In the field of power transmission,35kVThe stable operation of collection line cables is crucial, and cable fault location devices are the key to ensuring their normal operation“guard”Below, we will delve deeper into the analysis35kVThe structure and characteristics of the fault location device for power collection line cables.

Exquisite and reasonable structure

35kVThe fault location device for collection line cables mainly consists of three parts: distribution network diagnostic device, monitoring platform, and communication module. The distribution network diagnostic device is part of the entire system“Front end sensor”It is cleverly installed on the main and branch lines of the distribution network. Among them, the main line positioning device and the section positioning device have clear division of labor and work together, which can quickly capture the fault traveling wave signal and fault power frequency signal of the distribution network. The monitoring platform serves as“Smart Brain”Receive data uploaded from the distribution network diagnostic device, use advanced artificial intelligence deep learning algorithms to deeply analyze the data, accurately diagnose fault types, and output results. The communication module is similar to“Information Bridge”, using4G/VPNThe power grid communication method enables real-time data transmission between the distribution network diagnostic device and the monitoring platform, ensuring smooth information flow.

Distinctive advantages

Accurate positioning with minimal error

This device achieves high-precision fault location by installing positioning devices at different positions in the distribution network. Its positioning accuracy is less than100Mi, this feature enables operation and maintenance personnel to quickly and accurately locate the fault point, greatly reducing the troubleshooting time, improving the efficiency of fault repair, and effectively reducing the scope and duration of power outages.

Intelligent recognition, efficient and fast

The use of artificial intelligence deep learning algorithms for fault recognition 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 intelligent recognition capability enables operation and maintenance personnel to quickly understand the nature of faults and develop scientific and reasonable maintenance plans.

Multi functional and comprehensive monitoring

In addition to precise positioning and intelligent fault recognition, the device also has rich monitoring functions. It can accurately record real-time fault current and traveling wave current, providing detailed and reliable data for fault analysis; At the same time, real-time monitoring of power quality parameters such as current, frequency, and harmonics at the installation point, and rapid alerting for situations exceeding the threshold range; It can also focus on monitoring overloaded and overloaded lines to detect potential hazards in advance. In addition, it can also monitor environmental parameters such as overhead wire temperature, sag, and dancing in real time.

Remote control, convenient and flexible

With the help of the communication module, operation and maintenance personnel can remotely configure parameters and upgrade software for distribution network monitoring terminals through the Dunheng Power IoT platform. They 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, realizing convenient and flexible management of the device.

35kVThe fault location device for collection line cables provides a solid guarantee for the stable operation of the power system with its exquisite structure and excellent characteristics.
