Abstract
The utility model discloses an intelligent excitation controllable discharge lightning arrester, which comprises discharge needle heads, discharge needles, a bottom support frame and a grounding body. The lightning arrester is characterized by also comprising an intelligent excitation device; the intelligent excitation device is connected with the discharge needles by a needle rod connecting seat and is connected with the bottom support frame by an excitation device connecting body; the intelligent excitation device comprises an upper excitation contact terminal and a lower excitation contact terminal and an insulation tube for fixing the upper excitation contact terminal and the lower excitation contact terminal, and a discharge gap exists between the upper excitation contact terminal and the lower excitation contact terminal; the upper excitation contact terminal and the lower excitation contact terminal are hemispherical, and the range of the discharge gap is 1.0 to 8mm. Two discharge needle heads and two discharge needles are arranged, and the included angle between the two discharge needles is 60 degrees. The lightning arrester automatically excites up lightning by the intelligent excitation device so that the thundercloud discharge current and the induced overvoltage are greatly reduced, and thereby, lightning stroke damages on transmission lines and equipment are reduced or even avoided.
Description
Technical field
The utility model relates to a kind of lightning protection device, relates in particular to a kind of intelligence that is applied on power system transformer substation and the various high-rise and excites the controlled discharge lightning arrester.
Background technology
Thunder and lightning is the violent electric discharge phenomena of charged cloud layer to above ground structure and the earth, and powerful lightning current can do great damage to building and equipment.Since 18 th century America scientist Franklin invention conventional lightning conductors, the research of human control damage to crops caused by thunder is also in constantly exploring.Conventional lightning conductor produces the development that corona effect is unfavorable for the guide at the needle point place, be the passive thunder that draws, and causes the generation of high-voltage transmission line lightning stroke tripping operation fault.
The utility model content
Problem to be solved in the utility model provides and has a kind ofly overcome that the intelligence of technical problem excites the controlled discharge lightning arrester in the prior art.
The technical solution of the utility model is: a kind of intelligence excites the controlled discharge lightning arrester, comprise discharge syringe needle, spray point, bottom support frame and earth electrode, it is characterized in that, also comprise intelligent excitation apparatus, be connected with spray point by the shank Connection Block, be connected with the bottom support frame by the excitation apparatus connector; Described intelligent excitation apparatus comprises and excites contact and the fixing insulated tube that excites contact up and down up and down that there is discharging gap in described exciting up and down between the contact; The described contact that excites up and down is a hemisphere, and the scope of discharging gap is 1.0-8mm.Described discharge syringe needle and spray point are two, and the angle between two spray points is 60 °.
This product of lightning arrester of the present utility model excites up thunder automatically by intelligent excitation apparatus, greatly reduces thundercloud discharge electric current and induction overvoltage, thereby protects transmission line and equipment minimizing and avoid suffering lightning damage.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
Embodiment
Below in conjunction with drawings and Examples, the utility model is described in further detail.
Intelligence of the present utility model excites guide's lightning rod that discharges, comprise discharge syringe needle 1, spray point 2, bottom support frame 4 and earth electrode, intelligence excitation apparatus 3 is between spray point 2 and bottom support frame 4, intelligence excitation apparatus 3 is connected with spray point 2 by shank Connection Block 5, is connected with bottom support frame 4 by excitation apparatus connector 6.Described intelligent excitation apparatus 3 comprises and excites contact and the fixing insulated tube that excites contact up and down up and down that there is discharging gap in described exciting up and down between the contact; The described contact that excites up and down is a hemisphere, and the scope of discharging gap is 1.0-8mm.Described discharge syringe needle and spray point are two, and the angle between two spray points is 60 °.
Intelligence excitation apparatus 3 is positioned at the below of two spray points.When the thundercloud electric field was low, intelligent excitation apparatus 3 was by discharge syringe needle 1 savings thundercloud electric field energy, because the buffer action of intelligent excitation apparatus, spray point syringe needle above earth potential is in quick condition, and is little with the potential difference of ambient atmosphere.Under the more weak situation of thundercloud electric field, effectively prevented the appearance of corona.When the thundercloud electric field reaches certain numerical value, during the intensity that takes place near thunderbolt, gap discharge, electric field distorts near the instantaneous generation above earth potential of needle body, needle body, helps the discharge that makes progress from the top development of discharge needle body.Behind the gap breakdown, there is a spark to produce immediately, causes the thunder and lightning guiding needle body discharge earlier of development earthward automatically to the upper space discharge at the needle point top.When initiation was unsuccessful, gap discharge stopped, and needle body returns to the above earth potential quick condition, the thunder and lightning guide by and syringe needle between electric capacity charged in the gap, puncture for the second time until the gap, and repeat above process, so circulation is until the guiding needle body discharge earlier of successful triggered lightning.Adopt the design of two spray points to make to discharge the guide efficient that success causes higher.
Be that intelligence of the present utility model excites this upwards guide of controlled discharge lightning arrester can directly develop into the up lightning of formation in the thundercloud, also can form the connection guide aloft with the descending guide's interception that is developing.Thereby the big electric current that will be struck by lightning is converted into little electric current, and significantly reduces the steepness of thunder-strike current and reduce shielding.Simultaneously, owing to the shielding action of guide that make progress to ground object, the induction overvoltage that when also having reduced thunderbolt ground object has been produced.Design consider to satisfy exchange 110kV～1000kV, direct current ± 500kV ~ ~ ± install and use on the iron tower column foot of 800kV transmission line.Bottom support frame at different field of employment design different sizes.
