The invention provides a positioning method and apparatus for a suspension point of a lead. The method comprises: transmission line data are obtained, wherein the transmission line data include power line point clouds, tower point clouds, and insulator chain point clouds; an insulator chain point cloud associated with each of one or more insulator chains belonging to a specific tower is extracted from the obtained insulator chain point clouds; For each of one or more insulator chains, a position, approaching a suspension point of the tower, of the insulator chain is determined based on the insulator chain point cloud associated with the insulator chain and a tower cloud point associated with the specific tower in the obtained tower point clouds; and a position, approaching a suspension point of a power line, of the insulator chain is determined based on the insulator chain point cloud associated with the insulator chain and a power line cloud point associated with the power line in a predetermined area around the specific tower among the obtained power line point cloud. With the method and apparatus, the practical lead suspension point position can be determined accurately.
Description
technical field [0001] The invention relates to the field of electric power technology, and more particularly relates to a method and a device for locating suspension points of wires. Background technique [0002] Transmission lines are the infrastructure of a country. Transmission line sag ("sag" for short) is one of the main indicators that need to be considered in line design and operation and maintenance. When the sag is too small, the tensile stress of the overhead line is too large, the load on the tower increases, and the safety factor decreases. Insufficient safety distances and crossovers, the risk of line blackout accidents caused by wind swings, galloping and jumping increases accordingly. Therefore, it is necessary to monitor the sag in real time during the daily inspection of the transmission line, and at the same time, it is necessary to simulate the sag under extreme weather conditions, and try to control the sag within the range required by the regulations ...
