The cable fault testerunder Wuhan UHV can help many power workers to conduct various power tests more conveniently.
The measures to accelerate cable fault repair are multifaceted, aimed at improving the accuracy of fault location, accelerating repair speed, and minimizing the impact on the power grid and users. Here are some specific measures:
1、 Establish an efficient fault repair command system
Establish a fault repair command center: Based on the number of cable faults, a dedicated fault repair command center or dispatch center can be established to be responsible for the repair command and coordination work of various departments.
Provide reliable communication equipment: Ensure that the command center can timely obtain repair information and maintain smooth communication with the repair site, so that the material and logistics departments can timely understand the situation of the repair site.
2、 Develop standardized emergency repair procedures
Develop standardized emergency repair software packages: clarify the standard process of emergency repair and the work standards of each department, and improve the standardization and efficiency of repair work.
Equip a skilled repair team: Establish a 24-hour repair duty system to ensure quick response and carry out repair work upon receiving repair instructions.
3、 Adopting advanced fault location technology
By using fault location instruments such as Time Domain Reflection (TDR), Cable Fault Prediction and Location System (CFL), etc., the impedance and reflection characteristics of cable fault points can be measured to quickly and accurately locate the location of the fault.
Introducing digital diagnostic methods, such as cable fault waveform analysis, voltage pulse method, etc., to analyze and judge the detected abnormal signals, accurately identify the type of fault.
4、 Prepare for maintenance
Prepare maintenance tools and spare parts in advance: Based on the type and location of the fault, prepare the necessary maintenance tools and spare parts in advance to ensure efficient maintenance work.
Strengthen personnel training: Improve the professional skills and ability of maintenance personnel to respond to emergencies, ensuring that they can quickly and accurately handle cable faults.
5、 Introducing automation and intelligence technologies
Robot inspection and repair: Utilizing robot inspection technology combined with cable monitoring data to achieve rapid positioning of cable faults. Meanwhile, robots can work in hazardous environments, reducing the risk of human injury and improving repair efficiency.
Intelligent repair system: Combining robot technology and self-healing materials, it realizes automatic detection and intelligent repair of cable faults, improving the efficiency and reliability of cable maintenance.
6、 Improve basic information and material support
Improve basic information: Ensure that the basic information of cables and channels (especially channel position information and joint position information) is accurate and accurate, providing support for quickly locating faults.
Provide sufficient accident spare parts: Ensure timely access to necessary spare parts and materials during the repair process, and shorten the repair time.
