Description
Technical field
the present invention relates to ultra-high-tension power transmission line flexible windproof device technique field, is a kind of ultra-high-tension power transmission line windproof ground puller system.
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.
such as 750kV tells Kazakhstan one, two wires ultra-high-tension power transmission line, this one, the parallel erection in two wires, be east-west completely, the sea level on the average 1000m of the multiple section of fault of distance Shanshan County, In Turfan In Xinjiang about 60 km, its landform is Gobi desert, climate type is strong wind weather, and long-term prevailing wind is northwester.Tool is calculated on the spot, and on-the-spot 10 meters of height 10 minutes average maximum wind velocity 36m/s, wind direction is north wind, and wind direction and wire angle are 75 degree to 90 degree.Through windage yaw calculation and check, during 28m/s wind speed, maximum angle of wind deflection is 54 degree, and the nearest clearance of distance steel tower is 2.96 meters, meets the requirement of power frequency electric clearance 1.9 meters; During 36m/s wind speed, maximum angle of wind deflection is 66 degree, and the nearest clearance of distance steel tower is 1.5 meters, does not meet the requirement in 1.9 meters, power frequency electric gas gap, therefore than being easier to, windage yaw trip accident occurs.
windage yaw trip accident affects greatly electric power netting safe running, in order to solve circuit windage yaw trip problem, existing prophylactico-therapeutic measures is generally the weight directly installing some at the insulator string of pendency additional, wish by reducing the skew of wire under high wind conditions after insulator string weightening finish, to avoid live wire, iron tower construction member is discharged, but during actual implementation the method, because the intensity of corresponding gold utensil and insulator limits, counterweight is relatively limited, and after installing weight additional self still can there is larger beat or rotation in insulator string under high wind conditions, cause the gold utensil deflection angle bearing wire larger, therefore suppress the effect of wire windage yaw unsatisfactory, at present in the urgent need to a kind of reliability, operability, the wind deflection preventive of better economy.
