[0057] S1. The multi-physics field coupling detection unit 6 is started, the optical fiber current sensor 9 collects the main circuit current value in real time, the millimeter wave radar temperature measurement module 10 synchronously monitors the temperature distribution and arc characteristic parameters of the fuse module 3 and the contact area, forming multi-dimensional operation data, and the Hall sensor 52 in the fuse status indication unit 50 continuously monitors the magnetic field changes around the fuse, providing auxiliary basis for judging the fuse status;

[0058] S2, the deep learning trigger judgment unit 7 receives sensor data, dynamically analyzes the current waveform, temperature trend and arc energy through the CNN-LSTM hybrid network, and optimizes the protection threshold in real time. When a current overload, temperature anomaly or arc energy exceeding the standard is detected, the protection instruction is immediately triggered. The edge computing unit 19 of the intelligent control module 4 synchronously performs time-frequency domain analysis of the local fault waveform and uploads key parameters to the cloud platform through the 5G network, supporting the multi-device collaborative early warning unit 20 to perform regional power grid status assessment;

[0059] S3. After receiving the protection command, the electromagnetic drive emergency processing mechanism 8 instantly generates a strong magnetic field with the strong magnetic field electromagnet, driving the ferromagnetic drive component rigidly connected to the titanium alloy connecting rod 16, thereby driving the titanium alloy connecting rod 16 and the movable contact 13 to separate from the first static contact 14 and the second static contact 15, thereby cutting off the fault circuit. If the overload persists, the secondary melt of the low-melting-point tin-bismuth alloy in the fuse module 3 will fuse first, and the primary melt of the nanocrystalline copper alloy will serve as backup protection, forming a double insurance mechanism. After the fuse blows, the electrical connection between the conductive block 17 and the fuse holder 18 is interrupted, completely isolating the fault point.

[0060] S4. After the Hall sensor 52 of the fuse status indication unit 50 detects a sudden change in the magnetic field, it triggers the dual-color LED light 51 to change from green to red, visually indicating the fuse status. The fuse signal is synchronously transmitted to the intelligent control module 4 through the electrical connection, triggering an alarm and recording the fault event to provide data support for subsequent maintenance;

[0061] The bionic honeycomb structure aluminum alloy of S5 and base 5 works synergistically with the micro heat pipe array 21. The nanofluid conducts heat efficiently in the heat pipe, and the graphene heat dissipation coating 22 enhances surface heat radiation, forming a three-dimensional thermal management network to prevent secondary failures caused by local overheating.

[0062] S6. After the fault is eliminated, the electromagnetically driven emergency processing mechanism 8 is controlled manually or remotely to drive the moving contact 13 to reclose with the first static contact 14 and the second static contact 15, thereby restoring the circuit connectivity. After the fuse module 3 is replaced, the system is reset, and the multi-physics field coupling detection unit 6 is restarted to enter a new round of monitoring cycle.

[0063] S7. The isolating switch unit 11 adopts a modular box structure, which is convenient for independent maintenance or replacement. It can be quickly unlocked through the limit groove 53 and the lock block 55 of the protective cover 25, and cooperated with the pressure spring 57 to achieve convenient disassembly and assembly.

[0064] Working principle: The three-level cascade architecture is conducive to significantly improving the efficiency and reliability of circuit protection. The multi-physical field coupling detection unit 6 integrates the optical fiber current sensor 9 and the millimeter wave radar temperature measurement module 10 to achieve accurate real-time monitoring of current, temperature and arc characteristics, and enhance the sensitivity and accuracy of fault detection. The deep learning trigger judgment unit 7 adopts the CNN-LSTM hybrid network to dynamically optimize the protection threshold, making the protection strategy adaptive and intelligent, and effectively responding to complex and changeable circuit environments. The electromagnetic drive emergency processing mechanism 8 uses strong magnetic field electromagnet drive technology to ensure rapid response and efficient execution, further shortening the fault processing time, improving system stability and safety, and thus helping to reduce the risks caused by circuit failures. Risk, play the role of emergency protection circuit, the fuse module 3 adopts a dual-fuse parallel structure design, which significantly improves the overload protection performance and reliability of the equipment, the main fuse is made of nanocrystalline copper alloy, with its high melting point and excellent conductivity, it ensures the stable transmission of current under normal working conditions, the auxiliary fuse is made of low melting point tin-bismuth alloy, which can quickly melt when the current is overloaded, effectively cut off the fault current, and form a dual protection mechanism. This design not only ensures the efficient operation of the equipment under rated load, but also can respond quickly in extreme cases to prevent circuit damage, and cooperates with the optimized layout of the conductive block 17 and the fuse holder 18 to further improve the installation convenience and contact stability of the equipment. By integrating the edge computing unit 19 and the multi-device collaborative early warning unit 20, it is realized Efficient and collaborative intelligent protection, the built-in fault waveform analysis algorithm of the edge computing unit 19 can quickly complete the time-frequency domain analysis of the local fault waveform, and combined with the 5G network to transmit key characteristic parameters to the cloud platform in real time, it not only ensures the immediacy of the analysis, but also reduces the data transmission delay, significantly improving the fault response speed. At the same time, the multi-device collaborative early warning unit 20 can automatically trigger the preventive protection strategy of the regional power grid when the same fault characteristics are detected in adjacent nodes, effectively expanding the fault monitoring range, enhancing the linkage protection capability of the power grid, forming a regional protection network, and significantly improving the stability and reliability of the overall power system. By using a composite design of bionic honeycomb structure aluminum alloy, micro heat pipe array 21 and graphene heat dissipation coating 22 on the base 5, the structure An efficient three-dimensional thermal management network has been built. The lightweight and high-strength characteristics of the bionic honeycomb structure, combined with the excellent thermal conductivity of aluminum alloy, effectively disperse the heat generated during equipment operation. The nanofluid filled in the micro heat pipe array 21 significantly improves the thermal conduction efficiency and accelerates the uniform diffusion of heat. The graphene heat dissipation coating 22 covered on the surface, with its excellent thermal conductivity, further enhances the heat dissipation effect. The three work together to form a full-scale, multi-level thermal management solution to ensure that the equipment maintains a stable temperature environment during high-load and long-cycle operation, significantly improving the stability and life of the equipment. By adopting a modular box structure and combining it with the integrated layout of the intelligent control console 12, the functionality and reliability of the equipment are significantly improved. The intelligent control console 12 is set in the center.It is convenient for centralized control and reduces electromagnetic interference. The electromagnetic shielding cavity 60 on the top effectively protects the sensitive deep learning trigger judgment unit 7 and the intelligent control module 4 inside. The drive room 28 adopts the design of the slide 29 and the fixed frame 30, which is not only convenient for the installation and maintenance of the electromagnetic drive emergency processing mechanism 8, but also realizes the flexible adjustment of the drive mechanism through the mobile room 59. The moving contact 13 connected with the titanium alloy connecting rod 16 ensures the precise and stable movement of the moving contact 13. In addition, the setting of the protective cover 25 further enhances the protection capability of the equipment. The overall structure is compact and efficient, which significantly improves the operating reliability, operation convenience and environmental adaptability of the equipment. Through the mechanical structure and electric control in the drive room 28 The setting of the components realizes efficient and stable transmission control and automatic operation. The slide 35, slider 36 and moving rod 32 and other components arranged in the transmission chamber 33 constitute an ingenious linkage mechanism, which cooperates with the composite movement of the passive rod 39, the moving sleeve 40 and the active rod 41 to ensure the precise control and flexible adjustment of the contact action. The electric control component adopts a servo motor 47 to drive the first gear 48 to transmit, which not only realizes the automatic rotation control of the rotating rod 42, but also ensures the stability and reliability of the transmission through the meshing design of the first gear 48 and the second gear 49. In addition, the design of the rotating rod 42 and the rotating handle 43 and the limiting block 44 on the top of the protective cover 25 supports both manual operation and automatic operation. The control function significantly improves the operational convenience and safety of the equipment. The overall structural layout is compact and the transmission efficiency is high, which effectively enhances the operational stability and intelligence level of the equipment. Through the coordinated work of the Hall sensor 52 and the two-color LED light 51, the intelligence and visualization level of the equipment status monitoring are significantly improved. The Hall sensor 52 senses the magnetic field changes when the fuse module 3 is blown in real time, accurately triggers the color switching of the two-color LED light 51, and provides intuitive status prompts for the operator. At the same time, the fuse signal is immediately transmitted to the intelligent control module 4 to realize remote monitoring and early warning, making equipment maintenance more proactive and efficient, thereby not only enhancing the accuracy of status recognition, but also through the optical signal and The dual feedback of electrical signals significantly improves the convenience of equipment management and the timeliness of system response. The limit slot 53 and limit block 54 at the bottom of the protective cover 25, combined with the setting of the lock block 55, lock slot 56 and pressure spring 57, significantly improve the safety protection performance and operational convenience of the equipment. The sliding connection between the limit slot 53 and the limit block 54, combined with the stable engagement of the lock block 55 and the lock slot 56, ensures the tight fixation between the protective cover 25 and the installation box 23, effectively preventing accidental loosening or falling off.
