Description

Technical Field

[0001] This invention relates to the field of smart circuit breaker technology, and more particularly to a smart circuit breaker with short-circuit alarm function. Background Technology

[0002] In modern society, electricity has become the core energy source supporting residential life, commercial operations, and industrial production. The safe and stable operation of the power system is directly related to the orderly development of the social economy. Circuit breakers, as indispensable control and protection core equipment in the power system, have the core responsibility of quickly disconnecting circuits and isolating faulty areas to prevent the spread of accidents when faults such as short circuits and overloads occur. With the rapid development of smart power systems, the traditional pure hardware protection mode of circuit breakers can no longer meet the needs of refined and intelligent management and control. Smart circuit breakers that integrate hardware execution and software intelligent analysis have become the core direction for technological upgrading in the industry.

[0003] Existing circuit breakers still have key technical pain points in practical applications: First, after a short-circuit fault occurs, the main power supply is quickly cut off. However, the alarm module of traditional circuit breakers relies on the main power supply, causing the alarm function to stop when the main power supply is interrupted, making it impossible to provide continuous warnings after a fault. Second, the transmission of fault information lacks accuracy. Existing equipment can only achieve basic trip protection, making it difficult to quickly locate the fault type, location, and severity. It also cannot push core fault information to user terminals or monitoring platforms, resulting in maintenance personnel being unable to respond and handle the situation in a timely manner, increasing the risk of the fault escalating. Summary of the Invention

[0004] The purpose of this invention is to address the shortcomings of existing technologies by proposing a smart circuit breaker with short-circuit alarm function.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: a smart circuit breaker with short-circuit alarm function, comprising a main circuit breaker module, a small motor installed inside the main circuit breaker module, a circuit adapter module and a network module installed on both sides of the main circuit breaker module, characterized in that: it further comprises a smart control system that establishes a bidirectional communication connection with the main circuit breaker module, the circuit adapter module and the network module; The intelligent control software system acquires the operating status data of each hardware module on the intelligent circuit breaker in real time through a preset data acquisition protocol; it monitors the operating status data of each hardware module in real time and performs multi-dimensional fault analysis based on a preset diagnostic algorithm to obtain fault type judgment value, fault location judgment value, and fault severity judgment value. The fault type judgment value, fault location judgment value, and fault severity judgment value are used to determine the fault characteristics of each hardware module and generate corresponding processing strategies that match the fault characteristics; at the same time, it receives and verifies remote control commands from user terminals or external management systems, drives the corresponding hardware modules to perform closing and opening actions, and can push alarm notifications containing core fault information in a targeted manner according to the fault level and the attributes of the receiving object. The network module is equipped with a signal transmitter at its bottom for amplifying signal transmission. The main circuit breaker module is hinged to a closing wrench for controlling the power switch at its front end. The main circuit breaker module is equipped with a power distribution module. The power distribution module is equipped with a power supply mechanism for temporary power supply at its lower end. The main circuit breaker module is equipped with an alarm mechanism for short circuit alarm.

[0006] Preferably, the power supply mechanism includes a power frame installed at the lower end of the power distribution module. A battery is installed inside the power frame. A positive power terminal is installed at one end of the inner wall of the power frame, and an electromagnet is installed at the other end of the inner wall of the power frame. A current guide plate is fixed to the other end of the electromagnet through an insulating pad. A negative power terminal that cooperates with the positive terminal of the battery is fixed to the other end of the current guide plate. A compression spring is installed on one side of the current guide plate through an insulating pad, and the other end of the compression spring is installed on one end of the inner wall of the power frame.

[0007] Preferably, the guide plate is equipped with line interfaces at both the top and bottom, and wires are connected to both of the line interfaces. The power supply frame is provided with through slots for the wires at both the top and bottom. The positive terminal of the power supply is connected to one end of the power distribution module through a conductive sheet, and the upper wire is connected to the other end of the power distribution module.

[0008] Preferably, the alarm mechanism includes an alarm module installed inside the main circuit breaker module. The front end of the alarm module is equipped with multiple LEDs of different colors. The light-emitting ends of the multiple LEDs are located on the outer side of the main circuit breaker module. A buzzer is installed at the top of the alarm module, penetrating the top of the main circuit breaker module. The positive and negative terminals of the alarm module's power supply are connected to the conductive sheet and the lower wire, respectively.

[0009] Preferably, the output end of the small motor is equipped with a worm gear via a coupling, the upper end of the worm gear is engaged with a worm wheel, a drive gear is coaxially connected to one side of the worm wheel, the front end of the drive gear is engaged with a transmission gear, the front end of the transmission gear is engaged with a sector gear, and the sector gear is fixedly connected to the hinge shaft of the closing wrench.

[0010] Preferably, the main circuit breaker module is connected to the circuit adapter modules and network modules on both sides via a Type-C cable.

[0011] Preferably, the intelligent control system specifically includes: The data acquisition module is used to acquire the operating status data of each hardware module on the smart circuit breaker in real time through a preset data acquisition protocol. The operation status monitoring module is used to monitor the operation status data of each hardware module on the smart circuit breaker in real time. It compares the collected data with preset standard parameters. If any parameter index is abnormal, it generates the corresponding abnormal parameter instruction and marks the parameter as a preliminary abnormal parameter. The fault analysis and processing module receives abnormal parameter instructions and marked preliminary abnormal parameters sent by the operation status monitoring module. Based on the preset diagnostic algorithm, it performs multi-dimensional fault analysis and outputs fault type judgment value, fault location judgment value, and fault severity judgment value. The module determines the fault characteristics of each hardware module through the above three types of judgment values, and then generates corresponding processing strategies that match the fault characteristics. At the same time, it generates a fault analysis report containing fault cause speculation and processing suggestions.

[0012] The integrated remote control and alarm push unit establishes an encrypted communication link through a network module, receives and verifies closing and opening commands sent by user terminals or external management systems, drives the small motor and main circuit breaker module to perform corresponding actions and provides real-time feedback on the execution results; at the same time, it combines fault analysis reports, fault levels, and recipient attributes to generate alarm notifications containing core fault information and pushes them to preset user terminals or monitoring platforms.

[0013] Preferably, the specific process of the operation status monitoring module is as follows: The operational status data of each hardware module is categorized and sorted, and a data classification system is established according to module type and parameter attributes. Then, each categorized operational parameter is compared with the corresponding preset standard parameter range one by one. If a parameter exceeds the upper limit of the standard range or falls below the lower limit of the standard range, it is judged as a parameter abnormality. When an abnormal parameter instruction is generated, the abnormal value, occurrence time and the hardware module identifier of the parameter are recorded simultaneously. After marking the initial abnormal parameters, the abnormal parameters are prioritized and divided into core abnormal parameters and non-core abnormal parameters according to the degree of impact of the parameters on the circuit breaker's operational safety. Core abnormal parameters and corresponding instructions are transmitted to the fault analysis and processing module first.

[0014] Preferably, the specific process of the fault analysis and processing module is as follows: The system preprocesses the received abnormal parameter commands and preliminary abnormal parameters to remove invalid and interfering data. Then, it calls a pre-defined diagnostic algorithm to match the preprocessed abnormal parameters with standard fault features in the fault feature database, calculating the similarity and converting it into a fault type determination value. Combining the hardware module's installation location information, circuit connection logic, and abnormal parameter propagation path, it generates a fault location determination value. Based on the deviation of the abnormal parameters from the standard value, the fault duration, and the potential impact on the power system, it generates a fault severity determination value. After determining the fault characteristics based on these three types of determination values, it retrieves an appropriate processing strategy from a pre-defined processing strategy library. Simultaneously, it integrates the fault characteristics, determination criteria, and processing strategies to generate a structured fault analysis report.

[0015] Preferably, the specific process of the integrated remote control and alarm push unit is as follows: The encrypted communication link established through the network module receives instructions sent by user terminals or external management systems. After encrypting and decrypting the instructions, the sender's identity and authorization and the legality of the instructions are verified. If the instruction is a closing or opening control instruction and the verification is successful, the corresponding hardware drive signal is generated and sent to the small motor and main circuit breaker module to drive them to perform the corresponding actions. During the execution of the actions, hardware operating status data is collected in real time. After the actions are completed, feedback information containing the execution result and the current equipment status is generated and sent back to the sender. If an alarm push request is triggered, the core information such as the fault type, location, and severity from the fault analysis report is extracted. The fault level is then classified based on the fault severity judgment value. A personalized alarm notification is generated according to the preset notification format and push priority of the recipient attributes (user terminal / monitoring platform). The alarm notification is pushed to the preset recipients through the network module and signal transmitter. The push status is monitored in real time. If no confirmation of receipt is received, the push is repeated at preset intervals until the reception is successful or the preset push limit is reached. A complete push log is recorded.

[0016] Compared with the prior art, the beneficial effects of the present invention are: 1. The solution employs a collaborative design between the power supply and alarm mechanisms. When the main power supply is interrupted due to a short circuit, the electromagnet loses its magnetism, compressing a spring that pushes a guide plate to connect to battery power, providing temporary power to core components such as the alarm module and intelligent control software system. The alarm module drives a multi-color LED to flash alternately and a buzzer to sound, creating a continuous audible and visual warning. This ensures that on-site personnel can quickly detect the fault even after the main power supply is interrupted, completely solving the problem of insufficient alarm continuity in traditional equipment and improving the effectiveness of fault warnings.

[0017] 2. The intelligent control software system in this solution acquires operational data from various hardware components through a data acquisition module. This data is then analyzed from multiple dimensions, including filtering and similarity matching algorithms, by the fault analysis and processing module to generate fault type, location, and severity judgment values. This accurately identifies fault characteristics and generates reports. Simultaneously, through an integrated remote control and alarm push unit, alarm notifications containing core information are pushed to users based on fault level and recipient attributes. This allows user terminals and the monitoring platform to quickly obtain critical data, enabling maintenance personnel to identify fault conditions without on-site investigation, significantly shortening response and processing time and reducing the risk of fault escalation.

[0018] 3. This solution establishes an encrypted communication link with the network module through the remote control unit of the intelligent control software system. After receiving and verifying the closing and opening commands from the user terminal or external management system, it drives a small motor to actuate the closing wrench via a worm gear and gear transmission mechanism, while simultaneously feeding back the execution result. This design eliminates the need for on-site personnel to operate, enabling remote opening after a fault and remote closing after fault resolution. This not only improves operational convenience but also meets the refined requirements of modern intelligent power systems for equipment collaborative management and remote operation and maintenance, thus broadening the application scenarios of circuit breakers.

[0019] In summary, this invention, through the deep integration of power supply mechanisms, intelligent control software systems, and hardware modules, specifically addresses the core pain points of traditional circuit breakers, such as interrupted alarms after short-circuit faults, ambiguous fault information transmission, and lack of remote intelligent control. It achieves multiple technical effects, including continuous audible and visual warnings, accurate fault analysis and targeted notification, and remote intelligent control. This significantly improves the intelligence level, safety protection performance, and ease of operation and maintenance of circuit breakers, perfectly adapting to the refined and collaborative management needs of modern smart power systems, and providing a reliable guarantee for the safe and stable operation of power systems.

Detailed Implementation

[0022] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments.

[0023] Example: See Figures 1 to 8 This invention discloses a smart circuit breaker with short-circuit alarm function, comprising a main circuit breaker module 1, a small motor 17 installed inside the main circuit breaker module 1, a circuit adapter module 2 and a network module 3 installed on both sides of the main circuit breaker module 1, and a smart control software system 22 that establishes bidirectional communication connections with the main circuit breaker module 1, the circuit adapter module 2, and the network module 3. A signal transmitter 4 for amplifying signal transmission is installed at the bottom of the network module 3. A closing wrench 5 for controlling the circuit breaker is hinged to the front end of the main circuit breaker module 1. A power distribution module 6 is installed inside the main circuit breaker module 1, and a power supply mechanism for temporary power supply is installed at the lower end of the power distribution module 6. An alarm mechanism for short-circuit alarm is also installed inside the main circuit breaker module 1.

[0024] The power supply mechanism is installed at the lower end of the power distribution module 6. Its power frame 9 is fixed to the internal mounting plate of the main circuit breaker module 1 by bolts. The battery 8 is a rechargeable lithium battery, adapted to the internal dimensions of the power frame 9, ensuring no looseness after installation. The electromagnet 11 is electrically connected to the power distribution module 6 via wires. Its adsorption surface is parallel and aligned with the corresponding surface of the guide plate 12. The insulating pad is made of high-temperature resistant insulating material and is pasted and fixed between the electromagnet 11 and the guide plate 12 to avoid conductive interference. The two ends of the compression spring are respectively fixed to the side of the guide plate 12 and the inner wall of the power frame 9 by clips. In the natural state, a slight preload is maintained to ensure that the electromagnet 11 can quickly push the guide plate 12 to move after power is cut off.

[0025] The wiring interfaces at both ends of the flow guide plate 12 adopt a pluggable structure. After the wires are fixed to the flow guide plate 12 through the interfaces, they pass through the through slots at both ends of the power supply frame 9. The inner wall of the through slots is equipped with a rubber protective sleeve to prevent wire wear. The positive terminal 10 of the power supply is bolted to the terminal of the power distribution module 6 through the conductive sheet 14. The conductive sheet 14 is made of copper to ensure stable conductivity. The upper wire is welded to another terminal of the power distribution module 6, and the lower wire is connected to the negative terminal of the alarm module 7.

[0026] The alarm module 7 of the alarm mechanism is fixed to the mounting bracket inside the main circuit breaker module 1 via a slot. Multiple different colored LEDs 15 are evenly distributed on the front panel of the alarm module 7, with their light-emitting ends corresponding to the reserved through holes on the outer side of the main circuit breaker module 1. A transparent protective cover is installed at the through hole, which does not affect the light transmission and also provides dust protection. The buzzer 16 is fixed to the upper end of the alarm module 7 by a threaded connection. Its sound-emitting end passes through the opening at the top of the main circuit breaker module 1. A sound-insulating sealing gasket is provided around the opening to reduce noise leakage interference to the internal module. The positive terminal of the alarm module 7 is electrically connected to the conductive plate 14.

[0027] The small motor 17 is fixed to the base plate inside the main circuit breaker module 1 via a motor mount. Its output end is rigidly connected to the worm gear 18 via a coupling to ensure slippage-free power transmission. Lubricant is applied to the meshing surfaces of the worm gear 18 and the worm wheel 19 to reduce transmission wear. The drive gear on one side of the worm wheel 19 is integrally molded with the worm wheel 19. The transmission gear 20 is mounted on the intermediate bracket via a rotating shaft. The sector gear 21 is fixed to the hinge shaft of the closing wrench 5 via a key connection. The meshing clearance of each gear is controlled within a preset range to ensure smooth transmission.

[0028] The main circuit breaker module 1 is connected to the circuit adapter modules 2 and network modules 3 on both sides via a Type-C cable. The Type-C interface is waterproof and is installed in the interface slot on the side of each module. The interface slot is equipped with a dust cover. When not in use, the interface can be closed to protect it and ensure the stability and durability of the connection.

[0029] The present invention also includes an intelligent control system that establishes bidirectional communication connections with the main circuit breaker module 1, the circuit adapter module 2, and the network module 3. The intelligent control software system 22 is integrated into the control chip inside the main circuit breaker module 1. Each functional module works collaboratively according to preset logic, and the specific operating flow is as follows: The data acquisition module pre-stores data acquisition protocols adapted to various hardware modules, including the on / off status acquisition protocol for the main circuit breaker module 1, the signal transmission parameter acquisition protocol for the circuit adapter module 2, the battery power and voltage acquisition protocol for the power supply mechanism, and the operating status acquisition protocol for the alarm module 7. During circuit breaker operation, the data acquisition module sends data acquisition commands to each hardware module in real time at a preset sampling frequency, receives operating status data from each hardware module, performs preliminary formatting of the data to remove redundant fields, forms a standardized data format, and then transmits it to the operating status monitoring module.

[0030] After receiving standardized data from the data acquisition module, the operation status monitoring module establishes a data classification system according to module type (main circuit breaker module 1, circuit adapter module 2, power supply mechanism, alarm module 7, etc.) and parameter attributes (voltage, current, signal strength, on / off status, etc.), storing different types of parameters from different modules into their corresponding data buffers. Subsequently, each classified operating parameter is compared one by one with a preset standard parameter range, which is stored in the system's parameter configuration library and adjusted according to the actual application scenario. If a parameter exceeds the upper limit of the standard range or falls below the lower limit, the parameter is determined to be abnormal. An abnormal parameter instruction is generated, containing the parameter name, abnormal value, occurrence time, and the identifier of the hardware module to which it belongs, and the parameter is marked as a preliminary abnormal parameter. After marking, parameters are prioritized according to their impact on the circuit breaker's operational safety. Parameters that directly affect circuit safety, such as those related to short circuits and overloads, are listed as core abnormal parameters, while other parameters are listed as non-core abnormal parameters. Core abnormal parameters and their corresponding instructions are transmitted to the fault analysis and processing module first, while non-core abnormal parameters are transmitted sequentially according to the queue order.

[0031] After receiving the abnormal parameter command and preliminary abnormal parameters from the operation status monitoring module, the fault analysis and processing module first performs data preprocessing. It then uses a moving average filtering algorithm to remove invalid data and misjudged data caused by environmental interference, retaining only valid abnormal data. This moving average filtering algorithm is suitable for stabilizing real-time circuit breaker data; its formula is... ;in Let n be the filtered effective data at time k, and n be the sliding window size. For the first The system continuously collects raw abnormal parameter data, where i is the data index within the window. Then, a preset diagnostic algorithm is invoked to match and compare the preprocessed valid abnormal parameters with standard fault features in the fault feature database. The fault feature database stores feature parameter models for various common faults such as short circuits, overloads, poor contacts, and battery depletion.

[0032] The similarity between effective anomaly parameters and each standard fault feature is calculated using the cosine similarity algorithm. The formula is Where m is the dimension of the feature parameter (such as the total number of feature dimensions such as voltage, current, temperature, etc.). The effective outlier parameters after filtering in the j-th dimension are... The j-th dimension is the standard fault characteristic parameter (retrieved from the fault characteristic database). , These are the normalized parameter values; the matching similarity S is converted into a fault type determination value. (The judgment value ranges from 0 to 1, and the closer it is to 1, the higher the matching degree.) The corresponding fault type is determined based on the fault type judgment value.

[0033] Simultaneously, by combining the installation location information of the hardware modules, the circuit connection logic, and the abnormal parameter propagation path, the source of abnormal parameters is analyzed, and a fault location determination value is generated through a weighted summation algorithm. The formula is Where q represents the total number of internal hardware modules of the circuit breaker; The position weight of the p-th hardware module is preset based on the module's connection relationship and importance in the circuit. The abnormal correlation degree of the p-th hardware module (calculated from the abnormal propagation path of the parameters, the correlation degree of the module that is the source of the abnormality is 1, and the correlation degree of the indirectly affected modules is 0~1). The value ranges from [0,1]. The closer the value is to the peak value of the weight ratio of a certain module, the higher the probability that the fault occurred in that module. Based on the magnitude of the deviation of abnormal parameters from standard values, the duration of the fault, and the potential impact on the power system, a fault severity determination value is generated using a weighted normalization algorithm. The formula is , In the formula, This is a calculated value for the unnormalized severity of the fault. This is the normalized fault severity judgment value. These are the weighting coefficients for parameter deviation magnitude, fault duration, and potential impact range, respectively. This is the standard value for this parameter. These are the maximum and minimum allowable values ​​for this parameter, respectively; t is the fault duration. The maximum allowable duration of the fault is preset; r is the potential impact range coefficient; the fault severity judgment value is matched with the preset fault severity range to classify it into minor fault, moderate fault and severe fault.

[0034] Based on fault type determination value Fault location determination value and fault severity judgment value It accurately identifies the fault characteristics of each hardware module, retrieves the corresponding processing strategy from the preset processing strategy library, and integrates the fault characteristics, judgment criteria, and processing strategies to generate a structured fault analysis report, which is then transmitted to the integrated remote control and alarm push unit.

[0035] The integrated remote control and alarm push unit establishes an encrypted communication link through network module 3, employing a symmetric encryption algorithm to encrypt communication data, ensuring data transmission security. Upon receiving instructions from user terminals or external management systems, the unit first encrypts and decrypts the instructions, extracting key information such as the operation type (closing, opening), and sender identity. It then verifies whether the sender's identity and permissions meet the preset permission level, and checks the validity of the instruction format and whether the instruction content falls within the preset operation range.

[0036] If the instruction is a closing or opening control instruction and the verification passes, a corresponding hardware drive signal is generated according to the instruction type and sent to the execution unit of the small motor 17 and the main circuit breaker module 1. After the drive signal is sent, the speed and torque of the small motor 17 and the on / off status data of the main circuit breaker module 1 are collected in real time to monitor the action execution process. After the action is completed, feedback information including the execution result (success / failure), the current equipment status (closing / opening), and the action execution time is generated and sent back to the sender through an encrypted communication link; if the verification fails, an instruction verification failure prompt message is generated, sent back to the sender, and the reason for the failure is recorded.

[0037] When a fault analysis report is received from the fault analysis and processing module, an alarm push request is triggered. Key information from the fault analysis report, such as fault type, location, severity, and handling suggestions, is extracted and combined with the fault severity judgment value. Fault severity is categorized (mild, moderate, severe). Based on the recipient's attributes (user terminal / monitoring platform), a preset notification format template is invoked. The notification format for user terminals primarily uses concise and clear text, including core fault information and operation instructions; the notification format for monitoring platforms uses structured data, including complete fault analysis report content and data identifiers.

[0038] The system prioritizes notifications based on the fault severity: severe faults are assigned the highest priority, moderate faults the medium priority, and minor faults the normal priority. Alarm notifications are pushed to preset recipients via network module 3 and signal transmitter 4. Signal transmitter 4 enhances the signal transmission strength and coverage of network module 3, ensuring rapid notification delivery. The system monitors the push status in real time. If no confirmation of receipt is received from the recipient within a preset time, the push is repeated at preset intervals (e.g., 1 minute for severe faults, 3 minutes for moderate faults, and 5 minutes for minor faults) until confirmation of receipt is received or the preset push limit is reached (e.g., a maximum of 5 pushes). A complete push log is recorded, including push time, recipient, and push result.

[0039] The overall workflow of the smart circuit breaker with short-circuit alarm function proposed in this invention is as follows: When this invention is used, the intelligent control software system 22 runs continuously, and each module works collaboratively according to the above process. The specific overall workflow is as follows: Normal operating state: After the circuit breaker is connected to the circuit, the power distribution module 6 provides stable power to each hardware module and the intelligent control software system 22. The electromagnet 11 is energized to generate magnetic force, attracting the current guide plate 12 to compress the compression spring. The negative terminal 13 of the power supply is separated from the positive terminal of the battery 8, and the power supply mechanism is in standby state. The data acquisition module collects the operating status data of each hardware module in real time, and the operating status monitoring module continuously compares the parameters. When there are no abnormalities, the circuit breaker remains in the normal closed state, and the intelligent control software system 22 updates and stores the operating status data at a preset frequency.

[0040] When a short circuit occurs: When a short circuit occurs in the circuit, the short circuit detection unit inside the main circuit breaker module 1 responds quickly and triggers the tripping mechanism, interrupting the power supply to the power distribution module 6. At this time, the electromagnet 11 loses its magnetic force due to the power failure, and the attraction force on the guide plate 12 disappears. Under the elastic restoring force of the compression spring, the guide plate 12 drives the negative terminal of the power supply 13 to move towards the battery 8 until the negative terminal of the power supply 13 is in close contact with the positive terminal of the battery 8. At the same time, the positive terminal of the power supply 10 remains in contact with the negative terminal of the battery 8. The power supply mechanism is activated, and the battery 8 begins to provide temporary power to the small motor 17, alarm mechanism, network module 3, signal transmitter 4, and intelligent control software system 22.

[0041] After the alarm mechanism is powered, the alarm module 7 controls multiple different colored carousel lights 15 to flash alternately at a preset frequency, and the buzzer 16 emits a high-decibel alarm sound, alerting nearby personnel from both visual and auditory perspectives.

[0042] With the support of temporary power supply, the intelligent control software system 22 collects abnormal data corresponding to short circuit faults through the data acquisition module. The operation status monitoring module quickly determines the core abnormal parameters and transmits them to the fault analysis and processing module. After data preprocessing and feature matching, the fault analysis and processing module generates a fault analysis report with the fault type being short circuit, the fault location being clearly identified, and the severity being severe. The report is then transmitted to the integrated unit for remote control and alarm push.

[0043] The integrated remote control and alarm push unit combines fault analysis reports to generate alarm notifications that meet the format requirements of user terminals and monitoring platforms. These notifications are then pushed to preset recipients via network module 3 and signal transmitter 4. At the same time, the highest push priority is set according to the fault level to ensure that relevant personnel receive fault information in a timely manner.

[0044] If the user sends a trip confirmation command through the terminal, after the remote control and alarm push integrated unit verifies the command, it sends a drive signal to the small motor 17. The small motor 17 runs and drives the worm gear 18 to rotate through the coupling. The worm gear 18 meshes with the worm wheel 19, which drives the drive gear on one side of the worm wheel 19 to rotate. The drive gear meshes with the transmission gear 20, which in turn drives the transmission gear 20 to rotate. The transmission gear 20 meshes with the sector gear 21. Finally, the rotation of the sector gear 21 drives the closing wrench 5 to automatically complete the tripping action, quickly cut off the fault circuit, and prevent the accident from escalating.

[0045] After troubleshooting: When the user or maintenance personnel troubleshoots the problem and the main power supply is restored to normal, the power distribution module 6 regains stable power. The electromagnet 11 is energized and generates magnetic force, which overcomes the elastic force of the compression spring and attracts the guide plate 12 to move towards the electromagnet 11. The negative terminal 13 of the power supply is separated from the positive terminal of the battery 8, the power supply mechanism stops working, and the battery 8 enters the charging mode under the management of the power distribution module 6, preparing for emergency power supply in case of the next possible fault.

[0046] Users can send a closing command via the terminal. After the remote control and alarm push integrated unit verifies the command, it drives the small motor 17 to rotate in reverse, which in turn drives the closing wrench 5 through the transmission mechanism to complete the closing action, restoring the circuit breaker to normal operation. The intelligent control software system 22 records complete data of the fault handling process, including the fault occurrence time, handling time, fault analysis results, operation commands, etc., and uploads the data to the external intelligent power management system for subsequent traceability and statistical analysis.

[0047] The above description is only a preferred embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in the present invention, based on the technical solution and inventive concept of the present invention, should be covered within the scope of protection of the present invention.

7. A smart circuit breaker with short-circuit alarm function according to claim 1, characterized in that: The intelligent control system specifically includes: The data acquisition module is used to acquire the operating status data of each hardware module on the smart circuit breaker in real time through a preset data acquisition protocol. The operation status monitoring module is used to monitor the operation status data of each hardware module on the smart circuit breaker in real time. It compares the collected data with preset standard parameters. If any parameter index is abnormal, it generates the corresponding abnormal parameter instruction and marks the parameter as a preliminary abnormal parameter. The fault analysis and processing module receives abnormal parameter instructions and marked preliminary abnormal parameters sent by the operation status monitoring module. Based on the preset diagnostic algorithm, it performs multi-dimensional fault analysis and outputs fault type judgment value, fault location judgment value, and fault severity judgment value. The module determines the fault characteristics of each hardware module through the above three types of judgment values, and then generates corresponding processing strategies that match the fault characteristics. At the same time, it generates a fault analysis report containing fault cause speculation and processing suggestions. The integrated remote control and alarm push unit establishes an encrypted communication link through the network module (3), receives and verifies the closing and opening commands sent by the user terminal or external management system, drives the small motor (17) and the main circuit breaker module (1) to perform corresponding actions and provides real-time feedback on the execution results; at the same time, it combines the fault analysis report and fault level, and the attributes of the receiving object to generate an alarm notification containing the core fault information and pushes it to the preset user terminal or monitoring platform.

A smart circuit breaker with short-circuit alarm function according to claim 7, characterized in that: The specific process of the operation status monitoring module is as follows: The operating status data of each hardware module is classified and sorted, and a data classification system is established according to module type and parameter attributes. Then, each classified operating parameter is compared with the corresponding preset standard parameter range one by one. If the parameter exceeds the upper limit of the standard range or is lower than the lower limit of the standard range, it is judged as a parameter abnormality. When an abnormal parameter instruction is generated, the abnormal value, occurrence time and the hardware module identifier of the parameter are recorded simultaneously. After marking the initial abnormal parameters, the abnormal parameters are prioritized and divided into core abnormal parameters and non-core abnormal parameters according to the degree of impact of the parameters on the safe operation of the circuit breaker. Core abnormal parameters and corresponding instructions are transmitted to the fault analysis and processing module first.

9. A smart circuit breaker with short-circuit alarm function according to claim 7, characterized in that: The specific process of the fault analysis and processing module is as follows: The received abnormal parameter commands and preliminary abnormal parameters are preprocessed to remove invalid and interference data; then the preset diagnostic algorithm is called to match and compare the preprocessed abnormal parameters with the standard fault features in the fault feature database, calculate the matching similarity and convert it into a fault type judgment value. By combining the installation location information of the hardware module, the circuit connection logic, and the abnormal propagation path of the parameters, a fault location determination value is generated; Based on the magnitude of the deviation of abnormal parameters from the standard value, the duration of the fault, and the potential impact on the power system, a fault severity judgment value is generated. After determining the fault characteristics based on the three judgment values, an appropriate processing strategy is retrieved from the preset processing strategy library. At the same time, the fault characteristics, judgment basis, and processing strategy are integrated to generate a structured fault analysis report.

10. A smart circuit breaker with short-circuit alarm function according to claim 7, characterized in that: The specific process of the integrated remote control and alarm push unit is as follows: The encrypted communication link established by the network module (3) receives instructions sent by user terminals or external management systems. After encrypting and decrypting the instructions, the identity and authority of the sender and the legality of the instructions are verified. If the instruction is a closing or opening control instruction and the verification is successful, the corresponding hardware drive signal is generated and sent to the small motor (17) and the main circuit breaker module (1) to drive them to perform corresponding actions. During the execution of the action, the hardware operation status data is collected in real time. After the action is completed, feedback information containing the execution result and the current equipment status is generated and sent back to the sender. If an alarm push request is triggered, the core information such as the fault type, location, and severity in the fault analysis report is extracted, and the fault level is classified in combination with the fault severity judgment value. Based on the preset notification format and push priority of the recipient attributes (user terminal / monitoring platform), a personalized alarm notification is generated. The alarm notification is pushed to the preset receiving object through the network module (3) and the signal transmitter (4), and the push status is monitored in real time. If no receiving confirmation feedback is received, the push is repeated at the preset interval until the feedback is successful or the preset push number limit is reached, and a complete push log is recorded.
