摘　　要：500 kV超高压变电站设备损坏原因是因为导线截面较大,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。通过荷载试验,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 introduced that the reason of the equipments damage in EHV substation was because of large cross section of the conductor, as well as the short distance between equipments of the substation. It is also resulted by the bending rigidity and the unreasonable theory of the general catenoid calculation of the conductor. We have established the data regression equation, which is based on load experimene, and provided new calculation method for terminals on EHV substation design.
