电力电缆在输电线路中广泛应用，但由于电缆在工作时会因为过载等原因而发热升温，使其绝缘性能劣化，进而发展成为绝缘击穿乃至火灾，因此，对电缆温度进行在线监测具有重要意义。很多专家和学者对在线监测投入了较大的研究力度，目前，已经完成了基于分布式光纤光栅传感温度测量系统的大部分内容，相应的技术投入使用后，可在线监测获得较多的数据和信息，为电力电缆的应用提供更多的帮助。

The power cable is widely used in power transmission lines,but because the cable overload at work,or oth-er reasons heat up,the insulation performance degradation.And then develop into a insulation breakdown and even fire. Therefore,on-line monitoring of cable temperature is important significance.Many experts and scholars have invested a large research efforts in terms of on-line monitoring,and the result is more positive.Currently,most of the content has been completed based on the distributed FBG sensing temperature measurement system,after the appropriate use of tech-nology investment,online monitoring has made more data and information for the application of power cables,providing more help.
