The traditional traveling wave ranging in high-voltage transmission is not ideal, and it is difficult to meet the requirements of finding the fault point. The transmission line non-contact fault diagnostic device adopts a new method of fault location on transmission lines, with a combination of distributed installation, non-contact traveling wave acquisition and distributed ranging algorithm. On the one hand, to solve the problem of signal attenuation in long-distance 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 statistical analysis of transient faults, early warning, to prevent the occurrence of tripping faults; it can be a statistical analysis of lightning strikes on the section, to provide data for reference for lightning protection and effects. In the long run, it can also achieve self-recognition 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 rapid restoration of power supply for long-distance transmission lines and intelligent substation transmission lines, and to realize accurate fault location. And the fault results will be sent to the set cell phone, can also be viewed through the Web, client or cell phone ranging results, for the operation and inspection personnel to provide a wealth of fault data support, can timely and accurately inform the fault section and fault distance, to facilitate the personnel to carry out overhaul, so that the power system as soon as possible to restore normal operation, to reduce the loss of the power supply reliability, improve the quality of power supply, and improve the efficiency of operation and maintenance, which has an important significance. This is of great significance to enhance power supply reliability, improve power quality, and improve operation and maintenance efficiency.
Since its inception, our company has been committed to the study of smart grid, is a technology development, production, sales and technical services in one of the solution providers, has for China's different voltage levels of power equipment to provide a full range of systematic solutions and products, so that the smart grid within reach.
