Research of Condition Monitoring of Transmission Lines in Non-Ice Coating Period Based on Optical Fiber Sensing

在OPGW直流融冰监测技术研究的基础上,我们基于光纤传感技术对非覆冰期高压输电线路状态监测进行了研究,以提高输电线路状态综合检测的丰富性及投资效用。主要对非覆冰期超高压输电线路所受应力、温度两个主要外界影响因素进行研究,实验结果表明,基于光纤传感的非覆冰期输电线路状态监测技术可以有效的对这两种外界环境进行识别。

Based on the research of OPGW DC ice-melting monitoring technology, we studied the condition monitoring of high-voltage transmission lines in non-Ice-covered period based on optical fiber sensing technology to improve the richness and investment utility of comprehensive detection of transmission line status. The main external influencing factors of stress and temperature in the non-Ice-covered EHV transmission line are studied. Experimental results show that the non-Ice-coating transmission line condition monitoring technology based on optical fiber sensing can effectively identify these two external environments.
