Abstract

The utility model discloses an environment friendly through ground wire having prefabricated branches. The through ground wire includes a through ground wire trunk, a highly conducting connection bodies and through ground wire branches. The through ground wire branches connect with the through ground wire trunk. The highly conducting connection bodies wrap connection points of the through ground wire trunk and the through ground wire branches. The environment friendly through ground wire having the prefabricated branches in the utility model is suitable for applying in a comprehensive grounding system of electrified railway. Since the ground wire has prefabricated branches, the grounding branches of the through ground wire can be prefabricated and formed in production. The environment friendly through ground wire having the prefabricated branches in the utility model is also a flexible cable having shape memory and has performances of no environmental pollution, high conductivity, low temperature resistance and the like.

Description

A kind of prefabricated branch environment-friendly type Through ground wire
Technical field
The utility model relates to electric power system, specifically is a kind of Through ground wire, and it is specially adapted to need on backbone, to pick out the railway combined grounding system of ground connection branch line.
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.
The utility model content
The utility model technical problem to be solved is the deficiency to 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 utility model 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; Said Through ground wire branch connects the Through ground wire trunk, and high conductive attachment body is wrapped in the junction of Through ground wire trunk and branch thereof.
In the utility model, preferably, said 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.
In the utility model, preferably, said high conductive attachment body is made up 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 through injection molding apparatus.
In the utility model, preferably, said Through ground wire branch is made up of the 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.
The said prefabricated branch of the utility model 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 accompanying drawing and embodiment the utility model is done specifying further.
Be illustrated as the prefabricated branch environment-friendly type Through ground wire of the utility model.
Embodiment
The prefabricated branch of the utility model environment-friendly type Through ground wire is 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 with Through ground wire branch 3, is coated on the outside by high conductive jacket.
The utility model provides the thinking and the method for a kind of prefabricated branch environment-friendly type Through ground wire; The method and the approach of concrete this technical scheme of realization are a lot, and the above only is the preferred implementation of the utility model, should be understood that; For those skilled in the art; Under the prerequisite that does not break away from the utility model principle, can also make some improvement and retouching, these improvement and retouching also should be regarded as the protection range of the utility model.The all available prior art of each component part not clear and definite in the present embodiment realizes.
