| 摘 要： | 导(地)线断线严重影响输电线路的安全运行。针对特高压直流线路的特点,采用ABAQUS软件建立了分裂导线连续档断线模型。通过有限元分析,求得V型绝缘子串的摆幅、冲击荷载以及各相导线的断线荷载。通过与断线荷载理论计算结果比较可知:我国现有线路规程关于断线荷载的取值是合理的,按规程设计线路在一定程度上能够抑制倒塔事故的发生。

| Abstract: | The breakage of conductor/ground wire seriously affects the secure operation of transmission line. According to the features of UHVDC power transmission lines, the broken conductor model for bundled conductors of continuous span is built by finite element software ABAQUS, and through the simulation of conductor breakage happened in continuous spans the swing amplitude of V-shaped insulator strings, the impact load and the broken conductor load of phase conductors are obtained. Comparing the simulation resul... |
