Description
Technical field
The utility model relates to fastening or fixed component technology, especially the power transmission line wind bracing wire cross arm device in the F16B2/06 transmission line.
Background technology
In known technology, the wind sex climate is threatening the safe operation of grid power transmission circuit always, the transmission line caused because of high wind and sandstorm falls the accidents such as shaft tower, windage yaw, the de-string of insulator and gold utensil fracture and happens occasionally, wherein especially so that windage yaw is high to the harm frequency of transmission line, scope wide, the degree weight.In recent years, diastrous weather takes place frequently, and part power transmission circuit caused by windage fault significantly rises, and has become the key factor that affects electric power netting safe running.Improving technical scheme discloses less.
The bracing wire buttock line of 201,120,499,436 1 kinds of power transmission line column bars of Chinese patent application and this line tying fixture, comprise the U-shaped frame, be placed with grip block on the lower shoe of U-shaped frame, clamping screw is connected in grip block through the lower shoe active card, clamping screw and lower shoe threaded engagement, screw clamping screw and can promote the grip block traveling priority that makes progress.
The utility model content
The purpose of this utility model is to provide power transmission line wind bracing wire cross arm device, strengthens contacting between cable and transmission tower, reduces the pneumatic windage yaw arcing fault caused.
The purpose of this utility model realizes by following technical measures: connect windproof bracing wire under the catenary string, connect windproof cross-arm under windproof bracing wire.
The beneficial effects of the utility model are: the windproof cross-arm of design and anchoring on shaft tower, with succinct structure, reduce the probability that the windage yaw accident occurs, improve the transmission line safety operation level, reduce energy loss, be easy to manufacture, installation and maintenance, handsome in appearance, durable, applicability is strong, economical convenient.

Embodiment
Below in conjunction with drawings and Examples, further illustrate.
Embodiment 1: as shown in Figure 1, the catenary string connects windproof bracing wire 2 for 1 time, and windproof bracing wire connects windproof cross-arm 3 for 2 times.Windproof cross-arm 3 is horizontally fixed on electric power pylon 5.
In aforementioned, electric power pylon 5 strain towers or steel tower; Catenary string 1 is by 2 groups of strain tower jumper string lower ends difference connecting cross beams, the symmetrical suspension in these crossbeam two ends cable 4; Catenary string 1 upper end is arranged on the strain tower top, catenary string 1 lower end connects one group of windproof bracing wire 2 by connecting plate, windproof bracing wire 2 lower ends are by the windproof cross-arm 3 of connecting plate both sides chain connection, and windproof cross-arm 3 is horizontally fixed on strain tower or steel tower class electric power pylon 5.
Embodiment 2: as shown in Figure 2, and electric power pylon 5 tangent towers; Catenary string 1 connects 1 group of windproof bracing wire 2 by 1 group of suspension string lower end by connecting plate, and under this connecting plate, middle side part hangs and takes over control wind bracing wire 2 by hinge, the symmetrical cable 4 that hangs in these connecting plate two ends; Vertical line string 1 upper end is arranged on the tangent tower top, and catenary string 1 lower end connects windproof bracing wire 2 lower ends by the windproof cross-arm 3 of connecting plate both sides chain connection by connecting plate, and windproof cross-arm 3 is horizontally fixed on tangent tower electric power pylon 5 middle parts.
As shown in Figure 3, fixing hole 6 is opened, two ends fixed connecting base 7 in windproof cross-arm 3 middle parts.Windproof cross-arm 3 is arranged on electric power pylon 5 by fixing hole 6, and windproof cross-arm 3 is by Connection Block 7 fixing windproof bracing wire 2 lower ends.
As shown in Figure 4, windproof cross-arm 3 is horizontally fixed on tangent tower electric power pylon 5 middle parts, and windproof cross-arm 3 tops connect 3 groups of catenary strings 1 and windproof bracing wire 2, and the upper end of these 3 groups of catenary strings 1 is separately fixed at tangent tower electric power pylon 5 upper ends.3 or 6 groups of cables 4 are suspended on respectively between catenary string 1 and windproof bracing wire 2, and when meeting with strong wind, 2 pairs of cables of installing therebetween of catenary string 1 and windproof bracing wire 4 produce effect of draggings, to reduce, to weaken or to overcome the windage yaw flashover.
In the utility model, after windproof bracing wire and windproof cross-arm are installed, the power transmission circuit caused by windage trip-out rate reduces greatly, and energy-conservation a large amount of electric energy, improved power supply reliability.According to every transmission line tripping operation in every year, trip 20 hours at every turn, the economic transmission capacity of 220kV transmission line is 262MVA, electricity price is according to 0.25 yuan of Xinjiang rate for incorporation into the power network/degree, 1,310,000 yuan of annual cost savings.The region, Xinjiang is wide, only, according to annual 10 line trippings, can save 1,310 ten thousand yuan every year.
