Abstract
The utility model discloses a flexible graphite conducting wire, which comprises a graphite wire compact net sleeve, wherein a reinforcing mechanism is arranged in the net sleeve. As the graphite with excellent electrical conductivity is adopted as the grounding conductor, the specific resistance is extremely low; furthermore, the chemical property of the graphite enables the graphite to be excellently anticorrosive and stable, and satisfactorily protect the grounding net, so that the graphite is excellently durable; with the excellent impulse performance and the pressure balancing effect, not only is the power frequency ground resistance reduced, and but also the impulse grounding resistance is reduced; and as the flexible graphite conducting wire is bent and embedded underground, the contact area with the ground is enlarged, thereby ensuring the excellent pressure balancing effect, and reducing the contact voltage of step voltage and equipment.
Description
Technical field
The utility model belongs to lightning protection earthing line technology field, is specifically related to a kind of flexible graphite lead.
Background technology
Earth connection applies to various occasions widely, iron tower, building, large scale electrical power unit, and current common earth connection has following several.Earth rod is to take Singapore's technology that the cathode copper molecule of content 99.99% is covered on the low-carbon steel core uniformly as the doubly fast copper electroforming earth rod that reaches company's production in Zhenghai, makes the complete molecule combination of copper and steel.He has more than the copper bed thickness 0.25mm, and degree of adhesion is good, does not peel off characteristics such as (can be rolled threaded).Characteristics: 1. 2. corrosion resistance is strong for tensile strength big (up to 600 newton/square millimeters); can guarantee the excellent conductive capability of life-span existing copper of 3. copper electroforming earth rods more than 50 years; can save cost earth rod and ground connection netting twine again and adopt the Thermofusion welding agent welding; earthing device is under the protection of copper fully, becomes real non-maintaining earthing device.The copper electroforming earth rod is furnished with coaxial connector, hits accessories such as driving head and drill bit, also can use end point copper electroforming earth rod.Product regular size model is complete, can be according to customer requirement production.Although there is above advantage the phase, but a shortcoming that can not be ignored is, earth rod in depth down, production technology and mounting process complexity, installation cost and barred body cost are too high, and second, bar-shaped earth connection and underground contact area are little, compactness extent over the ground requires high, otherwise its conductive effect is bad, and safeguards inconvenience.The situation of graphite earth rod is similar with it.
The utility model content
The utility model provides that a kind of production technology is simple, parent ground property is good, with contact the big flexible graphite lead of electric area.
A kind of flexible graphite lead, it comprises the fine and close net of graphite line, in the described net reinforcing mechanisms is set.
Described reinforcing mechanisms is for to overlap the tight woven wire that combines with the graphite line dense mess.
Described reinforcing mechanisms is a glass fibre.
Described reinforcing mechanisms is a ceramic fibre.
Because the utility model adopts the splendid graphite of conductivity as earthing conductor, has extremely low resistivity, and the chemical property of graphite determines it to have anti-corrosive properties and stability preferably, ground network had good protective effect, thereby have well long-lasting; And also have good impact characteristics and all press effect, not only can reduce power frequency earthing resistance, can also reduce impulse earthed resistance; The flexible graphite lead is imbedded undergroundly with the shape of bending in addition, is equivalent to have increased the contact area with ground, thereby has caused well all pressure effects, has reduced the touch voltage of step voltage and equipment.Reinforcing mechanisms is set in the net, has improved the intensity and the toughness of flexible graphite line, avoid being subjected to tearing and the phenomenon that causes broken string takes place, solved a lot of manufacturers and installation company puzzlement earth connection problem for many years revolutionaryly.
Description of drawings
Below in conjunction with drawings and Examples the utility model is further described:
Fig. 1 is a structural representation of the present utility model.
Embodiment
As shown in Figure 1: a kind of flexible graphite lead, it comprises the fine and close net 1 of graphite line, and reinforcing mechanisms 2 is set in the described net.Because the utility model adopts the splendid graphite of conductivity as earthing conductor, has extremely low resistivity, and the chemical property of graphite determines it to have anti-corrosive properties and stability preferably, ground network had good protective effect, thereby have well long-lasting; And also have good impact characteristics and all press effect, not only can reduce power frequency earthing resistance, can also reduce impulse earthed resistance; The flexible graphite lead is imbedded undergroundly with the shape of bending in addition, is equivalent to have increased the contact area with ground, thereby has caused well all pressure effects, has reduced the touch voltage of step voltage and equipment.
Described reinforcing mechanisms is for to overlap the tight woven wire that combines with the graphite line dense mess.
Described reinforcing mechanisms is a glass fibre.
Described reinforcing mechanisms is a ceramic fibre.
Reinforcing mechanisms is set in the net, has improved the intensity and the toughness of flexible graphite line, avoid being subjected to tearing and the phenomenon that causes broken string takes place, solved a lot of manufacturers and installation company puzzlement earth connection problem for many years revolutionaryly.
