摘要
自锦屏-苏南±800 kV直流输电工程起,900 mm2及以上大截面导线开始应用于我国特高压直流输电线路工程。自灵州-绍兴±800 kV直流输电工程起,1 250 mm2大截面导线开始广泛应用。为掌握微风振动条件下大截面导线的阻尼特性,基于微风振动模拟试验,以1 250 mm2系列大截面导线为对象,进行5种1 250 mm2系列大截面导线的自阻尼特性试验及分析,得出5种导线自阻尼特性的解析表达式、功率特性及频响特性,给出了1 250 mm2型线与圆线、1 250 mm2导线与1 000 mm2导线自阻尼特性的对比分析。
Since Jinping-Sunan ±800 kV DC power transmission project had been completed, application of 900 mm2 and above large-section conductors started in UHV DC transmission line in our country. And since Lingzhou-Shaoxing ±800kV UHV DC project had been completed, 1 250 mm2large-section conductors were widely used. In order to master the damping characteristics of large-section conductors in Aeolian vibration condition, self-damping characteristics of a series of1 250 mm2large-section conductors are tested and analyzed by Aeolian vibration simulation test. The self-damping analytical expressions, power characteristics and frequency response characteristics of five kinds of 1 250 mm2 conductors are obtained. And the self-damping characteristics of 1 250 mm2 shaped wire, 1 250 mm2 round wire, 1 250 mm2 conductor and1 000 mm2 conductor are analyzed and compared.
