Description

technical field [0001] The invention relates to a mechanical monitoring and analysis method for ground wires of overhead transmission lines, which belongs to the technical field of electric power industry. Background technique [0002] In recent years, the power grid system has paid more and more attention to the online monitoring of transmission lines, and made great efforts to conduct research on online monitoring of transmission lines. After applying the research results to actual lines, unexpected problems occurred: [0003] 1) The sensor power supply is wind power, photovoltaic power supply or a combination of the two. It is exposed to the natural environment and has a short life. In most cases, it will be damaged within a few months, which cannot guarantee the continuous and effective operation of the monitoring device; [0004] 2) Traditional sensors only perform qualitative detection of appearances, and cannot detect the force data of line materials (components), and...

Problems solved by technology

[0003] 1) The sensor power supply is wind power, photovoltaic power supply or a combination of the two. It is exposed to the natural environment and has a short life. In most cases, it will be damaged within a few months, which cannot guarantee the continuous and effective operation of the monitoring device;

[0004] 2) Traditional sensors only perform qualitative detection of appearances, and cannot detect the force data of line materials (components), and cannot form digital analysis, making it difficult to achieve refined management of transmission lines;

[0005] 3) The technology of the auxiliary equipment of the sensing device is immature and requires continuous operation and maintenance, which increases the labor intensity of the operation and maintenance personnel in actual work

[0009] To sum up, from a practical point of view, in terms of online detection of overhead transmission lines, cable lines, especially UHV, EHV, and ground wires of the main grid structure, there has not yet been a reasonable and effective overhead transmission line.
