Power transmission line icing monitoring and early warning method and system

Abstract

The invention relates to a power transmission line icing monitoring and early warning method and system. The power transmission line icing monitoring and early warning method comprises the following steps: acquiring the weight of each cable in real time, and generating tension value data; obtaining tension value data at intervals, and inputting the tension value data into a tension judgment model preset with a tension reference value to generate a judgment result; and when the judgment result is that the tension value data continuously exceeds the tension reference value, sending an early warning signal to an operation and maintenance user side, wherein the operation and maintenance user side is bound with an operation and maintenance worker responsible for the cable. According to the invention, the device has the advantages that early warning can be given to workers in time when the power transmission line is iced, the workers can clean the iced power transmission line in time, and damage to the power transmission line is not likely to be caused.

Description

technical field [0001] The present application relates to the technical field of power transmission cables, in particular to a method and system for monitoring and early warning of icing on power transmission lines. Background technique [0002] Rime is formed when cold raindrops fall on objects with temperatures below freezing. If the condensation is on the power transmission cable, it will cause the cable to be iced. [0003] The two ends of the cable are fixed between two adjacent towers through insulator strings. The mechanical load increases with the increase of ice coating, and the weight of ice on the cables, insulator strings and towers increases. If The staff failed to monitor the icing situation of the cables and clean up the cables in time when the icing was serious. When the load exceeds the allowable value of the strength of the above-mentioned components, it is easy to cause the cable to break or the tower to collapse, resulting in damage to the transmission l...
