摘要
分析了导体和接地线在断裂和撞击电压为 330 千伏的架空输电线杆塔时的拉力变化。根据分析结果，建立了一个由钢塔、导体、接地线和绝缘元件组成的统一斜拉索系统的数学模型。该模型的方程组使用 MS Excel 电子表格处理器对各种断裂情况进行迭代求解。文中给出了导线和接地线断裂时拉伸力的相关性，以及线性回路中塔杆的作用力，并考虑了相邻塔杆的支撑作用。
Interaction of Structural Elements in the Overhead Transmission Power Line
The analysis of the changes of tensile forces in conductors and earth wires is performed during their breakage and impact on the towers of overhead power line with a voltage of 330 kV. Based on the results, a mathematical model of a unified cable-stayed rod system consisting of steel towers, conductors and earth wires and insulating elements has been compiled. The system of equations of the model is solved iteratively using the MS Excel spreadsheet processor for various breakage cases. The dependences of tensile forces in conductors and earth wires during their breakage are presented, as well as the forces which correspond to an acting regime on towers in a linear circuit, taking into account the supporting effect of neighboring towers.
