摘　　要：针对某换流站内GIS中发生的漏气故障进行宏观检查、渗透检测和受力分析,结果表明,本次漏气故障是由CT接线座开裂导致,采用不当的紧固工具或用力过大,造成不连续部位承受过大的弯曲应力,造成接线座开裂,提出的预防措施可供参考。In allusion to the gas leakage fault in the GIS of a converter station,analyses were conducted by macroscopic inspection,penetration test and force analysis.The results showed that the air leakage fault was caused by the cracking of CT wiring base.The use of improper fastening tools or excessive force brought about excessive bending stress on the discontinuous parts,resulting in the cracking of the wiring base,which is available for reference in putting forward preventive measures.
