Abstract

The transmission line has been affected by the natural environment for a long time, and the bolts are prone to frequent vibration, resulting in loosening or falling off. This paper analyzes the loosening mechanism of the screw connection of the transmission tower, carries out the transverse vibration contrast test of the commonly used bolt anti-loosening measures, and compares and analyzes the commonly used bolt anti-loosening performance test standards at home and abroad. Based on the importance of the transmission line and the different operating environment, the grading criteria and differential anti-loosening methods of the transmission tower bolt anti-loosening performance are proposed.
