摘要

XPLE电力电缆因其优异的机械性能和电绝缘性能得到广泛的使用

在交联电缆接头安装过程中

对交联聚乙烯主绝缘表面进行打磨会使接头交联聚乙烯—硅橡胶界面产生不同的粗糙程度

但是对存在于两个有机绝缘之间的接触面的电绝缘强度的研究很少

笔者针对交联聚乙烯电力电缆接头的交联聚乙烯和硅橡胶两绝缘界面经常出现放电光的现象

建立了电痕破坏实验平台

用不同型号的砂纸对XPLE片横向和纵向打磨制备实验样品

采用高速相机对发生在交联聚乙烯和透明硅橡胶界面上的放电光进行记录。结果表明:界面粗糙度越大

则发生放电光时的起始电压越低

放电光强度越大

界面绝缘性能越差;纵向打磨界面放电光强度比横向打磨强

纵向打磨界面放电光绝缘性能较弱。

Abstract

XPLE is widely used because of its steady mechanical property and insulation performance.While setting XLPE-Silicon-rubber cable joint

roughness occur on the interface between XLPE and silicon rubber.But it is very little to research the dielectric performance on the interface.This paper studies the distributing characteristics of discharge light on the interface

sets up test-bed

prepares pattern by using different kinds of sand paper

measures the light on the interface by using high speed camera.The results indicate that: the greater the interface roughness is

the lower the initial voltage is when the discharge light occur;and the greater the discharge light intensity is

which prove the interface insulation perfomance is worse;the light intensity of vertical grinding interface is stronger than the horizontal

which testify that the front interface insulation performance is worse than the back.
