Abstract:Ansoft simulation software was used to carry out three-dimensional simulation to the different barrier below 500 kV extra-high voltage power transmission line. This paper analyzed its impacts on unmanned aerial vehicle line patrol based on electromagnetic field distance measurement. This paper expound the electric field distribution situation above and below the diagonal of overhead lines, giving house model, hillside model, water surface model, crossing potamic electric transmission line model and its simulation results in consideration of sag conditions, which provides references for maintainers to carry out unmanned aerial vehicle line patrol based on electric field distance measurement.
Key words:electric transmission line; electric field distribution; simulated analysis
