In the power transmission system, high-voltage cables play a crucial role, and their safe and stable operation is essential for ensuring the continuity and reliability of power supply. However, cable faults occur from time to time, and how to quickly and accurately locate the fault point has become a major challenge in the field of power maintenance. Although traditional high-voltage cable fault location methods can play a role to some extent, they have many shortcomings compared to modern high-voltage cable fault precise location systems. The following will be combined with the Dunheng brandDH-ZWGZ100A precise fault location system for high-voltage cables, detailing its significant advantages compared to traditional methods.

1、 Significant improvement in positioning accuracy

Traditional high-voltage cable fault location methods, such as impedance method, acoustic measurement method, etc., are often limited by measurement technology and environmental factors, and the positioning accuracy is often difficult to guarantee, with errors that may reach tens or even hundreds of meters. This not only increases the difficulty and time of troubleshooting, but may also cause secondary damage to the cables. And DunhengDH-ZWGZ100The precision positioning system for high-voltage cable faults, based on advanced technologies such as 100Mbps high-speed sampling, Beidou high-precision timing, and precise calibration of signal phase errors, has achieved positioning accuracy less than5Excellent performance of rice. The improvement of this accuracy enables the fault point to be quickly and accurately locked, greatly reducing the troubleshooting time and improving the efficiency of power maintenance.

2、 High degree of intelligence

Traditional methods often require manual analysis and judgment of a large amount of data in the process of fault location, which is not only inefficient but also susceptible to human factors. And DunhengDH-ZWGZ100The system adopts the core module of artificial intelligence deep learning algorithm, which can automatically and quickly locate faults, and assist cable operation and inspection personnel in fault cause analysis and prediction. This intelligent processing method not only improves the accuracy and efficiency of fault location, but also reduces the workload of operation and inspection personnel.

3、 Real time monitoring and warning function

Traditional methods usually can only locate faults after they occur, and cannot achieve real-time monitoring and early warning. And DunhengDH-ZWGZ100The type system collects real-time cable fault traveling wave signals and fault power frequency signals through the cable monitoring terminal host, and uploads them to the monitoring platform. Once an abnormality is detected, the system will immediately push the operation and maintenance personnel through an alert SMS. The operation and maintenance personnel can use mobile SMS andwebThe client can view relevant information in real-time. This real-time monitoring and warning function enables power maintenance personnel to take measures before or in the early stages of faults, effectively preventing the expansion of faults, reducing power outage time and economic losses.

4、 Convenient data communication and remote management

Traditional methods have many inconveniences in data transmission and management, such as the need for manual on-site data recording and difficulty in remote management. And DunhengDH-ZWGZ100The system adopts4GWireless communication enables remote transmission and communication of local data. Operations personnel can configure parameters and perform remote upgrades on terminals through the cloud platform, without the need for on-site operations, greatly improving management efficiency and convenience.

5、 Strong adaptability and diverse power supply methods

Traditional methods may be limited by environmental and power supply conditions during application. And DunhengDH-ZWGZ100To adapt to different application scenarios, the cable monitoring host can choose from mains power, solar powerCTMultiple power supply methods such as electricity supply are available to meet on-site installation requirements. This diversified power supply method enables the system to operate stably in various complex environments, improving its adaptability and reliability.

Dunheng brandDH-ZWGZ100Compared with traditional methods, the precision positioning system for high-voltage cable faults has shown significant advantages in positioning accuracy, intelligence level, real-time monitoring and warning functions, convenience of data communication and remote management, adaptability, and diversity of power supply methods. These advantages not only improve the efficiency and accuracy of power maintenance, but also reduce operation and maintenance costs and power outage time, providing strong guarantees for the safe and stable operation of the power transmission system.
