Description

一种双框架阻尼型间隔棒
技术领域
本发明涉及一种双框架阻尼型间隔棒。
背景技术
远距离、大容量的超高压输电线每相导线采用二根、四根及以上的***导线。目前220KV及330KV的输电线采用二***导线，500KV输电线采用三***及四***导线，电压高于500KV的超高压输电线采用六***及更多***的导线。为了保证***导线线束间距保持不变以满足电气性能，降低表面电位梯度，及在短路情况下，导线线束间不致产生电磁力，造成相互吸引碰撞，或虽引起瞬间的吸引碰撞，但事故消除后即能恢复到正常状态，因而在档距中相隔一定距离安装了间隔棒。安装间隔棒对次档距的振荡和微风振动也可起到一定的抑制作用。
按间隔棒的工作特性大体可分为两类，即阻尼型间隔棒及非阻尼型间隔棒。阻尼型间隔棒特点是：在间隔棒活动关节处利用橡胶作阻尼材料来消耗导线的振动能量，对导线振动产生阻尼作用。
现有的阻尼型间隔棒一般在框架主体和夹头主体上各预留四个或者八个能卡住橡胶柱的安装孔，这些橡胶柱构成阻尼***，该阻尼***来消耗导线的振动能量，对导线振动产生阻尼作用。然而这种安装橡胶柱的阻尼型间隔棒存在以下缺点：一是橡胶柱安装麻烦，需要不断调整橡胶柱的位置才能保证将所有的橡胶柱安装到位，对安装工人的要求比较高；二是在高空长距离运输中需要质量比较轻的阻尼型间隔棒，然而这种结构的阻尼型间隔棒比较重，不适于高空长距离运输。

作为上述技术方案的进一步改进，所述夹头安装腔的敞口端两侧均安装有限位块，所述限位块的工作面与夹头主体的中心线间的夹角为15°。
作为上述技术方案的进一步改进，所述锁紧机构包括依次贯通框架主体、第一橡胶块、夹头主体的铰接端和第二橡胶块的螺杆，所述螺杆上安装有将框架主体、第一橡胶块、夹头主体的铰接端和第二橡胶块锁紧后使得第一橡胶块和第二橡胶块变形的螺母。

具体实施方式
下面结合附图，详细说明本发明的应用。
参照图1～图5， 一种双框架阻尼型间隔棒，其包括框架主体1，所述框架主体1上设有多个一端敞口的夹头安装腔10，相邻的夹头安装腔10之间的间隔相等，所述夹头安装腔10内均铰接有夹头主体2，所述夹头主体2的自由端安装有其一端与夹头主体2铰接的夹头压盖3，夹头主体2的铰接端的下端面与夹头安装腔10之间设有第一橡胶块30，夹头主体2的铰接端的上端面设有第二橡胶块31，所述第二橡胶块31和框架主体1之间安装有将第一橡胶块30和第二橡胶块31锁紧并变形的锁紧机构。
通过夹头主体2的铰接端的下端面与夹头安装腔之间设有第一橡胶块30，夹头主体2的铰接端的上端面设有第二橡胶块31，所述第二橡胶块31和框架主体1之间安装有将第一橡胶块30和第二橡胶块31锁紧并变形的锁紧机构，使得第一橡胶块30和第二橡胶块31安装后的变形量在15%左右，两块橡胶块组成一个阻尼机构，来消耗导线的振动能量，对导线振动产生阻尼作用，这种结构方式结构简单，安装方便。
进一步作为优选的实施方式，所述第一橡胶块30和第二橡胶块31为形状一致、大小相等的椭圆形橡胶块，所述夹头主体1的铰接端的上端面设有安放第二橡胶块31的椭圆形的第二安装槽21，夹头主体的铰接端的下端面设有安放第一橡胶块30的椭圆形的第一安装槽22，所述夹头安装腔1内设有能容纳第一橡胶块30的椭圆形的安装槽11 。第一橡胶块30和第二橡胶块31为形状一致、大小相等的椭圆形橡胶块，由于椭圆形橡胶块不是关于任意轴对称的零件，故椭圆形橡胶块不会在安装槽内转动。当导线振动，椭圆形的第一橡胶块30和第二橡胶块31会对安装槽11、第一安装槽22、第二安装槽21的内壁进行挤压，对导线振动产生阻尼作用，并通过橡胶块的变形也来消耗导线的振动能量。
进一步作为优选的实施方式，所述第一安装槽22与第二安装槽21之间设有隔板，所述隔板上设有多个通孔，安装时，第一橡胶块30和第二橡胶块31有部分橡胶会填充通孔。
进一步作为优选的实施方式，所述夹头安装腔10的敞口端两侧均安装有限位块12，所述限位块12的工作面与夹头主体2的中心线间的夹角为15°，使得夹头主体2在±15°的范围内摆动。
进一步作为优选的实施方式，所述锁紧机构包括依次贯通框架主体1、第一橡胶块30、夹头主体2的铰接端和第二橡胶块31的螺杆32，所述螺杆32上安装有将框架主体1、第一橡胶块30、夹头主体2的铰接端和第二橡胶块31锁紧后使得第一橡胶块30和第二橡胶块31变形的螺母33，锁紧结构安装方便。
进一步作为优选的实施方式，所述夹头安装腔10的数量为2个、3个、4个、6个和8个中的一种，可根据不同的输电电压选择二***式间隔棒、三***式间隔棒、四***式间隔棒、六***式间隔棒和八***式间隔棒。
以上是对本发明的较佳实施方式进行了具体说明，但本发明创造并不限于所述实施例，熟悉本领域的技术人员在不违背本发明精神的前提下还可作出种种的等同变型或替换，这些等同的变型或替换均包含在本申请权利要求所限定的范围内。
