摘要

针对某变电站GIS设备现场安装过程中发现某段导体回路电阻严重超标的问题

对GIS变电站内的导体进行现场解体

发现直线导体有裂纹。通过对该导体样品进行理化性能试验、断口宏观分析、金相分析、电镜及能谱分析等试验。结合该导体在安装过程中出现的状况

得出该直线导体开裂属于晶间解理脆性断裂

是由于厂家工艺粗糙、焊接工艺不良而导致。

Abstract

Aiming to the very high circuit resistance of a conductor during installation in a GIS substation

the conductor was disassembled and disintegrations were found. Experiments are carried out such as the physicochemical properties

fracture macro-analysis

metallographic analysis

electron microscopy and EDS analysis. Such disintegration is cleavage to intergranular brittle fracture and it is caused by rough manufacturing process and bad welding process.
