电力钢管杆失效解析及改进对策

Analysis on Failure of Electric Poles and the Improvement

通过对一起10 kV钢管杆强度不足的全过程失效分析,从杆塔设计、杆型结构、材料选用、制造施工等多个环节着手,分析可能引起挠度超标和节点弯曲的原因,提出相应的改进对策,并取得了良好的效果。

By analysis on a whole-process plores the reasons of excessive deflection structure, material selection, manufacture vorable effect is achieved. failure of 10 kV steel poles due to poor strength, the paper ex- and node bending in terms of design of poles and towers, pole and construction; it proposes relevant improvement, in which fa-vorable effect is achieved.
