摘　　要：介绍了一起典型的110 kV电缆终端塔由于山火导致电缆受损的危急缺陷,由于电缆终端塔为同塔双回给一个110 kV变电站送电线路,急需解决缺陷否则易造成110 kV变电站全站失压的风险,因各方及时处理得当将影响及损失限制在最小范围内。文章通过对事故原因的分析,提供了针对性的消缺方案设计和缺陷消除过程,最后提出了类似缺陷的预防措施及建议,防止类似事故隐患的发生。This paper presents a typical case of a 110 kV cable terminal tower damaged by a mountain fire,which caused damage to the cable.Due to the fact that the cable terminal tower is a dual-circuit tower for supplying power to an 110 kV substation,it was urgent to solve the defect otherwise there was a risk of the entire 110 kV substation being lose voltage.Due to the timely and proper handling of all parties,the impact and loss are limited to a minimum range.Through the analysis of the cause of the accident,the paper provides the design of the defect elimination scheme and the process of the defect elimination,and finally puts forward the preventive measures and suggestions of similar defects to prevent the occurrence of similar accidents.
