Abstract

本发明属于一种电力金具，确切的说是属于一种多功能耐张线夹。本发明特点是耐张线夹管体有螺旋环绕条纹，以扰动气流并阻止形成规则的覆冰，来降低和减少输电线路舞动。本发明结构简单，适用范围广泛，可应用于传统钢芯铝绞线、耐热铝合金导线、碳纤维复合芯导线、间隙型导线。本发明施工方便，适合各种电压等级的输变电线路。

Description

多功能耐张线夹
技术领域
本发明属于一种电力金具，确切的说是一种多功能耐张线夹。
背景技术
现有的架空输电导线使用的耐张线夹只有连接牵引导线的作用，容易受风力而摆动，还容易受湿冷天气结成覆冰，进而造成输电线路舞动。
发明内容
本发明目的在于提供一种多功能耐张线夹，其特征是通过改变原有耐张线夹外形，以减小风阻；改变耐张线夹覆冰轮廓，改变耐张线夹覆冰时空气动力外形，进而减少输电线路舞动几率并降低输电线路舞动幅度。
本发明目的由以下方法实现：
在耐张线夹管体外侧有环绕的螺旋条纹，螺旋形状改变该耐张线夹部位的空气动力形状，可以使耐张线夹沿长度方向上的受风横截面不断变化；还可以在湿冷天气下使耐张线夹外覆冰轮廓为不规则形状，使截面沿螺旋方向变化，以致风力所产生的空气动力效应相互干扰与制约，从而破坏了起舞的条件：使其升力系数减小，升力系数曲线变化趋于平稳，其阻力系数的增大能使导线在运动过程中消耗更多的能量，有利于减少输电线路舞动几率并降低输电线路舞动幅度。
由于采用了上述方案，使得本发明在使用中，可减小风阻，并减少输电线路舞动几率并降低输电线路舞动幅度。
下面结合附图对本发明做详细说明：
附图说明
附图为本发明的纵向剖面图：在耐张线夹管体1的外侧有环绕的螺旋条纹2。
具体实施方式
在耐张线夹管体1的外侧有环绕的螺旋条纹2，螺旋条纹2的螺旋形状改变该耐张线夹部位的空气动力形状，可以使耐张线夹沿长度方向上的受风横截面不断变化；还可以在湿冷天气下使耐张线夹外覆冰轮廓为不规则形状，使截面沿螺旋方向变化，以致风力所产生的空气动力效应相互干扰与制约，从而破坏了起舞的条件：使其升力系数减小，升力系数曲线变化趋于平稳，其阻力系数的增大能使导线在运动过程中消耗更多的能量，有利于减少输电线路舞动几率并降低输电线路舞动幅度。
