Abstract

The utility model relates to a lightning arrester, and belongs to the field of lightning protection facilities. The lightning arrester comprises a base. A plurality of installation rods are fixed at the upper end of the base in an upward inclination mode, cluster-like lightning rods are fixed at the end portions of the installation rod, a bird-prevention stab is fixed at the bottom of the base, the bird-prevention stab is circumferentially installed on the base, the height of the bird-prevention stab is lower than the height of the bottoms of the lightning rods, a stabilizer bar is arranged between neighboring lightning rods, and the two ends of each stabilizer bar are respectively fixed on the lightning rods so as to form a triangle. The lightning arrester has the advantages of high efficiency, low cost and simple installation.

Description

Lightning arrester
Technical field
The utility model relates to a kind of lightning arrester, belongs to lightning protection facility field.
Background technology
At present, the anti-bird pest of transmission tower is is generally installed and used occupy-place formula bird-resistant above shaft tower, and this installation cost is lower, installs simply, and installation rate is higher; Shaft tower lightning protection measures mainly adopts lightning conducter, and its shielding angle design load generally adopts 20-30 degree, and shielding angle is less, and its lightning protection effect is more obvious.But be subject to the restriction of the factors such as shaft tower model, landform, wire, it is enough little that shielding angle can not design, and the protection range to wire of lightning conducter is restricted, the area frequently of being struck by lightning in mountain area etc., lightning protection effect is not obvious.According to negative angle protection, by installing lightning rod additional at overhead wire side pylon, make to reduce with the shielding angle value of outboard wire, improve lightning protection effect, reduce line tripping rate.But current lightning rod is single attracting thunder needle, to draw thunder DeGrain, and on shaft tower, install respectively bird-resistant and lightning rod additional simultaneously, efficiency is low, cost is high, it is loaded down with trivial details to install.
Utility model content
According to above deficiency of the prior art, the technical problems to be solved in the utility model is: provide that a kind of efficiency is high, cost is low, simple lightning arrester is installed.
Lightning arrester described in the utility model, comprise base, base upper end is fixed some mounting rods obliquely, mounting rod end fixed tuft shape lightning rod, the fixing bird-resistant in base bottom, bird-resistant is circumferentially arranged on base, bird-resistant overhead height is lower than lightning rod bottom level, between adjacent lightning rod, establish stabiliser bar, stabiliser bar two ends are separately fixed on lightning rod, form triangle.
Globular pinhead is established in lightning rod upper end, and in the time of thundery sky, globular pinhead, due to point discharge effect, first discharges thunder and lightning to lightning rod.
Stabiliser bar is engineering plastics material, and not yielding, the life-span is long, nonflammable.
Coated red pigment on bird-resistant, has certain deterrent effect to birds, prevents that birds are close.
Operation principle and process:
When work, in the time of thundery sky, globular pinhead is due to point discharge effect, first thunder and lightning is discharged to lightning rod, stabiliser bar is lightning rod firmly, can not be offset at strong wind weather lightning rod, prevent that the shielding angle of wire span centre drift from can exceed the shielding angle at shaft tower place, cause circuit to suffer thunderbolt to cause trip accident, by ground connection guide wire and earthing device, thunder-strike current is introduced to the earth, thereby avoid the generation of the around shocking to wire and the counterattack thunder to shaft tower, bird-resistant can prevent that birds are close, ensure that line security and protection birds are not injured by thunder and lightning.
The beneficial effect that the utility model compared with prior art had is:
Lightning arrester described in the utility model, by lightning protection and two effective combinations of protective device of anti-bird pest, stabiliser bar is lightning rod firmly, prevents that circuit from suffering thunderbolt to cause trip accident, saves cost, simple in structure, easy to install.
Brief description of the drawings
Fig. 1 is the utility model embodiment schematic diagram.
In figure: 1, globular pinhead; 2, lightning rod; 3, stabiliser bar; 4, base; 5, bird-resistant; 6, mounting rod.
Embodiment
Below in conjunction with accompanying drawing, embodiment of the present utility model is described further:
As shown in Figure 1, lightning arrester described in the utility model, comprise base 4, base 4 upper ends are fixed some mounting rods 6 obliquely, mounting rod 6 end fixed tuft shape lightning rods 2, bird-resistant 5 is fixed in base 4 bottoms, bird-resistant 5 is circumferentially arranged on base 4, and bird-resistant 5 overhead heights, lower than lightning rod 2 bottom level, are established stabiliser bar 3 between adjacent lightning rod 2, stabiliser bar 3 two ends are separately fixed on lightning rod 2, form triangle.
Globular pinhead 1 is established in lightning rod 2 upper ends, and in the time of thundery sky, globular pinhead 1, due to point discharge effect, first discharges thunder and lightning to lightning rod.
Stabiliser bar 3 is engineering plastics material, and not yielding, the life-span is long, nonflammable.
Coated red pigment on bird-resistant 5, has certain deterrent effect to birds, prevents that birds are close.
Operation principle and process:
When work, in the time of thundery sky, globular pinhead 1 is due to point discharge effect, first thunder and lightning is discharged to lightning rod, stabiliser bar 3 is lightning rod 2 firmly, can not be offset at strong wind weather lightning rod 2, prevent that the shielding angle of wire span centre drift from can exceed the shielding angle at shaft tower place, cause circuit to suffer thunderbolt to cause trip accident, by ground connection guide wire and earthing device, thunder-strike current is introduced to the earth, thereby avoid the generation of the around shocking to wire and the counterattack thunder to shaft tower, bird-resistant 5 can prevent that birds are close, ensure that line security and protection birds are not injured by thunder and lightning.
