Abstract
The utility model discloses a kind of graphite grounding body of lightning protection device, graphite pole is connected with the distribution of graphite mobile jib lateral wall circumference, spirality metal support is fixed with the outside of the graphite mobile jib, each graphite pole is separately fixed on metallic support.The utility model can make the stronger graphite of electric conductivity but without worrying its support strength, and spiral metal support all has good supporting role, not result in graphite mobile jib and the fracture of graphite pole.Spiral metal support not only plays electric action, and main function is to play a part of the strong electrically conductive graphite of support, even if metal is corroded or aoxidized, does not affect the normal function of strong electrically conductive graphite.As long as there is the integrality for ensuring that graphite in the support strength of metal, it is ensured that grounding function.
Description
Technical field
The utility model is related to the ground connection accessory in arrester technical field, and in particular to a kind of graphite of lightning protection device connects
Ground body.
Background technology
At present, lightning protection device mainly includes lightning rod, lead and grounding body.The grounding body of existing lightning protection device is substantially
, it is necessary to burying depth is big, workload is big, and efficiency is low for metalwork.After being corroded for a long time due to metal, earthing effect is deteriorated,
Grounding resistance is raised, and influences lightning protection function, and average life span is 2-5, and period needs to detect and changes, cumbersome.Graphite has
The characteristics of having anti-oxidant, corrosion-resistant and long service life, has recorded using graphite complexed metal in the shocking preventing technology document of part
Lightning-proof grounding body, but this composite construction is more complicated, technology difficulty is big, is contacted using between rear metal and graphite for a long time
Degradation, electric conductivity is deteriorated therewith, and it is very big resistivity that graphite is only relied on after metal loses conducting function as grounding body,
It is difficult to realize effective lightning protection effect.One of the reason for pure graphite is not directly used as into grounding body in conventional method is pure graphite
Resistivity is larger, and the graphite after hardness reduction tends to lose connection function because losing, and influences conductive effect.
Utility model content
The purpose of this utility model is directed to the problem and shortage that existing lightning-proof grounding body is present, there is provided a kind of lightning protection device
Graphite grounding body.
To achieve the above object, adopt the following technical scheme that：A kind of graphite grounding body of lightning protection device, including graphite master
Bar, graphite pole is connected with the distribution of graphite mobile jib lateral wall circumference, or reconnection has graphite pole on graphite pole, in institute
State and spirality metal support is fixed with the outside of graphite mobile jib, each graphite pole is separately fixed on metallic support.It is described
The top and bottom of spiral metal support are respectively arranged with fixed cover, and the upper and lower of graphite mobile jib is set in by fixed cover
End.Connected by metal fixing between each graphite pole and spirality metal support.
Beneficial effect：Design feature of the present utility model, it is possible to use the stronger graphite of electric conductivity but without worrying it
Support strength, the support of strong electrically conductive graphite of the present utility model can be supported by spiral metal support, either buried
Process, or the operational phase after burial, spiral metal support all have good supporting role, do not result in graphite mobile jib
It is broken with graphite pole.Even if indivedual graphite pole fractures caused by maloperation, in the connection function of spiral metal support
Under, the electric action contacted with ground can be also given full play to, spiral metal support not only plays electric action, main function
It is to play a part of the strong electrically conductive graphite of support, so the utility model relies primarily on main body of the strong electrically conductive graphite as ground connection, i.e.,
Metal is corroded or is aoxidized, do not affect the normal function of strong electrically conductive graphite.As long as the support strength of metal is present with regard to energy
Ensure the integrality of graphite, it is ensured that grounding function.
Brief description of the drawings
Fig. 1 is dimensional structure diagram of the present utility model.
Label 1 is graphite mobile jib in figure, and 2 is graphite pole, and 3 is spirality metal support, and 4 is metal fixing, and 5 is solid
Fixed set.
Specific embodiment
A kind of graphite grounding body of lightning protection device, referring to Fig. 1, graphite is connected with the lateral wall circumference distribution of graphite mobile jib 1
Pole 2, being reconnected on graphite pole 2 has graphite pole 2.
Spirality metal support 3, the top and bottom difference of spiral metal support 3 are fixed with the outside of graphite mobile jib 1
Fixed cover 5 is provided with, the upper and lower end of graphite mobile jib 1 is set in by fixed cover 5.
Each graphite pole 2 is separately fixed on metallic support 3, is passed through between each graphite pole 2 and spirality metal support 3
Metal fixing 4 is connected.
