Abstract
The invention discloses an environment-friendly through grounding wire capable of prefabricating a branch. The grounding wire comprises a through grounding wire trunk, a high-conductivity coupler and a through grounding wire branch, wherein the through grounding wire branch is connected with the through grounding wire trunk; and the joint of the through grounding wire trunk and the branch thereof is wrapped up with the high-conductivity coupler. The environment-friendly through grounding wire is applicable to the integrated grounding system of the electrified railway. The grounding wire has the function of prefabricating the branch, and the grounded branch of the through grounding wire can be prefabricated and molded during production. The shape memory flexible cable has environment-friendliness, high conductivity, low-temperature resistance and the like.
Description
?
Technical field
The present invention relates to electric power system, specifically is a kind of Through ground wire, and it is specially adapted to need to pick out the railway combined grounding system of ground connection branch line on backbone.
Background technology
The used equipment of railway combined grounding system comprises Through ground wire, earth terminal etc., this system realizes between each system, the equipment such as communication, signal, electric power, traction power supply, backflow that in order to guarantee equipotential connects, eliminate between distinct device, the system because the person and device security hidden danger that the potential difference existence causes are significant to the bullet train safety traffic.
At present, the laying method of Through ground wire is in the railway combined grounding system: at first the trunk with Through ground wire lays, and needs the place of ground connection at each system such as communication, signal, electric power and equipment, peels off the high conductive jacket of Through ground wire trunk, branch by hand.Then, on-the-spot trunk and branch with the manual crimping Through ground wire of Press Plier handle crimping place with the insulation single-coated foam again.This method site operation workload is big, and manual crimp strength is difficult to guarantee that the useful life of self-adhesive tape self is limited.
Summary of the invention
Technical problem to be solved by this invention is at the deficiencies in the prior art, provides a kind of easy for installation, reduces the prefabricated branch environment-friendly type Through ground wire of work on the spot amount.
The invention discloses a kind of prefabricated branch environment-friendly type Through ground wire, comprise Through ground wire trunk, high conductive attachment body and Through ground wire branch, the described Through ground wire connection Through ground wire master of branch, high conductive attachment body is wrapped in the junction of Through ground wire trunk and branch thereof.
Among the present invention, preferably, described Through ground wire trunk is made up of an environment-friendly type Through ground wire.Be used for the railway combined grounding system ground wire of unified ground connection completely, eliminated because the unsafe factor that potential difference causes between the distinct device has been realized the effective reliable protection to personnel and equipment.
Among the present invention, preferably, described high conductive attachment body is made of C type copper folder, high-conductive plastic jacket, and wherein C type copper folder is clipped together Through ground wire trunk and Through ground wire branch, is coated on the outside by high conductive jacket.C type copper folder is realized effective crimping of trunk and branch with mechanical crimping apparatus crimping.High-conductive plastic jacket is realized effectively protection such as the anti-copper oxidation of crimping place, corrosion by injection molding apparatus.
Among the present invention, preferably, described Through ground wire branch is made up of an environment-friendly type Through ground wire.Be used for each equipment of railway combined grounding system and be connected, guaranteed that earthing potential is identical between each equipment with the ground connection of Through ground wire trunk.
Prefabricated branch of the present invention environment-friendly type Through ground wire is applicable to railway combined grounding system, comprises by Through ground wire trunk, high conductive attachment body and Through ground wire branch constituting.This ground wire have can prefabricated branch function, the ground connection branch of Through ground wire can be pre-formed when producing, some drawbacks of avoiding site operation to bring.Prefabricated branch environment-friendly type Through ground wire also has environmental protection, high conductivity, performance such as low temperature resistant.Mechanical crimping is adopted in the connection place, adopts the high polymer sheath material to carry out the extrusion molding processing to the junction, thereby reduces the workload of site operation, guarantees the crimp strength of crimping place, has overcome the deficiency of self-adhesive tape processing crimping place.
Description of drawings
Below in conjunction with the drawings and specific embodiments the present invention is done further and to specify.
Be illustrated as prefabricated branch of the present invention environment-friendly type Through ground wire.
Embodiment
The prefabricated branch of the present invention environment-friendly type Through ground wire as shown in the figure, comprise by Through ground wire trunk 1, high conductive attachment body 2 and Through ground wire branch 3 and constituting, wherein Through ground wire branch 3 connects Through ground wire trunk 1, and high conductive attachment body 2 is wrapped in the junction of Through ground wire trunk and branch thereof.High conductive attachment body 2 is made up of high conductive jacket, C type copper folder, and wherein C type copper folder is clipped together Through ground wire trunk 1 and Through ground wire branch 3, is coated on the outside by high conductive jacket.
The invention provides the thinking and the method for a kind of prefabricated branch environment-friendly type Through ground wire; the method and the approach of this technical scheme of specific implementation are a lot; the above only is a preferred implementation of the present invention; should be understood that; for those skilled in the art; under the prerequisite that does not break away from the principle of the invention, can also make some improvements and modifications, these improvements and modifications also should be considered as protection scope of the present invention.The all available prior art of each component part not clear and definite in the present embodiment is realized.
