Description
Technical field
The utility model relates to the efficient electric resistance reducing grounding device of a kind of distribution, belongs to Grounding Technology of Modern Power System field.
Background technology
Distribution line is the one-level of closer user in electric power system, is responsible for the important duty of powering to industrial and agricultural production, resident's daily life, has that line construction complexity, circuit total amount are many, the feature of broad covered area.There is the thought of the light distribution of major network emphatically over a long period of time, cause the shocking preventing technology level of current distribution all to there is larger gap compared with major network.Distribution line is generally without special lightning protection and grounding measure, and even some distribution shaft tower does not have earthing device, is not only vulnerable to the impact of direct lightning strike, also can cause insulator arc-over because of induced lightening simultaneously.For preventing counterattack thunder on the impact of distribution line, mainly still from ground connection, resistance is started with, if earth resistance is defective, when lightning current flows into shaft tower, due to the pressure drop on the inductance of shaft tower or other down conductors and pole tower ground resistance, such head of mast potential value may be enough to line insulation is strikeed back, and still causes tripping operation power outage.
Therefore, develop a kind of earth resistance of earthing device for reduction distribution electric power line pole tower earthing device being applicable to distribution electric power line pole tower, improve the resistance to thunderbolt level of distribution shaft tower, reduce the stroke-incidence rate of distribution transmission line, improve power supply reliability and the fail safe of distribution, be with a wide range of applications.
Summary of the invention
The purpose of this utility model is, overcomes the deficiency that resistance technology falls in existing distribution ground connection, proposes a kind of efficient electric resistance reducing grounding device of distribution being applicable to distribution electric power line pole tower, solves distribution electric power line pole tower lightning protection problem.
The technical solution of the utility model is, the efficient electric resistance reducing grounding device of a kind of distribution is made up of metal electrode, lead-out wire, grading ring, efficient resistance-lowering material and tup.The round tube shape structure of described metal electrode to be one end be filled circles conehead, one end open, below metal electrode upper, open end, tube wall has spiracle, metal electrode bottom has fluid hole on cone headed tube wall; Efficient resistance-lowering material is filled in the pipe of metal electrode; The opening lower position of lead-out wire and grading ring difference connection metal electrode; Tup is arranged on metal electrode opening part.
Described lead-out wire adopts stainless steel twisted wire, can be connected with horizontal grounding net.
Described spiracle makes interior filler fully can absorb moisture in soil, and in keeping, filler is moistening; Described fluid hole makes the resistance filler that efficiently falls in electric metal electrode be released slowly in soil.
Described grading ring can effectively reduce earth potential liter, guarantees personal security.
Described conehead can effectively reduce metal electrode hammering and enter resistance in soil, and tup can available protecting metal electrode.
The beneficial effects of the utility model are, be filled with in ground metallic electrode of the present utility model and efficiently fall resistance filler, and make the resistance filler that efficiently falls in electric metal electrode be released slowly in soil by the fluid hole on metal electrode, greatly reduce earth resistance, improve the resistance to thunderbolt level of distribution shaft tower.Be provided with grading ring in the utility model, can effectively reduce earth potential liter, guarantee personal security.Have employed conehead and hammehead structure in the utility model, be beneficial to the installation of metal electrode.The utility model structure is simple, easy to install and use, can be used for distribution electric power line pole tower lightning protection.
