摘要
电力电缆线路运行温度在线检测技术是当前及时发现电力电缆线路的局部过热点位置、检测运行线路的绝缘状态、计算导体载流量的首选技术措施。为此,基于光频域反射OFDR测温法研究了一种能实现长距离大范围的新型测温技术——分布式光纤测温技术,实现了电缆温度的实时测量,并探讨了使用测温技术进行绝缘在线监测的可能性。
The first measure for preventing power cable failure is the online monitoring technology of operation temperature for power cable line,which can in time discover the local location of heat spot of power cable line,detect the insulation state of line,and calculate current-carrying capacity of conductor.Therefore,based on OFDR method,a kind of new technology-distributed optical fiber temperature measurement technology was studied,and the real time cable temperature measurement was realized.And the possibility...
