500 kV 变电站导线力学计算的研究

Mechanical Calculation for Conductors in 500 kV Substations

论述了ＬＧＪＱＴ－１４００和ＫＫＺ－５８７两种导线因其截面较大，变电站设备间的距离又较短，而存在着一定的抗弯刚度，以及导线按一般悬链线计算的不合理性。通过试验建立了多元回归方程，为端子设计提供了新的计算方法。

This paper discusses the bending rigidity existing on conductors of types LGJQT1400 and KKZ587 with larger cross section area, installed in substations with shorter distance between equipment and the irrationality of conductor mechanical calculation based on suspending strings. A new multielemental regression method is setup through experiments for terminal design.
