基于提高电缆运行稳定性的目的,分析引起电缆故障的主要原因,通过加速电缆老化进程试验,再采用有限元分析法构建电缆温度场仿真模型,最后采用分布式光纤测温技术对电缆温度进行监测,可得知电缆温度与其绝缘老化进程有着密切的关系,经对比分析可知,在不同电流下,电缆温度的临界值也不同,例如流经的电流为100 A时,电缆内部温度为34.94℃,电缆护套温度为29.23℃,则超过此温度时会加速电缆老化,减少电缆寿命.

Based on the purpose of improving the stability of cable operation,to analyze the main cause of cables failure,do the accelerated cable aging process test,using finite element analysis method to construct cable temperature field simulation model,finally,the distributed fiber optic temperature measurement technology is used to monitor the cable temperature,and then,it can be known that the cable temperature is closely related to its insulation aging process,according to comparative analysis,the cable temperature threshold is different at differe...
