[0108] S22 deploys a DTU data transmission unit and integrates a 4G / 5G dual-mode communication module to support edge computing functions, perform local preprocessing on the data collected by the sensor, and filter abnormal data (data with a deviation exceeding ±5% is marked as abnormal).

[0109] S23. A multi-source data fusion algorithm is embedded in the DTU data transmission unit to fuse real-time sensor data with external environmental data (such as outdoor wind speed, salt spray concentration, and atmospheric pressure, obtained through linkage with regional meteorological stations), establish a correlation model between equipment status and environmental impact, eliminate false monitoring caused by environmental interference, and improve data reliability by ≥98%.

[0110] S24. The sensor is calibrated using a standard signal source. The current sensor is input with a standard current generator at 10%, 50%, and 100% of the rated current, and the voltage sensor is input with 80%, 100%, and 120% of the rated voltage to ensure that the measurement error complies with GB / T3906-2020 standard. Communication tests are performed on the DTU data transmission unit to ensure that the data transmission delay is ≤50ms and the packet loss rate is ≤0.1%.

[0111] S3, Dynamic Operation Status Intelligent Control Step: Based on the sensor deployment scheme, configuration parameters, equipment status data and calibration parameters output by the intelligent monitoring system deployment and calibration steps, a closed-loop control is formed through real-time acquisition, status evaluation and command execution, so as to be able to adopt differentiated control strategies for different operating states, and combine machine learning to dynamically optimize control parameters, outputting equipment operating status evaluation results, command execution feedback information, load transfer execution results and optimized control parameters;

[0112] The specific steps of S3 are as follows:

[0113] S31, through deployed sensors and DTU data transmission unit, collects operating parameters such as insulation medium humidity, air chamber temperature, main circuit current and voltage, and partial discharge in real time, with a collection frequency of 1 time / second;

[0114] S32, based on preset thresholds (such as partial discharge ≤10pC, gas chamber temperature ≤65℃, main circuit current ≤630A), evaluates the collected data through edge computing of the DTU data transmission unit to determine whether the equipment is in normal operation, warning or fault state;

[0115] S33 executes corresponding instructions for normal operation, early warning, or fault status;

[0116] Normal state: Maintain the current operating mode, keep the three-position disconnect switch closed, and operate the vacuum circuit breaker according to the preset parameters;

[0117] Warning status (e.g., partial discharge 8~10pC, temperature 60~65℃): Start the air chamber cooling fan, adjust the dry air circulation rate, and send the warning information to the operation and maintenance platform at the same time.

[0118] Fault conditions (e.g., partial discharge > 10pC, short circuit current > 20kA): The DTU data transmission unit immediately sends a trip command to the vacuum circuit breaker to disconnect the main circuit, and at the same time controls the three-position disconnecting switch to the ground position to ensure the equipment is safe from power failure.

[0119] S34, when this ring main unit is in an early warning state, it will link with 2-3 adjacent ring main units through the distribution network communication network to obtain their load rate and operating status; if the load rate of the adjacent equipment is ≤70%, a load transfer command will be sent to distribute 10%-20% of the load of this equipment to the adjacent equipment by adjusting the tie switch, so as to avoid a single equipment being in an early warning state for a long time and extend its service life.

[0120] S35 adjusts the warning threshold and control response time based on historical operating data (last 30 days) using machine learning algorithms. For example, during the high-temperature period in summer, the temperature warning threshold is lowered by 5°C to improve control sensitivity.

[0121] S4, Full life cycle protection and maintenance steps: Based on the equipment operation status evaluation results, instruction execution feedback information, load transfer execution results and optimized control parameters output by the dynamic operation status intelligent control steps, remote review and on-site inspection are carried out to realize intelligent replenishment and update of insulation medium, and rapid source tracing and repair based on fault data, while targeted compensation is carried out for component performance degradation data.

[0122] The specific steps of S4 are as follows:

[0123] S41, conduct a comprehensive data review every 3 months through the remote monitoring system, and also conduct on-site inspections every 6 months, focusing on checking the integrity of the sealing structure, the working status of the sensors, and the aging of environmentally friendly material components;

[0124] S42 uses air chamber pressure monitoring data to automatically activate the dry air replenishment device when the pressure is below 0.1MPa, until the pressure is replenished to the rated pressure of 0.15~0.2MPa; and regularly (every 5 years) the insulating medium is completely replaced to ensure insulation performance;

[0125] S43, when a fault occurs, based on the collected fault data (such as short-circuit current peak, fault occurrence time, and abnormal sensor nodes), locates the faulty component (such as the vacuum circuit breaker arc-extinguishing chamber and sealing ring), and generates a repair plan to guide maintenance personnel to replace it quickly.

[0126] S44 addresses the performance degradation of BMC / DMC material components by monitoring changes in the operating torque of the mechanism. When the torque increases by more than 15%, a lubrication maintenance procedure is initiated to replenish environmentally friendly lubricant, ensuring the operational flexibility of the components.

[0127] Although the present invention has been described above with reference to embodiments, various modifications can be made and components can be replaced with equivalents without departing from the scope of the invention. In particular, as long as there is no structural conflict, the features in the disclosed embodiments can be combined with each other in any manner. The lack of an exhaustive description of these combinations in this specification is merely for the sake of brevity and resource conservation. Therefore, the present invention is not limited to the specific embodiments disclosed herein, but includes all technical solutions falling within the scope of the claims.
