摘要
Abstract
When the transmission line tower is affected by abnormal external force,the settlement and slip will cause the tension change under the condition of equal line length.This article establishes a tension model under the condition of fixed payline length through a calculation model of transmission line route length,and uses changes in span and height difference to simulate settlement and sliding phenomena caused by changes in external environmental parameters,calculate the tension change value after external environmental parameters change under equal line length conditions,and at the same time,calculate the tension change trend of wires with different parameters under external environmental changes.Summarize the measures that can be taken to reduce tension values and improve the reliability of transmission lines under external environmental changes.关键词
