The lightning protection grounding electrode body of the utility model consists of a conductive carbon fiber tensile rib arranged at a center inside of the lightning protection grounding electrode body, a carbon fiber graphite composite conductor wire layer arranged outside of the rib, and a carbon fiber braiding conductive anti-compression sheath arranged on an external surface of the carbon fiber graphite composite conductor wire layer, wherein one end of the carbon fiber braiding conductive anti-compression sheath is provided with a double-bolt-hole metal joint connected with electrical equipment. The lightning protection grounding electrode body of the utility model has the advantages of reasonable structure, high strength, scrape resistance, no falling, durability, tension resistance, compression resistance, uneasy damage, easy production and manufacture, labor saving, time saving, material saving, low resistivity, large use scope, firm connection, safety and reliability.
Description
Technical field
The utility model relates to a kind of lightning protection polar body.
Background technology
The lightning protection polar body of China's graphite cotton rope type mainly is the ZL200920027944.2 patented product at present.It is made up of inner conductive graphite core and core outer surface electrically conductive graphite line braiding conductive jacket, and an end that is connected with electric equipment is established joint.This product exists problem; Low like: the intensity of graphite line, be prone to break, difficulty when weaving conductive jacket, take a lot of work, time-consuming, waste material; The graphite phosphorus sheet conductive layer of jacket surface be prone to scratching broken, come off, be not durable, influence the lightning current speed of releasing, produce potential safety hazard; The low only 26.3Mpa of the tensile strength of product is prone to break, and the low only 31.7Mpa of compression strength is prone to damage by pressure, and the resistivity of 0.25 Ω .m is high, uses restricted, scope is little, the joint of single screw is connected not firm with electric equipment, easy activity is dangerous.
Summary of the invention
The purpose of the utility model provides a kind of lightning protection polar body; Prior art intensity is low to overcome, braiding difficulty, take a lot of work, time-consuming, waste material, the electrically conductive graphite layer be prone to scratching broken, come off, influence the lightning current speed of releasing, generation potential safety hazard; Tension, compression strength are low; Be prone to break, damage by pressure, resistivity is high, use is restricted, scope is little, connects not firm, easy movable, uneasy congruent problem.
The utility model technical scheme: the lightning protection polar body is made up of carbon fiber and graphite composite conducting line layer and outer surface carbon fiber knit conduction resistance to compression sheath outside inside center conductive carbon fibre tension muscle and the muscle, and an end that is connected with electric equipment is provided with two bolt hole metal joints.
The remarkable advantage of the utility model be rational in infrastructure, intensity is big, anti-scratching, do not come off, durable; Tension, resistance to compression are difficult for breaking, damaging by pressure, are prone to the manufacturing, saving of labor, save time, save material; Resistivity is low, use is unrestricted, scope is big, is connected firmly, safe and reliable.
