A method and device for measuring the space electric field of an insulator of a transmission line

Abstract

The invention discloses a method and device for measuring the spatial electric field of an insulator of a power transmission line. The method comprises: establishing a plurality of target paths of an unmanned aerial vehicle from a starting point coordinate to an end point coordinate, and storing the position coordinates of each target path; setting the unmanned aerial vehicle to automatically cruise along the plurality of target paths, and obtaining the electric field data of each target path; generating a corresponding path electric field distribution curve according to the position coordinates and electric field data of each target path; generating a spatial electric field distribution curve according to the electric field distribution curves of all paths; the invention can fuse the information of the measured electric field intensity with the corresponding spatial coordinates, accurately obtain the spatial electric field intensity on the target path, make up for the measurement result errors caused by the attitude disturbance of the unmanned aerial vehicle and the path deviation in the previous non-contact measurement method, and realize the non-contact high-precision live measurement of the spatial electric field of the insulator string of the overhead line.
