摘　　要：由于我国新建输电线路多采用铝钢比大的大截面导线和分裂导线形式,因而易引起导线在展放过程中起灯笼和舞动。文章分析了架空导线产生扭转的原因以及导线舞动与扭转刚度之间的关系,在对工程需要及国外情况进行调研的基础上提出了扭力矩试验方法,并对扭力矩试验的专用设备的研制进行了探讨和实践,还提出了扭力矩试验参数应用于分裂导线扭转失稳控制的具体方法。Since large section and split conductor with big ratio of aluminum and steel is adopted in new power transmission lines in China, the conductor wave is easy to produce. The paper analyzed the reason of twisting for overhead conductor and the relations between conductor wave and rigidity, put forward the test method of twisting moment based on the needs of project and investigation of foreign condition, and discussed the P.＆D of the special equipment for twisting moment test, still put forward the specific method for twisting moment test parameters applied in twisting instability control of split conductor.
