Abstract
The utility model relates to a lightning protection grounding body and aims to solve problems with the prior art, wherein the problems are that a conventional grounding body is high in electrical impedance, heavy current counter-attacking accidents are liable to occur, braiding and processing are complicated, difficulties exist, labor, time, material and energy are wasted, internal graphite wires are loose without cohesion and liable to break and damage, a bare portion above the ground surface is liable to scratch and damage and is not durable, and safety hidden troubles are likely to happen. The lightning protection grounding body comprises twisted carbon fiber graphite composite conductive wires, a plastic sheath and a metal joint. The plastic sheath is sleeved on a bare portion which is located above the ground surface and is connected with an electrical device. The metal joint is extruded on a cable outer terminal sleeved with the plastic sheath, and is connected with the electrical device. The lightning protection grounding body is reasonable in structure, low in electrical impedance, simple in production process, low in resistivity, wide in using scope and high in strength. Moreover, the lightning protection grounding body is safe and reliable, enables labor, time and material and energy to be saved, is tension resistant, compression resistant and scratch resistant, and is durable and not liable to damage.
Description
Technical field
The utility model relates to a kind of lightning protection body.
Background technology
China mainly is the ZL200920027944.2 patented product with the lightning protection body of graphite line manufacturing at present, and it is made up of the conductive jacket of inner conductive graphite core and the braiding of outer surface electrically conductive graphite line, and an end that is connected with electric equipment is established joint.This product exists problem, the resistance Chinese People's Anti-Japanese Military and Political College that produces like: outer surface conductive jacket, when heavy current impact, is prone to take place the counterattack accident, braiding trouble, complex process, difficulty, time-consuming, waste material, the energy; Loose, the no cohesion of the graphite line of inner core, resistivity is big, the scope of application is little; Be prone to break, damage by pressure, the above part that is connected with electric equipment of ground surface is exposed, is prone to scratching and damages; Be not durable, produce potential safety hazard.
Summary of the invention
The purpose of the utility model provides a kind of lightning protection body; Overcoming the prior art resistance Chinese People's Anti-Japanese Military and Political College, be prone to take place big electric current counterattack accident, braiding trouble, complex process, difficulty, take a lot of work, time-consuming, waste material, the energy; Loose, the no cohesion of inner graphite line; Be prone to break and damage by pressure, ground surface damages, is not durable with the exposed easy scratching in top, produces problems such as potential safety hazard.
The utility model technical scheme: lightning protection body cable shape is formed by carbon fiber and graphite composite conducting line twisted; The above exposed part that is connected with electric equipment of ground surface is worn the plastic cement sheath, the metal joint that in the external termination extruding of the cable of wearing the plastic cement sheath, is connected with electric equipment.
The remarkable advantage of the utility model is rational in infrastructure, and electrical impedance is low, safe and reliable, and production technology is simple, the saving of labor, save time, save material, the energy, and resistivity is little, the scope of application is big, and intensity is big, tension, resistance to compression, anti-scratching, not fragile, durable.
