Analysis and Research on Windproof Deviation of Coastal 500kV Transmission Line Jumpers

Abstract Based on the current situation of frequent wind deflection faults of 500 kV transmission line jumpers caused by typhoons in coastal areas, this paper proposes a new sectional wind deflection proof post insulator transformation measure by analyzing the advantages and disadvantages of conventional jumper wind deflection transformation measures, which effectively improves the anti typhoon and wind resistance of 500 kV transmission line jumpers. It can save the amount of steel for tower transformation and greatly shorten the transformation outage time. It provides a solution for future coastal transmission line construction and wind deflection prevention reconstruction.
