摘要
介绍了一起220 kV电缆户外终端发热缺陷的分析处理。通过对户外终端进行红外测温发现终端发热缺陷,停电后解剖终端套管,通过有限元分析对电缆户外终端电场和温度进行仿真,明确终端发热的主要原因,提出了预防类似缺陷产生的措施及建议。
The analysis and treatment of overheating defects in outdoor terminal of 220 k V cable is introduced. The terminal overheating defect is revealed by infrared temperature measurement of outdoor terminals,and the terminal bushing is dissected after power outage. The main reasons of overheating defect are defined by the simulation of cable outdoor terminal electric field and temperature using finite element analysis,and the preventive measures and suggestions about similar defects are put forward.
