Abstract

The invention discloses an accurate calculation method for dynamic simulation of tension stringing. Firstly, a stretch stress calculation model with the outlet tension of a tension machine as an independent variable is established, a corresponding stringing curve is automatically drawn in a cross-section diagram, and a stringing flow chart is drawn through combination of the stringing curve and graphics of the cross-section diagram and superposition of starting coordinates of stringing sections and corresponding coordinates in the cross-section diagram; the stringing flow chart is used for successively adjusting the position of a walking board to the nth based tackle one by one from the side of a tension field, and the above process is executed again; the dynamic simulation of the stretchstress and the axial tension of the entire stringing section is achieved; after the stretch stress and the axial tension of all the stringing sections meet the requirements of stringing, the outlet tension of a single sub-conductor of the tension machine is the independent variable, and a stringing force matrix table is made to accurately reflect the force status of each part and facilitate guiding of on-site construction.

Description

technical field [0001] The invention relates to the technical field of tension stringing construction of power transmission and distribution lines, in particular to a magnetic-drive photoelectric liquid level gauge for boiler water level monitoring. Background technique [0002] In the tension stringing construction of transmission lines, it is necessary to calculate the pay-off control gear and the pay-off tension. The conventional calculation method is to select the control gear (that is, the control point) based on experience, and determine the control gear according to the height and position relationship of the control gear. The horizontal tension of the file. The selection of control points is very important, especially when the control object is the ground and the ground is undulating. Due to the influence of terrain undulations and friction coefficients, multiple control gears are required for comparison. The selection of control points is not accurate enough, and th...
