Description
Technical field
This utility model is related to grounding-for-lightning device technical field and in particular to a kind of soft graphite lightning protection bluk recombination
Down conductor.
Background technology
Lightning protection generally comprise consisting of part：(1) thunder and lightning receiving device：Directly or indirectly accept the gold of thunder and lightning
Belong to bar (arrester), such as discharging rod, lighting proof strip (net), aerial earth wire and spark gap etc.；(2) earth lead (downlead)：Thunder and lightning connects
The metallic conductor being connected with grounding device by device；Its effect is that the lightning current on thunder and lightning receiving device is delivered to ground connection
On device, earth lead typically adopts round steel or band steel composition.(3) grounding body：Including the soil around grounding device and device or
Concrete, effect is that thunder-strike current is leaked into the earth effectively, and existing frequently-used grounding device has horizontal grounding pole, vertical ground connection
Pole, prolongation earthing pole and foundation grounding pole.
Wherein, earth lead can be divided into lightning protection downlead and down conductor, and lightning protection downlead refers to anti-positioned at eminence
Thunder connects the connecting line between lightning-proof grounding body for other metal objects dodging on device or building；The distance between with grounding body
Relatively long.Down conductor refers to one section of very short part welding out on grounding body, for lightning protection downlead phase
One section connecting.Generally it is understood that：Part more than breaking of contact is called lightning protection downlead, the part below breaking of contact
Do down conductor.
Software graphite earthing pole and software graphite grounding module are a kind of novel metalloid conductive materials, stable performance, from
Body resistivity is low, high-low temperature resistant, acid-alkali-corrosive-resisting, the electric current of resistance to large impact, and material character does not change.Software graphite is grounded mould
Block increases several times with respect to software graphite ground connection polar diameter, amasss with soil contact and increases, in the case of same fault electric current,
Fault current can be imported the earth by software graphite grounding module faster.In addition software graphite grounding module is arranged on software graphite
With multichannel dispersed placement on earthing pole, in multi-thunder area, software graphite grounding module has good reduction heavy current impact
Effect.Particularly in the mountain area having inconvenient traffic, no electric, soil resistivity is high, connect using software graphite earthing pole and software graphite
The method that ground module combines, can better meet design requirement, and easy construction, reduce excavated volume, reduce expense.
Utility model content
The purpose of this utility model is to provide a kind of soft graphite lightning protection bluk recombination down conductor, soft for solving
The property easily impaired problem of thunder-preventing graphite grounding body downlead sheath so that down conductor is high temperature resistant, anti-cutting, corrosion-resistant, make
