The embodiment of the invention discloses a method for calculating a tree felling range below a power transmission line, and the method is characterized in that the method comprises the steps: 100, obtaining a sag parameter of a wire between two towers of the power transmission line; 200, according to the wire sag parameters, calculating the width values between the conductor and the forest area in the static state, the maximum windage yaw state and the middle deflection angle state; and step 300, taking the maximum width value and margin value of the wire in the three states as a final felling range. According to the method, the offline tree felling range is calculated through the conductor sag between the two towers of the line, specifically, the distance between the forest area and thewire under the static state, the maximum distance state and the middle deflection angle state of the conductor is calculated according to the determined conductor parameters, and the width of the treefelling range is obtained according to the calculation result; according to the calculated tree felling range scheme, line engineering characteristics are fully considered, various key parameter results concerned by tree felling range design can be provided, comparison by designers is facilitated, and the method is simple and easy to implement.
Description
technical field [0001] Embodiments of the present invention relate to the technical field of tree felling on power transmission lines, and in particular to a method for calculating the felling range of trees under power transmission lines. Background technique [0002] With the rapid development of my country's urbanization and industrial modernization, the scale of transmission line projects continues to expand, making the construction of urban power grids to spend considerable energy and money on the cleaning of line corridors. In the current transmission line design project, the efficiency and accuracy of ground survey are low, the accuracy is not high, the line is easy to change in the later stage, and the compensation is difficult, which brings great challenges to the design work. [0003] Due to technical and policy reasons, it is necessary to cut down trees, and the cutting width shall be determined according to the following conditions: [0004] ①Trees height shall ...
