一种架空导线、地线拉力试验工装研制

Development of a Tensile Test Tool for Overhead Conductor and Ground Wire

本文主要介绍型号为LAW-1000卧式拉力试验机进行导线、地线拉力试验夹具工装的设计特点、计算原理,并按照GB/T4909.3-2009《裸电线试验方法拉力试验》的要求使用试验工装进行大量试验,验证夹具的合理性。

In this article,we mainly introduce the design characteristics and calculation principle of the fi xture device for wire and ground wire tension test with LAW-1000 horizontal tensile testing machine,and use the test device to carry out a large number of experiments according to the requirements of GB/T 2317.1-2008<test method for electric power fi ttings Part I:mechanical test>to verify the rationality of the experiments fi xture.
