In the power system,35kVThe collection line plays an important role in power transmission, and its stable operation directly affects the reliability and safety of power supply. However, cable faults occur from time to time, and traditional troubleshooting methods are inefficient and inaccurate.35kVThe emergence of fault location devices for collection line cables provides an efficient and accurate solution to this problem.

Widely applicable scenarios

35kVThe fault location device for collection line cables is widely used in10kV - 35kVDistribution network lines with voltage levels. Whether it is the main or branch lines of the distribution network, as long as there is a need for cable fault location and identification, this device can play an important role. In the urban power supply network, it can help maintenance personnel quickly locate the fault points of underground cables; In remote mountainous areas or wilderness, troubleshooting of overhead power lines is equally adept, greatly reducing the time for fault repair and minimizing the scope and duration of power outages.

Outstanding advantages and significant results

High precision fault location

This device can quickly and accurately locate faults on the main and branch lines of the distribution network by installing mainline positioning devices and section positioning devices respectively. Its fault location accuracy is less than100Compared to traditional methods, Mi greatly improves the accuracy of positioning, allowing operation and maintenance personnel to quickly locate the fault point and carry out repairs.

Efficient fault identification

The fault recognition program using artificial intelligence deep learning algorithms is a major highlight of this device. It has a high recognition rate for fault types95%Above, and the fault identification time is less than5minute This efficient identification capability enables operation and maintenance personnel to quickly understand the nature of faults, develop targeted maintenance strategies, and improve fault handling efficiency.

Multi functional monitoring

In addition to fault location and identification, the device also has multiple monitoring functions. It can accurately record real-time fault current and traveling wave current, providing high-quality data support for fault analysis; Capable of real-time monitoring of power quality parameters such as current, frequency, and harmonics at installation points, and quickly alerting for situations exceeding threshold ranges. It can also focus on monitoring overloaded and overloaded lines to detect potential hazards in advance; At the same time, it can monitor environmental parameters such as temperature, sag, and dancing of overhead wires in real time, ensuring the safe operation of the line in all aspects.

Convenient remote communication

The distribution network monitoring terminal adopts4G/VPNThe power grid communication method enables remote transmission and communication of local data. Operations and maintenance personnel can configure parameters and remotely upgrade terminals through the Dunheng Power IoT platform, and can also use SMS andWebThe client can view relevant information in real time, and can timely grasp the operation status of the line no matter where it is.

35kVThe fault location device for collection line cables has become an important tool for ensuring the stable operation of power systems due to its wide range of application scenarios and outstanding advantages, providing strong support for the sustainable development of the power industry.
