Abstract
The utility model discloses a kind of grounding-for-lightning device, comprise conduction stainless steel barred body, be fixed on the radio frequency body on described conduction stainless steel barred body; Described radio frequency body is by the graphite line sheet be coated on described conduction stainless steel barred body, and the graphite composite powder be filled in described graphite line sheet is formed; The two ends of described conduction stainless steel barred body seal respectively extends outside described graphite line sheet, offers electrical connection hole at the two ends of extending the conduction stainless steel barred body outside graphite line sheet respectively.The utility model advantage is that structure is simple, manufacturing expense is low.Freeze proof and toughness very much not cracky, long service life, wide accommodation.The utility model not sulfur compound, anticorrosive, can not to environment.Without the need to water curing during storage, resistance to strong lightning current impact capacity is strong, more than the 300KA that releases strong lightning current time≤25 μ s.Simultaneously carry, easy for installation.
Description
Technical field
The utility model relates to electrical grounding body, especially relates to grounding-for-lightning device.
Background technology
At present, major diameter lightning protection electrode mostly is and fixes non-metallic conducting material block structure on zinc-coated flat steel sheet body.After this non-metallic conducting material block adopts graphite, cement, bentonite in powder to be uniformly mixed by water, be fixed on zinc-coated flat steel sheet body by the mode of mechanical presses, its exist deficiency be: 1, manufacturing process complicated, time-consuming, discharge dust polluting environment, and need for water curing, waste water resource; 2, non-metallic conducting material block quantity of graphite is few, the general < 40% of phosphorus content, make that earth resistance is large, the ability of strong lightning current of releasing is low, release strong lightning current time of more than 300KA is long, general > 40 μ s,, there is potential safety hazard in easy generation counterattack accident; 3, non-metallic conducting material block needs to use inconvenient, waste water resource by water curing, heaviness, carrying and installation during storing in a warehouse, and large, the easy efflorescence fragmentation of poor toughness, fragility damages, and useful life is short; 4, non-metallic conducting material block is afraid of to freeze, and cold district is used and is restricted, the scope of application is little; 5, zinc-coated flat steel sheet body is not corrosion-resistant, and easy-to-rust damages and causes unstable, the easy rising of grounding resistance and produce lightning current counterattack accident.
Summary of the invention
The utility model object is to provide a kind of lightning protection electrode.
For achieving the above object, the utility model takes following technical proposals:
Grounding-for-lightning device described in the utility model, comprises conduction stainless steel barred body, is fixed on the radio frequency body on described conduction stainless steel barred body; Described radio frequency body is by the graphite line sheet be coated on described conduction stainless steel barred body, and the graphite composite powder be filled in described graphite line sheet is formed; The two ends of described conduction stainless steel barred body seal respectively extends outside described graphite line sheet, offers electrical connection hole at the two ends of extending the conduction stainless steel barred body outside graphite line sheet respectively.
Described conduction stainless steel bar body length is 1200 ㎜, diameter is 18 ㎜; Described graphite composite powder carbon content is 99%, and the particle diameter of graphite composite powder is 50-80 order; The thickness of described graphite line sheet is 3 ㎜.
The utility model advantage is that structure is simple, manufacturing expense is low.Freeze proof and toughness very much not cracky, long service life, wide accommodation.The utility model not sulfur compound, anticorrosive, can not to environment.Without the need to water curing during storage, resistance to strong lightning current impact capacity is strong, more than the 300KA that releases strong lightning current time≤25 μ s.Simultaneously carry, easy for installation.
