A method and a device for monitoring the safe discharge distance of a high-voltage line to a tree

Abstract

The invention provides a method and a device for monitoring the safe discharge distance of a high-voltage line to a tree, wherein the method comprises the following steps: S100, determining a coordinate base point according to the positions of each camera head and each high-voltage line; S200, according to the coordinate base point, taking the direction perpendicular to the high voltage line and parallel to the ground as the x-axis, the direction along the high voltage line as the y-axis, and the vertical direction from the high voltage line to the ground as the z-axis to establish a three-dimensional coordinate system; S300, sequentially generating a computing tangent plane perpendicular to the y-axis along the y-axis direction according to a preset pitch; S400, obtaining the intersectionpoint coordinates of each high voltage line and the calculation tangent plane, and obtaining the dangerous point coordinates of each branch and the calculation tangent plane; S500, calculating a plane distance between the coordinates of each dangerous point and the coordinates of each intersection point; S600, judging whether each of the plane distances is safe, and repeatedly executing steps S300-S600. The monitoring method provided by the present application can effectively solve the problem of low accuracy of a conventional monitoring method.

Description

technical field [0001] The present application relates to the field of power system equipment maintenance, in particular to a method and device for monitoring the safe distance between high-voltage line-to-tree discharges. Background technique [0002] Forest fire is the most dangerous enemy of forests and the most terrible disaster in forestry, especially in areas covered by power grids, which are especially prone to forest fires. Due to the blowing effect of the wind on the transmission line, the transmission line will continue to rub against the adjacent branches, which will damage the insulating skin on the surface and expose the internal metal wires. When it rains, the exposed metal wires will pass through the wet branches. The current is led to the ground, causing a non-metallic short circuit, resulting in a large short circuit current, and a forest fire occurs. Forest fires will not only cause devastating damage to forest resources, but also seriously endanger the sa...
