Description

一种阻尼调整型防次档距振荡间隔棒 技术领域
本发明涉及一种电力器材金具技术，具体讲本发明涉及一种阻尼调整型防次档距振荡间隔棒。
背景技术
近年来，随着用电需求的持续高速增长，电力发展速度进一步加快，作为关系国计民生的基础产业的电力工业迅猛发展。而优化能源资源配置，保障国家能源安全，为国民经济和社会发展提供优质、可靠的电力供应，是电力工业服务于构建社会主义和谐社会的重要使命。
超高压输电线路分裂导线上两间隔棒之间的子导线振荡的次档距振动，是采用分裂导线线路所特有的机械运动现象。就振动频率和振幅而言，振动频率约为1～3Hz，振幅为0.1～0.5m，振动轨迹呈水平扁长椭圆状的次档距振动介于微风振动与舞动之间。
微风引起导线振动及强风能诱发次档距振荡，既会直接导致导线疲劳而破坏，也可能使紧固件松动使导线磨损。阻尼间隔棒就是利用橡胶元件或者弹簧元件的弹性来获得所需要的刚度，以便能在保持分裂导线几何尺寸的同时，使其有充分的活动性。利用橡胶或弹簧的弹性在交变应力之下，吸收足够的能量以达到抑制微风振动的目的。
作为一种常用的电力器材的阻尼间隔棒，在输电线路上应用广泛，现有的间隔棒稳定性能差、强度较差、且防止次档距振荡的能力也弱，已远不能满足电力行业特高压远距离、大跨越输送发展的需要。
随着电网的不断发展，输电线路分布也越来越广，因此急需针对次档距振荡的相关措施。
本发明提供的技术方案在现有的输电线路工程次档距振荡防治措施基础上，提供了一种阻尼调整型防次档距振荡间隔棒，本发明提供的技术方案结构简单、效果明显且稳定可靠。

本发明提供一种阻尼调整型防次档距振荡间隔棒，包括：线夹、框架及弹性柱；其特征在于所述弹性柱、十字轴、线夹、线夹支架和阻尼架依次连接。
所述线夹支架一端设置与阻尼架连接的安装孔。
所述框架包括框架构件和所述十字轴。
所述线夹固定在所述十字轴。
所述阻尼架为线形或为与框架对应的多边形，框架构件的长度比阻尼架的边长长。
所述阻尼架由首尾相连的阻尼装置组成。
所述阻尼装置包括：阻尼装置安装架、阻尼盖、运动件、阻尼橡胶和I型杆，所述阻尼装置安装架包括阻尼装置安装架短端、阻尼装置安装架长端，所述阻尼盖包括上盖、下盖；所述阻尼装置安装架短端、I型杆、阻尼橡胶、运动件、阻尼盖、阻尼装置安装架长端依此连接。
所述框架边数和线夹个数相等。
所述线夹由线夹主体和线夹压盖、线夹铰链销组成，线夹主体和线夹压盖通过线夹铰链销固定。
所述线夹的十字轴四周固定有橡胶柱。
所述线夹的夹头转动安装有可360°转动的回转线夹。
所述框架上有多个通孔。
本发明通过提高间隔棒的阻尼特性，将阻尼装置安装在不同位置的安装孔内，来实现对不同次档距振荡能量的吸收，从而抑制次档距振荡的发生。阻尼调整型防次档距振荡间隔棒如图2所示。
与最接近的现有技术比，本发明的优异有益效果为：阻尼调整型防次档距振荡间隔棒在防振性能较好的多分裂阻尼间隔棒的基础上，设计增加了吸能性能更好的阻尼装置，减小导线振荡的能量和增加间隔棒吸收的能量，从而把次档距振荡抑制在安全限度内。框架上有多个通孔能起到减少材料节约成本的作用。线夹内转动安装有可360°转动的回转线夹,起到安装方便的作用，回转线夹夹线部分为橡胶材质,橡胶硬度范围在邵氏68～70度保护电线不被破坏。
