Abstract

The invention relates to a Chinese character feng-shaped power transmission iron tower with longitudinal wire frames and belongs to the technical field of power transmission and distribution engineering. Each longitudinal wire frame is additionally arranged at the extending end of an original cross bar of a tower head; each longitudinal wire frame is formed by a wire frame and a connection frame; the wire frame is formed by two flat frame surfaces up and down and two vertical frame surfaces front and back; each flat frame surface is formed by a wire frame main material, flat surface flat web members and flat surface oblique web members; each vertical frame surface is formed by a wire frame main material, vertical surface vertical web members and vertical surface oblique web members; end web members are arranged at two ends of the wire frame left and right; suspension wire insulator strings are hung on the two ends of the wire frame; the connection frame is formed by one flat connection surface and two vertical connection surfaces; the flat connection surface is formed by a connection frame main material, connection frame oblique web members and connection frame longitudinal web members; each vertical connection surface is formed by a connection frame main material, original cross bar oblique main materials and web members for connecting the connection frame main material with the original cross bar oblique main materials. One level of branch tower can be saved, lines of 200m can be saved, and the line transform is laborsaving and timesaving with less power off; the line corridor is narrow and the farmland occupation is less; the Chinese character feng-shaped power transmission iron tower with the longitudinal wire frame is mainly used for the branch-connection tower of a main branch line of a dual-return transmission line.

Description

The rich font electric power pylon that has longitudinal coil holder
Technical field
Power transmission and distribution project.
Background technology
Ultra-high-tension power transmission line, at the discrimination contact of main discrimination circuit, adopts π link mode, and technology maturation, is widely used.But this line mode needs 3 Ji Fenqita.Three Ji Ta build ground in, and main branch road wire connects, and from high-altitude, overlooks, and is used in the industry claim that π connects, actual likeness in form " V " word, and this just causes wire consumption large, and circuit corridor is wide, and floor space is many, and the reparation of ploughing is high.For saving line cost, saving occupies cultivated land, and shortens the construction period, need to have the circuit discrimination connection technology of science economy more.
Summary of the invention
The rich font electric power pylon that has longitudinal coil holder, the technical problem that solve is: with a Ji Fenqita, realize circuit discrimination and connect.The technical scheme adopting is: on the stringing cross-arm of the difference tower of main line, add longitudinal coil holder.
The rich font electric power pylon (Fig. 1) that has longitudinal coil holder is that the overhanging end at the former cross-arm A of tower head adds longitudinal coil holder.Longitudinally coil holder is comprised of coil holder and frame linking.Coil holder is comprised of two flatrack faces 5 and tandem two vertical frame faces 9 one on the other.Flatrack face 5 is comprised of the main material 6 of coil holder, the flat web member 7 of plane, plane diagonal web member 8.Vertical frame face 9 is comprised of the main material 6 of coil holder, the perpendicular web member 11 of vertical plane, vertical plane diagonal web member 10.Two of left and right of coil holder termination face has end web member 12.
Frame linking is comprised of a flat even face 1 and two perpendicular faces that connect.The flat face 1 that connects is comprised of the main material 4 of frame linking, frame linking diagonal web member 3, the vertical web member 2 of frame linking.Perpendicular even face is comprised of with the web member that is connected the two the oblique main material B of the main material 4 of frame linking, former cross-arm A.
Each main material is connected with each web member: form the direct-connected with bolt of two bar nodes; Form connecting by junction plate of the above node of three bars.
, respectively there are two insulator string strings two terminations, about coil holder, for hanging the wire of main discrimination circuit, and with wire jumper by main discrimination connection.
The coil holder flatrack face 5 of longitudinal coil holder of three cross-arms of upper, middle and lower is on cross-arm; The coil holder flatrack face 5 of longitudinal coil holder of earth wire rack is under earth wire rack.
There is the beneficial effect of the rich font electric power pylon of longitudinal coil holder to be: 1, to save a Ji Fenqita, save the circuit 200m between the first tower of two difference towers and discrimination line; Track remodelling power cut construction, can reduce by a construction point, shortens power off time, reduces dangerous spot.2, circuit corridor is narrow.3, occupy cultivated land less.
Accompanying drawing explanation
Fig. 1 is shown with longitudinal coil holder three-dimensional structure diagram of the rich font electric power pylon of longitudinal coil holder.
The specific embodiment
Coil holder adopts square truss.The interlude being connected with former cross-arm A adopts two web member frame faces; Two cantilever ends of hanging wire adopt single web member frame face.The flat face 1 that connects of frame linking adopts two web member structures; Two perpendicular faces that connect adopt single web member structure.Diagonal web member configuration orientation, tension while making it to carry.Insulator string is hung on many bars node.All the other structures of steel tower, inherit existing rich font iron tower structure.
