Abstract
The utility model discloses an intelligent excitation pilot discharge lightning arrester, which comprises a discharge needle head, a discharge needle, a bottom support frame and a grounding body also comprises an intelligent excitation device; the intelligent excitation device is connected with the discharge needle 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. 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, buildings and equipment are prevented from lightning stroke damages. The lightning arrester is applied to electrical power system transformer substations and various high-rise buildings.
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 guide's lightning rod that discharges.
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.Conventional lightning conductor produces the development that corona effect is unfavorable for the guide at the needle point place, lightning rod does not have the function that initiatively excites the guide to discharge yet simultaneously, is the passive thunder that draws, and causes the generation of high voltage substation lightning stroke trip fault.
The utility model content
Problem to be solved in the utility model provides and has a kind ofly overcome the take place frequently intelligence of technical problem of fault in the prior art and excite guide's lightning rod that discharges.
The technical solution of the utility model is: a kind of intelligence excites guide's lightning rod that discharges to comprise discharge syringe needle, spray point, bottom support frame and earth electrode, 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, and there is discharging gap in described exciting up and down between the contact, and the described contact that excites up and down is a hemisphere, and the scope of described discharging gap is 1.0-8mm.
Lightning rod of the present utility model excites up thunder automatically by intelligent excitation apparatus; greatly reduce thundercloud discharge electric current and induction overvoltage; thereby protection building and equipment avoid suffering lightning damage, are applied on power system transformer substation and the various high-rise.
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.
When the thundercloud electric field is low,, effectively prevented the appearance of corona because the buffer action of intelligent excitation apparatus 3 has reduced the potential difference of discharge syringe needle 1 with surrounding space.When the thundercloud electric field increases to intensity when taking place near thunderbolt, intelligent excitation apparatus 3 automatic conductings, the instantaneous increase of spray point needle body current potential is discharged to upper space by the spray point top, and the thunder and lightning that causes development earthward automatically guiding needle body earlier discharges.Promptly having under the situation of thundercloud, along with the reinforcement of thundercloud electric field, syringe needle is guided to the high field in the thundercloud on the discharging gap, reaches the puncture voltage that presets, gap breakdown, and generation excites the guide to discharge.Because the disruptive field intensity that presets far below the average disruptive field intensity of air, therefore can produce the effect that excites the guide in advance.Because the puncture energy in gap comes from the thundercloud electric field, does not need additional power source, is passive, non-maintaining.Design is considered to satisfy in 35kV～1000kV transformer station to install and use.And be applicable to that power plant high voltage station, skyscraper etc. need the place of strict lightning protection.Bottom support frame at different field of employment design different sizes.
Claims (3)
