Description
technical field [0001] The invention belongs to the technical field of high-voltage stringing, and more specifically relates to a device and method for measuring the sag value of an overhead line. Background technique [0002] Sag refers to the vertical distance between any point on the suspension curve of the conductor and the line connecting the suspension points on both sides. If the sag value of the overhead line is too small, it means that the tensile force of the conductor is large, which will lead to aggravated conductor vibration and reduced service life. If the sag value is too large, it means that the tension on the conductor is small, which will reduce the distance between the conductor and the ground or across the object, and reduce the safety of power transmission. Therefore, in the construction and acceptance of overhead transmission lines, sag must be considered an important indicator of . [0003] At present, the commonly used method to detect the sag value ...
