The failures such as foreign body, tree line contradiction, bird pest, circuit are susceptible to because of which yet with the bare conductor of 10KV overhead transmission lines
Progressively replaced by insulated conductor.As insulated conductor has the resistance to thunder level of congenital defect, it is difficult to bear direct thunder or induced lightening
Effect, lightning-caused breaking already become a new difficult problem.Accordingly, it would be desirable to protect insulated conductor using lightning protection hardware.
But in the research and discussion for anti-bird pest and Lightning Protection, find the electric pole gold utensil of existing lightning-protection bird pest
Effect is all undesirable, and accident still can occur anti-bird anti-lightning strike electric pole is provided with.Therefore, design a kind of with integrated lightning protection
The electric pole armour clamp assembly of anti-bird pest, can directly reduce the failure of distribution line, provide strong for circuit even running
Ensure.
Utility model content
The purpose of this utility model is to overcome the deficiencies in the prior art, there is provided a kind of horizontal stroke with anti-bird pest structure function
Load lightning protection external member, the external member greatly reduce the bird pest problem of 10KV transmission lines of electricity, reduce because the power-off that bird pest causes is overhauled
Number of times, reduces the probability of direct lightning strike lightning-caused breaking, reduces the cost of power operation.
The technical solution of the utility model is as follows：A kind of cross-arm lightning protection external member with anti-bird pest structure function, including electricity
Line bar, which also includes cross-arm, bird-proof cover, bird thorn bar and protective cover, and the cross-arm is made up of first face and Article 2 face, first
The angle formed between bar face and Article 2 face is α, and insulator chain is also equipped with cross-arm, and cross-arm is fixed on electricity by anchor ear
In line bar, the upper surface of the bird thorn bar is provided with some steel thorns, and bird thorn bar is installed on first face, and the bird-proof cover is caged
Structure, bird-proof cover are installed on the central authorities of cross-arm by fixing bolt, and the protective cover is sheathed on electric pole top by anchor ear, prevent
Discharging rod is additionally provided with the top of shield.
Preferably, some perforates are additionally provided with cross-arm, rear reflector is installed in perforate, the rear reflector is conducive to reflection
Sunlight, reduces birds and has a rest the probability of electric pole.
Preferably, the angle α between first face and Article 2 face is 135 °.
Preferably, taperliner is additionally provided between insulator chain and cross-arm, is conducive to improving between insulator chain and cross-arm
Steadiness.
Preferably, the material of bird-proof cover and protective cover is rigid plastics, can effectively play insulating effect.
The beneficial effects of the utility model are：
(1) the distinctive ramp structure of cross-arm gold utensil and bird thorn bar, the perfect adaptation of bird cover, greatly reduce 10KV transmissions of electricity
The bird pest problem of circuit, reduces because number of times is overhauled in the power-off that bird pest causes；
(2) protective cover on shaft tower not only plays a part of anti-bird, and discharging rod thereon plays a part of to draw thunder, makes
Obtaining direct lightning strike lightning-caused breaking probability reduces, and so as to reduce the cost of power operation, has reached good economic benefit；
(3) reasonable in design, simple structure, it is easy to fabrication and installation is with low cost.
