Experimental Investigation on LGJ-400/50 ACSR Surface Erosion Characteristics in Wind Sand Environment

Abstract:

Surface state of transmission line is an important factor to the corona characteristics. Therefore, this paper using surface roughness as the experimental parameters, using Aluminum Conductor Steel Reinforced cable LGJ-400/50 as the experimental materials in wind sand environment, studied the effect of sand particles on the surface of LGJ-400/50 Aluminum Conductor Steel Reinforced cable though the wind tunnel experiment. According to the experimental results a line chart about roughness changing along with the erosion time is obtained. By using Matlab least square fitting function make the line chart into a curve so that trends can be clearly reflected. The results show that: (1) the curve can be divided into two parts: the fast rising stage and the stable stage, the stable stage is related to the formation of oxide layer; (2) when the attack angle is 30 ° surface erosion is the most serious and changes of surface roughness have a maximum value.
