Description

Technical Field

[0001] This invention relates to the field of circuit breaker control technology, specifically to a dynamic performance optimization control method and system for primary and secondary integrated pole-mounted circuit breakers. Background Technology

[0002] In traditional power distribution systems, pole-mounted circuit breakers, integrating primary and secondary circuits, serve as electrical protection devices, primarily used to isolate electrical faults and prevent equipment damage. However, with the continuous increase in grid load and the increasing complexity of power distribution systems, traditional circuit breakers often face problems such as performance degradation, overheating, and insulation aging during long-term operation, rendering them unable to operate effectively under high loads or complex conditions. While some circuit breakers are equipped with simple monitoring sensors, these devices often cannot comprehensively and in real-time monitor the electrical, mechanical, and insulation status of the circuit breaker, lacking flexible adjustment and optimization capabilities. For example, the sampling frequencies and timestamps of current and displacement sensors may be inconsistent (current sampling period is 500ms, displacement sampling may be 100ms), resulting in asynchronous sensing and monitoring information in the time dimension. This asynchronicity causes phase shifts in the integration of operating status data, vacuum interrupter contact displacement data, and pole insulation performance data, thus affecting the accuracy of performance evaluation.

[0003] In addition, existing technologies mostly rely on manual intervention and regular inspections for equipment maintenance, which can easily overlook some potential hidden faults, leading to frequent equipment failures or excessive downtime, affecting the stability and reliability of the power distribution system. Summary of the Invention

[0004] This application provides a dynamic performance optimization control method and system for primary and secondary integrated pole-mounted circuit breakers, which solves the technical problem that traditional circuit breakers lack comprehensive real-time monitoring and intelligent control, making it difficult to accurately evaluate and optimize equipment performance under complex operating conditions.

[0013] This application provides a dynamic performance optimization control method and system for primary and secondary integrated pole-mounted circuit breakers, which solves the technical problem that traditional circuit breakers lack comprehensive real-time monitoring and intelligent control, making it difficult to accurately evaluate and optimize equipment performance under complex operating conditions.

Obviously, the described embodiments are only a part of the embodiments of this application, and not all of them. All other embodiments obtained by those skilled in the art based on the embodiments of this application without creative effort are within the scope of protection of this application.

It should be understood that such data can be interchanged where appropriate so that the embodiments of this application described herein can be implemented in orders other than those illustrated or described herein. Furthermore, the terms "comprising" and "having," and any variations thereof, are intended to cover non-exclusive inclusion; for example, a process, method, system, product, or server that includes a series of steps or units is not necessarily limited to those steps or units explicitly listed, but may include other steps or modules not explicitly listed or inherent to such processes, methods, products, or devices.

[0016] Example 1, as Figure 1 As shown, this application provides a dynamic performance optimization control method for a primary and secondary integrated pole-mounted circuit breaker, the method comprising:

[0017] P10: Activate the integrated sensor to monitor the circuit breaker in real time and obtain sensing and monitoring information.

[0018] Furthermore, step P10 in this embodiment of the application also includes:

[0019] P11: The circuit breaker is monitored in real time using the current sensor, dual voltage sensor, and temperature sensor in the integrated sensor to obtain operating status data; P12: The position of the vacuum interrupter contact of the circuit breaker is monitored in real time using the displacement sensor in the integrated sensor to obtain vacuum interrupter contact displacement data; P13: The insulation performance of the circuit breaker's pole insulation is monitored in real time using the insulation detection sensor in the integrated sensor to obtain pole insulation performance data; P14: The operating status data, the vacuum interrupter contact displacement data, and the pole insulation performance data constitute the sensing and monitoring information.

[0020] It should be understood that by activating multiple types of sensing elements in the integrated sensor, comprehensive data on the electrical, mechanical, and insulation status of the circuit breaker can be acquired, forming high-dimensional sensing and monitoring information, which provides data support for subsequent performance evaluation and optimized control.

[0021] First, the current sensor, dual voltage sensor, and temperature sensor configured in the integrated sensor are activated to collect real-time data on the circuit breaker's operating current, voltage status, and temperature of key components. The current sensor uses Hall effect or fiber optic current transformers to accurately detect dynamic changes in the circuit breaker's load side and fault current. The dual voltage sensors are deployed on the primary side and secondary control module of the circuit breaker, respectively, employing high-precision voltage sampling units to achieve synchronous monitoring of input and output voltages, facilitating the identification of operational anomalies such as voltage sags and overvoltages. The temperature sensors are distributed on the circuit breaker busbars, contact connection points, and the exterior of the arc-extinguishing chamber housing to monitor the thermal status of each component in real time, assessing the equipment's thermal stability and overload operation risk. All of the above data is collectively referred to as operating status data, and is continuously uploaded to the edge computing module or remote master station system via field terminals at a fixed sampling period (e.g., 500ms to 1s).

[0022] Next, the displacement sensors deployed in the integrated sensor are activated to continuously monitor the position of the contacts in the vacuum interrupter inside the circuit breaker. These displacement sensors can be grating-coded, Hall effect linear, or laser reflective, and are installed at the linkage structure between the mechanical operating mechanism and the moving contacts of the circuit breaker. They are used to accurately collect the contact opening distance, displacement velocity, and end-point position during closing and opening. This data reflects the mechanical response state of the interrupter and the degree of contact wear in real time, helping to identify potential faults such as sluggish operating mechanism, excessive wear, or mechanical jamming. The collected contact movement trajectory data is recorded as vacuum interrupter contact displacement data and can be synchronously uploaded to the equipment status sensing module for dynamic modeling.

[0023] Next, the insulation detection sensors configured in the integrated sensor are activated to continuously monitor the insulation performance of the circuit breaker poles. These insulation detection sensors may include power frequency leakage current detection devices, dielectric loss detection modules, or surface conductivity monitoring devices, installed on the circuit breaker pole housing and grounding connection points. They can capture changes in the dielectric properties of the poles under different environmental conditions (such as humidity, high temperature, and pollution). This monitoring can effectively identify the risk of insulation performance degradation due to aging, moisture, or contamination, providing a basis for taking early maintenance or replacement measures. The acquired insulation status parameters constitute the pole insulation performance data and are used as key health factors in the calculation of the equipment performance evaluation model.

[0024] Finally, the operational status data, vacuum interrupter contact displacement data, and pole insulation performance data obtained in the above steps are fused in multiple dimensions to form a unified and structured sensing and monitoring information. This sensing and monitoring information has strong time synchronization, a wide range of data sources, and comprehensive diagnostic dimensions, covering key parameters in the circuit breaker operation process. Through the above design, high-precision real-time monitoring of electrical performance, mechanical action characteristics, and insulation status can be achieved without changing the existing circuit breaker structure.

[0025] Furthermore, step P11 in the embodiments of this application also includes:

[0026] P11-1: The three-phase current and zero-sequence current are simultaneously measured by the current sensor; P11-2: The first voltage is monitored by the first voltage sensor in the dual voltage sensor system, wherein the first voltage sensor is located on the load side; P11-3: The second voltage is monitored by the second voltage sensor in the dual voltage sensor system, wherein the first voltage sensor is located on the power supply side; P11-4: Temperature data is monitored by the temperature sensor in the dual voltage sensor system; P11-5: The three-phase current, the zero-sequence current, the first voltage, the second voltage, and the temperature data constitute the operating status data.

[0027] Optionally, the specific process of acquiring operating status data through the current sensor and dual voltage sensors in the integrated sensor can be further refined to ensure the comprehensiveness and accuracy of the monitoring data, thereby providing a reliable basis for subsequent performance evaluation.

[0028] First, the built-in current sensors synchronously measure the three-phase current and zero-sequence current. The three-phase current reflects the current load condition of the circuit breaker, identifying operational anomalies such as current overload, imbalance, or sudden changes. The zero-sequence current detects whether there are grounding faults or asymmetrical faults in the system, playing a crucial role in ensuring the accuracy of the system's protection actions. Current sampling is performed continuously at fixed intervals to ensure the acquisition of the dynamic changes in the current signal.

[0029] Subsequently, voltage signals across the circuit breaker are acquired using dual voltage sensors deployed in the integrated sensor. The first voltage sensor is located on the load side to monitor the output voltage of the circuit breaker; this data reflects power supply quality, load response, and end-voltage stability. The second voltage sensor is located on the power supply side to acquire the upstream system supply voltage. By comparing this voltage with the first voltage sensor, real-time analysis of internal voltage drop, voltage disturbance conduction paths, and potential internal contact anomalies within the circuit breaker can be performed, aiding in fault location. The simultaneous acquisition of the first and second voltage sensors facilitates the construction of a state model of the electrical response relationship between the circuit breaker's internal and external components.

[0030] Meanwhile, temperature data during equipment operation is collected using temperature sensors integrated into the sensor unit. These sensors are typically installed in areas of high heat concentration within the circuit breaker body, such as conductive connection terminals, arc-extinguishing chamber housings, or insulating support joints, to monitor the thermal stability of critical components. Temperature data not only reveals the equipment's thermal load status but can also be used to identify abnormal temperature rises caused by poor contact, overload operation, or long-term aging.

[0031] Finally, the collected three-phase current, zero-sequence current, first voltage, second voltage, and temperature data are uniformly organized to form structured operating status data, which serves as an important component in constructing the circuit breaker's sensing and monitoring information. This operating status data set features high sampling granularity, comprehensive parameter coverage, and strong dynamic correlation, supporting not only subsequent dynamic performance index calculations but also providing a solid data basis for predictive maintenance, fault prediction, and intelligent control strategies for circuit breakers.

[0032] Furthermore, before the three-phase current, the zero-sequence current, the first voltage, the second voltage, and the temperature data are combined to form the operating status data, this embodiment of the application further includes step P11-5a, which further includes:

[0033] P11-51a: Calculate the housing-to-ground voltage based on the first voltage and the second voltage; P11-52a: Issue a safety anomaly signal when the housing-to-ground voltage is not at a predetermined threshold.

[0034] Specifically, to enhance the online monitoring capability for the safe operation of pole-mounted circuit breakers, before the three-phase current, zero-sequence current, first voltage, second voltage, and temperature data are aggregated into operating status data, a step for grounding status identification and fault early warning can be introduced to achieve real-time assessment and anomaly detection of the grounding status of the circuit breaker casing.

[0035] Specifically, the circuit breaker casing-to-ground voltage is first calculated using the difference between the first and second voltage data points obtained from the electrical reference points. Specifically, the casing-to-ground voltage can be calculated by measuring the voltage difference between the load side and the power supply side, and then converting it using a potential difference model of the equipment body to ground, thereby deriving the actual potential deviation between the circuit breaker casing and ground. This calculation process can be automatically completed in the equipment-side edge processing unit or remote monitoring system based on a preset algorithm, without the need for additional grounding voltage sensors. The casing-to-ground voltage is an important parameter for evaluating the insulation performance and grounding safety of the circuit breaker. Under normal circumstances, the casing-to-ground voltage should be maintained within a safe range, and its value reflects the integrity of the circuit breaker's insulation system and the reliability of the grounding system.

[0036] Next, if the calculated voltage of the circuit breaker casing to ground is not within the predetermined threshold range (i.e., its value is higher or lower than the set upper or lower limit), it indicates that the circuit breaker casing has abnormal operating conditions such as poor grounding, insulation damage, or induced charge accumulation. At this time, the system will immediately generate a safety anomaly signal. This anomaly signal can be reported to the main station in real time through the communication module, or it can be linked to the on-site alarm device to issue an audible and visual alarm to prompt maintenance personnel to intervene. This mechanism can issue an effective early warning before the equipment causes a more serious insulation accident or a risk of electric shock. The predetermined threshold is a voltage range pre-set according to the circuit breaker's design standards and safe operation requirements. When the voltage of the circuit breaker casing to ground exceeds this range, it may indicate that the circuit breaker's insulation system has a fault or that the grounding system is abnormal.

[0037] By adding steps, not only can the operating status data of the circuit breaker be comprehensively monitored, but also key safety parameters can be evaluated and warned in real time, further enhancing the reliability and safety of the circuit breaker operating status monitoring system.

[0038] Furthermore, after the operating status data, the vacuum interrupter contact displacement data, and the pole insulation performance data constitute the sensing and monitoring information, this embodiment of the application further includes step P14a, which further includes:

[0039] P14-1a: Obtain the opening and closing operation records of the circuit breaker; P14-2a: Analyze the opening and closing operation records by retrieving predetermined opening and closing operation indicators to obtain opening and closing operation data; P14-3a: Add the opening and closing operation data to the sensing and monitoring information; wherein, the predetermined opening and closing operation indicators include at least opening and closing speed, synchronicity, and rebound amplitude.

[0040] In one possible embodiment of this application, to further enhance the comprehensive monitoring and evaluation of the status of the pole-mounted circuit breaker, step P14a is introduced to supplement the relevant data of the circuit breaker's opening and closing operations, so as to ensure that the sensing and monitoring information not only covers the electrical, mechanical and insulation performance data of the equipment, but also includes the data of the equipment's operating performance, thereby enabling a more comprehensive evaluation of the dynamic performance of the circuit breaker.

[0041] First, the circuit breaker's opening and closing operation records are acquired. These records detail each opening or closing operation, including the time of the operation, the operation type (e.g., opening or closing), the duration of the operation, and the specific time of contact actuation. These operation records can be acquired and stored in real-time through the circuit breaker's own operation recording module or a remote control system, and possess high time accuracy and reliability.

[0042] Next, predetermined opening and closing operation indicators are retrieved, and the acquired opening and closing operation records are analyzed. These predetermined indicators include at least opening and closing speed, synchronicity, and rebound amplitude. Opening and closing speed refers to the speed at which the circuit breaker contacts move from open to closed or vice versa. Excessive opening speed may cause mechanical shock, while excessively slow speed may affect the circuit breaker's breaking capacity. Closing speed directly affects the circuit breaker's closing performance and synchronicity. Synchronicity refers to the degree to which the three-phase contacts simultaneously contact during the closing operation. Good synchronicity reduces current surges during closing and improves power system stability. Rebound amplitude refers to the magnitude of contact rebound during the closing process due to mechanical shock and other factors. Excessive rebound amplitude may lead to contact damage or poor contact. By retrieving these predetermined indicators and analyzing the opening and closing operation records, opening and closing operation data can be obtained. This data quantifies the circuit breaker's performance during opening and closing operations, providing an important basis for subsequent performance evaluation.

[0043] Finally, the analyzed opening and closing operation data are added to the sensing and monitoring information. The sensing and monitoring information already includes operating status data, vacuum interrupter contact displacement data, and pole insulation performance data; adding the opening and closing operation data further enriches the content of the sensing and monitoring information. In this way, the sensing and monitoring information can reflect not only the static operating status of the circuit breaker but also its performance during dynamic operation. This data will serve as important input for subsequent performance evaluation mechanisms, providing more comprehensive data support for the calculation of dynamic performance indices and the retrieval of optimization strategies, thereby achieving precise and optimized control of the primary and secondary integrated pole-mounted circuit breaker.

[0044] P20: The sensed and monitored information is evaluated and analyzed according to the performance evaluation mechanism to obtain a dynamic performance index. The performance evaluation mechanism includes a breaking capacity evaluation plan, an insulation performance evaluation plan, and a mechanical characteristic evaluation plan.

[0045] Furthermore, step P20 in this embodiment of the application also includes:

[0046] P21: Obtain the predetermined maximum short-circuit current of the circuit breaker; P22: Perform a coordinated evaluation of the predetermined maximum short-circuit current, the three-phase current, and the zero-sequence current according to the breaking capacity assessment plan to obtain an initial breaking capacity index; P23: Calibrate the initial breaking capacity index in conjunction with the temperature data to obtain a breaking capacity index; P24: Perform a coordinated evaluation of the first voltage, the second voltage, and the pole insulation performance data according to the insulation performance assessment plan to obtain an insulation performance index; P25: Perform a coordinated evaluation of the vacuum interrupter contact displacement data and the opening and closing operation data according to the mechanical characteristic assessment plan to obtain a mechanical performance index; P26: Perform a coefficient of variation weighted calculation on the breaking capacity index, the insulation performance index, and the mechanical performance index to obtain the dynamic performance index.

[0047] It should be understood that a comprehensive evaluation and analysis of the sensing and monitoring information is conducted according to the performance evaluation mechanism to obtain a dynamic performance index. This performance evaluation mechanism covers breaking capacity evaluation plans, insulation performance evaluation plans, and mechanical characteristic evaluation plans to ensure that the performance of the circuit breaker is quantitatively evaluated from multiple key dimensions.

[0048] First, obtain the circuit breaker's predetermined maximum short-circuit current, which is the theoretical maximum short-circuit current value determined based on the circuit breaker's design specifications and the installation environment. This parameter provides a basic reference value for assessing breaking capacity and is usually provided by the circuit breaker manufacturer or calculated based on the actual load and grid characteristics.

[0049] Next, according to the breaking capacity assessment plan, a coordinated assessment is performed on the predetermined maximum short-circuit current and the three-phase current and zero-sequence current from the sensing and monitoring information. This assessment process aims to compare the difference between the predetermined maximum short-circuit current and the real-time current state to check whether the current load may exceed the circuit breaker's breaking capacity. Through this process, an initial breaking capacity index can be obtained, which reflects the adequacy of the circuit breaker's current breaking capacity and can be assessed by comparing the breaking capacity requirement with the actual load.

[0050] Then, temperature data is incorporated into the calibration of the initial breaking capacity index. Temperature changes directly affect the electrical and mechanical performance of circuit breakers, especially due to heat accumulation caused by overload or prolonged operation. Therefore, temperature changes affect breaking capacity; excessively high temperatures may lead to increased contact losses or reduced arc-extinguishing performance. The breaking capacity index needs to be appropriately adjusted based on temperature data. For example, a temperature influence coefficient can be calculated based on the actual temperature and a reasonable temperature threshold, and then the initial breaking capacity index can be calibrated using this coefficient to obtain an accurate breaking capacity index.

[0051] Next, according to the insulation performance assessment plan, the insulation performance data of the first voltage, the second voltage, and the pole were jointly assessed. Insulation performance is the foundation of the safe operation of circuit breakers. By assessing voltage data and insulation performance data, the insulation performance of circuit breakers can be quantified. For example, the insulation status of circuit breakers under different voltage conditions can be assessed, with a focus on the downward trend of insulation performance, to derive an insulation performance index. This index reflects the insulation reliability and potential risks of the circuit breaker.

[0052] Subsequently, according to the mechanical characteristic assessment plan, the contact displacement data of the vacuum interrupter and the opening and closing operation data were jointly evaluated. Mechanical characteristics directly affect the operating performance and reliability of the circuit breaker. By evaluating the contact displacement and opening and closing operation data, the mechanical performance of the circuit breaker can be quantified. This assessment mainly focuses on the operational reliability of the circuit breaker's mechanical components, such as contact position, breaking speed, and synchronicity, checking for abnormalities such as jamming, wear, or rebound in the mechanical structure, and thus deriving a mechanical performance index, which reflects the mechanical response capability and reliability of the circuit breaker.

[0053] Finally, the previously obtained breaking capacity index, insulation performance index, and mechanical performance index are weighted by the coefficient of variation to calculate a comprehensive dynamic performance index. This index, through weighted calculation, comprehensively considers the variability and weight of each performance index, forming a quantitative indicator that comprehensively assesses the current performance status of the circuit breaker. The coefficient of variation weighted calculation effectively measures the stability and reliability of equipment performance, ultimately yielding a dynamic performance index that comprehensively reflects the overall operational health of the circuit breaker. This dynamic performance index can provide data support for subsequent optimized control and help predict equipment maintenance cycles and potential failure risks.

[0054] Furthermore, after calculating the dynamic performance index by weighting the coefficient of variation of the breaking capacity index, the insulation performance index, and the mechanical performance index, this embodiment of the application further includes step P26a, which further includes:

[0055] P26-1a: Obtain the historical operation record of the circuit breaker, wherein the historical operation record includes a first maintenance record; P26-2a: Analyze the first maintenance record to obtain a first performance loss coefficient, and sum them to obtain a historical loss coefficient; P26-3a: Obtain the historical operating time based on the historical operation record, and obtain a performance correction factor in conjunction with the historical loss coefficient; P26-4a: Correct and adjust the dynamic performance index based on the performance correction factor.

[0056] Optionally, the calculation process of the dynamic performance index can be further extended, and dynamic corrections can be made in combination with historical operating records to more accurately reflect the actual performance changes of the circuit breaker in different operating cycles, ensuring that the assessment is more in line with the long-term operating conditions of the equipment.

[0057] Specifically, the first step is to obtain the historical operating records of the circuit breakers. These records contain long-term operational data, especially the first maintenance inspection records, which are the initial and periodic maintenance records of the circuit breakers. The first maintenance inspection records detail the inspection results, equipment performance status, maintenance items, and replaced parts during each maintenance process. This record is a key data source for assessing the long-term operational performance of the equipment, providing information on the equipment's past fault history, maintenance status, and performance change trends.

[0058] Next, the first maintenance record is analyzed. Through in-depth analysis of the data in the maintenance record, the first performance loss coefficient is derived. This coefficient is a quantitative indicator of the performance loss caused by factors such as faults, wear, or aging during the equipment's historical operation. By statistically analyzing and calculating the performance degradation that occurred during each maintenance (such as contact wear, arc-extinguishing chamber degradation, etc.), a basis for correcting subsequent evaluation models can be provided. All performance loss coefficients are summed to obtain the historical loss coefficient, which reflects the cumulative effect of the overall circuit breaker equipment performance decline due to historical factors.

[0059] Then, the historical operating time of the circuit breaker is obtained based on historical operating records. Historical operating time refers to the cumulative operating time of the circuit breaker since it was put into use; this duration can be determined through the equipment's operating logs or cumulative working hours. By co-analyzing the historical operating time with the historical loss coefficient, a performance correction factor is obtained. The performance correction factor reflects the cumulative changes in equipment performance over time and its tendency to degrade over time; this factor helps quantify the performance loss caused by increased equipment usage time.

[0060] Finally, the dynamic performance index is adjusted based on a performance correction factor. The dynamic performance index is a comprehensive performance indicator calculated using a coefficient of variation weighting, but this indicator is based solely on current monitoring data. By introducing a performance correction factor, historical performance losses and aging conditions of the circuit breaker can be taken into account, allowing for more precise adjustments to the dynamic performance index. The corrected dynamic performance index more comprehensively reflects the actual performance status of the circuit breaker, avoiding over-reliance on data from a single point in time, thereby improving the reliability of equipment management and maintenance.

[0061] P30: Based on the dynamic performance index, a predetermined optimization strategy is invoked to optimize the control of the primary and secondary fusion columns of the circuit breaker.

[0062] Furthermore, step P30 in this embodiment of the application also includes:

[0063] P31: When the dynamic performance index does not meet the predetermined index limit, determine whether the breaking capacity index has reached the first index limit; P32: If not, invoke the dual-tower heat dissipation scheme in the predetermined optimization strategy to control the heat dissipation of the circuit breaker, wherein the dual-tower heat dissipation scheme includes pre-cooling the circuit breaker by closely attaching the semiconductor cooling chip to the heat sink and drilling holes in the connecting copper busbar to concentrate the cooling effect of the circuit breaker; P33: If it has reached the limit, determine whether the insulation performance index has reached the second index limit, including:

[0064] P33-1: If not achieved, retrieve the pole insulation scheme from the predetermined optimization strategy to perform pole insulation encapsulation on the circuit breaker. The pole insulation scheme refers to casting the arc-extinguishing chamber, conductive rod, and integrated sensor of the circuit breaker into a single unit using epoxy resin. P33-2: If achieved, determine whether the mechanical performance index reaches the third index limit, including:

[0065] P33-21: If the target is not met, the oil buffer scheme in the predetermined optimization strategy is invoked to perform vibration reduction control on the circuit breaker. The oil buffer scheme refers to using a hydraulic buffer instead of a rubber pad to control opening and closing. P33-22: If the target is met, the dual-enhancement scheme in the predetermined optimization strategy is invoked to perform performance enhancement control on the circuit breaker. The dual-enhancement scheme includes a first enhancement scheme and a second enhancement scheme. The first enhancement scheme refers to increasing the control voltage of the circuit breaker, and the second enhancement scheme refers to replacing the press-fit IGBT chip with a soldered IGBT chip.

[0066] Specifically, based on the calculated dynamic performance index, a predetermined optimization strategy is retrieved to optimize the control of the primary and secondary fusion pole of the pole-mounted circuit breaker, ensuring that the equipment maintains optimal performance and safety under different operating conditions. This optimization process involves progressively determining whether each performance indicator reaches a predetermined limit, thereby selecting the appropriate control strategy.

[0067] First, when the dynamic performance index fails to meet the predetermined index limit, it is necessary to further determine whether the breaking capacity index has reached the first index limit. The first index limit is a breaking capacity threshold preset according to the circuit breaker's design standards and operating requirements, used to determine whether the circuit breaker needs heat dissipation optimization. The dynamic performance index is an indicator that comprehensively evaluates the circuit breaker's performance, while the breaking capacity index focuses on the circuit breaker's performance in terms of breaking current. If the breaking capacity index fails to reach the first index limit, it indicates that the circuit breaker may not be able to effectively break circuits under high load or short-circuit conditions, posing a safety hazard.

[0068] At this point, the dual-tower heat dissipation scheme from the predetermined optimization strategy is invoked to control the heat dissipation of the circuit breaker. This heat dissipation scheme pre-cools the circuit breaker by placing the semiconductor cooling chip tightly against the heat sink and using active cooling technology to reduce the equipment temperature and improve the breaking capacity. Simultaneously, by drilling holes in the connecting copper busbar, the cooling effect is concentrated, further improving heat dissipation efficiency. In this way, the operating temperature of the circuit breaker can be effectively reduced, thereby improving its breaking capacity and ensuring that the circuit breaker can still operate safely and stably in high-temperature environments.

[0069] If the breaking capacity index reaches the first index limit, it indicates that the circuit breaker's breaking capacity is within the normal range. At this point, it's necessary to further determine whether the insulation performance index reaches the second index limit. The second index limit is a threshold set based on the circuit breaker's insulation performance requirements, used to determine whether the circuit breaker needs insulation optimization. If the insulation performance index does not reach the second index limit, it indicates potential risks such as insulation aging, moisture absorption, or flashover. In this case, the system will retrieve the pole insulation scheme from the predetermined optimization strategy to perform pole insulation encapsulation on the circuit breaker. The pole insulation scheme refers to casting the circuit breaker's arc-extinguishing chamber, conductive rod, and integrated sensor into a single unit using epoxy resin. This encapsulation method effectively improves the circuit breaker's insulation performance, prevents short-circuit accidents caused by insulation aging or moisture absorption, and ensures the safe operation of the power system.

[0070] If the insulation performance index reaches the second index limit, it indicates that the circuit breaker's insulation performance is within the normal range. At this point, it is necessary to further determine whether the mechanical performance index reaches the third index limit. The third index limit is a threshold set based on the circuit breaker's mechanical performance requirements, used to determine whether the circuit breaker needs mechanical optimization. If the mechanical performance index does not reach the third index limit, it indicates a potential problem with the circuit breaker's mechanical operation, such as contact wear, loose mechanical parts, or rebound. In this case, the system will invoke the oil buffer scheme from the predetermined optimization strategy for vibration reduction control. This scheme controls mechanical vibration during the opening and closing process by replacing the traditional rubber pad with a hydraulic buffer, reducing operational impact and improving mechanical performance and service life.

[0071] If the mechanical performance index reaches the third index limit, it indicates that the circuit breaker's mechanical performance is in good condition. The final optimization step then proceeds to retrieve the dual-enhancement scheme from the predetermined optimization strategy to improve the circuit breaker's performance. The dual-enhancement scheme includes a first enhancement scheme and a second enhancement scheme, which optimize the equipment's electrical control and key components, respectively. The first enhancement scheme enhances the circuit breaker's breaking performance and response speed by increasing the control voltage, ensuring stable operation under various conditions. The second enhancement scheme replaces the press-fit IGBT chip with a welded IGBT chip. Welded chips offer stronger overload resistance and higher electrical efficiency, effectively improving the overall performance of the circuit breaker and enabling it to maintain efficient and stable operation even under complex conditions.

[0072] Through the above steps, the corresponding optimization strategies can be evaluated and retrieved item by item based on the dynamic performance index of the circuit breaker, ensuring that the circuit breaker can always maintain its optimal operating state under different operating conditions. This optimization control strategy based on dynamic performance index not only improves equipment safety but also extends its service life and reduces the risk of sudden failures.

[0073] In some possible embodiments, activating the integrated sensor to collect multi-sensor data (such as current, voltage, temperature, displacement, and insulation data) is a core step. However, in some embodiments, the synchronization problem of sensor data acquisition is not addressed. For example, the sampling frequencies and timestamps of the current sensor and displacement sensor may be inconsistent (the current sampling period may be 500ms, while the displacement sampling period may be 100ms), resulting in asynchronous sensing and monitoring information in the time dimension. This asynchrony causes phase shifts in the integration of operating status data, vacuum interrupter contact displacement data, and pole insulation performance data, thereby affecting the accuracy of the performance evaluation mechanism. Especially under high load conditions, data latency may be amplified, making it impossible for dynamic performance indices to truly reflect the instantaneous state of the equipment, reducing the real-time performance and reliability of optimized control. Essentially, this deficiency stems from the lack of a unified timing coordination mechanism in the data acquisition module, representing a deficiency at the method implementation level.

[0074] Therefore, as an implementation method, to address this deficiency, this embodiment embeds a distributed time synchronization coprocessor in the real-time sensing and monitoring module. This coprocessor, as a hardware submodule, is integrated within the integrated sensor and provides a unified timestamp reference for all sensors via GPS or a high-precision clock source. Specifically, the coprocessor first dynamically calibrates the sampling periods of each sensor (current, voltage, temperature, displacement, insulation detection). For example, it aligns the 100ms sampling period of the displacement sensor with the 500ms period of the current sensor to the same time grid using an interpolation algorithm. Secondly, the coprocessor employs a data buffer queue mechanism to temporarily store and sort asynchronously arriving data, ensuring that the operating status data, vacuum interrupter contact displacement data, and pole insulation performance data are time-synchronized before being combined to form the sensing and monitoring information. Finally, the coprocessor performs real-time data fusion through an edge computing unit to eliminate phase offset and output time-consistent sensing and monitoring information. This embodiment directly extends the functionality of the real-time sensing and monitoring module without changing the sensor deployment; it only requires adding a coprocessor chip at the hardware layer and updating the data acquisition logic at the software layer.

[0075] This embodiment significantly improves data synchronization. The technical effects are: the temporal consistency of sensing and monitoring information is improved by more than 90%, ensuring that the performance evaluation mechanism is based on accurate data sources; the dynamic performance index can better reflect the true state of the equipment, and the control response latency is optimized and reduced to the millisecond level; at the same time, through hardware-level time synchronization, the system's dependence on network conditions is reduced, and the robustness under complex working conditions is enhanced.

[0076] In summary, the embodiments of this application have at least the following technical effects:

[0077] This application integrates sensors to monitor the electrical, mechanical, and insulation status of circuit breakers in real time, enabling comprehensive and accurate acquisition of equipment operating data and improving the accuracy of equipment health status assessment. Based on real-time monitoring data and combined with a performance evaluation mechanism, it dynamically calculates and derives the dynamic performance index of the circuit breaker, achieving performance evaluation and prediction under different operating conditions. According to the dynamic performance index, it automatically retrieves predetermined optimization strategies to optimize the circuit breaker in terms of heat dissipation, insulation, mechanical control, and other aspects, ensuring that the equipment always maintains optimal operating conditions. Through intelligent optimization control and preventive adjustments, it reduces the occurrence of overload, overheating, and wear problems, extends the service life of the equipment, and reduces the failure rate. Through automated equipment monitoring and control, it reduces reliance on manual intervention, improves operation and maintenance efficiency, and lowers equipment management costs. By precisely controlling and optimizing circuit breaker performance, it enhances the stability and safety of the power distribution system, reduces outages or accidents caused by equipment failures, and ensures the reliable operation of the power system.

[0078] This technology achieves the goal of improving the performance stability and service life of circuit breakers under complex operating conditions through real-time multi-dimensional monitoring and dynamic performance evaluation, combined with intelligent optimization control strategies.
