摘要
对某电厂升压站500 kV线路螺栓断裂事故进行分析,认为该螺栓因用材不当和表面加工质量不符合要求,且长期在腐蚀性环境中使用并承受交变弯曲应力作用,导致其发生腐蚀性疲劳断裂。
This paper analysis the failure of a bolt on 500kV transmission line in one booster station of a Power plant,and shows that inappropriate material,surface processing quality doesn't meet requirements,and long-term use in corrosive environments and under alternating bending stress lead to corrosion fatigue fracture.
