Abstract
Typhoon wind loads acting on transmission line wires include horizontal wind loads,vertical wind load composed of longitudinal wind force and upward suction force,and the vertical wind load is opposite to the direction of the self-gravity of the wire.However,in the current wind load design of transmission lines wire,only the horizontal wind speed of typhoon is taken as the maximum wind speed,and the influence of vertical wind load is not considered,and there are design loophole.This paper analyzes the typhoon wind load of transmission line wire,proposes a simplified design method of vertical wind load for typhoon,and applies it to the design of typhoon swing angle of insulator string of transmission line.The vertical wind load is approximately equal to 10%～20%of the horizontal wind load of typhoon.The calculation example of 220 kV line shows that considering the influence of vertical wind load,the wind swing angle of insulator string increases by 7%～15%,and typhoon rainstorm flashover may occur from transverse to tower and longitudinal to cross arm.Ignoring vertical wind load may be the reason that the swing angle of the existing insulator string is not typhoon rainstorm-resistant.关键词
