation retrieval is used to search for the observation position corresponding to the next next sequence number when the adjacent subsequent positions do not meet the access conditions. If the next next observation position satisfies the condition of the previous position responding, the subsequent position responding, and the intermediate breakpoint position not recording a reverse relationship, then the previous position and the next next observation position form a continuation edge, and the intermediate breakpoint position is recorded as missing. Action propagation candidate edges that do not have a recorded reverse relationship are connected to form a candidate propagation chain. The connection stops when the newly added action propagation candidate edge is empty. The output is a candidate propagation chain set, which includes at least the chain number, sequence type, chain position order, previous observation position, next observation position, whether to continue the edge, and missing mark. It is written to S33 for reading. The abnormal or missing handling is as follows: when the position of the adjustment borrowing action does not appear in the observation position change table, the observation position that first appears in the observation position set without missing direction record is taken as the chain start position. When no candidate edge is generated for any of the three types of sequences, an empty candidate propagation chain mark is written to the adjustment borrowing action. S33 is used to extract a consistent response chain set from the candidate propagation chain set. Its mechanism is to perform item-by-item consistency verification and conflict resolution on the multi-field responses of the same observation position through a fixed field order, retaining only the chain positions that can support the same propagation direction. The inputs are the candidate propagation chain set and the observation position change table. The processing actions include: checking the multi-field responses of the same observation position in the candidate propagation chain set item by item according to the fixed field order of temperature change direction, current change direction, voltage change direction, humidity change direction, and partial discharge change direction; when the previous field in the fixed field order has formed a chain position in the candidate propagation chain set and the corresponding chain position of the next field has a reverse retracement, the corresponding chain position of the next field is deleted; when the previous field has not formed a chain position and the corresponding chain position of the next field satisfies the continuous connection between the previous and next observation positions, the corresponding chain position of the next field is retained. When the same observation position simultaneously forms a retrievable chain position in all three sequences, one chain position is retained in a fixed order: first the conductive connection sequence, then the airflow sequence, and finally the insulation surface unfolding sequence; the remaining chain positions are deleted. The retention result is written back to the candidate propagation chain set. The output is a consistent response chain set, which includes at least the chain number, retention sequence type, chain position sequence, observation position, retention field type, and corresponding change direction, and is written to S34 for reading. The abnormal or missing handling is as follows: if all fields of an observation position are missing direction markers, it is not written to the consistent response chain set; if an observation position is deleted due to conflicts in all fields in the fixed field sequence, the observation position is recorded as a conflict rejection position and will no longer participate in subsequent unfolding. S34 is used to generate a response sequence set from a consistent response chain set. Its working mechanism is to expand the first entry time of each observation bit in the consistent response chain set into a unique response order according to the time order and chain position order. The input quantities are the consistent response chain set, the observation bit change table, the action start time, and the action end time. The processing actions include: firstly, using the action start time to the action end time as the time range, searching for the first entry record of each observation bit in the observation bit change table in the consistent response chain set, and recording the first entry time into the consistent response chain set as the response occurrence time of that observation bit. Then, perform double-sequence expansion and write according to the ascending order of response occurrence time, chain position order, and cabinet position number; multiple observation positions under the same response occurrence time are first sorted according to chain position order, and those with the same chain position order are then sorted according to cabinet position number; the output is a response sequence set, which includes at least the current adjustment round number, adjustment borrowing action number, response occurrence time, chain position order, cabinet position number, sequence type, and corresponding change direction, and is written to S4 for reading; the abnormal or missing handling is as follows: if the consistent response chain set contains only the starting position, the starting position is still written to the response sequence set; if the consistent response chain set is empty, an empty response sequence mark is written to the adjustment borrowing action and the process stops entering S4; Through the above processing, S3 completes the limited input of the regulation borrowing action, the calculation of the direction of the observed position change, the construction of the candidate propagation chain, the multi-field consistency check and the expansion of the response sequence, and obtains a set of response sequences that can be directly read by S4. This processing ensures that the start and end times of the regulation borrowing action are clear, the direction definition is unified, the propagation chain generation is verifiable, and the conflict chain position can be resolved, avoiding the lack of verifiable input for subsequent action arrival sequences and thermal and humidity anomaly extension sequences. In practical applications: When a certain adjustment borrowing action is the action of the fan inside the cabinet, the action position is P03, and the observation position set includes P03 and its preceding and following positions in the conductive connection sequence, airflow passage sequence, and insulation surface unfolding sequence, S31 first solves the temperature change direction, current change direction, voltage change direction, humidity change direction, and partial discharge change direction of each observation position in the most recent records before and after the action start time; S32 then generates action propagation candidate edges along the three types of sequences, and allows the search of the observation position corresponding to the next sequence number to form a continuation edge when the adjacent subsequent position does not meet the conditions; S33 then deletes the reverse back-pointing chain positions and retains the continuous receiving chain positions according to the fixed field order of temperature change direction, current change direction, voltage change direction, humidity change direction, and partial discharge change direction; S34 finally writes the observation position that first enters the chain into a response sequence set according to the response occurrence time, chain position sequence, and cabinet position number, for S4 to continue to identify the action arrival sequence and thermal and humidity anomaly expansion sequence.

[0019] S4. Based on the response sequence set, perform forward connection comparison and reverse back pointing comparison on each observation position. Connect the observation positions that are consistent with the propagation sequence of the action borrowed by the regulation into an action arrival sequence. Connect the observation positions that appear later than the action arrival sequence and can be continuously connected along the position inside the cabinet into a thermal humidity anomaly extension sequence. Determine the starting position of the thermal humidity anomaly extension sequence as the thermal humidity weak position and output the regulation object set. In this embodiment, S4 is used to solve the action arrival sequence of the adjustment borrowing action, the thermal and humidity anomaly expansion sequence, and the thermal and humidity weak point based on the response sequence set, and to generate an adjustment object set for subsequent thermal and humidity adjustment to be directly read. The processing principle is as follows: first, starting from the position of the adjustment borrowing action or its alternative starting position, forward candidate relations and back-pointing candidate relations are extracted under the conductive connection sequence, airflow sequence, and insulation surface unfolding sequence, respectively, and then the action arrival sequence is entered according to unified constraints; subsequently, the thermal and humidity anomaly expansion sequence is extracted from subsequent responses that have not entered the action arrival sequence, and a fixed-order resolution is performed on the parallel entry results; finally, the first-position verification is performed on each thermal and humidity anomaly expansion sequence to obtain the thermal and humidity weak point and write it into the adjustment object set. This implementation process includes the following steps: S41 is used to generate forward candidate tables and back-pointing candidate tables. Its working mechanism is to convert the temporal and positional relationships in the response sequence set into candidate access relationships that can be solved subsequently. The inputs are the response sequence set, the borrowed record set, and the unified position index table. The processing actions include: first reading the position of the adjustment borrowing action and using it as the starting position; when the position of the adjustment borrowing action does not appear in the response sequence set, extracting the earliest observation position of the response occurrence time from the response sequence set as the replacement starting position, and recording the position of the adjustment borrowing action as the non-response position. Subsequently, forward temporal retrieval is performed on each observation position in the response sequence set according to the conductive connection sequence, airflow sequence, and insulating surface unfolding sequence. Only observation positions whose response occurrence time is later than the starting position and whose sequence number is continuous with the preceding position are extracted as candidate subsequent positions. By default, continuous is defined as adjacent sequence numbers in the same sequence. While extracting candidate subsequent positions, it is checked whether there is a retracement record pointing back to the preceding position. If so, it is written into the retracement candidate relationship. The output is a forward candidate table and a retracement candidate table. The forward candidate table includes at least the sequence type, the preceding observation position, the subsequent observation position, the occurrence time of the preceding response, and the occurrence time of the subsequent response. The retracement candidate table includes at least the sequence type, the subsequent observation position, and the retracement preceding position. The forward candidate table and the retracement candidate table are written into S42 for reading. The abnormal or missing handling is as follows: if there is no candidate subsequent position under a certain sequence, an empty candidate mark is written to that sequence; if the same candidate subsequent position corresponds to multiple preceding positions, all of them are retained and left for unified solution by S42. S42 is used to solve the action arrival sequence from the forward candidate list and the retrace candidate list. Its working mechanism is to perform consistency constraint solving on the candidate successors in a fixed order, and only retain the access results that satisfy the continuity of action propagation. The inputs are the forward candidate list, the retrace candidate list, the substitute start position, or the position of the action borrowed for adjustment. The processing actions include: taking the start position as the chain head, performing consistency constraint solving on the candidate successors in sequence. The consistency constraints include the successor response time being later than the previous response time, only one incoming edge and one outgoing edge being retained for the same observation position, there being no intermediate observation positions in the same order between the previous and successors that are not connected to the chain and whose order number is between the two, and the retrace candidate relationship pointing to the previous position that has been connected to the chain. During the solution, the following order is checked in sequence: first, the time is shifted backward, then the intermediate observation position is occupied, then the incoming edge and outgoing edge are unique, and finally the retrace relationship is checked. If any constraint is not met, the connection is not made. When the adjacent sequence number's subsequent position does not meet the access conditions, it is allowed to retrieve the observation position corresponding to the next sequence number as a continuation candidate position. Access to the tail of the chain is only allowed when the observation position corresponding to the next sequence number satisfies the condition that the previous position has responded, the subsequent position has responded, and the observation position corresponding to the middle sequence number has not been written with a reverse relationship. When the consistency constraint is satisfied, the corresponding candidate subsequent position is accessed to the tail of the chain and the tail position is updated. Access is stopped when there is no candidate subsequent position that satisfies the consistency constraint. The output is the action arrival sequence, which includes at least the chain position order, observation position, order type, and response occurrence time. It is written to S43 and S44 for reading. The abnormal or missing handling is as follows: if the action arrival sequence only contains the start position, it is still retained; if even the start position cannot be established, an empty action arrival sequence mark is written and entry into S43 is stopped. S43 is used to extract the thermal and humidity anomaly extension sequence from the action arrival sequence. Its mechanism is to extract the continuous succession chain from the subsequent response that has not been covered by the normal propagation of the action, so as to distinguish between the action propagation result and the subsequent extension result of the anomaly. The input quantities are the action arrival sequence, the response sequence set, and the unified position index table. The processing actions include: extracting the observation positions whose response occurrence time is later than the response occurrence time of the corresponding chain position and has not been written into the action arrival sequence from the response sequence set, and performing chain access starting from each chain tail position in the action arrival sequence, according to the same cabinet position continuity constraint, time shift constraint, and retracement closure constraint as S42. Among them, the cabinet position continuity constraint requires by default that the sequence number is adjacent, and only allows crossing one unaccessed vacancy, and does not allow crossing two vacancy consecutively; the time shift constraint requires that the response occurrence time of the subsequent observation position is later than the response occurrence time of the preceding observation position; the retracement closure constraint requires that the subsequent observation position has a retracement relationship pointing back to the previously accessed position. When the above constraints are met, the observation positions subsequently connected by the same chain tail position will form a thermal and humidity anomaly extension sequence. When the same observation position enters different thermal and humidity anomaly extension sequences at the same time, one access result is retained in a fixed order: first the conductive connection sequence, then the airflow sequence, and finally the insulation surface unfolding sequence. The remaining access results are deleted. The output is a thermal and humidity anomaly extension sequence set, which includes at least the sequence number, chain tail position, observation position, sequence type, and response occurrence time. This set is written to S44 for reading. The abnormal or missing handling is as follows: when no thermal and humidity anomaly extension sequence is formed, the action arrival sequence is retained and an empty thermal and humidity anomaly extension sequence mark is written. S44 is used to identify weak points in thermal and humidity control and generate a set of control targets. Its mechanism involves extracting the position that first breaks away from the action arrival sequence but can still receive subsequent responses from the thermal and humidity anomaly expansion sequence, using this position as the direct target for subsequent thermal and humidity control. The inputs are the set of thermal and humidity anomaly expansion sequences and the action arrival sequence. The processing actions include: performing first-position verification on each thermal and humidity anomaly expansion sequence according to the order of observation position access; firstly, retrieving the first observation position in the thermal and humidity anomaly expansion sequence that breaks away from the action arrival sequence; if at least one subsequent observation position follows this first observation position, then this first observation position is identified as a weak point in thermal and humidity control; when thermal and humidity... When the abnormal extension sequence contains only one observation point, that unique observation point is directly identified as the thermal and humidity weak point. Subsequently, the corresponding action arrival sequence, thermal and humidity abnormal extension sequence, and thermal and humidity weak point are merged and written into the same control object record. The output is the set of control objects, which includes at least the current control round number, the initial abnormal point, the control borrow action number, the action arrival sequence, the thermal and humidity abnormal extension sequence, the thermal and humidity weak point, and the observation point set reference identifier, and is written to S5 for reading. The abnormal or missing handling is as follows: when the thermal and humidity abnormal extension sequence is empty, the action arrival sequence is retained in the control object set, and the thermal and humidity weak point field is marked as empty. Through the above processing, S4 completes the transformation from the response sequence set to the regulation object set, distinguishes the action arrival sequence formed by the normal propagation of the regulation borrowing action from the thermal and humidity anomaly expansion sequence formed by the subsequent anomaly expansion, and further verifies the thermal and humidity weak points, providing direct input for the subsequent action binding and thermal and humidity regulation in S5; this processing ensures that the starting position can be replaced, the access constraint has a fixed verification order, the parallel acceptance can be uniquely resolved, and the thermal and humidity weak point verification has a clear caliber, avoiding the chain break or ambiguity in the control object generation process; In practical applications: When the action position of the regulation borrowed action is P03, and the action arrival sequence sequentially covers P03, P04, and P05, and the response sequence set subsequently shows consecutive shifted responses of P07, P08, and P09, S41 first generates candidate subsequent positions and back-pointing candidate relationships starting from P03 under three types of sequences. S42 solves the action arrival sequence from P03 to P05 based on this. S43 then extracts the thermal and humidity anomaly extension sequence from P07 to P09 from the observation positions that have never entered the action arrival sequence and whose response time is later than P05, and eliminates the parallel access of the same position in a fixed order. S44 finally determines P07 as the thermal and humidity weak position, and writes the corresponding action arrival sequence, thermal and humidity anomaly extension sequence, and thermal and humidity weak position into the regulation object set for S5 to directly execute subsequent thermal and humidity regulation.

[0020] S5. Based on the set of adjustment objects, apply the subsequent adjustment actions to the locations of each thermal and humidity weak point and the coverage locations of each thermal and humidity abnormality expansion sequence, perform thermal and humidity state adjustment on the high-voltage switchgear, and after execution, obtain the temperature data, humidity data, partial discharge data, current data and voltage data of the corresponding locations again, perform verification in the same order comparison method as S2, and output the results of the current adjustment round. In this embodiment, S5 is used to perform subsequent thermal and humidity regulation based on the set of regulation objects, and to review the regulation results to generate the results of the current regulation round. Its processing principle is to first generate a unique subsequent action table based on the location of the thermal and humidity weak point and the coverage position of the thermal and humidity anomaly extension sequence, then execute the subsequent actions item by item according to the writing order in the subsequent action table and record the data before and after the action execution, and finally re-determine whether each position still enters the initial abnormal position according to the same sequence comparison caliber as S2, thereby distinguishing between regulation completion positions and continued regulation positions. This implementation process includes the following steps: S51 is used to generate the subsequent action table. Its working mechanism is to convert the locations of thermal and moisture weak points and the locations covered by thermal and moisture anomaly expansion sequences in the set of regulated objects into directly executable subsequent action binding results. The input quantities are the set of regulated objects, the set of currently allowed regulated actions, and the unified location index table. The processing actions include: first, extracting the locations of each thermal and moisture weak point and the locations covered by each thermal and moisture anomaly expansion sequence from the set of regulated objects; performing sequential sorting on the extracted results, arranging the locations of thermal and moisture weak points first and the locations covered by thermal and moisture anomaly expansion sequences last; and then writing the same type of locations sequentially according to the conductive connection order, the airflow passage order, and the insulation surface unfolding order. Then, subsequent actions corresponding to each position are retrieved from the current set of allowed adjustment actions. Priority is given to actions whose action position matches the location of the thermal and humidity weak point and whose execution status is allowed. If no action is retrieved, actions whose action position matches the first position of the thermal and humidity anomaly extension sequence and whose execution status is allowed are retrieved. If no action is retrieved, actions whose action position matches the first position of the thermal and humidity anomaly extension sequence and whose execution status is allowed are retrieved according to the writing order of the positions covered by the thermal and humidity anomaly extension sequence. When there are multiple candidate subsequent actions at the same position, the first action is retained according to the writing order of the current set of allowed adjustment actions. The output is a subsequent action table, which includes at least the current adjustment round number, position number, position type, subsequent action number, action position, and writing order, and is written to S52 for reading. The handling of anomalies or missing actions is as follows: if no allowed subsequent action is retrieved at a certain position, the position is retained and an empty action mark is written in the subsequent action field, and a mark indicating that manual handling is pending is also written. When the same position appears repeatedly, only the first written record is retained. S52 is used to perform thermal and humidity control adjustments and generate a verification record set. Its working mechanism is to execute subsequent actions one by one in a fixed order according to the subsequent action table, and write the data before and after the action execution into the same verification record. The input quantities are the subsequent action table, the position record set, and the current control cycle number. The processing actions include: reading subsequent actions one by one in the writing order of the subsequent action table, and not writing the next subsequent action before the previous subsequent action reaches the end state and is written back; for each subsequent action, before writing, first extract the action execution record before the corresponding position number in the position record set, then perform thermal and humidity control adjustments, and after the subsequent action reaches the end state and is written back, extract the action execution record after the corresponding position number. Both the pre-action and post-action records include at least temperature, humidity, partial discharge, current, and voltage data. These are then merged and written according to the action sequence and cabinet location, with the pre-action and post-action records for the same subsequent action corresponding to the same location written into the same review record item. The output is a review record set, which includes at least the current adjustment cycle number, subsequent action number, cabinet location number, time before action execution, time after action execution, temperature data, humidity data, partial discharge data, current data, and voltage data, and is written to S53 for reading. Abnormal or missing data handling is as follows: if the subsequent action field has an empty action marker, the thermal and humidity adjustment is not performed; only a "not executed" marker is written to that location. If no record is obtained for the corresponding location after action execution, the post-action field is marked as a missing field, and the review record item is retained. S53 is used to generate the current adjustment round result based on the review record set. Its working mechanism is to re-enter each adjusted position into the same order comparison process as S2 to determine whether it has re-entered the initial abnormal position. The input quantities are the review record set, the unified position index table, and the conductive connection sequence, airflow sequence, and insulation surface unfolding sequence in S2. The processing actions include: firstly, extracting the temperature data, humidity data, and partial discharge data of the corresponding position according to the cabinet position number and the time after the action is executed based on the review record set; then, re-forming the conductive order column, airflow order column, and surface order column according to the same conductive connection sequence, airflow sequence, and insulation surface unfolding sequence as S2; and re-executing the comparison of the order of temperature change, humidity change, and partial discharge change according to the same rules as S2. Then, following the same starting change position extraction rules and cross-correspondence rules as S2, it is re-evaluated whether each position has entered the initial abnormal position; positions that no longer enter the initial abnormal position are recorded as adjustment completion positions, and positions that still enter the initial abnormal position are recorded as continued adjustment positions; finally, the adjustment completion positions, continued adjustment positions, and their corresponding subsequent actions are merged and written into the current adjustment round result; the output is the current adjustment round result, which includes at least the current adjustment round number, the adjustment completion position set, the continued adjustment position set, the corresponding subsequent actions, and whether to enter the next round control flag, and is written back to the round result storage unit for the next round to read; the abnormal or missing handling is as follows: when a position contains a missing field flag in the review record set, the missing field does not participate in the re-ranking comparison, and the position is directly written with the review incomplete flag; when all positions do not enter the initial abnormal position, the whether to enter the next round control flag is written as no; Through the above processing, S5 completes the binding of subsequent actions, the execution of heat and humidity regulation, and the verification of regulation results, and obtains the result of the current regulation round. This processing ensures that the binding of subsequent actions has a unique caliber, the execution of subsequent actions does not overlap, the verification judgment is consistent with S2, and the result can be directly inherited to the next round of control. In practical applications: When the weak point of heat and humidity in the set of regulated objects is P07, and the positions covered by the heat and humidity anomaly extension sequence are P08 and P09, S51 first writes P07 first, followed by P08 and P09. Then, it sequentially retrieves subsequent actions from the current set of allowed regulated actions whose positions are consistent with P07, P08, and P09 and whose execution status is allowed to be put into operation, forming a subsequent action table. S52 then executes the subsequent actions one by one according to the writing order in the subsequent action table, and merges the temperature data, humidity data, partial discharge data, current data, and voltage data before and after each action into the verification record set. S53 then re-determines whether P07, P08, and P09 still enter the initial abnormal position according to the same order comparison rule as S2. If P07 and P08 no longer enter the initial abnormal position but P09 still enters the initial abnormal position, then P07 and P08 are recorded as regulated completion positions, P09 is recorded as a continued regulated position, and the corresponding subsequent actions are written together into the current regulated round result.

[0021] The working principle of this scheme is as follows: First, the temperature, humidity, partial discharge, current, voltage, and other data collected by the high-voltage switchgear in the same control cycle are organized into a unified location record set according to the collection time and position inside the switchgear. Then, the changes at each position are compared along the conductive connection sequence, airflow sequence, and insulation surface unfolding sequence to identify the position where the anomaly first occurred and was not previously addressed, which is designated as the initial anomaly position. A regulation borrowing action that can be directly initiated is selected from the currently permitted actions. Subsequently, a restricted activation is performed on this regulation borrowing action, and the changes in multiple physical quantities at each observation position before and after activation are read to solve the regulation... The actual propagation sequence of the borrowed action within the cabinet is used to form a response sequence. Then, based on the response sequence, it is determined which positions belong to the range normally reached by the borrowed action and which positions belong to the abnormal following range that continues to expand after the action. The starting position of the abnormal following range is determined as the thermal and humidity weak point. Finally, the subsequent actions are directly applied to the thermal and humidity weak point and the position covered by the thermal and humidity abnormal expansion sequence. After the action is executed, it is re-verified according to the same sequence comparison rules as before, so as to determine which positions have been adjusted and which positions still need to be adjusted, forming the result of the current adjustment round for use in the next round. For example, in the traction power supply room of rail transit or the power distribution room of an industrial plant, when a high-voltage switchgear is running continuously for a long time, a certain compartment may first experience a local temperature rise, followed by changes in humidity or an increase in partial discharge. Traditional methods often simply activate the fan or heater as soon as a value at a certain measuring point rises. However, this solution will first compile the data of the compartment and related locations in the surrounding area to determine whether the anomaly is propagating along conductive connections, spreading along air ducts, or spreading along the insulation surface. Then, it will select a currently permissible adjustment action for a limited initial implementation. For example, after activating the fan once, the system will compare the changes in temperature, current, voltage, humidity, and partial discharge at each observation point before and after the fan operation. It will determine which locations are normally affected by the fan and which locations, although showing changes later, are not directly affected by the fan but are the result of the anomaly continuing to spread outward. In this way, the truly vulnerable points of heat and humidity that need to be addressed can be identified, and subsequent actions can be applied more specifically to these locations, avoiding simply suppressing surface phenomena while ignoring the real hidden dangers.

6. The method for coordinated regulation of thermal and humidity conditions of a high-voltage switchgear according to claim 5, characterized in that: S3 also includes: S33. For the candidate propagation chain set, according to the fixed field order of temperature change direction, current change direction, voltage change direction, humidity change direction and partial discharge change direction, perform item-by-item consistency check and conflict resolution on the multi-field response of the same observation position. When the previous field has formed a chain position and the next field has a reverse retracement, delete the chain position corresponding to the next field. When the previous field has not formed a chain position and the next field forms a continuous connection, retain the chain position corresponding to the next field and write the retention result back to the candidate propagation chain set, and output the consistent response chain set. S34. Based on the consistent response chain set, perform double-order expansion according to the time sequence from the start time of the action to the end time of the action and the chain position sequence. Record the time when each observation position first enters the consistent response chain set as the response occurrence time, and write it into each observation position according to the response occurrence time, chain position sequence and cabinet position sequence, and output the response sequence set.

7. The method for coordinated regulation of thermal and humidity conditions of a high-voltage switchgear according to claim 6, characterized in that: S4 includes: S41. Based on the response sequence set, with the position of the adjustment borrowing action as the starting position, perform forward timing retrieval on each observation position according to the conductive connection sequence, airflow sequence, and insulation surface unfolding sequence, extract candidate subsequent positions whose response occurrence time is later than the starting position and whose positions in the cabinet are continuous, and simultaneously extract the reverse candidate relationship of each candidate subsequent position pointing back to the previous position, and output the forward candidate table and the back-pointing candidate table. S42. Solve the consistency constraints for each candidate position by using the forward candidate list and the back-pointing candidate list. The consistency constraints include shifting the response occurrence time sequentially from the previous position to the next position, retaining only one incoming edge and one outgoing edge for the same observation position, ensuring that there are no intermediate observation positions of the same order that are not connected to the chain between the previous and the next positions, and pointing back to the previous position that has been connected to the chain. When the consistency constraints are satisfied, the corresponding candidate position is connected to the tail of the chain and the tail position is updated. When there are no candidate positions that satisfy the consistency constraints, the connection is stopped and the action arrival sequence is output.

8. The method for coordinated regulation of thermal and humidity conditions of a high-voltage switchgear according to claim 7, characterized in that: S4 also includes: S43. Based on the action arrival sequence, extract the observation bits whose response time is later than the corresponding chain position response time and have not been written into the action arrival sequence from the response sequence set. Perform chain access according to the same cabinet position continuity constraint, time shift constraint and back finger closure constraint as S42. Connect the observation bits subsequently received by the same chain tail position into a thermal and humidity anomaly extension sequence. When the same observation bit enters different thermal and humidity anomaly extension sequences at the same time, perform fixed sequence resolution according to the conductive connection sequence, airflow sequence and insulation surface unfolding sequence, and output thermal and humidity anomaly extension sequence set. S44. Perform first-position verification on each thermal humidity anomaly extension sequence through the thermal humidity anomaly extension sequence set, determine the first observation position in each thermal humidity anomaly extension sequence that is disconnected from the action arrival sequence and is followed by at least one subsequent observation position as the thermal humidity weak position, and merge the corresponding action arrival sequence, thermal humidity anomaly extension sequence and thermal humidity weak position into the same control object record, and output the regulation object set.

9. The method for coordinated regulation of thermal and humidity conditions of a high-voltage switchgear according to claim 8, characterized in that: S5 includes: S51. Based on the set of adjustment objects, perform sequential sorting of the locations of each thermal and moisture weak point and the coverage locations of each thermal and moisture abnormality expansion sequence. Arrange the locations of the thermal and moisture weak points first, and arrange the coverage locations of the thermal and moisture abnormality expansion sequence last. Write the same type of locations in order of conductive connection, airflow passage, and insulation surface unfolding. Bind each location to the corresponding subsequent action execution location in the current set of allowed adjustment actions, and output the subsequent action table. S52. Based on the subsequent action table, perform heat and humidity adjustment for each subsequent action in the order of writing in the subsequent action table, and obtain the temperature data, humidity data, partial discharge data, current data and voltage data of the corresponding location after each subsequent action is executed. Combine the records before and after each subsequent action is executed according to the action order and the location in the cabinet, and output the verification record set. S53. Based on the verification record set, and following the same conductive connection sequence, airflow sequence, and insulation surface unfolding sequence as in S2, re-perform the sequential comparison of temperature change, humidity change, and partial discharge change at each corresponding position. Record the position that no longer enters the initial abnormal position as the adjustment completion position, and record the position that still enters the initial abnormal position as the adjustment continuation position. Combine and write the adjustment completion position, adjustment continuation position, and their corresponding subsequent actions, and output the result of the current adjustment round.
