Description

Technical Field

[0001] This utility model relates to the field of power system technology, and in particular to an intelligent diagnostic device for power system faults. Background Technology

[0002] In the field of power system technology, the safe and stable operation of the power system is crucial to ensuring the normal supply of electricity for social production and daily life. As a complex and vast system, the power system comprises power generation, supply (including transmission, substation, and distribution), power consumption facilities, and secondary facilities such as regulation and control, relay protection and safety automation devices, metering devices, dispatch automation, and power communication, forming a unified whole. However, in actual operation, power system faults are unavoidable due to various reasons such as equipment aging, environmental factors, and improper operation. These faults not only affect the continuity and reliability of power supply but may also damage equipment and even trigger safety accidents.

[0003] Currently, various solutions for diagnosing power system faults have been proposed and applied. For example, CN222580193U discloses an electrical equipment fault diagnosis device based on intelligent sensors. This device integrates core components such as intelligent sensor units, central processing units, monitoring units, and storage units to achieve real-time monitoring and fault diagnosis of electrical equipment operating parameters. Its technical principle lies in using intelligent sensor units (including vibration sensors, temperature sensors, current sensors, voltage sensors, and humidity sensors) to detect various operating parameters of electrical equipment and transmitting this data to the central processing unit for real-time matching and analysis. By comparing this data with a preset data model, abnormal data is identified, and fault diagnosis is achieved.

[0004] However, while the aforementioned technical solutions improve the efficiency and accuracy of power system fault diagnosis to some extent, they still have significant problems and shortcomings. Specifically, the device mainly relies on existing fault data models for matching and diagnosis, and these models are usually built based on common and well-known fault types. Therefore, when faced with uncommon faults or novel faults appearing for the first time, the device often fails to effectively detect and diagnose them, resulting in a significant reduction in the timeliness and accuracy of fault handling. This limitation not only reduces the practicality of the device but may also pose a potential threat to the safe and stable operation of the power system.

[0005] Furthermore, the aforementioned technical solutions lack effective emergency response measures in emergency situations such as fires caused by major electrical equipment malfunctions. Although the device is equipped with monitoring and storage units capable of recording and transmitting fault data, these functions are clearly insufficient to meet the need to promptly prevent the spread and development of disasters during a fire.

[0006] Therefore, developing an intelligent fault diagnosis device for power systems that can continuously update the database, expand the scope of fault diagnosis, and has efficient emergency handling functions is of great significance for improving the operating efficiency and safety of power systems and ensuring the normal electricity use for social production and life. Utility Model Content

[0007] The technical problem this invention aims to solve is to provide an intelligent diagnostic device for power system faults, addressing specific technical issues in the field of power system fault diagnosis. Specifically, existing power system fault diagnosis devices primarily rely on existing fault data models for matching and diagnosis, resulting in a lack of effective detection and diagnosis capabilities for uncommon faults and novel faults appearing for the first time, thus limiting their practicality. Furthermore, existing technologies lack effective emergency response measures when electrical equipment experiences fires due to significant faults.

[0008] To solve the above-mentioned technical problems, the present invention adopts the following technical solution:

[0009] This utility model designs an intelligent diagnostic device for power system faults, the structure and technical solution of which are as follows:

[0010] Firstly, regarding the main body of the device, this utility model adopts a robust and durable shell design, with a display screen and button area on the front. The display screen is used to display fault diagnosis results and system status in real time, while the buttons facilitate on-site operators to input parameter settings and fault handling commands.

[0011] Secondly, the data acquisition unit, as the core of this device, integrates various high-precision sensors, including voltage / current sensors, vibration sensors, semiconductor gas sensors, temperature sensors, humidity sensors, and infrared thermal imagers. These sensors can comprehensively monitor the operating status of electrical equipment, and collect key data such as voltage, current, vibration, gas composition, temperature, humidity, and hot spot locations in real time, providing accurate basis for subsequent fault diagnosis.

[0012] The data processing unit serves as the intelligent analysis center of the device, comprising a central processing unit (CPU), an intelligent control module, a data storage module, a GPS positioning module, and a GPRS wireless communication module. The CPU receives and analyzes data transmitted from the acquisition unit, comparing it with the fault data model in the data storage module to achieve intelligent fault diagnosis. The intelligent control module controls the operation of various electronic components within the device, including adjusting sensor operating states, scheduling data transmission, and activating emergency response devices. The GPS positioning module determines the specific location of the fault, while the GPRS wireless communication module enables communication with external terminals, ensuring that fault diagnosis results and system status are transmitted in real-time to the remote monitoring center or the operator's mobile device.

[0013] Furthermore, to continuously optimize and improve the fault diagnosis capabilities of this device, a data update unit is also designed. This unit includes a PC host, an enterprise database, and a network data set, allowing engineers to manually input fault data, construct new fault data models, and obtain case data models shared by others on the Internet, thereby continuously expanding the scope of fault diagnosis and improving the accuracy and comprehensiveness of diagnosis.

[0014] Finally, in response to potential fires involving electrical equipment, this invention includes a specially designed emergency response device. This unit comprises a rotating block, a nozzle, a spraying assembly, an electric actuator, and a steering assembly. It can be rapidly activated upon detecting an overheated area, spraying extinguishing agent towards the fire source to effectively prevent the fire from spreading and escalating, thus enhancing the overall safety of the system.

[0015] The intelligent diagnostic device for power system faults provided by this utility model has the following beneficial effects:

[0016] 1. This utility model effectively solves the problems of existing power system fault diagnosis devices relying on existing fault data models for matching and diagnosis, lacking effective detection and diagnosis capabilities for uncommon and novel faults, and lacking effective emergency handling measures when electrical equipment catches fire. It successfully overcomes these limitations, improves the accuracy and comprehensiveness of power system fault diagnosis, and enhances the system's emergency response capabilities.

[0017] 2. This utility model achieves continuous database updates through multiple methods. On the one hand, when a corresponding fault model cannot be found, a signal can be sent to the PC to compare it with the data model in the enterprise database or to allow engineers to query in the network dataset. After finding the corresponding fault information, a fault handling method is constructed, and the fault data model is stored in the enterprise database. On the other hand, the data update unit can not only manually input fault data through the PC host, but also connect to the enterprise database and the network dataset to aggregate fault data models from multiple sources. This continuously broadens the scope of fault diagnosis and increases the practicality of the device.

[0018] 3. This utility model integrates a data processing unit, an acquisition unit, an emergency handling device, and a data update unit into one unit to form a complete intelligent fault diagnosis and emergency handling system for power systems, achieving integrated operation and improving fault handling efficiency.

[0019] 4. The unique design of the rotating block, nozzle, electric push rod, and steering assembly in the emergency response device of this utility model allows for precise adjustment of the nozzle orientation through the cooperation of the drive motor, transmission gear, and fixed gear ring. The electric push rod is hinged to the nozzle to flexibly adjust the tilt angle. When a fire occurs in outdoor electrical equipment, in conjunction with the detection of an infrared thermal imager, the extinguishing agent can be quickly and accurately sprayed onto the overheated spot of the electrical equipment, effectively preventing the expansion and development of the disaster and improving the safety and stability of the device.

[0020] 5. After receiving data from the acquisition unit, the data processing unit of this utility model performs intelligent diagnosis. If a fault is detected, it immediately sends a start signal to the emergency handling device to achieve collaborative work, prevent the fault from escalating further, and ensure the safe and stable operation of the power system.

[0021] 6. By integrating multiple sensors, this utility model can comprehensively and accurately monitor the operation of electrical equipment, reduce the risk of misjudgment and omission, and improve the accuracy of fault diagnosis.

[0022] 7. The combined use of the GPS positioning module and GPRS wireless communication module of this utility model enables the device to send fault location signals to external terminals in real time, facilitating rapid response and fault handling.

[0023] 8. The comprehensive data update system of this utility model makes full use of internal enterprise resources and Internet shared data to continuously update and improve the fault data model, so that the fault diagnosis capability of the device is continuously improved with the accumulation of data, bringing new technological breakthroughs and innovations to the field of power system fault diagnosis, and has high practicality and application value.

Rather, it is an improvement to the combination and connection between the modules, which is explained here.

[0054] The working process of the intelligent diagnostic device for power system faults described above is as follows:

[0055] When the intelligent diagnostic device for power system faults is used, it can monitor the operation of electrical equipment through the various detection components set in the acquisition unit 3, and transmit the data during the detection process to the central processing unit 21 in the data processing unit 2. The central processing unit 21 can determine whether the electrical equipment has a fault by comparing the previous data records in the data storage module 23. If the data is abnormal, it indicates that a fault has occurred.

[0056] When a fault occurs, the central processing unit 21 can compare the fault occurrence data with the fault data model stored in the data storage module 23 to diagnose the fault, so that the fault can be processed according to the processing method in the fault data model based on the diagnosis results.

[0057] If the fault data cannot be successfully matched with the data model in the data storage module 23, the fault data is transmitted to the staff's PC host 51 via the GPRS wireless communication module 25. This allows engineers to construct the fault data model and processing method based on their own experience and the query results in the enterprise database 52 and network data set 53, and record the fault data model. This will help to continuously expand the scope of fault identification and processing while ensuring fault handling, and gradually reduce the types of faults that the device cannot handle.

[0058] In addition, if a fire is caused by a fault in outdoor electrical equipment and staff cannot arrive in time, the data processing unit 2 can be combined with the infrared thermal imager 36 to detect hot spots and control the operation of the electric push rod 43 and the drive motor 441. The operation of the electric push rod 43 can drive the nozzle 42 in the emergency treatment device 4 to rotate, so as to adjust the tilt of the nozzle 42. The operation of the drive motor 441 can drive the transmission gear 442 to move on the fixed gear ring 443, thereby driving the rotating block 41 to rotate, thus changing the orientation of the nozzle 42.

[0059] When the nozzle 42 is adjusted to face the overheated spot of the electrical equipment, the pump 452 can be controlled to extract the extinguishing agent in the storage chamber 451 and deliver it to the nozzle 42, so that the extinguishing agent can be sprayed towards the overheated spot to achieve the effect of timely fire extinguishing and effectively hinder the development of the fire.

[0073] Nozzle 42: It is rotatably connected to the top of rotating block 41 via a rotating shaft. A torsion spring is sleeved on the rotating shaft to keep the nozzle 42 in its initial position when no external force is applied. The nozzle 42 can rotate around the rotating shaft to adjust the tilt angle so as to accurately align with the hot spot of the electrical equipment.

[0074] Electric actuator 43: Rotatably connected to the top of rotating block 41 and hinged to nozzle 42. When the data processing unit detects a fault and issues a start signal, the electric actuator 43 extends and retracts according to the signal, driving nozzle 42 to rotate around the rotating shaft, thereby adjusting the tilt of nozzle 42;

Since the transmission gear 442 meshes with the fixed gear ring 443, the rotating block 41 rotates in the horizontal direction, thereby adjusting the orientation of the nozzle 42 so that the nozzle 42 can be accurately aligned with the hot spot of the electrical equipment.

[0076] The spray assembly 45 includes a storage chamber 451, a pump 452, and a delivery hose 453.

Engineers can manually input relevant fault data, including fault symptoms, handling processes, and results, through the PC host 51 to build new fault data models. The enterprise database 52 stores data models of unconventional faults, which the PC host 51 can access to update the fault data models in the data storage module. The network dataset 53 aggregates case data models shared by others on the Internet, providing the PC host 51 with a wider range of references and promoting the updating and improvement of fault data models.

[0080] III. Work Process

[0081] The data acquisition unit 3 monitors the operating parameters of the electrical equipment in real time and transmits the data to the data processing unit 2. The central processing unit 21 of the data processing unit 2 analyzes the data and compares it with the fault data model in the data storage module 23. If no fault is detected, monitoring continues. If a fault is detected, the intelligent control module 22 controls the emergency response device 4 to start. First, the drive motor 441 of the steering assembly 44 operates to adjust the orientation of the nozzle 42. At the same time, the electric actuator 43 moves to adjust the tilt of the nozzle 42 so that the nozzle 42 is accurately aimed at the hot spot. Then, the pump 452 of the spraying assembly 45 extracts the extinguishing agent from the storage chamber 451 and delivers it to the nozzle 42 through the guide hose 453. The nozzle 42 sprays the extinguishing agent onto the hot spot. Meanwhile, the GPS positioning module 24 sends a positioning signal, and the GPRS wireless communication module 25 transmits the fault diagnosis results and positioning signal to the remote monitoring center or the operator's mobile device for timely fault handling.

[0082] In addition, the data update unit 5 can update the fault data model in the data storage module 23 at any time. Engineers can manually input fault data through the PC host 51, the enterprise database 52 provides data models for unconventional faults, and the network data set 53 provides case data models shared by others on the Internet, continuously expanding the scope of fault diagnosis and improving the accuracy and comprehensiveness of diagnosis.

[0087] The rotating block 41 of the emergency response device 4 is inserted into the groove at the top of the housing 11, and its range of motion is limited by the limiting ring 411. The nozzle 42 at the top of the rotating block 41 can rotate around the rotating connection point. The electric push rod 43 is hinged to the nozzle 42 and is used to adjust the tilt angle of the nozzle 42. The drive motor 441 of the steering assembly 44 is installed inside the rotating block 41. The transmission gear 442 at the output shaft end of the motor meshes with the fixed gear ring 443, which can drive the rotating block 41 to rotate, thereby adjusting the orientation of the nozzle 42. The storage chamber 451 of the spray assembly 45 stores the extinguishing agent. The pump 452 extracts the extinguishing agent and delivers it to the nozzle 42 through the guide hose 453.

[0088] The PC host 51 of the data update unit 5 is connected to the data storage module 2, allowing engineers to manually input fault data via the PC host 51. The PC host 51 is also connected to the enterprise database 52 and the network data set 53. The enterprise database 52 stores data models of unconventional faults, while the network data set 53 aggregates case data models shared by others on the Internet, which are used to update the fault data models in the data storage module 23.

[0089] Under normal operating conditions, the data acquisition unit 3 continuously collects data from the electrical equipment and transmits it to the data processing unit 2. The central processing unit 21 analyzes the data and compares it with the fault data model in the data storage module 23. If no fault is found, the system continues monitoring; if a fault is detected, the intelligent control module 22 immediately activates the emergency response device 4. First, based on the fault location information, the intelligent control module 22 controls the drive motor 441 to rotate. Through the meshing of the transmission gear 442 and the fixed gear ring 443, the rotating block 41 rotates, adjusting the orientation of the nozzle 42. Simultaneously, it controls the extension and retraction of the electric actuator 43 to adjust the tilt angle of the nozzle 42, ensuring that the nozzle 42 is accurately aligned with the overheated spot. Then, it controls the pump 452 to operate, extracting the extinguishing agent from the storage chamber 451 and delivering it to the nozzle 42 via the guide hose 453, spraying it towards the overheated spot for fire extinguishing. At the same time, the GPS positioning module 24 sends the location signal of the faulty equipment, and the GPRS wireless communication module 25 transmits the fault diagnosis results and location information to the remote monitoring center or the operator's mobile device for timely fault handling.
