Installation Projects：Transmission line non-contact fault diagnostic device Installation cases
Project time：2024.04.02
Project completion unit：Shenzhen Dinsee Smart Technology Co.,LTD.
The traditional traveling wave ranging in high-voltage transmission is not ideal, and it is difficult to meet the requirements of fault finding. The non-contact fault diagnostic device for transmission lines adopts a new fault location method for transmission lines, combining distributed installation, non-contact traveling wave acquisition and distributed ranging algorithms. On the one hand, to solve the problem of signal attenuation in long-distance beast transmission lines and high impedance fault traveling wave monitoring, significantly improve the reliability of fault ranging, to ensure that the ranging accuracy of high resistance grounding and other complex situations; on the other hand, it can be a transient fault statistical analysis, early warning, to prevent the occurrence of tripping faults; it can be a statistical analysis of lightning strikes in the section, to provide data for reference for lightning protection and effects. In the long term, it can also achieve the white I identification of tripping faults. The use of non-contact signal acquisition, no contact with the high-voltage part, which is convenient for the installation and maintenance of the system.
The new system is proposed to provide effective technical support for rapid fault location, fault cause analysis and power supply restoration of long-distance transmission lines and intelligent substation transmission lines, and realize accurate fault location. And the fault results will be sent to the set cell phone, you can also view the distance measurement results through the Web, client or cell phone, to provide rich fault data support for the operation and inspection personnel, can timely and accurately inform the fault section and the distance of the fault, so as to facilitate the personnel to carry out maintenance, so that the power system to resume normal operation as soon as possible, to reduce the loss of the power system, which is important for enhancing the reliability of the power supply, to improve the quality of the power supply, and to improve the efficiency of the operation and maintenance. This is of great significance for enhancing power supply reliability, improving power quality and improving operation and maintenance efficiency.
