Background technology
In current Phase of Electric Power Projects, in order to protect the safety of power transmission facility and power consumption equipment, personnel, reduce the loss of being struck by lightning and causing, electric tower often arranges grounding-for-lightning device, and wherein grounding electrode is the vitals that ground is connected with earth connection.At present, lightning protection electrode mostly is fixes non-metallic conducting material block 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, the contact area on this grounding electrode and ground is little, often need multiple grounding electrode to connect to use, and non-metallic conducting material block is in use easily broken and increase the gap with zinc-coated flat steel sheet body, cause grounding resistance unstable, easily produce lightning current counterattack.
Summary of the invention
The technical problems to be solved in the utility model is: in order to overcome above-mentioned middle Problems existing, provide a kind of grounding electrode for electric tower lightning protection, it is rational in infrastructure, have that structure is simple, easy to use, resistance value stablizes, the advantages such as contact area is large, effectively solve traditional grounding electrode non-metallic conducting material block and hold breakable problem.
The utility model solves the technical scheme that its technical problem adopts: a kind of grounding electrode for electric tower lightning protection, comprise plug and there is the metal sleeve of Two-ports structure, described plug, metal sleeve are mutually sheathed, and are filled with electrolyte between plug, metal sleeve; Two openends of described metal sleeve are respectively arranged with the first end cap and the second end cap, and what the outer wall of metal sleeve is provided with some circuluses stretches out block, and on metal sleeve, be provided with the through hole for electrolyte turnover; One end of described plug mutually abuts with the second end cap, and the other end of plug passes the first end cap and extraneous earth connection is interconnected.
As preferred scheme, described plug upper end is provided with the splicing ear for connecting earth connection.
As preferred scheme, described electrolyte is that the braiding of flexible graphite line is made.
As preferred scheme, described plug is that copper alloy is made.
As preferred scheme, described metal sleeve is integral structure with stretching out block.
As preferred scheme, the second described end cap is provided with the inserted link for strengthening conduction distance.
The beneficial effects of the utility model are: a kind of grounding electrode for electric tower lightning protection, comprise plug and metal sleeve, plug and metal sleeve are socketed and filling flexible graphite line between mutually, metal sleeve is provided with ring-type and stretches out block and through hole, stretch out block and increase contact area, expand after graphite line water suction, electrolyte extends increasing contact area further to surrounding and reduces resistance, not easily fragmentation under the clamping of plug and metal sleeve, plug bottom abuts the second end cap with inserted link, can reduce the degree of depth of digging pit when constructing; It is rational in infrastructure, and have that structure is simple, easy to use, resistance value stablizes, the advantages such as contact area is large, effectively solve traditional grounding electrode non-metallic conducting material block and hold breakable problem.
Accompanying drawing explanation
