Abstract

The invention discloses a stringing construction method for an overhead transmission line. The stringing construction method comprises the following steps: respectively lifting a first high-altitude traction machine and a second high-altitude traction machine; lifting a strain insulator string by using a lifting steel wire rope; starting a tensioning high-altitude traction machine to tension a power transmission line; solving the standard gravity of the power transmission line; solving real-time resultant force; solving the real-time line point axle distance of the real-time point position ofa wireless remote control trolley; solving a standard line point axle distance; obtaining the maximum value of the standard line point axle distance, and obtaining the standard sag of the power transmission line; and judging whether the power transmission tower line tightening is qualified or not according to the real-time line point shaft distance and the standard sag. According to the invention,whether the power transmission tower line tightening is qualified or not is judged through the real-time line point shaft distance and the standard sag, so that the power transmission tower line is tightened and loosened accurately, the sag of the power transmission tower line is effectively controlled within a preset range, and the harm of the power transmission tower line in subsequent operation is effectively reduced.

Description

technical field [0001] The invention relates to the technical field of wire erection of transmission towers, in particular to a construction method for tightening wires of overhead power transmission lines. Background technique [0002] Overhead transmission lines are the main artery of the power industry and an important part of the power system. The transmission line conductor sags between adjacent towers to form an arc curve, and the sag is called sag. The size of the sag is related to the span, height difference, wire length, wire weight, and stress on the wire. Natural factors such as temperature, wind, ice and snow also affect it. It is an important process to ensure the construction quality to accurately observe the sag of the overhead transmission line and guide the line tightening operation until the target sag is achieved. [0003] After the line tightening operation is completed, if the sag of the conductor deviates too much from the target value, it will bring ...
