Abstract
The utility model discloses a lightning protection earth electrode based on modified graphite. The section face of the earth electrode is provided in order from the interior part to the exterior part with a stainless steel twisted line, a soft graphite conducting layer and a cellulose glue solution protecting film; both ends of the earth electrode body are provided with metal connection heads. Each metal connection head comprises a cable hoop in connection with the earth electrode body and a connection plate arranged at the outer part of the cable hoop. The connection plate is provided with a double screw hole. The earth electrode of the utility model has a reasonable structure, small electric impedance and a low electric resisting rate. Capable of discharging lightning current rapidly, the earth electrode is safe and reliable, thus, ensuring it has a long service lifetime.
Description
Technical field
The utility model relates to shocking preventing technology field, especially relates to a kind of lightning-proof grounding body based on modified graphite.
Background technology
At present, it is large that China adopts stainless steel and graphite material to manufacture toughness, can circle around, the lightning-proof grounding body of convenient carrying construction, the main technical scheme that adopts patented product ZL201220340996.7, this technology exists problem in actual applications, if inner stainless steel wire and outside graphite guide electric wire are by the volume structure that ropes, bending winding degree is large, the electrical impedance producing, resistivity is large, easily there is lightning current counterattack accident, and graphite cotton rope outer surface is exposed, easily make the electrically conductive graphite layer that the soft intensity of matter is low be scratched, damage, service time is short, cause earth electrode resistance to increase, the speed that lightning current is released to the earth is slow, produce potential safety hazard, only establish metal connector in one end of product, cause ground network assembly and connection difficulty.
Summary of the invention
The utility model object is to provide a kind of rational in infrastructure, lightning current fireballing lightning-proof grounding body based on modified graphite of releasing.
For achieving the above object, the utility model can be taked following technical proposals:
Lightning-proof grounding body based on modified graphite described in the utility model, comprises earth electrode body; Described this body section of earth electrode is followed successively by stainless steel twisted wire, flexible graphite conductive layer and cellulose glue protecting film from the inside to the outside, is respectively arranged with metal connector at described earth electrode body two ends.
Described metal connector comprises the cable cuff being connected with earth electrode body, and is arranged on the connecting plate of described cable cuff outside, offers two screws on described connecting plate.
Speed rational in infrastructure, that electrical impedance is little, resistivity is low, lightning current is released that the utility model advantage is is fast, safe and reliable, service time is long.
Brief description of the drawings
Fig. 1 is structural representation of the present utility model.
Fig. 2 is the sectional drawing of the utility model earth electrode body.
Embodiment
As shown in Figure 1, 2, the lightning-proof grounding body based on modified graphite described in the utility model, comprises earth electrode body; Described this body section of earth electrode is followed successively by stainless steel twisted wire 1, flexible graphite conductive layer 2 and cellulose glue protecting film 3 from the inside to the outside, is respectively arranged with metal connector at described earth electrode body two ends; Described metal connector comprises the cable cuff being connected with earth electrode body, and is arranged on the connecting plate 4 of described cable cuff outside, offers two screws on described connecting plate 4.The thickness of flexible graphite conductive layer 2 is 3mm, is formed by the expanded graphite extruding of high-carbon, flexibility, the large graphite scale of 50 order, makes low intensive graphite leidosome become high-intensity flexible graphite electric conductor; The diameter 14mm of stainless steel twisted wire 1, is twisted into by the stainless steel wire of 7 diameter 2mm; The thickness of cellulose glue protecting film 3 is 1mm, conducts electricity after absorbing hydrone in soil, dries film forming after brushing.Compound rear toughness is high, intensity is large, resistivity is low, corrosion-resistant, resistant to rust,, tension good with soil contact, resistance to compression, folding, long-term-effective dropping resistance.
