Description
Technical field:
The utility model relates to a kind of overhead wire shaft tower device that is used for industrial and mining enterprises' power delivery networks.
Background technology:
At present, the transmission of electricity core network that industrial and mining enterprises adopt mostly is the 66KV overhead wire greatly, and this kind overhead wire has the branch of single pole (tower) single time, single pole (tower) two times, single pole (tower) many times again.In the design and construction of circuit, according to designing requirements such as power supply, load position, circuit length, the circuit scissors crossing of 66KV overhead wire and other electric pressure is inevitable.Electric power rules regulation: the overhead wire No striding voltage levels overhead wire of low-voltage grade.When the lower wire height off the ground of voltage levels circuit (as the 220V overhead wire) hangs down (as 12 meters), 66KV overhead wire (as the 220KV overhead wire) should guarantee the safe distance to the 220KV overhead wire, guarantee safe distance over the ground again, pass through just very difficult.In detailed programs, there is a 66KV single pole (tower) double loop to intersect with the 220KV overhead wire, design difficulty is bigger.The arrangements of conductors mode of the two telegram in reply power iron towers of existing typing 66KV is that cydariform is arranged, and the upper conductor minimum altitude is 14m, can not satisfy and pass through designing requirement.To this, the on-the-spot solution that adopts usually is: double-circuit line is split as two single backwater horizontal line roads, adopts door type electric pole to realize passing through again.Though this way can realize passing through, but shortcoming is also clearly: a door type electric pole adopt two with the footpath concurrent as principal post, be equipped with angle steel cross-arm, fork beam, 8 and lead (line) backguy (line), not only take up an area of big, and electric pole is perishable, backguy is easily artificially damaged, and safety is low, simultaneously, adopt 4 groups of door type electric poles to realize passing through, increased the width of circuit route, line route is required harshness more, versatility is poor.
The utility model content:
The utility model purpose purpose is to provide that a kind of floor space is little, the not perishable or artificial damage of body of the tower, the flat iron tower that passes through of the two backwater of 66KV overhead transmission line safe and highly versatile.
The utility model is achieved in that the two backwater of this kind overhead transmission line are flat and passes through iron tower and comprise lightning protection system, wiring system and body of the tower three parts, lightning protection system and wiring system are installed in body of the tower top and top respectively, and the arrangements of conductors of body of the tower both sides is two backwater flat raft row.Wherein, lightning protection system is made up of lightning conducter, lightning conducter hanging wire point and lightning conducter cross-arm, and the lightning conducter cross-arm is mounted on the body of the tower top, lightning conducter with the body of the tower be center line symmetrically with about two lightning conducter hanging wire points be connected.Wiring system is made up of lead cross-arm, hanging wire point and lead, the lead cross-arm is installed in body of the tower top, cross-arm each side is provided with 3 hanging wire points, each hanging wire point is that center line is symmetrical with the body of the tower, trend and the perpendicular lead of cross-arm are set respectively on each hanging wire point, 6 lead trends are parallel to each other, and it is horizontal to be the double loop.Body of the tower adopts 7719 (9) type 66KV double loop cydariform strain insulator corner overhead wire iron towers.This kind iron tower of power transmission line need pass through according to the actual intersection of overhead power line when reality is used and require to carry out working design, maximum duty load according to lead designs lead cross-arm truss cross section and structure, design separation according to lead span, sag, and then level interval and lead cross-arm length between definite lead hanging wire point, and check cross-arm truss sectional dimension and structural strength; Determine lightning conducter cross-arm length according to the lightning protection angle; according to actual maximum duty load design lightning conducter cross-arm truss cross section and structure; according to the clearance of line span check lightning conducter and lead, check iron tower main material and basic stress according to actual lead wire and earth wire maximum duty load.
The utility model is reasonable in design, and reliable operation is compared with existing door type electric pole group, and the iron tower foundation floor space is little, and line route is selected there is not specific (special) requirements, and body of the tower is not perishable or be subjected to artificial destruction, and electrical security and versatility improve greatly.
