Description
При расчете конструкций промежуточных опор линий электропередач -величина давлени ветра на провода имеет существенное значение. Коэффициент лобового сопротивлени зависит от формы поверхности, на которую действует ветер, и дл круглых проводов он значительно больше, чем дл овальных или эллиптических.When calculating the structures of intermediate supports of power lines, the magnitude of the wind pressure on the wires is essential. The drag coefficient depends on the shape of the surface on which the wind acts, and for round wires it is much larger than for oval or elliptical ones.
Дл снижени величины этого коэффициента предлагаетс сталеалюминиевым проводам дл линий электропередач придавать овальное или эллиптическое сечение, обеспечивающее более благопри тные услови дл обтекаемости.To reduce this coefficient, it is proposed to use steel-aluminum wires for power lines to impart an oval or elliptical cross-section, providing more favorable conditions for streamlining.
Правильное расположение предлагаемого провода при подвеске обеспечиваетс двум стальными сердечниками, скрученными в противоположных направлени х, и дистанционными распорками в лини х с расщепленными проводами в каждой фазе.Correct positioning of the proposed wire during suspension is provided by two steel cores twisted in opposite directions and spacers in the lines with split wires in each phase.
На чертеже схематически изображен сталеалюминиевый провод в разрезе и прин ты следующие обозначени : / - алюминиевые жилы, 2- стальные жилы, образующие два стальных сердечника, скрученных в противоположных направлени х, 3 - жгут.The drawing shows schematically a steel-aluminum wire in a section and the following notation is adopted: / - aluminum conductors, 2- steel conductors, forming two steel cores, twisted in opposite directions, 3 - tow.
Предмет изобретени Subject invention
Сталеалюминиевый электрический провод, отличающийс тем, что он имеет овальное или эллиптическое сечение и снабжен-двум стальными сердечниками, скрученными в противоположных направлени х, с целью снижени лобовой ветровой нагрузки на провод и предотвращени его скручивани .Steel-aluminum electrical wire, characterized in that it has an oval or elliptical cross section and is provided with two steel cores twisted in opposite directions in order to reduce the frontal wind load on the wire and prevent it from twisting.
