Description

technical field [0001] The invention is a 500kV compact power transmission line three-phase split wire breeze vibration simulation test platform. Background technique [0002] In the construction of my country's power grid, with the rapid growth of my country's power transmission capacity, it has become an inevitable choice to choose multi-split, large-capacity, and long-distance transmission lines. And due to the limitation of line corridors, compact transmission lines have attracted much attention in the construction of ultra-high voltage power grids. With the emergence of more and more compact transmission lines with high voltage levels, the wires in the lines are often affected by wind, ice, low temperature and other meteorological conditions, and breeze vibrations often occur. It causes accidents such as wire breakage, wire breakage, damage to interphase spacer connecting hardware, phase short circuit, etc., which seriously threatens the safe operation of transmission ...

AI Technical Summary

Problems solved by technology

The direct reason is that there has been no "500kV compact transmission line three-phase split conductor breeze vibration simulation test platform", to carry out breeze vibration fatigue test research and wind vibration resistance test research on the overall interphase spacer, but to use the overall interphase spacer The interphase spacer body and the interphase spacer connecting fittings are separated, and the breeze vibration fatigue test and the breeze vibration resistance performance test are respectively carried out. The actual operating state of the breeze vibration of the three-phase split conductor of the 500kV compact transmission line is not simulated, which makes the simulation lack authenticity , the simulation results have a large error with the actual situation
