The specific embodiment
As shown in Fig. 1,2,3,5, the utility model is that a kind of 35kV transmission line of electricity single loop T connects steel tower, comprise pylon, one secondary strain cross arm 1 is installed on this pylon, (pylon on) above this strain cross arm 1, ground wire cross-arm 2 is installed, and (pylon on) is provided with a T and connects drainage cross-arm 3 below this strain cross arm 1, and this T to connect drainage cross-arm 3 vertical with described strain cross arm 1, to connect drainage cross-arm 3 be 90 ° with body strain cross arm 1 angle to T.At strain cross arm 1, ground wire cross-arm 2, T, connect and on drainage cross-arm 3, be respectively equipped with hanging wire hole in addition, specifically at the T of ground wire cross-arm 2, connect and in direction, be provided with hanging wire hole, and connect in direction and be also respectively equipped with hanging wire hole at the T that ground wire cross-arm 2 and T connect drainage cross-arm 3, the hanging wire hole on ground wire cross-arm 2 is positioned in its main material directrix in addition.
As shown in Fig. 3,5, using method of the present utility model is:
1) take certain wind energy turbine set 35kv current collection line project is example, first at main line, on the most rational position of blower fan, selects a T node, is the position that T connects tower, if landform is bad, moves forward and backward, and T connects direction hanging wire can be with 0-20 degree corner.
2) main line front and back crosspiece is determined bar position by normal span.
3) T connects direction circuit and by normal span, bar position is determined.
4) fitting, insulator on main line, hang wire.
5) fitting on T link.Insulator, hangs wire.
6) utilize drainage thread that main line is connected with the lead wire and earth wire that T connects direction.
The technical solution of the utility model also has following beneficial effect:
1) save shaft tower, lead wire and earth wire, insulator and gold utensil quantity.Especially wind-power electricity generation development is swift and violent for national new forms of energy in recent years, and wind-power electricity generation project is more and more, and wherein wind energy turbine set 35kv current collection line project is more and more.35kv current collection line route is fork-shaped and distributes, and T contact is intensive.Design in the past needs to adopt two base tension-resistant rods could realize T and connects requirement.If adopt single tower T to connect saving one base strain rod tower, the wire of one grade of line (T connects shelves), saves six groups of strain insulator strings and corresponding annex.
2) reduced industry workload in electric specialty.Conventional two bar T connect electric specialty and need connect according to different T height and isolated shelves length and go out the stringing table that T connects shelves stringing curve and shaft tower detailed statement are set.If adopt single tower T to connect, T connect shelves can be directly routinely safety factor arrange bar position.Greatly reduced electrical installation amount.
3) exploration and electric specialty field process amount have been reduced.If adopt single tower T to connect, T connecting point position can be definite at any time in conjunction with main line and T link, and even main line and T connection side all can be with certain corners.Field operation determines that T connects scheme can be simple and convenient, greatly improves field operation work efficiency.
4) wind energy turbine set roading and current collection line route are selected more flexibly initiatively.Wind field road and wind field are sent line route and are had certain plyability, and traditional T connects that grade occupation of land scope is large, lateral separation is wide, distance to the ground is little, all affected wind field roading, and adopting T to connect after tower, the problem that affects roading due to T contact can solve completely.
5) reduce and take up an area, meet the construction theory of amphitypy.Resources conservation, eco-friendly design concept run through whole engineering construction.Conventional two bar T connect the electric pole that scheme bracing wire and T connect side will take a large amount of soils.Make troubles also to wind field reallocation of land utilization.Single tower T connect rear track plan and path succinct.Greatly improved land utilization efficiency.
