A preformed anti vibration hammer, which comprises a hammer body, which is characterized in that the hammer body two symmetrical connecting clamp through a steel wire, a hook shaped upper clamp, the clamp and the upper wire contact portion disposed anticorrosive rubber pad, and set the preformed. The utility model has the advantages of preformed anti vibration hammer compared with conventional anti vibration hammer, the hammer body design eliminates the deposition of water and ice, the anticorrosive rubber pad, the wire without fatigue, can reduce the loss of electrical performance; while using the preformed installation in the construction, without installation tools, improve the construction safety; and can keep constant torque, ensure no slide line phenomenon, safe and reliable operation; in electrical performance, because the preformed anti vibration hammer connected with the wire through the rubber pad, avoid direct contact, gradually less power loss. In addition, the preformed fixed hammer body, because it is not closed preformed, does not produce corona loss, has good energy saving effect.
【技术实现步骤摘要】
本技术属于一种高压输电线路配件,特别是一种预绞式防振锤。
技术介绍
高压输电线路微风振动主要使导线产生疲劳和磨损破坏。防振锤的使用可以有效 地减低应力组合,降低导线疲劳破坏,延长线路使用寿命。长期以来,传统防振锤重量重,外 形粗笨,无法消除水及冰的沉积,特别是采用螺栓安装,由于应力集中造成导地线断股,且 螺栓安装不能控制安装力度,无法保持恒定力矩,造成防振锤产生滑移现象,反而会对导地 线造成更大的损害。
技术实现思路
本技术的目的是提供一种预绞式防振锤,能降低由于传统防振锤夹板造成的 应力集中造成的断股现象,在提高握力同时增大接触面积,减少锤体掉落、防振锤滑线的现 象,并提高施工安全性。本技术提供的技术案如下它包括锤体,其特征是两个对称的锤体通过钢 绞线连接在线夹上,线夹上部呈挂钩形,线夹上部与电线接触部分设置防腐蚀橡胶垫,同时 设置预绞丝。安装时先将线夹与电线搭接,随后将搭接处用预绞丝缠绕即可,无需任何安装工 具。预绞式防振锤采用预绞丝来提供握力,增大了接触面积,应力分布分散,有利于减少应 力集中现象,从而降低由于应力集中造成的断股现象。同时,预绞丝结构设计具有 ...
