【摘要】 本文介绍了某类型输电杆塔地线挂点,由于地线挂孔位置相对于节点中心存在偏心,易产生附加偏心弯矩,导致地线挂点处部分杆件在附加弯矩作用下发生破坏,地线支架受损。为了研究这种地线挂点的破坏机理,从理论和构造两个方面对这种地线挂点进行了深入分析,提出了相应的解决方法及建议,可供输电工程技术人员参考。更多还原

【Abstract】 A kind of transmission tower’s earth wire hanging point under the force of the big additive bending moment was analyzed,which had resulted the member near the wire hanging point losing the bearing capacity because of the additional bending moment or torsion,then the wire bracket had damaged.In order to study the damage mechanism of the earth wire hanging point,a thorough analysis was made from theory and structure.the solution and suggestions were proposed for transmission engineer.更多还原
