Method and equipment for measuring wire sag by using tensiometer

Abstract

The invention discloses a method and device adopting a tension meter for performing wire sag measurement, and belongs to the technical field of wire sag measurement. The method adopting the tension meter for performing wire sag measurement comprises the steps that a wire mount point tension value is measured, and real-time wire sag is obtained through calculation on the basis of a wire tension value and wire sag mathematical model. The method can obtain a corresponding wire real-time sag value by measuring a wire tension value, the wire is adjusted to the needed sag value according to the real-time wire sag value in the wire tensioning operation, the requirement for wire installation is met, no limit of special weather effects is caused when the method is adopted for measuring the tension value of the wire, and the method is applicable to wire sag measurement under various working conditions.

Description

technical field [0001] The invention relates to the technical field of wire sag measurement, in particular to a method and equipment for wire sag measurement using a tensiometer. Background technique [0002] Wire tightening construction in overhead transmission lines is a key process, which is related to the construction progress, project quality and operation safety of the project. The construction personnel carry out the line tightening operation by observing the sag of the conductor; in the actual work of the existing technology, the construction personnel need to Use theodolite or total station to observe the size of the wire sag, and adjust while observing to ensure that the sag of all wires is consistent, and finally complete the tight wire construction. [0003] At present, the more commonly used sag observation methods include parallelogram method, end-of-gear angle method, outside-gear angle method, and side-gear angle method. There is a certain deviation between ...

Problems solved by technology

[0003] At present, the more commonly used sag observation methods include parallelogram method, end-of-gear angle method, outside-gear angle method, and side-gear angle method. There is a certain deviation between the actual tension of the wire and the design theoretical tension due to the error and the personnel estimation error caused by the wire jump observation.

[0004] In addition, the slackness observation has high requirements on the environment. In case of emergency construction under special weather (smog, strong wind, night), the slackness observation cannot be carried out normally, which cannot meet the current construction needs.
