Abstract

The invention discloses a power transmission line construction stringing early warning method, which comprises the steps of collecting a first real-time tension and a second real-time tension at two ends of a power transmission line, and solving a real-time resultant force; solving the real-time line point axle distance of the real-time point position of the wireless remote control trolley; solving a standard line point axle distance; obtaining a standard sag of the power transmission line; according to the real-time line point shaft distance and the standard sag, judging whether power transmission tower line stringing is qualified or not; and when the maximum value of the real-time line point axle distance is not within the preset range of the sag, determining that the power transmissionline tightening is unqualified, sending an alarm signal by an alarm, and loosening and tightening the power transmission line according to the alarm signal. 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 effectivelyreduced.

Description

technical field [0001] The invention relates to the technical field of transmission line construction, in particular to an early warning method for transmission line construction tightness. 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 many hazards to t...
