Design and manufacture of 110 kV overhead transmission line and linear tower model

Abstract

This design mainly describes the design of 110kV overhead transmission line and the design and manufacture of linear tower model. Overhead transmission line is an indispensable part of the power system. Power lines are divided into transmission lines and distribution lines. With the continuous development of China's power industry, overhead transmission lines have developed in an all-round way towards higher and higher voltage level, lower comprehensive cost, higher live line operation, higher transmission power rate, etc. I choose the straight-line tower, and then we find out from the table It has required data and calculated corresponding data, such as load calculation according to the selected conductor and ground wire; stress sag calculation; lightning wire stress sag calculation; drawing the stress and sag curve of the conductor and ground wire; calculation of the unbalanced tension and angle resultant force of the wire, calculation of the installation load of the straight pole tower, calculation of the dimension of section ⑤ ⑥ ⑦ ⑧ ⑨ of the selected tower type, and finally drawing the model according to 20:1 Type drawing. In the process of making poles and towers, we first select the materials, then cut the materials, number the sections, then assemble them, and finally accept them..

Key words: ground guide; stress sag; row bar positioning; load; check
