Description

Technical Field

[0001] The present invention relates to the field of electric power engineering, and in particular to a handheld CT loop operation process review and safety assessment device and method. Background Art

[0002] With the continuous expansion of the scale and complexity of power systems, the importance of power grid safety has become increasingly prominent. In the power grid, the current transformer (CT) is a key component, and the correctness and reliability of its secondary circuit are crucial to the normal operation of the relay protection system. However, the existing CT circuit operation process review and safety assessment methods mainly rely on the subjective experience of operators, lack of objective supervision and intelligent real-time monitoring methods, which poses a great safety hazard in actual operation.

[0003] For example, patent CN112485751A describes a device for collecting information and providing comprehensive early warning for live work during power maintenance. The device monitors the safety status, health status, and working status of the operator through multiple monitoring units to provide early warning information. Although the device provides a certain degree of safety in monitoring and early warning, it does not directly solve the safety problem of the CT circuit terminal block during operation, especially in preventing accidental contact, accidental removal, and accidental wiring.

[0004] On the other hand, patent CN1 17613626A proposes a method for sealing and restoring the secondary current loop of a running CT, which uses physical insulation, closed isolation and short-circuiting technology to seal and restore the CT secondary loop to avoid the risk of an open circuit on the CT secondary side during equipment maintenance. However, this method requires tedious preparations before maintenance, and in actual operation, human factors may lead to incomplete isolation or short-circuiting errors, thus causing safety accidents.

[0005] In view of the deficiencies in the prior art, the present invention provides a handheld CT loop operation process review and safety assessment device and method. Summary of the invention

[0006] The purpose of the present invention is to provide a handheld CT circuit operation process audit and safety assessment device and method to solve the problems that the existing CT circuit operation relies on subjective experience, lacks objective supervision, and cannot monitor the live state in real time.

[0007] To achieve the above purpose, the following technical solution is adopted.

[0008] A handheld CT circuit operation process review and safety assessment device, comprising an intelligent safety measure baffle installed and locked on a CT circuit terminal block and a handheld device used by an operator;

[0009] The handheld device includes a first communication module for connecting and communicating with the intelligent safety measures baffle, an input module for inputting a CT circuit number and a work task, a handheld current monitoring module for real-time monitoring of the potential of the CT circuit terminal block, an identification module for identifying the identity of the operator, and a data processing module; the data processing module is used to process data from the first communication module, the input module, the handheld current monitoring module, the identification module, and the intelligent safety measures baffle, and after confirming that the CT circuit number is correct, the operator's identity authentication has passed, and the CT circuit terminal block is in a non-energized state, an unlocking command is sent to the intelligent safety measures baffle through the first communication module; the intelligent safety measures baffle is used to unlock the baffle of the CT circuit terminal block corresponding to the CT circuit number after receiving the unlocking command.

[0010] Optionally, the intelligent safety measure baffle includes a baffle, a real-time current detection module, a baffle opening module and a second communication module. There are multiple baffles, which correspond one-to-one to the CT circuit terminal blocks and block the corresponding CT circuit terminal blocks. The real-time current detection module is used to monitor the current of the CT circuit terminal block in real time. The baffle opening module is used to open the corresponding baffle after receiving the unlocking instruction. The communication module is electrically connected to the real-time current detection module and the baffle opening module, and is used to communicate with the first communication module.

[0011] Optionally, the recognition module includes but is not limited to a facial recognition module or a fingerprint recognition module.

[0012] Optionally, the handheld device further comprises a power module for providing power to the handheld device and the intelligent safety measure baffle.

[0013] Optionally, the handheld device further comprises a connecting wire, one end of which is connected to the first communication module and the power supply module, and a plug interface is provided on the intelligent safety measure baffle for connecting the second end of the connecting wire.

[0014] Optionally, the data processing module is provided with a database, in which the identity information of the operators, the work task information and the corresponding CT circuit number information are stored.

[0015] Optionally, the handheld device further comprises a display module for displaying operation information and safety status.

[0016] A handheld CT loop operation process review and safety assessment method, comprising the following steps:

[0017] Input the current work task and the CT circuit number to be operated through the input module of the handheld device;

[0018] The data processing module receives the input content of the input module, matches the input work task with the work task in the database, and determines whether the input CT circuit number is consistent with the CT circuit number corresponding to the work task in the database;

[0019] If the numbers are consistent, the staff member’s identity is identified through the identification module, and the identification result is sent to the data processing module. If the numbers are inconsistent, the review fails;

[0020] If the data processing module confirms that the identity of the operator is correct, the handheld current monitoring module and the current real-time monitoring module monitor the CT circuit terminal block potential of the CT circuit number to obtain the monitoring result. If the identity of the operator is incorrect, the audit fails;

[0021] If the data processing module confirms that the potential of the CT circuit terminal block is 0 in the monitoring results, the operation process is confirmed to be safe and an unlocking instruction is sent to the intelligent safety measure baffle. Otherwise, the review fails;

[0022] After receiving the unlocking command, the intelligent safety measure baffle unlocks the baffle of the CT circuit terminal block corresponding to the CT circuit number.

[0023] Optionally, when the audit fails, the reason for the failure is displayed through the display module.

[0024] Optionally, the following steps are also included:

[0025] While the operator is performing CT circuit operation, the handheld current monitoring module or the current real-time monitoring module continuously monitors the potential of the CT circuit terminal block;

[0026] If an abnormal potential is detected, a warning will be immediately issued through the display module, and the data processing module will automatically record the abnormal situation;

[0027] After the operator completes the CT circuit operation, the data processing module again checks the potential of the CT circuit terminal block through the current real-time monitoring module;

[0028] Confirm that the potential of the CT circuit terminal block is 0, and send a locking command to relock the intelligent safety measure baffle;

[0029] The operation completion information is fed back through the input module of the handheld device; the data processing module receives the feedback of the operation completion and updates the work task status in the database.

[0030] Compared with the prior art, the present invention has the following beneficial effects:

[0031] The present invention uses an input module of a handheld device so that operators can accurately input CT circuit numbers and work tasks. The data processing module ensures the correctness of the operated CT circuit number by comparing it with the information in the database, thereby reducing erroneous operations caused by human errors.

[0032] The present invention utilizes an identification module, such as facial recognition or fingerprint recognition, and provides an objective identity verification method to ensure that only authorized operators can operate the CT circuit, thereby effectively preventing unauthorized misoperation.

[0033] The combined use of the handheld current monitoring module and the current real-time monitoring module of the present invention enables the present invention to monitor the potential of the CT circuit terminal block in real time. Once an abnormal potential is found, a warning is immediately issued through the display module, effectively preventing safety accidents caused by mistaken disassembly or accidental contact with live circuits.

[0034] The processing logic and decision-making mechanism of the data processing module of the present invention make the operation process review and safety assessment more intelligent, reduce the dependence on the subjective experience of operators, and improve the safety of power grid operation.

[0035] The present invention stores the operator's identity information, work task information and corresponding CT circuit number information in a database, and the present invention ensures that each operation has a detailed record, which is convenient for subsequent review and evaluation.

[0036] The design of the first communication module and the second communication module of the present invention ensures that the communication connection between the handheld device and the intelligent safety measure baffle is stable and reliable, providing a guarantee for the smooth progress of the operation process.

[0042] The present invention will be described in detail below with reference to the accompanying drawings and in combination with embodiments. It should be noted that the embodiments and features in the embodiments of the present application can be combined with each other without conflict.

[0043] The following detailed description is an exemplary description, which is intended to provide further detailed description of the present invention. Unless otherwise specified, all technical terms used in the present invention have the same meaning as those generally understood by those skilled in the art to which the present application belongs. The terms used in the present invention are only for describing specific embodiments, and are not intended to limit exemplary embodiments according to the present invention.

[0044] Example 1

[0045] like Figure 1 and Figure 2 As shown, the handheld CT circuit operation process audit and safety assessment device of the present invention mainly includes an intelligent safety measure baffle 1 installed on the CT circuit terminal block and a handheld device 2 used by the operator.

[0046] Intelligent safety measure baffle 1: designed to cover the CT circuit terminal block to prevent direct contact. A locking mechanism is installed on the baffle 11 to ensure that the baffle 11 remains locked before receiving an unlocking command. The baffle 11 communicates with the handheld device 2 through the second communication module to receive the unlocking command.

[0047] Handheld device 2: includes the following key components:

[0048] The first communication module is used to realize wireless or wired communication with the intelligent safety measure baffle 1 and send an unlocking instruction.

[0049] Input module 21: allows operators to input CT circuit numbers and work tasks. Input module 21 can be a touch screen, a physical keyboard or a voice recognition system to adapt to different operating environments and user preferences.

[0050] Handheld current monitoring module 23: integrated in the handheld device 2, used to monitor the potential of the CT loop terminal block in real time. The module can be a current transformer or other suitable potential detection equipment.

[0051] Identification module: used to verify the identity of the operator. In this embodiment, the identification module is a facial recognition system that captures the operator's facial features through a camera and compares them with pre-stored data to confirm the identity.

[0052] The data processing module, as the core processing unit, receives and processes data from the input module 21, the handheld current monitoring module 23 and the identification module. The data processing module performs logical judgment, and after ensuring that all conditions are met, sends an unlocking instruction to the intelligent safety measure baffle 1 through the first communication module.

[0053] Operation process:

[0054] The operator inputs the CT circuit number and work task through the input module 21 .

[0055] The handheld current monitoring module 23 monitors the potential of the CT loop terminal block and sends the data to the data processing module.

[0056] The recognition module performs facial recognition on the operator and sends the verification result to the data processing module.

[0057] The data processing module integrates the CT loop number, the operator's identity authentication result and the potential monitoring data, and after confirming that all conditions are met, sends an unlocking command to the intelligent safety measure baffle 1.

[0058] After receiving the unlocking instruction, the intelligent safety measure baffle 1 unlocks the baffle 11 of the CT circuit terminal block corresponding to the CT circuit number, allowing the operator to operate.

[0059] Through this implementation, the present invention provides an efficient and reliable CT loop operation process review and safety assessment method, which effectively reduces the risk of misoperation and improves the safety of power grid operation.

[0060] As a specific example, the intelligent safety measure baffle 1 includes:

[0061] Baffle 11: It is a physical barrier designed to cover and protect the CT circuit terminal block to prevent unauthorized or misoperation. Each baffle 11 corresponds to a CT circuit terminal block to ensure specific protection.

[0062] Current real-time detection module 12: integrated in each baffle 11, used to continuously monitor the current state of the corresponding CT loop terminal block. This module can be a current transformer or other types of current sensors, which can detect and feedback current information in real time.

[0063] The baffle opening module 13 includes a mechanical or electronic lock mechanism, which is used to unlock and open the baffle 11 after receiving an unlocking command. The module can be a locking system driven by an electric motor to ensure that the opening and closing operations of the baffle 11 are safe and reliable.

[0064] The second communication module is responsible for communicating with the first communication module of the handheld device 2. This module can be a wireless communication module, such as Wi-Fi, Bluetooth or Zigbee, or a wired connection, such as RS-485 or Ethernet, for transmitting unlocking instructions and current monitoring data.

[0065] The current real-time detection module 12, the baffle opening module 13 and the second communication module are connected via circuits to ensure accurate transmission of data and instructions. This electrical connection can be a direct cable connection or a conductive path on a circuit board.

[0066] The operator inputs the CT circuit number and work task through the handheld device 2.

[0067] The data processing module of the handheld device 2 verifies the input information, and communicates with the second communication module of the intelligent safety measure baffle 1 to send an unlocking instruction.

[0068] The second communication module of the intelligent safety measure baffle 1 receives the unlocking instruction and transmits it to the baffle opening module 13 through the circuit, triggering the baffle 11 to unlock.

[0069] At the same time, the current real-time detection module 12 monitors the current state of the CT circuit terminal block to ensure that the circuit is in a safe state, such as no current, before unlocking.

[0070] The design of the intelligent safety measure barrier 1 ensures that only verified operators can operate the specific CT circuit terminal block under any circumstances.

[0071] The real-time monitoring function of the current real-time detection module 12 provides an additional layer of safety to prevent the baffle 11 from being unlocked in a live state.

[0072] The intelligent safety measure baffle 1 of the present invention not only provides physical protection, but also enhances the safety and accuracy of CT loop operation through real-time monitoring and communication mechanisms, effectively preventing misoperation and safety accidents.

[0073] As a specific example, the recognition module can be a facial recognition module or a fingerprint recognition module. The facial recognition module includes a high-resolution camera to capture the facial features of the operator. Through advanced image processing algorithms, the system is able to extract key facial feature points, such as the position and shape of the eyes, nose, mouth, and facial contours. These feature points are then compared with the facial features of authorized operators stored in the database to verify the identity of the operator. The facial recognition process is fast and accurate, and can be automatically triggered when the operator approaches the equipment without additional operation.

[0074] Fingerprint Recognition Module: As another form of identity verification, the fingerprint recognition module includes a fingerprint recognition sensor that scans the operator's fingerprint. The sensor captures the ridge and valley patterns of the fingerprint, which are unique to each individual. The collected fingerprint data will be matched with the records in the database to confirm the identity of the operator. The fingerprint recognition module has a high recognition rate and can adapt to different finger conditions, such as dry, wet or slightly damaged fingers.

[0075] The design of the recognition module allows the most appropriate recognition technology to be selected according to the actual application scenario and security requirements. The facial recognition module and the fingerprint recognition module can be used separately or integrated into the handheld device 2 at the same time to provide a dual verification mechanism to enhance security.

[0076] Data processing and feedback: Whether it is facial recognition or fingerprint recognition, the recognition module sends the collected data to the data processing module. The data processing module is responsible for executing the identity authentication algorithm and comparing it with the information in the database. The verification result will be fed back to the operator and sent to the intelligent safety measure baffle 1 through the first communication module to decide whether to unlock the baffle 11 of the CT circuit terminal block.

[0077] The identification module of the present invention not only provides a reliable identity authentication method, but also meets the needs of different application scenarios through flexible module selection and integration, while ensuring data security and privacy protection.

[0078] As a preferred example, the data processing module has one or more built-in databases for storing various types of information related to the CT circuit operation. These databases can be based on a relational database management system RDBMS, such as MySQL, Oracle or SQLite, or an object-oriented database system to adapt to different data structures and query requirements.

[0079] The database stores detailed information about operators, including but not limited to name, employee number, position, operation permission level, and biometric feature data such as facial recognition feature vectors or fingerprint templates. This information is used to verify the identity of operators during operations.

[0080] The database also stores relevant information about the work tasks, including task number, task description, expected completion time, CT circuit number of the required operation, and safety requirements and operating guidelines related to the task.

[0081] The number information of each CT circuit terminal block is also recorded in the database, and these numbers are associated with the work task information to ensure that the operator operates the correct CT circuit.

[0082] In the operation process, the data processing module receives the CT loop number and work task information input by the operator through the input module 21, and then matches it with the information stored in the database to verify the legitimacy of the task and the correctness of the CT loop.

[0083] The database is designed to be updated in real time to reflect the latest work assignment and operator changes. In addition, the database can also be synchronized with a remote server to share information between multiple handheld devices 2.

[0084] The database uses encryption measures to protect stored information and prevent unauthorized access. At the same time, for sensitive information such as biometric data, additional security measures are implemented, such as using hash functions to store biometric templates to ensure that personal privacy is not leaked.

[0085] The database design takes into account future scalability, allowing new data fields or tables to be added to adapt to changing business needs and technological developments.

[0086] The data processing module and its database of the present invention not only provide a reliable information management and verification platform for CT loop operation, but also meet the strict requirements of the power engineering field by ensuring the security and privacy protection of data. In addition, the scalability of the database facilitates future technology upgrades and functional expansions.

[0087] As a preferred example, the handheld device 2 includes a display module 22, which may be a liquid crystal display LCD, an organic light emitting diode display OLED or other types of flat panel displays. The size and resolution of the display module 22 are designed to be large and clear enough to provide good visibility under various light conditions, including strong outdoor light.

[0088] The display module 22 is used to display all key information required by the operator during the operation, including but not limited to the CT circuit number, work task description, operation steps, current operation status and any necessary safety warnings or prompts.

[0089] The display module 22 updates and displays the safety status of the CT circuit terminal block in real time, including the current monitoring result, the operator identity authentication status, and the locking or unlocking status of the intelligent safety measure baffle 1.

[0090] The display module 22 runs a user interaction interface that is designed to be intuitive and easy to use, allowing operators to input or confirm information through a touch screen, or navigate and select through physical buttons.

[0091] In order to accommodate operators from different regions and language backgrounds, the display module 22 supports multi-language display, and operators can select different language interfaces as needed.

[0092] Dustproof and waterproof design: Considering the harsh conditions that may exist at the power engineering site, the display module 22 adopts a dustproof and waterproof design to ensure stable operation in various environments.

[0093] Fault prompts and diagnostic information: When the system fails or requires maintenance, the display module 22 can display the corresponding error code or diagnostic information to help operators or maintenance personnel quickly identify and solve the problem.

[0094] Example 2

[0095] The handheld device 2 also includes a power module, which is the core component of the handheld device 2 and is responsible for providing a stable power supply to all electronic components of the device. The module can be a built-in rechargeable lithium-ion battery or a replaceable battery pack to ensure power requirements during long-term operation.

[0096] The power module is designed to be able to provide power to both the handheld device 2 and the smart safety measure shield 1. This is achieved through a central power management system that can intelligently distribute power to ensure power stability for both devices during operation.

[0097] The power module includes a power management unit that monitors the battery status, including power level, charging status and battery health. The unit is also responsible for issuing warnings when the battery is low, prompting operators to charge or replace the battery in time.

[0098] The handheld device 2 is equipped with a standard USB-C or similar interface, allowing charging using a standard charger or power adapter. In addition, the power module also supports fast charging technology to shorten charging time and improve work efficiency.

[0099] To extend battery life and reduce energy consumption, the power module integrates a variety of energy-saving features, such as automatically entering low-power mode when not in use, and automatically shutting down after a long period of inactivity. The power module is designed with the harsh conditions of outdoor and industrial environments in mind, including dustproof, waterproof and impact-resistant features to ensure reliable operation in a variety of environments. The power module also includes overcharge, over-discharge, short-circuit and overheating protection to prevent battery damage and potential safety risks.

[0100] The power module of the present invention not only ensures the continuous operation of the handheld CT loop operation process audit and safety assessment device, but also improves the efficiency and reliability of the device through intelligent power management and energy-saving characteristics. At the same time, the consideration of environmental adaptability and safety characteristics enables the device to operate stably in various complex environments in the field of power engineering.

[0101] As a preferred example of the above example, a connecting line 24 is also provided. The connecting line 24 is a durable cable suitable for industrial environments, and connectors matching the handheld device 2 and the intelligent safety measure baffle 1 are respectively designed at both ends. The design of the connecting line 24 takes anti-interference and electromagnetic compatibility into consideration to ensure stable communication in high voltage and strong electromagnetic field environments.

[0102] One end of the connection line 24 is connected to the first communication module in the handheld device 2, which is responsible for wireless or wired data transmission with the intelligent safety measure baffle 1. The first communication module may include one or more interfaces, such as USB, RS-232 or RS-485, to adapt to different types of connection lines 24 and communication protocols.

[0103] The same end of the connection line 24 is also connected to the power module of the handheld device 2 to ensure that the power module can provide stable power to the communication module. The power module is designed to adapt to the power transmission requirements of the connection line 24, including voltage and current matching.

[0104] The intelligent safety measure baffle 1 is provided with a plug interface that matches the second end of the connection line 24. The plug interface is designed to withstand frequent plugging and unplugging operations while ensuring the reliability and durability of the connection.

[0105] The connection line 24 is not only used for power transmission, but also may be used for transmitting data signals to achieve two-way communication between the handheld device 2 and the intelligent safety measure baffle 1. This design allows real-time monitoring of data transmission and the sending of unlocking instructions.

[0106] Considering the safety requirements in the field of power engineering, the connecting wire 24 is wrapped with insulating material to prevent leakage and short circuit. In addition, the connecting wire 24 may also be equipped with a safety lock to prevent accidental disconnection.

[0107] The connection line 24 ensures the reliability and safety of the handheld CT loop operation process audit and safety assessment device, while providing a simple and effective physical connection method to achieve communication and power supply between devices.

[0108] Example 3

[0109] like Figure 3 As shown, a handheld CT loop operation process review and safety assessment method includes the following steps:

[0110] The operator uses the input module 21 of the handheld device 2 to input the details of the upcoming work task and the corresponding CT circuit number. The input module 21 can be a touch screen, a physical keyboard or a voice recognition system to adapt to different operating habits and environments.

[0111] After receiving the input information, the data processing module compares it with the work task information in the built-in database to verify whether the input CT circuit number matches the CT circuit number corresponding to the work task recorded in the database.

[0112] If the CT loop number is verified, the data processing module activates the identification module to authenticate the operator. The identification module can be a facial recognition system or a fingerprint recognition system, which compares the collected biometric data with the information in the database.

[0113] After the identity verification is correct, the data processing module instructs the handheld current monitoring module 23 and the current real-time monitoring module to monitor the potential of the specified CT circuit terminal block. The two modules send the real-time monitoring data to the data processing module to determine whether the CT circuit terminal block is in a non-energized state.

[0114] If all monitoring results indicate that the potential of the CT circuit terminal block is 0, that is, it is confirmed to be in a safe state, the data processing module will send an unlocking command to the intelligent safety measure baffle 1 to allow the operator to operate.

[0115] After the intelligent safety measure baffle 1 receives the unlocking instruction, its baffle opening module 13 will perform the unlocking operation, releasing the baffle 11 of the CT circuit terminal block corresponding to the CT circuit number, so that the operator can safely perform subsequent operations.

[0116] At each key step of the operation process, the display module 22 of the handheld device 2 will display relevant information and safety status, including but not limited to CT circuit number, work task, operator identity authentication result, potential monitoring result and the locked or unlocked status of the baffle 11.

[0117] If an abnormality is found in any step, such as inconsistent CT circuit numbers, operator identity verification failure, or CT circuit terminal block being energized, the handheld device 2 will immediately notify the operator through the display module 22 and record the relevant abnormal information for subsequent analysis.

[0118] Key information in the entire operation process, including operation time, operator, operation results, etc., will be recorded in the database of the handheld device 2 for future audit and tracking.

[0119] The method of the present invention ensures the safety and accuracy of CT loop operation, significantly reduces the risk of misoperation through multi-level verification and real-time monitoring, and improves the safety of power grid operation.

[0120] As a specific example, in the case where the audit fails, the specific reason for the audit failure is clearly displayed to the user through the display module 22:

[0121] When the operator inputs the CT circuit number and the work task information through the input module 21 of the handheld device 2, the data processing module compares the information with the records in the database. If the input CT circuit number is inconsistent with the CT circuit number corresponding to the work task recorded in the database, the display module 22 will display an error message "The input CT circuit number does not match the database record".

[0122] After the CT loop number verification is passed, if the identification module finds that the identity information does not match the information stored in the database when performing the operator identity verification, the display module 22 will display a prompt of "operator identity verification failed".

[0123] If the identity verification is correct, if the handheld current monitoring module 23 and the current real-time monitoring module detect that the potential of the CT loop terminal block is not 0, the display module 22 will display a warning message "The potential of the CT loop terminal block is abnormal and there is a risk of being electrified".

[0124] If the data processing module attempts to send an unlock command to the intelligent safety measure baffle 1 after confirming that all conditions are met, but fails to send it successfully due to communication failure or other reasons, the display module 22 will prompt "Unlock command failed to send, please check the communication connection".

[0125] When the intelligent safety measure baffle 1 fails to successfully receive the unlocking instruction or the baffle opening module 13 fails to perform the unlocking operation, the display module 22 will display the message "Baffle unlocking failed, please try again or contact technical support".

[0126] In the case of each audit failure, the data processing module will record the failure reason, time and related operation information in the operation log, and provide it to the operator through the display module 22 for viewing, so as to diagnose the problem and make subsequent improvements.

[0127] As a preferred example, the method further includes the following steps:

[0128] During the operation of the CT circuit by the operator, the handheld current monitoring module 23 or the current real-time monitoring module is activated to continuously monitor the potential of the CT circuit terminal block. These modules are designed to provide real-time potential data during the operation to ensure the safety of the operation.

[0129] If the potential of the CT circuit terminal block is detected to be abnormal, that is, inconsistent with the expected non-energized state, the display module 22 will immediately display a warning message, such as "Abnormal potential detected, please stop operation immediately". At the same time, the data processing module will automatically record the abnormal situation, including timestamp, potential value and possible error code, for subsequent analysis and audit.

[0130] After the operator completes the CT circuit operation, the data processing module will again instruct the current real-time monitoring module to check the potential of the CT circuit terminal block. If the potential is confirmed to be 0, that is, the CT circuit terminal block is in a safe state, the data processing module will send a locking command to the intelligent safety measure baffle 1.

[0131] After the intelligent safety measure shutter 1 receives the locking instruction, its shutter opening module 13 will perform a locking operation to ensure the safety of the CT circuit terminal block during non-operation.

[0132] The operator inputs the information of operation completion through the input module 21 of the handheld device 2 to confirm that all steps have been correctly executed and the CT circuit terminal block has been restored to a safe state.

[0133] After receiving feedback that the operation is completed, the data processing module will update the work task status in the database, mark the task as completed, and record the time and related information of the operation completion.

[0134] After the operation is completed, the system will continue to monitor the status of the CT circuit terminal block to ensure that the CT circuit terminal block is still in a safe state after the operator leaves the site. In addition, all recorded data will be used for regular maintenance and system performance evaluation.

[0135] The method of the present invention not only provides continuous safety monitoring during operation, but also ensures the long-term safety of the CT circuit and the traceability of the system by re-locking the intelligent safety measure baffle 1 and updating the database after the operation is completed. This series of steps enhances the safety of CT circuit operation, reduces the risk of misoperation, and improves the stability of power grid operation.
