Description

The track traffic Through ground wire

Technical field

The utility model relates to track traffic synthetic grounding system field, is specifically related to a kind of track traffic Through ground wire.

Background technology

Through ground wire is a kind of integrated ground line that is applied to field of track traffic, is the protective earth of system mask, lightning protection, electric equipment etc.Through ground wire can make each working point electromotive force of electrical system of large-scale rail line be consistent basically; Make the system equipment grounding safety reliable; Eliminated because the current potential unsymmetrical current that the potential difference between the distinct device causes has been realized the effective reliable protection to personnel and equipment.

Summary of the invention

The utility model purpose provides a kind of track traffic Through ground wire, and this track traffic Through ground wire improves its intensity and hardness, improves the ability of the anti-extraneous external force damage of its mechanical and physical performance; Significantly reduce material cost.

For achieving the above object; The technical scheme that the utility model adopts is: a kind of track traffic Through ground wire; Comprise: first conductor that is positioned at the center; 6 second conductors are stranded to form second conductor layer in first conductive surface, and 12 the 3rd conductors are stranded to form the 3rd conductor layer in second conductor layer surface; The diameter range of said first conductor, second conductor and the 3rd conductor is: Φ 0.10-Φ 4.0mm.

It is following that technique scheme is further improved technical scheme:

1, in the such scheme, said first conductor, second conductor and the 3rd conductor are all for forming stranded conductor by 7 leads.

2, in the such scheme, the twisting pitch in said second conductor layer between second conductor is 60～80mm, and the twisting pitch in said the 3rd conductor layer between the 3rd conductor is 80～120mm.

Because the technique scheme utilization, the utility model compared with prior art has advantage and effect:

The Through ground wire of the utility model adopts double-layer structure to possess the functional characteristics of the electric power transfer of rail line grounding system, satisfies system's instructions for use; Pitch mutually combines in the employing 2, compares with original product, improves its intensity and hardness, improves the ability of the anti-extraneous external force damage of its mechanical and physical performance; Significantly reduce material cost.Because of product weight reduces by 70% compared with similar products, thereby significantly reduce transportation and construction cost.

Description of drawings

Accompanying drawing 1 is the utility model track traffic Through ground wire structural representation.

In the above accompanying drawing: 1, first conductor; 2, second conductor; 3, second conductor layer; 4, the 3rd conductor; 5, the 3rd conductor layer; 6, lead.

Embodiment

Below in conjunction with accompanying drawing and embodiment the utility model is further described:

Embodiment: a kind of track traffic Through ground wire comprises: 1,6 second conductor of first conductor 2 that is positioned at the center is stranded stranded in second conductor layer, 3 surface formation the 3rd conductor layers 5 in 3,12 the 3rd conductors of first conductor, 1 surface formation second conductor layer 4; The diameter range of said first conductor 1, second conductor 2 and the 3rd conductor 4 is: Φ 0.10-Φ 4.0mm.

Above-mentioned first conductor 1, second conductor 2 and the 3rd conductor 4 are all for forming stranded conductor by 7 leads 6

Twisting pitch in above-mentioned second conductor layer 3 between second conductor 2 is 60～80mm, and the twisting pitch in said the 3rd conductor layer 5 between the 3rd conductor 4 is 80～120mm.

When adopting above-mentioned track traffic Through ground wire, adopt double-layer structure to possess the functional characteristics of the electric power transfer of rail line grounding system, satisfy system's instructions for use; Pitch mutually combines in the employing 2, compares with original product, improves its intensity and hardness, improves the ability of the anti-extraneous external force damage of its mechanical and physical performance; Significantly reduce material cost.Because of product weight reduces by 70% compared with similar products, thereby significantly reduce transportation and construction cost.

The foregoing description only is the technical conceive and the characteristics of explanation the utility model, and its purpose is to let the personage who is familiar with this technology can understand content of the utility model and enforcement according to this, can not limit the protection range of the utility model with this.All equivalences of being done according to the utility model spirit change or modify, and all should be encompassed within the protection range of the utility model.
