The safety and stability of high-voltage cables are crucial in the power system. Once a cable failure occurs, quickly and accurately locating the fault point is of great significance for reducing power outage time and ensuring power supply. This article will provide a detailed introduction to the use of the high-voltage cable fault precise positioning system, helping cable operators better grasp this tool and improve the efficiency of fault handling.
1、 System Introduction
The high-voltage cable fault precise positioning system is a tool for precise fault positioning and identification applied to cable lines with voltage levels of 35-500kV. The system is based on advanced technologies such as 100Mbps high-speed sampling, Beidou high-precision timing, and precise calibration of signal phase errors, combined with artificial intelligence deep learning algorithms, to achieve high-precision positioning and intelligent recognition of cable faults.
2、 Usage method
1. System installation and configuration
Install monitoring terminalInstall monitoring terminal hosts at both ends of the cable line to ensure a good connection between the host and the cable, and connect the power supply.
Configure system parametersConfigure parameters for monitoring terminals, including sampling rate, communication method, fault identification threshold, etc., through cloud platforms or on-site settings.
Check the system statusAfter the system installation and configuration are completed, check the online status and data transmission of each monitoring terminal to ensure the normal operation of the system.
2. Real time monitoring and fault warning
real-time monitoringThe system collects real-time cable fault traveling wave signals and fault power frequency signals through monitoring terminals, and uploads the data to the monitoring platform.
Fault WarningWhen the system detects abnormal signals in the cable, it will automatically trigger a fault warning mechanism and send alarm information to the operation and maintenance personnel through SMS or web client.
3. Fault location and identification
Receive alarm informationAfter receiving the fault warning information, the operation and maintenance personnel should immediately log in to the monitoring platform to view detailed information.
fault localizationUsing the fault location function provided by the system, the distance from the fault point to the two end devices is calculated based on the traveling wave signals and time difference information collected by the monitoring terminal, in order to determine the location of the fault point.
Fault identificationThe system uses intelligent deep learning algorithms to identify fault types, and operation and maintenance personnel can determine the cause of the fault based on the identification results and take corresponding measures.
4. Data analysis and report generation
data analysisOperations personnel can conduct statistical analysis on historical fault data to understand the patterns, causes, and distribution of faults, providing reference for the maintenance and management of cable lines.
Report GenerationThe system supports automatic generation of fault analysis reports, including fault location, type, handling measures, and suggestions, making it convenient for operation and maintenance personnel to record and report.
3、 Precautions
When using a high-voltage cable fault precise positioning system, it is necessary to ensure that the system is installed correctly and configured reasonably to avoid false alarms or omissions.
Operations personnel should be familiar with the operating procedures and functional characteristics of the system, so that they can quickly respond and handle faults when they occur.
The system should be regularly maintained and upgraded to ensure its stability and reliability in performance.
In summary, the high-voltage cable fault precise positioning system is an efficient and accurate tool for cable fault location. By using the system correctly, the operational reliability and safety of cable lines can be greatly improved, providing strong support for the stable operation of the power system.
