Description

Technical Field

[0001] The utility model relates to the technical field of traveling wave ranging fault monitoring devices, in particular to a distribution network traveling wave ranging fault monitoring device. Background Art

[0002] The distribution network traveling wave ranging fault monitoring device is an advanced power monitoring device that uses the traveling wave principle to quickly and accurately locate faults in the distribution network. This device captures the traveling wave signal generated by the fault in the power line and uses a high-precision algorithm to analyze the propagation time and characteristics of the traveling wave, thereby quickly determining the location of the fault point. This technology greatly improves the efficiency and accuracy of distribution network fault troubleshooting and provides strong technical support for the stable operation of the power system.

[0003] The distribution network traveling wave ranging fault monitoring device plays a vital role in modern power systems. It can not only monitor the operating status of power lines in real time, but also quickly locate and alarm when a fault occurs, greatly shortening the fault recovery time. In addition, the device also has data storage and analysis functions, which can help power workers better understand the operation of the power grid and provide a strong basis for subsequent fault prevention and maintenance work. Through the application of this device, the reliability and safety of the power system have been significantly improved.

[0004] The traveling wave ranging fault monitoring device consists of three professional devices, and its notable feature is that it is directly installed on the conductor. This direct installation method simplifies the wiring process, reduces potential fault points, and ensures the stability and accuracy of signal transmission. This design not only demonstrates the efficiency and professionalism of the device, but also provides important technical support for fault location and troubleshooting of power systems.

[0005] However, there are some disadvantages in the installation process of the existing traveling wave ranging fault detection and monitoring device. First, during installation, the leads at both ends of the device need to be finely connected to the wires, and the insulation skin must be carefully wrapped around the connection to ensure safety. Subsequently, the device is firmly tied to the wire using special tape. However, if the device is not adequately pre-fixed before installation, the device may slip off the wire due to gravity, posing a risk of falling and damage. In addition, when disassembly and maintenance are required, the steps to remove the special tape are particularly cumbersome, as this requires careful operation to avoid damaging the device or wires. At the same time, the stickiness of the tape may also make the disassembly process time-consuming and difficult. These factors increase the complexity and risk of the installation and disassembly process. Utility Model Content
