摘　　要：文章计算分析了云南覆冰、大风等极端工况环境下水泥杆的载荷,基于云南配网10 kV线路水泥杆类型、导线、土壤等参数建立了直线杆、转角杆、小转角杆的有限元力学分析模型,研究了极端工况下的水泥杆最小埋深需求,并提出了改进措施。结果表明:12 m直线杆最小埋深为1.80 m,国标规定的最小埋深足够;转角杆(转角15°)、小转角杆(转角5°)国标规定最小埋深不足,可在水泥杆底部浇筑钢筋混凝土底盘以增加水泥杆抗倾覆能力;不均匀覆冰工况(覆冰厚度30 mm)直线杆、转角杆、小转角杆国标规定最小埋深均不足,将出现倒杆,须及时除冰。研究成果对国标规定最小埋深进行了有效补充。To solve this proble m,the load of ce ment pole under extre me working conditions such as ice covering and wind in Yunnan was calculated and analyzed.Based on the para meters of ce ment pole type,wire and soil of 10 kV line in Yunnan distribution network,the finite ele ment mechanical analysis model of linear pole,Angle pole and s mall Angle pole was established.The mini mu m buried depth require ment of ce ment pole under extre me working conditions was studied,and i mprove ment measures were proposed.The results show that the mini mu m buried depth of the linear rod is 1.80 m,which is sufficient according to the national standard.Angle pole(Angle 15°),s mall Angle pole(Angle 5°) the mini mu m depth specified in the national standard is insufficient,and reinforced concrete chassis can be poured at the botto m of the ce ment pole to increase the anti-overturning ability of the ce ment pole;Uneven ice cover conditions(ice cover thickness 30 mm) linear rod,Angle rod,s mall Angle rod mini mu m buried depth stipulated by the national standard are insufficient,there will be a reverse rod,need to be deiced in ti me.The research results are an effective supple ment to the mini mu m burial depth stipulated by the national standard.
