Abstract
The conductor breeze vibration lasts for a long time, and the outlet conductor of the end of the conductor clamp is continuously subjected to dynamic bending, resulting in fatigue strand breakage. Especially for the lines in the low temperature and cold regions, the conductor tension is large and the suspension point is high. The problem of conductor breeze vibration strand breakage is more serious, causing certain damage to the conductor, line fittings and tower components. It is difficult to find out the prevention and control methods， routine inspection also has some difficulties. In the operation and maintenance of the line, it is not only necessary to obtain theoretical support such as simulation, but also more necessary to carry out on-site measurement to evaluate the risk possibility of the operation line. In this paper, through the study of the conductor breeze vibration, the on-site vibration measurement method based on Doppler laser is proposed. It provides a manner for the future development of long-distance non-contact live detection of conductor breeze vibration of transmission lines. The feasibility and correctness of the detection method are verified by the actual detection of transmission lines.
