摘要
针对辽宁省内几起输电线路杆塔导线断线情况,重点分析了使用双独立挂点的悬垂线夹结构的受力情况,通过计算导线和金具在扭动状态下的动弯应力进行金属疲劳分析,找到目前线夹结构的不足,为线路安全稳定运行提供参考经验。
Through analysing the force structure, it uses double hanging point independent suspension clamp in the case of severaltransmission tower line break accident in Liaoning. By wire and fittings in the twisted state dynamic bending stress calculation of metalfatigue analysis, it finds out the deficiency of suspension clamp to provide reference for the safe and stable operation line.
