GIS设备导体缺陷X射线数字成像检测及缺陷产生原因分析

Detection of GIS Equipment Conductor Defects by X-ray Digital Imaging and Analysis of Defect Causes

采用X射线数字成像系统对气体绝缘金属封闭开关变电站(GIS)设备导体进行检测,发现导体焊接部位存在裂纹、未熔合等缺陷。经解体检查,X射线数字成像结果与实物缺陷一致。同时,理化试验结果表明,焊接工艺不当是导致导体产生缺陷的根本原因,并提出相应的解决措施。

By using X-ray digital imaging system,the test on GIS equipment conductor found some defects on welded parts of the conductor,such as cracks and incomplete fusion .After disintegrating,the X-ray digital imaging result is consistent with the physical defects.Meanwhile,the results of the physical and chemical test show that the improper welding process is the root cause of defects of the conductor,and following that appropriate solutions are proposed.
