Description
Technical field
It the utility model is related to power transmission line equipment technical field, and in particular to a kind of anti-bird pest cross-arm of 10KV circuits.
Background technology
With reinforcement of the mankind to awareness of natural ecological environment protection, the implementation prohibited hunting with multi-line regression model, Ren Leiwei
Birds existence creates more preferable environment, and the species and quantity of bird gradually increase, and scope of activities also progressively expands.With power network
Development, for transmission line of electricity if do not taken targetedly anti-bird measure, its extent of injury also will increase.Birds are nested on transmission line of electricity
When, mouth hold that the objects such as branch, iron wire, faggot are empty on the line in the month or wire between fly, hold object in the month during flight and drop in cross-arm
Between wire, or during extension wind, after the Bird's Nest on shaft tower is blown to four winds, object of nesting drops on live wire or insulator
Line short can be caused.Birds droppings can adhere to transmission line insulator surface in humid conditions, and its soluble substance is gradually dissolved in water,
Insulating surface forms one layer of conducting film, makes the dielectric level of insulator reduce, and it is existing to occur strong electric discharge under electric power magnetic fields
As causing the flashover of circuit, influenceing the safe operation of transmission line of electricity.Bird-caused Fault can cause the generation of large area blackout,
Directly influence the safety and stability and reliable power supply of power network.
Prevention birds build Bird's Nest on the cross-arm of 10kV power circuits turns into a great problem.Power department takes a large amount of people
Power material resources go line walking to remove bird's nest, and some also needs to power failure and goes to clear up, and has had a strong impact on power supply reliability.Bird pest is to jeopardize transmission of electricity
How one of major failure of line security operation, therefore, effectively take precautions against, to ensuring that transmission line safety operation has important meaning
Justice.At present, existing anti-bird measure has flag of being hung up red festoons in head of mast, installation windbell, reflective windmill, plastics windmill etc..This method
It is simple and easy, but long-term anti-bird measure is poor.Bird-resistant is installed, control bird inhabites position, positive effect, but operating maintenance equipment is stranded
It is difficult.Bird-proof cover is installed, easily come off.
The variously-shaped cross-arm often used in power circuit, typically two angle loads are combined with drift bolt and parallels
And formed.Nest is built thereon because the structure construction of this kind of cross-arm is easy to birds, and building for these Bird's Nests is often made
Into ground connection or breaking accident.It is always a problem for perplexing power department that small bird builds Bird's Nest on cross arm of tower, particularly
We are more and more in promotion ecological balance protection birds, this phenomenon now.Often cause line tripping, have a strong impact on
Power circuit it is safe for operation.On the cross-arm of 10KV power circuits, we are frequently seen Bird's Nest.These Bird's Nests are typically all to like
Magpie nest.Magpie is the stronger birds of adaptability, likes Bird's Nest to build on tall trees or the cross-arm of 10KV power circuits
On.
The patent of Application No. 200320107233.9 discloses a kind of power transmission line cross-arm of anti-bird pest, is to understand
Certainly birds present in prior art are easily nested on cross-arm so as to cause this technical problem of wire short-circuiting.The utility model is led to
Following technical scheme is crossed to be achieved：The top surface of the power transmission line cross-arm of this anti-bird pest is the inclined-plane tilted down.Due to this
Utility model uses said structure so that birds can not nest on cross-arm, cause so as to efficiently avoid due to Bird's Nest
Short circuit accident generation；In addition, by setting pointed cone in cross-arm top surface, birds are prevented to be stopped on cross-arm；In addition, in horizontal stroke
The fixing end of load is provided with fixed block, and fixed block is provided with fixation screw, is relatively fixed when by two cross-arms when on steel tower, only
It need to be fixed with screw through this screw, it is simple in construction, it is easy to loading and unloading, but the anti-bird pest effect of the utility model is not very bright
It is aobvious.
