摘　　要：预装式变电站(E-house)作为电网重要的电能传输枢纽,已经被广泛应用。在安装施工过程中,箱体质量、吊具结构、吊装速度等因素均会引起箱体形变的发生,导致设备的损坏。为了解决该问题,对所设计的9.8 m×3.2 m尺寸的E-house箱体及吊具结构进行吊装受力分析,并利用有限元方法分析了吊装结构和箱体的应力变形,确定了吊具和箱体易变形损坏部位。计算结果表明,为减少轴向压力对吊具的影响,钢丝绳安全夹角应控制在60°以内,安全的吊装速度应控制在1 m/s以下。研究结果可以为后续的箱体结构设计与优化提供理论参考。Pre-installed substation(E-house)is an important power transmission hub,which has been widely used.In the process of installation and construction,the quality of the box,the structure of the spreaders,the lifting speed and other factors will cause deformation of the box,resulting in the loss of equipment.Based on this problem,this paper analyzes the lifting force of the designed 9.8 m×3.2 m E-house box and spreader structure,and uses the finite element method to analyze the stress deformation of the lifting structure and box,and determines the easily deformable and damaged parts of the spreader and box.The calculation results show that the safety angle of wire rope should be controlled within 60°to reduce the influence of axial pressure on spindles.Safe lifting speed is controlled below 1 m/s.The research results can provide theoretical reference for the subsequent box structure design and optimization.
