Abstract

本实用新型属于一种电力金具，确切的说是属于一种多功能接续管。本实用新型特点是接续管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。本实用新型结构简单，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。本实用新型施工方便，适合各种电压等级的输变电线路。

Description

多功能接续管
技术领域
本实用新型属于一种电力金具，确切的说是一种多功能接续管。
背景技术
现有的架空输电导线使用的接续管只有连接导线导通电流的作用，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
本实用新型目的在于提供一种多功能接续管，其特征是通过改变原有接续管外形，以减小风阻；改变接续管覆冰轮廓，改变接续管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。
本实用新型目的由以下方法实现：
在接续管管体外侧有环绕的螺旋条纹，螺旋形状改变该接续管部位的空气动力形状，可以使接续管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接续管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，使得本实用新型在使用中，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。
下面结合附图对本实用新型做详细说明：
附图说明
附图为本实用新型的纵向剖面图：在接续管管体1的外侧有环绕的螺旋条纹2。
具体实施方式
在接续管管体1的外侧有环绕的螺旋条纹2，螺旋条纹2的螺旋形状改变该接续管部位的空气动力形状，可以使接续管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接续管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。
