(S) ОПОРА ЛИНИИ ЭЛЕКТРОПЕРЕДАЧИ(S) ELECTRICAL TRANSMISSION LINER

1one

Изобретение относитс к строительной части опор дл воздушных линий электропередачи высокого, сверхвысокого и ультравысокого напр жений .The invention relates to the construction part of supports for overhead, high, and ultra-high voltage overhead power lines.

Известна трехфазна одноцёпна воздушна лини , расщепленные фазы которой расположены по трем концентрическим окружност м. Эта лини обладает повышенной пропускной способностью 11.The three-phase single-circuit air line is known, the split phases of which are located in three concentric circles. This line has an increased carrying capacity 11.

Недостатком ее вл етс значительна металлоемкость.The disadvantage of it is a significant metal consumption.

Наиболее близкой к изобретению вл етс опора трехфазной одноцепной воздушной линии электропередачи с расщепленными фазами, расположенными по трем концентрическим окружност м, подвешенным с помощью изол торов, включающа три наклонных стойки опорной части, расположенные под углами 120 в плане, опирающиес на фундаменте , верхнюю стойку, сочлененную шарниром со стойками основани , и отт жки , прикрепл ющие верхнюю стойку к нижним концам наклонных стоек основани . Верхн стойка опоры представл ет собой две У-образные расход щиес стойки, верхние концы которых соединены гибкой св зью 21.Closest to the invention is a three-phase single-circuit overhead power transmission line with split phases arranged in three concentric circles suspended by insulators, including three inclined support legs located at angles 120 in plan, resting on the foundation, top stand articulated with the base posts, and straps securing the upper stand to the lower ends of the inclined base posts. The upper support leg consists of two Y-shaped divergent struts, the upper ends of which are connected by a flexible link 21.

Указанное выполнение верхней стойки увеличивает габариты опоры и ширину заливаемой опоры трассы, поэтому хот известна опора и вл етс The specified execution of the upper rack increases the dimensions of the support and the width of the track to be poured in, therefore, although the support is known

to экономичной, однако в ней не достиг нуто оптимально возможное при концентрическом расположением фаз уменьшение габаритов опоры.to economical, however, it did not achieve the optimal reduction of support dimensions with a concentric phase arrangement.

Цель изобретени - уменьшение га15 баритов и материалоемкости опоры.The purpose of the invention is to reduce ha15 of barite and support material consumption.

Указанна цель достигаетс тем, что в опоре линии электропередачи, включающей стойку, установленную на опорную часть в виде расход щихс This goal is achieved by the fact that in a power transmission line support, including a rack, mounted on the support part in the form of diverging

Claims

20 at an angle of 120 ° to each other of elements mounted on foundations, straps connecting the rack with points of support of the elements, additional straps arranged in a horizontal plane and forming a closed loop, concentrically arranged wires and insulators, the stand is made in the form rigid polygonal contour whose vertices are connected by insulators. The drawing shows schematically the support in the direction along the line, a general view. The support includes the upper rack 1 in the form of a rigid polygonal contour with clips 2 for fastening the braces, three elements of the bearing part 3, in plan located at angles of 120 °, foundations, such as surface binder link 5 with hinges 6, braces of the system of split wires of phases with three concentric rings and insulators of this example located in three diameters with an angle of 60 ° between adjacent radii. The lower part of the support is similar to the known support. In it, all braces can also be tensioned by a single talom pom, forces act on the axis of the base pillars, and the middle base of the base is located along the axis of the transmission line. In the example shown in the same line, the top rack is made in the form of a hexagon, but it can also be made in the form of eight, ten and quadrilaterals, depending on the brand of the number of wires in the phase and on the STRING (RIAR. A rigid polygonal contour, for example an equilateral, the opposite vertices of which are connected by insulators 17 and 18, for example, a glass of a lamellar y-; or made of wire insulators, and concentricly arranged split Tt-lS phases are attached to insulators; Rita (width and height) of the support, which reduces the consumption of materials of the support and the width of the line and increases the efficiency of the support. The intermediate support of the 750 kV line, having in phase 2 wires of the АС-300 brand in the second ice region and in the Y wind region has a height of 61 m and a width of 3 m provides an overall span of 5–5 m. A support weight of 65 tons, which takes into account the high line capacity (over 10 million kW), makes the transmission line highly economical. Invention Formula Transmission line support, mounted on a fixed hour In the form of elements disposed at an angle of 120 to each other, mounted on foundations, straps connecting the rack with points of bearing, additional strands located in a horizontal plane and forming a closed loop, concentrically arranged wires and insulators, And so that, in order to reduce the size and material of the support, the stand is made in the form of a rigid polygonal contour, the vertices of which are connected by insulators.
