Description

technical field [0001] The invention belongs to the technical field of experimental devices, and relates to a three-dimensional space loading device, in particular to a three-dimensional space variable angle loading device. Background technique [0002] In the traditional power transmission and substation industry, overhead transmission towers or substation structures are mainly composed of towers and hanging beams. Early hanging beams used angle steel composite trusses, but due to the good electrical conductivity of steel, lightning strikes and Line tripping faults caused by pollution flashover account for more than 60% of the total tripping faults of overhead transmission lines each year, which has greatly troubled and affected the safe, economical and stable operation of the power grid for a long time. In areas with serious pollution (salt pollution), it is even more serious. In recent years, due to the advantages of light weight, high strength, good insulation performan...
