摘　　要：通过对某省公司17座变电站110 k V GIS母线筒焊缝开裂缺陷的现场监测,以及裂纹分布形式、产生机理的研究及有限元分析,找出了GIS母线筒焊缝开裂的主要原因并制定了相应的整改措施,经2年的监测运行效果显著。Based on the field monitoring data of the weld seam cracks on the 110 kV GIS bus tubes in 17 substations,the crack distribution and the cracking mechanism are researched and a finite element analysis for the cracking mechanism is made in this paper and then the primary cause for the welding seam cracking and the targeted improvement measures are also given which has been validated effective by the monitoring for two years.
