A Design Method of Transmission Line Sag Measurement Robot

Traditional transmission line sag measurement method based on manual is affected by objective factors such as terrain, weather and span, and has certain limitations in some environments. This paper presents a design method of sag measurement robot which can move directly on the transmission line to measure transmission line sag in real time, including design requirements, overall structure, control system, work flow, sag calculation and application. Finally, the application of robot in transmission line construction is introduced, and compared with the traditional measurement results, from a qualitative perspective, this method is more flexible, convenient and objective than the traditional measurement method, and the measurement accuracy can meet the requirements.
