Technical field
The present invention relates to ground network device technique field, be specifically related to a kind of flexible graphite ground network.
Background technology
At present, most ground network is all metal grounding network, metal grounding network is generally designed to the useful life of 20 ~ 30 years when burying underground, but find in actual use procedure, some metal grounding networks (as mild steel ground network) are in operation after 3 ~ 5 years, and serious corrosion has occurred the partial earthing metal surface in ground network.Metal grounding network is generally be welded by multiple earth electrode, its corrosion mainly occurs in the parts such as the pad between the earth electrode of metal material itself, earth electrode, this metal grounding network cannot bear very large impulse current after seriously corroded, make ground network, electrical network is faced with great operation risk, operation maintenance personnel is also very dangerous in the course of the work.Along with increasing of the electric power accident caused due to ground net corrosion, people more and more pay attention to the corrosion of electric power grounding grid and anticorrosion research now.
In correlation technique, also the exploitation to metal or nonmetallic ground network new material is had at home and abroad, such as copper, galvanized steel, plasma etc., but, although copper grounding grid has high conductivity, high anti-corrosive properties, copper covered steel mechanical strength advantages of higher, and copper itself is expensive and can accelerate other corrosions of metal, and after adopting the mode of welding to connect between copper earth electrode, whole ground network all can increase contact resistance at these pad places, and electric conductivity is deteriorated.
Summary of the invention
The object of the present invention is to provide the ground network of a kind of antiseptic property, electric conductivity excellence.
To achieve these goals, the embodiment of the invention discloses a kind of flexible graphite ground network, described flexible graphite ground network comprises multistage flexible graphite conducting wire and the metal sleeve for crimping the described flexible graphite conducting wire that continues, one end crimping of described flexible graphite conducting wire is anchored in described metal sleeve, and flexible graphite conducting wire described in multistage is continued by described metal sleeve and is connected.
Further, the madial wall of the close port of described metal sleeve is provided with multiple barb for clamping described flexible graphite conducting wire, the bill portion of described barb is away from the port of described metal sleeve.
Further, also comprise the sealing shroud of the junction being set in described metal sleeve and described flexible graphite conducting wire, the internal diameter of one end of described sealing shroud and the external diameter of described metal sleeve match, and the internal diameter of the other end of described sealing shroud and the external diameter of described flexible graphite conducting wire match.
Preferably, described metal sleeve is stainless steel sleeve pipe.
Alternatively, described metal sleeve comprises yi word pattern sleeve pipe, T font sleeve pipe and cross sleeve pipe.
The beneficial effect that technical scheme provided by the invention is brought is:
Original metal material earth electrode is replaced by using flexible graphite conducting wire, ground network is made to have more excellent antiseptic property, simultaneously, crimped interconnected between many flexible graphite conducting wires by metal sleeve, graphite wire is made to contact tight difficult drop-off with the madial wall of metal sleeve, the contact resistance being interconnected at tie point place relative to traditional welding is less, enhances the electric conductivity of ground network.
Accompanying drawing explanation
In order to be illustrated more clearly in the technical scheme in the embodiment of the present invention, below the accompanying drawing used required in describing embodiment is briefly described, apparently, accompanying drawing in the following describes is only some embodiments of the present invention, for those of ordinary skill in the art, under the prerequisite not paying creative work, other accompanying drawing can also be obtained according to these accompanying drawings.

Wherein, Reference numeral is: 1, flexible graphite conducting wire; 2, metal sleeve; 3, barb; 3a, bill portion; 4, sealing shroud.
Embodiment
Below in conjunction with the drawings and specific embodiments, the invention will be further described:
As shown in Fig. 1 ~ 3, the invention provides a kind of flexible graphite ground network, this flexible graphite ground network comprises multistage flexible graphite conducting wire 1 and the metal sleeve 2 for crimping the flexible graphite conducting wire 1 that continues, wherein, one end crimping of flexible graphite conducting wire 1 is anchored in metal sleeve 2, and multistage flexible graphite conducting wire 1 is continued by metal sleeve 2 and is connected.
Particularly, in practice of construction process, a ground network may include multiple earth electrode, also be the multistage flexible graphite conducting wire 1 in the application, the whole ground network of interconnected formation between these earth electrodes, in the present embodiment, connected by metal sleeve 2 between each section of graphite wire, and according to different construction needs, sometimes need two graphite guide ends interconnected, sometimes need the three even termination of four graphite wires interconnected, this just needs metal sleeve 2 to have multiple pattern, such as be with the yi word pattern sleeve pipe of two ports, may be used for connection two wires, such as be with again the T font sleeve pipe of three ports, may be used for connection three wires.In the present embodiment, mode by crimping between metal sleeve 2 with flexible graphite conducting wire 1 is connected, also after namely in the port termination of flexible graphite conducting wire 1 being inserted in metal sleeve 2, the similar means such as hydraulic tongs also can be used to be compressed by sleeve pipe, make flexible graphite conducting wire 1 with metal sleeve 2 close contact and can not deviate from metal sleeve 2.
Wherein in a kind of implementation, the madial wall of the close port of metal sleeve 2 is provided with multiple barb 3 for clamping flexible graphite conducting wire 1, the bill portion 3a of barb 3 is away from the port of metal sleeve 2.
Particularly, flexible graphite conducting wire 1 is being inserted in after in metal sleeve 2, and wire can be caught on by barb 3, and the bill due to barb 3 is towards the one end away from sleeve port, and wire can be reversed to hook and not easily come off from port.
Further, in another kind of implementation, this flexible graphite ground network can also comprise the sealing shroud 4 of the junction being set in metal sleeve 2 and flexible graphite conducting wire 1, the internal diameter of one end of sealing shroud 4 and the external diameter of metal sleeve 2 match, and the internal diameter of the other end of sealing shroud 4 and the external diameter of flexible graphite conducting wire 1 match.
