The 10KV line fault precise positioning device mainly achieves precise fault positioning through the following methods:
Sensor collects fault signals
Sensors are installed on the ABC three-phase lines of the 10kV overhead power line, with one sensor installed on each phase and one set installed on each pole at intervals. These sensors can detect parameters such as ground induced voltage, load current, and grounding capacitance current on the overhead line section.
data acquisition and processing
The data acquisition module converts the fault signals collected by the sensors into electrical signals, and the data processing unit processes and analyzes these electrical signals. Through certain criteria and algorithms, the device can determine whether a short circuit or grounding fault has occurred in the circuit and issue an alarm signal.
Wireless communication transmission
The device is equipped with a built-in wireless communication module. When a fault is detected, the fault information is displayed on site through the fault indicator flipping or emitting light, and the fault information is transmitted to the backend monitoring platform through wireless radio frequency. The monitoring platform can receive and analyze this data in real-time, providing accurate information on fault points for line management personnel.
Fault indication and alarm
When a fault is detected, the fault indicator will display the fault information by flipping or emitting light, which can be observed within a 360 ° range. When flipping, the display panel adopts night vision reflective technology. In addition, the device also has on-site and remote alarm functions, which can be used to achieve on-site management even without networking; Through cloud servers, it is possible to remotely monitor data from any collection terminal and obtain real-time alarm information.
Data rationality check and analysis
The device has the function of checking and analyzing the rationality of data, which can automatically identify and eliminate interference data, ensuring the accuracy and reliability of collected data. This helps to improve the accuracy and reliability of fault location.
Automatic reset and backup power supply
The fault indicator probe has the function of delayed automatic reset or remote reset, and the automatic reset time can be set by the user or before leaving the factory. In addition, the device is equipped with solar panels to charge the backup power supply, which can maintain continuous operation of the communication terminal for 15 days without the need for additional energy.
Artificial intelligence fault recognition
The core module based on artificial intelligence deep learning algorithm can automatically and quickly identify fault types, and assist distribution network operation and inspection personnel in analyzing the causes of faults and warning of hidden dangers. The fault recognition program has a recognition rate of over 95% for fault types and a fault recognition time of less than 5 minutes.
Through the comprehensive application of various technologies and methods mentioned above, the 10KV line fault precise positioning device can achieve fast and accurate positioning of line faults, providing strong guarantees for the safe and stable operation of the power system.
