Description
Technical field
the present invention relates to ultra-high-tension power transmission line flexible windproof device technique field, is the windproof anchoring of a kind of ultra-high-tension power transmission line.
Background technology
because the Northwest's major part is positioned at middle-latitude zone, belong to continental stronger temperate zone arid climate, often there are polar region cold air mass invasion and attack, because earth's surface is dispersed with immense Gobi desert, desert, landforms are many to be made up of basin, valley floor, simultaneously because mountain pass, bottleneck are numerous, and ground elevation discrepancy in elevation great disparity, easily occur strong wind when cold air is invaded, and cardinal wind is comparatively fixing throughout the year.The ground such as " the three Shi Lifeng districts " of the such as northwestward, Turfan, " the Bai Lifeng district " of Hami ten three rooms one band, annual more than eight grades Windy Days were more than hundred days, prevailing wind is north wind, because extreme local strong convective weather often occurs, after the insulator windage yaw of transmission line, charged position and steel tower safe distance deficiency, easily cause power transmission circuit caused by windage trip accident.
