In the 21st century, the field of distribution lines has undergone profound and all-encompassing changes and developments. In terms of scale, according to the statistics of 2022, the total length of distribution lines of power grid companies has reached about 3.6 million kilometers, and the length of medium-voltage distribution lines has grown to more than 4 million kilometers from the previous base in the period of 2015 to 2020, and the coverage of lines is like a huge and fine grid, extending to all corners of the city and vast countryside, which provides constant power support to the economic development and the life of the residents. providing constant power support for economic development and residents' lives.
With the advancement of new energy, distribution lines have also made significant breakthroughs in new energy access and carrying capacity. In the face of the massive emergence of distributed new energy sources such as solar and wind power generators, distribution grids are actively adapting to change. According to the plan, by 2025 the distribution grid should have about 500 million kilowatts of distributed new energy access capacity and about 12 million charging pile access capacity.
In this wave of development, Shenzhen Dingxin Wisdom Technology Distribution network traveling wave fault early warning and positioning device stands out as a core tool for intelligent operation and maintenance of distribution lines. It is a compact design, easy to install in the distribution line conductor side of the different phases, does not occupy too much space and support the installation of convenient power. Its conductor direct measurement function is a major highlight, directly from the conductor to obtain traveling wave data, "first-hand information" to avoid the interference and attenuation of the signal transmission process.
The key is that the distribution network traveling wave fault warning and positioning device can realize instant monitoring and warning. Through the real-time monitoring of the conductor traveling wave, once the fault occurs, it can instantly capture the changes in the traveling wave signal and quickly start the fault ranging calculation. With advanced algorithms and sophisticated technology, the fault ranging calculation accuracy can be controlled within 150 meters, which is of great value in the huge and complex distribution line network.
At the same time, it can also provide real-time diagnostic information such as fault time, fault distance, and corresponding tower number, so that the operation and maintenance personnel can quickly obtain the details of the fault. For example, when a distribution line failure, operation and maintenance personnel can immediately receive the device in the monitoring center to send information including the failure occurred at [specific time], the fault point from [starting point] [distance], located in [specific tower number] and so on detailed information. This makes the operation and maintenance personnel can quickly develop repair programs, straight to the scene does not fall through!
